MX 6.1 W2K3 Installation Hangs
Hi All We have a completely fresh, pristine and virgin installation of Windows Server 2003 Standard, and we're trying to install MX 6.1 Pro onto it. Every time we try, it goes right through the installation to point of Installing Web Server Connectors... Then it pops up a cmd.exe window with nothing in it, and hangs. Forever! We've tried leaving it for over an hour, nothing happened. It wouldn't even respond to the Cancel button. So we killed the installer, deleted all CF files and went through the registry deleting anything matching Macromedia When we run it again, the same problem occurs. We've tried telling the installer to use the built-in web server, use only the default IIS web server, configure all IIS websites - same thing happens every time. Anyone else had this issue? Anyone got round it? Or is our shiny new Windows box just a big pile of doodoo? (no OS flamewars please - if it was up to me we'd certainly be using Apache as a webserver, probably on RedHat Enterprise, but it's not my call unfortunately) All help greatly appreciated Alistair Alistair Davidson Senior Technical Developer Headshift.com -- HEADSHIFT www.headshift.com T: 020 7357 7358 -- smarter simpler social Personal techie blog : http://instantbadger.blogspot.com [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]

You're saying that the install runs the web server configuration utility even if you choose the JRun web server during the installation? I've never seen that happen before. Hey, Dave, come on over to our place! You can watch it happening over and over again! ;D Anyway, Brandon Purcells tip about minimizing the ports which it scans seemed to do the trick, our server admin guy is happy once more.

RE: Regex Question: All punct except...
One solution I've used before in vaguely similar situations is to replace the / character with a placeholder, do the nice clean reg ex, then put the slashes back: myString = replace( myString, /, PLACEHOLDER, ALL ); myString = REReplace( myString, [[:punct:]], , ALL ); myString = Replace( myString, PLACEHOLDER, / ); but : - it's going to be slower than doing it all in one regex - you have to choose a placeholder that's never going to appear in your input string (I use something like donkeyshiftingpignudger, or other such blather) - it feels like a nasty kludge so I only use it when I have to (i.e. when I just don't have time to get the all-in-one reg ex working) [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]

RE: advice on structure and cfcs (petmarket related)
I figured if I could code something nice and clean somewhat along the lines of the petmarket it would be faster loading. Is that not the case? Yes, you can nearly always write something that's architected completely towards your specific app that runs a smidgeon faster than something like FB or Mach-II, but in my experience: - overhead of the FB3 framework is usually of the order of a couple of milliseconds at most. Mach-II tends to be a little more, but usually no more than 10ms or so in production mode. If you set it into production mode and you're still getting overheads of 1s or more, then there's something wrong with your code, or DB, or server setup, or something similar - Sean's example of MM using Mach-II being a case in point. - Squeezing a few extra milliseconds out of a page execution time has to be balanced against the gains in maintainability, extensibility, development/debug times, and learning curve for new team members that you get from using a standard methodology - If your app is poorly thought out, rushed, or sloppily implemented, it'll probably run like a two-legged-dog on mogadon whether you're using FB3, FB4, Mach-II, XFB, Struts, CF-Objects or your own entirely custom architecture. Ditto for its maintainability, extensibility, bug-fixing, etc etc etc. Just my two pennorth. ( If this ends up as yet another my framework is better than your framework flame war, I'm off to the pub! ;) ) Cheers, Alistair Alistair Davidson Senior Technical Developer Headshift.com -- HEADSHIFT www.headshift.com T: 020 7357 7358 -- smarter simpler social Personal techie blog : http://instantbadger.blogspot.com [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]
RE: advice on structure and cfcs (petmarket related)
I haven't seen the petmarket example, so I can't comment on that particular case, but I can say that - Yes, in general, that's a very bad thing. I'm not going to go into detail about WHY it's a bad thing, because I'll be rabbiting on for hours, but in practical it harms the flexibility, re-usability and maintainability of your code. The idea is to separate your backend from your frontend - or your Model from your Views, in MVC speak. This is achieved by an intermediary layer called the Controller. So your back-end CFCs are all self-contained - they don't know ANYTHING about the front-end display templates that actually define the interface. Fusebox ( www.fusebox.org http://www.fusebox.org/) was an attempt to achieve this degree of separation long before the advent of CFCs, Mach-II ( www.mach-ii.com http://www.mach-ii.com/) is probably the way to go if you want a standard way of doing it that harnesses the power of the CFC model. Hope that helps Al _ From: stylo stylo [mailto:[EMAIL PROTECTED] Sent: 10 August 2004 06:37 To: CF-Talk Subject: advice on structure and cfcs (petmarket related) I'm looking how to best structure an application and build it with cfcs. I'm looking at the petmarket example right now (cfml only, not the flash front end version). What do people feel in general about the way that application is structured? In particular, I'm wondering about the detailview.cfm which is called by the product.cfc detailview function and used to output the page. Isn't that a bad thing? I would have thought you would call from a page template a cfc to return query info on a product and output that. Anything else about this application in particular I should be aware of or wary of duplicating, as maybe there is a better method or better performance to be had another way? _ [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]

RE: Webservice returning CFC in a different directory
In desperation, I've now set up an IIS (...ick...) virtual directory pointing to the directory with all my cfcs in, and lumped the interface cfcs in with the back-end cfcs in the same directory, along with my web service Application.cfm. (ugh.makes my skin feel creepy...). It now works.more or less.some of the time. It seems to randomly fail, giving me errors like cannot resolve CFC datatype for components that have not been changed, the good old cannot generate stub objects error, and a whole host of other axis errors that I'm not even going to bother to list - NOTE: if I restart the server, it works at first, for about 10 minutes, then suddenly stops working for no apparent reason. Oh yes, and if I type in the wsdl address, sometimes I get valid wsdl, sometimes I get nothing but a blank browser screen, sometimes I get an axis error, sometimes I get what looks like valid wsdl but when I try my test client to actually invoke the webservice, it tells me that the wsdl cannot be parsed. Sometimes this happens after I add a totally innocuous line into my web service CFC (like a comment! Yes, adding a comment can break it!), sometimes it starts failing without me changing anything. If anyone can come out with a I've done this and it worked first time, and I've never had any problems with it... I'll be eternally grateful if they can walk me through it. Otherwise, I'm giving up - this is way too much of a headache. Thanks for your help guys.

Webservice returning CFC in a different directory
Morning all I've been tearing my hair out with this one: I have a complex application with lots of CFCs that we want to web-service. The CFCs are in a directory outside the webroot, with a mapping set up to it : call it /mycomponents/ I have a directory /ws/ under the webroot with it's own Application.cfm, where I've put the webservice interface CFCs If I put a noddy method into a webservice CFC, like: cfcomponent displayname=myWebService cffunction name=sayHello access=remote returntype=string cfargument name=myName type=string required=true / cfreturn Hello #arguments.myName# / /cffunction /cfcomponent Then I can view the wsdl and call the method, with no problems The trouble comes when I want to return one of the CFCs from the main application, under /mycomponents/ cfcomponent displayname=myWebService cffunction name=getPersonByID access=remote returntype=mycomponents.person cfargument name=intPersonID type=numeric required=true / cfscript objPerson = CreateObject( component, mycomponents/person ); objPerson.init(); objReturnPerson = objPerson.getPersonByID( arguments.intPersonID ); /cfscript cfreturn objReturnPerson / /cffunction /cfcomponent I get an Axis fault : coldfusion.xml.rpc.SkeletonClassLoader$UnresolvedCFCDataTypeException : Could not resolve CFC datatype mycomponents.person I've tried many different ways of referring to mycomponents/person.cfc in the returntype, none of them work. There's a macromedia technote describing a similar fault to this, when instantiating components as local variables in webservice CFCs, the workaround is to put a mapping into jrun-web.xml I've tried that, and it doesn't work for me. If I copy the person.cfc into the same directory as the webservice CFC, it works OK, but I don't want to have to put the webservice CFCs in the same directory as the back-end CFCs, for various reasons that I won't bore you with. I've spent about two hours googling looking for a solution, and all I can find is people having the same problem. No-one seems to have found a fix. So has anyone got any ideas that they'd like to share?

RE: Webservice returning CFC in a different directory
Hi Mike, Yes, I have a mapping set up to mycomponents. I can create an instance of the CFC in the web service method, no problem. If I do: cfcomponent displayname=Person Web Service Component cffunction name=viewPerson returntype=string access=remote cfargument name=intItemID type=numeric required=true / cfscript objPerson = CreateObject( component, mycomponents/person ); objPerson.init(); objPerson = objPerson.viewPersonByID( arguments.intItemID ); //return objPerson; /cfscript cfreturn personid #arguments.intItemID# / /cffunction /cfcomponent Then it works fine, no errors, and returns the string. But if I uncomment the return objPerson line and change the returntype to mycomponents.person, or mycomponents/person, or /mycomponents/person, or anything similar, I get the the UnresolvedCFCDatatype exception. - Do you have a CF Mapping setup pointing to mycomponents/ ?

RE: Webservice returning CFC in a different directory
Yes, it works if I set the returntype as struct rather than a specific CFC type.

RE: Apache and CF
... the point being (when taken in context with the rest of this paragraph), so many people complain that IIS is rubbish etc etc etc. but that is 90% because they are rubbish etc. etc. etc. and don't actually do any configuration of their server, IIS and so on. ;o) Personally, when I started out with web development back in the arse-end of the twentieth century, I used to love IIS for just the reason Thomas stated - wow, a GUI? Isn't it pretty? And I can look like I know what I'm doing when I really don't But now, after several years of wrestling with web servers, I'm firmly with the IIS is rubbish crowd, from my own painful personal experience. I've had no end of trouble with IIS over the years, from the constant security holes and exploits making it almost a full-time job just to keep the damn thing reasonably safe, to configuration being dropped and sites disappearing for no apparent reason, to the inability to have any confidence in backups, to the fact that it's totally insecure by default and you have to sit down and work at a vanilla install for several hours before anyone with an ounce of knowledge would dare make it public.. etc etc, you get the idea With Apache, all config is done with text files, which means that it can be easily backed-up, altered and re-applied by an automated release process (e.g. an ANT script) or even by a CF script, or rolled back to a previous version if you've made a mistake - and when it goes wrong (which, in my experience, it virtually never has) you can easily look at it and see EXACTLY what the software itself is seeing, in a human-readable format. After a little practice, it's actually pretty easy to debug. Admittedly, I haven't used IIS for a couple of years, so it may have improved a little... Also, if you develop and test on Apache for Windows, you can very easily deploy a site on a UNIX or Windows platform without having to worry about the web server config side of things. Apache is by far the most commonly-used web server out there ( e.g. http://www.securityspace.com/s_survey/data/200405/index.html http://www.securityspace.com/s_survey/data/200405/index.htmlreckons it has a 70% market share across 14 million servers ) and yet how many security alerts do you hear about worms / viruses / DDOS attacks targeting vulnerabilities in Apache? Now how many for IIS?

RE: how to open an attached file in its own application (ms-word, excel etc).. please read
There is no way to do this from a browser (unless you use ActiveX, possibly - I've never tried it) , for very valid security reasons Can you imagine the security risks if it was possible to craft a HTML document that would automatically force-launch a downloaded document in an external application ? No? OK, lemme give you a for instance - I have a word document on my web server In that word document is a VBA macro In that macro is code that sets your IE bookmarks, your homepage, and your Active Desktop to a given url. What if I set that URL to some really nasty hardcore kiddie sado-porn sites? What if I then followed that code with some more code to auto-launch a browser window? What if I then followed that code with some other code to capture the desktop image, and mail it along with a list of your favourites, to fbi.gov, and every other email address I find on your PC? And what if i put some code to auto-download and force-launch that document into one of my web pages? OK, that may be a bit over-convoluted, let's try a simpler example - The way you normally launch a document in a stand-alone application is by executing the application's .exe file with the document title as the first command line parameter. e.g. Start-Run- iexplore.exe http://bcheck.scanit.be/bcheck/sid-9478971b4113f76c5568dc573ea08d34/ What if I ran FORMAT.COM C: /X ?

RE: CFLOCK
The advantage is that you only create them when they're needed. OK, so in that trivial example, there's virtually no difference, but you may have to do some more complicated stuff on application startup. For instance, reading, parsing and initializing language files and variables, if your application is internationalized. Or performing complicated queries for dynamic site configuration that might take seconds to run - you'd then want to cache the results in application scope and duplicate them out. I've done both of these, and when setting up the variables takes minutes but duplicating them out takes milliseconds, it's a real no-brainer. _ From: Pascal Peters [mailto:[EMAIL PROTECTED] Sent: 28 May 2004 09:30 To: CF-Talk Subject: RE: CFLOCK I don't see the advantage over setting them in the request scope directly.

RE: CSV File Format Specification
Hi Brook, There isn't really a proper standard for CSV files, it's not like a JPEG or MP3 or anything. But, having said that, I've never seen a CSV file with text-qualified fieldnames. And the text qualifier should only be used on text-format fields - unless the ID maps to a DB field that is in a text format, you don't need the quotes around it.

RE: Mach-II
Just to stick in my two pennorth, this is something of a pet subject of mine. I wrote an recent article on a similar theme at http://www.headshift.com/archives/001379.cfm There's been some good points on this discussion - I guess my take on it would be that if your planning stage doesn't include which methodology is most appropriate IN THIS CASE?, then that's insufficient planning, full stop. (or period, for the Americans ;P ) And your consideration of which methodology is most appropriate must also include - current in-house expertise - learning curve for a new methodology vs. time constraints for project delivery aswell as the likelihood of future enhancements on this project, etc etc e.g. If you have a shop full of hardcore CFObjects coders, there's no point saying let's do this job in Fusebox 4 / Mach II / methodology X if the deadline is tight. I've been using fusebox since 1999, and I think it's great for MOST apps that I've worked on. On the other hand, I've worked on some projects that have been done entirely in fusebox, but STILL been a nightmare because of insufficient planning. In my experience, the more complicated the application, the more disciplined you should be about sticking to your chosen methodology, whatever it is. I'm sure we've all had some rush jobs that we've thought ah, never mind the full architecture process (or whatever), I'll just hack this together quickly Pretty much every single one of those quick hacks has later turned round and bitten me in the arse to some extent. Have I used Mach II ? Yes Will I use it in future ? Yes, certainly, but with a couple of reservations. Like any new way of doing things, it'll take some time to evolve and mature. Fusebox 1 and 2 were fine for their time, but people (myself include) quickly came up against the limitations of it for more complex projects. Several sites would have been much easier if XFB had been around at the time they were written. Likewise, a couple of big XFB sites I did would have turned out much more elegant if FB3 have been around. I can see similar situations with Mach-II now, and I'm sure when the NEXT version of Mach-II arrives, we'll say the same about apps written in Mach-II version 1. You live and learn.

RE: sql question
Or how about doing it as an inner join - generally more efficient
Select
TP.acctNo,
TP.trxAmt AS posAmt,
TP.trxID AS posTrxID,
TN.trxID AS negTrxID,
TN.trxAmt AS negAmt,
FROM transactions TP INNER JOIN transactions TN
ON TP.trxType = TN.trxType
AND TP.acctNo = TN.acctNo
WHERE TP.trxAmt = 0 - TN.trxAmt
It's also generally considered better coding practice to use JOIN
statements where you can, as it lets you separate the join conditions
from the selection criteria. This helps make the query more readable,
and unltimately more maintainable.

testy this one is i tell ya, testy...
ok. i have a table, with 4 columns:
1. acctNo
2. trxAmt
3. trxType
4. trxId
where trxType might be [d] or [r]
and for every [r] there is a matching
[d]. i want to get acctNo's that match
but only when the trxAmt are opposing
value matches...
could be...
acctNo: 100
trxAmt: -545.00
trxType: r
trxId: 500
and the matching one would look like
acctNo: 100
trxAmt: 545.00
trxType: r
trxId: 510
basically a reversal of a mistaken transaction
now, the problem lies in the fact that there may
be another transaction that matches the acctNo
but has nothing to do with this payment reversal.
can this be done?
here is what i have, and its giving me ones that
match the acctNo, but are extra, since they are not
matching in the dollar value...
select acctNo, trxAmt from transactions
where (trxtype = 'd' or trxType = 'r')
and acctNo in (select acctNo from colthist where trxAmt like '%-%')
group by trxAmt, acctNo
here is a sample set, the first one that pulls up, and clearly
illustrates
the problemo ;)
127-154.50 #1
127154.50 #2
127618.00 #3

133245.00 #12
133500.00 #13
where 1 and 2 are correct but three isnt, and 4,5,6 match 10,11 and
12.
but, i dont want 3,7,8,9 or 13 to be there.
confused, i hope not, but i hope this is possible in a query...

RE: Can anybody see a problem with this?
Hi Bill Off the top of my head I can't think of a reason why that wouldn't work, but to my mind, relying on the server's error catching to perform designed functionality just feels wrong - it feels like bad design, and it's shifting some of your logic from the application itself to the server software that it's running under. Just my opinion, of course, but if it was me, I'd either - - make the default CFM template strip the name of the directory out of the url and check it against the query. - use a url such as http://www.mycompany.com/contacts/BillHenderson , and put an extension-less file called contacts in the root. Make IIS pass files with no extension through CF and put your logic to get the name, check the query and re-locate, into that contacts file. I've used this myself many times on many different webservers, with no problems. Hope that helps!

Hey All - The marketing department of my company wanted to have a list of directories with names of marketing contacts. (http://www.mycompany.com/BillHenderson/, etc) I first set up a tool using cfdirectory and cffile to create the directories and put the files in them. I found that making changes to the files in the directories or adding new directories or deleting the directories caused quite a lot of problems, not to mention the clutter it caused in the root directory of the site, so I came up with this idea, that does not actually use any custom directories at all, and I want to know if anybody can see possible security problems, server resource issues, etc. 1. The user enters the URL in browser with custom directory at the end 2. IIS catches the 404 error and uses a custom cfm template 3. The cfm template pulls the directory out of the url and checks it against a list of names from a cached query 4. If it find a match, it cf_locations to a template with custom content for the marketing contact 5. If no match is found, it cf_locations to the standard 404b.htm from IIS.

RE: CFHTTP documentation.
Hi Wally It's a serial process, I'm afraid. The CFHTTP tag sends out its request and then sits there blocking further execution until it gets a response or times out. The only way round it would be to write a replacement CFX, probably in Java, that was multithreaded.

RE: QuerySim custom tag and Fusebox 3
Hi guys The problem is that thisTag.generatedcontent only captures content that would be destined for the output buffer. If enablecfoutputonly=YES has been called, thisTag.generatedContent is non-existent, unless the tag is called between CFOUTPUT tags. Walk it through - 1) The very first line in the FB3 core file (fbx_fusebox30_CFXX.cfm) sets cfsetting enablecfoutputonly=YES 2) Sections seven and nine of the FB3 core file includes fbx_settings.cfm. enablecfoutputonly is still YES, so any plain text is just ignored 3) Section ten includes fbx_switch.cfm, but does it like this - cfoutputcfinclude template=#FB_.fuseboxpath#fbx_Switch.cfm/cfoutput so THAT's why Cf_querysim works when included from fbx_switch, but not from fbx_settings Workaround - whenever you use a cf_querysim tag, nest it inside a Cfoutput block, like this cf_querysim cfoutput qry_myquery a,column,list your|query|data /cfoutput /cf_querysim or even cfoutput cf_querysim qry_myquery a,column,list your|query|data /cf_querysim /cfoutput Hope that helps, Alistair Alistair Davidson Application Developer Freeserve.com PLC www.smartgroups.com -Original Message- From: Hal Helms [mailto:[EMAIL PROTECTED]] Sent: 26 May 2002 17:07 To: CF-Talk Subject: RE: QuerySim custom tag and Fusebox 3 I just tried it out without problems.

When I use it in a template that I am viewing directly rather than through the Fusebox ( as in /index.cfm?fuseaction=circuit.fuse), it works fine. Also, QuerySim works fine when calling it through the Fusebox, if it is in the home circuit. However, when QuerySim is called in a template used by a child circuit, something wierd happens. I have found that the value of thistag.generatedcontent, which would hold the query contents i pass, is wiped out. Therefore, QuerySim has nothing to make a query out of. I know that the proper place to be using QuerySim is when you're testing individual fuses, especially before you have the real query fuses written, so you can say that i'm using QuerySim improperly anyway by using it within the fusebox itself. (in my defense, i have an acceptable reason to be doing this in this case and its only temporary, but i wont try to explain). Anyway, I thought it was strange that the value thistag.generatedcontent of a custom tag would be wiped out in that way. I have thoroughly tested this and found that, indeed, it only happens when calling it within the Fusebox, and only in a child circuit. I am afraid that this reveals some sort of subtle problem with Fusebox itself! But I am probably (and hopefully) wrong...

Hi, At my last place we swapped all SQL drivers over from ODBC to OLEDB. We didn't really get much of a performance difference, but there was a noticeable increase in stability. I'd say it's definitely worth doing. Just be warned, we did find some niggling syntax differences in some obscure circumstances.

RE: Session variables
OK, here's one example - We have a system where a huge amount of config data needs to be retrieved from a database for each page. Just retrieving all the DB records takes about 2.5 seconds. If you were doing that every page, then you'll very quickly kill just about any server. So what we do is convert those DB records to structres, and store them in the Application scope. On each request, we check if the App structure exists, and if it doesn't (or if a particular parameter is passed in the url) call the code that initialises the structure. Then we duplicate the Application structure into the REQUEST scope, which only takes about 50 ms. how's that? -Original Message- From: Aidan Whitehall [mailto:[EMAIL PROTECTED]] Sent: 09 November 2001 11:31 To: CF-Talk Subject: RE: Session variables There are legitimate uses for the Application scope.

RE: failed retrieval of cached queries
Hi Tim I don't know how much of this response will be relevant to your situation, but here's how we managed to resolve this problem - (apologies if any of this seems patronising, but I don't know what level to aim at here, so I'll explain everything!) We had this problem, and it was driving us absolutely nuts for months. Yeah, sure, some of our old sites (written before any of the current developers had joined the company) had some dubious locking strategies, but the errors kept being thrown on our NEW sites, which used REQUEST variables rather than APPLICATION variables, and had EVERY read/write to a shared scope inside a CFLOCK. After many LNG head-scratching hours, we finally worked out that the following situation could occur - 1) Some old sites were using statements like this - cfquery name=qry_productfeatures datasource=#DSN# cachedwithin=#APPLICATION.querycachetime# 2) Although WRITES to the application variables were cflocked, statements such as the above were not. 3) If that CFQUERY statement was run at exactly the same time as APPLICATION.QueryCacheTime was being set, then the query would still be executed and the resultset cached, but the time for which to hold the resultset in the cache could be corrupt. 4) New sites were also running statements like this cfquery name=qry_productfeatures datasource=#REQUEST.DSN# cachedwithin=#REQUEST.querycachetime# against the same datasource as the old sites, and just occasionally, the SQL might match exactly. 5) The CF engine checks to see if it already has a query called qry_productfeatures on that datasource with the same SQL. If it does, it checks the current time against the cached query's cache time, to see if the query has expired. 6) If the cached query is corrupt, then the cfquery... statement does NOT return an catchable exception - the CF server keeps trying to retrieve it, and eventually (after about 60 seconds, in our case) it gives up, and the CF sub-system throws an error WITHOUT returning execution to your template. 7) For all the time that the engine is trying to retrieve that query, the thread used to process that request is unresponsive. It does NOT timeout at the Timeout request at X seconds setting in the CF administrator. 8) If this is on a frequently hit page, it can very easily clog up the whole thread pool, and leave your CF server unresponsive. 9) The only way to free up the threads again is to bounce the CF service. Conclusions --- 1) DON'T use application variables if you don't have to! Use the Request scope instead. 2) If you HAVE to use application variables (e.g. to store complex persistent structures that are based on huge DB queries that take ages to run), then Duplicate() the application structure into the REQUEST scope in your application.cfm, like this - cflock name=(some name) timeout=2 throwontimeout=YES cfset REQUEST = Duplicate( APPLICATION ) /cflock 3) Make sure ANY references to shared scopes are inside a lock of the same name (or scope) as the writes to those variables. Enforce this on a CODE level- don't rely on the Automatic locking setting in CFAdmin, because this only checks cfset ... statements, and DOES NOT catch implied reads like the cfquery ...cachedwithin=#APPLICATION.QueryCacheTime# statement.

RE: WDDX and structures
John, To encode (serialize) a structure into WDDX - CFWDDX action=CFML2WDDX input=#MyStructure# output=MyWDDXPacket will create a string called MyWDDXPacket with the WDDX encoding of MyStructure. To get it back (de-serialize) - CFWDDX action=WDDX2CFML input=#myWDDXPacket# output=MyNewStructure will create a structure called MyNewStructure that should be an EXACT duplication of the original variable. You can then loop round the structure and convert it's keys into simple values like this - cfloop collection=#myNewStructure# item=key cfset #key# = myNewStructure[key] /cfloop So if your structure was SESSION -category -id -name -number -personalized -price -qty -weight -session id you'll then get simple values (un-scoped) called category id name number personalized price qty weight session id hope that helps Alistair Davidson Senior Developer Rocom New Media www.rocomx.net There is no spoon -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: 24 September 2001 15:12 To: CF-Talk Subject: WDDX and structures Hello all, My first post to the group - hopefully not asking questions that will send eyes rolling. Situation: I'm trying to pass a structure of items from an application to the secure portion of the site to complete checkout/ordering process. The main site sits at http://www.foo.com and the secure portion is on the same server but at a different domain http://secure.isp.com/foo - obviously, session variables won't exist from one site to the next so I'm looking at options for passing the shopping cart structure and a session id#. I could write to a temporary database prior to leaving www.foo.com, then querying said database and re-initializing the needed variables on secure.isp.com/foo but I'm wondering if that's the best approach. Research brought me to the doorstep of WDDX (cfwddx) and it seems like that it *should* work ideally for avoiding database write/reads. Great! Problem: I've been exploring code snippets and examples for just how to achieve the results and I'm stumped - I've had some luck in creating the WDDX packet and can output it's contents for testing using htmleditformat() but I can't figure out how to actually loop through the packet and breakout the variables for use on the secure portion of the site. Questions: 1. Is using WDDX the better approach for accomplishing my task or should I give up and just write to the db? 2. Is anyone doing what I'm attempting and, if so, could you demonstrate how your code works for me? Please? 3. Is there another approach that I should be aware of instead? Add'l info: * I've RTFM - and site after site, post after post still grasping... * The packet is only needed one-way (from main site to secure) and will be discarded after pulling out the variables for secure processing. I don't know if that makes any diff or not * There is a total of 9 variables that exist in the session structure: category id name number personalized price qty weight session id# * Each variable can/will contain several items (except for session id#): id: 23, 356, 698 name: foo1, foo2, foo3 etc... * I'd provide code that I'm using but there really isn't anything more than just some test code at this point.

RE: SQL question about JOIN
Chad, These two queries are NOT doing the same thing! In your second query, the FROM statement and WHERE clause FROM JOBINFO, ACTIVITYLOG WHERE JOBINFO.JOBNUM = ACTIVITYLOG.JOBNUM imply an INNER JOIN, not a LEFT OUTER JOIN. This will only select rows from either table where the JOBNUM field on both tables match, which is an INNER JOIN. In your first query, the section FROM JOBINFO LEFT OUTER JOIN ACTIVITYLOG ON JOBINFO.JOBNUM = ACTIVITYLOG.JOBNUM will return ALL records from JOBINFO, and for each of those records, it will also return all records from ACTIVITYLOG where the JOBNUM field matches. Any records on JOBINFO that DON'T have a matching record in ACTIVITYLOG will still be returned, but the query row for that record will have NULLs in all fields that come from ACTIVITYLOG. That's why the LEFT OUTER JOIN query is taking longer. You should always use explicit join statements in queries for three reasons - 1) It makes the most of the DB engine's query optimiser - I inherited an old site where all queries used the implied join, as in your second query. Just going through and changing them all to explicit join statements cut the execution time by (on average) 50%. 2) You can force join types to make the best use of memory/cpu resources (at least on SQL server, anyway). Sometimes, really complicated queries can be sped up by huge amounts, just by explicitly specifying a HASH JOIN. 3) It's much clearer syntax, and it allows you to separate the JOIN conditions from the selection conditions - example: SELECT Products.Description, Brands.Name AS BrandName, Categories.Title AS CategoryTitle FROM products INNER JOIN Brands ON Brands.Code = Products.BrandCode INNER JOIN Categories ON Categories.Code = Products.CategoryCode WHERE products.description LIKE '%#search_string#%' AND NOT(products.restricted = 1) as compared to: SELECT Products.Description, Brands.Name AS BrandName, Categories.Title AS CategoryTitle FROM products, brand, categories WHERE products.brandcode = brands.code AND products.categorycode = categories.code AND products.description LIKE '%#search_string#%' AND NOT(products.restricted = 1) Hope that helps Alistair Davidson Senior Developer Rocom New Media www.rocomx.net There is no spoon -Original Message- From: Chad Gray [mailto:[EMAIL PROTECTED]] Sent: 18 September 2001 18:45 To: CF-Talk Subject: SQL question about JOIN The first query takes 9seconds to process, the 2second query takes 1seconds to process.

RE: Need your opinion - PLEASE!
There's a common idea amongst database guys that NULLs are evil, but I think that's mainly because they can screw up joins and introduce three-valued logic into queries. For an example, if you have (say) a field called nullfield that contains a NULL value - nullfield 0 will return false. However, NOT( nullfield 0 ) will ALSO return false. It's not greater than zero, but it's not NOT greater than zero either - it's undefined. The only logic statement about it that will return true, is nullfield IS NULL Or if it's a string field - LEN( nullfield ) 0 is false, and so is NOT( LEN( nullfield ) 0 ) again, only nullfield IS NULL will be true. So you have to remember to explicitly account for NULLs in all of your queries and join statements. Apart from that, I don't there's anything inherently 'bad' about nulls, so long as you and anyone who writes queries on the data remember that they may be there and how to deal with them. In my view they can occasionally be very useful, for example, determining when a field has been set to empty, or when it has never been set at all.

Retrieval of cached query failed error
Hi all The saga of our bizarre server errors continues anyone seen (and more importantly, FIXED!) this one before? Retrieval of cached query failed I've scoured the Allaire forums, and the only answers I found were - This error typically happens in one of three cases: 1) If you were trying to insert a query into a full cache where all of the queries were being used you'd get the error. 2) Another place where this could happen is if the cache max size is set to zero and you try to cache a query 3) Finally this occurs when global access to the cache is granted initially, but because the page timeout has been reached the retrieval fails. Well, our server (Win2k, CF4.5.2) has 1.3Gb of RAM, of which only 400Meg or so ever gets used, and we have the maximum number of cached queries set to 1500 (yes, fifteen hundred) so I don't think 1 or 2 are likely. The pages where this is occurring are not slow-running pages, they usually execute in less than a second, and our timeout is set to ten seconds. The server is not even under particularly heavy load - less than 10,000 page impressions a day. Any ideas?

RE: Data Validation
jerry,
how about parseFloat() or parseInt(), depending on whether you only want
integers?
something like
function check_numeric( obj )
{
// parseInt() returns NaN (Not a Number)
// if it can't parse an integer out of the string
if( isNaN( obj.value.parseInt() ) )
{
alert( That is not a number! );
obj.focus();
return false;
}
else
return true;
}
and your input box can check this onblur (when it loses focus) like so -
input name=numberbox type=text .. onblur=check_numeric(this);
or you can check it in the form.onsubmit() -
form .. onsubmit=return(check_numeric( numberbox ));

OT but URGENT - IIS
Hi guys ( gals) Sorry for the OT post, but I REALLY need help on this one, developer's jobs are on the line. We have a serious problem with stability on IIS 5, Win 2K, CF 4.5.2. IIS has suddenly started to die. Symptoms include - - Existing virtual directories get lost. VDir's that have been working fine for 6 months suddenly return This page cannot be displayed IIS errors. If you delete the VDir and recreate it, it works again. - CF pages take forever to return. Flat HTML pages are responding reasonably well, but all the images now take forever to download. Restarting the CF service seems to help, but only for about half an hour, then it returns. - FTP transfer rates have gone down from over 200K / second to about 5 BYTES / second. My first thought was a runaway CF process somewhere, but when we look at performance monitor on the CF/IIS server, CPU usage is only at 5% and memory usage is minimal. Then we thought it might be persistent database locks, but we've eliminated that. Performance monitor on the DB server shows only minimal CPU / memory usage too. We have CF and IIS on one server (Dual PIII 800, 1.3GB RAM) and SQL running on another. The SQL server is set up as the domain controller. CFSTAT shows that the database response time is fine. Performance tracking code in the applications show that CF is running the pages slower than usual, but a page that takes 1.5seconds to execute server-side is taking over thirty seconds to return to the client. I know that at my last job, IIS was rebuilt as a regular maintenance task every two or three months. This installation of IIS has been for the last five or six months until this last week. And no code has changed in the last three weeks. Has anyone else had similar problems? How often do you all have to rebuild / re-install IIS ?

RE: CFLOCK viability?
YOu might be better to do something like this - !--- Application.cfm --- cflock type=exclusive !--- Create your application variables here --- /cflock !--- CHEAT by copying the application structure --- !--- into a local struct that you can read from as --- !--- much as you want --- cflock type=readonly ... cfset theAPPLICATION = Duplicate( Application ) /cflock That way you lock the minimum amount of code for the minimum amount of time, and you're free to read from that local struct without having to worry about locking.

RE: Request vs application scope
That's the downside! Also, they are unique to each request, so memory processor usage will increase by a set amount for each page request. e.g. APPLICATION scope cflock scope=APPLICATION . cfif NOT IsDefined( APPLICATION.TestVar ) !--- Set up (say) 2KB of application variables --- /cfif /cflock - First request, you get a CPU performance hit while you set up the app. variables, and 2KB of memory is taken up by the variables. - Subsequent requests will detect the existence of APPLICATION.TestVar, and not bother setting the variables up again. - Total memory usage - 2KB for the application variables, however many page requests are made. REQUEST scope - cfset REQUEST.(whatever) = (whatever) !--- set up the same 2KB of variables in the request scope --- - Every single request will use the CPU while setting up the variables, and need the 2KB of memory for itself. - If you're in a frameset, that's (say) 3 times the CPU usage and an extra 4KB of memory per client, per hit. - Total memory usage - 2KB * number of frames * number of simultaneous users.

RE: Request vs application scope
Depends on a lot of things - complexity of variables, how often they're going to change, how many users you're expecting, how performance-critical the app is, how long it takes to obtain the values that you're going to store (e.g. if you're storing, say, a five-value array, but populating that array takes twenty queries), etc. etc. etc. Both are valid ways of doing it, I just always try to design data structures in terms of what feels right, for instance, the Home directory of a site feels more like a property of the application, rather than an individual page request, so it goes in the application scope. Besides, if you use app. scope to begin with, you've then got expansibility built in for that horrible day whwn the client says Great, that's just what I asked for, but what I actually WANT is.. -Original Message- From: Daniel Lancelot [mailto:[EMAIL PROTECTED]] Sent: 29 May 2001 15:37 To: CF-Talk Subject: RE: Request vs application scope But using request vars means the memory is released immediately the request has finished...

MopeI tried this Nick but it kept complaining at the ParseInt line
saying object required. I can't see why it shouldn't work as the object
definitely exists. I'm sure I've made a blindingly silly mistake so I'll
persue with it after lunch :)

Does this work?
function test(controlnum) {
elt = document.forms[0][interest + interest];
elt.value = parseInt(elt.value) + 1;
}

I'm having a mind blankarghhh. I'm trying to incremtnet the value of a
control in a form by one where part of the controls name is poassed in as a
variable. Probably best I explain with the code snippet:
function test(controlnum) {
document.forms[0].interest + interest + .value =
eval(document.forms[0].interest + interest + .value) + 1;
}
I have tested using alert and the The RHS of the equation is computed
correctly. I need to let javasript know that the LHS of the equation is an
object in the page rather than just a string but I can't remeber
how!anyone help

RE: Good resource on CF/XML integration?
Yeah, CF_SOXML is an absolutely fantastic tag, I use it all the time for all sorts of things. Well worth downloading and getting into. You should also read up on WDDX - start by looking in the CF Studio help for CFWDDX. Good luck!

I did a quick search on Yahoo and found this. http://www.siteobjects.com/index.cfm?fuseAction=showProducts cf_SOXML version 1.5[r. 01/09/2001] SOXML provides ColdFusion programmers with an easy to use interface for integration of XML with CF. This custom tag is open-source (of course), free, and action based. These actions include: XML2CF (Converts a XML document into a complex CF structure) XML2DOM (Loads the XML document into a valid XML DOM object accessed via CF) XML2HTML (Displays the XML document as IE does but INLINE! very cool for debugging) CF2XML (Transforms any CF variable into a valid XML document) CF2XMLDOM (Transforms any CF variable into a valid XML DOM object accessible with CFML) Transform (Transforms any XML document based on a specified XSL document) I'm sure forta.com and CFDJ would have some info too.

RE: Tertiary Domain Creation
Depends on what server the machine is running. If it's IIS, then look at the admin sample VB scripts -Original Message- From: Karl Simanonok [mailto:[EMAIL PROTECTED]] Sent: 22 May 2001 11:01 To: CF-Talk Subject: Tertiary Domain Creation Some of you who subscribe to Shanje.com's inexpensive web hosting may have noticed how the Web Control Panel allows you to create tertiary domains on domains that you have installed there (for example the tertiary domain karl.simanonok.com is one of the domains under simanonok.com). One nice thing about tertiary domains is that they don't cost anything extra, but they also can make cleaner URLs (karl.simanonok.com is much better than simanonok.com/karl in my opinion). Does anyone know how to create tertiary domains in code so that their generation can be done remotely as in Shanje.com's web control panel? Please don't bother suggesting that I ask the owner of Shanje.com, I've already tried that and he doesn't want to share that knowledge. I'm thinking it might require some kind of Java crapplet or maybe a COM object that ColdFusion can control. Or maybe they reside in the registry and CFREGISTRY is used? Has anyone done this before?

RE: Session Solution.
You could do it with javascript and DHTML, something like this -
cfset TimeoutSecs = 30
div id=Countdown
You will timeout in #TimeoutSecs# seconds
/div
script language=javascript
var Timer = #TimeoutSecs#
window.setTimeout( tick();, 1000 );
function tick()
{
Timer = Timer - 1;
if( Timer 0 )
{
document.all['Countdown'].innerHTML = You will timeout in
+ Timer + seconds;
window.setTimeout( tick();, 1000 );
}
else
{
alert( You have timed out! );
self.location=timeout.cfm;
}
}
/script
It would need a bit of modification to work in Nutscrape, but I hope that
helps!

Subject: Session Solution.
I have been skirting the issue here for a while I am simply trying to notify
a user when their session will timeout. I would like it to count down.
Like a dialog box that says you will timeout in 5 minutes and counts down?
Any ideas?

RE: CF and custom stylesheets
Hi Scott We did exactly the same thing - the trick seemed to be that the style.cfm page has to have a CFCONTENT tag in it, otherwise the browser just doesn't get it. By the way, we found that it killed performance by an incredible amount, so we switched to doing it by writing the stylesheet to a .css file (with CFFILE) once the selections had been made, and just putting link rel=StyleSheet TYPE=text/css HREF=#CSSFilename#.css into subsequent pages. This lowered CPU DB load by almost a third - i'd HIGHLY recommend you try it like this.

I've kinda got this working, but would prefer to improve it a bit. I'm trying to modify an existing app, that uses stylesheets, to allow for customization of the colorsets... so that User #1 can choose the blue set, User #2 the green set, etc. Each set has a hex color code for each of the styles used, stored in the DB... so basically, user logs in, tap the DB for the colorcodes, make session vars out of each, reference said vars when executing the style code, voila - purdy colors. :) I can do this easily enough if I just include the style page (as a .cfm file) - but what I'd *really* like to do is be able to link to the stylesheet page, so that the styles themselves don't show up in the source, i.e. LINK REL=StyleSheet TYPE=text/css HREF=style.cfm I've had some hassles trying to link the page like this... it doesn't seem to properly execute the CF code within. Anyone out there tried to do this same thing, and succeeded? Input would be most welcome. Thanks in advance- --Scott ~~ Structure your ColdFusion code with Fusebox.

You could have the server page that creates the text files - 1) use CFCONTENT to automatically deliver the text files, 2) make it POST the files back with CFHTTP 3) CFOUTPUT the contents of the text file into a HTML comment, then parse the file content out of CFHTTP.Filecontent All of the above are strategies I've used before.
