RE: Releasing client to do another process?
This is actually very simple, 1: Create a page, and within create an iframe 100% high and wide. Call, parent.doSomething() from the iframe to call the _javascript_ function in the page where the iframe is. This does not complete the process if the user closes the window! Only if it browses to another place. 2: Create a scheduled task, and run this task immediately. When the task is finished remove it. This task is not dependant on the browser window clientside. If you need session vars etc. in your task, pass them to the task as parameters, or find a way to overcome this.

CFCs - more smaller or fewer bigger ones?
I am laying out the CFCs I need for a new site, and wondered if there was a 'best practice' for the way to assign the methods to CFCs. For example when I think about users for the site,there are a number of methods I needrelated to logging in and logging out, maintaining user details, sending e-newsletters, listing users.Is there any advantage or disadvantage to having all those functions in one 'Users cfc or is it better to have smaller, more specialised CFCs.Perhaps in this example a UserMaintenance CFC and another UserLogin CFC? I understand about the re-use opportunities, so I think methods related to this site alone should be on their own, but in general terms, is it better to have fewer, larger CFCs or more but smaller and more specialised ones?

Tuning DB connections?

Advice for CF Query and Schema
I am trying to design two databases that share a relationship that contains information for online training courses. So in the first table courseoutline they would use a html form to add the course information to the db such as ID = 1 Course Title =i.e. Windows 2000 Course Summary = Summary of Course in this field Owner = automatically populated through session name variables. Coursepath - contains word doc containing course contents uploaded via cffile In the second table iteccourse they would use a form to add the course dates and availability to the db such as CourseID = 1 Course Title = Selected from form select field populated using CFwith entries from the course title field in the courseoutline db. Coursedate = 17 July 2004 Duration = 3 Days Availability = Yes/ Full Owner = automatically populated through session name variables. Then in the detail page of the training site what coldfusion query would be needed so that if I just wanted to view upcoming Windows 2000 courses it would bring back the related coursepath for that course?? Any ideas on the best way to achieve this - or could my table schema be improved ??

Re: StructKeyExists() vs IsDefined()
Sean Corfield wrote: isDefined() uses the standard CF scope lookup rules that have been around for a long, long time. Yes, but the one of the reasons used to in persuading people to scope their variables properly other than good practice was so that isDefined() only checked a specific variable in a specific scope, not every possible conotation of that variable and scope.This is something that was touted a long long time ago, before I remember your good self being around. Knowing that as CTO you will know better than me the inner workings of CF, are you saying that CFMX does not do this? and in general when you scope a variable, you know the variable exists in that scope. Thats just not true.There will always be situation where variables do not exist.Its simply not practicable or sensible to define every single variable that an application will ever use at any point in its entire lifetime, plus there are 3 scopes that you cannot and must not assume existance of your application's required variables.The easiest way to tell ifthe user has been this way before is to check to see if required, persistent variables are already in existance. In fact, come to think of it, there are only 2 scopes that you can safely assume exist in the first line of your code. These are SERVER and CGI.All other scopes and, therefore, those structures may not exist. This would means that scoping is not really taken into account by coldfusion, other by pure luck that functions like isDefined() look in the null scope first. Sure, scoping is taken into account - and there is no null scope. I think you misunderstand what I mean by null scope.The lookup rules must be looking at a variable _without a scope_ before it starts looking through the other scopes. This is what I mean by a null scope. Everything lives in a scope. Total aside - I did find in CF5 that a number of the scopes were actually available via the variables scope as well directly through their own scope. I did find this little fact useful on a couple of occasions, though it now escapes me why. The lookup rules are a convenience so that you (mostly) don't have to specify variables. everywhere. Grrr, but that is why I do specify scopes everywhere, unless I slip and get lazy (variables scope only), so that CF does what its told and doesn't decide to trundle off through all the scopes.Maybe I'm still stuck in CF3/4/5 land too much. If isDefined() is not taking scopes into account, does it keep going until its checked all scopes or does it stop searching when it hits the first occurance? First off, it *is* taking scopes into account - according to the variable lookup rules - See comment about null scopes to realise that, no, it is not taking scopes into account, only *appearing* to take scopes into account. If it was taking scopes into account, then it would check variables.myvariable and stop, not trundle through all the scopes looking for variables.variables.myvariable, form.variables.myvariable, etc and secondly, yes, it stops as soon as it finds a defined path to a variable. That's why I said the difference is only visible for *un*defined variables (or where a variable is defined in a scope other than the 'closest' scope). Thought it was - I was just being inflammatory... (I think thats the right word) Sorry... one of those days... cfif IsDefined(variables) AND StructKeyExists(variables.variables,test) That's wrong on two levels: 1. variables is *always* defined because it is a scope 2. if variables.variables doesn't exist you'll get an exception! ok - the whole using a variable called variables was just way too confusing, but I was trying to follow on with the examples that had previously been given and it all got a bit out of hand. No, that's the whole point - you *don't* need to use isDefined() because you *know* the built-in scopes exist. So are you saying that every scope all ready exists in CFMX as a structure, even if that scope is empty? Does this hold true for previous versions of CF?I'm still mostly on CF5. Don't fix what ain't broke, particularly if the client is happy. I understand what is happening here, but it means that variables.foo.bar doesn't exist either, that foo.bar can only be referenced by variables['foo.bar'] and CF is letting people create variables with invalid characters in their names. CF has always allowed variables with . in them. In fact that was one of the specific differences between CF5 and CFMX: CF5: cfset foo.bar = 42 Creates a variable called foo.bar CFMX: cfset foo.bar = 42 Creates a variable called foo as a struct with a key called bar Gah! I hate being on the fence between CF5 and CFMX.My brain does both versions at the same time.I write for CF5, but take into CFMX and vice versa. I can't remember what I can and can't do going back to CF5 sometime! In this case I was thinking specifically of CFMX for exactly the

RE: Tuning DB connections?
It seems to me that there are too many unknowns in your question and 16ms is a very small amount of time to worry about... Is your DB connection from Cold Fusion using OLE DB, ODBC, JDBC etc, is CF on the same server as SQL Server, is Query Analyzer taking into account network response time or is SQL returning the time of execution directly? I'm certainly not sure... If you are running over a network, 16ms is trivial and could be caused by all manner of things including TCP/IP errors/retries, general network load, and a whole heap of other factors. I really don't think you are every going to reduce these sorts of times down when you look at the system as a whole. Comparing Query Analyzer directly against Cold Fusion is fatal. You would be better off writing an ASP or PHP version of the code and comparingthe results you would get from them as the way in which they work is analogous to the way CF works...

When you only have to execute one query on a page then latencies of 16ms are no problem, but this is the case where you have pages with for ex. 10 calls to stored procedure, checking childs, checking access, checking poll results, checking latest news, etc. The sum of all those latencies is at my point 110ms, while each query executes with 0ms in QA. This means ColdFusion Server is adding a latency of 110ms on each request, no mather how fast your server will be. The only thing I can do is putting the results in memory resident variables to speed up the process (either session, application or just a cachedwith timespan) and that is a pitty, especially while we use ColdFusion for Enterprise purposes and not for honkietonkie hobby stuff. :-) Micha Schopman Software Engineer Modern Media, Databankweg 12 M, 3821 ALAmersfoort Tel 033-4535377, Fax 033-4535388 KvK Amersfoort 39081679, Rabo 39.48.05.380 [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]

No change when using the cfstoredproc method. Still the same odd latency changes. With both the cfquery and the cfstoredproc method I saw a 15ms requesttime passing by. This would mean there is no 16ms hartbeat signal. Interesting.

To: CF-Talk [EMAIL PROTECTED] I am laying out the CFCs I need for a new site, and wondered if there was a 'best practice' for the way to assign the methods to CFCs. For example when I think about users for the site,there are a number of methods I needrelated to logging in and logging out, maintaining user details, sending e-newsletters, listing users.Is there any advantage or disadvantage to having all those functions in one 'Users cfc or is it better to have smaller, more specialised CFCs.Perhaps in this example a UserMaintenance CFC and another UserLogin CFC? I understand about the re-use opportunities, so I think methods related to this site alone should be on their own, but in general terms, is it better to have fewer, larger CFCs or more but smaller and more specialised ones?

RE: CFForm, CFInput, etc not xhtml compatible!
Just curious, what's the big advantage of XHTML compatible? That's a good question, I think. Right now, the advantage is minimal if not completely illusory. There aren't any devices out there which take advantage of XHTML specifically, to my knowledge. So, in current browsers, XHTML is functionally identical to HTML for most of us. However, in the future, I expect that XHTML will be very widely supported by all sorts of browsing devices. Because XHTML is an XML language, it can be parsed by any XML parser. XML parsers are a lot smaller (and stricter) than HTML parsers, which typically have all sorts of error handling for malformed HTML. So, XHTML documents can conceivably be used by many devices other than desktop browsers. In addition, it's a lot easier to ensure that your documents aren't malformed or invalid with any XML language, compared to HTML. So, rather than rewriting everything in XHTML later, it makes a lot of sense to use XHTML now, since it works with today's browsers. It's kind of tedious and painful to rewrite existing HTML as XHTML, but it's easy to write new XHTML.

Anyone else notice this? I would hate to have to recode all of my pages when the directive comes down to be xhtml compatible (I know it's coming just don't know when). Yes, this is a known issue with the current version of CFMX. However, based on what has been demonstrated about Blackstone at user groups, I strongly suspect this will be resolved (and then some) in the upcoming version of CF. Beyond that, though, I'd recommend that you use something like qForms, or build your own form validation mechanism, rather than using CFFORM. While it's very easy to use CFFORM, it's a bit harder to customize it to your liking. I strongly recommend you look at qForms.

RE: CFCs - more smaller or fewer bigger ones?
But this means you have to document your CFC's carefully. When you modify a CFC later on, you want to make sure you are not breaking other code in the system, so it is a good behavior to document dependencies of the CFC in a document, so you can easily see CFC 2 and CFC 3 are used by CFC 1. Or even better document it via UML :-) Micha Schopman Software Engineer Modern Media, Databankweg 12 M, 3821 ALAmersfoort Tel 033-4535377, Fax 033-4535388 KvK Amersfoort 39081679, Rabo 39.48.05.380 [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]

You can perform XSLT on xhtml pages... which according to the XSLT cookbook (O'Reilly) for more details on how this is going to be very handy in the future Some examples off the top of my head - XSL template to change specific XHTML elements - Prefilling XHTML forms without server side intervention - Will make future programming tasks easier Of course, if you're using server-side processing, these things aren't especially useful, I suspect.

RE: Tuning DB connections?
When you only have to execute one query on a page then latencies of 16ms are no problem, but this is the case where you have pages with for ex. 10 calls to stored procedure, checking childs, checking access, checking poll results, checking latest news, etc. The sum of all those latencies is at my point 110ms, while each query executes with 0ms in QA. This means ColdFusion Server is adding a latency of 110ms on each request, no mather how fast your server will be. The only thing I can do is putting the results in memory resident variables to speed up the process (either session, application or just a cachedwith timespan) and that is a pitty, especially while we use ColdFusion for Enterprise purposes and not for honkietonkie hobby stuff. You shouldn't be seeing that latency if you're running multiple queries within the same page that use the same database connection. Do you have the maintain database connection option enabled within the datasource settings? Are you using the most recent JDBC drivers from the MM site? As an alternative, you might also try MS's own JDBC driver too.

RE: Tuning DB connections?
This stored procedure is taking 0ms in QA (Also profiler states it has a low cpu hit). It is also taking 0ms in #cfquery.executiontime# ... when it likes to. So I am wondering, what is in the way which could cause such big big performance decrease on some occasions. If it was 0-5 ms, I would say.. well okay could be latency. But in 50% of the cases cfquery.executiontime returns 16ms, and I am wondering why. :-) Unfortunately, CF isn't the most accurate timekeeper. At least with previous versions, there was a margin of error of +/-10 milliseconds.

RE: Tuning DB connections?
Does anyone have good references on tuning DB connections between CF Server and MSSQL 2000? I run a couple of stored procedures and I am noticing that execution times of a specific stored procedure are at one time 0ms and at another time 16ms with exact the same recordset. I also ran the stored procedure in Query Analyzer in it says 0ms for each of the 150 itterations I've done. I want to bring all requests down to 0ms, so I am wondering where that 16ms delay is coming from? It must be between the connection of CF Server and MSSQL 2000. What is weird, is that it is always 16ms, not 1ms or 5ms, but it is either 0ms or 16ms (which is a quite big delay). I am using CF5 Ent. as testing environment. Anyone have good practices on this one? Unfortunately, my earlier response to this was based on the assumption you were using CFMX. I apologize. With CF 5, there isn't all that much you can do to tune the database connection from within CF itself. Make sure that you maintain database connections. I would recommend that you test your queries by running them through another ODBC client from the web server's console. I suspect you'll see the same delay no matter what ODBC client you use.

RE: CFMX is crashing daily with no hints in the log
But still, Macromedia needs to give this issue attention. Microsoft SQL Server doesn't crash either when it does not have enough memory to do it's job (it is even possible to run with 4MB ram). In fact I am a bit astonished because since the first beta versions of ColdFusion, there were problems keeping it stable under load, and still these issues arise. These issues should never arise imo :-) Unfortunately, application servers are always more likely to crash than database servers. In my experience, database servers tend to be very stable and robust. Application servers don't.

Re: StructKeyExists() vs IsDefined()
Yes, but the one of the reasons used to in persuading people to scope their variables properly other than good practice was so that isDefined() only checked a specific variable in a specific scope Not sure who was saying that (as you say it was before my time) but scoping variables is worthwhile in general to control lookup. My recommendation is simply: - don't use isDefined() - always scope your variables Knowing that as CTO you will know better than me the inner workings of CF, are you saying that CFMX does not do this? I'm not CTO (I'm not actually sure who is - it was Jer when he was still around and he was my boss). Anyways, CFMX is backward compatible with this behavior - so the recommendations still apply. Thats just not true.There will always be situation where variables do not exist. But if you know which scope they might / should be in you can always use structKeyExists() and avoid this issue... Grrr, but that is why I do specify scopes everywhere, unless I slip and get lazy (variables scope only), so that CF does what its told and doesn't decide to trundle off through all the scopes.Maybe I'm still stuck in CF3/4/5 land too much. No, that's still good practice for CFMX. Thought it was - I was just being inflammatory... (I think thats the right word) Sorry... one of those days... Not a problem - it's certainly surprising behavior no matter that it can be explained using existing language rules :( So are you saying that every scope all ready exists in CFMX as a structure, even if that scope is empty? Yes. Does this hold true for previous versions of CF?I'm still mostly on CF5. Don't fix what ain't broke, particularly if the client is happy. No, that's one of the big differences: CF5 treated scope names as sort of magic reserved words whereas CFMX treats them as real variables of type struct. I think that CF5 might return false for isDefined() on some of the scope names (haven't tried it... isDefined(server) anyone?). Gah! I hate being on the fence between CF5 and CFMX.My brain does both versions at the same time.I write for CF5, but take into CFMX and vice versa. I can't remember what I can and can't do going back to CF5 sometime! I agree. I started with CFMX but I've had to go back and learn CF5 as well (if only so I can understand the pain expressed on the mailing lists!). What you're saying here is that not only does isDefined() not take into account scopes (as argued above), it also has an added layer where having checked for the structure foo and the key bar in all the scopes and not found it, it now looks for the variablefoo.bar in all the scopes too? Whilst I will disagree with the first part of that, the second part is correct - isDefined() will go looking for foo.bar because - in CF5 - it could have been a valid variable name. Sorry to bang on about this, but isDefined() appears not to be working the way I have, perhaps mistakenly, understood in the past from the various book writing luminaries of the mailing lists. I think this is just a corner case that most people tried to ignore ;) Also as a mainly CF5 developer I have to be sure that isDefined() is doing the right thing and that structKeyExists is _only_ a CFMX short cut. It's true that you can't use structKeyExists() everywhere in CF5 (since not all scopes behaved like structs). The right thing in CF5 is debatable however since CF5 specifically allowed dots in variable names which is why isDefined() has such funky behavior! :) [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]

RE: Tuning DB connections?
I know, ColdFusion never was accurate with timings, not even the beta's, but... in this case timings are returned with a similar pattern in delays which makes me think hey something is holding it. I have also tried some other options ( I know I must be glad with that occasionally 16ms delay ... but still it must be possible to get it better ..:P ), and switch the datasource from a ODBC connection to a OLEDB connection. The OLEDB connection seems to act slower than the ODBC. I have the latest drivers, and the latest mdac. For people just tuning in, the server used is CF5 Ent. Management is to shitty to step to CFMX6.1 so I will try the same app on a CFMX6.1 box later to see the differences. I expect the CFMX6.1 box to be slower in DB access because of the java translation layers NOTE: One reason also, why most people do not like to use cfstoredproc is the lack of caching options. The only reason why I would use cfstoredproc, is to handle multiple returned datasets.

RE: Tuning DB connections?
I expect the CFMX6.1 box to be slower in DB access because of the java translation layers You may be pleasantly surprised, then. There don't appear to be a whole lot of additional translation layers; you don't use ODBC or OLEDB at all with the pure Java JDBC drivers from MM/DataDirect or MS. NOTE: One reason also, why most people do not like to use cfstoredproc is the lack of caching options. The only reason why I would use cfstoredproc, is to handle multiple returned datasets. If you're using MS SQL Server, you can call stored procedures from within CFQUERY and still use CACHEDWITHIN/CACHEDAFTER. Conversely, if you were using passthrough SQL and CFQUERYPARAM within a CFQUERY, you can't cache that either. In general, I'd recommend that you use Session, Application or Server variables to cache recordsets, instead of using CACHEDWITHIN/CACHEDAFTER.

Anyone else notice this? I would hate to have to recode all of my pages when the directive comes down to be xhtml compatible (I know it's coming just don't know when). Yes, this is a known issue with the current version of CFMX. However, based on what has been demonstrated about Blackstone at user groups, I strongly suspect this will be resolved (and then some) in the upcoming version of CF. Beyond that, though, I'd recommend that you use something like qForms, or build your own form validation mechanism, rather than using CFFORM. While it's very easy to use CFFORM, it's a bit harder to customize it to your liking. I strongly recommend you look at qForms.

QofQ and javacast
Hello all, I am seeing a problem when I am running a QofQ union with two cfsearch results. It looks like CF is typing based on the first row of data in the cfsearch query. I need to make CF type a column of the CFsearch query as a varchar rather then a number. I have heard that a javacast may be able to help me out. Can anyone show me how that would be done? cfsearch collection=get_Products name=getSearchResults1 type=explicit criteria=CF_KEY SUBSTRING #trim(form.criteria)# cfsearch collection=get_Products name=getSearchResults2 type=simple criteria=#trim(form.criteria)# cfquery name=getSearchResults dbtype=query Select CUSTOM1,CUSTOM2,RECORDSSEARCHED,SUMMARY,TITLE,URL from getSearchResults1 union Select CUSTOM1,CUSTOM2,RECORDSSEARCHED,SUMMARY,TITLE,URL from getSearchResults2 /cfquery Thanks Mark W.

RE: CFMX and MySQL Text field
Use the built-in toString() function around the column: cfset temp = toString(qryPart.Desc) / This can also happen when you're using MySQL to format something (i.e. a date or number) into a string in the database.ByteArrays can generally be converted to strings, it's just the conversion won't happen automatically, so you have to do it explicitly.

You're looping over that query so try removing market.market and just use market. 195 :cfloop query=market 196 :option value=#market.c_marketid# cfif tmp1 IS market.market selected/cfif#market.market#/option 197 :/cfloop [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]

RE: attribute value...
No.. the table existed since yesterday, I changed the name of the query from market to markets and did this throughout the code from market.c_marketid to markets.c_marketid and market.market to markets.market. This corrected the problem, so I'm happy.
