Re: A neat valueList() trick....
Just a cautionary word: that works wonderfully for straight output, but if you were to do say a listFind() on the altered list, CF wouldn't find the item you were searching for unless you prepended it with a space (e.g. listFind(myList, ' myString') ). But for output, it certainly is a whole lot more readable. :-) Matt I like using valuelist(), but it messes up the display because it crunches the list items together, no spaces after the comma. So I tried this and it worked. Had no idea... cfset voicingList = ValueList(getVoicings.voicingname, , ) Just thought I'd post it in case anyone else ran into the same problem.

Re: lil flash form trick
all good points Bryan :) but not quite sliced bread lol One of the things I have liked about flash and using it for forms was the easy masking and really not letting things be submitted without it being properly formated and now the flash forms make that so simple. Not to mention so much cleaner, you don't got this java mess all over. There are good but not magic we still have to do the logic to get them the right format (depending on location) and I wasn't going there just showing the mask deal cause it seems as though its not in the docs or hard to find so a lot of ppl don't know its there yet.

Re: lil flash form trick
Quite so Bryan! For those who don't know I'm in Australia, and I tried to buy a product on line from a HP subsidiary a few years ago - a large, reasonably well managed international company - and I was required to enter my 5 digit zip code (we only have 4 digits here, and anyway, it validated against a list of US zip codes), my phone number in US format ( we dont have (xxx) yyy- format here - it's (x)-) and of all things, my SOCIAL SECURITY NUMBER!!! I dont have a social security number, because I'm not in the USA. I ended up having to call my brother who lives in Indianapolis, and ask him for his, and make up a number similar to that. HP ended up getting my order, because i really needed the product, but their info was useless because it had a bogus zip code, a non-existent phone number, and a fraudulent social security number. If I hadn't needed the product so badly, I'd never have bothered with the order. Although maybe not. I was so intrigued with how flawed the form design was, it became a challenge for me. Maybe I'd have persevered after all.

RE: Is there a trick...
Think of frames as individual pages. Including not only the page that creates the frame, but each frame's SRC attribute. Therefore each has its own set of request variables that have to be handled in the same way that individual pages have to handle them. Once you get this, then dealing with frames is neither more nor less difficult than any regular page -- although, to be sure, a frames-based site will typically score much much lower in the search engine rankings than the equivalent non-frames site. -Original Message- From: Che Vilnonis [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 01, 2003 5:02 PM To: CF-Talk Subject: Is there a trick...

While a CF Template can generate and output an html document which contains html elements with SRC attributes (frames,iframes,images,script libraries and style sheets, any of which may be a coldfusion template), the html elements which include these extra files require an additional http request from the browser and are not actually a part of the parent template request (the cf template containing the frameset for instance). That being said, your frames page looks like this: FRAMESET.CFM cf_stuff frameset ... frame name=blah src=blah.cfm frame name=blah2 src=blah2.cfm /frameset So if you call http://www.mydomain.com/frameset.cfm frameset.cfm is a request that includes Application.cfm and OnRequestEnd.cfm (if available) and then the same is also true of blah.cfm and blah2.cfm which are each their own requests. So if you need to copy data down from the application scope into the request scope so that it's available in blah.cfm and blah2.cfm you have to do that within each of those requests. If you use an Application.cfm for this purpose, then you can allow the one reference to handle all requests for you without having to copy and paste or include the code on every page.

No actually each of the frames are independent web pages so the request variables do not pass through to them. For example, technically (if not legally) you can create a frameset with http://www.macromedia.com/ as one of the frames. The Macromedia.com page won't receive your request variables. -Original Message- From: E.

Re: Is there a trick...
Isaac, What's the benefit that CFMX offers in the Application scope? Calvin There were issues involving using unlocked shared scope variables prior to CFMX asside from race conditions (data corruption in memory). In MX locking only needs to be done on shared scope variables for the purpose of handling race conditions, so you don't have to worry so much about making sure that every access of an application scope variable is locked. I still use locking routines in my applications which cover both race conditions and ensure that all shared scope variables are locked, partly for backward compatibility and partly because hosting providers have the ability (although very very few do) to require locking of shared scope variables via the CF administrator. As a matter of fact, here are a couple templates I use to access shared scope vars (sorry for the line wrap guys). This template allows me to access all my shared scopes and know they're properly locked without having to continually write out cflock. It also handles all the associative array (structure) syntax so that I can simply pass a dot-delimited string and know that it will set or get the appropriate value even if the string contains hyphens and other non-variablename safe characters. SYNTAX: to check for the existance of and set default for an application variable you would use something like this: cf_cache action=get variable=[EMAIL PROTECTED] default=#arraynew(2)# return=myarray CACHE.CFM cfsilent cfparam name=attributes.action type=string cfparam name=attributes.variable type=string cfparam name=attributes.scope type=string default=CALLER cfparam name=attributes.return type=string default=tObject cfparam name=attributes.timeout type=numeric default=30 cfset attributes.variable = listtoarray(attributes.variable,.) cfif not listfind(session,server,application,attributes.variable[1]) cfset arrayprepend(attributes.variable,application)/cfif cfset attributes.cachescope = attributes.variable[1] cfset attributes.varlen = arraylen(attributes.variable) cfswitch expression=#attributes.action# cfcase value=get cfset variables.self = false cflock scope=#attributes.cachescope# type=readonly timeout=#attributes.timeout# cfset variables.scope = evaluate(attributes.cachescope) cfloop index=x from=2 to=#attributes.varlen# cfif not isstruct(variables.scope) or not structkeyexists(variables.scope,attributes.variable[x])cfbreak/cfif cfset variables.scope = structfind(variables.scope,attributes.variable[x]) cfif x is attributes.varlencfset variables.self = duplicate(variables.scope)/cfif /cfloop /cflock cfif isboolean(variables.self) and variables.self is false and structkeyexists(attributes,default) cfset variables.self = attributes.default cfmodule template=cache.cfm action=set objectdata=#attributes.default# variable=#arraytolist(attributes.variable,'.')# /cfif cfset variables.returnvar = variables.self cfinclude template=return.cfm /cfcase cfcase value=set cfparam name=attributes.objectdata cfparam name=attributes.timestamp type=boolean default=true cfif attributes.timestamp and isstruct(attributes.objectdata) cfset attributes.objectdata.tapstoragetime = now()/cfif cfset variables.objectdata = duplicate(attributes.objectdata) cfset variables.element = attributes.variable[attributes.varlen] cflock scope=#attributes.cachescope# type=EXCLUSIVE timeout=#attributes.timeout# cfset variables.scope = evaluate(attributes.cachescope) cfloop index=x from=2 to=#decrementvalue(attributes.varlen)# cfif not structkeyexists(variables.scope,attributes.variable[x]) cfset structinsert(variables.scope,attributes.variable[x],structnew(), true)/cfif cfset variables.scope = structfind(variables.scope,attributes.variable[x]) /cfloop cfset structinsert(variables.scope,attributes.variable[attributes.varle
RE: Is there a trick...
Pretty sure. The docs: While the ColdFusion Server is thread-safe and does not try to modify a variable simultaneously, it does not ensure the correct order of access to information. If multiple pages, or multiple invocations of a page, attempt to write data simultaneously, or read and write it at the same time, the resulting data can be inconsistent, as illustrated in the following Sample locking scenarios section. It doesn't say thread-safe except if you try to access application and server scopes. Yes you still have to lock them. But CFMX does it automatically, so you don't have to do it explicitly. -Original Message- From: Barney Boisvert [mailto:[EMAIL PROTECTED] Sent: Wednesday, 2 April 2003 11:17 a.m. To: CF-Talk Subject: RE: Is there a trick...

RE: Is there a trick...
Are you sure about this? It is my understanding that the session scope was protected automatically, but that the application (and server) scope still had to be locked. You can avoid having to do read locks with CFLOCK on a scope if you ensure that they are never written after initially set, and that every request ensures that they are set before proceeding, but you still have to lock them in one form or another. This is no longer the case in CFMX, exactly. That is, the server won't crash if you don't lock persistent memory variables, as it very well might with previous versions. However, you may still have logical errors (incorrect values, essentially) if you don't lock persistent memory variables, just as you might have in a multi-user database without locking. This is true for all persistent memory scopes in CFMX - Session, Application and Server.

RE: Is there a trick...
I'm guessing that they actually mean if your variables get hozed as a result of not locking it's happening because of a race condition of your own making. Rather than data in the shared scopes may be randomly corrupted if not locked. For instance -- if you have a frameset that loads 2 frames and you need to set an application or session var before frame2 loads, but you set it in the template loading in frame1 there's a chance it might not get set until after frame2 loads and thereby frame2 would contain the wrong data -- but not through any fault of the server. This is probably a poor example, but at the moment it's the best I can do. :) I interpret that paragraph as The app server won't dump core if you don't lock your shared access, but your variable might get hosed.

Whether the server protects it's own memory or not isn't a big deal, it's whether the values in memory are valid. This is true -- although the situation with MX is the same situation faced by all programming languages. Race conditions are universal. So in the context of what's the advantage of application vars in MX that's why I say, you don't necessarily have to hound your shared scope variable with locking the way you did with CF 5 because in CF 5 and prior improperly locked variables had a way of being randomly corrupted so you'd wind up on sites with any reasonable traffic load where some user would have data from another guy's session, etc... But asside from that simply using a shared scope variable doesn't necessarily mean that you will have a race condition that will need to be locked against. For instance, if you set a session variable when a user logs in and then remove that session var when they log out, and in no other place in the app is that var modified in any way, then that var will likely never experience a race condition. But in CF5 and prior you still had to lock it anyway just because it's a session var. --- Barney Boisvert, Senior Development Engineer AudienceCentral (formerly PIER System, Inc.)

Pretty sure. The docs: While the ColdFusion Server is thread-safe and does not try to modify a variable simultaneously, it does not ensure the correct order of access to information. If multiple pages, or multiple invocations of a page, attempt to write data simultaneously, or read and write it at the same time, the resulting data can be inconsistent, as illustrated in the following Sample locking scenarios section. It doesn't say thread-safe except if you try to access application and server scopes. Yes you still have to lock them.

Are you sure about this? It is my understanding that the session scope was protected automatically, but that the application (and server) scope still had to be locked. You can avoid having to do read locks with CFLOCK on a scope if you ensure that they are never written after initially set, and that every request ensures that they are set before proceeding, but you still have to lock them in one form or another barneyb --- Barney Boisvert, Senior Development Engineer AudienceCentral (formerly PIER System, Inc.)

RE: MX and URL trick for search engines
IIS gives a 404 error, and fails to hand off the page to CFMX for processing. It isn't a CFMX error for an unrecognized variable. Therefore, I don't think there is any code we can put in our CFM pages to solve this. A lot of people use this trick, especially on apache with 'mod_rewrite'. The commercial ISAPI filter is IIS Rewrite from http://www.qwerksoft.com/. Still researching...

yes. update tableA set fieldA = 1 since YOU are updateing the table you already know what the value will be. Of course, you could clarify your question.

In this particular case, if you're using IE, you can just choose "VIEW

anyone who could do anything useful with their HTML wouldn't be stopped by
this silliness.

Its not the front page click onto one of their links to another page. The
give it a try. its just javascript that keeps the event onmousedown from
