Re: How do you use UDFs in CF 5
I was looking at cflib.org at the various UDFs that can be downloaded. However, I'm not aware of how you use the UDFs. 1. Do you place them in the root of the site you're working in or the custom tags directory and 2. How do you call and use them as far as within your scripts. I haven't had a chance to check the docs on CF 5 yet, so would appreciate any feedback. Thanks. __ Why Share?

RE: How do you use UDFs in CF 5
1. Do you place them in the root of the site you're working in or the custom tags directory and A UDF must be in the local scope. Think of it like a variable. I can't cfoutput #x# unless I defined it earlier. Now, just like variables, UDFs do not need to be on the same physical page. I can CFINCLUDE a template that contains the UDFs, or define them in the Application.cfm file. 2. How do you call and use them as far as within your scripts. They act just like BIFs, or built in functions. Consider: !--- ArrayLen is a built in func --- cfset foo = arrayLen(x) !--- countIT is a udf cfset foo = countIt(x) === Raymond Camden, Principal Spectra Compliance Engineer for Macromedia Email: [EMAIL PROTECTED] Yahoo IM : morpheus My ally is the Force, and a powerful ally it is. - Yoda __ Get Your Own Dedicated Windows 2000 Server PIII 800 / 256 MB RAM / 40 GB HD / 20 GB MO/XFER Instant Activation · $99/Month · Free Setup http://www.pennyhost.com/redirect.cfm?adcode=coldfusionb FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ Unsubscribe: http://www.houseoffusion.com/index.cfm?sidebar=lists
Re: How do you use UDFs in CF 5
Start by sticking them in the same page you're calling from (just to
get the hang of it):
cfscript
function sayHello (name) {
return 'Hello, ' name;
}
/cfscript
cfoutputsayHello('Joe')/cfoutput
Yields: Hello, Joe
But the best way is to stick all of your UDFs on one page, and include
the file in your application.cfm. Or, you can organize functions into
libraries.

RE: How do you use UDFs in CF 5
When you include lots of UDFs, is there a performance concern? If I
download strLib from cflib.org (which has 81 UDFs), should I delete all
the
UDFs that I don't plan to use?

Loading any large amount of code that you don't plan on actually using would be a bad idea. If you look at the source headers in the libraries at cflib.org you would see us warning you about that. However, I don't think you have to be extremely worried about it. 81 UDFs is quite a lot if you only plan on using a few, so yes, I'd trim that library down to what you need. === Raymond Camden, Principal Spectra Compliance Engineer for Macromedia Email: [EMAIL PROTECTED] Yahoo IM : morpheus My ally is the Force, and a powerful ally it is. - Yoda __ Get Your Own Dedicated Windows 2000 Server PIII 800 / 256 MB RAM / 40 GB HD / 20 GB MO/XFER Instant Activation · $99/Month · Free Setup http://www.pennyhost.com/redirect.cfm?adcode=coldfusionb FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ Unsubscribe: http://www.houseoffusion.com/index.cfm?sidebar=lists
