Title: Truncating Text to the Nearest Whole Word

Summary: Looking for a way to truncate a title that is longer than 150 characters without breaking up a word? Try the FullLeft() UDF available at cflib.org.
 
Title: Cannot Use UDF Inside Custom Tags?
Date: 05/03/04      (19 Posts)
Summary: In CF5, if your custom tag needs an end tag, simply placing a UDF within <CFIF thisTag.executionmode is "start"> will generate an error. To work around, place the UDF in a separate file, CFINCLUDE it at the top of the calling page within <CFIF not isCustomFunction("myFunction")>, and then set the function to a global scope.

<SELECT onchange="this.form.submit();"...>
 
Title: Closing Custom Tags
Date: 05/03/04      (30 Posts)
Summary:

To make your custom tags safe for nesting with CFMODULE syntax, always include an end tag and use the following code to prevent the tag from executing twice:

<!--- This tag does nothing in end mode --->
<cfif ThisTag.ExecutionMode eq "END">
<cfexit method="EXITTAG">
</cfif>
