Is this what you mean (the cfscript having been the original UDF)??
<cfcomponent>
<cffunction name="IsAlphanumeric" ....>
<cfscript>
function IsAlphanumeric(str) {
if (ReFindNoCase("[^a-z0-9}", str) eq 0)
return true;
else
return false;
}
</cfscript>
<cfset MyVar = IsAlpaNumeric(argument.String)>
<cfreturn MyVar>
</cffunction>
</cfcomponent>
Thanks

UDF:
<cffunction name="whatever" ...>
<!--- ... --->
</cffunction>
CFC:
<cfcomponent>
<cffunction name="whatever" ...>
<!--- ... --->
</cffunction>
</cfcomponent>
To call them you do this:
UDF:
<cfinclude template="myudf.cfm" />
<cfset whatever() />
CFC:
<cfinvoke component="mycfc" method="whatever" />
If you CFC is in the same directory as your calling code, you only need the
root of the filename (not the extension). If it's in a different directory,
you'll need the full path.

found on CFLIB)?

You shouldn't need to. If you need a utility function, it should be a
method of the CFC you're in. CFCs should stand on their own as much as
possible, so they don't need any external resources (other than method
arguments) to function. That's not always possible, but it usually is.
If you really have a function you need to use, and it doesn't make sense
to
put the function in the CFC directly, put it in another CFC that you
don't
instantiate, you just call methods on statically. In other words,
CFINVOKE
with the name of the CFC, not CFOBJECT or createObject() and then a
method
call on the object. You can then call that method from your CFC as if
it
where a UDF, and you don't have to include it anywhere first.

Hey All,
Can a UDF be used inside a CFC is the UDF is included in the template
that
calls the CFC? or the UDF is included via Application.cfm?
From what I've seen it cannot...but mabye my info is off ;-)
TIA
