Thanks for the info, Matt.
I think I've got a handle on those methods.
One thing I still haven't been able to get to work
is setting up an "init" function for my db in a cfc.
Can you explain how that work and show me an example
of the code I need to put in a cfc.
I tried this that someone gave me:
<cffunction name="init">
<cfargument name="dsn">
<cfset variables.dsn = arguments.dsn />
<cfreturn this>
</cffunction>
But that doesn't make sense to me. My dsn is set
in application.cfm like so: cfset application.dsn = "myDB".
So why, "variables.dsn" above?
I just don't understand what the code is doing.
Why is variables.dsn being set to be the value of
arguments.dsn? And what exactly does "cfreturn this" do?
I'm just lacking in my understanding, I think, of what the CFC
is providing for the calling page with this type of code.
Perhaps it's time to get the CF8 version of CFWACK.
(Last one I got was for CF4.5... :o)
