the function.
I've been using the way of the Jedi, Ray Camden :), lately. Setup a
config.ini file with your dsn name, un, pw, etc.. and have your CFC
read theses values in when its instantiated. I've actually gone a
step further and created a 'parent' CFC that my other CFCs extend.
This parent holds the config.ini settings.

Subject: Re: cfc variables
To: CF-Talk <[EMAIL PROTECTED]>
not real sure how that would work
say i have the cfc
<!--- get agents name --->
<cfcomponent>
<cffunction name="mainpage" access="public" returntype="query"
hint="get mainpage info">
<!--- set site dsn connection --->
<cfset dsn = "whenever">
<cfset un = "whoever">
<cfset pw = "whatever">
<cfquery name="qMP" datasource="#dsn#" username="#un#" password="#pw#">
SELECT *
FROM mainpage
</cfquery>
<cfreturn qMP>
</cffunction>
</cfcomponent>
and then the object call from the application.cfm template
<cfobject name="amainPage" component="components.mainpage">
how would it be put in?
thanks :)
