One is private and one is public. For example, say you had a cfc that did encrypting. For some reason you wanted to store the public key in the cfcomponent and use it in the function in that component. Further suppose you didn't want anyone to change / see the key. If you used 'this' every one could 'see' the key, if you used var you could use the variable inside the component and not allow it to be 'seen' or changed.
Hope that helps, Rob -----Original Message----- From: Adrocknaphobia Jones [mailto:[EMAIL PROTECTED]] Sent: Monday, January 06, 2003 1:41 PM To: CF-Talk Subject: RE: CFC - Var vs. This Right. But what's the difference outside of syntax. Would I want to use one over the other? Why would I want to use var over this inside a CF is this is much more flexible?

"this" is the public variable scope for a CFC instance. "var" is a keyword used to declare local function variables. "this" can be used anywhere inside a CFC. "var" can only be used immediately proceeding a function declaration or argument specification of a function declaration.
