Thanks David - It was my understanding that CF handles the destruction also
but I have not been able to locate a written reference for this.
As always - you get th the heart of the matter.

Subject: RE: COM Object
You can iterate through all of the publicly available Methods, Properties,
Classes, Events, Enums, and Types available in a COM object with OLEView
(Visual Studio Tools). What is supposed to happen is that a COM object is
supposed to be destroyed with Release() (this is a *hidden* COM interface,
seen in Visual C++ but not VB) and then the pointer should be set to a null
pointer (0). This happens in Visual Basic, WSH, and VBScript like so:
Set myObj = Nothing
and in JScript like this:
myObj = null;
It was my impression that ColdFusion handled Construction/Destruction of
object references. Is this a correct statement: "ColdFusion does Object
Pooling." If so, you would need to decide if you want this functionality.
MTS *sort of* does object pooling (it doesn't work right in NT, and some say
the same about W2K. I don't like MTS because if additional overhead
incurred in websites)
If you are worried about the object destruction, then in CFSCRIPT I would do
something like this (not tested - not sure if this is needed - like I said,
doesn't CF handle destruction?):
myObj = 0;
Or
myObj = null; // is NULL is a valid constant in CF?????
assuming myObj was a correctly instantiated object.

I don't know if that's entirely true. How can you determine that all
COM objects have the Reset() method? Is this something built into
Microsoft's COM specification?

Trying using the Reset Function. This clears up the memory and gets it
ready for the next transaction.
<CFSET whatever.reset()>

Can anyone give some insight into how memory is cleaned up after a COM
object has been processed by the <CFOBJECT> tag?
