All,
I hope you could help in this.
I write VC++ COM Automation objects. I have been writting them for ASP for a couple of years now.
I recently started using ColdFusion MX7.
I try to instanciate know good objects of mine and I get an Automation Error every time.

I can use MS COM Objects like FSO and others but I am not sure why my compiled COM objects don't work.
They work fine in ASP.
They are registered properly with regsvr32, but I am not sure if Cold Fusion needs a type lib or a proxy to call my COM Objects.

I some one could shed some light on ths I would be verry thankfull.

Send Me an email.

In the first place I've never used ColdFusion.

I have found that there are some requirements for COM objects used in CF.

http://livedocs.macromedia.com/coldfusion/6.1/htmldocs/cfobje21.htm

Objects has to be thread safe (threading model "free" or "both") to work in MTA.

References to variables as method parameters should be placed in ""

Maybe there are some other requirements also ?

Have you checked error codes ?

This for example

http://livedocs.macromedia.com/coldfusion/6/Developing_ColdFusion_MX_Applications_with_CFML/cfobject4.htm

states that "These components should allow late binding; that is, they should implement the IDispatch interface. "

And "Common Pitfalls of using COM objects with ColdFusion ":

Hope this will help a little.
