I'm building a custom COM object (a DShow filter which derives from a DShow base class) but no other program but mine needs to know about this particular type. How can create an instance of this class for use in a COM framework ? Thanks. [edited by - cnstrnd on January 18, 2004 3:51:02 PM]

Use GUIDgen to create a CLSID and an IID, register your COM object, and use CoCreateInstance() as normal.

On the other hand, if only your program needs to use it, why bother making it COM?

You can just ''new'' it if you are following the examples with the SDK. If you are using the ATL, then make it like any other COM object.

Ok thanks, I was over complicating on this.
''new'' works.
