HELP - COM Local Server

Can anyone tell me why it is that when I create a local server and successfully "CoRegisterClassObject" my class factory, my "client" application is unable to "CoCreateInstance" the COM object. I've stepped through the code, and I see the class factory return the correct interface. However, the client receives "No such interface is supported."

have you registered proxy stub dll ?

Do I have to register something else besides the class factory in my EXE application?

Thanks for any help, the problem was I didn't have the proxy stub dll registered.

For a local server you have to do marshaling to pass data.
This can be done in 3 ways.
Standard marshalling : make the proxystub dll using nmake and register it using regsvr32.
Typelibrary marshalling : if you use IDispatch interface / Ole automation types only in your server
you can use the typelib marshaller supplied by microsoft ( oleaut32.dll )
Custom marshalling : You can implement IMarshal interface and write your own code.

most cases standard marshalling will do.
