>AFAIK, all ActiveX controls must be registered. When registered, they make some entries into the registry. You can usually tell what the program ID (eg. the string you pass CREATEOBJECT()) is by looking in the registry. I normally just do a search for the DLL name. There will be a ProgID node. The program ID is contained there. If you don't have to register the DLL, then it's probably not an ActiveX control. It's probably a standard DLL. In that case, you have to use DECLARE to access it. You'll definitely want docs in that case (although in a pinch you can use the DEPENDS.EXE included w/Visual Studio to figure out the DECLARE call).

Hi Paul

I have registered the dll and now I don't get an error when trying to use createobject.

Thanks
