I need to use a COM DLL (an in-process COM server) in an application. Its type library is built into the DLL file. No *_i.c file available. In order to use CoCreateInstance function, I need to know IIDs of the interfaces.

Now how to get the IID vlaues?

You can use #import yourserver.tlb where tlb is the type library of your COM server dll. This would give access to the IIDs of the interfaces and COM objects in the server.

See an ATL book or MSDN for all the options to the #import directive

To see the IIDs you can use the OLE/COM ObjectViewer utility in VisualStudio
