Register COM implementation

Question

I am new to COM programming. I have a COM object (and the associated IClassFactory) everything is ready to work, but I can’t understand how to register the resulting DLL for use by other programs. I also miss the number of GUIDs that I need to scroll.

The COM object I'm trying to register implements the IAudioSessionEvents interface.

I came across the DllRegisterServer and DllUnregisterServer functions, but I did not find clear demonstrations of their use. What keys do they deal with, how are they called, what and when, etc.?

Thanks,
Kevin Montrose

Quite often, the easiest way to implement self-registration is to use the ATL server classes, have a global variable that comes from CComModule (or another similar class) and define COM_MAP in your module. Then you request the com module to handle registration based on the .rgs files that you added to your project.
