ATL::CComModule::RegisterServer

Question

What EXACLTY (what registry keys it writes) does the ATL::CComModule::RegisterServer(TRUE) call do?

Answer 1

For each class that uses the OBJECT_ENTRY_AUTO macro, it will run the corresponding registry script resource (.rgs file) listed in your resource file, as identified by the DECLARE_REGISTRY_RESOURCEID macro.

Additionally, because you are passing TRUE for bRegTypeLib, it will also run the registry script identified by DECLARE_REGISTRY_APPID_RESOURCEID.
