ICatRegister interface in managed c++ Posted by snchandra95 NO[at]SPAM yahoo.com at 9/20/2004 1:30:15 PM Hi!
How do you use ICatRegister interface in a managed c++ project? I need
to add some category information and want to use this interface. I
know you can use ComRegisterFunctionAttribute and directly add it to
the registry. Is there a way to use ICatRegister interface instead to
do this?

methods GetIDsOfNames and Invoke which have a special implementation in the
original C++ COM servers. All the logic of these COM servers depend...more >>
