The amazing yet ellusive ->* operator appears to require an object of a known type. Suppose you want to call a member function of an arbitrary object? For example, in the creation of a service, I designed an interface to allow consumers to pass in a "this" pointer and their callback function. What's the recommended way to dish up the program counter to them when all I have are these two items? void *pThis; typedef BOOL (CALLBACK * LPFGETMESSAGE)(IN EMS_HANDLE hSentMessage, IN CString &Body, IN BOOL bSuccess); I have no way to find out what type of object "pThis" is, nor do I WANT to know.
