Registering Windows Win32 Classes
2 answers
There is no need to register if you are using MFC because this will run in the background .. but if you are using win32 you need to register the Windows class in the WNDCLASS structure, if you want to uise windproc to handle custom messages see the MSDN link

even if you do not give the registration class, the system will have the class registered in the window.
see sample
