Are you working in MFC, if yes then you can use the class wizard to generate the class based from OCX,TLB or DLL

<pre lang="text"> What is the basic difference in processing system messages in MFC? Should I use message map or WindowProc? In my included sample the WindowProc get executed first ( as expected ) , but I really do not do any message processing in this case. So my secondary question would be - what is considered by OS as processed message? </pre>
Never. MFC has an inbuilt message pump and MessageProc() handler which distributes the messages according to your MESSAGE_MAP entries. If you add your own MessageProc() then you break the connection between those entries and your message handlers.
One of these days I'm going to think of a really clever signature.
I would agree with NEVER... use message maps in MFC. If you find it doesn't do something specific that you needs, that's when you go around the framework, other than that... it's best to try to use the framework that's there.
Messages use WindowProcs, but MFC handles that for you. There's really very few cases where you'd have to go around what MFC already does. Only reason to code your own WindowProcs would really be if you're doing native Win32 coding.
Because WINVER is used in Windows.h and many other header files, it is set to the smallest supported value in Windows.h if not already defined.
It is a definition that decides which API functions and structures can be used. Which compiler is used does not care. But to use features introduced with newer Windows versions, you must use newer include files from a newer Windows SDK.
