Hi.

I would like to put a extra button biside the system buttons for Maximize,
Minimize and Close in the Title bar, any subjections?

Can anyone point me in the right direction? Is there any sample code
regarding this?

Thanks,
Clive Rudd

Basically you need to do some of your own painting in the non-client
area of the window. If you study the source code in the MFC source file
c:\msdev\mfc\src\BARDOCK.CPP
you'll see how to do this.
Also, there are fun things in \msdev\include\winuser.h
which are NOT wrapped in the MFC for doing non-client painting.
For example, there are functions like this:

WINUSERAPI BOOL WINAPI DrawEdge(HDC hdc, LPRECT qrc, UINT edge, UINT grfFlags);
WINUSERAPI BOOL    WINAPI DrawFrameControl(HDC, LPRECT, UINT, UINT);
WINUSERAPI BOOL    WINAPI DrawCaption(HWND, HDC, CONST RECT *, UINT);

Of course, you'll have to trap mouse events on your new button.
Just look up all the window messages which start witn WM_NC
because those are the ones for Non-client stuff.
Setup your message maps, and you're off to the races...
