Hi, I'm developing a graphic application for the flight simulation world where the window of the program must be not resizable. The window is created with CreateWindowEx but I can't find the correct window's style (or type) to prevent the user from resizing the window dragging the borders (the borders must be visible though). I found the way to hide the maximize button but not the way to "lock" the borders. Any suggestion? Thank you, regards. Bob

This should do it:
DWORD dwstyle = WS_OVERLAPPEDWINDOW & (~WS_THICKFRAME);
I.e. use the overlapped window style (standard), but remove the thick frame, making it non-resizable.

Thank you for your answer...it worked perfectly !!

Regards,

Bob
