Answer Posted / aditya
The WM_PAINT message is sent when the system or another
application makes a request to paint a portion of an
application's window. The message is sent when the
UpdateWindow or RedrawWindow function is called, or by the
DispatchMessage function when the application obtains a
WM_PAINT message by using the GetMessage or PeekMessage
function.
A window receives this message through its WindowProc
function.
