Using the WinApi GetWindowRect() it returns the complete window size, but I would like to get the size without the borders and the title bar, something like the red square:

There is any functions to do that?
Thanks

The Windows API function you are looking for is
GetClientRect. If you subsequently need to convert these coordinates into screen relative coordinates, callClientToScreen.
