How To Translate Client Coordinates to Screen Coordinates

Summary

The GetClientRect function always returns the coordinates (0, 0) for the origin of a window. This behavior is documented in the "Microsoft Windows Software Development Kit (SDK) Programmer's Reference" manual.

More Information

To determine the screen coordinates for the client area of a window, call the ClientToScreen function to translate the client coordinates returned by GetClientRect into screen coordinates. The following code demonstrates how to use the two functions together:

   RECT rMyRect;

GetClientRect(hwnd, (LPRECT)&rMyRect);
ClientToScreen(hwnd, (LPPOINT)&rMyRect.left);
ClientToScreen(hwnd, (LPPOINT)&rMyRect.right);
