The ClientToScreen function converts the client coordinates of a specified point to screen coordinates.
BOOL ClientToScreen(
HWND hWnd, |
// window handle for source coordinates |
LPPOINT lpPoint |
// pointer to structure containing screen coordinates |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The ClientToScreen function replaces the client coordinates in the POINT structure with the screen coordinates. The screen coordinates are relative to the upper-left corner of the screen.
