GetClientRect The GetClientRect function retrieves the coordinates of a window’s client area. The client coordinates specify the upper-left and lower-right corners of the client area. Because client coordinates are relative to the upper-left corner of a window’s client area, the coordinates of the upper-left corner are (0,0).
