MFC Library Reference CWnd::ClientToScreen Converts the client coordinates of a given point or rectangle on the display to screen coordinates.void ClientToScreen( LPPOINT lpPoint ) const; void ClientToScreen( LPRECT lpRect ) const; Parameters lpPoint Points to a POINT structure or CPoint object that contains the client coordinates to be converted. lpRect Points to a RECT structure or CRect object that contains the client coordinates to be converted. Res The ClientToScreen member function uses the client coordinates in the POINT or RECT structure or the CPoint or CRect object pointed to by lpPoint or lpRect to compute new screen coordinates; it then replaces the coordinates in the structure with the new coordinates. The new screen coordinates are relative to the upper-left corner of the system display. The ClientToScreen member function assumes that the given point or rectangle is in client coordinates.Example // resize dialog to client's size void CAboutDlg::OnButton1() { CRect myRect; GetClientRect(&myRect); ClientToScreen(myRect); MoveWindow(myRect.left, myRect.top, myRect.Width(), myRect.Height()); } See Also CWnd Overview | Class Members | Hierarchy Chart | CWnd::ScreenToClient | ClientToScreen
