BOOL TranslateMDISysAccel(hWndClient,lpMsg)
This function processes keyboard accelerators for multiple document interface (MDI) child window System-menu commands. The TranslateMDISysAccel function translates WM_KEYUP and WM_KEYDOWN messages to WM_SYSCOMMAND messages. The high-order word of the lParam parameter of the WM_SYSCOMMAND message contains the value 1 to differentiate the message from messages sent by menus or controls.
