Send a message to a control.
GUICtrlSendMsg ( controlID, msg , wParam, lParam )
This function allows the sending of special Windows messages directly to the control using the SendMessage API. It is used to enable special control features not available with the simple GUICtrlRead() and GUICtrlUpdate.... range of functions.
The parameters (wParam and lParam) can be an integer or a string.
GUICtrlSendMsg() should be used for messages that have no special return types. For more advanced messages where you must be able to receive extra data you must use GUICtrlRecvMsg().
