###Remarks###
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 <a href="GUICtrlRead.htm">GUICtrlRead()</a> and <a href="GUICtrlUpdate Management.htm">GUICtrlUpdate...</a>. range of functions.

The parameters (wParam and lParam) can be an integer or a string.

<a href="GUICtrlSendMsg.htm">GUICtrlSendMsg()</a> 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 <a href="GUICtrlRecvMsg.htm">GUICtrlRecvMsg()</a>.
