oWin:SendMsg( <nMsg>, <nWParam>, <nLParam> ) -> <lSuccess>

------------------------------------------------------------------------------


 PARAMETER:

  <nMsg>       contains one of the Windows API messages ( WM_xxxx )
               The values are defined in WINAPI.CH

  <nWParam>    The value of this first INTEGER parameter is directly related 
               to the message <nMsg>

  <nLParam>    This LONG INT second parameter is also directly related to 
               the message.


 DESCRIPTION:

  ::SendMsg() places an API message in the message queue of the window,
  and and then waits until this message is processed. This is in contrast 
  to the ::PostMsg() Method, which immediately returns after dispatching
  the message.

  You find the Windows API messages in the WINAPI.CH include file.
