oDlg:cToChar( <hActiveWnd> ) -> <cDialog>

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

 PARAMETER:

  <hActiveWnd> The handle of the main window that should be included in 
               the structure built by ::cToChar()


 RETURNS:

  <cDialog>    The dialog structure. This structure is stored as a
               character string because Clipper has no provisions for making 
               and using structures.


 DESCRIPTION:

  The ::cToChar() method creates a string that has the structure that is
  needed by the Windows API functions that create dialog boxes.
  The information is stored in string because Clipper unfortunately has no 
  knowledge of structure's since this is not a part of the Clipper language.
