    Callback to perform dispatch interface procedure call by ID.

    Declaration

    Source position: objpash.inc line 760

    var
  DispCallByIDProc: CodePointer = Pointer;

    Description

    VarDispProc is called by the compiler if it needs to perform an interface call from a variant which contains a dispatch interface. For instance, the following call: 

    Var
  V : OleVariant;
begin
  (V as IWord).OpenDocument('c:\temp\mydoc.doc');
end;

    where IWord is a dispatch interface is encoded by the compiler and passed to DispCallByIDProc.

    This pointer must be set by a routine that calls the OS COM handling routines.
