Callback to perform dispatch interface procedure call by ID.
Source position: objpash.inc line 349
var DispCallByIDProc: pointer; |
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.
