Callback to perform dispatch interface procedure call by name.

Declaration

Source position: varianth.inc line 201

var VarDispProc: pointer;

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

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

is encoded by the compiler and passed to VarDispProc.

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