Is there a way to pass a wrap and unwrap a TObject descendent in an OleVariant? I am trying to pass a TObject across automation objects. I know it's not a good idea but I don't have a good alternative.
Something like this:
function GetMyObjAsVariant;
var
MyObj: TMyObj;
begin
MyObj := TMyObj.Create;
result := OleVariant(MyObj);
end;
Which would be used by a client as
var
MyObj: TMyObj;
begin
MyObj := GetMyObjAsVariant as TMyObj;
end;
This fails to compile, returning
E2015 Operator not applicable to this operand type.
