Если использую function CreateFormShowForm(str:String;bool:boolean;sz:Word ):Boolean в отдельном проекте (exe) все нормально.
А вот когда использую в DLL

и создаю у объекта функцию

То в приложении используя

Код:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

procedure TForm1.Button3Click(Sender: TObject); var   str:String;   bool:Boolean; ip2:OleVariant; begin   Bool:=true; str:= 'C:\S1.jpg';  ip2:=CreateOleObject('Ip2Com_events.Ip2Com'); if not ip2.F_PICTER_SHOW(str,bool,1) then   ShowMessage('Ошибка');   end;
