Type myType =Type.GetTypeFromProgID(theProgramID,theServer); if(myType==null) { throw new Exception("Invalid ProgID or Server."); } Console.WriteLine("GUID for ProgID DirControl.DirList.1 is {0}.", myType.GUID); } catch(Exception e) { Console.WriteLine("An exception occurred."); Console.WriteLine("Source: {0}" , e.Source); Console.WriteLine("Message: {0}" , e.Message); } } }
