Hello, starting with D2009 or D2010 you can also use the generic TObjectList<> from Generics.Collections and save those typecasts: vas MyList:TObjectList<HTTPMultipartdownloader>; begin MyList := TObjectList<HTTPMultipartdownloader>.Create(true); // create one downloader and add it... [..] MyList.Add(MyHTTPMultipartdownloader); // create one downloader... [..] MyList.Add(MyHTTPMultipartdownloader); // use them MyList[2].Tag := 4711; end; Greetings Markus -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
