And even more questions: What about the record INTERNET_PROXY_INFO (http://msdn.microsoft.com/en-us/library/aa385148.aspx)? Problem is that LPCTSTR maps to UNICODE in any case, wininet.h does not declare an A-version. So what about declaring a dummy INTERNET_PROXY_INFOA record and use InternetQueryOptionA for everything, requires a few explicit conversions to UnicodeString but that won't hurt since these strings may IMO contain plain ASCII printable only. -- Arno Garrels -- 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
