I have VC++ 6.0 socket application that works fine till Windows XP and fails to work in Vista. I ran as administrator, disabled firewall, set the port in firewall and nothing works. I also ported application to VS2008 VC++, still does not work under Vista. CAsyncSocket:OnReceive function is never called in Vista but it works just fine in XP or older. Any help is greatly appreciated. If someone leads to some sample code that would be great.Thanks,
