David, we suspected a firewall at first, but it was ruled out a few days ago. If ftp.exe doesn't do PASV at then I was accidentally wasting my time. Web searches on this matter now hint that you're right, but I would never have guessed such a stupid thing could be true. My little C# client is correctly getting files on the FTP server and all I'm doing is this: var client = new WebClient<http://msdn.microsoft.com/en-us/library/system.net.webclient(v=vs.100).aspx> (); client.Credentials = new NetworkCredentials("user", "password"); client.BaseAddress = "ftp://ftp.myserver.com";; byte[] buffer = client.DownloadData("getme.txt");
I didn't expect this to work at first, thinking I'd have to change modes or properties or some other trickery, but it works! I didn't even have to use the FtpWebRequest<http://msdn.microsoft.com/en-us/library/system.net.ftpwebrequest(v=vs.100).aspx>class. Now I think the ball is to be passed over to the C++ programmer to see what he's doing that is different. His code is still crashing trying to get a file. Greg
