I recently bought a new laptop and put Vista Home Premium on it. My older laptop is XP. I have an app which I developed which does FTP which send Postscript files to a Postscript printer after it prepares them.
On XP, the app worked fine. On Vista, the connect to the server succeeded, but the upload command failed. I tried Firefox, Explorer, and Filezilla to make the transfer - they all failed as well; The problem seems to be in some of the cases (Firefox, FileZilla) that the FTP server on the printer does not allow the DIR command; in other cases it seems that the server connection opens and closes immediately.
When I went searching, I saw on MSDN that Visual Studio 2005 has open unworkaroundable issues with FTP: http://msdn2.microsoft.com/en-us/vstudio/aa972193.aspx
so I changed the way my app sends files to the printer, and am waiting for SP1.
