I am interested in repeatadly sending files through FTP from my software.

As my project compiles and runs as a system service, Microsoft does not recommend (or even blocks) using the WinInet.

Can I use other libraries,

or else,

Where can I get (or even purchase) a reliable object that will allow me to send the files through FTP?

Can you provide the reference that says WinIne/FTP is blocked when running as a system service?

If the blocking is caused by a security problem, you can use LogonUser and ImpersonateLoggedOnUser before starting the WinInet APIs.  This is a common technique for services.

I found one reference http://search.microsoft.com/gomsuri.asp?n=1&c=rp_Results&siteid=us/dev&target=http://support.microsoft.com/support/kb/articles/q238/4/25.asp

But it seems to indicate that the problem is seen only with SSL and/or a large number of simultaneous connections.

if its going to be a service that uses FTP when no user has logged on then use Winsock, better try to find a socket based FTP implementation, you may find some samples on FTP using sockets, so you dont have to implement everything from scratch.

Otherwise as mentioned by DanRollins Impersonate a user.

Hmmm, that's news to me.  That means that the various Wininet apps I've written don't really work.
