Hello all.

I've been looking all over the net for examples of how to use a
callback out of FtpGetFile in C# or VB.net so I can display progress to
the user. No such luck. I'm new to C# and am having problems
understanding how to use the callback with InternetSetStatusCallback.

Does anybody have any examples of how to implement a callback when
using FTP ?

Any help would be most appreciated.

Thanks,
Mark

The framework does not include a ftp client, which one are you using?

A workaround, if you know the target file AND the expected size you can use
a timer in the UI to check the size at intervals and update your UI.

Of course, you are downloading it in a background thread don't u?

I've just found snippets of various things around and have FTP working
just fine. I just wanted the ability to update a progress bar out of
my download which uses FtpGetFile. I know you can implement a callback
out of this api, but I haven't been able to figure out how yet.
