I can get this one it to work on a local ftp server but not on a outside one
http://www.allapi.net/classlib/class.php?id=23

i think you can import the win32 calls but i can't get that to work either.
GetlastError after InternetConnect always returns 12029 (
ERROR_INTERNET_CANNOT_CONNECT) even though i am connect to the internet.

public class ftp
{
public const UInt32 INTERNET_OPEN_TYPE_PRECONFIG = 0;
public const long INTERNET_OPEN_TYPE_DIRECT = 1;

private static extern Int32 InternetConnectW(Int32 hInternet,

if(lInternetHandle == 0)
MessageBox.Show("BAD");
else
MessageBox.Show("Good");

return (lInternetHandle > 0);
}

strFTPServerName,

return (lTranferredOK > 0);
}

public void CloseFTP()
{

InternetCloseHandle(lInternetHandle);
}
}

There are FTP components available for CF already. You don't have
to write your own unless you just want to. There is an FTP component included
in IP*Works! .Net CF Edition (you can find this at www.nsoftware.com/download/).
There is also an SSL enabled FTPS component available as
well.
