int InetFTPSetPassiveMode (int FTPHandle, int passiveMode);
Sets the manner in which the FTP data connection is established. If you turn on passive mode, the FTP client initiates the data connection to the FTP server. If you turn off passive mode, the FTP server initiates the data connection to the FTP client.
You generally need to use passive mode when the FTP client machine is behind a firewall.
Call this function immediately after calling InetFTPLogin or InetFTPLoginEx.
