Demonstrates how to connect to the Inovis EDI VAN (FTP/SSL). C#

bool success = false;

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

Chilkat.Ftp2 ftp = new Chilkat.Ftp2();

ftp.Hostname = "ftpssl.gateway.inovisworks.net";
ftp.Username = "myLogin";
ftp.Password = "myPassword";

//  The Inovis EDI VAN requires Passive connections:
ftp.Passive = true;

//  Note: The Inovis documentation mentions an outbound
//  high port range of 40000-49999.  In passive mode, the
//  FTP server chooses the port number for the data
//  connection.  The Inovis server will choose a port number
//  in the range 40000-49999.  To establish the data connection,
//  your firewall must allow outgoing connections in that port
//  range. 

//  This tells Chilkat FTP2 to establish
//  an AUTH TLS secure channel after connecting
//  on the standard FTP port 21.
ftp.AuthTls = true;

//  You'll probably need this property set to true if you're
//  behind a NAT router or firewall.
ftp.PassiveUseHostAddr = true;

//  The Ssl property is for establishing an implicit SSL connection
//  on port 990.  Do not set it to true.  The Inovis VAN
//  uses explicit encryption (SSL/TLS).
ftp.Ssl = false;

//  The Chilkat FTP component automatically sends a "FEAT";
//  command after connecting.  This allows the component
//  to better know the FTP server's capabilities.
//  The Invois server doesn't recognize the FEAT command,
//  so disable it:
ftp.AutoFeat = false;

//  Connect, convert to TLS, and login to the FTP server.

    //  that the secure connection actually occurred.
