Demonstrates how to connect using implicit SSL on port 990. The FTP component connects using SSL on port 990, which is the de-facto standard FTP SSL port. Not all FTP servers support implicit SSL. An alternative is to use AUTH SSL (also called AUTH TLS).

Dim ftp As New Chilkat.Ftp2()

Dim success As Boolean

'  Any string unlocks the component for the 1st 30-days.
success = ftp.UnlockComponent("Anything for 30-day trial")
If (success <> true) Then
    MsgBox(ftp.LastErrorText)
    Exit Sub
End If


'  You may use this account for testing.
'  This account allows for directory listings and files
'  to be downloaded.  However, file uploads are not allowed.
ftp.Hostname = "ftp.secureftp-test.com"
ftp.Username = "test"
ftp.Password = "test"
ftp.Port = 990

'  We don't want AUTH SSL:
ftp.AuthTls = false

'  We want Implicit SSL:
ftp.Ssl = true

'  Connect and login to the FTP server.
success = ftp.Connect()
If (success <> true) Then
    MsgBox(ftp.LastErrorText)
    Exit Sub
Else
    '  LastErrorText contains information even when
    '  successful. This allows you to visually verify
    '  that the secure connection actually occurred.
    TextBox1.Text = TextBox1.Text & ftp.LastErrorText & vbCrLf
End If


MsgBox("FTPS Channel Established!")

'  Do whatever you're doing to do ...
'  upload files, download files, etc...

ftp.Disconnect()
