Simple example to upload a file to an FTP server using passive mode.

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


ftp.Hostname = "www.example-code.com"
ftp.Username = "****"
ftp.Password = "****"

' The default data transfer mode is "Active" as opposed to "Passive".
' Change it to Passive by setting the Passive property:
ftp.Passive = true

' Connect and login to the FTP server.
success = ftp.Connect()
If (success <> true) Then
    MsgBox(ftp.LastErrorText)
    Exit Sub
End If


' Change to the remote directory where the file will be uploaded.
success = ftp.ChangeRemoteDir("junk")
If (success <> true) Then
    MsgBox(ftp.LastErrorText)
    Exit Sub
End If


' Upload a file.
Dim localFilename As String
localFilename = "hamlet.xml"
Dim remoteFilename As String
remoteFilename = "hamlet.xml"

success = ftp.PutFile(localFilename,remoteFilename)
If (success <> true) Then
    MsgBox(ftp.LastErrorText)
    Exit Sub
End If


ftp.Disconnect()

MsgBox("File Uploaded!")
