Demonstrate how to upload from a Chilkat StringBuilder object, and download into a StringBuilder object. VB.NET

Dim success As Boolean = False

' This example assumes Chilkat Ftp2 to have been previously unlocked.
' See Unlock Ftp2 for sample code.

Dim ftp As New Chilkat.Ftp2

ftp.Hostname = "www.my-ftp-server.com"
ftp.Username = "mFtpLogin"
ftp.Password = "myFtpPassword"

' Connect to the FTP server.
success = ftp.ConnectOnly()
If (success <> True) Then
    Debug.WriteLine(ftp.LastErrorText)
    Exit Sub
End If


' Authenticate with the FTP server.
success = ftp.LoginAfterConnectOnly()
If (success <> True) Then
    Debug.WriteLine(ftp.LastErrorText)
    Exit Sub
End If


Dim sbA As New Chilkat.StringBuilder
sbA.LoadFile("qa_data/hamlet.xml","utf-8")

' Upload the contents of sbA to the FTP server.
Dim bIncludeBOM As Boolean = False
Dim remoteFilename As String = "hamletFromSb.xml"

    Debug.WriteLine(ftp.LastErrorText)
    Exit Sub
End If


' Verify that sbA and sbB have the exact same contents.
Debug.WriteLine("size of sbA: " & sbA.Length)
Dim bCaseSensitive As Boolean = True

    Debug.WriteLine("Contents are equal. Success.")
Else
    Debug.WriteLine("Contents are NOT equal.  Failed.")
