SFTP Upload with Bandwidth Throttling

Demonstrates how to upload a file to an SSH server in the simplest way with bandwidth throttling. Bandwidth throttling for all SFTP communications can be achieved by simply setting the BandwidthThrottleUp or BandwidthThrottleDown properties. (One limits the transfer rate for uploads, the other for downloads.) Visual Basic 6.0

Dim success As Long
success = 0

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

Dim sftp As New ChilkatSFtp

' Set some timeouts, in milliseconds:
sftp.ConnectTimeoutMs = 15000
sftp.IdleTimeoutMs = 15000

' Connect to the SSH server.  
' The standard SSH port = 22
' The hostname may be a hostname or IP address.
Dim hostname As String
hostname = "sftp.example.com"
Dim port As Long
port = 22
success = sftp.Connect(hostname,port)
If (success <> 1) Then
    Debug.Print sftp.LastErrorText
    Exit Sub
End If

' Authenticate with the SSH server.  Chilkat SFTP supports
' both password-based authenication as well as public-key
' authentication.  This example uses password authenication.
success = sftp.AuthenticatePw("myLogin","myPassword")
If (success <> 1) Then
    Debug.Print sftp.LastErrorText
    Exit Sub
End If

' After authenticating, the SFTP subsystem must be initialized:
success = sftp.InitializeSftp()
If (success <> 1) Then
    Debug.Print sftp.LastErrorText
    Exit Sub
End If

' Limit the transfer rate (bandwidth throttle) to 64K per second.
sftp.BandwidthThrottleUp = 65536

' Upload from the local file to the SSH server.
' Important -- the remote filepath is the 1st argument,
' the local filepath is the 2nd argument;
Dim remoteFilePath As String
remoteFilePath = "hamlet.xml"
Dim localFilePath As String
localFilePath = "c:/temp/hamlet.xml"

success = sftp.UploadFileByName(remoteFilePath,localFilePath)
If (success <> 1) Then
    Debug.Print sftp.LastErrorText
    Exit Sub
End If

Debug.Print "Success."
