(VB.NET UWP/WinRT) SFTP Simplified Upload

Demonstrates how to upload a file to an SSH server in the simplest way -- by calling UploadFileByName and passing remote and local filepaths.

'  Important: It is helpful to send the contents of the
'  sftp.LastErrorText property when requesting support.

Dim sftp As New Chilkat.SFtp

'  Any string automatically begins a fully-functional 30-day trial.
Dim success As Boolean = sftp.UnlockComponent("Anything for 30-day trial")
If (success <> True) Then
    Debug.WriteLine(sftp.LastErrorText)
    Exit Sub
End If


'  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 port As Integer
Dim hostname As String
hostname = "www.my-ssh-server.com"
port = 22
success = Await sftp.ConnectAsync(hostname,port)
If (success <> True) Then
    Debug.WriteLine(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 = Await sftp.AuthenticatePwAsync("myLogin","myPassword")
If (success <> True) Then
    Debug.WriteLine(sftp.LastErrorText)
    Exit Sub
End If


'  After authenticating, the SFTP subsystem must be initialized:
success = Await sftp.InitializeSftpAsync()
If (success <> True) Then
    Debug.WriteLine(sftp.LastErrorText)
    Exit Sub
End If


'  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 = "hamlet.xml"
Dim localFilePath As String = "c:/temp/hamlet.xml"

success = Await sftp.UploadFileByNameAsync(remoteFilePath,localFilePath)
