(Xojo Plugin) SFTP Upload from Local Filesystem

Demonstrates how to upload a file to an SSH server. There are no limitations on file size, and the file is streamed directly from the local filesystem.

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

Dim sftp As New Chilkat.SFtp

// Set some timeouts, in milliseconds:
sftp.ConnectTimeoutMs = 5000
sftp.IdleTimeoutMs = 10000

// 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 Int32
port = 22
Dim success As Boolean
success = sftp.Connect(hostname,port)
If (success <> True) Then
    System.DebugLog(sftp.LastErrorText)
    Return
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 <> True) Then
    System.DebugLog(sftp.LastErrorText)

End If

// After authenticating, the SFTP subsystem must be initialized:
success = sftp.InitializeSftp()
If (success <> True) Then
    System.DebugLog(sftp.LastErrorText)
    Return
End If

// Open a file for writing on the SSH server.
// If the file already exists, it is overwritten.
// (Specify "createNew" instead of "createTruncate" to
// prevent overwriting existing files.)
Dim handle As String
handle = sftp.OpenFile("hamlet.xml","writeOnly","createTruncate")
If (sftp.LastMethodSuccess <> True) Then
    System.DebugLog(sftp.LastErrorText)
    Return
End If

// Upload from the local file to the SSH server.
success = sftp.UploadFile(handle,"c:/temp/hamlet.xml")
If (success <> True) Then
    System.DebugLog(sftp.LastErrorText)
    Return
End If

// -----------------------------------------------------------------------------
// This is important.  You must close the handle on the server.
// Otherwise open handles will accumulate on the server until eventually a limit
// is reached and the server will fail on a call to OpenFile.
// -----------------------------------------------------------------------------

// Close the file.
success = sftp.CloseHandle(handle)
