(Visual Basic 6.0) SFTP Upload - Synchronize Directory Tree

Demonstrates how to upload files to synchronize a local directory tree with a remote directory tree. The SyncTreeUpload method recursively descends a local directory tree and uploads files based on existence, last-mod date/time and/or size differences.

'  This example requires the Chilkat SFTP API to have been previously unlocked.
'  See Unlock Chilkat SFTP for sample code.

Dim sftp As New ChilkatSFtp

Dim success As Long
success = sftp.Connect("my-ssh-server.com",22)
If (success = 1) Then
    success = sftp.AuthenticatePw("mySshLogin","mySshPassword")
End If

If (success = 1) Then
    success = sftp.InitializeSftp()
End If

If (success <> 1) Then
    Debug.Print sftp.LastErrorText
    Exit Sub
End If

'  Synchronize (by uploading) the local directory tree rooted at "qa_data/sftpUploadTree"
'  with the remote directory tree rooted at "syncUploadTest"
'  Both directories are relative paths.  The remote directory
'  is relative to the HOME directory of the SSH user account.
'  The local directory is relative to the current working directory of the process.
'  It is also possible to use absolute paths.

Dim remoteDir As String
remoteDir = "syncUploadTest"
Dim localDir As String
localDir = "qa_data/sftpUploadTree"

'  Possible modes that can be passed to the SyncTreeUpload method are:
'  mode=0: Upload all files
'  mode=1: Upload all files that do not exist on the server.
'  mode=2: Upload newer or non-existant files.
'  mode=3: Upload only newer files. If a file does not already exist on the server, it is not uploaded.
'  mode=4: transfer missing files or files with size differences.
'  mode=5: same as mode 4, but also newer files.

'  This example will use mode 5 to upload missing, newer, or files with size differences.
Dim mode As Long
mode = 5
'  This example turns on recursion to synchronize the entire tree.
'  Recursion can be turned off to synchronize the files of a single directory.
Dim recursive As Long
recursive = 1
success = sftp.SyncTreeUpload(localDir,remoteDir,mode,recursive)
If (success <> 1) Then
    Debug.Print sftp.LastErrorText
    Exit Sub
End If

Debug.Print "Success."
