SFTP Fsync -- Flush an Open File on the Server

See more SFTP Examples

Demonstrates how to flush the contents of an open file on the server. This example only works for servers that implement the fsync@openssh.com extension.

Note: This example requires Chilkat v9.5.0.71 or later.

VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

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

set sftp = CreateObject("Chilkat.SFtp")

' Pass a domain or IP address..
success = sftp.Connect("my-sftp-server.com",22)
If (success = 1) Then
    success = sftp.AuthenticatePw("mySFtpLogin","mySFtpPassword")
End If

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

If (success <> 1) Then
    outFile.WriteLine(sftp.LastErrorText)
    WScript.Quit
End If

' Open a file on the server for writing.
handle = sftp.OpenFile("myTest.txt","writeOnly","createTruncate")
If (sftp.LastMethodSuccess <> 1) Then
    outFile.WriteLine(sftp.LastErrorText)
    WScript.Quit

' Write some text to the file:
success = sftp.WriteFileText(handle,"ansi","abcdefghijklmnopqrstuvwxyz")
If (success <> 1) Then
    outFile.WriteLine(sftp.LastErrorText)
    WScript.Quit
End If

' Make sure the server flushes what we wrote to the disk..
' (this is requires a server that implements the fsync@openssh.com SFTP protocol extension)
success = sftp.Fsync(handle)
If (success <> 1) Then
    outFile.WriteLine(sftp.LastErrorText)
    WScript.Quit
End If

If (success <> 1) Then
    outFile.WriteLine(sftp.LastErrorText)
    WScript.Quit
End If

' Close the file.
success = sftp.CloseHandle(handle)
If (success <> 1) Then
    outFile.WriteLine(sftp.LastErrorText)
