Log file contains only errors specific to session. You may have some script level error as well, such as unrecognised command. Such error can be seen in the output only (processWinSCP.StandardOutput.ReadToEnd). Post the output if you need a help.

Re: Console Script Report No Error Yet .NET Apps Do Report Error

I am very aware of that reference.

My application decides that an error has happened through the use of your examples from your guide here.

Here's a snip of my code:
Dim processWinSCP As Process = New Process()
 
Dim logname As String
 
logname = "C:\log.txt"
 
' Build the Process
processWinSCP.StartInfo.FileName = "C:\Program Files\WinSCP\WinSCP.com"
processWinSCP.StartInfo.Arguments = "/log=" + logname
processWinSCP.StartInfo.UseShellExecute = False
processWinSCP.StartInfo.RedirectStandardInput = True
processWinSCP.StartInfo.RedirectStandardOutput = True
processWinSCP.StartInfo.CreateNoWindow = True
processWinSCP.Start()
 
' Feed in the scripting commands
processWinSCP.StandardInput.WriteLine("option batch abort")
processWinSCP.StandardInput.WriteLine("option confirm off")
processWinSCP.StandardInput.WriteLine("open sftp://userName:passWord@ftp-site.com:22 -hostkey=""ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"" -timeout=180 ")
processWinSCP.StandardInput.WriteLine("cd /datafiles")
processWinSCP.StandardInput.WriteLine("option transfer binary")
processWinSCP.StandardInput.WriteLine("get -preservetime BigMotherOfAnXMLFile.xml C:\BigMotherOfAnXMLFile.xml ")
processWinSCP.StandardInput.WriteLine("close")
 
' Collect all output (not used in this example)
Dim output As String = processWinSCP.StandardOutput.ReadToEnd()
 
Debug.Print(output)
 
' Wait until WinSCP finishes
processWinSCP.WaitForExit()
 
 
' Success (0) or error?
If processWinSCP.ExitCode <> 0 Then
 
        Console.WriteLine("Error occured")
 
End If

How does one determine the specific cause for a failure when the ExitCode is one? The only resource is to visually examine the log?

How does your application decide that error happens?

In all logs, from apps and console, I see a line with "Status/error code: 1". I am assuming that means an error happened. Is this a correct assumption, an error did occurr? If so, how do I find out the error?

That's wrong assumption.

Please read FAQ. If that does not help, come back.

Console Script Report No Error Yet .NET Apps Do Report Error

My problem is my applications are telling me an error happened. The console execution of the original script does not report an error. So I am very confused as to whom to believe. In every case, my downloaded test file is just fine. It more than 7 MB in size.

I first tested the script in console then copied it to VS 2008 in both VB.NET and C#.

The script and the .NET applications are based upon your samples in the .NET Guide. Both apps suggest the exit code is one (an error ocurred). The script run in console does not report an error.

In all logs, from apps and console, I see a line with "Status/error code: 1". I am assuming that means an error happened. Is this a correct assumption, an error did occurr? If so, how do I find out the error?

Here's my script:

    option batch abort
    option confirm off
    open sftp://userName:passWord@ftp.site.com:22 -hostkey="ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx" -timeout=180
    cd /datafiles
    option transfer binary
    get -preservetime BigMotherOfAnXMLFile.xml D:\site\datafiles\test\BigMotherOfAnXMLFile.xml
    close
    exit

I can provide the source code to my C# app if you would like. I'll have to do that by separate post. Just let me know.
