First off, I'm new to WinSCP, I've only been working with it 2 days but have digested a lot of information that has been helpful but am now stuck.
I have developed a VB.NET Windows Service running under XP. I need to transfer files to a secured FTP site so have downloaded your VB.NET Assembly. I initially downloaded 4.3.8 of WinSCP but when I first attempted to connect with the VB.NET it told me the versions did not match so I downloaded and installed 5.0.7 of WinSCP. I'm able to connect to my server with the GUI and transfer files. Each time I connect I get a warning about connecting to the server but then it connects and I can transfer files. From VB.NET I get the message "Connection has been unexpectedly closed. Server sent command exit status 0.". I viewed your error list but nothing seemed to help.
Next I produced a log using Session.SessionLogPath and it appears that it's expecting a Password? Why when I've provided it with a Host Key? I've used the GUI so I know the username is correct and connected leaving the password blank. I'll post my code first (with security info removed) and then the log.
Thanks in advance.
Dim sessionOptions As New SessionOptions
.Protocol = Protocol.Sftp
.HostName = SFTPServerName
.UserName = Username
.Password = ""
.SshHostKey = SFTPServerKey
Using session As Session = New Session
session.SessionLogPath = OutputFolder & "WinSCP.log"
' Upload files
Dim transferOptions As New TransferOptions
transferOptions.TransferMode = TransferMode.Binary
Dim transferResult As TransferOperationResult
transferResult = session.PutFiles(FileToBeSent, SFTPServerDir, False, transferOptions)
' Throw on any error
' Print results
Dim transfer As TransferEventArgs
For Each transfer In transferResult.Transfers
bErr = util.SaveTextToFile(Now().ToString & " Transferred: " & FileToBeSent & ".", OutputFolder & "Transactions.log", ErrInfo)

Maybe you are confuing a host key fingerpring with a private key path. Hostkey is not used for authentication.

Thanks for the advice. I added the SshPrivateKey property and it's now transferring data.
