Martin, I got the output from the log files and the problem seems to be the time out variable that is set to 0 -timeout=0 even though I set it up as .Timeout = New TimeSpan(26000) Do you have any ideas how I can change this ?

Set the .Timeout to a reasonable number. TimeSpan(26000) is indeed 0, when rounded to whole seconds.

Try setting Session.SessionLogFile and Session.DebugLogFile and attach the logs.

Thank you
I'll try that and I will post the results

[quote="martin"]Did you try to step through your code? Sorry, but we cannot debug your code for you.[/quote]

Yeah I tried to debug it. I know you cannot debug it. I just want to know if you have any ideas what it can be. I tried to research my problem I haven't found my problem listed.

I tried to add some break point in visual studio and when it times out is like it wasn't running the code anymore. it doesn't take any of my break point listed.

for this reason, It's impossible for me to find what it's causing the problem.

when I work with small files(doesn't matter the size, it just matter of time) it works perfectly. The problem is when the tool is working for x amount of time and it times out. So, when that happens it just skips any process that comes after downloading the file. Also, the progress bar doesn't work anymore when it times out.

Did you try to step through your code? Sorry, but we cannot debug your code for you.

Greetings,

I'm developing a SFTP client, I'm connecting and downloading and everything. the problem comes with I'm downloading a big file >10Gb. I get a "A first chance exception of type 'System.TimeoutException' occurred in WinSCPnet.dll" the program keeps downloading with the filepart files. it downloads the complete folder from the server, the problem is that I have some other method or functions after the download and it's not getting there.

So, I don't Understand why after a time out it resumes but it doesn't run all the code.

can somebody explain me what is happening here?

Part of my code
Try
' Set up session options
Select Case opt

Case 1 ' Connect
AddHandler session.FileTransferProgress, AddressOf SessionFileTransferProgress

.UserName = "xxx"

.SshPrivateKeyPath = "xxxx"
.Timeout = New TimeSpan(26000)
.AddRawSettings("FSProtocol", "x")
.AddRawSettings("ProxyMethod", "x")
.AddRawSettings("ProxyHost", "xxxx")
.AddRawSettings("ProxyPort", "x")
End With


session.Open(sessionOptions)
MsgBox("Connection succesful", MsgBoxStyle.OkOnly)
flag = True
Case 6 ' download
Form1.ProgressBar1.Visible = True
Form1.lbldown.Visible = True
Form1.Label4.Visible = True
