Hello,
does anyone have a code sample of cancel transfer method?
The help file comments that this method generally called from a separate thread but when i call the cancel transfer method the application not respond.

Thanks.

Can you post the log file that is produced?

Normally a separate thread would be needed to cancel the transfer as the current thread will be blocking during the transfer

It could be a threading problem, i.e. the main thread is downloading, therefore the cancel gets blocked as it is also in the main thread.

This is the log produced:

Do you have an example or any ideas?
Thanks!

But i call CancelTransfer method in a different thread that the main thread.

Code:

Private cancelarT As Thread
cancelarT = New Thread(New ThreadStart(AddressOf modmain.Cancelar))
cancelarT.Start()

Private Sub Cancelar()
ftp.CancelTransfer()
End Sub

Doesn't exists any example of this?

Thanks

We'll put a test case together for the next release.

But i call CancelTransfer method in a different thread that the main thread.

Code:

Private cancelarT As Thread
cancelarT = New Thread(New ThreadStart(AddressOf modmain.Cancelar))
cancelarT.Start()

Private Sub Cancelar()
ftp.CancelTransfer()
End Sub

Doesn't exists any example of this?

Hello,

I need a solution, too. Where can I download the fixed version?
You just have 1.1.9 on your page.

Best regards,
Rainer
