Question

I’m using System.IO.File.Copy to copy a file to c$ on a remote server. I need to specify username/password for the connection. Is there a simple way to do this? I had hoped that System.IO.File.Copy would accept credentials as an argument but it doesn’t. How can I do this?

Answer 1

Absolute simplest thing to do is to add this routine to your code then call it right before your File.Copy:

Private Sub Open_Remote_Connection(ByVal strComputer As String, ByVal strUsername As String, ByVal strPassword As String)
    '//====================================================================================
    '//using NET USE to open a connection to the remote computer
    '//with the specified credentials. if we dont do this first, File.Copy will fail
    '//====================================================================================
    Dim ProcessStartInfo As New System.Diagnostics.ProcessStartInfo
    ProcessStartInfo.FileName = "net"
    ProcessStartInfo.Arguments = "use \\" & strComputer & "\c$ /USER:" & strUsername & " " & strPassword
    ProcessStartInfo.WindowStyle = ProcessWindowStyle.Hidden
    System.Diagnostics.Process.Start(ProcessStartInfo)

    '//============================================================================
    '//wait 2 seconds to let the above command complete or the copy will still fail
    '//============================================================================
    System.Threading.Thread.Sleep(2000)
End Sub
