Reading Network Drive

[ddddd13]

I am trying to read a file from a network drive I have setup on another computer. I have the following code on a button.

   Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Using sr As New System.IO.StreamReader("Z:\Files\MachUpdate.txt")
            While Not sr.EndOfStream
                MachUpdate.Add(sr.ReadLine())
            End While
        End Using
        RichTextBox2.Text = MachUpdate(1)

I am quite certain something is wrong with the path Z:\Files\MachUpdate.txt because I have the same file on the computer running advanced HMI c:\Files\MachUpdate.txt and it too bombs out with system I/O file not found. Any idea what my path should be?

Thanks,
Dave

I never trust a mapped drive because they tend to lose connection and not reconnect. I always use the full UNC path such as:

\\servername\path\filename

So, I have changed the path to
  Using sr As New System.IO.StreamReader("\\DAVE-PC\Z:\Files\MachUpdate.txt")
or
 Using sr As New System.IO.StreamReader("\\(DAVE-PC)\Z:\Files\MachUpdate.txt")
I still get an alarm.
or
Using sr As New System.IO.StreamReader("(\\(DAVE-PC)\Z:\Files\MachUpdate.txt")

System not supported exception: The given path's format is not supported

The Z: would no longer be used unless it is a directory.

If you put the path in Windows Explorer, does it show anything?

Is your remote PC setup as a shared directory? Is the firewall turned off?

Archie;

This is weird as shit.

This is the way it has to be entered.

 Using sr As New System.IO.StreamReader("\\DAVE-PC\Network folder\Files\MachUpdate.txt.txt"

Without the double txt.txt it will not work

Does that make sense to you?

You have your file explorer set to hide extensions, and your file name is "MachUpdate.txt", with the extension txt. At least this is what I experienced before with similar cases.
