Hi,

I want to display directory information for the user's LOCAL computer via a web application.  I wrote the following code...

--------------------------------------------------------------------------------------------------------
        Dim dir As String = "C:\"
        Dim files, dirs As String()
        Dim fileName, directoryName As String

        If Directory.Exists(dir) Then

            dirs = Directory.GetDirectories(dir)
            files = Directory.GetFiles(dir)

            For Each fileName In files
                lblFiles.Text += fileName & ", "
            Next

            For Each directoryName In dirs
                lblDirectories.Text += directoryName & ", "
            Next

        Else

            lblError.Text = "Invalid directory: " & dir

        End If
--------------------------------------------------------------------------------------------------------

This lists the files on the web server.  Is there any way to list the local files on a user's computer?

In short, no this is a security risk

I'm thinking you'll need to use a client-side script (VBScript, JavaScript, etc) to do this.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/script56/html/jsobjFileSystem.asp


However, I also think I remeber MS patching IE so you couldn't read the file system via web-script any more (spyware/hackers)

By default, most browsers would have security settings preventing a webpage from doing this, as Aeros said it's a security risk.  An ActiveX component might be able to do this.

Otherwise, i would abandon this as an idea as a lot of anti-virus software and anti-ad/spyware software will block any client scripts that may attempt to access the file system.  They would probably assume the script is trying to exploit the system.

Hope this helps.

I agree with AerosSaga and pillbug22.  An answer that states that a reasonable solution is not possible or unlikely, although not what the person posing the question wanted, is still an answer!
