reading unmanaged .dll

[.paul.]

i tried this code to read an unmanaged .dll:

Dim result As DialogResult

        result = ofd1.ShowDialog()

        If result = Windows.Forms.DialogResult.OK Then
            ''
            '' for this example ofd1.filename = "c:\windows\system32\wininet.dll"
            ''
            System.Diagnostics.Process.Start("C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin\TlbImp.exe " _
& ofd1.FileName & "/out:" & My.Application.Info.DirectoryPath & "\myTest.dll")
            Threading.Thread.Sleep(5000)
System.Diagnostics.Process.Start("C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin\ildasm.exe myTest.dll /out:myTest.il")
        End If

but it doesn't work. error is - file not found.
what am i doing wrong?
