Get the output of a shell Command in VB.net

by

You won’t be able to capture the output from Shell.

You will need to change this to a process and you will need to capture the the Standard Output (and possibly Error) streams from the process.

Here is an example:

        Dim oProcess As New Process()
        Dim oStartInfo As New ProcessStartInfo("ApplicationName.exe", "arguments")
        oStartInfo.UseShellExecute = False
        oStartInfo.RedirectStandardOutput = True
        oProcess.StartInfo = oStartInfo
        oProcess.Start()

        Dim sOutput As String
        Using oStreamReader As System.IO.StreamReader = oProcess.StandardOutput
            sOutput = oStreamReader.ReadToEnd()
        End Using
        Console.WriteLine(sOutput)

To get the standard error:

'Add this next to standard output redirect
 oStartInfo.RedirectStandardError = True

'Add this below
Using oStreamReader As System.IO.StreamReader = checkOut.StandardError
        sOutput = oStreamReader.ReadToEnd()
End Using
