[2005] Printing File To Printer

Hey,

Does anyone know how to send a file directly to the printer, no matter what the file type is? I have a set of files currently that I double click on and they are sent directly to the printer. Or I am asked to define the file type. Can this be done in VB. Either printing direct to the printer, or performing a double click type scenario on the file through VB?

This code to work needs the file type to associated.
In this example you need to have Excel or Office installed.

Code:

---

        Dim strFile As String= "c:\test.xls"
        Dim objProcess As New System.Diagnostics.ProcessStartInfo

            With objProcess
                .FileName = strFile
                .WindowStyle = ProcessWindowStyle.Hidden
                .Verb = "print"
                .CreateNoWindow = True
                .UseShellExecute = True
            End With
            Try
                System.Diagnostics.Process.Start(objProcess)
            Catch ex As Exception
                MessageBox.Show(ex.Message)
            End Try
