'Write the temp file
sTmpFile = System.IO.Path.GetTempFileName()
sw = New IO.StreamWriter(sTmpFile, False)
sw.Write(Me.BookingRow.sCRSRecord)
sw.Close()

'Launch the external application
Dim myProcess As System.Diagnostics.Process = New System.Diagnostics.Process()
myProcess.StartInfo.FileName = "notepad.exe"
myProcess.StartInfo.Arguments = sTmpFile
myProcess.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal myProcess.Start()
