How to run Bat file in VB.net

I suspect you intended to post this question on the VB.Net rather than the SQL Server 2005 forum but, as I think I know the answer, I'll answer it anyway :)

Try this code with the path of your .bat file:

Imports System
Imports System.Diagnostics

Module Test

     Sub Main()
      
       Dim proc As New Process()
       Dim batFilePath As String = "C:\somefolder\somefile.bat" 
       proc.Start(batFilePath)

     End Sub

End Module
