Shell and the Windows API CreateProcess() are for starting executable files. If you're loading a document/file then these are handled by ShellExecute() and can be initiated in .NET using the Process.UseShellExecute property:

Private Function ShellExecute(ByVal File As String) As Boolean
  Dim myProcess As New Process
  myProcess.StartInfo.FileName = File
  myProcess.StartInfo.UseShellExecute = True
  myProcess.StartInfo.RedirectStandardOutput = False
  myProcess.Start()
  myProcess.Dispose()
End Function
