cguan_77 has written the right code for this. Use his code in this way : -

Private Sub Command1_Click()
Dim txturl As String
txturl = "http://www.google.com"
Shell "C:\Program Files\Internet Explorer\IExplore.exe " & txturl, vbMaximizedFocus
End Sub

Your right (provided you use MSIE for all surfing)
My post would open the users preferred default browser instead.
That is the only difference.
