Nearly all objects (labels, textboxes, etc.) have a "Hyperlink Address" property. Put the full URL in that property and clicking on that object will launch your default browser and go to the URL specified.
Public ie as InternetExplorer
Private Sub cmdButton_Click()
Set ie = CreateObject("InternetExplorer.Application")
ie.Navigate "http://visualbasic.about.com"
End Sub
Using ie.Navigate2 in this code will open the website in a new IE window. If you are trying to open the website on one of your forms, let me know I'll post how to do that.
