This VI uses a Microsoft Web Browser ActiveX container to create a simple Web Browser in LabVIEW. You type the URL in a location input and LabVIEW navigates to it. You can navigate back, forward, reload, and search, and the VI keeps a running history list that you can use in a run-time menu.
As of LabVIEW 7.1 a more simple example can be found in LabVIEW's Example Finder under Communicating with External Applications»ActiveX»General»ActiveX Event callback for IE.
Admin note: You can find thelatest example here: C:\<Program Files>\National Instruments\<LabVIEW Version>\examples\Connectivity\ActiveX\ActiveX Event Callback.vi
