How can I detect en get acces to the internal GPS of my WT8 Encore tablet (windows 8.1) with a Visual Basic-app. My existing app detects and handles an external GPS receiver, but cannot see the internal GPS.
I found a web-based object that is invoked by a javascript and that works fine with the internal GPS sensor. See: http://msdn.microsoft.com/en-us/library/windows/desktop/dd317709(v=vs.85).aspx. But using a simpel webbrowser in my application to get the data from does not work because it gives no button to accept using location-data like in web-based applications.

Probably you mean VB.NET, not "VB", right?

Yes that's right. See also my comment under the solution from Yvan Rodrigues.

There are two common ways that GPS devices (internal or external) interface with wintel computers.

Most connect to a COM port (RS232C), either real or virtual. With these devices you can connect with a terminal application (or read and write the COM port in your case). The GPS sends strings out the port that follow the NEMA 0183 standard. Here is an example in VB.NET: Mapping with a GPS and VB.NET[^]

Other devices do not use a COM port, but some other other proprietary means of communication. In this case the manufacturer includes a driver that one of the Windows location APIs can use.

In your case they did the latter. I think you will find this thread useful.[^]
