Invalid Pointer

[Krammig]

Firstly, thank you for project. I'm using an HP Laptop with a Validity inbuilt sensor supporting WBF

Starting the WindowsFormsTest

Found 1 units Using unit id: 1 Device instance id: USB\VID_138A&PID_0018\3C7BAA7EB303 Using database: bc7263c3-a7ce-49f3-8ebf-d47d74863cc6 Session opened: 14293

Clicking the Locate Sensor button - Locating sensor....

and that is all that happens, just sits there. So I swiped my finger and then it showed - Sensor located: unit id 1

Now I click Identify - Identifying user... WinBioIdentify failed: InvalidArguments

If I start again and get to Enroll instead - Beginning enrollment of RhIndexFinger: WinBioEnrollBegin failed: InvalidPointer

The Cancel button does not seem to cancel the app.

thanks

This project is mainly a .NET wrapper for the unmanaged WinBio library. The test applications are just a proof of concept and nothing more.
