C++ C# Visual Basic - GURU

I have an application written in VB6 that uses Biometric Fingerprint scanners. Works fine. It uses Native code and Drivers for the various devices. WBF (Windows Biometric Framework) is a platform developed by Microsoft. I want to add WBF to my app so I can use more recent WBF type devices. The CODE is already available a C# and C++ and just needs some modification. a) create a working scanner DLL using existing WBF Code to show the working process. This code already exists and I have used it here successfully. Just need to add ; i) Capture - WinBioCaptureSample [login to view URL](v=vs.85).aspx ii) Compare - two scans to see if they Match b) create a DLL (perhaps a wrapper) that interfaces with (a) and WinBio or other code I have here so it talks to my VB code The Objective is for my app to be able to ; i) send a Call to the DLL Wrapper of WinBio to get the user to Scan their finger and pass that data back to my app ii) convert the data in WINBIO_BIR data structure to an Image. I have a link that explains how to do this - Easy ii) In the Warapper DLL expose the other commands of WinBio such as Locate, Attach, Detach etc etc - Easy thanks
