Experienced C# and VB6 developer - WBF (Windows Biometric Framework - Microsoft)

I have a C# project that uses the WBF (Windows Biometric Framework) and Microsofts WinBio code / library. This project requires a simple bit of code to be added and modified based on Microsoft docs in the links below. A simple task for a good C# person who also knows VB6. Why VB6 ? because the WinBio dll that is written in C# will pass data to the VB6 app. I can provide the current C# code and the VB6 code. Ideally you will have a laptop with a built in finger scanner so you can test easily - but - I am happy to do the testing here live with you to help code the project.

Using WinBioIndetify - that "does" return an error correctly. [login to view URL] HRESULT WinBioIdentify( WINBIO_SESSION_HANDLE SessionHandle, WINBIO_UNIT_ID *UnitId, WINBIO_IDENTITY *Identity, WINBIO_BIOMETRIC_SUBTYPE *SubFactor, WINBIO_REJECT_DETAIL *RejectDetail ); The Question is then why is the WinBioCapture method not working correctly. This project is to ; a) get the error code back (rejectDetail) from WinBioCapture. As I said it works with WinBioIdentify, so theoretically it should also work in Capture Example; WINBIO_FP_POOR_QUALITY WINBIO_FP_TOO_SKEWED WINBIO_FP_TOO_SHORT WINBIO_FP_MERGE_FAILURE b) Update "DeviceInfo" to return correct information. _imageHeight _imageWidth _imageSize Thanks
