WinBioDeleteTemplate function Returns 80098002?

Question

i am programming in c# to develop WBF FMA(Windows Biometric Framework Fingerprint management application).

i am using WinBioDeleteTemplate() function to delete a template.it works fine most times.

But sometimes it returns 80098002 returncode.

After i restart the system,it works fine.

So,what is an issue? How to i resolve this?

Answer 1

this error suggests that The unit ID number does not correspond to a valid biometric device. You are possibly passing an invalid unit id to WinBioDeleteTemplate() and that is why you are receiving this error.
