My question is how to setup to load the EventHandlers and how to obtain the fingerprint in a bitmap image. I have searched for examples, but was unable to find any descriptive one.

However, IВґm not interested in using the GUI version. I have read the API documentation and saw the sample program they provided.

I'm using a DigitalPersona reader UareU 4500. I'm new to coding with biometric sensors and DLLs in C#.
