Interacting with attendance biometric device using OCX dll

Question

I am using visual studio 2012. I am trying to interact with a biometric attendance device through a desktop application via ip address. I added the necessary dll and ocx files to the reference folder of the project. I created the object of 'SB100PCLib' quite easily, but when I try to execute its functions, I get this run time error

Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

As I am quite new dealing with third party dll, is there any extra step to perform? How to get rid of the error?
