Linking database with vb.net?

Hi all,

I am here again with another problem.
I have successfully created my design for the mcq test project *its still in the design stage*



Anyhow I need to move on to the part where I will have to check the answers from the radioboxes. The answers for these questions are stored in pdf files such as this.



So can you guys suggest me ways to check these amswers. I know I am a beginner!
Thanks alot anyways!
