VS 2010 Need Help about user input

Hello guys, I'm super new to this site and said "heck i will sign up and maybe get some help and become active"

I am working on a tutorial application for windows c++ using visual basic

In order for me to do that, i must show examples then after they read the chapter i want to quiz them,

I want it so the user has the ability to INPUT text/code and i want it to check the code to see if it is right in order to go on to the next section..

Has anyone gotten ideas on how i would go about doing this?

I set up a forum and they can read it, I already added a button that says "go back" or "Proceed Forward" When a user clicks on the "Proceed Forward" box i want it to come up with a box that makes the user have the ability to input code, If the code is correct i want it to move forward in the application, If not i want it to close the input window and go back to the tutorial page..

Is this possible and how on the earth would i go about doing this?

Many Thanks
