Run .Net Desktop application on iPad
With regard to your question, I believe iPad is not compatible with applications that developed by MS Visual Basic. There are several apps in Apps Store that you can download exclusively for Apple iPad, iPhone and iTouch. Also, the applications that can run to iPad are programs that are built-in in C/C++/Objective C. Also, you can download those applications through iTunes Store.
You can access Apps Store on your iPad by tapping on "Apps Store" on your iPad's home screen. From there you can download either Paid/Purchased Applications or Free Applications.
Hope this might help you. =)
