I'm looking forward to reading and adding more to the community here. I've created a text based rpg. Next semester we are learning Visual Basic. I'm on winter break and I would like to get a head start on my learning. I've been working on creating some forms and message boxes. What is throwing me off, is that I have a good feel for doing coding so that I get functionality the will produce effects in a console. Coding the forms is a bit confusing for me. Is this something that others have run into? Is their some good primers for VB? I don't have my text books yet.

I am doing an application where a person can enter a string in a text box. The application reverses it. That all works fine.
I am trying to set up an if statement where if nothing is entered in the box and Submit is clicked, a message box pops up and tells you that the box can't be empty. The message box pops up fine but when the user clicks on ok to close the box, another blank box pops up. How do I get rid of the blank message box?

okay so I have a simple code to generate card picks and store them in numbers except no two cards can be the same so my checkIf functions checks it against the current list. Also no four a values can be the same since there are only 4 cards of the same type in a standard deck. Now the problem I am having is that when I run my code I only get two message boxes when I believe I should be getting 30 - (15 a's and 15 b's).[code]
