First add a button
Then double click on it

Add this code below for the simple version.

Now to add a title to you message box do this.

This adds a title to the message box.

This is very easy but if you need more help just lemme know.

Okay yeah I could see someone who actually knows what C# is thinking that was easy, but I don't know, I've never done anything with C or C#, so I don't have a clue what it is. I don't have a clue on "double-click that button". What program? I need help.

OK, so the program you use is Microsoft C# 2005 Express Edition. When you start a new project there is a place on the left side called "Toolbox" and there is something in there called "button". You drag and drop the button onto your application. Once you did that you double click on the button you just added. If you still need more help let me know.

Ahh very cool thanks Blackbelt!~

If this follows the guidelines of C++ Use
If(IDNO != NULL){
goto [put label here];
}
That way when they click no it redirects it to the label you set up before the message box.
