Programming texts have featured a "Hello World" program since the granddaddy of them all in 1978. The developers of the C programming language (Kernighan and Ritchie) introduced their new language to the world in a book titled "THE C PROGRAMMING LANGUAGE." The opening page of this book showed a C program that simply prints "hello, world".
Our text upholds the tradition by including a pretty traditional "Hello World" as the first example of Chapter 3. I have to admit that I'm guilty as well. Most of the other tutorials I have written for About Visual Basic also include a "Hello World" example.
"Hello World" is out of place this time around, however. The Lucky Seven program from Chapter 2 is more advanced so if you feel like skipping anything in the book, skip this. (But if you feel like you need something easier to get the concepts completely straight in your mind, then this is what you're looking for!)
The next program is a very similar program but it uses a much more interesting control than a textbox or a button - the DateTimePicker control. One thing this control does is help you see just how much a control can do for you. This one does a lot!
Before getting started, make sure you understand the definitions starting on page 75. Learning the language is half the job in most things. The "Terminology" here is a really good list. As you write the next program, see if you can apply each of the terms in this list.
