Notice: Coding between compilers may vary. For example, "messagebox.show()" is the message prompt in Express Edition whereas "msgbox()" is the prompt in Visual Basic 6.0. All code in this guide is Express Edition.

In part on, we learned the basics of Visual Basic, including Strings and Integers. Once you feel comfortable with it, you can move onto this part. As said before, the beginning part of learning is the hardest. Since this is still the beginning, you may struggle on some things. Don't worry though; things are repeated numerous times.

First off, we are going to learn how do use an Input Box, a box where you can enter text and record it. To do that, we need to use another Dim. For this particular case, we need to use the Dim Object command. Dim Object, when declared, tells the compiler to store an object into the memory. Objects can be many types of forms or message boxes--in this case, an input box.



The variable "box" is now an object. So we need to tell the compiler what object it is. We want Mr. box to be an input box, so let's say so.



The "box = InputBox" defines it. The ("") is simply text. You can add variables in there by simply removing the quotes. When you run this, you'll see something like this:



This is nice, but it doesn't do anything when you click OK. We're going to add a textbox afterwards saying what the user typed in the box. How do we do that? Simple.



When the data is entered, it is stored in the variable "box". Objects, such as "box", can store both alphabetical (strings) and numerical (integers) characters. After the user has entered a value, the message "Your name is " will show up. Then, the value "box" (AKA: The value the user entered" will show up, following the space at the end of the message "Your name is ". Easy? Try understanding this one:



When you want to compare certain information, you use Signs, symbols that represent greater then, less then, and equal. Actually, there is more then that. This table shows the signs and their meaning.



Tip: If you confuse greater and less then signs, think of their looks. The < sign looks like an "L" if you turn it, which means "Less then".

We are also going to learn Branching, coding comparing multiple data and varying on their conditions. Branching must always start with "If" and end with "End If" There must also be an "Else" condition in the middle. Most compilers, however, already add the "End If" and "Else".



Branching is like asking a question. This case, it is saying "Is the number 5 equal to the number 5?" Of course, this is true. So, the value under "If 5 = 5 Then" is what happens when this is true. The value under "Else" is what happens when it's incorrect. So, what'll show up here? Easy.

Read through the following code and think to yourself what it does.



This code is simple. If you enter a number equal to 10 or higher, the message "OK, you're old enough" will appear. However, if you say the number 9 or below (negatives count), then the other message will appear.

Let's now learn comments. These helper’s help--and a lot. Comments are side-notes added into the script that do nothing but tell you a note. They are NOT displayed in the program itself. Here is how you do a comment:



Everything displayed on the line following the ' is a comment. You can use them to remind you of things. Pretty easy.

I'm coming to a conclusion on this tutorial. But I'll bring you one nice tip; check over your work. You can make pretty stupid mistakes that you miss. Some compilers will find them for you, but be cautious.



If you have any questions, just post them. I'll try to answer as many as I can. Please remember that I'm not an expert at this; so don't ask me to build an operating system.

gooooooog!
