3.1 Understanding Event Driven Programming VB2010 is an object oriented and event driven programming language. In fact, all windows  applications are event driven. Event driven means the user decides what to do with the  program, whether he or she wants to click the command button, enter text in a text box, or  close the application and more. An event is related to an object, it is an incident that  happens to the object due to the action of the user, such as a click or pressing a key on the  keyboard. A class contains events as it creates instant of a class or an object Summary   In section 3.1, you learned the concept of event driven programming.   In section 3.2, you learned how to write a simple code for an event procedure,  including the usage of MsgBox().   In section 3.3, you learned how to create a multiplication program.   In section 3.4, you learned how to write a program to add some items to a list  box.

Computers can perform mathematical calculations much faster than human beings.  However, the computer itself will not be able to perform any mathematical calculations  without receiving instructions from the programmer. In VB2010, we can write code to  instruct the computer to perform mathematical calculations such as addition, subtraction,  multiplication, division and other kinds of arithmetic operations. In order for VB2010 to  carry out arithmetic calculations, we need to write code that involves the use of various  arithmetic operators. The VB2010 arithmetic operators are very similar to the normal  arithmetic operators, only with slight variations. The plus and minus operators are the  same while the multiplication operator use the * symbol and the division operator use the /  symbol. The list of VB2010 arithmetic operators are shown in table 5.1 below: Summary  In this chapter, you learned how to use various mathematical operators in Visual  Basic 2010 in writing code for mathem
