Module 6

Controlling Program Flow

In this chapter, you learned how to use the If control structure together with the 
comparison operators to control program flow. 
 In section 7.1, you learned how to use the conditional operators in VB2010 such 
as =, <,>, >=, <= and <>.
 In section 7.2, you learned how to use the logical operators And, Or, Xor and 
Not. 
 In section 7.3, you learned how to implement three types of If control structure, 
i.e. If...Then, If...Then...Else and If...Then...ElseIf


Select Case Control Structure

In this chapter, you learned how to control program flow using the Select Case control 
structure. You also learned how to write code for the practical usage of the Select Case 
control structure, such as the program that processed examination marks.

Looping

Summary 
 In section 9.1, you learned how to write code for the For...Next loop. The loop 
stops when a condition is met. You also learned how to use Exit For to exit 
the loop.
 In section 9.2, you learned how to write code for the Do loop procedure. You 
also learned how to use Exit Do to exit the loop. 
 In section 9.3, you learned how to write code for the While...End While loop. 
You also learned that the loop stops when a condition is met.

Module 3

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.

A function is similar to a normal procedure but the main purpose of the function is to accept  a certain input and return a value, which is passed on to the main program to finish the  execution. There are two types of functions, the built-in functions (or internal functions) and  the functions created by the programmers.  The general format of a function is   FunctionName (arguments)  The arguments are values that are passed on to the function.  In this Chapter, we are going to learn two very basic but useful internal functions of Visual  Basic, i.e. the MsgBox( ) and InputBox ( ) functions.  Summary  You learned that a function is a procedure that accepts an input and returns a value,  which is passed on to the main program to finish the execution. You also learned  that the format of a function is FunctionName (arguments).  In section 10.1, you learned to use the Msg () function to produce a popup  message box to prompt the user to click on a button to continue the  execution.
