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.

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...

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...

Managing VB2010 Data   Getting to know various data types in Visual Basic 2010   Assigning values to the variables   Getting to know various arithmetic operators in Visual Basic 2010  In our daily life we come across many types of data. For example, we need to handle data  such as names, addresses, money, dates, stock quotes, statistics and more everyday.  Similarly, in Visual Basic 2010, we have to deal with all sorts of data; some are numeric in  natrure while some are in the form of text or other forms. VB2010 divides data into different  types so that it is easier to manage when we need to write the code involving those data.  4.1 Visual Basic 2010 Data Types Visual Basic classifies the information mentioned above into two major data types; namely  the numeric data types and the non-numeric data types.  4.1.1 Numeric Data Types  Numeric data types are types of data that consist of numbers, which you can compute  the...
