In this example, we insert a Shape control and two command buttons. 5.3 ConstantsД¬onstants are different from variables in the sense that their values do notД¬hange during the running of the program. Most variables created inside a procedure are discarded by Visual Basic when the procedure is finished, static keyword preserves the value of a variable even after the procedure is terminated.В Public is the keyword that declares a global variable, which means it can be used by all the procedures and modules of the whole program. The Static keyword declares a variable that is being used multiple times, even after a procedure has been terminated. However, Private is rarely used, we normally use Dim to declare a local variable. Private declares a local variable or a variable that is local to a procedure or module. The above keywords indicate the scope of the declaration. Three other keywords are private ,static and public. Other than using the Dim keyword to declare the data, you can also use other keywords to declare the data. Where n defines the number of characters the string can hold. However, for the fixed-length string, you have to use the syntax as shown For the variable-length string, just use the same format as example 5.1ДЄbove. Types, one for the variable-length stringВ and another for the fixed-length A variant is data type that can hold any type of data.ДЇor string declaration, there are two possible VB willautomatically declare the variable as a Variant. Unlike other programming languages, Visual Basic actually doesn't require you to specifically declare a variable before it's used.

If you want to declare more variables, you can declare them in separate lines or you may also combine more in one line, separatingДЄs DataType1, VariableName2 As DataType2, VariableName3 As DataType3 Example 5.1Дim password As String, yourName As String, firstnum As Integer You can use any variable to hold any data, but different types of variables are designed to work efficiently with different data types.

In the general section of the codes' windows using the Dim statement. In Visual Basic, it is a good practice to declare the variablesД«efore using them by assigning names and data types. Table 5.4: Examples of Valid and Invalid Variable Names

Cannot repeat names within the same level of scope.Д®xamples of valid and invalid variable names are.

Cannot use exclamation mark (!), or the characters &, $, #.

The following are the rules when naming the Variable in Visual Basic, you have to follow a set of rules. Like the mail boxes, each variable must be given a name. In term of VB, variables are areas allocated by the computer memory to The contents of the variables changes every now and then, just like the mailД«oxes. Variables are like mail boxes in the post office. Strings canД¬ontain any characters, including numbers. Within two quotations and date and time literals within two # sign. These data types summarized in Table 5.1Дata addition, we need to enclose string literals Lastly, if even more precision is required to performД¬alculations that involve many decimal points, we can use the decimal data Precision calculation need to use Single and Double decision data types, theyДЄre also called floating point numbers. In Visual Basic, numeric data are divided into 7 types, depending on the range of values they canД¬alculations that only involve round figuresД¬an use Integer or Long integer in the computation. Numeric data types are types of data that consist of numbers that can be computed mathematically with standard operators.Д®xamples of numeric data types are height, weight, share values, the price of goods, monthly bills, fees and others. Types, they are the numeric data types and the non-numeric data types. VB6 classifies the information mentioned above into two major data

To manage when we need to write the code involving those data. VB divides data into different types so that they are easier Similarly, in Visual Basic, we have to deal with all sorts of data, some can be mathematically calculated while some are in the form Handle data such as names, addresses, money, date, stock quotes, statistics and

We come across all kinds of data in our daily life.
