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 5.1Ībove. Types, one for the variable-length string and another for the fixed-length A variant is data type that can hold any type of data.įor string declaration, there are two possible VB willautomatically declare the variable as a Variant.

If you want to declare more variables, you can declare them in separate lines or you may also combine more in one line, separatingĪs DataType1, VariableName2 As DataType2, VariableName3 As DataType3 Example 5.1ĭim 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 variablesīefore using them by assigning names and data types. Table 5.4: Examples of Valid and Invalid Variable Names
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.
