VBScript arrays are variables that increase script flexibility. VBScript is a Microsoft scripting language used for client-side scripts and server-side scripting. Arrays can have up to 60 dimensions, with static and dynamic types. VBScript offers functions and loop statements for common tasks, such as exporting data and connecting to databases.
Arrays in VBScript are functions that create specific types of variables that can increase the flexibility of a script. Just as they are used in algebra, variables used in programming are placeholders for values. The algebraic expression x + y = z is an example of the use of variables. In this example, the x can be set to equal any number. Similarly, when you use an array, the value of the variable can change and you don’t need to hardcode it.
VBScript is a Microsoft® scripting language related to Visual Basic and Active Scripting, originally called ActiveX. Web developers can use VBScript in client-side scripts for the Internet Explorer® browser. It can also be used for server side scripting in an ASP.Net environment. Windows system administrators can use VBScript because it can be used to interact with the Windows Component Object Model (COM) and to automate some system maintenance tasks.
This scripting language allows you to use up to 60 positions, or dimensions, in its arrays. Arrays in VBScript start with the number 0 for element indexing, which indicates the position within the array. The 0 will indicate the first position, the number 1 will indicate the second position, and so on.
There are two types of arrays in VBScript. The first type is a static array. This is the simplest type. When using this array, the programmer defines the index size, which is the maximum number of elements, of the foreground array and it will not change.
A more flexible and useful type of array is the dynamic array. A dynamic array allows you to change the size of the array while the script is running. An extension of dynamic array is a multidimensional array. With this convention, a programmer can establish an array with two or more dimensions.
Regardless of type, VBScript provides a number of functions for use with arrays. These functions facilitate some common tasks, such as joining or dividing data into arrays. VBScript also offers a loop statement that can be used to step through each element in an array.
Some common programming tasks can use the loop function. Arrays in VBScript can be used to export data from one file to another. A script can take data entered into an HTML form, store it in arrays, and then use that data elsewhere on a website. Another useful task involves writing a script to connect to a database and then using the array function to display the data on a web page or other screen.
