VBScript in Internet Explorer
Here are simple steps to turn on or turn off VBScript in your Internet Explorer:
 Follow Tools -> Internet Options from the menu
 Select Security tab from the dialog box
 Click the Custom Level button
 Scroll down till you find Scripting option
 Select Enable radio button under Active scripting
 Finally click OK and come out
To disable VBScript support in your Internet Explorer, you need to select Disable radio button under Active scripting.

VBScript Placement in HTML File
There is a flexibility given to include VBScript code anywhere in an HTML document. But the most preferred way to include VBScript in your HTML file is as follows:
 Script in <head>…</head> section.
 Script in <body>…</body> section.
 Script in <body>…</body> and <head>…</head> sections.
 Script in an external file and then include in <head>…</head> section.
In the following section, we will see how we can put VBScript in different ways:
VBScript in <head>…</head> section
If you want to have a script run on some event, such as when a user clicks somewhere, then you will place that script in the head as follows:
<html>
<head>
<script type=”text/Vbscript”>
<!–
Function sayHello()
Msgbox(“Hello World”)
End Function
//–>
</script>
</head>
<body>
<input type=”button” onclick=”sayHello()” value=”Say Hello” />
</body>
</html> 4. VBScript– Placements

It will produce the following result: A button with the name SayHello. Upon clicking on the Button, the message box is displayed to the user with the message “Hello World”.
VBScript in <body>…</body> section
If you need a script to run as the page loads so that the script generates content in the page, the script goes in the <body> portion of the document. In this case, you would not have any function defined using VBScript:
<html>
<head>
</head>
<body>
<script type=”text/vbscript”>
<!–
document.write(“Hello World”)
//–>
</script>
<p>This is web page body </p>
</body>
</html>
It will produce the following result:
Hello World
This is web page body
VBScript in <body> and <head> Sections
You can put your VBScript code in <head> and <body> section altogether as follows:
<html>
<head>
<script type=”text/vbscript”>
<!–
Function sayHello()
VBScript

msgbox(“Hello World”)
End Function
//–>
</script>
</head>
<body>
<script type=”text/vbscript”>
<!–
document.write(“Hello World”)
//–>
</script>
<input type=”button” onclick=”sayHello()” value=”Say Hello” />
</body>
</html>
It will produce the following result: Hello World message with a ‘Say Hello’ button. Upon Clicking on the button a message box with a message “Hello World” is displayed to the user.
VBScript in External File
As you begin to work more extensively with VBScript, you will likely find that there are cases, where you are reusing identical VBScript code on multiple pages of a site. You are not restricted to be maintaining identical code in multiple HTML files.
The script tag provides a mechanism to allow you to store VBScript in an external file and then include it into your HTML files. Here is an example to show how you can include an external VBScript file in your HTML code using script tag and its src attribute:
<html>
<head>
<script type=”text/vbscript” src=”filename.vbs” ></script>
</head>
<body>
…….
</body>
VBScript

</html>
To use VBScript from an external file source, you need to write your all VBScript source code in a simple text file with extension “.vbs” and then include that file as shown above. For example, you can keep the following content in filename.vbs file and then you can use sayHello function in your HTML file after including filename.vbs file.
Function sayHello()
Msgbox “Hello World”
End Function

In this post, we will outline the features of VBScript, which stands for Visual Basic Scripting and is a subset of Visual Basic for Applications (VBA), a Microsoft product integrated not only into Microsoft software like MS Project and MS Office but also into third-party tools like AUTO CAD.

**Features of VBScript:**

1. **Lightweight:** VBScript is a lightweight scripting language with a rapid interpreter.

2. **Case Insensitive:** VBScript is predominantly case insensitive, featuring a straightforward syntax that is easy to learn and implement.

3. **Object-Based:** Unlike languages like C++ or Java, VBScript is an object-based scripting language, not an Object-Oriented Programming language.

4. **COM Usage:** It utilizes the Component Object Model (COM) to access elements within the execution environment.

5. **Host Environment:** VBScript requires a host environment for successful execution, such as Internet Explorer (IE), Internet Information Services (IIS), and Windows Scripting Host (WSH).

**VBScript Version History and Uses:**

VBScript was introduced by Microsoft in 1996 with its first version, 1.0. The current stable version is 5.8, available with IE8 and Windows 7. VBScript has a wide range of applications, including:

1. **Automation Testing:** It is used in popular automation testing tools like Quick Test Professional (QTP).

2. **Windows Automation:** Windows System administrators use VBScript within Windows Scripting Host to automate Windows Desktop tasks.

3. **Web Development:** Active Server Pages (ASP), a server-side scripting environment for dynamic webpages, employs VBScript or JavaScript.

4. **Client-Side Scripting:** VBScript is used for client-side scripting in Microsoft Internet Explorer.

5. **Microsoft Outlook Forms:** VBScript is commonly used in Microsoft Outlook Forms, with application-level programming relying on VBA in Outlook 2000 onwards.

**Disadvantages:**

1. **Browser Compatibility:** VBScript is only supported by Internet Explorer, as other browsers like Chrome and Firefox do not support it. JavaScript is often preferred for broader compatibility.

2. **Limited Command Line Support:** VBScript has limited command line support.

3. **Debugging Challenges:** The absence of a default development environment makes debugging in VBScript more challenging.

**Current Status of VBScript:**

The current version of VBScript is 5.8. With the development of the .NET framework, Microsoft has chosen to support VBScript within ASP.NET for web development. As a result, there won’t be any new versions of the VBScript engine, but Microsoft’s Sustaining Engineering Team is addressing defect fixes and security issues. VBScript will continue to be shipped as part of all Microsoft Windows and IIS installations by default.
