Microsoft Visual Basic Scripting (VBScript) Language brings active scripting to a wide variety of environments, including Web client scripting in Microsoft Internet Explorer and Web server scripting in Microsoft Internet Information Service (IIS).
Environments Where VBScript Can Run
VBScript is a client-side scripting language. It is a light version of Microsoft Visual Basic. The syntax of VBScript is very similar to that of Visual Basic.
VBScript cannot run its code on its own. It needs a bigger programming language to host it. Right now, there are 3 environments where VBScript can run.
- IIS (Internet Information Server) – Microsoft’s web server
- WSH (Windows Script Host) – The native hosting environment of the Windows OS
- IE (Internet Explorer) – The simplest hosting environment we can use to run VBScripts
Disadvantages of VBScript
- The main disadvantage of VBScript is that most browsers except Internet Explorer will not process VBScript code.
- VBScript will not run on computers that run on operating systems other than Microsoft Windows including Linux, Mac etc.
Where Should I write the Program?
We should write VBScript code in Notepad. Now, VBScript is used as the default scripting language of ASP. Example:
i = 10
VBScript is not Case Sensitive.
