Ques : What is VB script ?

VBScript is a member of Microsoft's Visual Basic family of development products. Other members include Visual Basic (Professional and Standard Editions) and Visual Basic for Applications, which is the scripting language for Microsoft Excel. VBScript is a scripting language for HTML pages on the World Wide Web and corporate intranets. VBScript is powerful and has almost all the features of Visual Basic. One of the things you should be concerned about is the safety and security of client machines that access your Web site. Microsoft took this consideration into account when creating VBScript. Potentially dangerous operations that can be done in Visual Basic have been removed from VBScript, including the capability to access dynamic link libraries directly and to access the file system on the client machine.
