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