VBScript is a scripting language designed to automate web page activities through the use of scripts. It requires an execution host like a web browser to run. Common uses of VBScript include form validation, animation effects, and displaying messages. VBScript code can be executed in Internet Explorer, Windows Script Host, IIS, Outlook Express, and the Windows Script Console. Code is inserted into HTML pages using <SCRIPT> tags and can be placed in the head or body section.
