VBScript and Java Applets
You can integrate the applets into your programs and directly use their capabilities from your script. It's very much like the ActiveX object integration model. There are some differences, such as the events that ActiveX provides, but there are also a lot of similarities.

Timer Control
The Timer control belongs to the type of control that is not visually oriented. The timer control is not intended to be something the user sees; it is a building block for your scripts.

Animated Button and Preloader controls
Microsoft has made available a number of controls that you can use in your own VBScript HTML pages. Keep in mind that in order for these controls to work, it's up to the client (your reader) to install them on his or her machine. These controls are freely distributable and can be made available to people interested in seeing and using your implementation of the object on their machines.

Attributes for ActiveX objects
Some of the attributes for ActiveX objects aren't new to HTML. For instance, the ALIGN, BORDER,HEIGHT, HSPACE, VSPACE, and WIDTH attributes are used with the <IMG> tag. However, because the <OBJECT> tag is part of an advanced specification, it supports the advanced alignments and spacing techniques.

Inserting ActiveX Controls in the Web Page
Each ActiveX control has a set of properties and methods that can be set and reacted to. They are programmed just like any other object on the Web page. You set the properties of the control, and then your script reacts to messages sent by the user interacting with the objects in the browser.

Custom Controls in VBScript. Brief of ActiveX controls
An ActiveX control is different from a VBX or DLL because the control is registered with the operating system when it is installed. After an ActiveX control is registered, it can be used as a component by any application developed, using any one of many different development environments, including VBScript.

CGI and VBScript
Common Gateway Interface (CGI) is one of several ways you can use to add interactivity to your Web pages. CGI represents a simple protocol of communication between the Web forms and the programs that reside on the Web server. This is a quite different technology then VBScript which is included in the HTML
file implemented on the client side

Link Object
The basic property of the link object is the length property, which returns the number of the links in the document. Each link is a member of the links array. Because the hyperlinks in a document are destinations, the link object's properties are identical to the properties of the location object; however, they are read-only.

Location Object
The Location object contains information about the current documents location and can be used to manipulate browser navigation. The Location object has no events.

its frames. You have already used the document object applying the document.write method to write strings on the current document. This method enables you to create
documents on the fly. You use this object most often in programming your Web pages, and this section discusses its properties and methods in detail.

Ways to Attach Code to Events
