Getting Started
To develop single-user and multiuser applications by using the MSN® Messenger Activity object model, you should be familiar with:
- The MSN Messenger client.
- How to manipulate dynamic HTML (DHTML) using a scripting language such as Microsoft® JScript®.
- An event-driven programming language such as Microsoft Visual Basic®.
The Activity object model can be manipulated by using a scripting language such as Microsoft Visual Basic Scripting Edition (VBScript), JScript, or JavaScript, and the output is displayed in a DHTML window. The object model makes it simpler to write compelling applications by providing a multiuser framework. Because the Activity programming environment is part of the MSN Messenger client, you can take advantage of existing contact lists and other MSN Messenger features.
You can start with a new or existing HTML page. Your HTML page will be displayed within the MSN Messenger client. The largest window that the MSN Messenger client can display is 500 � 500 pixels, so you should design your Launch Site application accordingly. Event handlers and functions are placed in the scripting part of the document, as shown in the following example. Output and information are displayed in the body part of the document. If you have an existing application or game that uses DHTML, you may be able to make it into a MSN Messenger Activity by adding some additional scripting.
<HTML> <HEAD> <!-- Script area --> </HEAD> <BODY> <!-- Display area --> </BODY> </HTML>
