Windows NetMeeting 3

Windows NetMeeting 3


Microsoft Windows NetMeeting 3 allows real-time collaboration through standards-based client support of data, audio, and video Internet conferencing. NetMeeting provides a software application programming interface (API) that lets programmers and Web-page designers include collaboration and conferencing for applications that are NetMeeting clients. Data conferencing includes application-sharing, chat, whiteboard, and file transfer features. Other features include remote-desktop sharing and gatekeeper support.

Where Applicable

NetMeeting permits creation of Web-based and traditional applications that provide enhanced communication and collaboration capabilities. Such applications range from e-commerce Web sites providing video and audio communication with customer service representatives, to help-desk applications, to collaboration on documents in real time across a network.

Developer Audience

NetMeeting 3 provides components for a wide range of developers. The NetMeeting 3 API provides a scripting guide for Web developers and other scripting application developers, a low-level T.120 application guide, and a COM guide. Because most of the components are implemented using the Component Object Model (COM), they can be called from any COM-supporting languages, such as C/C++, Microsoft Visual Basic®, and Java.

To take full advantage of NetMeeting, you should be familiar with the following technologies: H.323 and T.120 conferencing standards, Microsoft ActiveX® technologies, HTML, the Windows Sockets API, and COM.

Run-Time Requirements

The NetMeeting 3 client components require one of the following hardware configurations:

  • Windows 95 or Windows 98

  • 90 megahertz (MHz) Pentium processor

  • 16 megabytes (MB) of RAM

  • Microsoft Internet Explorer 4.01 or later
