NetMeeting Conference System
Abstract: NetMeeting Conference system is a modern application software to enable users to build a meeting without gathering together in a small meeting room by the help of Internet. The main programming software of the NetMeeting Conference system is Visual C++6.0, which is based on API port in the RTC technology, In order to make sure the system programmed well, the VMware virtual machine gives its great effort.
Nowadays with the modern technology, my project show its great convenience vary users from little LAN, small company, even in a big enterprise. Due to the Internet, they can do the NetMeeting, Video Conference, chatting online, etc. Users can use different kind of tools in my project to share their screen to the others or chatting in a chatting room as well. NetMeeting Conference systems is not only a good application for user, but also be approved by its convenience, efficiency and timeliness.
In order to meet the standard level of my project, I use the VMware virtual machine to do my graduation project, when I do the program debug, two of the virtual machine set on my laptop, give me great help. Thanks to virtual machines, I can know where of my project need be modified or be improved.
