Design and implementation of a statistical chart imitating TeeChart control Q IAO Ping2an (Department of Computer Science, Xi an University of Post and Telecommunications, Xi an ,China) Abstract : This design is a statistic chart control using ActiveX technology to simulate Teechart control, and the development tod is C + +. Its main functionality is to read out data from the Database that is specialized. And t hen after a series of processing and computing, finally came out in a chart way. There are seven kinds of legend type in total. And two of them have both static and animate statuses. Key words :ActiveX control ; statistic chart ; Visual C + + (41 ) The research and application of mobile NFC communication terminals L U Kai,M EN G Xu2dong (College of Communications and Information Engineering, Nanjing University of Posts and Telecommunications ; Nanjing , China) Abstract : Wit h t he development of computer network and telecommunications, people need N FC technology more than ever. This paper first introduces basic characteristics of NFC technologies, presents the NFC technol2 ogy architecture. With the basis, it does further research on mobile NFC Communication Terminals and the function modules. Then the concrete applications of NFC technologies are shown. At last, the paper gives a prospective overview on t he application of mobile N FC Communication Terminals. Key words :NFC ;mobile communication terminal ; contactless ; peer - to - peer
