现有基于M apX 的最优路径分析, 对于TAB 格式数据拓扑信息的提取方法单一, 且未考虑导航特征。该文 结合道路导航特点, 提出了一套基于MapX 的最优路径分析解决方案。首先由T AB 格式数据提取拓扑信息, 为最 优路径分析奠定数据基础 然后针对导航的特征, 即最优路径分析的起点和终点可能出现在道路网外, 着重讨论了 对于Dijkstra 算法的拓展。(M apX the optimal path analysis, a single topology information for the TAB format data extraction methods, and did not consider the navigation features of. In this paper, combined with road navigation features, a set of optimal path analysis based on MapX solution. First extract topology information by T AB format data, to lay a data base analysis for the optimal path and navigation features, the start and end points of the optimal path analysis may appear in the road network, focused on the expansion of the Dijkstra algorithm.)

说明：  用VB实现的坐标转换，功能简单了点，但很实用，WGS-84,B-54之间的相互转换。(VB coordinate conversion, a simple functional, but very useful, WGS-84, B-54 between the conversion.)

串口通信，对串口发出的数据进行读取和处理，进行检测(Serial communication, read and process the data sent by the serial port, and detect it.)

说明：  调试使用的串口助手，程序源码，功能齐全，可以调试程序(Serial Port Assistant for Debugging, Program Source Code, Full-featured, Debugging Program)

说明：  vb+mapobjects进行二次开发，实现地图放大缩小，鹰眼等功能(VB + MapObjects for secondary development, map zooming and zooming, EAGLE-EYE and other functions)

计算机网络实验做得串口，非原创，只是为了下载方便。(Computer network experiments do serial port, not original, just for download convenience.)

这个例子主要是vb.net对excel表格进行读操作和写操作,读操作的代码有点问题，请将代码 xlBook.Close() xlApp = Nothing 交还控制给Excel xlBook = Nothing xlSheet = Nothing 更改为 xlBook.Close() xlBook = Nothing xlApp.Quit() xlApp = Nothing xlSheet = Nothing(This example mainly describes vb.net operates excel spreadsheet for reading and writing，writing codes have some errors please change xlBook.Close() xlApp = Nothing xlBook = Nothing xlSheet = Nothing into xlBook.Close() xlBook = Nothing xlApp.Quit() xlApp = Nothing xlSheet = Nothing)

VB学习代码库，学习VB的绝佳参考，更加得心应手(VB code base learning, learning VB excellent reference, more handy)

画陡坎，里面有详细的程序语言，使用时只要打开mapinfo加载即可(Painting scarp, which has details of the programming language, when used as long as open mapinfo load can)
