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.)

使用vb实现ping命令，可ping指定IP并返回结果(Vb realize the use of ping command, can ping the specified IP and return results)

logistic、malthus人模型都可以用于预测呈指数增长的数据模型，预测未来的人口的等数据，是由人口学家提出的，可用于预测未知的数目，以及检测一些模型所得结果的正确性。(logistic, malthus human model can be used to predict an exponential growth in data model, to predict the future, such as population data, is proposed by the demographer can be used to predict the number of unknown, as well as a number of model testing the correctness of the results.)
