AGPS定位基本原理浅析，AGPS（Assisted GPS，A-GPS，网络辅助GPS）定位技术结合了GPS定位和蜂窝基站定位的优势，借助蜂窝网络的数据传输功能，可以达到很高的定位精度和很快的定位速度，在移动设备尤其是手机中被越来越广泛的使用。(AGPS positioning the basic principles of analysis, AGPS (Assisted GPS, A-GPS, network-assisted GPS) positioning technology combines GPS positioning and cellular base station location advantage, with data transmission function of the cellular network, can achieve high positioning accuracy and very fast positioning speed, especially in the mobile phone devices are more widely used.)

说明：  利用Select into生成临时表，使用SQL语句生成数据库中的临时表(Use Select into to generate temporary tables, use SQL statements to generate temporary tables in the database)

这编码帮着展示图像代表情况，每年学生报告附带图片(This code helps you to show graphical representation for situations like generating annual report for student with its graph. This code creates Pie Chart likewise we can also create Bar Chart. )

说明：  成绩管理系统，用于管理培训机构，学校等成员成绩。(Achievement management system, used to manage the performance of training institutions, schools and other members.)

this source is how to get disk list. you will know how to use GetVolumeInformation function.

此种模型绘制类似米字形的网格。由于整个过程递归调用绘图函数，所以可以根据误差判断绘制DEM的精细程度，从而绘制出不同精细程度的DEM，为解决漫游中数据量较大而引起的画面不流畅现象提供了模型基础。 本文并没有对LOD作研究，只是给出了四叉树的建立和遍历绘图的方法。 #include "Pt3d.h" //空间点类(主要记录空间点的x,y,z) (Rendering such a model similar to rice-shaped grid. Recursive calls as a result of the whole process of mapping function, so it can be judged according to the error map of the fine DEM, thus rendering a different degree of precision DEM, for the settlement of roaming in the amount of data arising from the larger screen does not provide a model of fluid based on the phenomenon. This article does not LOD for research, but given quadtree traversal of the establishment and mapping method.# Include Pt3d.h // space-point type (mainly recorded space points x, y, z))
