introduction to software engineering

在VC环境中利用MAPX实现在地图中的直线测量与折线测量。-in VC Connection use the map to achieve the linear measurement and measurement dogleg.

几个实现经纬度与投影坐标计算的函数.可以供程序员参考-achieve several projection coordinates of longitude and latitude and calculation functions. Can reference for programmers

生成tin（不规则三角格网）的算法，根据区域的有限个点集将区域划分为相等的三角面网络-Generation tin (irregular triangular grid) algorithm, according to the region will be a finite number of points equal to the region is divided into triangular surface network

这是个GIS程序，能够实现比例尺放大、缩小、全屏显示，以及在状态栏显示时间和鼠标位置，以及自建一个CDIALOGBAR，来实现画笔的线形和粗细。-This is a GIS procedures, the scale can be achieved to zoom, full-screen display, and the status bar shows the time and location of the mouse, and a self CDIALOGBAR to achieve the linear brush and thickness.

一个计算面的平均高程的程序，可以求得任意形状的面的平均高程。-A calculation of the average surface elevation of the procedure, you can find any shape of the average surface elevation.

This program demonstrates the usage of the select() routine.

本程序是德国冯哈伯公司开发的电机实例程序，非常适合于对电机二次开发的人员下载实用，此电机的在市场上价格不低-This program is developed by the German Faulhaber motor examples of procedures, very suitable for the secondary development of the motor to download the utility, this motor on the market price is not low

应用背景程序使用C#+ Arcgis Engine进行界面开发，实现基本的shape格式数据读取显示，图层拖动排序，还有空间分析功能。关键技术shape格式数据读取显示、空间分析功能以及图层拖动排序。

shp演示程序 主要改正了使用点线符号（PointLineSymbol）绘制时的死机问题，并调整了几处不正确的bitmap用法。此外增加了小工具shp2esd，用来批量转换shapefile为esd文件。 把这几个目录覆盖掉1.0版的同名目录（先下载easymap1.0），重新编译就可以使用了。 -shp demo program to correct the use of the main points and lines symbols (PointLineSymbol) drawn at the time of death, and adjust the number of incorrect usage bitmap. In addition an increase of small tools shp2esd, used for bulk document conversion shapefile for esd. Several out this directory cover version 1.0 of the same name directory (first download easymap1.0), the compiler can re-use.

VB+ArcEngine写的二次开发，部分集锦代码-VB+ ArcEngine write the secondary development of part of Collection code
