ArcGIS Engine二次开发编程实例，里面有许多有用的例子！-ArcGIS Engine secondary development of programming examples, there are many useful examples!

包括部分空间算法，如计算两坐标点距离、判断两坐标点是否相等、计算叉积、计算点积、判断点p是否在线段l上、计算点bp以点op为圆心逆时针旋转dAlpha(单位：弧度)后所在的坐标点位置、计算指定半径圆上指定角度的弦长、计算由起点坐标和终点坐标构成的线段在指定距离和指定方向的垂点坐标等空间算法-Including some space algorithms, such as calculating the distance between the two coordinates to determine whether the same two coordinates to calculate cross product, point multiplication calculation to determine whether point p on line l above the calculation point to point op for bp counterclockwise rotation center dAlpha (units : radian) after the location where the coordinates of points, calculated on the specified radius of a round angle specified chord length, calculated from the starting point coordinates and end coordinates of the line constitutes a specified distance and specified direction of the vertical space coordinate algorithm

首先得安装MapX控件，并在VC源文件中引用CMapX的头文件，能够实现放大，缩小，添加图层数据，进行图层的管理-first be installed MapX, and the VC source quoted CMapX the first document to achieve zoom in and out, add layers of data, the management layer
