体积小巧曲线控件没，实现一般曲线的各种画法，虽然很简单但很好用。(compact design Curve Controls did not achieve normal curve of the painting, although very simple but very good use.)

简单的图形学SRGP教学包运用实现。 A．实现一个下拉菜单软件包，其高层设计见2.2.6节、2.3.1节、2.3.3节中的代码段。软件包通过从输入文件读入字符串来初始化菜单条和菜单体。程序可以通过关闭菜单条使标题消失，也可以激活一个菜单（以各菜单标题在菜单条上的水平位置作为参数）来使菜单出现。 (Simple graphics SRGP realize the use of teaching packages. A. The realization of a drop-down menu package, and its high-level design, see section 2.2.6, section 2.3.1, section 2.3.3 of the code segment. Package from the input file is read into the string to initialize the menu and menu body. Procedures can be closed so that the title menu disappear, but also can activate a menu (in the menu heading in the menu bar on the horizontal position as a parameter) to make the menu appear.)

用四阶龙格-库塔法求系统在U单位阶跃输入下该系统的响应曲线(Using the four order Runge Kutta method to find the response curve )

本代码实现了一个地图比例尺的功能，方便各种地图类型代码的基本控件使用(This code implements a function of map scale to facilitate a variety of map types of code to use the basic controls)

这个程序是用Breseham画法在visual c++平台下画直线和圆。可以对图像进行刷新，画多条直线，多个圆(This procedure is used Breseham paint in visual c++ platform for the next drawing a straight line and circle. Can refresh the image, painted more than a straight line, a number of round)

中点画圆与中点画直线 二维图形变换 多边形填充 计算机图形学实验(The midpoint Circle draws line in two-dimensional graphics transform polygon fill, computer graphics experiments)

教你如何使用画刷，MFC里面的画刷，文件里面是相关的代码。(tell you how to use the brush of MFC,there s the relative code inside the file.)

Teechart绘图应用实例（随机线条、动态画线、画圆）(Teechart drawing application examples (random lines, dynamic draw lines, circle))

单文档绘图工具，包括直线，曲线，扇形，圆形，圆角矩形，矩形等图形，还可以设置线条的颜色等属性。(Single document drawing tools including lines, curves, fan-shaped, round, rounded rectangle, rectangle and other graphics, you can also set the line color and other attributes.)

读取DXF文件(2000,2002版本),包括了分层管理数据的思想,供大家参考(read DXF files (version 2000, 2002), including a hierarchical data management thinking, for your reference)
