DDA直线绘制程序实现，可以是任意的直线。(DDA line drawing program, a straight line can be arbitrary.)

当用户按下鼠标左键在如下图所示的面板上移动鼠标时，根据鼠标的移动轨迹在面板上画图。(When the user presses the left mouse button on the panel as shown in the following figure to move the mouse, according to the mouse movement trajectory in the panel drawing.)

CAD下VBA二次开发，用来展高程点，txt文件，已经把离散点网格化了(CAD lower VBA secondary development, to show elevation point, txt file, has the discrete points of the grid)

说明：  graphic game developing source code

绘图程序，可以自由绘制直线、矩形、圆、多边形，可以设置颜色和宽度，并且能够进行图元基本操作，如剪裁、缩放及填充功能。(Drawing program, free to draw lines, rectangles, circles, polygons, you can set the color and width, and can be primitive basic operations, such as cropping, scaling and filling functions.)

MFC画图程序,实现动态画直线、椭圆等功能(MFC drawing procedures, to achieve dynamic painting a straight line, oval and other functions)

解析法面积计算,读数据文件,计算后生成结果文件,任意多边形的顶点坐标,然后 计算出面积是平方米和公顷(analytical calculation, reading data files, calculation results generated documents, arbitrary polygon vertices, then compute the area of square meters and ha)

可以画图的功能强大cad软件一定不要错过你值得拥有制图高级工具(You can paint the powerful CAD software must not miss you worthy of drawing advanced tools )

MFC 画出简单的坐标 并通过按钮产生随机点坐标（横坐标逐渐增大纵坐标随机）存入文件中 另一按钮实现读出数据并将点连成折线(MFC drawing simple coordinate and through the button generates random point coordinates (abscissa increases ordinate random) into a file and another button to achieve read data points connected into line)

画画的,一个简简单单的画画的小型的C++编的软件(Paint of, a Chien is simple painting of list of small scaled C++weave of software)
