这是一款使用MFC编写的基于C++语言的科学计算器程序，功能齐全。(MFC C++ calculator)

This component implements seven COM objects

输入三点的三维坐标，求立体空间的圆心所在，使用了对话框架构，里面的算法函数可以提出来单独使用(importation of 3D coordinates for a three-dimensional space where the center of a circle, use the dialog box structure, function inside the algorithm can be made to use separate)

MDI 应用程序是另一类重要的文档视结构程序。它的特点是：用户一次可以打开多个文档，每个文档对应不同的窗口；主窗口的菜单会自动随着当前活动的子窗口的变化而变化；可以对子窗口进行层叠、平铺等各种操作；子窗口可以在MDI 主窗口区域内定位、改变大小、最大化和最小化，当最大化子窗口时，它将占满MDI 主窗口的全部客户区。MDI 不仅可以在同一时间内同时打开多个文档，还可以为同一文档打开多个视图。在Windows 菜单下选择New ，就为当前活动文档打开一个新的子窗口。 (MDI application is another important document, as the structure of the procedure. It is characterized by: a user can open multiple documents, each document corresponds to a different window main window menu automatically with the current activities of the sub-window changes can be stacked pair window, tile, etc. types of operation MDI child window in the main window positioning the region to change the size, to maximize and minimize, maximize the child window when it will occupy the entire main window MDI client area. MDI at the same time not only to open multiple documents at the same time, can also open multiple views of the same document. In the Windows menu select New, on the activities for the current document open a new sub-window.)

实现仿VC界面的程序，能实现文件目录的读读取，日历控件的添加选择，对CTreeCtrl类进行了重新封装(Realization of imitation VC interface procedures, can achieve read read file directory, select the calendar control to add the CTreeCtrl class has been re-packaged)

水晶报表实例,这是在里做水晶号表,很好用的,用C#写的,(Crystal reports as an example, this is the table, doing the crystal is very useful, written in c #,)

又是一个风格化窗体的源码,厌倦了WINDOWS的窗体(Is also a stylized form source code, tired of WINDOWS forms)

在一view窗口内使用grid控件(Using grid control in a view window)

VC自绘的漂亮窗体界面实例，DrawForm源码，用VC自绘了一个漂亮的登录窗口界面，不知道有没有人感兴趣，我觉得这个技术学会了对于美化些窗口界面还是有帮助的。自绘技术也是值得研究的。(VC self-painted beautiful form interface instance, DrawForm, source, painted with VC and a nice login window interface, do not know no one was interested, I think this technology is learned to help beautify window interface. Self-drawn, is worthy of study.)

发送ARP包,可以遍历局域网里的主机,也可以得到主机名(Send ARP packets, you can traverse the host in the local area network, or you can get the name of the host)
