Acis R15，hoops/mfc 12.0， xt12.0 写的一个 图形绘制软件的框架。Vc 2003 平台。 有基本的基于上面所述的组件组成的3D造型的演示。(Acis R15, hoops/mfc 12.0, xt12.0 to write a graphics rendering software framework. Vc 2003 platform. Based on the above basic components described in the presentation of 3D modeling.)

行程编码的基本原理是：用一个符号值或串长代替具有相同值的连续符号（连续符号构成了一段连续的“行程”。行程编码因此而得名），使符号长度少于原始数据的长度。只在各行或者各列数据的代码发生变化时，一次记录该代码及相同代码重复的个数，从而实现数据的压缩。(The basic principle of run length coding is: a symbolic value or string length instead of having the same value of consecutive symbols that symbol length less than the length of the original data (consecutive symbols constitute a period of continuous stroke run-length encoding, hence the name.) . Only when the code for each row or each column of data is changed, the recording time code and the same number of code duplication, in order to achieve compressed data.)

使用编写程序，实现一个坐标轴功能，进行数据分析与运算(Use programming to implement a function of coordinate axes, data analysis and calculation)

程序功能： 1.快速启动应用程序，主要是使用热键。还可以让程序定时启动。 2.锁定计算机。在98下面完全奏效，在2000xp下面不能完全有效。支持定时锁定、启动锁定。 3.定时提醒。 4.关机 5.关闭由本程序启动的子进程，并可以查看他们的进程信息。 6.保护本程序不被非法关闭。 FastRun.exe：主应用文件 Frpo.exe：后台保护程序 msgdll.dll：导出一个自己画的messagebox的动态连接库(procedures functions : 1. Quick Start applications, primarily using hotkey. It can also allow the procedure regularly launched. 2. Lock computer. 98 Below in Congress, in 2000 xp below not completely effective. Support regular lock, lock activated. 3. Timing reminded. 4. Off 5. Close by the commencement of the children, and can view their information process. 6. Protection of the procedures are not being closed.

VC++利用Hook钩子实现的阴影菜单，不要误认为是Winodws系统自带的阴影菜单，仔细看你就会发现两者是不一样的，一样令人羡慕不已，尤其是使用钩子实现，相信对VC++编程者来说，有空的时候还是要看一下哦！虽然大家对这种效果已经司空见惯了，但实现起来没有想像的那么简单，因此具有参考价值。(VC++ to use the realization of the shadow of hook Hook menu, do not mistakenly think it is the shadow of Winodws own menu system, look carefully and you will find they are not the same, as is envy, especially the use of hooks to achieve, I believe VC++ programmers, the time or the time to look at Oh! Although there have been commonplace this effect, but not as to achieve the so simple, it has a reference value.)
