很好的多线程例子。这个例子实现了线程池和工作消费模式-JobQ.dsp This file (the project file) contains information at the project level and is used to build a single project or subproject. Other users can share the project (.dsp) file, but they should export the makefiles locally. JobQ.h This is the main header file for the application. It includes other project specific headers (including Resource.h) and declares the CJobQApp application class. JobQ.cpp This is the main application source file that contains the application class CJobQApp. JobQ.rc This is a listing of all of the Microsoft Windows resources that the program uses. It includes the icons, bitmaps, and cursors that are stored in the RES subdirectory. This file can be directly edited in Microsoft Visual C++. JobQ.clw This file contains information used by ClassWizard to edit existing classes or add new classes. ClassWizard also uses this file to stor

这是一个网上电子表，双击可执行程序CLOCKNEW.exe,便可看到一张笑脸和与系统时间同步的电子时钟，按任意键退出！-This is an online electronic watches, double-click the executable CLOCKNEW.exe, we will see a smile and time synchronization system with the electronic clock, according to withdraw from the arbitrary keys!

本文较为深入地研究了 NURBS 曲线及其性质、相关参数计算方法。提出NURBS 曲线的阿当姆斯微分方程插补算法，并利用前、后差分结合代替微分 的方法，对初始迭代式改进得到参数快速递推式。利用参数快速递推式，同时辅以预估—校正法，通过适当的插补预处理与合理的近似计算，综合考虑轮廓 误差控制和进给加速度控制，实现了动态变步长的自适应 NURBS 曲线插补方式。可使机床在满足误差要求的前提下，以最大化进给速度对零件进行插补加 工，实现了插补精度和插补速度的优化，提高了加工质量和效率。在 NURBS插补加减速控制方面，本文利用 NURBS 曲线的对称性进行实时插补减速点的 预测，提出了插补前抛物线--直线--抛物线 S 型加减速控制新方法。其具有位置精度高、速度过渡平滑等优点，并且改变了原有控制方法的以弦线代替弧 线、每插补一步都要进行繁琐的曲线弧长计算的情况，有利于提高插补精度和实时性。

使剪贴板是系统中个进程共享的一块重要区域。在不同的应用程序之间传送数据的时候，首要的选择就是利用剪贴板。不仅如此，在同一个程序的不同窗体之间拷贝数据的时候也常常使用剪贴板。剪贴板是视窗操作系统中不可缺少的一部分。本程序演示了如何访问剪贴板中的各种数据。用VC访问剪贴板源程序-so clipboard system is out of a process of sharing important region. In different applications transmission of data between the time, the first option is the use of the clipboard. Not only that, with a program to copy between different forms of data often use the clipboard. Windows clipboard is an indispensable part. This program demonstrated how to access the clipboard data.
