打印的人最喜欢的，用C＃写的，可以把现有的多页pdf合成的工具...

FLUENT中的源项UDF，初学UDF可以下载下来学学。(this is a source UDF,IF you want it you can download .thank you! )

中心画圆 使用vc6.0实现 多多指教(draw a Circle use vc6.0)

刚做完的lcd12864 全中文多级菜单驱动程序．自认为通用性很好．在wave下编译通过．(Lcd12864 just finished the whole Chinese menu-driven multi-level procedures. Since the general good think. In the wave passed under the compiler.)

C#使用神经网络实现光学字符识别(OCR)源代码(Csharp use the neural network optical character recognition (OCR) the source code)

本文首先介绍了逆变电源的发展现状及趋势。文中分析了适合数字控制的基于DSP 处理器 TMS320F2812 和智能功率模块（IPM）的逆变器硬件；介绍了 SVPWM逆变技术的基本理论，详细推导出了五种具体的 SVPWM 实现模式，并通过比较说明不同实现模式的优缺点，得到本课题采用的一种优化模式，设计研究了基于 SVPWM控制方式的软件；介绍了 Q 格式的基本理论，在程序中变量间的运算采用 Q 格式，提高了系统数据运算的速度和精度，实现了在定点处理器上进行高性能的浮点运算；详细讨论了片上模数转换模块的转换误差来源及影响，研究了减小转换误差的方法，采用了软件方法来对转换结果进行实时校正，提高了模数转换的准确度。(In the first, the current situation and development trends of the inverters are presented in the paper. Following is the analyses of hardware of the inverter suiting for digital control based on digital signal processor TMS320F2812 and the intelligent power module(IPM) the basic theory of space vector pulse width modulation (SVPWM) is introduced, five specific SVPWM modes of implementation are educed detailedly, following by the comparison which shows the advantages and disadvantages of different patterns, an optimization mode is got which is used in this project, and the software is designed based on SVPWM control pattern the basic theory of Q format is presented, variable Q format is adopted during the procedure for the calculation which improves the operation of the system data speed and precision, achieving the targeted processor for high-performance floating-point operation in the fixed-point DSP the error sources and effects of the on-chip analog-to-digital conversion module(A)

一、源码描述 这是一款基于Socket的异步通信系统--SanNiuSignal.DLL已开源，主要实现了 客户端与服务器端之间的信息传递，可以发送图片、txt文件，对于学习C#网络编程的朋友们来说，比较具有学习价值，值得推荐一下，感兴趣的朋友欢迎下载 研究一下。二、功能介绍该源码主要实现了客户端与服务器端之间的通信功能。三、注意事项  1、开发环境为Visual Studio 2010，无数据库，使用.net 4.0开发。     2、该源码比较适合学习交流使用。

显示系统时间，按秒更新。用DateTime.Now实现。-Time display system, according to second update. Implementation using DateTime.Now.

这是一个关于UDP客户端的代码，是用WINSOCHET编写的(This is a study on UDP client code is written WINSOCHET)
