说明：  C#打印控件源码,针对打印控件的处理情况 ，能够实现相关的控件打印(C# Print Control Source, for the processing of print control, can achieve related control printing)

c#的写字版程序我自己写的.本文探讨了使用C#从底层开发一个带格式的文本编辑器的任务，深入探讨了其中的文档对象模型的设计，图形化用户界面的处理和用户操作的响应，说明了其中的某些技术问题和解决之道。 (version of the writing process I wrote it myself. This paper discusses the use of C# development from the ground up with a format of the text editor's mandate, in-depth study of the document object model design, graphical user interface processing and user response shows some of these technical problems and solution.)

说明：  程序包中包括Chebyshev低通滤波器、巴特沃斯模拟低通滤波器、Cholesky分解、DFT算法、FFT算法，可以直接移植到嵌入式系统或DSP中实现。(Package includes Chebyshev low-pass filter, Butterworth low-pass filter simulation, Cholesky decomposition, DFT algorithm, FFT algorithm, can be directly transplanted to the embedded system or DSP to achieve.)

说明：  ALU示例（对于单周期cpu的Modelsim SE-64 10.4进行仿真）(Alu example (simulation for Modelsim se-64 10.4 of single cycle CPU))

可视化组件查看器，通过此程序可查看Windows的视觉组件，另外还带一个树型的列表控件。(Visual Component Viewer .This program can view the Windows visual components, also with a treelistview control.)

说明：  C#实现QQ功能，类似于腾讯，可以登录聊天等等(C# achieve QQ function, similar to Tencent, you can log chat, etc.)

完整实现了单源最短路径的算法。 采用的是贪心算法思想。(integrity to achieve a single-source shortest path algorithm. The greedy algorithm.)

使用 PI Expert 设计的20V 5A LED驱动电源。(PI Expert design using 20V 5A LED driver power supply.)

通过MediaPlayer控件对象播放Mp3文件。使用SetWindowRgn函数，使窗体呈现不规则形状。(Mp3 player through the MediaPlayer control object file. Use SetWindowRgn function, so that form irregular shapes.)

说明：  动态数组的实现， mutablearray 与array 的区别， 以及跳出循环的过程(The implementation of dynamic arrays, the difference between mutable arrays and arrays, and the process of jumping out of the loop)
