VC编写Excel表格，增加，修改，删除，同时进行数据库的操作(visual c++ read writeexcel sheet,add ,delete,update excel field,and insert data base)

最近几年，社会上地理信息系统和电子地图技术越来越受到大家的关注，很多单位和个人都投入了大量的人力和物力进行了相关的设计开发。在这些实际的开发问题中，我想就公交车换乘自动查询系统的核心算法的设计和分析做一个不成体统的研究，还希望同志们能帮我指正错误，帮助提高。(In recent years, the community of GIS and digital map technology is receiving increasing attention to the U.S., many units and individuals have invested considerable human and material resources to carry out the relevant design and development. In the development of these practical issues, I would like to change bus system automatically query the core of algorithm design and analysis不成体统to do a study, and also hope to help my comrades error correction to help improve.)

本代码主要实现SVPWM的算法，主要针对dsp28335。PWM波的频率为10KHz，死去时间2us。(This source code mainly realizes SVPWM and dsp28335 is used.The frequency of pwm is 10Khz and dead band time is 2us)

dsp上实现的音频经典混响算法,四个梳状滤波加两个全通滤波器实现(dsp audio to achieve the classic reverb algorithms, 4 comb filter plus two all-pass filter to achieve)

强大的C++邮件服务器系统...不可多得.(Strong C++ mail server system ... rare.)

驱动开发教程,很不错,适合初学者看看,所选类别和开发环境不对(driver devel)

前两天为公司改程序，其中有一部分是要打印出报表。原来的程序是调用VB写的一个程序。那个程序用VBA方式实现的，在一个空的WORD表格模板里填入数据，让WORD去打印，效果还可以，就是速度很慢。但是这次，上次写代码的人已经不在这里了，我并不想去学VBA，无奈之下找到了一个Rob.A Fraydl写的打印类示例，但是里面没有我要的功能，只是示范了怎么去打印。于是自己重新的封装了一下，基本算是合格了。(two days ago for the company to change procedures, which are in part to print out statements. The original procedure was called VB write a procedure. VBA procedure that was achieved in an empty template forms WORD Lane Enter data, Let Word to print, the results were, and that is very slow. However, this time, the last person to write the code has been going on here, I do not want to go to school VBA, In desperation to find a Rob.A Fraydl write Print category example, but there's no I want function, the model is how to print. His own re-packaging it, and basically considered a pass.)

ProE/Toolkit开发库基于同步模式DLL动态链接库形式的二次开发工程。根据官方文档中实例修改实现了根据MFC窗口输入参数自动画圆柱、圆台、棱柱等基本几何形状。即完成了草绘、拉伸、旋转等基本操作的代码实现以及其组合的实现。（备注：软件版本是ProE Wildfire 5.0，对应的开发环境是VS2008。工程所需外部链接库网上可以查到。）(ProE/Toolkit development libraries based on the synchronous mode dynamic link library DLL form of secondary development projects. Modify achieved under MFC window input parameters the base geometry animation cylinder, round table, prism, etc., according to official documents instances. That completed a sketch, drawing, code rotation and other basic operations to achieve and realize its portfolio. (Note: The software version is ProE Wildfire 5.0, the corresponding development environment is VS2008 external link libraries needed projects can be found online.))
