MFC(VC6.0和VS2008)采用ADO访问access数据库（学生成绩管理系统）
在MFC下，采用ADO技术访问access数据库，做的一个很小的学生成绩管理系统。个人觉得对于初学数据库的人来说，是一个很不错的资源。编译时保证头文件stdafx.h中“#import "C:Program FilesCommon FilesSystemadomsado15.dll" no_namespace rename("EOF","adoEOF")”路径正确。本工程具有VC6.0和VS2008两个版本。

Verilog串口通信程序(详细注释)
Verilog串口通信程序，详细注释自己看了很多材料以后，精心整理的串口通信实验原理和指导，在网上找了很多代码，大部分因为没有很好的注释，看起来很头疼，于是自己写了一份，附带详细的注释，在modelsim仿真器上已经得到验证，现在传上来，仅供参考。PS1:最后部分给出了一个测试文件，写的非常简单，只是验证了功能，不是很好的测试；PS2：代码部分看上去有点乱，因为在word中代码的层次结构无法清晰显示，如有需要，下载后把代码copy到notepad++这种类似的专用变成工具里面，就很清晰的显示代码和注释了。
