我们经常会遇到这样问题，怎样在非web程序或asp程序中使用mysql数据库呢？对于这个问题有两个解决方案:
1.使用mysql提供的api函数库。
很多有名的mysql客户端工具就是这样实现的，大名鼎鼎的winmysql工具就是这样的。这在大部分的开发工具中都可以实现。
比如vc,bcb,delphi,vb等，只要能调用第三方的api就能实现。但对程序员的要求很高，而且要熟悉一套mysql的api函数集，这不是对每个人都
很轻松的事。而且这种方法不能用于asp等程序，因为它不支持com对象。
2。第二种是使用myodbc驱动程序。
你可以到下载myodbc驱动程序，然后照着下面的做就可以了
第一种选择是下载完全安装包，这种包很大，但对于我们来说有用的只有myodbc.dll这个文件，却要下载这么大的文件，不太合适。当然，如果你
很菜的话，我建议你选择这种方式，这样容易些，但不符合cfans的作风，是吧。
第二种是直接下载myodbc.dll文件，只有几百k,但不太容易使用，本人经过很久摸索才找到使用它的方法。
首先你将包解开，将myodbc.dll 文件放到windowssystem 或 winntsystem32目录下，这取决于你的系统是win9x还是winnt(win2k)，你应该
知道吧。
然后打开一纯文本编辑器，如editplus,notpad之类，(取决于你的喜好)将下面一段话保存为一文件，扩展名为.reg,知道了吧，这是注册表文件，不要搞
错呀(不包括下面的一长串等号)
如果你用的是win2k请将第一行换成Windows Registry Editor Version 5.00
Windows Registry Editor Version 4.00 [HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INImyodbc driver] "UsageCount"=dword:00000002 "Driver"="C:WINNTSystem32myodbc.dll" "Setup"="C:WINNTSystem32myodbc.dll" "SQLLevel"="1" "FileUsage"="0" "DriverODBCVer"="02.50" "ConnectFunctions"="YYY" "APILevel"="1" "CpTimeout"="120" [HKEY_LOCAL_MACHINESOFTWAREODBCODBCINST.INIODBC Drivers] "myodbc driver"="installed"
至于为什么要写这些，你就不要问我了,我也不想回答，这是收费门先生说了算的(bill.gates)就这样吧.保存后，双击刚才的文件，应该叫xxx.reg 吧，然后选择确定，ok，搞定了。然后你打开odbc设置程序，，建一新数据源，选择myodbc驱动程序,剩下的就看你自己了。
