- 代码不错，要是能有一个完整的程序出来就更好了
- 很好，调试成功。。有谁要是调试有问题的，可以联系我哈。
- 有用的资源，下载下来收藏！
- 只有代码，其他的都没
- 只有代码，乱的要死，不过还是谢谢了
- 还行吧，不过都放在全部代码同一个文件不好
- 代码不错，要是能有一个完整的程序出来就更好了
- 界面做的不错,源码也可以,
- 不错，但是没有相应的SQL
- 不知道怎么回事，我下载的代码运行时有错误，不能运行，看不懂，所以不知道错误是什么。
- 总的来说，代码写的不错，但是木有相应的数据库，连登陆输入什么都不知道
- 不错，可以用
- 没响应的sql，没仔细看
- 源碼和Sql都很詳細，謝謝樓主分享。
