您好!照着你的改过了，问题还存在，能讲清楚一点么?

樓主能否提供一下ID3V2的資料呀？

能不能给个邮箱我，整个程序的资料传给你,万分感激!

我这里VC6编译就一个错，改了就通过了。还能运行，除了生成了几个sqlX文件，没有发现有你说有运行问题。

不管是啥错误，贴出来呀，让我这手机党怎么看呀

我也是用ＶＣ＋＋６.０编译的，编译的时候没错，运行的时候显示("0x00401138"指令参考的"0x00130000"记忆体。该记忆体不能为“written.”)，第一次运行的时候程序是可以通过的，但第二天就不行了，是不是内存溢出了?

就改了上面你说的那一个吗？

没有发现，或许是你自己把大部分代码都注释了的关系。
如果不知道倒底是哪里出了问题，你可以在一些语句上下断点，从上到下用二分法下断点，然后找到是执行到哪里出了这个内存不能为读的情况，分析出情况的原因，多半是写数据的时候越界照成的。
