runtime error怎么解决
我写了一个程序，用到了数据库、socket、线程，程序运行一段时间后（时间不定，有时一下午，有是两三天）会出现runtime error，点确定后退出，这个问题很严重。请问各位遇到过么？怎么解决？
我曾经看过用try 。。。except忽略的说明，不过我在数据库部分使用了try。。。catch，好像try之间不能嵌套，请各位指教。

这是一个事后调试的情况，可以使用windows的Dr.Watson日志文件，能比较快速找到问题所在Top

先用win2k的任务管理器看你的程序有没有资源泄漏
内存，句柄，GDI等资源

++C++

to flyelf：
windows的dr.watson日志文件是不是就是事件查看器中查看的文件？
还有Try except怎么用啊Top

这个问题要首先想到是不是内存泄漏Top

比较可能的情况是数据库释放不是太正常的缘故Top

1.檢查一個線程用完之後是否及時釋放
2。檢查數據庫是否會有問題出現而使客戶機不能連接而你的程序沒有認真的檢查這種情況的發生
3。動態變量（動態數組）你是否每次都在用完之後釋放掉了
4。檢查你程序中定義的那些不常使用的變量而當你寫程序時而忘記了對他的認真檢查而出錯的可能性，即不要漏掉了不常使用的變量的檢查
5。可能查看一下系統日志看是否有系統出現問題的可能性Top
