Visual Leak Detector(vld) 内存泄露检测

[hili210]

一些本地文件的泄露可以检测并能知道在哪一行出错，但是有些泄露是系统库文件，貌似很难到问题所在
因为是数据库服务器端，所以内存泄露得要解决掉，工程是MFC对话框模式（直接建一个对话框工程加入vld检测没有任何泄露）

这个是内存泄露的部分信息：

还有一些，就不贴出来了，如果需要什么代码的话我会尽快贴出来，我已经看过所有内存泄露，没有提示本地文件哪一行出现问题，貌似就剩下了这些库文件了，好像是堆栈的内存泄露，求高手，谢谢了

这个不要考虑。

[赵4老师]

检查是否资源泄漏的办法之一： 在任务管理器 进程 查看 选择列 里面选择：内存使用、虚拟内存大小、句柄数、线程数、USER对象、GDI对象 让你的程序(进程)不退出,循环执行主流程很多遍，越多越好，比如1000000次甚至无限循环，记录以上各数值，再隔至少一小时，越长越好，比如一个月，再记录以上各数值。如果以上两组数值的差较大或随时间流逝不断增加，则铁定有对应资源的资源泄漏！

嗯……也是，虽说有点不放心，不过也没办法，我今天晚上回去再看看
