[醉疏雨]

程序关闭退出时，程序异常退出，，程序打出日志，搞不清是什么愿意引起的， 请诸位大神帮忙看看

强制关闭进程，这样不要吧，主要是要弄明白问题产生的原因

[赵4老师]

关闭时调用

WinExec("cmd /c taskkill /F /IM 你的程序名.exe",SW_HIDE);

理由请参考：http://bbs.csdn.net/topics/390787357

你非要钻牛角尖弄明白问题产生的原因： 崩溃的时候在弹出的对话框按相应按钮进入调试，按Alt+7键查看Call Stack即“调用堆栈”里面从上到下列出的对应从里层到外层的函数调用历史。双击某一行可将光标定位到此次调用的源代码或汇编指令处，看不懂时双击下一行，直到能看懂为止。 有时不将“调用函数名字＋各参数值，进入函数后各参数值，中间变量值，退出函数前准备返回的值，返回函数到调用处后函数名字＋各参数值＋返回值”这些信息写日志到文件中是无论如何也发现不了问题在哪里的，包括捕获各种异常、写日志到屏幕、单步或设断点或生成core或dmp文件、……这些方法都不行！ 写日志到文件参考下面：

感谢您的指点， 我已经找到了原因啦， 就是因为内存泄露， 我有一个单例类管理各个dialog,程序退出时没有对各个dialog进行清除
