mfc 获取局域网Ip上次有内存溢出，我来说说解决办法！

方法：_CrtSetBreakAlloc(563); // 最好在你内存分配的前面加上内存溢出的行号；

快捷键:shift+F11 进行调试找到你内存溢出的位置进行修改即可！

下面就以我代码例子如下：（我的主要问题在于，使用了cstring 转 char 的转换函数，内存分配了，并未进行 delete []）

_CrtSetBreakAlloc(556);
	m_devIpShow.DeleteAllItems();
	hThread = (HANDLE)_beginthreadex(NULL, 0, &SecondThreadFunc, NULL, 0, NULL);
	WaitForSingleObject( hThread, INFINITE );  
	CloseHandle(hThread);</span>
