NTDLL.DLL): 0xC0000005: Access Violation問題：

 

 

A-------在內部進行調試的時候發現，是調用了new操作符的緣故。 

很不理解，在dll中調用new操作符會出現這麼一個問題，網路上搜尋，在微軟msdn論壇（具體地址：http://forums.msdn.microsoft.com/zh-CN/vclanguage/thread/951a04be-6b52-4617-b396-9c35e3755759/）上搜尋到相關問題。 

 

於是按照說明，將dll的產生方式修改為"共用mfc方式" 

         project properties -> general -> Project Defaults->Use of MFC

         To set the properties "Use MFC In A Shared DLL " 

另外，在網上也發現另外一篇，console方面的， 解決辦法:使用c   runtime   

library的動態連結版本(在你的console工程中設定忽略所有的預設連結庫,然後連結到msvcrt.lib就可以了)（具體地址：http://www.poptool.net/software/p606/A60674501.shtml） 

B------ 一般出現此問題都是因為指標未初始化等出現的訪問違規。但我出現這個錯誤的描述如下：

      描述：vc程式在視窗中添加edit空間（或其他控制項）及對應變數後（都是通過類嚮導添加的，沒有認為因素），編譯及串連都能正常通過，但運行時會出現0xC0000005:Access 

        Violation錯誤。經跟蹤調試發現，當程式運行到C******App::InitInstance() 中的m_pMainWnd = 

      &dlg;語句時，發生錯誤。

      解決：重新Rebuilt All（全部重建）來重新編譯即可。
