之前碰到論壇里有幾個好友，說程序不時的崩潰，什么xxoo不能read的！ 如果光要是這個內存地址，估計你會瘋掉~~
所以分享一下基本的調試技巧，需要準備的工具有WinDbg + VC6.0，
下面是自己整理的一份自動生成DUMP文件的源代碼，只需要添加到工程即可，源代碼如下：

具體參考方法如下：
1、在CXXDlg::OnInitDialog()中添加這樣一段：
?

?
測試代碼如下：

我們在雙擊確定按鈕時的響應代碼如下：
?
?
[cpp] view plaincopyprint? void?CTestDlg::OnOK()???{????????????Fun1(NULL);??}??void CTestDlg::OnOK() { // TODO: Add extra validation here Fun1(NULL); }
2、設置VC編譯選項，勾選生成MAP和Debug Info:
3、將編譯生成的Release目錄中的pdb、map文件保存起來，以后調試會用到：
4、運行程序，單擊確定按鈕出現異常后自動重啟，并創建一個Log文件夾，里面生成dump文件:
5、我們打開WinDbg，設置一下pdb路徑(File \ Symbol File Path)：
6、用WiinDbg打開dump文件（File \ Open Crash Dump）
7、輸入命令!analyze -v，等待幾秒后會打印出錯誤信息，函數調用棧如下圖：
OK ，這樣我們就能在發布版本的程序中，準確的定位到哪個函數出了問題，所以發布程序時，一定要記得生成pdb、map文件，不然客戶運行出錯的話，你不死也殘！
