之前碰到论坛里有几个好友,说程序不时的崩溃,什么xxoo不能read的!

如果光要是这个内存地址,估计你会疯掉~~

所以分享一下基本的调试技巧,需要准备的工具有WinDbg + VC6.0,

下面是自己整理的一份自动生成DUMP文件的源代码,只需要添加到工程即可,源代码如下:

MiniDump.h
MiniDump.cpp


<具体请参考附件SRC中,太大就不贴了>

1、在CXXDlg::OnInitDialog()中添加这样一段:
  1. BOOL CTestDlg::OnInitDialog()
  2. {
  3.         CDialog::OnInitDialog();
  4.    
  5.         // ......
  6.         SetUnhandledExceptionFilter(CrashReportEx);
  7.         HMODULE        hKernel32;

  8.         // Try to get MiniDumpWriteDump() address.
  9.         hDbgHelp = LoadLibrary("DBGHELP.DLL");
  10.         MiniDumpWriteDump_ = (MINIDUMP_WRITE_DUMP)GetProcAddress(hDbgHelp, "MiniDumpWriteDump");
  11.         //        d("hDbgHelp=%X, MiniDumpWriteDump_=%X", hDbgHelp, MiniDumpWriteDump_);
  12.        
  13.         // Try to get Tool Help library functions.
  14.         hKernel32 = GetModuleHandle("KERNEL32");
  15.         CreateToolhelp32Snapshot_ = (CREATE_TOOL_HELP32_SNAPSHOT)GetProcAddress(hKernel32, "CreateToolhelp32Snapshot");
  16.         Module32First_ = (MODULE32_FIRST)GetProcAddress(hKernel32, "Module32First");
  17.         Module32Next_ = (MODULE32_NEST)GetProcAddress(hKernel32, "Module32Next");
  18. }
复制代码
下面是工程中的测试代码:
  1. class CTestDlg : public CDialog
  2. {
  3. // Construction
  4. public:
  5.         CTestDlg(CWnd* pParent = NULL);        // standard constructor

  6.         void Fun1(char *pszBuffer);
  7.         void Fun2(char *pszBuffer);
  8.         void Fun3(char *pszBuffer);
  9. };
复制代码
  1. void CTestDlg::Fun1(char *pszBuffer)
  2. {
  3.         Fun2(pszBuffer);
  4. }

  5. void CTestDlg::Fun2(char *pszBuffer)
  6. {
  7.         Fun3(pszBuffer);
  8. }

  9. void CTestDlg::Fun3(char *pszBuffer)
  10. {
  11.         pszBuffer[1] = 0x00;
  12. }
复制代码
我们在双击确定按钮时的响应代码如下:
  1. void CTestDlg::OnOK()
  2. {
  3.         // TODO: Add extra validation here
  4.         Fun1(NULL);
  5. }
复制代码


2、设置VC编译选项,勾选生成MAP和Debug Info、Progma Datebase:

3、将编译生成的Release目录中的pdb、map文件保存起来,以后调试会用到:
2.jpg


4、运行程序,单击确定按钮出现异常后自动重启,并创建一个Log文件夹,里面生成dump文件:

5、我们打开WinDbg,设置一下相关路径
    A、
设置pdb路径(File \ Symbol File Path)
    PDBPath.jpg
    B、设置源代码路径( File \ Source File Path )
    SourcePath.jpg
    C、设置Exe路径( File \ Image File Path )
    ExePath.jpg

6、用WiinDbg打开dump文件(File \ Open Crash Dump)
5.jpg


7、输入命令!analyze -v,等待几秒后会打印出错误信息,函数调用栈如下图:

  2. Copyright (c) Microsoft Corporation. All rights reserved.

OK ,这样我们就能在发布版本的程序中,准确的定位到哪个函数出了问题,所以发布程序时,一定要记得生成pdb、map文件,不然客户运行出错的话,你不死也残!
