你好，谢谢你第一个回复，其实Dump文件产生了同样的问题，我通过MiniDumpWriteDump函数来写dump文件，异常程序死机后，产生出.dmp文件。 我下载了WinDbg软件(版本：WinDbg:6.11.0001.404.X86)，设置了pdb文件路径为我VC的*.pdb文件路径(其实就是VC的Output路径)，然后在windbg中OpenFile--》Open Crash Dump，下面就是结果：This dump file has an exception of interest stored in it. The stored exception information can be accessed via .ecxr.

谢谢，你的回复，前几天出差去现场解决问题，没有及时回帖请谅解。 问题还是没有解决。 当前已经设置了，symbol的路径为：D:\Windows\XP\Symbols\dll;E:\Code\MASU 0509\publib 其中D:\Windows\XP\Symbols\dll为我从微软网站下载的symbols大包，然后open dump得到： Unable to deliver callback, Unable to deliver callback, 00 WARNING: Whitespace at start of path element WARNING: Non-directory path: 'WARNING: Non-directory path: 'E:\Code\MASU 0509\publib\masud.pdbE:\Code\MASU 0509\publib\masud.pdb' ' Loading Dump File [E:\Code\MASU 0509\publib\masud.dmp] Loading Dump File [E:\Code\MASU 0509\publib\masud.dmp] User Mini Dump File: Only registers, stack and portions of memory are available User Mini Dump File: Only registers, stack and portions of memory are available WARNING: Non-directory path: 'WARNING: Non-directory path: 'E:\Code\MASU 0509\publib\masud.pdbE:\Code\MASU 0509\publib\masud.pdb' ' Symbol search path is: Symbol search path is: E:\Code\MASU 0509\publib\;D:\Windows\XP\Symbols\dll\;E:\Code\MASU 0509\publib E:\Code\MASU 0509\publib\;D:\Windows\XP\Symbols\dll\;E:\Code\MASU 0509\publib Executable search path is: E:\Code\MASU 0509\publib\masud.pdb Executable search path is: E:\Code\MASU 0509\publib\masud.pdb Windows XP Windows XP Version 2600Version 2600 (Service Pack 3) (Service Pack 3) MP MP (2 procs) (2 procs) Free x86 compatible Free x86 compatible Product: Product: WinNtWinNt, suite:, suite: SingleUserTS SingleUserTS Machine Name:Machine Name: Debug session time: Tue Jun 7 18:06:54.000 2011 (GMT+8) Debug session time: Tue Jun 7 18:06:54.000 2011 (GMT+8) System Uptime: not available System Uptime: not available Process Uptime: 0 days 0:00:02.000 Process Uptime: 0 days 0:00:02.000 ................................................................................................................................ ......................................

其中我死机的地方如何用以上信息定位:DVRBridgeThreadProc+0x26 [e:\code\masu 0509\dvrlink\src\dvrmanager.cpp @ 28]
估计造成死机的代码为：
DWORD WINAPI DVRBridgeThreadProc(LPVOID lpParameter)
{
CDVRManager *pThread;
pThread = (CDVRManager *)lpParameter;
pThread->Execute();
ExitThread(0);
return 1;
}
int CDVRManager::Execute(void)
{
int iChannelNum = m_pMainData->m_pConfigInfo->iChannelNum;
DVRCHANNELINFO *pChannelInfo;
char* szTmpBuf = NULL;
strcpy(szTmpBuf, "1111");/*在这里0地址访问，造成死机*/
while(!m_Terminated)
{
。
}
}
若是我哪里没有写清楚，麻烦及时提问，谢谢各位windows系统高手。
strcpy(szTmpBuf, "1111");/*在这里0地址访问，造成死机*/
你都没分配内存，如何拷贝字符串啊？
char* szTmpBuf = NULL;
strcpy(szTmpBuf, "1111");/*在这里0地址访问，造成死机*/
这里,还问是什么问题
char* szTmpBuf = NULL;
strcpy(szTmpBuf, "1111");/*在这里0地址访问，造成死机*/
这种零地址改写，大街上随便找个人都能看出来啊！这个代码当然是用于实验。
估计是没有看我的问题。请教windows系统级专家，我问的问题是：
应用dbghelp.DLL捕捉到异常后，生成了dump文件，如何用dump文件通过windbg工具和符号表来定位windows程序死机的位置。
现在用windbg工具打开了dump文件，并且制定了符号表文件路径。应执行了!analyze -v的命令，仍旧不能通过符号表得出对应死机的行数。
得出的知识机器码的偏移：DVRBridgeThreadProc+0x26
因为符号表没有发挥作用。(可以看看我操作步骤的描述)所以这里请教windows系统级专家，如何通过dump文件、符号表来定位问题出现的行数。
这个问题在这个论坛出现个多次，始终没有解答，麻烦有高手终结！
参考一下这个，希望对你有帮助~
如此即可！
因为我也出现了这个问题，所以经过了测试，这个方法可行。
