1.sx
sx* 命令用来控制被调试的程序发生某个异常或特定事件时，调试器要采取的动作
sx 命令显示当前进程的异常列表和所有非异常的事件列表，并且显示调试器遇到每个异常和事件时的行为。
sxr 命令将所有异常和事件过滤器的状态重设为默认值。命令被清除、中断和继续选项被重设为默认值，等等。
sx这个命令的输出信息可以分为三个部分：
第一部分是事件处理与相应处理模式的交互，第二部分是标准的异常交互和处理行为，最后一部分是用户自定义的异常交互和处理行为
以下面为例，我们先输入sxr再输入sx看下默认的处理行为都是怎么样的:
0:000> sxr
0:000> sxr sx state reset to defaults 0:000> sx ct - Create thread - ignore et - Exit thread - ignore cpr - Create process - ignore epr - Exit process - ignore ld - Load module - output ud - Unload module - ignore ser - System error - ignore ibp - Initial breakpoint - ignore iml - Initial module load - ignore out - Debuggee output - output av - Access violation - break - not handled asrt - Assertion failure - break - not handled aph - Application hang - break - not handled bpe - Break instruction exception - break bpec - Break instruction exception continue - handled eh - C++ EH exception - second-chance break - not handled clr - CLR exception - second-chance break - not handled clrn - CLR notification exception - second-chance break - handled cce - Control-Break exception - break cc - Control-Break exception continue - handled cce - Control-C exception - break cc - Control-C exception continue - handled dm - Data misaligned - break - not handled dbce - Debugger command exception - ignore - handled gp - Guard page violation - break - not handled ii - Illegal instruction - second-chance break - not handled ip - In-page I/O error - break - not handled dz - Integer divide-by-zero - break - not handled iov - Integer overflow - break - not handled ch - Invalid handle - break hc - Invalid handle continue - not handled lsq - Invalid lock sequence - break - not handled isc - Invalid system call - break - not handled 3c - Port disconnected - second-chance break - not handl

[3]利用windbg分析dump文件
来源: 互联网 发布时间: 2013-11-19
windbg是windows下一个分析调试的工具，功能非常强大。这里主要记录利用windbg来分析windows蓝屏时所产生的内存转储文件*.dmp。
1，下载：
http://www.microsoft.com/whdc/devtools/debugging/default.mspx
2，配置symbol path：
windows程序在编译生成后，会产生一些.exe,dll文件。同时也会用到一些symbol文件，这些文件包含全局变量，局部变量等信息。在调试不同的系统的时候，用到的symbol是不同的，而且这些文件会很大，如果下载安装会占用很大的硬盘空间。如果下载，在上面提供的地址也可以下载。微软还提供了一个网络上的symbol服务器。其网络地址是：http://msdl.microsoft.com/download/symbols，设置symbol时可以在打开windbg后，file->symbol file path 设置如下：其d:\temp 是本地缓存的目录：SRV*d:/temp/*http://msdl.microsoft.com/download/symbols。也可以用命令如下设置：
set _NT_SYMBOL_PATH=srv*DownstreamStore*http://msdl.microsoft.com/download/symbols
利用windbg分析dump文件（二）基本调试1，打开dump文件，在正确设置了symbol路径后，会有如下的显示：
Microsoft (R) Windows Debugger Version 6.5.0003.7
