History: Callstack trace through OgreException out of IDE (for windows only)

            Only for windows.

I want trace the call stack when ogre throw OgreException outof VS IDE sometimes .
I can use the DBGHELPER.dll to walk through callstack and get the symbo information.
So, I Need to get the CONTEXT from the exception point.
But I can't get this form catch point As Ogre use std::exception that has not CONTEXT.
So I make a modify to ogre exception:
OgreException.h:
change 
{CODE(wrap="1", colors="c++")}#define OGRE_EXCEPT ....{CODE}
to 
{CODE(wrap="1", colors="c++")}#ifndef OGRE_EXCEPT
#define OGRE_EXCEPT ....
#endif{CODE}

I can make a custom version OGRE_EXCEPT in OgreConfig.h to provide call stack trace now.

In OgreConfig.h
add 
{CODE(wrap="1", colors="c++")}void DoExceptionCallStackTrace(const char* exception_description,const char* prefix_file_name);
#define OGRE_EXCEPT(num, desc, src) do{    Ogre::String temp=desc;    DoExceptionCallStackTrace(temp.c_str(),"Ogre exception");     throw Ogre::ExceptionFactory::create( Ogre::ExceptionCodeType<num>(), desc, src, __FILE__, __LINE__ );}while(0);

#ifdef _DEBUG
#    pragma comment(lib,"CallStackTraceD.lib")
#else
#    pragma comment(lib,"CallStackTrace.lib")
#endif{CODE}

CallStackTrace.lib include 
DoExceptionCallStackTrace and Konstantin Boukreev's Sym_Engine 
sym_engine.h coming from [http://www.codeproject.com/cpp/exception.asp|code project]

DoExceptionCallStackTrace function:
{CODE(wrap="1", colors="c++")}#include <windows.h>
#include <iostream>
#include <sstream>
#include <string>
#include <fstream>
#include <time.h>
#include <algorithm>

#include "sym_engine.h"

static std::string getTimeString()
{
    _tzset();
    char temp1[128];
    char temp2[128];
    // Display operating system-style date and time. 
    _strtime_s( temp1, 128 );
    _strdate_s( temp2, 128 );

    std::string result=temp2;
    result+=" ";
    result+=temp1;
    std::replace(result.begin(),result.end(),':','-');
    std::replace(result.begin(),result.end(),'/','-');
    return result;
}
void DoExceptionCallStackTrace(const char* exception_description,const char* prefix_file_name)
{
    CONTEXT c;
    memset(&c, 0, sizeof(CONTEXT));
    c.ContextFlags = CONTEXT_FULL; 

    __asm    call x 
    __asm x: pop eax 
    __asm    mov c.Eip, eax
    __asm    mov c.Ebp, ebp 
    __asm    mov c.Esp, esp 

    std::stringstream ss(std::ios::out);

    sym_engine::stack_trace(ss,&c,1);
    
    std::string file_name=prefix_file_name;
    static int id=0;
    id++;
    char buf[16];
    sprintf_s(buf,16," %04d ",id);
    file_name+=buf;
    file_name+=getTimeString();
    file_name+=".txt";

    std::fstream fs(file_name.c_str(),std::ios::out);
    fs<<exception_description;
    fs<<"\n";
    fs<<"call stack:\n";
    fs<<ss.str();
    fs.close();
}{CODE}

Now we run ogre out of IDE:
I can get a file named Ogre exception 0001 06-11-07 17-41-24.txt.
the file include:
{CODE(wrap="1", colors="c++")}Cannot locate resource varianceshadowcastervp.cg in resource group Effect or any other group.
