The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

C++ MFC Visual Studio 2005 - CRT init issue

Asked by steenpat in Windows MFC Programming, Microsoft Visual C++.Net, C / C++ / C# Editors and IDEs

Tags:

I am doing a debug of my MFC project and an exception is being thrown multiple times before the dialog is loaded. After debugging and looking at the call stack the project is breaking in crt0dat.c part of c runtime library. According to the code snippet below pfBegin must not be null otherwise an exception is thrown, however the variable is null which is causing the exception. Unfortunately I'm not really sure why that is or what is causing it. Could this be a problem with the CRT having inconsistency issues? I'm also noticing a lot of bizarre memory leaks in the debug exe. Start Free Trial

#ifdef CRTDLL
void __cdecl _initterm (
#else  /* CRTDLL */
static void __cdecl _initterm (
#endif  /* CRTDLL */
        _PVFV * pfbegin,

        /*
         * walk the table of function pointers from the bottom up, until
         * the end is encountered.  Do not skip the first entry.  The initial
         * value of pfbegin points to the first valid entry.  Do not try to
         * execute what pfend points to.  Only entries before pfend are valid.
         */
        while ( pfbegin < pfend )
        {
            /*
             * if current table entry is non-NULL, call thru it.
             */
            if ( *pfbegin != NULL )
                (**pfbegin)();
            ++pfbegin;
        }
}
 
/***
* static int  _initterm_e(_PIFV * pfbegin, _PIFV * pfend) - call entries in
*       function pointer table, return error code on any failure
*
*Purpose:
*       Walk a table of function pointers in the same way as _initterm, but
*       here the functions return an error code.  If an error is returned, it
*       will be a nonzero value equal to one of the _RT_* codes.
*
*Entry:
*       _PIFV *pfbegin  - pointer to the beginning of the table (first
*                         valid entry).
*       _PIFV *pfend    - pointer to the end of the table (after last
*                         valid entry).
*
*Exit:
*       No return value
*
*Notes:
*       This routine must be exported in the CRT DLL model so that the client
*       EXE and client DLL(s) can call it.
*
*Exceptions:
*       If either pfbegin or pfend is NULL, or invalid, all bets are off!
