Errors in MFC apps

When I make an MFC application and something goes wrong during run time the app will often throw up an error that I didnt write, and doesnt appear anywhere in the source or string tables. There is one 'error' that I would like to remove completely. I am making a frontend for a (huge) database, but on running the program I get 'too many fields defined' error.

I would like to change the maximum limit or remove this error completely, as susrely the amount of maximum fields should depend on free resources etc, and is not constant.

Through further research I've found this is an error specific to access databases with more than 255 fields. Still if anyone knows how to remove this limit I'd appreciate it.

trap the error and look at the help files indicated for the error

Code:

try{

   ....dao operations here

}
catch( CDaoException* e )
{

    int iErrorCount = e->GetErrorCount();
    CString sMsg;
    CString sFullMsg;
    for( int i = 0; i < iErrorCount; i++
    {
         e->GetErrorInfo( i );
         sMsg.Format("Error code %d\nSource %s\nDescription %s\nHelpFile %s\nHelp Context %d",
          e->m_pErrorInfo->m_lErrorCode, e->m_pErrorInfo->m_strSource, e->m_pErrorCode->m_strDescription, ...m_strHelpFile, m_lHelpContext);
         sFullMsg += sMsg;
         sFullMsg += "\n";
     }

     MessageBox( sFullMsg );
     
}

Usually the associated help files jeterr...hlp have some pretty direct causes and I am able to fix my program from there...
