VC++ 6.0 errors

Apr 13th, 2007

Hi Everyone
I am new to vc++ 6.0 graphics programming. I am getting some errors of a program which i am trying to compile. i have added all the dependencies but not able to figure out why I am getting the following errors. Any suggestions.

Threading.cpp

my guess is that you forgot to include one or more header files. You should post the line(s) the compiler is complaining about.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.

All the errors are from these codes. I have no clue why? Thanks in advance.

std::map<std::string, std::map<std::string, c_PerformanceMeasurement> >::iterator iClass = mPerformances.find(Class);

   return iPerformance->second;
  }

does second.find(Name); return an iterator of the correct type? such as std::map<std::string, c_PerformanceMeasurement>::

looks like the variable mPerformances is a const map<...
you have to change ...>::iterator to ...>::const_iterator

Yes, it does. Actually, this code is developed by one of the developer of my company. The code runs ok in his machine. But when I try to compile it in my machine, it gives me error. I made sure that all the settings are same as his but same old errors. any suggestions?
