Re: Comparing DateTime ?

Thanks for the reply

here 's the code for comparing 2 dates

int hour = 0;
    int min = 0;
    int sec = 0;

    int Month=0;
    int Day = 0;
    int Year = 0;
    std::string strFirstDate="23:34:22 1 21 2008";// (HH:MM:SS Month
Date Year )
    std::string strSecondDate="23:34:22 6 12 2007";
    time_t rawtime;
    struct tm * FirstTime;
    struct tm * SecondTime;
    time ( &rawtime );
    sscanf(strFirstDate.c_str(), "%d:%d:%d %d %d %d", &hour, &min, &sec,
&Month, &Day, &Year);

    FirstTime = localtime ( &rawtime );

    FirstTime->tm_hour = hour;
    FirstTime->tm_min = min;
    FirstTime->tm_sec = sec;
    FirstTime->tm_mon = Month;
    FirstTime->tm_mday = Day;
    FirstTime->tm_wday = ( Year - 1900 );

    time_t newTime = mktime(FirstTime );

    time ( &rawtime );
    SecondTime = localtime ( &rawtime );

    sscanf(strSecondDate.c_str(), "%d:%d:%d %d %d %d", &hour, &min,
&sec, &Month, &Day, &Year);

    SecondTime->tm_hour = hour;
    SecondTime->tm_min = min;
    SecondTime->tm_sec = sec;
    SecondTime->tm_mon = Month;
    SecondTime->tm_mday = Day;
    SecondTime->tm_wday = ( Year - 1900 );

    time_t existingTime = mktime(SecondTime);

    if (difftime(newTime,existingTime) > 0)
    {
        MessageBox(_T("First date is greater then Second Date"));
    }
    else if (difftime(newTime,existingTime) == 0)
    {
        MessageBox(_T("First date and Second Date are equal"));
    }
    else if (difftime(newTime,existingTime) < 0)
    {
        MessageBox(_T("First date is smaller then Second Date"));
    }

well I tried the same thing with ColeDateTime .... and it worked fine
for me .....

But was not able to figure out y the above code failed in comparing 2
datetime
