Suppose my date is 31 November 2007 and I would like to add two months to it..

The problem is that a month does not have a constant value.

DavidCrow wrote:

Also, suppose you wanted to add three months to the date. Since February does not have 31 days, do you stop at February 28, or go 3 days into March? If the latter, it looks odd since March would then be four months away.

But CPallini's answer is the way to go I suppose (didn't implement it yet).

COleDateTime AddMonths( const COleDateTime dt, const int nMonthsToAdd )
{
    COleDateTime    dateTemp;
    int             nMonth = (dt.GetMonth() - 1) + nMonthsToAdd,
                    nYear  = dt.GetYear(),                    
                    x = 0;
 
    dateTemp.SetStatus(COleDateTime::invalid);
 
    while (dateTemp.GetStatus() == COleDateTime::invalid && x < 4)
    {
        dateTemp.SetDateTime(nYear + (nMonth / 12), 
                             (nMonth % 12) + 1, 
                             dt.GetDay() - x, 
                             dt.GetHour(),
                             dt.GetMinute(),
                             dt.GetSecond());
 
        x++;
    }
 
    return dateTemp;
}

1. To get the wide character binary value, I use L"MÍST" and use debug mode to watch its internal buffer in Visual Studio.

To get the multibyte (UTF-8) binary value, I use WideCharacterToMultibyte API to convert L"MÍST" to multibyte value;

CPallini wrote:

Fine. Since wide chars are unsigned shorts, I'm sure you're also able to figure out how programmatically find the encoded values.

CPallini wrote:

but I think CP_UTF8 gives you have unmapped chars than Czech codepage (1250?))

How do you find the magic value numebr 1250, in some Windows header (.h) file?

hence no need for you.
