COleDateTime/COleDateTimeSpan in dialogs & manipulation

Question

I have read until my head started spinning. I can not figure out how COleDateTime works with dialogs. I can add the current date and time to my dialog, but I want to know how to manipulate the date/time (get the current date/time and set it to another date/time and then display it). How do I proceed or where can I learn how to do this?

If I have m_dtDate.GetDay() what is the proper way(format) to display m_dtDate in an edit control(m_wndDate)???

I don't think this is the only or even necessarily the best way to encapsulate a date, but it's really straightforward from what I see.

GetCurrentTime gets the current time. SetDateTime sets it. Operator +, -, +=, -=, means you can add them together. The Format method lets you build a formatted version for display.

I read this last night, but I was so tired I couldn't wrap my brain around it. It makes a little more sinse today. What format do I need to display the result of (m_dtDate.GetDate()) in any edit box control???

I created a variable m_oleMyDate of type COleDateTime in my ...View.h file and then initialized it to (COleDateTime::GetCurrentTime()) in my View .cpp file.

Next, I created three variables of type int (nYear, nMonth, nDay) and then set the variables with the current month day and year as follows:

nYear = m_oleMyDate.GetYear();
nMonth = m_oleMyDate.GetMonth();
nDay = m_oleMyDate.GetDay();

I then created a function to manipulate the date for any purpose.

Finally, I used m_oleMyDate.SetDate(nYear, nMonth, nDay) to display my new date.

Thanks for the help
