Showing time left

Given a future date/time variable (function input), how can I output how much time is left in this format...

"2 years, 3 months, 4 days, 11 hours, 20 minutes and 10 seconds remaining."

To go 1 step further, I would like to have several boolean input variables for the function, like...
bShowYears as boolean, bShowMonths as boolean, bShowDays as boolean

So if they turn bShowYears to false then the "months" would reflect this and the out put would be (using the same example)....

"27 months, 4 days, 11 hours, 20 minutes and 10 seconds remaining."

Please provide sample code in vb.net. Thanks

I started on this but ran out of time. The function I wrote below will show you the time remaining in each format (years, months, days, hours, minutes, seconds). for example if you have a 48 hour difference, it will show 0 years, 0 months, 2 days, 48 hours instead of 2 days, 0 hours... if you get what i mean.

I know you wanted more, but I have to run. so here is the concept, you can tweak it up.
 
Public Function TimeRemaining(ByVal strDate As Date, ByVal bShowYears As Boolean, ByVal bShowMonths As Boolean, ByVal bShowDays As Boolean) As String
        Dim strResult, strYearDiff, strMonthDiff, strDayDiff, strHourDiff, strMinuteDiff, strSecondDiff As String
        strResult = ""

        strYearDiff = DateDiff(DateInterval.Year, DateTime.Parse(strDate), DateTime.Now)
        strMonthDiff = DateDiff(DateInterval.Month, DateTime.Parse(strDate), DateTime.Now)
        strDayDiff = DateDiff(DateInterval.Day, DateTime.Parse(strDate), DateTime.Now)
        strHourDiff = DateDiff(DateInterval.Hour, DateTime.Parse(strDate), DateTime.Now)
        strMinuteDiff = DateDiff(DateInterval.Minute, DateTime.Parse(strDate), DateTime.Now)
        strSecondDiff = DateDiff(DateInterval.Second, DateTime.Parse(strDate), DateTime.Now)

        If bShowYears = True Then strResult = strYearDiff & " Years  "
        If bShowMonths = True Then strResult = strResult & strMonthDiff & " Months  "
        If bShowDays = True Then strResult = strResult & strDayDiff & " Days  "
        strResult = strResult & strHourDiff & " Hours  " & strMinuteDiff & " Minutes  " & strSecondDiff & " Seconds"
        Return strResult
    End Function

To make it work how you want you can make it only query the seconds difference and just use math to calculate the rest

Your code doesn't do what it should. I need it to break it down further. Can anyone assist please?

To simplify, given 2 date/times, return the time left between them in this format....

x years, x months, x weeks, x days, x hours, x minutes, x seconds

Thanks
