[RESOLVED] Calculating 2 times

[ukjock]

I want to calculate the difference from now till the top of the next hour i.e.

12:00:00 pm
minus
11:10:23 am

I have tried the following:

Plushour = DateTime.Now.AddHours(1)
        Dim span As TimeSpan = Plushour.Subtract(DateTime.Now)
        lbltime_countdown.Text = Format(span.Hours, "00") & ":" & Format(span.Minutes, "00") & ":" & Format(span.Seconds, "00")

Unfortunately the plus hour, adds an hour to the current time so my response is always -01:00:00 is there anyway to set it so that I can simply add an hour to the current time and keep the minutes and seconds to 00??

Thanks in advance

Kind Regards

Chris

You need to subtract the current time from the target time... below is an example that gets the next full hour after the current time, then displays how many minutes and seconds are left over until that time hits. It uses two timespans, the first gets the current hour and adds 1, the second is a timespan of the current hours, minutes, and seconds. Then the resulting timepan is the difference when subtracting the two....

'timespan representing the next full hour past the current time
        Dim TargetTime As New TimeSpan(Date.Now.Hour + 1, 0, 0)
        'timespan of the current time
        Dim CurrentTime As New TimeSpan(Date.Now.Hour, Date.Now.Minute, Date.Now.Second)
        'subtracts current time from target time, displays result (time until the next hour)
        Dim ResultTime As TimeSpan = TargetTime.Subtract(CurrentTime)
        MessageBox.Show(ResultTime.Hours & ":" & ResultTime.Minutes & ":" & ResultTime.Seconds)

If you are wanting to set it at a particular time of the day, then modify the first timespan with the hour you want to set it on... ex.. 12 noon would be Timespan(12,0,0), 5pm would be (17,0,0), etc...
