    Dim dt As Long = DateTime.Now
    Dim destdt As Long = dt + DateTime.TicksPerDay
    Log("start="&DateTime.Date(dt))
    Log("end="&DateTime.Date(destdt))

    Dim dt As Long = DateTime.Now
    Dim destdt As Long = dt + DateTime.TicksPerDay
    Log("start="&DateTime.Date(dt))
    Log("end="&DateTime.Date(destdt))

thank u Mr Don, yes that's to get the next date or day ... where i can put this code ? in a timer and what is the timer interval?

When you work with services you can avoid the use of the timer.
It's much easier to use StartServiceAt and schedule when the next service will start.

How to schedule a startserviceat everyday at Hour 24:01 ( midnight )

 

[James Chamblin]

Every time the service is run, schedule the next time in Sub Service_Start

 

[Straker]

And this is the code which calculates the next task (tomorrow at midnight + 1 minute)
It uses the standard DateUtils library

    Dim dateNow As Long = DateTime.Now
    Dim NextTask As Long
    Dim m As String
    Dim p As Period
    NextTask=dateutils.SetDateAndTime (DateTime.GetYear(datenow) ,DateTime.GetMonth (datenow),DateTime.GetDayOfMonth(datenow),0,1,0)
    p.Days =1
    NextTask=DateUtils.AddPeriod (NextTask,p)
    'In NextTask you have 'tomorrow' at midnight and 1 minute
    'The next code will Log the result (ok, probably was easier with a Format...
    m=DateUtils.GetDayOfWeekName(NextTask) &  " " & DateTime.GetDayOfMonth(NextTask) & " " & DateUtils.GetMonthName(NextTask) & " " & DateTime.GetYear(NextTask)
    m=m & "  " & DateTime.GetHour (NextTask) & ":" & DateTime.GetMinute(NextTask) & ":" & DateTime.GetSecond (NextTask)
    Log("NextTask:" & m)

Hello,
using your code, everytime I start the app, I've got a notification. How can I prevent it?

 

[Straker]

If you parse the code (place a breakpoint in activity start and the go on with F8) you'll see that in that demo I do a notification at every start. I know it's annoying but it was a good example. Just search the notify and cut the one you want to avoid. I don't have the code here now, so I cannot completely help you.

 

[imgsimonebiliato]

But do you mean the code above this thread?

 

[Straker]

But do you mean the code above this thread?

No, sorry (we're talking about similar things in 2 or 3 threads)

If you mean the code of post #7, it just evaluate the next task and doesn't call any notification.
Probably your code performs a notification at startup. Where are your notification? In the service? From the activity, are you calling the service with StartService or sStartServiceAt?

 

[imgsimonebiliato]

The notification is in a module. I start the service at the "FIRST TIME" of the Main Activity. But, if I close the app, and reopen it, the service start and also the notification

i attached a simple example explain all the problems..
