set up timer start 15 sec past minute

[Guest]

Hi, All,

My question is how to set up timer start 15 sec past minute. It always start
15
sec past minute. For example, if current time is 8:30:45, the timer starts on
8:31:15 am; if current time is 8:00:00, the timer starts on 8:00:15; if
current time is 8:55:15, the timer starts on 8:55:15, if current time is
8:59:00, the timer starts on 8:59:15 ..., so the timer always starts 15
seconds past minute, can anyone help this out?

Thanks in advance

Hello martin1,

why not just have yer timer fire every half second and the first thing you
check is the current time.

Martin,

What timer are you using?

There are at least three in System.Net

Hi, Cor,

I use form timer (System.Windows.Forms.Timer), any more advice?

Thanks

Martin,

Than you can in my idea set the milliseconds after that you have extracted
the seconds (not the milliseconds) for that from the datetime.

Your maximum is in my idea 60 *1000.

I hope this helps,

Thank you. Cor,

So the logic is retrive current second, if = 15 sec, then start timer

The code look likes:

Dim moment As New System.DateTime
Private Shared myTimer As New System.Windows.Forms.Timer()

Dim second As Integer = moment.Second

if second = 20 then
myTimer.Interval = 60000
myTimer.Start()
end if

Is this correct?

Thanks,

To get 15 seconds after midnight, use the following

Dim ts As TimeSpan = Now.Date.AddDays(1).AddSeconds(15) - Now

All the timer controls in dotNet can set their interval using a timespan
object.

Martin,

No of course not. Something as

Dim moment As New System.DateTime
Private Shared myTimer As New System.Windows.Forms.Timer()

Dim second As Integer = moment.Second

if second < 16 then
myTimer.Interval = Cint(14 * 1000)
else
myTimer.Interval = CInt(second * 1000)
end if
myTimer.Start()

I did not check this, but something as this,
