Question

I am setting a timer interval of (Hours):

Timer1.Interval = ((CInt(ComboBox24.SelectedItem.ToString()) * 60 * 60) * 1000)

And then calculating the next DateTime that the ticks event will fire using:

MessageBox.Show("Next Timer Will Occur At: " & New Date(DateTime.Now.Ticks + Timer1.Interval))

Each time I call the MessageBox it shows me that the next event will fire now (Exact date, hour, minute, second).

I can’t see where I have gone wrong here as when I simply messagebox’d the calculation it clearly showed separate numbers (ticks) & by a large amount.

Answer 1

Ticks aren’t the same as milliseconds. Use Date.Now.TotalMilliseconds. Or, even better, AddMilliseconds:

MessageBox.Show("Next Timer Will Occur At: " & DateTime.Now.AddMilliseconds(Timer1.Interval))
