Timers not working when minimized - why?

[AndyGroom]

This is the first time I've come across this in 10 years of VB programming. If you have a timer on a form with an interval of say 100 and then minimise the running application, the timer stops firing. What's the logic behind that, and is there a way around it?

I've just created a new project, single form with a single timer on it (100 interval) with code

Private Sub Timer1_Timer()

Static intCtr As Integer

intCtr = (intCtr + 1) Mod 10
If intCtr = 0 Then
   Me.Caption = Time
End If

End Sub

When minimized the timer still fires.

Are you sure your timer is not being disabled in another part of your code?

It's weird, maybe it's a bug in XP because although the minimized caption on the taskbar doesn't change, if you float over it the floatover updates to show the time (in your example).

Er....dare I say this.....

"This behavior is by design."

Just joking. I did this:

Private Sub Timer1_Timer()
Label1.Caption = Now
End Sub

Timer interval set to 10000. I just minimized, waited 30 seconds or so, and found the time to have changed.
