Timer driving me nutsHi
I have a timer on my form. The problem is no matter how large an interval I set, the timer_tick event always gets called very fast. What am I doing wrong? Thanks Regards Hey John,
R u setting the timer interval at runtime after starting the timer? If that is the case, set the timer interval before starting the timer. Hope it helps.

fast almost like 1 second. I am running my process in the Timer_Tick event.

If I remember correctly the Timer.Interval will accept a large numer, like 600000, however the only valid numbers are 0 through ~32000. Interval is defined in milliseconds. -Boo Show quoteHide quote > I have set it at design time and it currently stands at 600000. Still > too fast almost like 1 second.

My only problem now is to set the interval to about 5
minutes. If the highest interval the timer can take is 32000 (32 seconds?) then how does one get round it? Thanks again everyone.

The interval can be between 1 and 64,767, inclusive, which means that even the longest interval will not be much longer than one minute (about 64.8 seconds). now if you need a larger timer try the following. Add a static variable. rease the variable each time you enter the sub. When you have the seconds you need (if - end if) do your stuff Jan Show quoteHide quote "John" <John@nospam.infovis.co.uk> schreef in bericht news:OrncNP3yGHA.5048@TK2MSFTNGP05.phx.gbl... > Got it now thanks.

Both of the following works fine on my machine: Timer1.Interval = 60000 '1 minute interval Timer1.Start() Timer1.Interval = 300000 '5 minute interval Timer1.Start() According to the docs for SetTimer (that System.Windows.Forms.Timer uses) the maximum value for the interval is USER_TIMER_MAXIMUM. That constant is defined in winuser.h as 0x7FFFFFFF There must be something else that's wrong in this case. Show your code /claes Show quoteHide quote "John" <John@nospam.infovis.co.uk> wrote in message news:OrncNP3yGHA.5048@TK2MSFTNGP05.phx.gbl... > Got it now thanks.

There are 2 types of timers available: 1. The timer control (System.Windows.Forms.Timer) 2. The timer class (System.Timers.Timer) The first one is a control, and has a limititation of 64,767 seconds. The second one is a class, and does not have this limitation.

As I posted below I successfully used System.Windows.Forms.Timer with a 5 minute (i.e. 300 seconds) timeout. Can you show me where this limitation of the System.Windows.Forms.Timer control is documented (beacuse I can't find it)? /claes Show quoteHide quote "Theo Verweij" <tverw***@xs4all.nl> wrote in message news:%23yXHhd6yGHA.1292@TK2MSFTNGP03.phx.gbl... >I think there is a misunderstanding between the readers. > There are 2 types of timers available: > 1.

http://msdn2.microsoft.com/en-us/library/xy0zeach.aspx It actually says that the timer interval is limited to max 64 seconds. Looks incorrect to me though. Setting it to 2 minutes correctly fires the Tick event every 2 minutes as expected in my text application. And the underlying API (SetTimer) doesn't have any 64 sec limitation so why would the Timer class have it? /claes Show quoteHide quote "Claes Bergefall" <louplou@nospam.nospam> wrote in message news:eWgUEMEzGHA.2640@TK2MSFTNGP06.phx.gbl... > The first is a class too... > > As I posted below I successfully used System.Windows.Forms.Timer with a 5 > minute (i.e. 300 seconds) timeout.

Maybe a microsoft employee can explain this?
