Timer driving me nuts

[John]

Hi

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

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. Can you show me where this limitation of
the System.Windows. Forms.Timer control is documented (beacuse I can't find
it)?

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.

Timer1.Interva l = 60000 '1 minute interval
Timer1.Start ()

Timer1.Interva l = 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_MAXI MUM. That constant
is defined in winuser.h as 0x7FFFFFFF

There must be something else that's wrong in this case. Show your code

Thanks again everyone.

Can we see the code?

I found it in MSDN:
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?

I also don't know why, but it is documented this way.
Maybe a microsoft employee can explain this?
