Hello experts,

I can probably test this by myself but I have no time for it so here's my question:

If I set an integer variable in the code of a windows service project type and increment or decrement its value according to a timer event, will I get the modified value when the timer fires the next time?

Thank you

Do you mean change the value when the timer event fires? Yes, the value will be different the next time the event fires, as long as the variable is defined outside the scope of the timer event (i.e. private variable to the service class, not declared internally in timer event method)

So if I have an integer called i whose value is 0, I increment it by one in the code. There's a timer event that fires say every 10 minutes, after half an hour the variable i becomes 3 right?

Thanks Nightman

Yes, that is correct. Like I said, the key thing here is the scope - as long as the variable is defined outside of the delegate for the timer it will work fine. If it is defined inside the delegate it will be re-initialised every time the timer fires.
