Default Timer Or Thread? (c#)

hi, please help me.
I want to run timer (or thread) that checks every 5 sec something in my code and then doing corresponding action.
At the same time the methods must be invoked normally.
It means that it is a kind of interrupt every 5 sec while running the program.

thanks
Koby

Hi Koby,

Am new at this. but since you used the word "interrupt", I am assuming that you dont want to be blocked. This is what suggest. I think thread should do the job for you.

You have your main thread and you create another Checker thread.

The checker thread does whatever you want to check for and then sleeps for 5 seconds. I am assuming that sleep() in C# is non-blocking.

Alternate idea ...

use a timer, which when expires will pass the control to something like OnTimerExpired() which will do your checking ... but since I havent done much with timers I am not sure if it will be as it sounds

This is a typical solution for a Timer and not a constant thread (though both are technically possible). if you are using a windows form then you can simply drag a timer on the form and implement the Timer.Tick event. There are other types of timer in the framework as well. The benefits of using the System.Windows.Forms.Timer in a Windows Form is that the form will get priority for refreshing, instead of the Timer event.

This gives a good explaination of the Forms Timer... http://www.c-sharpcorner.com/controls/timer.asp

Thread t1=new Thread(f1); //
// in the constructor or form load event
    t1.Start();

private void f1()
{
while(1==1)
{
// Call the requred function;
Thread.Sleep(1000/12); // or pass any value of time in microsec.
}
}
