Create a timer object for one seconds interval.The following example instantiates a object that fires its Timer.Elapsed event every two seconds sets up an event handler for the event, and starts the timer. The class is intended for use as a server-based or service component in a multithreaded environment and it has no user interface and is not visible at runtime. Unlike the, the events are effectively queued - the timer doesn't wait for one event to have completed before starting to wait again and then firing off the next event. The Start and Stop methods of which are similar to changing the Enabled property. Instead of a Tick event, it has the Elapsed event. This method does not execute in the thread that created the timer it executes in a separate thread pool thread that is provided by the system. Timer AutoReset property gets or sets a Boolean indicating whether the Timer should raise the Elapsed event only once (false) or repeatedly (true).Ĭallback represents the method that handles calls from a Timer. Timer Interval property gets or sets the time, in milliseconds, before the Tick event is raised relative to the last occurrence of the Tick event. The Elapsed event is raised if the Enabled property is true and the time interval (in milliseconds) defined by the Interval property elapses. Timer Elapsed event occurs when the interval elapses. MyTimer.Tick += new EventHandler(TimerEventProcessor) Timer Tick event occurs when the specified timer interval has elapsed and the timer is enabled. Private void button2_Click(object sender, EventArgs e) Private void button1_Click(object sender, EventArgs e) Private void Form1_Load(object sender, EventArgs e) The application stops writing to the text file once the Stop button is clicked. The application will write a line to a text file every 1 second once the Start button is clicked. The program has two buttons, Start and Stop.

The following C# program shows how to use a timer to write some text to a text file each seconds. The Timer control have included the Start and Stop methods for start and stop the Timer control functions. Private void timer1_Tick(object sender, EventArgs e) Here we set the timer interval as 1000 milliseconds, that means one second, for displaying current system time in Label control for the interval of one second. In order to develop this program, we need a Timer Control and a Label Control. In the following program we display the current time in a Label Control. So before running the program we have to set the Enabled property is True, then only the Timer Control starts its function. īy default the Enabled property of Timer Control is False. For example, if we want to set an interval of 1 minute we set the value at Interval property as 60000, means 60x1000. That is, one second is equal to 1000 milliseconds. The Timer Control allows us to set Interval property in milliseconds. We can control programs with Timer Control in millisecond, seconds, minutes and even in hours. We have to use Timer Object when we want to set an interval between events, periodic checking, to start a process at a fixed time schedule, to increase or decrease the speed in an animation graphics with time schedule etc.Ī Timer control does not have a visual representation and works as a component in the background. We require Timer Object in many situations on our development environment. With the Timer Control we can raise events at a specific interval of time without the interaction of another thread.

The Timer Control plays an important role in the development of programs both Client side and Server side development as well as in Windows Services.
