Can we use timer control in a general class?

I want to implement a timer in a class.

What I have done is

I have created the timer as Timer timertimeElapse;

In the constructor, I typed the following two lines

timertimeElapse = new Timer();
     timertimeElapse.Tick += new EventHandler(timerTimeOut_Tick);

I have made the event in the same class scope

private void timerTimeOut_Tick(object sender, EventArgs e)
{
}

This is not working :( Will you please suggest a way how to use timer event in the class? (not in the form)

Hi,

Is the constructor being called on the main thread of a windows forms application? It's important that it is as the System.Windows.Forms Timer will not raise tick events unless the thread is running a message loop.

The two other timers, System.Threading.Timer and System.Timers.Timer, don't need a message loop, and you may need to use one of those.

This simple modification to your code will determine if a message loop in running on the calling thread.

System.Diagnostics.Debug.Assert(
  System.Windows.Forms.Application.MessageLoop,
  "Cannot start Forms.Timer on thread without a message loop");
timertimeElapse = new Timer();

You need to set the interval as mentioned before and you also need to start the timer otherwise it won't do anything.

You need to specify a timer interval, and you also need to add a call to start the timer. Here's a sample of what you need to add:

timertimeElapse.Interval = 1000; // A 1 second timer

timertimeElapse.Start();
