Execute specified function every X seconds

Question

I have a Windows Forms application written in C#. The following function checks whenever printer is online or not:

public void isonline()
{
    PrinterSettin         


        

Answer 1

Use System.Windows.Forms.Timer.

private Timer timer1; 
public void InitTimer()
{
    timer1 = new Timer();
    timer1.Tick += new EventHandler(timer1_Tick);
    timer1.Interval = 2000; // in miliseconds
    timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
    isonline();
}

You can call InitTimer() in Form1_Load().
