call Tick event when timer starts [duplicate]

Answer 1

Just create a method then call this from within your timer and also just before you start your timer.

private int counter; 
Timer t = new Timer(); 

private void InitializeTimer() 
{ 
    counter = 0; 
    t.Interval = 750; 

    DoMything();
    t.Tick += new EventHandler(timer1_Tick); 
    t.Enabled = true; 
} 

private void timer1_Tick(object sender, EventArgs e) 
{ 
    if (counter >= 3) 
    { 
        t.Enabled = false;                 
    } 
    else 
    { 
        //do something here 
        counter++; 
        DoMything();
    } 
} 


private void DoMything()
{
   //Do you stuff here
}

Answer 2

You could use a System.Threading.Timer.

This has a constructor that takes an initial wait period. Set this to zero and the timer will trigger the callback immediately then every interval you specify thereafter.

Timer stateTimer = new Timer(tcb, autoEvent, 0, 750);

Answer 3

The simplest way might be to initially set the Interval to something very small, then increase it in the Tick handler, or in a separate handler.

This will ensure the first "tick" occurs in the same manner as subsequent ticks, e.g. on its own thread, rather than in the context of the initialize method.

Answer 4

You can always call your method manually:

private void InitializeTimer()
{
    counter = 0;
    t.Interval = 750;
    t.Enabled = true;
    timer1_Tick(null, null);

    t.Tick += new EventHandler(timer1_Tick);
}
