タイマーで一定間隔で処理を行う．

http://www.atmarkit.co.jp/fdotnet/dotnettips/372formstimer/formstimer.html

		private void button11_Click(object sender, EventArgs e)
		{
			timer = new Timer();
			timer.Tick += new EventHandler(hoge1);
			timer.Tick += new EventHandler(hoge2);
			timer.Interval = 1000;
			timer.Enabled = true;
		}

		private void hoge1(object sender, EventArgs e)
		{
			Console.WriteLine(DateTime.Now);
		}

		private void hoge2(object sender, EventArgs e)
		{
			Console.WriteLine(DateTime.Now);
		}

結果は，
2007/01/26 21:35:40
2007/01/26 21:35:40
2007/01/26 21:35:41
2007/01/26 21:35:41
つまり，hoge1とhoge2がほぼ同時で1000msecごとに呼び出される．
