  I've created a windows application which shows change of label text.I use loop to increment value from 1 to 100 and that shows in a label.For showing that I use Application.DoEvents() method.But I need to cancel that operation after clicking on close button.But after I clicking on close button it only close form but not the operation.Also it need to click twice on the "Close" button.Single click doesn't work. namespace TestApp { public partial class FrmTest : Form { public FrmTest() { InitializeComponent(); } private void btnClose_Click(object sender, EventArgs e) { this.Close(); } private void btnProcess_Click(object sender, EventArgs e) { for (int i = 1; i <= 100000; i++) { this.lblText.Text = i.ToString(); Application.DoEvents(); //System.Threading.Thread.Sleep(200); } btnMsg.MouseClick += new MouseEventHandler(btnMsg_Click); } private void btnMsg_Click(object sender, EventArgs e) { MessageBox.Show(sender.ToString()); MessageBox.Show(e.ToString()); } } }
