Question

I am developing an application where i need the following requirement:

Suppose i have a button and a label (initially visibility set to false) in my form, and user clicks on the button, then the label should be displayed with some text that i assign to the label in the button click. But this label should be displayed only for some time, say some 3 secs and then it should automatically go invisible. For this if i gave:

private void button1_Click(object sender, EventArgs e)
    {
     label1.Visible=true;
     label1.Text= "Magic";
     Thread.Sleep(3000);
     label1.Visible=false;
    }

This code does not help the purpose. What is the approach to do it?

Answer 1

Try replacing the last two lines of your method with this:

System.Windows.Forms.Timer timer = new System.Windows.Forms.Timer();
timer.Interval = 3000;
timer.Tick += (source, e) => {label1.Visible = false; timer.Stop();};
timer.Start();

Using Thread.Sleep() is never a good idea in WinForms; use timers instead.
