MessageBox when closing form

Question

Upon closing the form by clicking on the button I created named 'Exit' I want it to display a messagebox asking the user "Are you sure you want to exit?" I don't know the syntax for it, can someone help me please? Thanks

Answer 1

if (MessageBox.Show("Are you sure?", "Exit Application?", 
    MessageBoxButtons.YesNo) == DialogResult.No)
{
    // ignore it
}
else
{
    // shutdown code goes here
}

There's an MSDN example here.

Answer 2

You need to look at the Form. closing event. You can place your message box there and then if you want to abort the form closing set e.cancel = true.

Answer 3

Have you tried something like:

private void exitToolStripMenuItem_Click(object sender, EventArgs e)
{
   if(MessageBox.Show("Exit Application?", "", MessageBoxButtons.YesNo) == DialogResult.Yes)
   {
      this.Close();
   }
}
