How do I stop the form from closing / How do I prompt the user to confirm the closing of the application when he presses the X button?

There are a few reasons why you may want this, in some applications, for example, you may want to ask the user if he wants to save the work before closing. You can easily do this by handling the form’s Closing event.
In the following example we stop a form named Form1 from closing when clicking the ‘X’ shaped button:

private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
e.Cancel = true;
}

In the following example we prompt the user to confirm the closing of the application:

private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
if(MessageBox.Show(“Are you sure you want to exit?”, “Confirm exit”, MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)
{
e.Cancel = true;
}
}
