Do you provide a warning before the program exits?

Last updated by Brook Jeynes [SSW] 10 months ago.See history

A product should not close without providing a warning. We use the following message box to warn the user before closing a program:

Figure: Good Example - Standard warning before a program exits

private void OnExit(object sender) 
    EventHandler handler = ExitRequest; 

    if (handler!= null ) 
        handler(sender, EventArgs.Empty);

    string closeTitle = string.Format("Exiting{0}", Application.ProductName);
    string closeMessage = string.Format("Are you sure you want to exit {0}", Application.ProductName);

    DialogResult result = MessageBox.Show(closeMessage, closeTitle, MessageBoxButtons.YesNo, MessageBoxIcon.Warning);

    if (result == DialogResult.Yes)

We have an example of this in the SSW .NET Toolkit.
