As Eduard has said this is usually done from the Form.Closing EventHandler. As an alternative to MessageBoxButtons.YesNo as he suggests, there is MessageBoxButtons.YesNoCancel, and all you then have to do is word the message appropriately.

If you want more ideas, then search the articles here on The Code Project for either notepad or text editor. There are lots of examples, have a look at how they handle this event. In particular look for variables named 'dirty' or 'isDirty' (or something like that) which is how they keep track of whether the text has changed.

Solution 1

Create an event handler for the FormClosing event

The event argument contains a Cancel Property

C#

private void Main_FormClosing(object sender, FormClosingEventArgs e)
{
    if (MessageBox.Show("Are you sure you want to close the application?",
        "Close?", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)
    {
        e.Cancel = true;
    }
}

Now you only have to develop a new form with three buttons, that returns a DialogResult.Yes, DialogResult.No and a DialogResult.Cancel.

Replace the MessageBox.Show in the above code with code that calls your custom window.

Stop using auto-generated method names like "Main_FormClosing"! This is a violation of Microsoft naming conventions. Also, it's the best not to auto-generate any events in Designer. Use anonymous delegates. My 4.

Then, why does Microsoft violate its own naming conventions?

This is the point. Microsoft certainly violates it, also many other rules as reported by FxCop.
I can understand it. Auto-generated code. Who wants to bother while generating code, also, semantic is unknown. It's the developer who is supposed to rename or avoid auto-generation and who knows the semantic. Come to thing about, this violation is handy: find all underscore and than rename semantically. Convenient! From this point, you can immediately tell auto-generated unattended code from the code you paid enough attention to and finalized. Suggest you use this as a tip :-)
