How do I add code to the exit button in a c# form?

Question

I'm using Microsoft Visual C# 2008 Express.

In my main form, there's that X button to close the form at the top right. How do I add code to this button? In my menu, I have an "Exit" item and it has code that cleans up and closes my databases. How do I add the same code to this button if the user chooses that as a way to exit?

Thanks!

Answer 1

Using the FormClosing Event should catch any way of closing the form.

Answer 2

In the Design view for your form, within the Properties window, select the Events button and scroll down to the "FormClosed" and "FormClosing" events.

FormClosed is called after the form is closed.

FormClosing is called before the form is closed and also allows you to cancel the close, keeping the form open:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    e.Cancel = true;
}
