How do you Cancel a Form Unload Progress in vb6?

In VB6, you can cancel a Form Unload event by setting the Cancel parameter of the Form_Unload event to True. To do this, you need to declare the Unload event with a parameter, like this:

<code class="language-vb">Private Sub Form_Unload(Cancel As Integer)
If MsgBox("Do you really want to close the form?", vbYesNo) = vbNo Then Cancel = True End If End Sub
</code>

This will prompt the user, and if they select "No," the form will remain open.
