Here is the code template for a form's FormClosing event handler:

Private Sub MainForm$\_$FormClosing$($sender As Object,

e As System. Windows, Forms, FormClosingEventArgs$)$

Handles Me$.$ FormClosing

End Sub

Suppose you want the form to close only if the user knows the secret word, which is water. Write statements in this procedure to ask the user to enter the secret word. If the user enters the correct secret word, the form should close. Otherwise, the form should not close. $($Perform a caseinsensitive test for the secret word.$)$
