Where ti disable/intercept the Close Window (X) control ?

In the property windows of the form, there is a "Window Style" allowing me to turn "ControlBox" for Minimize, Maximize and Close controls as well as individual "MaximizeBox" and "MinimizeBox" to True or False.

However, where is the individual control for the Close (X) window ?

My appl users have been accidentally press the (X) control to close the window and I need to intercept this (X) close window control to warn user of this action.

Can someone please tell me how can I either disable/intercept this event ?

I search throught the net and found an answer point to a website for solution no longer exist. If someone can let me know or repost the solution will be appreciated.

in VB2005 you can keep your users from closing your form using this code

VB Code:

Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
        e.Cancel = True
 
    End Sub

Before 2005, it was done with API.
