How to call a button from a message box (made using a form) in another form?

[Siobhan Shum]

Dear all,

I am trying to program a dialogue box to appear when the exit button from my 'Login' form is clicked.
The form has three options; yes, no, cancel.

The code so far:

' Cancel button   
    Private Sub Cancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox4.Click
        Dim mainForm As New DBexit
        DBexit.Show()
        If yes.click = True Then

        End If
    End Sub

The dialogue box is the form called 'DBexit'
It shows the dialogue box but I am not sure how to proceed to code the buttons from another form into the 'Login' form as the buttons 'yes', 'no' and 'cancel' have not been declared.

Thank you for your time and help.

Try this

Dim mainform As New DBexit
        Select Case mainform.ShowDialog
            Case Is = Windows.Forms.DialogResult.Yes
                ' do yes option
            Case Is = Windows.Forms.DialogResult.No
                'do no option
            Case Is = Windows.Forms.DialogResult.Cancel
                ' do cancel option
            Case Else
                ' do oops options
        End Select

Then in dbexit in each button click event set the dialog result

Private Sub btYes_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btYes.Click
        DialogResult = Windows.Forms.DialogResult.Yes
        Me.Close()
    End Sub
