Form_Closing event .

Like this

VB Code:

Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles 
MyBase.Closing
 
If MessageBox.Show("Close this form ?", Nothing, MessageBoxButtons.YesNo) = DialogResult.Yes Then
            e.Cancel = False
        Else
            e.Cancel = True
        End If
 
 End Sub
