If it is a child form, it opens as a result of a button in a main form:

If MessageBox.Show(" Are you sure you want to exit the application ? ", "Exit  ?", MessageBoxButtons.YesNo) = DialogResult.Yes Then

 Me.Hide() : MainForm.Show()

        Else
            e.Cancel = True
        End If

You can use the following code:

Dim closingfrm = MsgBox(" Are you sure to close", MsgBoxStyle.YesNo)
If closingfrm = DialogResult.Yes Then
Application.Exit()
End If

Copy this:

    Dim result = MessageBox.Show(" Are you sure you want to end the Application", "School Management System", MessageBoxButtons.YesNoCancel)
    If result = DialogResult.Yes Then
        Me.Close()
    End If

If you are using then message box to prevent accidental form close, your approach may not work always. The message box will not be shown if the user closes the application in any other way than clicking the "Close" button.

Try using the FormClosing event.

'Close Button
Private Sub BtnClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnClose.Click
    Me.Close()
End Sub

'FormClosing Event
Private Sub MyForm_Closing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
    If MessageBox.Show(" Are you sure you want to quit", "Are you sure?", MessageBoxButtons.YesNoCancel) <> DialogResult.Yes
         e.Cancel = True
    End If
End Sub

Private Sub btnClose_Click(sender As Object, e As EventArgs) Handles btnClose.Click
  If MsgBox("Are you sure you want to quit?", MsgBoxStyle.YesNo Or MsgBoxStyle.DefaultButton2, "Close application") = Windows.Forms.DialogResult.Yes Then
    Me.Close()
  End If
End Sub

You are doing nothing with the value of result. You need to inspect the value and determine whether you call Me.Close(). Code approximately

If result = DialogResult.Yes Then
    Me.Close()
End If

You issue Me.Close() no matter what the result is. Check the result and execute Me.Close() only the user clicks Yes
