The following code example shows the SettingsSaving event handler for object of type FormSettings, which is a wrapper class derived from ApplicationSettingsBase. The handler queries the user to save the current application settings property values. The full code example is listed in the ApplicationSettingsBase class overview.

private:
    void FormSettings_SettingsSaving(Object^ sender,
        CancelEventArgs^ e)
    {
        //Should check for settings changes first.
        ::DialogResult^ dialogResult = MessageBox::Show(
            "Save current values for application settings?",
            "Save Settings", MessageBoxButtons::YesNo);
        if (::DialogResult::No == dialogResult)
        {
            e->Cancel = true;
        }
    }

void frmSettings1_SettingsSaving(object sender, CancelEventArgs e)
{
    //Should check for settings changes first.
    DialogResult dr = MessageBox.Show(
                    "Save current values for application settings?",
                    "Save Settings", MessageBoxButtons.YesNo);
    if (DialogResult.No == dr)
    {
        e.Cancel = true;
    }
}

Private Sub frmSettings1_SettingsSaving(ByVal sender As Object, ByVal e As _
        CancelEventArgs) Handles frmSettings1.SettingsSaving
    'Should check for settings changes first.
    Dim dr As DialogResult = MessageBox.Show( _
        "Save current values for application settings?", "Save Settings", _
        MessageBoxButtons.YesNo)
    If (System.Windows.Forms.DialogResult.No = dr) Then
        e.Cancel = True
    End If
End Sub
