Public Event SettingsSaving As SettingsSavingEventHandler
Dim instance As ApplicationSettingsBase
Dim handler As SettingsSavingEventHandler

public event SettingsSavingEventHandler SettingsSaving

event SettingsSavingEventHandler^ SettingsSaving {
void add (SettingsSavingEventHandler^ value);
void remove (SettingsSavingEventHandler^ value);

JScript does not support events.
The SettingsSaving event is raised by the Save method before it stores the application settings properties to their associated data store. The associated event handler can cancel this event.
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 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
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:
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;
}
