Application 'Deactivate' event

I'm looking for something similar with 'Form.Deactivate' event but per application. If I use Form.Deactivate event on my MainForm this event is fired even when I open a modal dialog that has as parent my MainForm.

In conclusion I nedd an event that is fired when my application was deactivated.

It is an odd omission but easily fixed. Paste this in your startup form:

protected void OnActivateApp(bool activate) {
  Console.WriteLine("Activate {0}", activate);
}
protected override void WndProc(ref Message m) {
  // Trap WM_ACTIVATEAPP
  if (m.Msg == 0x1c) OnActivateApp(m.WParam != IntPtr.Zero);
  base.WndProc(ref m);
}
