Activating a form brings it to the front if this is the active application, or it flashes the window caption if this is not the active application. If the forms contain no visible, enabled controls, the LostFocus event occurs for the first form before the Deactivate event, and the GotFocus event occurs for the second form after the Activate event.

You can use the ShowToolbar action in an Activate or Deactivate macro to display or hide a custom toolbar.

You could then create a base class inheriting from Form , handle the Load event to add the current form to the list of forms and the Closed event to remove it. Once you have that class, have all your real forms derive from it. BTW, it's almost how it is done in. Net 2. Turn the problem around and have the working thread raise events when the values change that you can handle in each form to update it.
