>Did anyone develop code to display a popup alert with VFP? I am looking for something similar to the alerts displayed by Windows Messenger. It would be nice if the pop up can appear while the VFP app is still in the background. TIA.

You might be able to roll one with an invisible form, opened by your app. The invisible form would have a timer to query for for an event. When the event is diacovered, have the invisible form could trigger a property_assign in your VFP app and forward a message?
