>>>A guy here at work wants to have more than one Read Events active at a time. He has a "dashboard" application from which users can run various other applications. Both the dashboard app and the called app have a Read Events. The second one is ignored, which is exactly what the help says will happen. He thinks he saw a workaround in FPA or some other magazine a few years ago. Does anyone know of one?

>>Sometimes we need to set a form up as the base form to a event loop, but we already have established a READ EVENTS statement. Well DOEVENTS to the rescue. Placing a DOEVENTS in a DO WHILE loop simulate the READ EVENTS statement. The _Exit variable controls the final exit of the loop. The last form sets it to .T. when it closes.
