Re: [oopic] New to OOPIC Event Programming..pls help..

The oEvent object only triggers on a low-to-high transition, so toggle
isn't what I would use for the button. Try one that just acts like a
momentary contact. When you trigger the event you turn on the sound,
but you never turn it off, that isn't likely to do anything useful
either, you should just "blip" it in the event handler. Another idea is
to set e.Operate = 0 initially to make sure of its initial state.
