ThbWaveOut.Active

This property activates and deactivates the waveform-audio output device. Everytime ThbWaveOut.Active is set from False to True, the component begins to play all files and macros the Playlist contains. Playing begins with the first entry and ends with the last one. When playing the last entry has finished, ThbWaveOut.Active is set back False and the ThbWaveOut.OnDone event is fired. Setting Active to False while playing causes playing to stop. No ThbWaveOutOnDone event will be triggerd in that case.
