Interrupting StockAudioPlayer1.PlayStock with new item

Postby Amadeus » August 20th, 2007, 11:19 pm

How can I interrupt playing a file, before it has finished, without getting a "Device is already[spelling mistake here] open" error, allowing further sounds to be played in rapid succession.

A Stop method would do the trick I imagine, but is not available.

Set Active property to False.

This was the first thing I tried but setting the Active state to false alone does not seem to close the instance of the Player.

Code: Select all
procedure TForm1.Button1Click(Sender: TObject);
begin
  StockAudioPlayer1.Active := false;
  StockAudioPlayer1.PlayStock(0);
end;


Clicking the button before the file is played still creates an error.

When Async property is True, you may need to use WaitForStop method or Sleep API to wait until callback thread stops.

Code: Select all
procedure TForm1.Button1Click(Sender: TObject);
begin
  StockAudioPlayer1.Active := false;

  StockAudioPlayer1.WaitForStop;
  // OR
  Sleep(10);

  StockAudioPlayer1.PlayStock(0);
end;

That does it, the explanation is under the class methods and I didn't look beyond the component properties definitions. My mistake.

Thanks for that and thanks for creating a substitute to the TabcWaveList.
