using Leadtools.WinForms; 
using Leadtools.Drawing; 
 
public void AnnAutomation_PlayAudio(AnnAutomation automation, string audioFilename) 
{ 
   // make sure no objects are selected 
   automation.SelectNone(); 
 
   // see if we can play audio (should say no) 
   if (!automation.CanPlayAudio) 
      MessageBox.Show("Cannot play audio"); 
 
   // add an audio object and select it 
   AnnAudioObject audio = new AnnAudioObject(); 
   audio.Bounds = new AnnRectangle(100, 100, 200, 200, AnnUnit.Pixel); 
   automation.Container.Objects.Add(audio); 
   automation.StartEditing(audio, false); 
 
   // see if we can play audio  
   // (should say no, since the audio object does not have an audio file in the filename yet) 
   if (!automation.CanPlayAudio) 
      MessageBox.Show("Cannot play audio"); 
 
   // set up the filename for this audio object 
   audio.FileName = audioFilename; 
 
   // see if we can play audio (should play it now) 
   if (automation.CanPlayAudio) 
      automation.PlayAudio(); 
}
