Example
C#
Java
using Leadtools; 
using Leadtools.Caching; 
using Leadtools.Document; 
 
 
public void DocumentFactoryLoadFromUriAsyncExample() 
{ 
   AutoResetEvent finished = null; 
   EventHandler<LoadAsyncCompletedEventArgs> completed = null; 
   // LoadAsyncProgressEventArgs reference 
   EventHandler<LoadAsyncProgressEventArgs> progress = null; 
 
   completed = (sender, e) => 
   { 
      //Assert((int)e.UserState == 1); 
 
      if (e.Cancelled) 
         Console.WriteLine("Canceled"); 
      if (e.Error != null) 
         Console.WriteLine("Error:" + e.Error.Message); 
      if (e.Document == null) 
         Console.WriteLine("Document is null"); 
 
      var thisOptions = sender as LoadDocumentAsyncOptions; 
      thisOptions.Completed -= completed; 
 
      if (e.Document != null) 
      { 
         PrintOutDocumentInfo(e.Document); 
      } 
 
      finished.Set(); 
      Console.WriteLine("Done"); 
   }; 
 
   progress = (sender, f) => 
   { 
      Console.WriteLine(f.BytesReceived); 
      Console.WriteLine(f.IsCancelPending); 
      Console.WriteLine(f.TotalBytesToReceive); 
 
      var thisOptions = sender as LoadDocumentAsyncOptions; 
      thisOptions.Progress -= progress; 
   }; 
 
   var options = new LoadDocumentAsyncOptions();

   finished = new AutoResetEvent(false); 
   DocumentFactory.LoadFromUriAsync(new Uri("http://localhost/Leadtools.pdf"), options);
