   cap = New TwainCapability()
   cap.Information.ContainerType = Leadtools.Twain.TwainContainerType.OneValue
   cap.Information.Type = Leadtools.Twain.TwainCapabilityType.ImageTransferMechanism
   cap.OneValueCapability.ItemType = Leadtools.Twain.TwainItemType.Uint16

   cap.OneValueCapability.Value = Leadtools.Twain.TwainCapabilityValue.TransferMechanismNative

   cap.OneValueCapability.ItemType = Leadtools.Twain.TwainItemType.Uint16; 
 
   cap.OneValueCapability.Value = Leadtools.Twain.TwainCapabilityValue.TransferMechanismNative; 
 
   session.SetCapability(cap, TwainSetCapabilityMode.Set); 
   session.SaveTemplateFile(LeadtoolsExamples.Common.ImagesPath.Path + "test.ltt"); 
   session.Shutdown();
