      {
          //
          // e.Argument always contains whatever was sent to the background worker
          // in RunWorkerAsync. We can simply cast it to its original type.
          //
          GPUZdata argumentTest = e.Argument as GPUZdata;
  
  
  
  
          argumentTest.OneValue = 6;
