private:
   void MakeLabelVisible()
   {
      
      /* If the panel contains label1, bring it
         * to the front to make sure it is visible. */
      if ( panel1->Contains( label1 ) )
      {
         label1->BringToFront();
      }
   }

private void MakeLabelVisible()
{
   /* If the panel contains label1, bring it 
   * to the front to make sure it is visible. */
   if(panel1.Contains(label1))
   {
      label1.BringToFront();
   }
}

Private Sub MakeLabelVisible()
   ' If the panel contains label1, bring it 
   ' to the front to make sure it is visible. 
   If panel1.Contains(label1) Then

   End If
