Serialization:
 1. use attribute
  // "[serializable]"
 2. Formatter
  // "BinaryFormatter binaryFormatter = new BinaryFormatter();"
 3.[Noserialized]
 
 //example
 // if the data can generate based some data, then no need to serialize them.
 // overload the OnSerialization() method to do the caculate work
 [Serializable]
 class Products : IDeserializationCallback
 {
  private long statNumber = 1;
  private long endNumber;
  [NonSerialized] private long[] theProducts;
  ...
  public static void Main()
  {
   Products p = new Products(1, 10);
   p.Serialize();
   Products p2 = Products.DeSerialize();
   p2.DisplayProducts();
  }
  public void Serialize()
  {
   FileStream fileStream =
    new FileStream("DoProducts1.out", FileMode.Create);
   binaryFormatter.Serialize(fileStream, this);
   fileStream.Close();
  }
  public static Products DeSerialize()
  {
   FileStream fileStream =
    new FileStream("DoProduct1.out", FileMode.Open);
   BinaryFormatter binaryFormattter =
    new BinaryFormatter();
   Products p = (Products) binaryFormatter.DeSerialize(fileStream);
   fileStream.Close();
   return p;
  }

  pubic virtual void OnDeserialization(object sender)
  {
   //Caculate the none serialized data based on the serialized data
  }
  
  }

Activex Control:
 1. Write in VB or VC
 2. Register Activex Control in dos command windows
  regsvr32 a.ocx
 3. add control to c# project
  // Tool->Customize ToolBox->COM Components->select your component
 4. call
  // label1.Text = axCalculator.Add(ref left, ref right).ToString;
