I didn't realise you could manage the lenght during a tostring() operation.

public class Form1
{
  public string ClientID
  {
    get{ return ClientID.Text; }
    set{ ClientID.Text = value; }
  }
}

public class Form2
{
  public Form2(Form frm)
  {
     string id = frm.ClientID;
  }
}

int ClientID;
        int ProductID;

        public Form2(int clientID, int productID)
        {
            this.ClientID = clientID;
            this.ProductID = productID;
        }

        private void Form1_Load(object sender, EventArgs e)

            //use ClientID and ProductID here.

As long as I can generate a string of digits that are fixed in length, and different everytime I generate a new serial number, then this method would be fine.
