A good example would be a web server implementing Keep-Alive. You may need to prevent new inbound connections, possibly for load balancing or other resource allocation requirements, but preserve the internal state data.

Dont forget that just because you've never needed to do it doesn't mean no-one ever needs to do it.

And you are suggesting that you would not do that when stopping as well?

1) Create a totally new variable, unconnected to any previous versions.

2) Access the correct old version of the variable that you had kicking around somewhere else in your program, but not to worry, the compiler will sort out which one your mean to use when it gets to it.

   {
   Form2 rhbForm = new Form2();

   txtGsm1.Text = rhbForm.txtGsm1.Text;
   txtGsm2.Text = rhbForm.txtGsm2.Text;
   txtNumara.Text = rhbForm.txtNumara.Text;
   }

public class Form2 : Form
   {
   ...
   public string Gsm1
      {
      get { return txtGsm1.Text; }

   ...
   }

    // It's good practice to Dispose of forms. By wrapping
