retrieve a string from the textbox of this dialog  other than create an instance 
of InputDialog,at the mean time I want to customize the caption text and the 
prompt message of the InputDialog in the static method InputDialog.getString.But 
I can't modify Form.text, (form.)TextBox.text  in the static method.Currently I 
have to  use its non-static version of getString method and create an instance 
of the dialog each time when I call getString.

since non-static data is only created with an instance you would have to use 
some sort of Singleton or something, I suppose.
