I have a textbox and a button. I'd like to use the button to "save" the textbox.text until it is changed. The textbox.text is an e-mail address or one line. Right now I type the e-mail address into the textbox hit save button and I make the textbox.visible = false and the button.visible = false. The program runs and does what it is suppose to. I shut the program down and next time I run it the textbox is cleared. Is there an easier way to save one line in a textbox without writing to a file and reading back every time the program runs?
