Create a simple text editor that has one large text box (with its Multiline property set to True) or a RichTextBox control. Set the text control to fill the form and set its Anchor property to all four edges, so that the control fills the form even when it is resized.
Allow the user to save the contents of the text box in a data file and load a data file into the text box using the Open File dialog box. Use a StreamWriter and StreamReader or My. Computer. FileSystem. WriteAllText and My.Computer.FileSystem.ReadAllText.
Hint: You will need to save multiple lines.
