Modify from MenuDialog to create a simple text editor. You
need to add [STAThread]
Before its Main method to make it work.
In File menu, add option like New, Open, Save, Save As,Close,
and Exit.
When the user selects Save As, display a SaveFileDialog to let
the user to select a filename and whatever in the textbox should
be saved to this file.

6. When the user selects Save, display a SaveFileDialog if the file
has not been opened (created after the user clicked New or
Close).
Both objects from OpenFileDialog and SaveFileDialog has a
property called FileName. Define an instance variable of String
type called filename to hold file name after an OpenFileDialog
or SaveFileDialog is created. When the user clicks Save and
filename is null, display SaveFileDialog.
When New and Close is selected, simply set textbox as empty
string like textBox1.Text=”” and set filename as null.
Add a menu called Edit with three items like Cut, Copy, Paste
textBox1.selectedText returns the selected text from the textbox
Clipboard.SetText(textBox1.SelectedText) adds selectedText to
Clipboard
Clipboard.GetText() returns what is in the clipboard.
When the user clicks cut or copy, set the clipboard with the text
selected
When paste is clicked, set textBox1.Text as
textBox1.Text.Substring(0, textBox1.SelectionStart) + what is
in the clipboard +
textBox1.Text.Substring(textBox1.SelectionStart +
textBox1.SelectionLength);
When cut is clicked, it is almost same as above except “what is
in the clipboard” will be empty string
Add another menu like Help with one or two option like who
created the editor and version etc.
Add one line like: text.Dock = DockStyle.Fill;to make the

7. textarea stretch to the whole window

13. LIT331/332 Brief Writing Assignments Overview and Standards
You will be required to submit a brief writing assignment each
week during Seminars One through Five. The writing topic will
be provided during that seminar.
Note that you should be taking notes as the seminar progresses
so that by the end you’ve got a rather clear path toward the
writing assignment.
Basic standards:
· APA formatting (title page, double-spaced, citations).
· Thesis statement should reflect the writing prompt.
· Organize these as basic essays—set up your point in an
introduction paragraph, give three supporting points that rely on
the readings for examples, and conclude with a clear summation
of your larger argument/response to the question.
· Supporting details are required from the readings. Note that
since these are relatively short assignments, you don’t want to
waste a lot of time summarizing the texts—assume your
audience has read them and get to the point quickly. Quotations
should be used as support, rather than content.
· The final length should be approximately 1 ½ - 2 pages (350-
500 words).
· Standard English is required.
· No first person.
