COP4226, Homework 3

Due Wednesday, November 14 (late 6am 11/15)

Zip your entire project and upload on the web. Exclude the Debug and Release directories.
Submitting Homework Online.

Be sure to include your control library in your uploaded file.

Create a Single Instance, Single Document Interface application.

Avoid long methods. Each method that you create should be short, to promote encapsulation. If you have a method that is longer than 25 lines, then it probably needs to be divided into smaller methods.

Do not create a new data structure if one that already exists will solve the problem.

Extra Credit (due 11/11)

If you submit the sections below that have the same style as this paragraph, then you can earn an extra 2.5 points of extra credit towards the course grade.

Single Instance Application

• Create a single instance application.
• Use an application context that displays a message box every two minutes that the application is running. The message box should indicate the total time that the application has been running.
• Add a status bar that indicates the state of the insert key.
• Allow drag and drop of text. Allow copy of text from the clipboard. In both cases, split the text into words. Add the new text to the document. If the insert key is off, then clear the document of words first.
• Allow serialization and deserialization of the document.
  • Use a SaveFileDialog for serailizing. Add a default extension of your choice.
  • Use an OpenFileDialog for deseraializing. Show only files with your extension. Allow for another option to display all files.
• Allow printing and print preview of the document.
  • Print the information for each word that is in the document: text, location, font.
  • Print the information in columns.
  • Fill each page with the maximum number of lines that will fit within the actual margin bounds. Each line will contain the above information. Tabs will be helpful.
  • Print a header on each page that contains the course aligned to the left and the name of the assignment aligned to the right. The header should be outside the actual margin bounds and within the actual page bounds.
  • Print a footer on each page that contains your name centered and the page number aligned to the right. The footer should be outside the actual margin bounds and within the actual page bounds.
  • Use different fonts for the header, footer and content of the page. Use a serif font, a sans serif font and a monospace font. For one of them, use a generic font family. Make the header font bold; make the footer font italic.
  • When printing is chosen, open a print dialog. Allow the user to print selections and ranges.
• Create two views for the application.
  • Paint view. Display all words so that they fit within the client area and do not overlap each other. Add a vertical scroll bar, if necessary. Display each word at its location, using its font. Changes to the document should reflect in this view.
  • Word grid. Display all the words in a grid view.
    • Do not allow the text to be changed.
    • Allow all other properties to be changed.
    • Changes to the grid view should change the underlying document.
    • Changes to the document should reflect in this view.
    • Use data binding.
    • Allow new words to be added. Text should be modifiable when adding a new row.
    • You do not have to validate new data. Just be sure to enter valid data.
• Be able to right click any word in the Paint View and open a dialog that can change the text, location and font.
  • Only allow one word for the text.
  • Use data binding.
  • Add next and previous buttons that will navigate through the words in the document.
  • Be able to move the dialog by using the arrow keys. Maintain the default handling of the arrow keys, too.
• When a new instance of the application is started, add each command line argument to the document. If the insert key is off, then clear the document first.
• Add Oath and About dialogs to the application.
• Add appropriate menu items for all the functions in the assignment.
• Add a toolbar for print, print preview, paste from clipboard, search. Search should only be visible when the Paint View is active. It should appear directly below the main menu for the application. You may need to change the docking order in order to make it appear correctly.
• Use a tab control for the two views.
• Use your control library as in other assignments.
