The test is open book, open notes, open projects, etc.  However, you may not ask for help from other people either in the class or out of the class.  Do your best work.  If you don't fully understand a problem or question do as much as you can.  Partial credit will be given.  Please limit your answers to the space provided.

This test is due before 7:45pm on Wednesday, April 22, 2009.  Late tests cannot be accepted.

For each programming question you answer please zip up your complete project folder including all source code, project, and solution files.  Then, rename the zip file to: FinalW2008-Q1.zip where Q1 is for question 1, FinalW2008-Q2.zip where Q2 is for question 2, and so forth.  Finally, place the zipped file for each question you answer in your folder on the FTP site.  The date/time of the zip file will be used to determine when you handed it in.

I will use the same grading procedures I have used on previous programs (this includes looking at properly named classes, variables, and files; as well as checking for comments in your code).

Please answer the following 2 questions (100 points each):

Question 1
Write a program that will use the “Form.Paint” event and a timer to draw shapes that will “bounce” around the client area of the form.  This program will have three menu items: “About…”, “Add Shape”, and “Exit”.  The “About…” menu item will display a standard about dialog with your name on it.  The “Exit” menu item will terminate the program.  The “Add Shape” menu item will increase the number of bouncing shapes by one.

When the program starts, there should be no shapes “bouncing” in the window.  Each time the “Add Shape” menu item is selected, a new shape should start “bouncing.”  Each new shape should start with a random position, direction, and speed.

A shape “bounces” by moving through the window client area with a particular direction and speed.  When it reaches the edge of the window, its direction should reverse, thus “bouncing” off the edge.  Make sure each shape’s direction has both vertical and horizontal components (i.e. it can move diagonally).  You should use the Graphics class to draw your shape.  The shape you choose can be anything you wish, as long as you use methods of the Graphics class to draw it.  DO NOT use a picture box.

Aside from the requirements to use the Paint event, a timer, and the Graphics class, you may use any other programming tool/construct we have discussed in this class to accomplish this.

EXTRA CREDIT (5 Points): Each time you add a shape to the window, randomly select one of three shapes to “bounce.”

Question 2
Write a program that has three controls on one main form: a single line text box next to a button labeled “Search”, and a RichTextBox that will occupy the majority of the form.  This program will also have a menu with four items on it: “Load File”, “Save File”, “About…”, and “Exit”.  This program will read a text file from disk and display the file in a RichTextBox control.  It should also be able to write out any modified text to a file as well.  (You may have to use the help files to learn about the features of the RichTextBox control).  The user should also be able to enter a regular expression in the text box and show the results of the search in the RichTextBox when the “Search” button is pressed.

The “Load File” menu item will be used to display the OpenFileDialog to request a file to load into the RichTextBox, the “Save File” menu item will be used to display the SaveFileDialog to request a file to save any modified text to, the “About…” menu item will display a standard about dialog, and the “Exit” menu item will terminate the program.

When the user enters a regular expression in the text box and clicks the “Search” button, you should perform a search using a Regex object.  You should then display ALL the results by first clearing any previous searches, and then highlighting all the matches in the RichTextBox.  Text can be highlighted or cleared by using the following methods of a RichTextBox: first, select the text using the Select() or SelectAll() methods, second change the text color/background using the SelectionColor and SelectionBackColor properties, and finally, clearing the selection by using the Select() method again.  You must research how to properly specify parameters and values for these properties and methods.
