• You will create a program that will read a text file and perform various text processing procedures.  Your main form should consist mainly of a menu and a text box.  You will place a few other controls on the form for statistics display and user input (as described below), but the majority of the form should consist of the text box.
• Create a menu that has five commands: "Open", "Save", "Close", "Exit", and "About"
• "Open" - Will ask the user to select a text file (with the open file dialog), will read in that text file, storing it in a string, and display it in a text box on the form.  It will also clear any previous statistics that are displayed.
• "Save" - Will prompt the user for a file name that will save the text in the text box out to a new file.  Don't allow the user to save over the top of any previously loaded file.
• "Close" - Will erase the text out of the text box and clear any previous statistics that are displayed.
• "Exit" - Will exit the program.
• "About" - Will display an about box with your name and project title (as in previous projects).
• The "Save" and "Close" menu items should be grayed out appropriately, i.e., if no file is open, they should be grayed.  Also, if a file has been opened, but not modified, then the "Save" menu should be grayed as well.
• You should also have a button on your form called "Calculate" that when pressed will calculate statistics on the text in the text box.  It should also be grayed appropriately when there is no file opened.
• When the "Calculate button is pressed, you should perform a number of searches.  Find the number of times the words "And" "Of" and "The" are in the document (ignoring case).  Find the number of sentences in the document.  Find the number of words in the document.  Display the results as you wish on the surface of the form.
• Also, you should have another small text box with a corresponding buttons labeled "Search", "Next".  This will allow the user to enter a regular expression and search for it in the text in the text box.  When "Search" is clicked, you should search for the regular expression.  If no matches are found, you should display a message box stating so.  If any matches are found, show in a label control the number of matches found, and highlight the first match in the text box.
• When the "Next" button is clicked, highlight the next match and so forth until all matches have been displayed.  At which point display a message box saying there are no more matches.
• The text I will use to test your code can be found here.
