Write an XML code that displays the user interface illustrated in the above figure

Create an application class named LetterDemo that instantiates objects of two classes named Letter and CertifiedLetter and that demonstrates all their methods. The classes are used by a company to keep track of letters they mail to clients. The Letter class includes auto-implemented properties for the name of the recipient and the date mailed. Also, include a ToString() method that overrides the Object classs ToString() method and returns a string that contains the name of the class (using CetType and the Letters data field values. Create a child class named CertifiedLetter that includes an auto-implemented property that holds a tracking number for the letter.

Create an application that calculates and displays two raise amounts, which are based on an employee’s current salary. The current salary will be entered by the user. The two raise rates are 5% and 8%. In addition to the raise amounts, the application should also calculate and display the employee’s new salaries. Include a button in the interface that the user can click to clear the user input and calculated results from the screen. Prepare a Planning Chart for the application. Draw a sketch of an appropriate interface. Be sure to follow the GUI design guidelines covered in the chapter. The guidelines are summarized in Figure 2-20. (If you want to include an image in the interface, you can either use your own image file or download an image file from openclipart.org. When downloading from openclipart.org, be sure to use the SMALL IMAGE (.PNG) button.) Create a Windows Forms application. Use the following names for the project and solution, respectively: Salary Project and Salary Solution. Save the application in the VB2017\Chap02 folder. Use your Planning Chart as a guide when building the interface. Code the Exit button. (You do not need to code the button that calculates and displays the raises and new salaries or the button that clears the user input and calculated results.) Save the solution and then start the application. Test the access keys, tab order, and Exit button and then close the solution.
