Exercise 9-2 Work with strings In this exercise, youll add code that parses an email address and formats the city, state, and zip code portion of an address. Open the project and add code to parse an email address

1. Open the StringHandling project in the Assignment Exercises\Chapter 09\StringHandling directory.

2. Add code to parse the email address into two parts when the user clicks the Parse button: the user name before the @ sign and the domain name after the @ sign. Be sure to check that the email contains an @ sign before you parse it, and display an error message if it doesnt. Also, be sure to remove any leading or trailing spaces that the user enters. Display the results in a message box like the first one shown above.

3. Test the application with both valid and invalid email addresses to be sure it works correctly. Add code to format an address

4. Add code to format the city, state, and zip code when the user clicks the Format button. To do that, create a string that contains the city, state, and zip code and then use the Insert method to insert the appropriate characters. Be sure that the two-character state code is in uppercase. (You can assume that the user enters appropriate data in each text box.) Display the results in a message box like the second one shown above.

5. Test the application to be sure it formats the city, state, and zip code correctly.

Here is the starting code:

Public Class Form1

Private Sub btnExit_Click(sender As Object, e As EventArgs) Handles btnExit.Click Me.Close() End Sub

Private Sub btnFormat_Click(sender As Object, e As EventArgs) Handles btnFormat.Click End Sub

Private Sub btnParse_Click(sender As Object, e As EventArgs) Handles btnParse.Click

End Sub End Class
