Open the Zip Solution.sln file contained in the VB2017\Chap07\Zip Solution folder file. The btnDisplay_Click procedure should validate the ZIP code entered by the user. To be valid, the first four digits in the ZIP code must be 4210, and the last digit must be 2, 3, or 4. Use one selection structure along with the Like operator to validate the ZIP code. Display the “Valid” message if the ZIP code is valid; otherwise, display the “Not valid” message. After displaying the message, the procedure should send the focus to the txtZip control. Code the procedure. Save the solution and then start and test the application.
