Need help on this assignment for visual basic for the assignment the program needs to be aIn this assignment you will complete the Zip application.

The ZIP application validates a five$-$digit

Postal Zip Code entered by the user. The GUI and most of the coding is complete. For the assignment,

you will code the click event handler for the Validate button from pseudo$-$code provided in these

instructions. There is also an opportunity for extra$-$credit. Here you must code the Zip textbox enter

and text changed event handlers. To begin the assignment, download the partially completed Zip

solution folder $($WK$13$ C$7$P Zip Starter.zip$)$ from the Blackboard assignment, unzip the solution folder

and then modify it per the instructions in this document.

Validate Button Click event handler

The btnyalidate 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 $($IF statement$)$ 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 txtziz control, thereby placing the cursor in the

Zip textbox. Begin by creating the btnValidate click event handler, then in the event handler

create the visual basic statements that implement the following pseudo$-$code. NOTE: you

must use only one IF statement and the LIKE operator

$\text{'}$ Trim the leading and trailing spaces from the zip entered by the user

$\text{'}$ if first four characters of the zip are $"4210"$

$,$ and the last character is $2,3$ or $4$ then

$\text{'}$ display "Valid Zip" in the status label $($lblstatus$)$

$\text{'}$ else

$,$ display "Invalid Zip" in the status label $($dblstatus$)$

$\text{'}$ endif

$\text{'}$ Put the focus in the zip textbox $($txatzin$)$

Zip Textbox Enter event $($optional extra credit$)$

Create an Enter event handler for the Zip textbox control. In that event handler, select all the text in

the textbox. A textbox Enter event occurs when the user tabs or back tabs into the Zip textbox.

Zip Textbox TextChanged event $($optional extra credit$)$

Create an TextChanged event handler for the Zip textbox control. In that event handler, clear the Zip

status label. A textbox JextChanged event occurs when the user changes the text in the Zip textbox.

Upon completion of the code changes required by the assignment, you must test the application to

make sure it works properly. Start the application then, at a minimum use the following table of test

cases to test the Zip application.

Create a programming assignment folder per the video in Week $1$ Reading and Course Materials. The

name of your assignment folder should be WK$13$ C$7$P "your last name" In the folder, place the $.$exe file

and an image of the Main Eqrom, vb file $($pdf or $.$jpeg or $.pgg).$ Zip the folder per the video and attach it

to the assignment then submit. ZIP application validates a five$-$digit Postal Zip Code entered by the user
