Project $2-2$ Maintain student scores

For this project, you'll develop an app that lets the user add students to a list, change the scores for a student in the list, and delete a student from the list. Prerequisites: chapters $1-10.$

$-$ To update an existing student's scores, the user selects the student in the list box and clicks the Update button to display the Update Student Scores dialog.

$-$ To remove all scores from the Scores list box, the user clicks the Clear Scores button.

$-$ To accept all changes, the user clicks the OK button.

$-$ To cancel the update operation, the user clicks the Cancel button.

Specifications

$-$ This app should make sure that the user enters a name for a new student. However, a new student can be added without any scores.

$-$ This app should check all scores entered by the user to make sure that each score is a valid integer from $0$ to $100.$

$-$ When the app starts, it should load the list box with three sample students.

Hint

$-$ To get the labels that display the score total, score count, and average on the Student Scores form, the scores on the Add New Student form, and the name on the Update Student Scores form to look like the ones shown above, you'll need to set the AutoSize property of the labels to False and the BorderStyle property to Fixed$3$D$.$
