561331 vb.net listboxt to textbox to text file project

Project Description:
Design and develop a Windows application that will read a customer file (sequential) called “customer.txt” when the program starts. It should display Customer ID in a list box. When a user selects a customer ID, it will display customer details in the appropriate textboxes (i.e., customer name, street address, city and state, zip code and telephone number). The program should allow a user to be able to update all parts of customer information (other than customer ID) and save it back to the text file.
