PhoneNumberValidator

Project is to be made in Visual [login to view URL] *User interface is included for the project* Design and develop a program that validates the value a user enters into a TextBox control to ensure that the entry is a valid telephone number. The application should accept a maximum of 12 characters. When the user clicks a button, the program should determine if the entry is of the form 999-999-9999, where the character 9 represents any number. If the entry is determined to be a telephone number, display an appropriate message, along with the separate substrings that compose the telephone number without the dashes. If the entry is not a telephone number, then display a message as to the reason why the entry is not a valid telephone number, clear the TextBox control and set focus to the TextBox control. Use String class methods to solve the problem. Here are a few hints to help you code the String methods: 1. Check that the user has entered two dashes in the appropriate spaces. 2. Break the string into 3 substrings, represented as 999,999, and 9999. Use the Visual Basic .NET IsNumeric() function to determine whether each substring is a valid number. The function accepts one parameter and returns a True or False value. • New key ideas of this assignment include: o String variables o Substring and Length() methods. o MsgBox() o Focus():  syntax: [login to view URL]() , where control is the name of a control that will receive focus during run time.  Example: [login to view URL]() The cmbCreditRating control receives focus when the above statement is executed o IsNumeric() as explained in the assignment o IsNumeric does not filter dash "-", comma "," or decimal point "." characters so your program must use IndexOf to filter for these characters in your substrings Must use if then else statements.... ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
