building app

I have to 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. I an supposed to use the Visual Basic .NET IsNumeric() function to determine whether each substring is a valid number. I need the user interface and code to run the program. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Exclusive and complete copyrights to all work purchased.
