Validation

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.

2. Check that the user has entered two dashes in the appropriate spaces.

3. 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.

Make sure the code is written as simple as possible Nothing out of the ordinary.
