Using RadioButtons in a GroupBox; String methods, including .ToUpper, .ToLower, .Length, .IndexOf(), .Substring(). Also IsNumeric()
Shell program located at http://bowerpower.net/compprog1/vb04/StringMethodsAndRadioButtons.zip How could you use an IF block to address a program that crashes when it searches for a subtring that is longer than the original string (try using a three-letter word in the program we created - it should crash)?
