View 1 RepliesI have to make a basic program that: Create a program with a simple interface that
1. Asks the user type his/her email address into a textbox.
2. When the user clicks the "Evaluate Email Address" button, one of two message boxes pops up: "That is a valid email address!" with an "Information" icon, or "That is an invalid email address!" and on a second line, "Please retype your email address.", with an "Exclamation" icon
3. To be considered valid, the email address must -include an "@" symbol, and -it must end in either ".com", ".net", or ".org" or ".edu" (I don't know how to check a string and test if its last four characters end with any of these and make it say not valid email address. I think I might have to use a case statement)
