Odd and Even Number Checker in Visual Basic NET

Here is a simple program that I wrote using Microsoft Visual Studio 2012 and my language is Visual Basic NET to check if the given number of the user is an odd or even number using the operator MOD. I also include error detection if text field is empty and then the user click the ok button our program will display a message informing the user that the text field needs a value.
