Unit VII Project

For this project, create a new application and apply what you learned in this unit to your application. Be sure to perform

the following:

1. Include a text box and prevent the entry of unwanted characters in a text box.

2. Create a message box with the MessageBox.Show method.

3. Include the Trim method and remove any leading and/or trailing spaces from a string.

Test your application by using valid and invalid data to ensure that your application provides the correct results. Refer to

the testing guidelines in Figure11-1 on page 238. Save your application (in Visual Basic), save the file after applying any edits. Submit the GUI (i.e., the Visual Basic file) in Blackboard for grading.
