Hello, I am a beginner using Microsoft Visual Basic as my coding program. This exercise is from the "Microsoft Visual Basic 2015 RELOADED 6th edition" book, chapter 11, exercise #15, page 595. This exercise is using an existing code from a different exercise that needs modifications (adding code) according to the exercise's problem.

Here is Exercise #15:

If necessary, complete the eBooks Collection application from this chapters Programming Tut 2, and then close the solution. Use Windows to make a copy of the Ebook Solution folder. Rename the folder Ebook Solution-ModifyThis. Open the solution file contained in the Ebook Solution-ModifyThis folder. The MainForm_ FormClosing procedure should verify that the user wants to save the changes made to the list box. It should then take the appropriate action based on the users response. The removeButton_Click procedure should verify that the user wants to remove the selected eBook from the list box. Use the message Do you want to remove the x eBook?, in which x is the name of the eBook. The procedure should take the appropriate action based on the users response. Modify the code accordingly. Save the solution and then start and test the application. Close the solution. (9, 10)

Here is the code for the "eBooks Collection application", I will do the copying of the folder and rename it Ebook Solution - ModifyThis, sorry I know its a lot of picture uploads, but I wanted to make sure you saw the whole code:

Here is the Interface for Exercise #15:

I am using Visual Basic as my coding program and I am a beginner, I thank you for your work/help in this problem!
