here is my code, it is very simple

        MsgBox("Update successful!", MsgBoxStyle.OkOnly, "")

Actually, I have been programming for a year or two three years ago but I stopped after my laptop was stolen and due to work.
But now I I have a new laptop, and upgraded from vb 2008 to 2013. I have been through all these kind of errors before and it is so surprising that I can no longer solve them. Please please help
