' define message exit."     style = msgboxstyle.defaultbutton2 or _         msgboxstyle.question or msgboxstyle.yesno     title = "exit"     ' display message.     response = msgbox(msg, style, title)     if response = msgboxresult.no         if label7.text = "l  o   d   n  g"             button1.enabled = true             button5.enabled = false             textbox1.enabled = true         end if     end if     if response = msgboxresult.yes         me.close()     end if
