The inputBox's third positional argument is the initial text in its textbox. The default value for this argument is "". In my application, I use an inputBox to ask a user to specify the name for a new record when he clicks an "Add Record" button. If he presses "cancel", no problem: seems he changed his mind about that new record. I exit the sub. However, if

问题 A little background: I am working on a sliding block puzzle for a school project and this is our first using C++ instead of Java.
