title: uninstall dialogs
body: <p>I am composing a setup project in VS2010 . I want to add a dialog with checkbox for the user to specify if he wants to delete the database or not. But I can't figure out how to do it: the user interface doesn't represent the uninstall dialogs on the "view dialogs" form. So I can show a messagebox instead, but then there is another problem: how can a person specify whether the database should be deleted or not if the uninstaller is launched in a quited mode? In that case some parameters should be passed to the setup project somehow. Got any thoughts?</p>
