Is this a web application or a desktop application. If its a web app, is your desired interface absolutely required? Most web mail apps use multiple htmlInputFile controls for multiple files. The following links may help you:

If this is a desktop application, you should be able to use an open file dialog to select multiple files and then populate your list programmatically. See this link for info on the open file dialog: http://www.startvbdotnet.com/controls/dialog.aspx.
