Restrict direct input of filename in inputbox,
October 28, 2008 at 4:14 PM

Can anyone tell me how to restrict the user from directly entering the filename into the input box? If the input is not a name of an existing file (e.g. due to a typo), then the form will be sent as if an empty file had been specified (though with the name given by the user), and no warning is given.
