No. If you set it to ‘inline’ then when the user submits the form a link will appear on the page and he must click the link to view the file in the browser, or you can try to force it to download at that point, rather than display in-browser .. this is the difference, for example, between seeing a PDF file [if that was your download file] appear in the browser or instead getting the little file-save popup window that lets you save it as a file locally and doesn’t display in the browser). So, no, you cannot get around the part where the user has to click the link first (after submitting the form).
That said, if you set it to ’email’ rather than ‘inline’, then when the user submits the form an email will be kicked out to him rather than a link being displayed on the page. If you turn on attachments, then the email will have the file attached (rather than a link he has to click to download the file). So, that’s not what you’re looking for, but it is an alternative way that some people like — I use this on some of my sites because I know for sure that the user isn’t getting a file unless he gives me a good email address. Otherwise, he might just put some random stuff into the email address field.
Anyway, the answer to your question is no. Sorry.
