It's not possible. You can warn them it's required (that will happen automatically via the yellow Document Message Bar) but all the functions to close a file rely on JavaScript.

The strategy in such a situation is the other way around. You allow opening the document, but in a way that it is unusable. Then you use JavaScript to make it usable (such as showing contents). So, if your user has JavaScript deactivated or uses a viewer which does not support JavaScript, can not use the document. It is, of course, helpful to let the user know why the document can not be used.HTH.

maxwyss, what would be the best (less expensive, easier,quicker) way to go about placing this form control in the pdf - using XFA or Livecycle designed? will the form control have to be placed on each page or can i just place one form control at the pdf level that dosent scroll with the pages but disappears once the user logs in correctly? appreciate the asistance. thanks

The inserting and hiding of the form field is very much dependent upon how the form was created.
XFA is the format used by LiveCycle Designer.
With a multiple page form you could to place a the warning form field on all pages and use a form JavaScript object to hide the fields.
If you created the form using Acrobat, you put the warning field with the same field name on all pages and use a document level script to hide that field. It would even be possible to perform this task as an Action in Acrobat X or a batch process in older versions.

could there be just one form field that covers all the pages that gets disabled by a document level javascript when the user enters a user id/pwd that is authenitcated against a web-service? could there be any other technical hurdles to this approach, since im bit of a novice?
thx
