RE: Pre-populating a "file" form field
Hi, Having hashed through the security issues on the list already, I believe that your only option for making this work would be to implement your app as an HTA. This, of course, limits you to support for the IE browser only. Additionally, use of HTA's probably aren't acceptable outside of an Intranet or private application anyway.

RE: Pre-populating a "file" form field
Will, Yes, but look further. in the paragraph below it says: Internet Explorer, Netscape and Opera do not use the VALUE attribute as the default contents of the input area. Any default value set via HTML is not usable via scripting and the DOM as well (hence it is not listed as 'supported' in any of the browsers.) If a user enters text in the field however, that value is then reachable via the DOM as it normally would be for a normal INPUT field (via the .value property.) The reason for this behavior would presumably be to ensure the security/safety of users against malicious authors. --- -Original Message- From: Will Swain [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 02, 2003 10:21 AM To: CF-Talk Subject: RE: Pre-populating a "file" form field but according to this (http://www.blooberry.com/indexdot/html/tagpages/i/inputfile.htm) it does have a value attribute, and also a readonly attribute. will -Original Message- From: Boardwine, David L.

Re: Pre-populating a "file" form field
Mark By any chance do you have clientmanagementenabled on application and is it MX? I cannot get any forms to be repopulated as we are all used to IF clientmanagememt is enabled in MX. Can't do the cf validation routines either: (ThisField_required, thisField_date, etc.) as when user goes back all is lost! If clientmanagement is NOT enabled, it all works as we are used to. E.
