Summary
This article provides a workaround using workflow to prevent users from downloading a local copy of attachment.
Question
In workflow , the Functions for manipulating attachments "Attachment_New" , "Attachment_CanDelete" and "Attachment_CanOpen" will not help to prevent users from downloading the attachment locally to a computer.Users can save a local copy of attachment by clicking on 'Save As" button.
Is there a way to prevent users from downloading a local copy of attachment using workflow ?
Answer
NOTE : Script provided here is only on an "AS-IS" basis. Workflow customization is out of scope of support .
Workflow code can be used to disable the action of the “Save As” button.
The code must be implemented in "ActionCanExecute" subroutine after the following line:
ActionCanExecute = DefaultRes
Here is the example code which checks whether the button was clicked and disables its action:
============
if (actionname = "Attachment.Save" or actionname = "attach__download_save") then
ActionCanExecute = false
end if
===========
Users need to include this logic in their workflow and enhance it as per the need. The script is just a example and not a complete solution.
