create image of application and store to database <p>I have create a application in c#. What my problem was when user try to edit something new to database via this application, it will not save to main table in database directly, but will store on another table, and waiting for another user to approve it.</p> <p>In this case, if user try to edit, I wish to save the application image and store to the table, and when another user come and approve it, it can show different before edit and after edit, this is much convenience for user to view and make decision.</p> <p>I have search through internet, but I can not find a good solution to solve this problem, anyone can help please.</p>
