Thank you everyone who replied to my problem. I have decided now to go with Anna's solution and so far it's working great! So thank you very much for your help Anna.
Thanks again, Andy. -----Original Message----- From: anna w [mailto:[EMAIL PROTECTED] Sent: Wednesday, 01 December 2004 11:17 To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: Multi-User Update Problem Hi Andy Users will always leave browsers open with 'locked' records & go home/to a meeting/ power down, so don't prevent access to locked records. In fact don't lock them unless you really have to. Maybe this would suit you better... Add a timestamp to the relevant tables. Add it to the primary key index. Always retrieve the timestamp and write it to a hidden field in the html update form. When they click save: Select the timestamp from the db based on the primary key (index covered so should be fast). If it matches the one sent from the form you're safe to do the update. Else redisplay the form (fresh record from db including fresh timestamp) with message "Changes could not be saved as this record has been updated since you displayed it." If the message causes upset then start saving the name of who updated the record along with the timestamp, and displaying it with the message. Then the users can blame each other instead of you, and they'll quickly learn not to leave half-finished work when they go to lunch ;) Or if it's not a small community then display the time they originally selected the record - you get the idea. hth, hope it made sense!
