How to lock record edits on a subform using a checkbox

[Guest]

I want to be able to lock records for editing in a subform by using a
checkbox, i.e. when the checkbox is unchecked the current record on the
subform can still be edited, when the checkbox is checked the record can only
be viewed, not edited. I would also like to attach some kind of password
control to the checkbox to prevent users from unchecking the chkbox to amend
data.

Debra,
Add a new field to the table for your subform (ex. chkLocked -
True/False), and place it your subform.
On the AfterUpdate event of chkLocked use this code...
If chkLocked = True then
Me.AllowEdits = False
Me.AllowDeletions = False
Else
Me.AllowEdits = True
Me.AllowDeletions = True
End If
*Use this same code on the OnCurrent event of the subform record.

That should do it...

Al,

I use a similar checkbox for completed jobs to prevent users from
inadvertently changing data once the record should be "finalized" - however,
if someone checks that box by mistake, then I would have to go back in to
the table to reset it. I got around this by adding a new button which is the
only enabled control on the form, which is visible only if the checkbox =
true, and then having a confirmation dialog box ("Are you SURE you want to
change the status of this job?"

This works fine in my app, but Debra wanted to allow this via security - how
would one set that up? (Assuming, of course, that you already have Access
Security enabled)

TIA,

Susan,
Sorry I missed your post until now...
Well, I don't think Debra meant using the Access security system... just
a simple "password" type check (key users would have this password) before
allowing the chk update. That password would remove the AllowEdits = No.
If you wanted to use Access security, a simple method would be to create
a pop-up form to check uncheck the checkbox. That form could be secured in
Access security to only those users allowed to do so.

Thanks for replying Al - after I sent my response I realized that's what I
would nee to do - check user then if user is allowed, open the popup I have
now to change the checkbox, if user is not allowed, popup a insufficient
rights dialog.
