Afternoon all,
Cheers to anyone who can help! So far this forum has been a big lifeline to me!!
I believe this to be the last hurdle before my database is complete!
Problem - I have a main form with 3 subforms. Each subform is hidden until it is made visible through use of a check box (code has been written to only allow one box to be visible at any one time). These had been working perfectly but all of a sudden I have begun to get the error message
"The data has been changed. Another user edited this record and saved the changes before you attempted to save your changes"
This is hard to believe as i am the only person using the database. I have found a few articles relating to this but no-one ever suggests a possible fix for this problem.
The Microsoft site says to fix the problem to add "Me.Parent.Requ ery" to the AfterUpdate event on the subforms. This does work but now when you try to change subforms using the check boxes, the 1st click on a check box appears to trigger the AfterUpdate but then you have to re-click the same check box to acctually change forms.
i.e. to change to Travel Subform from Cars you have to click the Travel Check Box, wait a second or two, and then click the Travel Check Box again to actually get it to change.
Seems a little pedantic i know but it just makes the form non user friendly.
Open to suggestions!! Cheers.

In Tools - Options under the Advanced tab.
Is your Default Record Locking set to Edited Record?
Is Open databases using record-level locking ticked?
Default Record Locking is set to "No Locks"
The Open databases using record-level locking is ticked.

Change Default Record Locking set to "Edited Record" and comment out the Me.Parent.Reque ry code. Does this solve the problem?

Alas not,
Commenting out the Me.Parent.Reque st code allows me to switch between the subforms on a single click but I now get the error message again (Record locking changed to "Edited Record")
The subforms update perfectly well regardless of the error message. Is there anyway to disable certain error messages so the code carries on unhindered?

When you click the tickboxes are the subforms just switching from invisible to visible?
Yes, the check boxes only change the visible state from true -> false (or vice versa). On the main form the 3 subforms are on top of one another. I read articles about over laying. Half said dont do it, the other half said its fine as long as you dont need to change the layout later.

I've used a similar procedure before. The record shouldn't be trying to update just because the subform is going invisible.
Are your tickboxes based on a option group or are they individual?
The tickboxes are individual

The tickboxes are individual
Can you post the code for one of the tickboxes with the Me.Parent.Reque ry included.

Hello All,
I have a popup form that is called from a command button on the main

Hi,
we're using Access97 as frontend to a Oracle db. In Access we have a

All worked well until yesterday. We dublicated some records for a new

Hi everyone,
How do you detect that a form element has been changed? This thread:
http://groups.google.com/group/comp.lang.javascript/browse_thread/thread/9ae1c9d419264380/125a82c9be127790?lnk=st&q=checking+html+form++(updated+OR+edited+OR+changed)&rnum=28&hl=en#125a82c9be127790
suggests that you attach onChange event handlers to every form element,
and when the handler fires you update a global 'isChanged' variable.
This technique...

Hi,
I have a form with unbound fields on it. The user selects a record
from a recordset and I populate the unbound fields. When I try to
change the unbound quantity text box, Access 2003 tells me "The data

changes before you attempted to save your changes. Re-edit the
record."
This does not always happen. And yes, I can re-edit the quantity text

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
