asked on
the data has been changed another user edited this record
i have a main form and a subform to show the details.
in the main form there are two field i am looking.
One is a read only field named named MinorityContent.
other is text box to enter a percentage (%) named MinorityContentPercent.
I have an event in for that to multiply the above 2 fields and show in the read only field.
Private Sub MinorityContentPercent_Aft
Dim MinorityContent As Currency
MinorityContent = some value from the subform using Dsum function.
Me!MinorityContent = MinorityContent * Me!MinorityContentPercent
End Sub
Then in the subform if the user changed any number i need to repopulate the above read only filed named Me!MinorityContent.
To do that i have an event in the Form_afterupdate EVENT like this
Forms![Job Revision - form].Form![Job Revision - subform]!MinorityContent = MinorityContent * Forms![Job Revision - form].Form![Job Revision - subform]!MinorityContentPe
where MinorityContent is a variable calculated (same as the one above).
Now my problem is that if i edit the minority content in the main form and then changed any thing in the subform and then edit the value in the subform i get a warning that the data has been changed another user edited this recordvalue and saved it error.
How can i avoid this error.(It is in my local machine -no one is editing it aother than me)

Harfang thanks for the reply.
record selector was enabled.
so i added the dirty flag to the following events
in the main form and sub form's form current events( first line)
Private Sub Form_Current()
Me.Dirty = False
and the subform's exit event
Private Sub Revision_Detail_Exit(Cance
Me.Dirty = False
Still i get the same error.
Is that the right place i added the code?

These are two places where a save has no effect. On current, the form just reached a record and did not have time to edit anything yet, and on exit of a subform, the subform's record is saved automatically. However, you write "Me.Dirty=False", meaning to save the main form when you exit from the subform. That normally occurs automatically before you enter the subform.
I was thinking about your code really. Just before and just after you try to write something into a form. The error message is ultimately caused by the fact that you mix different ways to edit the same piece of information, and that Access doesn't follow. The idea was to catch the pencil appearing on a record selector when you edit something elsewhere...
Maybe you should just call the routine of the main form each time, instead of having a distinct version? If you create a public function on the main form called MinorityCompute(), you could call it through "Me.Parent.MinorityCompute

Thanks for the detaild explanation.
i need to find the sum at two places.
one is, if the percentage is changed in the main form then i do this to find the new amount.
Private Sub MinorityContentPercent_Aft
Dim MinorityContent As Currency
MinorityContent = some value from the subform using Dsum function.
Me!MinorityContent = MinorityContent * Me!MinorityContentPercent
End Sub
that alone is okay.
Now the 2nd case.
If the user changed data in the subform, i need to calculate the MinorityContent again.
So i put the same code in the main form under the subform's exit event
Private Sub Revision_Detail_Exit(Cance
Dim MinorityContent As Currency
MinorityContent = some value from the subform using Dsum function.
Me!MinorityContent = MinorityContent * Me!MinorityContentPercent
end sub
as soon as i put this code, problem starts.
In addition to this all the controls are bound controls.
When i edit the subform, the main form's pencil is not appearing.
i tried to put the code in a public function also. Agian i get the same error.
I will double the points, if you can help me to fix this never ending erro i am facing.

That is a very good advice.
If I want to go behind the form's back" with an update query in the sub form, what event is good for that?
Thanks

It would be the subform's AfterUpdate event. At that moment, you know that something has changed (not necessarily affecting the sum, but something), or been added, and that the changes have been successfully written to disk. A query would thus see the latest change.

But for some reason AfterUpdate event is not firing for subform.Is that happend to you any time?
to fix it i had to cut the code and select the event from the drop down down list and paste it.
i do not know why

> Is that happend to you any time?
Yes. For an event procedure to run, you need two things: the string "[Event Procedure]" on the property sheet, and a well-formed Sub (correct name and argument list) in the form's module. Normally, the string [Event procedure] is inserted automatically when you create the Sub in VB, but depending on how you do things, this might fail. If the property is blank, Access simply does not generate the event.
Any luck with the update query / recordset update?

Yes. it is working.
Thanks a lot for your help.
I posted the same question so many times in the past.This is the first time i got areply.
I am just wondering, is there any way you can give me your email address.
If you can, please email me to ai0419@wayne.edu

That is fine.I just want to get your attention.But still i could not find your email id in the profile page.
For all your forms (main, sub, sub-sub) enable the record selector. Watch the pencil. If the pencil is vivible, the record is being edited. You will see that it's not saved at times you think it should be, so use any amount of Me.Dirty=False or Me.subform.form.Dirty=Fals
