I am working on an audits database.
The main table, Audits, has an AuditID primary key.
Another table, 1:1 relationship, ProgramAudits, has AuditID as a
foreign key.
I have a master/main form for Audits data, and a child/sub form for
ProgramAudits data.
I put a subform for ProgramAudits onto the Audits table form, and the
following code in the OnCurrent event to grab the AuditID field from
the main form and put it into the AuditID field of the ProgramAudits
subform:
Private Sub Form_Current()
' automagically grab the AuditID and put it in the right field
Me.AuditID = Form.Parent.[AuditID]
Me.Refresh
End Sub
Me is the ProgramAudits subform.
I only want the ProgramAudits table to have one record per Audits table
record, is there a better event or means to achieve what I want to do??
Or is there some uncomplicated way to check if the ProgramAudits table
already has a record corresponding to an Audits table record??
Should I enforce my end users to always manually add the one new
ProgramAudits record per each Audits table record??
One reason I ask is that the above event causes a new record to be
added each time the Audits table main form is opened, and I don't want
to do that, setting AllowAdditions to false for the subform doesn't
work.
I've looked on the forum but so far have not found the right way to
search the groups to know if anyone has solved this question.
Thank you for reading this,

After reading some more, it seems there's no real way to do what I
want, so long as the ProgramAudits table is shown on the Audits form as
a ProgramAudits subform.
Perhaps there is some other way I can programmaticall y set up the
desired record in teh ProgramAudits table each time a new Audits table
record is added.
I will work on this, since I am using custom nav buttons for the Audits
table, one of them is cmdAddNew, maybe this will work better, but I
hope that someone could point me toward displaying this on a subform,
too.
Thank you for reading this,
Tom
A moment of patience...
wait for Tim or Lyle (the big Goons). They know all about that.

Open ProgramAudits in design view; select the AuditID field; and
change its Index from Allow Duplicates to No Duplicates.

You are making this much more difficult than it needs to be.
The subform has a pair of properties, linkChildFields and
LinkParentField s, which will handle the automatic entry of the
foreign key to the sub table.
As to adding the child record, if the user has no additional data
to add, there is no need for the child record. As the user adds the
other required data, the foreign key should automatically be added,
so there is no additional work for the user.
If you still wish to use your code above, you could embed it in an
if condition that tests the subform's .recordcount property and
only sets the Me.AuditID = Form.Parent.[AuditID] if the recordcount
=0

PA is y I've altered my email address.
Hello, I got this figured out.
I did several things:
Code in the SUBform's Current and AfterInsert:
Private Sub Form_AfterInser t()
Me.AllowAdditio ns = False
End Sub
Private Sub Form_Current()
'This is the only required field, all other fields are optional,
'so I fill this in programmaticall y.
If Me.AuditID = "" Or IsNull(Me.Audit ID) = True Then
Me.AuditID = Me.Parent.Audit ID
DoCmd.RunComman d acCmdSaveRecord
Me.Recalc 'To reset txtRecordNos on the form
End If
End Sub
I also set the Cycle Property of the SUBform to stay on the current
record.
In the MAIN form I did:
Private Sub Form_Current()
' (Parent Form)
'test the current record of the MAIN form
If Me.NewRecord = True Then
' Parent form is on a new record
Me.frmProgramAu dits.Form.Allow Additions = True
Else
Me.frmProgramAu dits.Form.Allow Additions = False
End If
End Sub
All but one of the SUBform's fields are locked, only one field is
actually editable, and this is optional.
If anyone has comments, suggestions for improvements, thank you!!
