Open a form to a blank record

I have a button on a parent form that when clicked opens a child form
(popup) and displays a specified record.

The parent form supplies the id field (stLinkCriteria) for the record that
is to be opened in the child as:

DoCmd.OpenForm stDocName, , , stLinkCriteria

But if there is no related record, the button click throws an error.

If there is no related record I would like to display a blank child form.
Or at least a message box saying there is no related record.

Can anyone give me some pointers on how to do this?

Thanks
Dave
 
Hi Dave

What does "throws an error" mean? What error? What is the message?

If your stLinkCriteria is, for example, "EmployeeID=99", and there is no
such employee, then the new form should open on a blank record *unless*
AllowAdditions is turned off, in which case you will get a blank form.

If you are getting an error then something else must be wrong. More
information please!
 
Thanks Graham

The error I get if I try to invoke the child form is a message box that
states:

Syntax error (missing operator) in query expression '[scriptid]='.

The code to open the form is:

stLinkCriteria = "[scriptid]=" & Me![scriptid]
DoCmd.OpenForm stDocName, , , stLinkCriteria


This database manages scripts which are small text files. The parent form
is basically a script record and the child form is some script detail.

The error occurs on new records. So when I move to a new record on the
parent and click the command button to invoke the child, there really isn't
a scriptid to pass to the child yet.

I am looking for some way to invoke the child without having to move off the
parent to commit the scriptid and then return to the parent to access the
child.

Perhaps I should add some code to commit the parent record (and create a
scriptid) prior to calling the child. Is this how it should be handled?

Hi Dave

So what you need to do is check first whether scriptid is Null (blank) and
take different action for that case:

If IsNull(Me![scriptid]) Then
' open the form at a new record
DoCmd.OpenForm stDocName, , , stLinkCriteria, acFormAdd
Else
' open the form at the current script
stLinkCriteria = "[scriptid]=" & Me![scriptid]
DoCmd.OpenForm stDocName, , , stLinkCriteria
End If
