Query Refrenced to Form control update problem

[don]

Hi Group,

I have an unbound text box within a form which is referenced in a
query and I've put a sub form based on the query within that form.
Its a search box, and I am having problems getting the query to update
in the sub form to show results. I've tried a macro form update, re-
query and repaint without success. The sub form does update if I put
the form into design then back again so I know the query works I just
don't know how to get it to refresh.

Any help would be appreciated.

Thanks in anticipation.

Don

Don, I've often found this to be the case, so there has to be a better way
of designing the form.

Leave the [Forms].[Form1].[Text0] criteria out of the query. Instead, use
the AfterUpdate event procedure of the text box to apply a filter to the
form, so it shows the results you need.

You can actually adapt this approach to handle any number of text boxes
where the user can enter their limiting criteria. Here's a downloadable
example to play with:

If you don't like writing code, and only need one search box, this one is
just copy'n'paste to set up:

Allen,

Thank you very much for your reply and links. Just at the end of my
day and the wife beckons, will try your suggestions tomorrow.

Thanks again.

Allen,

Thanks very much got a handle on how it worked and was able to apply
that to my Db.

BUT sadly I got another problem because of this. My original search
query used the result of the search to append an address id number
into a table. Can your method append?


Thanks in anticipation

[Allen Browne]

So you need to append record(s), using the same WHERE clause as you used in
your search?

Execute an append query, perhaps in the Click of a command button.

If you need help in how to execute such an append query statement, see:

[don]

Allen,

I've read your linked info and I cannot see how to apply it to my
situation. I am a novice in this field. Can you offer more of an
explanation linking my needs to your suggestions please.

As a recap. I want a form to look up address information. Depending
on level of information at hand I would ideally want to search using a
number of different criteria. Your original suggestion fullfills
that. I then need to be able to select my search result and have an
id number within that result appended to a new record within my
tblContacts.

Any help with this would be appreciated.

 

[Allen Browne]

I can't write that for you, Don.

Once you have achieved the search form, you have written a filter string (or
a whole query statement including a WHERE clause.) Presumably this query
string gives you the resultant ID value you want to append. You therefore
execute a Append query statement, to append that ID value to the target
table.

Allen,

I don't expect you to write things for me but I'm struggling with
understanding. I'm using

as per your web site and dont understand how this then links in with


Function UnpickAll()
Dim db As DAO.Database
Dim strSql As String

strSql = "UPDATE Table1 SET IsPicked = False WHERE IsPicked =
True;"
Set db = DBEngine(0)(0)
db.Execute strSql, dbFailOnError
MsgBox db.RecordsAffected & " record(s) were unpicked."
Set db = Nothing
End Function

I just don't know enough, I think I'm getting confused because I'm
using a filter not a query?

A filter is the same as the WHERE clause of a query.

Allen,

I've spent a couple of days trying to understand this and havent been
able to get the final bit working. I've tried building an append
query with refrence to one of the unbound boxes in the search and
inserting the SQL into your VBA function but that doesn't work for me
and I cant see how your explanatory text from your web site is applied

It is also much more flexible: you can build the SQL string from only those boxes where the user entered a value, instead of trying handle all the possible cases.

In the absence of understanding I shall have to go back to my very
clunky way of doing things.

Thanks for your help


Don
