Combo Box not working

418 256MB
Hello all:

I could not get a combo box to display a list in a Search Form. My object is to select an artist's name and have his/her CDs listed on the subform through a qry. But I couldn't do it. When I tried to type an artist's name, I get an error message telling me the name does not exist in the list. I was successful in getting data by typing a CD title but couldn't get the Combo box for the Artist's search to work. Can someone please help?

Details follow:

Table 1: tblArtists
ArtistID - Auto (PK)
ArtistName- Text

Table2: tblCDDetails
RecordID - Auto (PK)
RecordingTitle - Text
ArtistID - FK

Table 3: tblzNull
ItemID - Auto (PK)
ItemName - Text

Query 1: qryCD
RecordingID
RecordingTitle
ArtistID
ArtistName


Main Form 1: frmFIND
Text box 1 = txtCDTitle (Unbound)
Combo Box 1 = cboArtist (Unbound) but has this code under Row Source

Expand|Select|Wrap|Line Numbers
  1.  
  2. SELECT 0 as ArtistID, "<ALL>" as ArtitstName FROM tblzNull UNION ALL SELECT tblArtists.ArtistID, tblArtists.ArtistName FROM tblArtists

Sorry for the long note. But felt that details may help you understand my problem better. Many thanks.

Have a look at Example Filtering on a Form and see if you can do it after that.

If not, please come back and let us know in here. We will expect you to be familiar with what's in that thread though.

I read the instructions you sent CH 1 -7 plus the article by RABBIT. Thanks.

I still need help.

My Combo Box on the main form is called cboArtist

Column Count = 2
Bound Column = 1

Control Source = Unbound
Row Source Type = Table/Query
Row Source:
Expand|Select|Wrap|Line Numbers
  1. SELECT 0 as ArtistID,
  2.        "<ALL>" as ArtitstName
  3.  
  4. FROM tblzNull
  5.  
  6. UNION ALL SELECT ArtistID,
  7.                  ArtistName
  8.  
  9. FROM tblArtists
  10.  
  11. ORDER BY ArtistName;
It does not display any Artistís name. When I try to execute the FIND button, I get this error message:

The ORDER BY expression (ArtistName) includes fields that are not selected by the query. Only those fields requested in the first query can be included in an ORDER BY expression.

I am not at all GOOD with SQL commands and am learning as I go. My query name is qryCD lists ArtistName to be sorted. Why do I get this message then?

So I edited the SQL to read it as
Expand|Select|Wrap|Line Numbers
  1. SELECT 0 as ArtistID,
  2.        "<ALL>" as ArtitstName
  3.  
  4. FROM tblzNull
  5.  
  6. UNION ALL SELECT ArtistID,
  7.                  ArtistName
  8.  
  9. FROM tblArtists;
This allows me to see the list of Artistsí Names. But when I select one name and Click on FIND button I get this weird error message which I donít understand at all.

Run-Time Error Ď2001í:
You canceled the previous operation
END DEBUG

I chose DEBUG which takes me to the VBA page and Line 3 (below) is highlighted in yellow.
Expand|Select|Wrap|Line Numbers
  1. Private Sub cmdFIND_Click()
  2.   ' Update the record source
  3.   Me.sfrmCD.Form.RecordSource = "SELECT * FROM qryCD " & BuildFilter
  4.  
  5.   ' Requery the subform
  6.   Me.sfrmCD.Requery
  7. End Sub
PLEASE HELP. Is it possible to attach a smaller version of my Database here?

I appreciate your time. Thanks.

I took the liberty, while I was editing your post to include the [ CODE ] tags, of reformatting your SQL code too (just for visual display - not to change the effect).

You will notice more easily now that the field [ArtitstName] on line #2 of each is misspelled.

In a UNION query, the field name is ALWAYS determined by the first query, so the subsequent query that's UNIONed with it, doesn't matter - even though it is spelt correctly there.

For your code breaking (at line #3 shown) I can't help too much as most of the information is not available to me. I have no info about qryCD or BuildFilter.

What I can say though, is that rather than changing the .RecordSource, it's probably easier simply to set the .Filter itself and call a .ReQuery. The .ReQuery you have on line #6 seems wrong to me too. It is the form that needs to be requeried and not the subform control (which can contain a subform).
Expand|Select|Wrap|Line Numbers
  1. Me.sfrmCD.Form.Requery
As to attaching a database, it is possible, but personally I would not do it unless requested. I see it as shorthand for "I don't want to go to the effort of explaining my problem clearly. I'd prefer if you spent you time trying to work it out instead".

Some experts do request it and that's absolutely fine, but if not requested then it's better not to in my view.

To get this, simply, when you have selected DEBUG, do the following :
  1. Type Ctrl-G to open and select the Immediate Pane
  2. Type in ?BuildFilter
  3. Copy the results displayed in with your next post
It may be clear and simple from whatever it displays, but we may need to know a bit more about [qryCD] if it's not.

Thank you for taking the time to explain things to me. I sincerely appreciate. I am happy to report that I was able to fix this problem. All I needed is to add the column number to the SQL under ArtistID. In the event someone else could benefit from it, here is the revised code:
Expand|Select|Wrap|Line Numbers
  1. ' Check for RecordingArtistID
  2.     If Me.cboArtist > 0 Then
  3.         varWhere = varWhere & "[RecordingArtistName] = '" & Me.cboArtist.Column(1) & "' AND "
  4.     End If
Many thanks for your help. I am still struggling with the problem of creating a text box to automatically populate with running numbers.

Thank you for posting your answer. That always helps.

I'm not sure from your last what, if anything, you still want help with.

If there is still something you need perhaps you could explain it again to save me trying to determine by rereading everything from scratch.

Thank you and my apologies for not being clear.

I was able to solve the problem that you tried to help. I was referring to another problem I am still struggling with.

So where is this other problem explained? If you drop in a link I will have a look.

It looks complicated, but I'll have a longer look sometime and see if I can decipher it.
