Code for Filtering from Mult-select List Box Criteria

Hello Everyone,

I have a main form with a datasheet subform that I use to query by form.
After the user selects two criteria on the main form and clicks the
cmdShowResults button on the main form, the subform returns the records
based on the two criteria. The criteria used on the main form are values
selected in two list boxes. When the user clicks on the first list box
(lstCollege), it returns values in the second list box (lstAcadPlan) based
on the first. The user then clicks on the cmdShowResults to filter and
return records in the datasheet subform. This works fine except for one
problem. Both list boxes are set up for single select values--I now need to
make the second list box (lstAcadPlan) a multi-select list box and pass the
values to the filter. I have no idea how to include that in my code and was
wondering if anyone had any ideas on what I should do. Here is the code I
have so far that works fine as long as only one value is selected in the
second list box:

Private Sub cmdShowResults_Click()
Me.sfrmSearchResults.Visible = True
Me.lblSubformInstructions.Visible = True
Dim strWhere As String
Dim rst As Recordset

If Len(Me.lstCollege & "") > 0 Then
strWhere = "[College] = '" & Me.lstCollege & "'"
End If

If Len(Me.lstAcadPlan & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [AcadPlan] = '" & Me.lstAcadPlan &
"'"
Else
strWhere = "[AcadPlan] = '" & Me.lstAcadPlan & "'"
End If
End If
Forms(Me.Name)("sfrmSearchResults").Form.Filter = strWhere
Forms(Me.Name)("sfrmSearchResults").Form.FilterOn = True
End Sub

Thank you,

William
 
On my website (see sig below) is a small sample database called
"CreateQueries2.mdb". Form 6 in this database illustrates how to create a
Where condition in code with a multi-select listbox. See the code behind
the form for details. In broad outline, it will work something like this:

For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) & "', "
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ");"

This code loops through the values in the listbox. When it reaches one that
is selected, it adds to the Where clause. When it reaches the end, it lops
the last comma off of the Where clause.

(The actual syntax of the strWhere clause will vary depending on details of
your listbox control.)
 
Thanks Roger,

I tried your code. I get a run time error and when I go to debug, it seems
to have combined the college and academic plan. For example, strWhere
filter should show "[College] = CAS and [AcadPlan] = Art, Or Philosophy, Or
History". But it is showing [College]=CAS, Art, Philosophy, History."

OK. Sorry, I missed a bit. Try this:

strWhere = "Where [College] = '" & Me.lstCollege & "' and "
strWhere = strWhere & "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then

This is aircode and not tested but close enough for you to play with

msgbox "Please select the college and then the academic plans."
else
Dim strWhere as string

Thanks Roger. I used your code and it works great. I'm trying to modify it
now for two reasons. Now, I have to add some more search criteria (State,
HonorsCollege, EMPLID, LastName) on the main form. Second, I need the user
to be able to select from the college list without being required to select
from the AcadPlan list.

Here's what I have that works so far:

Private Sub cmdShowResults_Click()
Me.sfrmRoundUpSearchResults.Visible = True
Me.lblSubformInstructions.Visible = True
Dim strWhere As String
Dim rst As Recordset

strWhere = strWhere & "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) & "', "
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ")"

Forms(Me.Name)("sfrmRoundUpSearchResults").Form.Filter = strWhere
Forms(Me.Name)("sfrmRoundUpSearchResults").Form.FilterOn = True

==================================

Now here is what I have added. The good news is it doesn't return any
errors. The bad news is it doesn't filter any records:

Private Sub cmdShowResults_Click()
Me.sfrmRoundUpSearchResults.Visible = True
Me.lblSubformInstructions.Visible = True
Dim strWhere As String
Dim rst As Recordset

If Len(Me.lstCollege & "") > 0 Then
strWhere = "[College] = '" & Me.lstCollege & "'"
End If

If Len(Me.lstAcadPlan & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) & "', "
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ")"
Else
strWhere = "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = "'" & lstAcadPlan.Column(0, i) & "', "
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ")"
End If

If Len(Me.lstHonors & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [HonorsCollege] = '" & Me.lstHonors &
"'"
Else
strWhere = "[HonorsCollege] = '" & Me.lstHonors & "'"
End If

End If
If Len(Me.cboState & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [State] = '" & Me.cboState & "'"
Else
strWhere = "[State] = '" & Me.cboState & "'"
End If
End If

If Len(Me.txtEMPLID & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [EMPLID] = '" & Me.txtEMPLID & "'"
Else
strWhere = "[EMPLID] = " & Me.txtEMPLID

End If
End If

If Len(Me.txtLast & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [Last] = '" & Me.txtLast & "'"
Else
strWhere = "[Last] = '" & Me.txtLast & "'"
End If
End If

Forms(Me.Name)("sfrmRoundUpSearchResults").Form.Filter = strWhere
Forms(Me.Name)("sfrmRoundUpSearchResults").Form.FilterOn = True

Thanks again for your help. It is much appreciated.

When you say it does not filter, do you mean All records are returned or No
records are returned?

Well, I see some obvious problems, none of which may be the major cause.

1) This section:
If Len(strWhere) > 0 Then
strWhere = strWhere & "[AcadPlan] IN ("
Click to expand...

should have an AND like so:
If Len(strWhere) > 0 Then
strWhere = strWhere & " AND [AcadPlan] IN ("
Click to expand...

2) This section:
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [EMPLID] = '" & Me.txtEMPLID & "'"
Else
strWhere = "[EMPLID] = " & Me.txtEMPLID

End If
Click to expand...
is using two different datatypes. If EMPLID is text, the first should be
used, if it is numeric, the second should be used

3) This is not causing a problem yet, but may in the future. If you have a
person with a Last name of O'Brien, this code will fail:
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [Last] = '" & Me.txtLast & "'"
Else
strWhere = "[Last] = '" & Me.txtLast & "'"
End If
Click to expand...

To fix, replace each apostrophe (') with TWO quotes ("")
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [Last] = """ & Me.txtLast & """"
Else
strWhere = "[Last] = """ & Me.txtLast & """"
End If
Click to expand...

Now, as I said, these may not be the cause of the problem at hand. The best
thing to do in a situation like this is to put the following line:

Debug.Print strWhere

just before the filtering line. Then put a break point on the first filter
line. The code will stop before the filter executes and if you look in the
Debug (Immediate) window, you will see exactly what your Where clause looks
like. You can even cut and paste it into a query and see what it is
acutally returning or what error messages it produces.

Sorry for the confusion. Regarding the filtering problem, all records are
being returned. Also, I don't quite understand the If Len(strWhere). I'm
not sure which sections you are referring to. Should I be using that
instead of say, If Len(Me.lstCollege & "") > 0 Then.....................

Click to expand...

Now, as I said, these may not be the cause of the problem at hand. The best
thing to do in a situation like this is to put the following line:

Debug.Print strWhere

just before the filtering line. Then put a break point on the first filter
line. The code will stop before the filter executes and if you look in the
Debug (Immediate) window, you will see exactly what your Where clause looks
like. You can even cut and paste it into a query and see what it is
acutally returning or what error messages it produces.

now for two reasons. Now, I have to add some more search criteria (State,
HonorsCollege, EMPLID, LastName) on the main form. Second, I need the user
to be able to select from the college list without being required to select
from the AcadPlan list.

Here's what I have that works so far:

Private Sub cmdShowResults_Click()
Me.sfrmRoundUpSearchResults.Visible = True
Me.lblSubformInstructions.Visible = True
Dim strWhere As String
Dim rst As Recordset

strWhere = strWhere & "[AcadPlan] IN ("

Forms(Me.Name)("sfrmRoundUpSearchResults").Form.Filter = strWhere
Forms(Me.Name)("sfrmRoundUpSearchResults").Form.FilterOn = True

==================================

Now here is what I have added. The good news is it doesn't return any
errors. The bad news is it doesn't filter any records:

Private Sub cmdShowResults_Click()
Me.sfrmRoundUpSearchResults.Visible = True
Me.lblSubformInstructions.Visible = True
Dim strWhere As String

Thanks Roger,

I tried your code. I get a run time error and when I go to debug, it
seems
to have combined the college and academic plan. For example, strWhere
filter should show "[College] = CAS and [AcadPlan] = Art, Or Philosophy,
Or
History". But it is showing [College]=CAS, Art, Philosophy, History."

On my website (see sig below) is a small sample database called
"CreateQueries2.mdb". Form 6 in this database illustrates how to create
a
Where condition in code with a multi-select listbox. See the code
behind
the form for details. In broad outline, it will work something like
this:

For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) & "', "
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ");"

This code loops through the values in the listbox. When it

reaches
one
that
is selected, it adds to the Where clause. When it reaches the
Click to expand...
Click to expand...
end,
it

Sorry for the confusion. Regarding the filtering problem, all records are

Roger Carlson said:

records are returned?

Well, I see some obvious problems, none of which may be the major cause.

1) This section:
If Len(strWhere) > 0 Then
strWhere = strWhere & "[AcadPlan] IN ("
Click to expand...

should have an AND like so:
If Len(strWhere) > 0 Then
strWhere = strWhere & " AND [AcadPlan] IN ("
Click to expand...

2) This section:
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [EMPLID] = '" & Me.txtEMPLID & "'"
Else
strWhere = "[EMPLID] = " & Me.txtEMPLID

End If
Click to expand...
is using two different datatypes. If EMPLID is text, the first should be
used, if it is numeric, the second should be used

3) This is not causing a problem yet, but may in the future. If you
Click to expand...
have
a
person with a Last name of O'Brien, this code will fail:
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [Last] = '" & Me.txtLast & "'"
Else
strWhere = "[Last] = '" & Me.txtLast & "'"
End If
Click to expand...

To fix, replace each apostrophe (') with TWO quotes ("")
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [Last] = """ & Me.txtLast & """"
Else
strWhere = "[Last] = """ & Me.txtLast & """"

Roger,

The debug idea sounds great. I'm trying it right now with no luck though.
nothing shows up in the immediate window. This is what I have:

If Len(Me.lstCollege & "") > 0 Then
Debug.Print strWhere
strWhere = "[College] = '" & Me.lstCollege & "'"
End If

I have set a breakpoint at strWhere = "[College] = '" & Me.lstCollege & "'"
and opened the immediate window. I select the first two criteria on the
form and click the show results button and the line strWhere = "[College]
= '" & Me.lstCollege & "'" gets highlighted in yellow but nothing shows up
in the immediate window.

Sorry for my numerous posts trying to get this thing done!

Put the Debug line at the bottom of the procedure just above:
Forms(Me.Name)("sfrmRoundUpSearchResults").Form.Filter =
Click to expand...
strWhere

Where you have it now displays nothing because strWhere has not yet been set
to anything. You can also move the line around to different points in the
procedure to see what the Where clause looks like at each point. This is
only used for development, however and should be commented out for
production as it uses up processing time.

No
records are returned?

Well, I see some obvious problems, none of which may be the major cause.

1) This section:
If Len(strWhere) > 0 Then
strWhere = strWhere & "[AcadPlan] IN ("

should have an AND like so:

If Len(strWhere) > 0 Then
strWhere = strWhere & " AND [AcadPlan] IN ("

2) This section:
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [EMPLID] = '" &
Click to expand...
Click to expand...
Me.txtEMPLID
&
"'"
Else
strWhere = "[EMPLID] = " & Me.txtEMPLID

End If
is using two different datatypes. If EMPLID is text, the first
Click to expand...
should
be
used, if it is numeric, the second should be used

3) This is not causing a problem yet, but may in the future. If you have
a
person with a Last name of O'Brien, this code will fail:
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [Last] = '" & Me.txtLast & "'"
Else
strWhere = "[Last] = '" & Me.txtLast & "'"
End If

To fix, replace each apostrophe (') with TWO quotes ("")

If Len(strWhere) > 0 Then
strWhere = strWhere & "And [Last] = """ & Me.txtLast & """"
Else
strWhere = "[Last] = """ & Me.txtLast & """"
End If

Now, as I said, these may not be the cause of the problem at hand. The
best
thing to do in a situation like this is to put the following line:

Debug.Print strWhere

just before the filtering line. Then put a break point on the first
filter
line. The code will stop before the filter executes and if you look in
the
Debug (Immediate) window, you will see exactly what your Where clause
looks
like. You can even cut and paste it into a query and see what it is
acutally returning or what error messages it produces.

Thanks Roger. I used your code and it works great. I'm trying to
modify
it
now for two reasons. Now, I have to add some more search criteria
(State,
HonorsCollege, EMPLID, LastName) on the main form. Second, I need the
user
to be able to select from the college list without being required to
select
from the AcadPlan list.

Here's what I have that works so far:

Private Sub cmdShowResults_Click()
Me.sfrmRoundUpSearchResults.Visible = True
Me.lblSubformInstructions.Visible = True
Dim strWhere As String
Dim rst As Recordset

strWhere = strWhere & "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) & "', "
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ")"

Forms(Me.Name)("sfrmRoundUpSearchResults").Form.Filter = strWhere
Forms(Me.Name)("sfrmRoundUpSearchResults").Form.FilterOn = True

==================================

Now here is what I have added. The good news is it doesn't return any
errors. The bad news is it doesn't filter any records:

Private Sub cmdShowResults_Click()
Me.sfrmRoundUpSearchResults.Visible = True
Me.lblSubformInstructions.Visible = True
Dim strWhere As String
Dim rst As Recordset

If Len(Me.lstCollege & "") > 0 Then
strWhere = "[College] = '" & Me.lstCollege & "'"
End If

If Len(Me.lstAcadPlan & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) & "', "
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ")"
Else
strWhere = "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = "'" & lstAcadPlan.Column(0, i) & "', "
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ")"
End If

If Len(Me.lstHonors & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [HonorsCollege] = '" &
Me.lstHonors
&
"'"
Else
strWhere = "[HonorsCollege] = '" & Me.lstHonors & "'"
End If

End If
If Len(Me.cboState & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [State] = '" & Me.cboState
Click to expand...
&
"'"
Else
strWhere = "[State] = '" & Me.cboState & "'"
End If
End If

If Len(Me.txtEMPLID & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [EMPLID] = '" &
Click to expand...
Click to expand...
Me.txtEMPLID
&
"'"
Else
strWhere = "[EMPLID] = " & Me.txtEMPLID

End If
End If

If Len(Me.txtLast & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [Last] = '" & Me.txtLast & "'"
Else
strWhere = "[Last] = '" & Me.txtLast & "'"
End If
End If

Forms(Me.Name)("sfrmRoundUpSearchResults").Form.Filter = strWhere
Forms(Me.Name)("sfrmRoundUpSearchResults").Form.FilterOn = True

Thanks again for your help. It is much appreciated.

William







OK. Sorry, I missed a bit. Try this:

strWhere = "Where [College] = '" & Me.lstCollege & "' and "
strWhere = strWhere & "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) &
Click to expand...

End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ");"

Thanks Roger,

I tried your code. I get a run time error and when I go to debug,
it
seems
to have combined the college and academic plan. For example,
strWhere
filter should show "[College] = CAS and [AcadPlan] = Art, Or
Philosophy,
Or
History". But it is showing [College]=CAS, Art, Philosophy,
History."

On my website (see sig below) is a small sample database called
"CreateQueries2.mdb". Form 6 in this database illustrates
Click to expand...
how
to
create
a
Where condition in code with a multi-select listbox. See
Click to expand...
the
code
behind
the form for details. In broad outline, it will work something
like
this:

For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i)
Click to expand...
&
"',
"
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ");"

This code loops through the values in the listbox. When it
reaches
one
that
is selected, it adds to the Where clause. When it reaches the
end,
it
lops
the last comma off of the Where clause.

(The actual syntax of the strWhere clause will vary

depending
on
details
of
your listbox control.)

Hello Everyone,

I have a main form with a datasheet subform that I use to query
by
form.
After the user selects two criteria on the main form and clicks
the
cmdShowResults button on the main form, the subform
Click to expand...
returns
the
records
based on the two criteria. The criteria used on the main form
are
values
selected in two list boxes. When the user clicks on the first
list
box
(lstCollege), it returns values in the second list box
(lstAcadPlan)
based
on the first. The user then clicks on the cmdShowResults to
filter
and
return records in the datasheet subform. This works fine except
for
one
problem. Both list boxes are set up for single select values--I
now
need
to
make the second list box (lstAcadPlan) a multi-select list box
and
pass
the
values to the filter. I have no idea how to include that
Click to expand...
in
my
code
and
was
wondering if anyone had any ideas on what I should do.

Here
is
the
code
I
have so far that works fine as long as only one value is

in
the
second list box:

Dim strWhere As String

Hello Again,

I finally was able to play around with the debug feature and can at least
see results. Here are the ongoing problems I'm having.

1. I can't get the results from the lstAcadPlan list box selection to
concatenate with other criteria (I get a run time error).
2. If I only want to choose an item from one of the criteria (lstCollege
for example), I also get a run time error.

When I use just the following code by itself, it works--as long I select one
item from the lstCollege list box and any number of items from the
lstAcadPlan list box.

strWhere = strWhere & "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) & "', "
Debug.Print strWhere
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ")"

Here is what is displayed in the debug window (I selected three academic
plans):

[AcadPlan] IN ('BA-AFROAM',
[AcadPlan] IN ('BA-AFROAM', 'BA-ANTH',
[AcadPlan] IN ('BA-AFROAM', 'BA-ANTH', 'BA-ART',


If I add the following to the code above and select the AcadPlan AND State,
I get a runtime error 2448 (can't assign a value to this object). If I
select just the State and I get the same run time error.

If Len(Me.cboState & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [State] = '" & Me.cboState & "'"
Debug.Print strWhere
Else
strWhere = "[State] = '" & Me.cboState & "'"
End If
End If

Here is what then gets displayed in the debug Window

[AcadPlan] IN)

It should be returning

[AcadPlan] IN ('BA-AFROAM', 'BA-ANTH', 'BA-ART', AND [State] = 'MA'

Thanks for your help...

William

Actually, you should get a return string like this:

[AcadPlan] IN ('BA-AFROAM', 'BA-ANTH', 'BA-ART') AND [State] = 'MA'

The AND State = 'MA' should be outside the closing parenthesis of the
IN() clause. You're neglecting to put the closing parenthesis after
the last selected item in the ListBox.

Here is a function I created to get items from ListBoxes (Acc97):

Under the Case dbText, if using Access 2000 & greater use:

Replace(lst.ItemData(row), "'", "''")

instead of

ReplaceStr(lst.ItemData(row), "'", "''", 0)


Public Function getIDs(lst As Control, ByVal intType As Integer) _

' In:

' intType One of the dbText, dbDate, dbTime, dbNumeric

' If the intType is undefined an empty string is returned.
' Created:

Why don't you go one step further with all the excellent help and put
the code to generate the IN clause in a reusable function?

eg
Public Function GetListBoxValues(byref plst as Listbox,
Optional Byref pblnIsString as Boolean) as string
' IN : plst - a multi select list box
' pblnIsString 0 - '[value]' if True, [Value] if False
' OUT: A string representing the innards of your IN Clause
'
your previous code...(with a few mods)

End Function

usage

Function BuildWhereClause() as string

dim strWhere as String

If me.lstWhatever.ItemsSelected.Count > 0 then
if Len(strWhere) > 0 then strWhere = strWhere & " AND "
strWhere = strWhere & "SomeField IN(" &
GetListBoxValues(me.lstWhatever, True) & ")"
end if

etc

BuildWhereClause = strWhere

End Function

Just would seem to me to make the whole thing a little more reusable
and flexible....

Thanks for everyone's generous help on this....still trying to work through
it.

MG, I've tried putting a closing parentheses at the end of the line but it
won't let me....

I'm trying to change this:

strWhere = strWhere & "[AcadPlan] IN ("

to this: strWhere = strWhere & "[AcadPlan] IN (")

But I get an error message that says, "expected end of statement. Where
should the closing parentheses be?

Here's all of my code again:

strWhere = strWhere & "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) & "', "
Debug.Print strWhere
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ")"

Thanks,

Hello Again,

I finally was able to play around with the debug feature and can at least
see results. Here are the ongoing problems I'm having.

1. I can't get the results from the lstAcadPlan list box selection to
concatenate with other criteria (I get a run time error).
2. If I only want to choose an item from one of the criteria (lstCollege
for example), I also get a run time error.

When I use just the following code by itself, it works--as long I select one
item from the lstCollege list box and any number of items from the
lstAcadPlan list box.

strWhere = strWhere & "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) & "', "
Debug.Print strWhere
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ")"

Here is what is displayed in the debug window (I selected three academic
plans):

[AcadPlan] IN ('BA-AFROAM',
[AcadPlan] IN ('BA-AFROAM', 'BA-ANTH',
[AcadPlan] IN ('BA-AFROAM', 'BA-ANTH', 'BA-ART',


If I add the following to the code above and select the AcadPlan AND State,
I get a runtime error 2448 (can't assign a value to this object). If I
select just the State and I get the same run time error.

If Len(Me.cboState & "") > 0 Then
If Len(strWhere) > 0 Then
strWhere = strWhere & "And [State] = '" & Me.cboState & "'"
Debug.Print strWhere
Else
strWhere = "[State] = '" & Me.cboState & "'"
End If
End If

Here is what then gets displayed in the debug Window

[AcadPlan] IN)

It should be returning

[AcadPlan] IN ('BA-AFROAM', 'BA-ANTH', 'BA-ART', AND [State] = 'MA'

Thanks for your help...

The In() clause should be formatted like this (string items):

IN ('item2', 'item2', 'item3')

The closing parenthesis is after 'item3' - this indicates that the
list (the values inside the parentheses) is ended.

Your post indicates you don't understand how to concatenate strings in
VBA, but your For...Next loop looks like it should produce a correct
IN() clause - IF any items are selected; otherwise, you'll have a
Where string like this:

[AcadPlan] IN () -- an empty list, which causes an error.

You can check for selected items by:

If Me!lstAcadPlan.ItemsSelected.Count > 0 Then
' There are selected items
... etc. ...

You could put a break-point on:

strWhere = Left(strWhere, Len(strWhere) - 2) & ") "

step thru it (F8) to the next command and print the value of the
variable strWhere in the debug window:

? strWhere

to see if it is formatted correctly.

Thanks for everyone's generous help on this....still trying to work through
it.

MG, I've tried putting a closing parentheses at the end of the line but it
won't let me....

I'm trying to change this:

strWhere = strWhere & "[AcadPlan] IN ("

to this: strWhere = strWhere & "[AcadPlan] IN (")

But I get an error message that says, "expected end of statement. Where
should the closing parentheses be?

Here's all of my code again:

strWhere = strWhere & "[AcadPlan] IN ("
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
strWhere = strWhere & "'" & lstAcadPlan.Column(0, i) & "', "
Debug.Print strWhere
End If
Next i
strWhere = Left(strWhere, Len(strWhere) - 2) & ")"

Thanks,

William

Actually, you should get a return string like this:

[AcadPlan] IN ('BA-AFROAM', 'BA-ANTH', 'BA-ART') AND [State] = 'MA'

The AND State = 'MA' should be outside the closing parenthesis of the
IN() clause. You're neglecting to put the closing parenthesis after
the last selected item in the ListBox.

Here is a function I created to get items from ListBoxes (Acc97):

Under the Case dbText, if using Access 2000 & greater use:

Replace(lst.ItemData(row), "'", "''")

instead of

ReplaceStr(lst.ItemData(row), "'", "''", 0)


Public Function getIDs(lst As Control, ByVal intType As Integer) _
As String
' Purpose:
' Get a list of the item IDs into a comma separated string
' In:
' lst A ref to a list box control
' intType One of the dbText, dbDate, dbTime, dbNumeric
' Out:
' A string of comma-delimited IDs. Format: "1,2,3,4"
' If the intType is undefined an empty string is returned.
' Created:
' mgf 8mar2000
' Modified:
' mgf 10mar2000 Added intType selection
'

Dim row As Variant
For Each row In lst.ItemsSelected
Dim strIDs As String
Select Case intType
Case dbText
strIDs = strIDs & "'" & _
ReplaceStr(lst.ItemData(row), "'", "''", 0) & "',"
Case dbDate, dbTime
' Assumes USA date format mm/dd/yyyy
strIDs = strIDs & "#" & lst.ItemData(row) & "#,"
Case dbNumeric
strIDs = strIDs & lst.ItemData(row) & ","
Case Else
' Don't know how to handle this type
Exit Function
End Select
Next row

' Return string w/o trailing comma
getIDs = Left$(strIDs, Len(strIDs) - 1)

End Function

It is called this way:

' Check if any data in ListBox
If lstAvailable.ItemsSelected.Count > 0 Then
Dim strResult As String
' Get selected items IDs
strResult = getIDs(lstAvailable, dbNumeric)
strWhere = " Items In (" & strResult & ") "
End If

Thanks again to all of you and this invaluable newsgroup!

Why don't you go one step further with all the excellent help and put
the code to generate the IN clause in a reusable function?

eg
Public Function GetListBoxValues(byref plst as Listbox,
Optional Byref pblnIsString as Boolean) as string
' IN : plst - a multi select list box
' pblnIsString 0 - '[value]' if True, [Value] if False
' OUT: A string representing the innards of your IN Clause
'
your previous code...(with a few mods)

End Function

usage

Function BuildWhereClause() as string

dim strWhere as String

If me.lstWhatever.ItemsSelected.Count > 0 then
if Len(strWhere) > 0 then strWhere = strWhere & " AND "
strWhere = strWhere & "SomeField IN(" &
GetListBoxValues(me.lstWhatever, True) & ")"
end if

etc

BuildWhereClause = strWhere

End Function

Just would seem to me to make the whole thing a little more reusable
and flexible....

Well, first off, well done on getting it to work. Now that it works,
it might be time for some tweaking...

Instead of looping through all the items in the listbox and seeing if
they're selected...
For i = 0 To lstAcadPlan.ListCount - 1
If lstAcadPlan.Selected(i) Then
Click to expand...

Why not use the ItemsSelected collection of the listbox and just do
the same thing? Won't make much of a difference if you don't have a
ton of items in your listbox, but if you do, it could make your app
run faster...

dim varItem as Variant
For each varItem in lstAcadPlan.ItemsSelected
'do something
Next varItem

there's code that shows how to do this at www.mvps.org/access

look for something like "listbox" + varitem and you'll find an example
of iterating through the list of selected items...

HTH,
Pieter
