need to know total number of items in the listbox and pass the value to an integer
Posted on 2006-10-25
I am designing a Form application in Access 2003.
I have a listbox containing data populated on basis of a selection in a combo box. I need to pass the rowcount of the listbox to an integer variable for furthur process. my combo box contains Date, my list box returns customer names for a Date selected.
I thought about two different approaches, but not successful yet.
1. I want to Dim ListControl as Control, try to use ListCount.
2. I tried to use Dcount function which needs taking the value of selection of the combo box as criteria in the function. I can write a query as expression to get same records as those populated in the list box.
Dcount("customer", "qry", "orderdate = Form!frm_master!cbo_orderD
Any ideas? Thanks

And using DCOUNT
If within the sama form, just do this
Dcount("customer", "qry", "orderdate = #" & Me.cbo_OrderDate & "#")
otherwise
Dcount("customer", "qry", "orderdate = #" & Form!frm_master!cbo_orderD
If within the sama form, just do this
Dcount("customer", "qry", "orderdate = #" & Me.cbo_OrderDate & "#")
otherwise
Dcount("customer", "qry", "orderdate = #" & Form!frm_master!cbo_orderD
And yet summat else, which I forgot to post
If your combo has 3 columns say, selecting the value (bounded column) may not be the one u need
therefore u can specify what column u want
col 0 is 1st column of data
col 1 is 2nd, etc
Dcount("customer", "qry", "orderdate = #" & Me.cbo_OrderDate.Colum(0) & "#")

U may perhaps need to wrap OrderDate with CDATE but I think u should be ok
Im off home now, see ya all

Rockiroads, my combo box only has one column. The filed name OrderDate is just example name I used to discribe in this case. My real database, tables and fields are with very complicated business concept, and hard to post them in few lines. Then I use customer and their order as example case in here.
Thank you everyone.
Thank you everyone.

as posted above
dim x
x=me.listboxname.listcount
is enough to get the number of items from the listbox
if you want to use dcount, try this
Dcount("customer", "qry", "cdate(format([orderdate],

ok jc50967w, where are we at this
you now know how to get a listcount and Ive told you about the error you had in your dcount
I mentioned the multicolumn just in case, but its not a problem now since u only have the one column.
Did the correction to the DCOUNT work? (after u change it to your fields that is)
