Hi
I'm using Acces 2003
I have Query where the several parameters for the criteria are supplied from a form. One parameter source is a combo box. What I am trying to do is if:
An item is selected on the combo box then that value is used as the criteria
If user does not want the contents of the combo box used, then Query should ignore that field.
I have tried to do this with an iif statement in the query criteria and a control box on the form.
i.e in the criteria for that field use
iif([forms]![formname]![option10]=-1,[forms]![formname]![combo0],Like"*")
[option10] being the control
This works when the condition is true, ie a person wants to use the combo box and has selected a value. It does not work for the false condition. What I was expecting to happen is since that the control box is not selected(iif is false) all records are returned by the query using like"*".
Any suggestions, alternative approaches?
Thanks

That's because iif returns a string and a string is never evaluated. Use: - Like iif([forms]![formname]![option10]=-1,[forms]![formname]![combo0],"*")
Hi
Thanks, But what happens now is that the false condition works and the true condition does not. It seems that for example the criteria does not evaluate
Like oven#1
the same as [forms]![formname] etc.
oven #1 being the selection from the combo box
Would the # be the problem in the value?
thanks

The following characters would cause problems because the Like operator uses wildcards.
So if you want to return oven#1 then the combobox has to pass oven[#]1 to the query.

Hi Folks,
I've been trying to build a query from a form of dialogue boxes I

been able to get the query to retrieve the data selected in the
relevant dialogue boxes and perform the query on these boxes. However
my problem lies in the fact that if no choice is selected in the
dialogue box I want the query to default (or get passed) a wildcard
that will mean it will...

Hi Everyone-
I have a question about how to add and then use the "All" selection in
a combo box. I am trying to figure out how to:
(1) add "All" as a selection to a combo box and then
(2) how to use the selection "All" as criteria for a field in a
query, which is used to generate data for a report.

I have a database of employee data in access and I am trying to create

I have a form (Form1) that displays records based on 3 unbound combo boxes that are also on my form. My record source for this form is a query “ReQryForecast” (which looks at those combo boxes via the criteria setting of that query). If changes are made to one of the combo boxes, the records displayed will change via my simple code in the after update event of my unbound combo box.
This works fine….
Now I have a command button on Form1...
