Selecting mutiple choices from either a list box or combo box? 11

Nate1749 · May 27, 2003

I have a non-normalized .csv file that we get from an external source. It's then linked to an access table. I think have queries that do a Group By to pull out unique instances for certain columns and then that populates the combo/list box's on a form. The selections made on the form is the criteria for a report that is ran. Currently everything works fine, except now I'm trying to figure out how the user can select multiple criteria.

For instance, in cboLocation there is Online, DuPage, Kane.
Currently I can only select one choise and run the report; I'm trying to figure out how I could possibly select two or all three. I changed the combo box to a list box and tried holding ctrl, but no luck.

Thanks Jeff, you code worked, I wont put it up here cause it is the same as the one Nate published.

Thanks idd for all your help too.

Nate1749 · Jun 20, 2003

I meant Jeff!!! Sorry about that Jeff. Thanks for your help too idd.

Mecha, did you get multiple list boxes working? My form (which feeds the report) has 7 of them, Jeff sent me code on how to do it, but it's giving me problems. Thanks,

-Nate

Mecha · Jun 22, 2003

No i am still having problems with the many boxes. i have about 7 as well.

Still having a go at it myself, but i have a feeling i have no idea

Tell me if you have any luck

Hello, I'm new to this thread and tek-tips in general. I was searching for code help when I came across this thread. I am having similar problems as Nate and Mecha above. I have a form with 5 fields. 3 of the fields filter each other. For example, in the first Combo Box I choose a process, then the next Combo Box limits itself to locations containing that process, and the next Combo Box limits itself to machines in that location with that process. The other two fields specify the start and end dates. Ideally, I want to create a report using the selected fields. This works fine, except I am limited to selecting 1 machine in the 3rd field I described. I cant figure out how to choose multiple machines in this last box. I know I will have to change it to a list box, but am not sure of the code I have to use. I am not too experienced with programming, and am looking for some help with this. Any ideas? Suggestions? Thanks

RamziSaab · Jun 27, 2003

nate are these fields from a table...

if so can u tell me table name and the name of the last combobox

Nate1749 · Jul 1, 2003

This is non-working code for the 7 list boxes I have. I figured I would post it and hope someone else tries to poke around at it.

I have tried eliminating part 2 and keeping part 3. I have also tried eliminating all of part 3 and keeping part 2, also tried keeping them both (what's currently below), but it's not working.

You'll see I only labeled Part 1 & 2 on the first two listboxes, the pattern is pretty easy to catch onto.

Hi Nate!

Had last week off so I have been very busy this week. I should have looked at this again last week, sorry for the delay. Some of your values look like they should be text values. If that is the case then you need to add single quotes like this (example):

For Each varRow In ctl.ItemsSelected
If strlbCampus = "" Then
strlbCampus = "[Student Campus] in ('" & ctl.Column(0, varRow) & "'"
Else
strlbCampus = strlbCampus & ", '" & ctl.Column(0, varRow) & "'"
End If
Next varRow

Let me know if that helps.

Jeff, you beat me to it!!! I just found this out and was very happy. I also had vacation all last week. Your help has been greatly appriciated.

I figured it out by looking at the 1st solution you gave me (one listbox) vs. the newest one (multiple listboxes). For anyone who cares, this is my code for 7 list boxes all working. Thanks again Jeff!

Everything works great with this setup, however, I am having a small problem with the loading time. It is taking sometimes 2 minutes to load/save a form. What's strange is if I quit out of access and open it right back up, the load time will be minimal (3-5 seconds), but after a save or two it skyrockets to taking 2 minutes (literally). My computer isn't old (p4 1.8ghz, 512megs on windows 2000), and I had posted this problem awhile ago in another thread, but received no replies. This is the other thread I posted it in thread702-560011

Nate1749 · Jul 9, 2003

if a blank is selected from the query box, it's not pulling any data (even though there are records w/ blanks). I think it's not feeding how a blank should be handled correctly into the query criteria, any ideas?

IE.. The list box for placement status is..
<-this is a blank
e1s
e1d

If someone selects e1d, it pulls all of them; works fine, however, if someone selects the blank (meaning there isn't anything typed in that column for those records), then it's not pulling anything (even though there should be).

jdegeorge · Jul 24, 2003

Nate1749

I'm having the same problem as you, I think. I have about 5 multi-select list boxes on an unbound form that should allow a user to select one or more values from one or more of the list boxes. If a list box has no values, then it shouldn't be added to the filter.

Any way, this works when the user selects something from all boxes but doesn't work if one or more list boxes have no selected values. Were you able to get this to work for you?

I'm desperate and need a way to let my users select their own report filters from 5 fields. Am I going about this the wrong way?

Jim DeGeorge [wavey]

RamziSaab · Jul 24, 2003

I am a bit confused, my for allows the user to select the field and then a list box will appear populated by that field

if the no field is selected in the combobox then the macro will skip it by a simple if statement?

e.g.

if me.cbofieldlist.value = vbnullstring then
else
my code
end if

jdegeorge · Jul 24, 2003

Nate1749 and IDD:

I used a combination of your code and code from others to solve my problem. Enjoy the stars!

idd · Jul 25, 2003

JDEGeorge,

If you don't mind can you post the code in this thread so that others may benefit from it too.

Thanks for the star.

Idd

FancyPrairie · Jul 25, 2003

JDEGeorge put the code in a thread I responded to. However, I modified it somewhat so that it can be a routine that you can call from any report criteria form you create.

Actually, there is a better way of handling this so that the function will not only build the Where clause for listboxes, but also for text boxes, date ranges, etc. But that gets a little more complicated. And that was not the question people asked in this thread or the other.

Note that the routine assumes that the Tag property of the listbox(es) is formatted as Where=TableName.FieldName,DataType,. Where DataType is either the word String or Number. That way the function knows how to format the SQL string.

Also note that the function uses the Bound column of the list box as the value to be included in the Where clause.

Assuming the function encounters no errors, you could call it by passing the form object. Something like this:

Docmd.OpenReport "rptName",intView,,BuildWhereClause(Me)

Code:

Function BuildWhereClause(frm As Form) As String

Sorry about that. I know I should have posted the solution but was so happy it was working that it slipped my mind.

What FancyPrairie posted isn't what I'm using, but rather his streamlined re-write of my code, which I'm trying to figure out how to adapt.

Jim DeGeorge [wavey]

Nate1749 · Jul 25, 2003

No I never did resolve it. I know it's fairly simple to because it's not feeding a blank into the query criteria correctly.

All of the data fields should have something in it anyways (at least in my database), so I thought it would be neat to select the (blank) field and then have it query out all of those records so we go back and correct that record.

jdegeorge · Jul 28, 2003

Nate

FancyPrairie's generic code did the job for me. Check it out! Oh, and enhoy the star FP!

Jim DeGeorge [wavey]

Nate1749 · Sep 21, 2003

I'm still using the initial code by jebry, except now I am having the problem if there is an apostrophe in the criteria.

For example : Kim's Travel is making the code put the ' before it's over so I'm getting a syntax error. I tried a number of ways of adding or changing the punctuation in the code (double quotes, single quotes)... Is there a way around this, or I may be forced to switch to the code fancyprairie posted.

-Nate

jdegeorge · Sep 22, 2003

Check out a thread that I posted. thread705-653379 came to the rescue. His code works perfectly to solve the "single quote in the text" issue! Good luck.
