Why doesn't this code work:
-------------------------code snippet-----------------
Dim categorysource As String
categorysource = "SELECT [KSTUDY_KSTUDY].[KSTUDY_ID],
[KSTUDY_KSTUDY].[KSTUDY_CATEGORY], [KSTUDY_KSTUDY].[KSTUDY_WHO]" & _
" FROM KSTUDY_KSTUDY " & _
" WHERE [KSTUDY_KSTUDY].[PRSTUDY_ID] = " & Me.List0.Value
Me.List4.RowSou rce = categorysource
Me.List4.Requer y
-------------------------code snippet--------------------
I put this as an afterupdate event. Basically, I have two listboxes.
LIST0 has a list of records from the KSTUDY_PRSTUDY table. There are
only 2 fields in this table. PRSTUDY_ID and CATEGORY. I display
Category, but hide the PRSTUDY_ID. PRSTUDY_ID, however, is the key
column, and is also the bound column. So, when I select one of the
categories, the value of P101, P102, etc is selected. All well and
good.
I put the above code in the AFTERUPDATE event of LIST0. Unfortunately,
it does appear to be updating the rowsource of LIST4 properly.. but I
can't, for the life of me, make it update the listbox and display
anything. It just sits there empty.
Any ideas? 2 1670

Since the column PRSTUDY_ID is a char column, you have to delimit the
value in quotes:
"WHERE [KSTUDY_KSTUDY].[PRSTUDY_ID] = '" & Me!List0 & "'"

I'm not at work now to try it out.. (the tables are actually linked Oracle

I have have two list boxes. One is a listing of all possible variables.

Hi all,
After unsuccessfully trying to make my own dual listbox control out of
arraylists, I decided to look for a 3rd party control. I've looked for over
a week now and can't find anything but ASP.Net stuff when I need a Windows
Form control. I've seen dual listbox populators in countless Windows
applications, and have seen them run very fast, so I figured this would be
extremely popular.
Here's how it should work:

Hi. I have a form with a listbox and a few label fields all bound to a
dataset. When i navigate the listbox the labels change accordingly. so far
everything works good.
I made a button to delete a record. I delete the row from the datatable and
update the database with the adapter and that all works good. The record is
removed from the listbox.
Here is my problem.

I am trying to dynamically add items to a listbox or combobox. The
items add to either, but when I look through those items, there is
nothing there. If I choose an item, it shows up.
Not sure why, but the items are not visible in the listbox or combobox
until one of the items has been chosen. This of course is not good,
since someone can not see the items they need to choose from.
Any help would be appreciated.

I tried to fill a ListBox with a DataSource pointing to an ArrayList.
It all works fine...up to one point.
The ArrayList is dynamic, which means the contents of it change, during the course of program use.
But instead of Updating the ListBox, virtually nothing happens. The items that were written into the ListBox during the first run remain inside the ListBox, assuming the new values of the ArrayList. Obviously, if the new ArrayList is...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
