Hi, All,
I'm using MS.net 2003 and using a windows.forms.listbox control for my
window application but I don't know why the Horizontal Scrollbar could NOT be
shown even if I set HorizontalScrollbar = true. The text info in listbox
already beyond its right edge. How can I see the hidden part info in listbox?
here is a part of codes.
ListBox.ValueMember = XX
ListBox.DisplayMember = XXXX

Hey All,
I am having a little trouble with the ListBox's Items collection property. I
am populating the ListBox with data contained in an SQL table using
SQLDataAdapter and DataSet.
I have set the "DataSource", "DisplayMember", and "ValueMember" properties
of the ListBox correctly like below:
lbTechnician.DataSource = TechnicianDataSet.Tables;

I have the following bit of code (which works fine):
Dim Customer As New CCustomer
mFrmOrder.lstCustID.DataSource =
Customer.getCustomers.Tables("data")
mFrmOrder.lstCustID.DisplayMember = "surname"
mFrmOrder.lstCustID.ValueMember = "custID"
mFrmOrder.lstCustID.Refresh()
mFrmOrder.lstCustID.ClearSelected()
Customer = Nothing

The problem is this:
I have a list box. I set an array list as the datasource. I remove an item
from the array list. I set the listbox datasource to nothing. I set the
listbox datasource to the array list again to refresh. Click on an item in
the list, and an Indexing error comes up. (in non-user code, it is trying to
get an element from the array that is greater than the number of items in the
array.)
To reproduce:

Hi all,
I have a listbox that is complex bound by an arraylist. The problem is that
when I delete an object from the arraylist, the listbox does not reflect
those changes. I tried refreshing the listbox with no luck and, because it
is already bound, I can't just delete the item directly from the listbox
without an error (because it already has a datasource, you are not allowed
to delete/add anything to the listbox directly).

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:

I'm trying to fill a listBox control with string members from an array
of objects. I think using data binding is supposed to be the easiest
way to do this. I've never used data binding before and am having
trouble getting it to do anything. The relevant code is below, followed
by a better explanation of what I'm trying to do.
// pseudocode start
public delegate string StepMethod();

Hello All,
I know this is a re-post, but I didn't get any bites on my last post. So here goes again:
I have a listbox which is bound to a datatable. I have set the displaymember and valuemember and all works well:
the user dbl clicks an item in the list box, I use the valuemember to retrieve some values from the db. However, I would like
a label to display the displaymember value that was selected by the user. I am assuming this is a...

Hi
NET1.1 / Winforms
I have a listbox that I am binding to a table via the DataSource property.
However I want to be able to programmatically select values in this listbox

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
