Working on a windows form, I am trying to bind a listbox to a dataset and
want to set the displaymember & Valuemember properties of the listbox so that
I can retrieve the selectedvalue from a selecteditem in the listbox.
My code is very simple:
lstReports.DataBindings.Clear()
lstReports.DataSource = dsDataSet.Tables("Reports")
lstReports.DisplayMember = "ReportDescription"
lstReports.ValueMember = "ReportsKey"

I am populating a multiselect Listbox from a dataset, with the content of
the listbox filled by one table, and the selections determined from another
table. So far, I have been keeping the dataset a denormalized mirror of the
database, but I'm not having much luck getting the selection logic down (I
haven't found a 'hook' where I can access the listbox object as an object to
set the listitem's selected property before it gets rendered)..

I have a strange problem with a databound listbox. It may be because of how
I use it, but I am stumped by this behavior. Here is the scenario:
I have a multiselect databound listbox that belongs to a panel control. In
the Page_Load event, the panel listbox control may be moved from one panel
to another depending on selections that the operator makes. Everything
seems to work fine except for one thing. The selections that are made in...

Hi guys,
Recently i read some articles on Longhorn & XAML.
& From what i learnt the future for developing UIs lies in XAML.
Does this mean that I've got to learn XAML as developing UIs for web or win
applications will be different?
Or will future versions of VS.Net wrap up the XAML hence making it
unnecessary for me to know or learn XAML?

Hi everyone,
I have a ComboBox that when changed, calls a method to change the content of
a ListBox.
I'm also using the Listbox's SelectedIndexChanged event to change other
control values on the form.

When I bind my datasource to the ListBox, I find that the

Hi,
After viewing the entire Visual Basic 2005 Express Edition for

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:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
