Hi-
I'm creating a database of music bands with their cds and songs.
I'm trying to program an SQL statement so that I can enter a string of
text in a textbox, press the 'Enter' key, and have it return the
associated records to a listbox. Once the listbox has the records, I
want to select a record, which will open a form associated with the
selected record in the listbox.

Hello,
I have a ListBox control on a form.
I add members of a class to the Items collection. They show up and I can
select them. The text shown is from my classes ToString override.
Now, later on I need to update this item. I find it in the Items collection
and update a member used by the ToString member function. However, the text
shown for the item in the ListBox does not change.

Hi,
I have 2 listboxes. The first gets populated from the db as soon as
the page loads. The second listbox get populated based on the user's
selection from the first listbox. However, currently the code is
such that with each selection there is a postback. We want to avoid it
using filter and javascript. I am not using ADO.NET but adodbc and no
datagrids or datasets (please don't tell me that i should as my boss

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)..

Help! I have two ListBox controls on my web form. The first one gets
populated on entry with values from the DB. I then use JavaScript to copy
options from this ListBox to my second one. (I have also tried changing the
second ListBox to an HtmlSelect control) using bog standard JavaScript code
like so where "used" is the name of my <select> control:
used.options = new Option(name, typeId);
This all works fine and I can move across...

Hello all:
Clearly, I'm not getting it! Here is the scenario:
On a web page, I have two list boxen and a text box. The first listbox
is populated at page load time (if it is not a postback). This listbox
has AutoPostback = True. When the user selects an item from this list,
the second listbox is populated with more items relevant to this
selection. I am using an SQLDataSource web control for this. These
items are headers. I want, when...

I have a .net app that a user currently enters a number in a text box,
hits a button and a data call is executed. She wants the ability to
enter in multiple numbers (up to 100).
So to make things look better visually for that, I created a listbox
under the text box. She enters the number in the text box, clicks
another button I added and the number is stored in the list box. Then
my plan was to grab all those numbers from the list box...

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,...
