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

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...

HI,
I need to populate 2 listboxes from a db. When the page loads then the
first listbox needs to be populated and based on selection from that
listbox the second listbox needs to be populated accordingly with the
matching items.
However, my boss doesn't want the page to do a postback once an item
from the first listbox is selected. also, he doesn't want to use
ado.net but classic ado.
He wants to use jscript. I am writing my code in...

Hi all
I have a listbox which is 5 rows high. There are 5 list items. The
first one is selected. I wish to click on a button and have the
selection focus on the listbox removed. Removed, unselected,
nullified?!
cheers

I've just spend a lot of time solving the following problem:
I used dotNet 2.0 / Visualstudio 2005 / C# / aspx, enable viewstate is
set on all controls.
I have 2 listboxes; the left contains items that can be (dynamically)
added to the right box.
Adding the first item went fine, it shows up in the right box.
Adding the second item resulted in losing _every_ control following the
right box. 'View source' reveiled that the rendering of the...

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 ListBox on a form than has some items. The select mode is one
item only. I select one, it is selected and hightlighted. I then click
somewhere in the listbox not on any item, in the clear area of the
listbox. I would like to unselect the selected item but I cannot
determine which event to use to trap this event and unselect the
current seleted item.
Any help?

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...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
