Hello Everyone and thanks for your help in advance. I am
developing a class library that reads a SQL Server table
of names and ID's. I want to populate a dropdownlist with
the data, however, names in the table may appear more
than once. I only want to display the name in the
dropdownlist once. My initial thought wat to create an
arraylist, then loop through each record, adding a new
name upon each new name encountered. But I want the name...

Hi,
I need help populating a listbox from a database on a webform.
I created a an access database with a table, fields and data. Then I
created a WebForm in vb.net and added a DropDownList control to the
page.
Then I created a data connection to my table... I right clicked and
told it to generate a dataset (which it created dataset1).

The method below belongs to a class. The method accepts a
dropdownlist as a parameter. Is there any disadvantage to passing in
the control and having this method populate it as opposed to passing
back a datareader from this method and having the webform populate it?
It seems to work great! Just wondering if there may be a disadvantage
to passing a control.
Oh yea, by the way, it is just passing a pointer to the control,
right? Or...

Hello together,
I tried to find out about populating an asp.net server control (a
dropdownlist) from the clientside jscript, but I didn't find a solution up
to now.
I cannot use a html dropdownlist, because a database query in codebehind has
to be done, when a new listItem is selected. So, I need to use a
servercontrol dropdownlist.
Now to my problem:

Hi all,
I have a MS SQLServer database which has two tables, 'images' and
'photographers'. The photographer table contains a field for
PhotographerID and a one for PhotographerName. The image table also
contains a field for photographerID which is used to join the two
tables.
I'm having problems with populating a dropDownList using the complete
set of photographerNames and IDs from the 'photographer' table but

I have a gridview and a dropdownlist. If I change the ddl, the
gridview populates. That is what I want. But what I don't want is for
it to happen the first time they get to the page. I know I can add a
"Select Item," but is that the correct way to do it? I don't want it
to hit the database at all the first time the page loads. I have done
everything through visual studio and was trying to see if I could do
this with no code behind. ...

I am trying to do something which seems (to me) to be very simple, and
yet I can't seem to figure it out.
I have a gridview and a formview. When a user clicks "select" in the
gridview, the formview opens. The user can then click "insert" or
"update" to either create a new row or edit the existing row.
This all works fine as long as I only use textboxes and checkboxes in
my insertItemTemplate and editItemTemplate. What I would like...

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,...

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...
