In a C# program I have an SQL database.
A data adapter is connected to the database and a dataset
has been generated.
I would like to populate a listBox (or comboBox) from the
dataset such that the user can select a record to be
edited.
I would like to have the user be able to select the
information to populate the listBox from a number of
sorted database fields. ie: sorted ID#, sorted age,
sorted LastName, sorted years of service, etc.

I'm open for any suggestions on how to better program this. I want the user
to select a license from a combo box, cboPrivilege and then the user will
click the add button, then a record will be added to the data grid.
My current code is coming up with errors, dt and drv are unknown in the else
part of the if statement.

I'm trying to populate a ComboBox (dropdown style) with strings of text
from an ArrayList. The ComboBox is actually being populated with the
correct items, however, they appear only as blank entries on the drop
down list. When I click on one of the blank entries, the editable
region displays the correct text, and subsequent functions relying on
this string execute properly. My question is why can't I see any of
the values that have been...

Help Please... I would like to populate a combo box on a form with a
query that compares data from two tables. Any record that is unique in
table1 should continue to populate my combobox. The instant the record
appears also in table2 it should no longer be listed in my combo box.
This is not a key field in either of the tables. Basically what I am
trying to do is prevent the user from entering duplicate values even
though it is not a key...

Hello,
I have a search application to search data in tables in a database (3 sql
server tables). I populate 2 comboboxes with with data from each table. One
combobox will contain unique CompanyID's. The second combobox will contain

respective tables. Like

Hi. New member here
Im sat at work, pounding my head off the desk because this tiny bit of simple code refuses to work.
The sub is intended to pull data from the "companyname" column in the "cmSelectAllCompanyNames" table, and put all the company names it finds into the "cbFilterCompanyName" combo box.
Now the confusing aspect is this:
It works!!!

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...

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,...
