I am trying to populate a combobox with a lisy of items. I want the 1st item
to be "Make a Selection" and the following items will be names from a table
in my DB (See code below).
When I run the project, the combox box initially displays an empty
selection. When I click on the drop down arrow I see the "Make a Selection"
followed by the other choices.
How can I move everything up so that the "Make a Selection" is the default
value in...

Hello,
For my new Windows application, all I want is to create an initial
form to demo to the user to show them how it looks like with some data
on it. So I figure the fastest way is to create some comboBox-es to
show some data on them manually entered in the code without connecting
to the database yet. It should be simple but somehow I can't make it
work.
First, I drag a comboBox from the ToolBox to the form. Then,

Hi All,
How to fill one ComboBox from other ComboBox control?
1) Only setting the reference does the trick but doesn't show items in
control. If you see in immediate window, it shows the item count correctly

I am trying to dynamically add items to a listbox or combobox. The
items add to either, but when I look through those items, there is
nothing there. If I choose an item, it shows up.
Not sure why, but the items are not visible in the listbox or combobox
until one of the items has been chosen. This of course is not good,
since someone can not see the items they need to choose from.
Any help would be appreciated.

I want to create a customized ComboBox where the methods ComboBox.Items.Add
and ComboBox.Items.Insert will behave thusly:
-- If the item is not present, add it.
-- If the item is present, set the selected index to the item (without
adding a duplicate).
I know the basics of inheriting from user controls, so if this was merely
overriding a method of ComboBox I could do it. But how does one go about
overriding a method of the Items...

I'm baffled by this -- is there not a typed object used for ComboBox Items?
Best I can tell, all of the methods for ComboBox that accept an Item are of
type Object. Why in the world is a common/standard .NET control accepting
an Object as a parameter type?
In Web Forms, there is a ListItem object that can be passed in to
add/retrieve objects from a DropDownItems collection. I searched Google
groups, and all the solutions I'm finding...

I want a string of characters that will sort after all strings of Roman
letters.
Something that will display using a font like the one this note is written
with.
Is there such a thing?
I tried using a string starting with { because in ASCII it comes after the
letters but that sorts before the letters.

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

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....
Now, this would greatly impact the work of software developers. The idea...

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...
