Creating a windows form to edit address records from a SqlServer table, I
want to have a ComboBox for the prefix field (Mr./Mrs./Ms./Dr.). Is it
possible to populate the list in the ComboBox AND use databinding to
load/save the text? Or is it necessary to set up the ComboBox without
databinding and load/save the text with explicit code? The items in the list
can be either fixed, or pulled from the database.

Hi Everyone,
I am at my wit's end here. I have a combobox (combyQueryTitle) that I
need to use in order to select a query for my database project. Therefore,
I am using the comboQueryTitle_SelectedIndexChanged handler to, when a new
selection is made, update the query and refresh the display. The only
problem is that the program seems to inexplicably start with the
..selectedindex property at -1! This makes no sense to me. ...

I have a webservice that I want to populate a combobox on a windows form.
The webservice creates the correct XML output, but when I attempt to bind it
to a combobox I get this error:
Additional information: Cannot bind to property or column FullName on

This error occurs with the databindings. Here is the code:

I'm struggling with combobox databinding with something I consider a bug...
I'm binding my combobox to an array of structs. The struct exposes two
public properties, ID and Name, to be used as the
value and displaymember properties.
This works fine. My combobox contains the correct data.
However I'm also binding my SelectedValue property to a column in a
datatable. Here's where I'm lost. The combobox doesn't show the correct

How can you display more than one field in the displaymember property of a
combobox inside the datagridview control? I am at a loss.
Thanks,

My combobox datasource does not contain ValueMember with null value.
So I tried to create combobox which stores null to bound object when text is

When i attempt to bind to the "Text" and "Value" property of a combobox
on a windows form the value is reset when I leave the combobox. The
comboboxes contain the correct Text and Values. I know this as the Value
property binds correctly on it own. It is only when I bind the "Text"
and "Value" that the issue occurs.
The following sample code includes my custom classes and the Form Clode.
I have several comboboxes and customer classes...

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:

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,...

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
