I have a databound combobox within a datagrid. I have set the DisplayMember

BUT, how do I capture the Value (SelectedValue) when the user changes the
selection?

Hello,
I know this has been discussed a lot already because I've been searching
around for information the last few weeks.
I'm trying to implement a DataGridComboBoxColumn class. I've found
several examples on the web. They all seem to have problems, though
that I've been unable to resolve.
The most promising example I have found is at:

Using .Net CF, i have created a 2 dimension ArrayList, and "binded" this list
to a ComboBox control using the "DataSource" property. I have set the
DisplaySource and ValueMember properties as well. The control populates well,
both the display values, and selected values.
However, when i try to "set" the SelectedValue or SelectedIndex properties,
nothing happens.... The default blank value in the ComboBox is always
selected. My code is:

tried the following:

Shouldn't I be able to set the selected item of a combobox with the
SelectedValue property? The ComboBox has four items, the values are 1
through 4. Here's an example of what I'm trying to do:
Sub SetLevel(Level as Short)
cboLevel.SelectedValue = Level
End Sub
I try this assignment, and the SelectedValue property remains Nothing. I
know for sure that the Level variable is within the 1 - 4 range, and no

ComboBox databindng Problem
== How the ComboBox is setup and used:
My comboBox is populated by a lookup table. The ValueMember is the
lookup table's Id and the DisplayMember is the text from a
corresponding field in the lookup table. In my data table we store the
ID in what I will call the 'key' field.

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

Can I use a bound ComboBox for both browsing and editing?
I'm working on a small, standalone database application using Visual
C#.NET 2003 and an Access data file.
In order to keep the number of different screens down to a minimum,
I'm trying to use the same Windows Forms for both browsing and for
updating. This works fine for TextBoxes, but I'm running into
problems with my DropDownLists (ComboBoxes).

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,...
