If you have a comboBox which has it's DisplayMember and ValueMenber bound
to a datatable.
If I know the "ValueMember" value - is there a way for me to set
the index of the control to correspond to that ValueMember without having
to iterate over the values in the control to find the index of the matching
value menber?
There is a "FindString" method of the ComboBox which apparently iterates
over the collection looking form a match on...

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:

Hi,
I have a combobox who's data source i set to an array of objects (call
it MyObject). these objects have get properties: key, value, descr. i

the array of MyObjects.
How can i set the selected value of that combobox based on the
ValueMember OR how can i find the index of an item in the combobox BY
ValueMember?

OK. So I've been to http://www.syncfusion.com/FAQ/WinForms/FAQ_c44c.asp and learned a lot about what I might do with a datagrid. But I'm STILL not able to do what I want to do. I want to be able be able to enter data into my grid cell using a combobox. I want the combobox to display items based on my selected DisplayMember and update the datasource based on my selected ValueMember. So far, so good. But when the user leaves the combobox...

Table A has 2 columns:
recID int
recName String
I need to load all recName into combobox B using B.Items.Add(recName). This
is no problem.
However, I would like to be able to match ComboxBox B's index with table A's
recID so that I can use B.SelectedIndex to update any table that uses Table
A's recID. Currently, I have to use a clumsy routine to find recID from
B.text

All I want to to be able to take a two-column DataReader (One column with

Completely easy in ASP.NET, but I cannot figure out how to do the same in a

I have a List of data objects.
I need to populate a ComboBox with the 'Description' field from the
objects.
I can do that with cmbBx.Items.Add( myObject.Description.ToString() );
myObject has 2 fields for example. id and description.
Later, I need to get the id of the selected item in the ComboBox...
In Delphi, I'd create a StringList, and add the ID to that, and then

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:

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,...
