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:

I have an ArryList that I'm using as a datasource for a combobox. As an item is selected in the combobox and processed I'd like to remove it from the combobox. When I try I get an error stating that the arraylist is being used as a datasource and can't be updated. I can't remove it as the datasource for the combobox so I can update it and reassign it back as the datasource. Anyone got a workaround?

I want to remove the item from the combobox, but can't because I can't remove the ArrayList as being the datasource of the combobox so I can remove the item in the ArrayList and then assign it back as being the datasource of the combobox.

Dim intPOS As Integer = cboAdvanceResponse.SelectedIndex

I have a combobox that I use to display the advertising medium that
attracted a client. On the Client's table is the foreign key
AdvertisingMedium, and the combobox successfully reads the data from
the AdvertisingMedium table by using a Category class to read the data
into an array. I then set the datasource to read the array into the
combobox.
With cboAdvertisingMedium
.DisplayMember = "Name"
.ValueMember = "ID"

Hello Everyone,
I would like to format the Display Members of a combobox's datasource. Is
there a way to apply a format without subclassing the original datasource?
For example, given a list of decimal values, format them as currency values
with a leading currency symbol and 2 decimal places.
TIA

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

All the examples I've seen showing how to populate a combobox using the
DataSource property and an ArrayList show the ArrayList object
containing objects with at least two properties. I want to create an
ArrayList that contains only rows of string data and want to assign
this to the DataSource but I can't figure out what to set the
ValueMember or DisplayMember to. Example
ArrayList myData = new ArrayList();
myData.Add("abc");

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...

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,...

Hello
I'm a network technician in training and I need your help.
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...
