few combox. The lstSchItem has a dataview as a datasource. The comboxes are
bind to its selected value but through the dataset table. Now when I change

design-time. Here is the design of my simple tables: (An example

Hi,
I am strugling with the propertygrid and a listbox. I am using the
universaldropdowneditor from the codeproject (code below). However I am
populating the listbox via a datasource. The problem I am having is that when
I have a value in the propertygird and edit that, I want the listbox to have
the selectvalue equal to the value that is being edited. Just to make it
clearer:
PropgridVal = Germany

Hi,
I thought that this would be a simple exercise but I am struggling to get a
result.
I need a listbox that will display a list of items from a DataTable,
dtUnits. The displayed list comes from Column . Selecting an
item in this list needs to return a value from Column .
Data in dtUnits is

I'm a newbie to c# and could use some help - been banging my head on
the keyboard for 3 days now.
I have an unbound listbox that I'm populating this way:
1. loop through a datatable and load row into row object
2. Check one of the row columns against a dictionary key
3. If it's found, add it to the listbox.
Then I want to pass the actual item that shows up in the listbox

Hi
I Can't get the MSDN's example for Listbox to work.The example is below. I
get an error in Listbox's sub ListBox1_SelectedValueChanged at row
textBox1.Text = ListBox1.SelectedValue and it happens after the line
ListBox1.ValueMember = "ShortName" is run. The error says Cast from type
'USState' to type 'String' is not valid.
I don't know why the code doesn't work, can anyone please explain that for
me.

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,...

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...
