I have a listbox with datasource from a dataview. When a user selects a
different item in a combobox then I need to refresh the listbox to the
appropriate listing based on that combobox's selected value which is included
in the listbox's filtering statement.
Is the only way to do this is to dispose the dataview and then create a new
one and then bind it to the listbox? Is there a better way than this?
Thanks, Alpha

Hello All
I have a textbox control. I would like this text box to automatically
update to contain the currently selected item located in a listbox
which is on the same form.
Do I need a CurrencyManager for this? Can this be done just by
manipulating the databindings properties of the textbox? If so, please
do give me some hints as to the syntax I would use to fill in that
field on the property panel - everything I try is rejected.

I have some standard text book type examples of oleDB connections and

What I would like to do is to use a datagrid view instead as the information

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,...

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...
