I have the following Custom Control that uses a DataTemplate and is Bound to
a LightBox object. The template does bind correctly to properties directly on
the LightBox object. However my LightBox has a list of Lights and I want to
bind the List of lights in the DataTemplate somehow?
My attempt to solve the problem was to create a custom control that defined
a depencency property and set the dependency property in the DataTemplate. It

I was just wondering, when you create dataContext methods, should you put
business logic there to try and minimize pushing data through 2-3 layers of
code? or should the business logic still go in another class somewhere
making it access the dataContext methods?

I have a stored proc that selects all from a database table. I drug it from
the server explorer onto the o/r designer to make it part of the
dataContext. Now I can't figure out how to use it. I don't think I know how
to use the ISingleResult type since that is what it returns from what I can
see. Any examples of how to do this? any examples I can find are either
incomplete, or bad examples. The dataContext is called TestXmlDataContext,

Hello,
I'm creating a WCF service in which I use LINQ to SQL to do all my data access.
I have a couple of architectural questions about using LINQ to SQL from WCF
services:
1) What is the right way to use DataContext in this scenario?
The service will obviously be used by multiple clients simultaneously. Should

Hello,
I have a ComboBox that has a DataContext set on it. When a PropertyChanged
event is fired (based on a static instance of some class), I'd like to update
the DataContext on the combo, but it seems that I need to set it to null
first:
Combo1.DataContext = null;
Combo1.DataContext = dc;

Hi,
Is there any benefit to store a datacontext singleton in an application
variable?
Should I bother?
Should I just create an instance of my datacontext every time my business
objects need it?

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...

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'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.

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...
