I thought that you it is forbidden to create an instance of an interface.
But a help example (search for Explicit Interface Implementation Sample)
from visual studio has the following sample code:
// Declare an instance of the English units interface:
IEnglishDimensions eDimensions = (IEnglishDimensions) myBox;
// Declare an instance of the metric units interface:
IMetricDimensions mDimensions = (IMetricDimensions) myBox;

Let's suppose I have an instance of MyClass, which has the properties
MyText1 and MyText2, and sets the values of MyText1 and MyText2 to 'A'
and 'B' in it's constructor.
Let's also suppose I have a Form with textBox1, textBox2, btnShowValue,
and btnNew.
Let's also suppose I have this code.

Business Entity object (based on generated classes from EntitySpaces) I've
left the default column setup so that all the columns are displayed.
My DataSource objects are composed like this:

that was generated

I am not a programmer, I'm an engineer trying to make an interface to a
product I'm designing. I have used C# to make a form that interrogates the
unit via the serial port and receives the data. I want to be able to draw
lines in a picturebox based upon certain data points I have received. I
dragged a picturebox from the toolbar onto my form, but after having gone
through the help files, looking online and trying a variety of things, I...

Hello all,
Ok, I want to create a program that will load plugins (dll's) from a
plugin folder. I can create the forms and put them into a dll but I
cannot actually add them dynamically at run time. I have tried to use
the LoadLibrary and GetProc functions, which sort of worked. I got
the pointer to the function but I cannot actually RUN the function
like I can in C++. I have heard some things about Invoking(?) I
believe but I cannot...

Hello, I've taken over a .net 2.0 project that makes heavy use of Data
Binding of business classes to 3rd party WinForm controls via the
BindingSource class and INotifyPropertyChanged interface.
The setup in generally works ok, but the app feels sluggish. Because
BindingSource is basically a black box, I am having trouble determining
where the sluggishness comes from: BindingSource or 3rd party controls.
or a combination thereof.

Hello:
I'm working on improving some of our Windows Forms.
I have created two user controls that I want to bind to the same

I have an overview control that is used just to identify a customer.
Then there is a details view that shows all their specifics. I wanted

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

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...
