Hi there,
In my application I have a panel that contains a matrix of user controls.
The user control is fairly simple. It merely draws a circle that represents
an object in my code. The object has certain properties that can be
configured, so each control has a context menu that allows such operations.
However, my application requires setting properties for multiple objects at
once. That would require being able to select multiple...

I am having a hard time understanding the logic behind the Rectangle object.
My problem has to do with the way the rectangle treats the "Width" property.
For example, take the following rectangle object.
Rectangle myRec = new Rectangle(0, 0, 2, 2);
If you draw this rectangle on the screen you will end up with a rectangle
like the one shown below (The character "X" represents a pixel used to draw
the rectangle and the character "O" is...

Hi, this is a really simple question I have been banging my head on a
brick wall over.
The program below changes the background colour of a form depending on
whether the cursor is inside a rectangle drawn on the form or not. It
works perfectly as shown below.
But it won't work if I change the values of scaleFactor, rotateFactor,
translateFactorX, translateFactorY in the program. I would like to
'correct' the values of e.X and e.Y in...

Hi,
I would like to know How I could draw a Dashed rectangle over everything in
a container. I will use this to draw a selection rectangle (like in VB.NET
Form Designer UI). And even it draws in invert colors I think, but this is
not necessary for now.
Can I do this with a usercontrol ? Because I know that transparency is a
little tricky in VB.NET, for usercontrols.

Hello All,
I'm trying to solve a nagging problem. The goal is to draw a rectangle over
the top of all the other controls on a form. Specifically, over a ChartFX
control. The user would draw the rectangle using the right mouse button to
represent the area of the chart they want to zoom on. I haev been able to
draw the rectangle on a blank form but I cannot get it to draw on top of
other controls. I have pasted in the code i am using ....

I want to create a custom UI element which will be a custom rectangle object
in a c# XAML application. I'm new to XAML and c# as most of my experience
has been using vb with sql. I'm building a simple Visio type app where I
can drag rectangles on a canvas to create diagrams. for now I don't need
fancy shapes so I'll just start with a rectangle class where I can add
custom properties to it such as where lines are connected to it, etc. ...

I am drawing a rectangle on a picture that has already been drawn
on the graphics area (a user control). It works something like this:
//in the MouseDown event
m_isDragging = true;
m_oldX = e.X; //save original positions
m_oldY = e.Y;
//in the MouseMove event
if (m_isDragging)

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

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...
