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 there. I have written a small procedure to draw various shapes on
things. A bit of it is shown below.
Private Sub drawShape(ByVal shapeType As Integer, ByRef g As Graphics)
Select Case shapeType
Case 1 : g.DrawRectangle(New Pen(Color.Black), 0, 0, 50, 10)
Case 2 'draw a circle
Case 3 'draw a triangle
Case 4 'draw other shape
Case 5 'draw other shape

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...

Hey folks,
I'm trying to make my own progressbar. The idea (for my test) is a
rectangle that is 1/60 filled with a color per second (so after a
minute it is all filled).
This is what I have so far:
Public Sub DrawRectangleFloat(ByVal e As PaintEventArgs)

I have a rectangle around text that I want to fill in with color. I do not
know the height of the rectangle until I actually go through and draw out
the text. Is there a way of filling in the rectangle that will allow the
text to show through?
I did try:
myColor = Color.FromArgb(127, Color.GreenYellow)
Dim fillBrush As New SolidBrush(myColor)
but that isn't exactly the effect I wanted.

Hi,
Now I can get the rectangle to draw, but it seems the rectangle is not
visible. The following code is used to draw the rectangle. Hope someone can
help. Thanks very much!
SolidBrush brush = new
System.Drawing.SolidBrush(System.Drawing.Color.Red);
Pen pen = new Pen(brush, 4);
Graphics formGraphics = Graphics.FromHwnd(this.axWebBrowser.Handle);

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'm drawing text using the DrawString method. I need a way to go back and
erase one or more characters. As a first thought it seemed that one way to
do it would be to go back to the character(s) I want to erase and merely
re-write the same character(s) using a brush whose foreground color is the
same as the background color. The following code does that:
protected override void OnPaint(PaintEventArgs pea)
{

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'm particularly interested in Zigbee because I've heard it does some...

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...
