I checked my color printers's Printersettings.SupportsColor, which all
showed false. What is wrong that I could not use this property.
Also, what other way to detect if a printer is color printer.
TIA

I am using VB 2005 and want to generate a graphic in a picture box control
where the color of each pixel is determined by particular values calculated
for each pixel. These values are manipulated in such a way that I come up
with three values (each in the range 0-155) and I want to use these for the
RGB values of the color of the associated pixel. My question is: In VB
2005 how do I set a particular pixel to a color with a given set of...

Hello. I'm working on a layout that I need to be pixel specific. How
can I get the font to stay precisely the height I need? Specifying
line-height or font-size in px doesn't yield the results I need. The
font size scales when I change the browser's font size and the text
moves from where I need it.

As my first attempt to loop through every pixel of an image, I used
for thisY in range(0, thisHeight):
for thisX in range(0, thisWidth):
#Actions here for Pixel thisX, thisY
But it takes 450-1000 milliseconds
I want speeds less than 10 milliseconds

I want to get the color of the specified pixel in the screen.
Firstly I get the position of the cursor:
//Get the position of cursor.
Point position = Cursor.Position;

Anybody here can show me some demo codes?
Thanks.

I have a Visual basic 3 App that I am converting to VBA in Microsoft Access 2003. The VB3 app successfully recolors a bitmap image with code using pixel locations when clicking on option buttons used for color selection.
An example is:
Grphecho!Picture3.PSet (xpos, ypos), RGB(RRGB, GRGB, BRGB)
where the pixel positions are xpos and ypos in a Picture box(Picture3) using the Pset method.
I know about the need for twips instead of pixels...

hi,
I'm doing a project in c# that removes the green background in a picture, like a green screen effect in movies.
i already made it partially working.
but the problem is that it only remove 1 shade of green at a time. so if i have a 3 shades of green i need to process it 3 times.
but my prof. want it to be done only once.
when i load the picture it must remove all the green background.
do you have any idea to do this.

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,...

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...
