Dear colleagues,
I refer to your help with specific graphic problem. It is
necessary to create a viewfinder in graphic application.
It seems that the algorithm is simple: just draw lines
in specific position in according to value of some
controls, track bars, for example. Next read the track
bars value to find the coordinates of lines cross.
It works, but I can not get real cross because the
background image is being deface by lines...

consisting of a specified number of squares. I can get it to draw the grid
and activate the autoscroll feature, however I cant get it to scroll
properly. I dont want to make the grid a bitmap and move that as the grid
can get very large and I want to keep memory and performance as high as
possible.
Is there an easy way to get the grid to to scroll so that...

I need to create a label with the last character drawn in red.
My idea was to create a label and override OnPaint.
So far so good.
I then measure the character range for the last character.
All good.
Then when I call drawstring and pass the rectangle I get via
Region.GetBounds(Graphics) it draws it with the same offset as the
beginning of the label.
Not good.

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,...

Hello
I'm a network technician in training and I need your help.

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...
