Dear all..
I have a picturebox filled on a form. The picturebox has some
graphics displayed on it.I was trying to save the picturebox, but
continuesly failed to do so. I am clueless of why it is happening. I
tried to save the image of the form & also the picturebox, but always,
i see a blank file saved. Is there a way to save whatever is displayed
on the picturebox, to a file??
Thanks for any suggestions and help.
Regards,

I have a picturebox on my VB.NET form. The picturebox size mode is set to
stretched. I then load an image into that form and display it. As the user
moves the mouse over the form, I want to get and display (in the status bar)
the image coordinates of the mouse location. However, if I use the
picturebox's MouseMove event, I am getting the coordinates of the mouse over
the PICTUREBOX, not the actual image underneath that (which is stretched)....

Have used DrawLine() method to draw some lines in the picturebox (sort
of a barcode) in the picturebox paint event.
This diagram has to be saved as an image in bmp or tiff format.
But the problem is that these lines are not recognized as the image of
the picturebox.
It shows picturebox.image = nothing.
How do we convert these lines drawn as the image of the picturebox so
that it can be saved.

I am using a network camera that saves the image in a byte array in memory
(via their ocx component, and in the OnNewImage event I can get the pointer
to the image and the byte length as
e.lFrmBytes
e.lPtrToImage
How do I get at that array in memory and save it to disk? It seems to
suggest a pointer which is not supported in VB.

Hi,
I have a picturebox with graphics drawn from different objects. In one object I used
Pen P1;
P1 = new Pen(Color.Blue, 3);
Graphics g = null;
g = Graphics.FromImage(image.Image);
g.DrawPath(P1, Wirepath);

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

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...
