Hi, I am new to windows api programming and I wanted to create a little
utility program for myself in c using the mini gw compiler. I bought
petzold's book, programming windows 5th edition. I know the book was
written for people using visual c++ 6, win98/NT before xp came along but
thought it would be ok. My problem is that having lifted an example of code
in the GetPrinterDC function(pasted below) the compiler seems to take
exception...

Hi there,
I am working on an application to be used in our local Forensics
department...
Among other things the app will connect to a digital camera and download the
images to the hard drive. For various reasons I need to be able to say with
certainty that the image on the hard drive is exactly what was on the
camera... any ideas on best way to achieve this...?

As far as I know, Perl is known as "there are many ways to do
something" and Python is known as "there is only one way". Could you
please explain this? How is this possible and is it *really* a good
concept?

Hi All I was just wondering if there was a better function/way to get
information on all the printers currently installed than EnumPrinters.
I only really need all the printer names but don't care to do the
memory management involved with EnumPrinters.
I looked at using GetProfileString with but that requires I
know the buffer size ahead of time.
Any alternatives would be appreciated

they just know to program in C or C is better for that kind of

I am new to vb.net (I am an old vb6 programmer). I cannot figure out
an easy way to watch variables. In vb6 all I did was right click and
could chose to stop execution when a variable chances as well as how
extensive a "universe" (context) I want it to watch. In .net I must
work in debug mode but I do not see how to stop execution when a
variable changes nor controlling how brad a context I wish to watch.
Any help would be appreciated

Hello World,
I am trying to get all the shared printers for a remote Windows 2003 server
using the EnumPrinters function and keep getting an error returned that
corresponds to the message: "The filename, directory name, or volume label
syntax is incorrect". I've tried hard-coding a value of a valid server in the
form \\hcr591plotpa001 (and tried it without the \\) but it doesn't seem to
make a difference.
My code looks like 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

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...
