I keep trying to get myself out of the return-code mindset, but it
doesn't seem to work. They are suppose to get rid of if-then statements
of return codes, but you still have to do an if statement once the code
leaves your control (3rd party libraries, OS functions, etc) to throw
an exception?
Does anyone have any good suggestions on a book or website that deals
with exception handling that could help turn this poor mind off of

Approximately once a month, a client of ours sends us a bunch of
comma-delimited text files which I have to clean up and then import
into their MS SQL database. All last week, I was using a Cold Fusion
script to upload the cleaned up files and then import the records they
contained into the database, though obviously, the process took
friggin' forever, and could have been done 500x quicker had I done it
directly on the server. My SQL...

I am working on device that utilizes a Motorola 68HC16 microcontroller. I am
using an old unsupported piece of crap Whitesmith's / Intermetrics / Tasking
compiler. The embedded compiler business was quite insestual for while
wasn't it? I need to write putchar so that printf can function properly.
Anyway, the compiler comes with just a shell of a putchar routine. It
literally returns the character you passed to it and nothing else. That is...

we are trying to standardize return codes across our .NET
applications (that are soon to be developed.) What is the
best practice for standardizing return codes? I know of
only the following option.
Creating a class library that will contain the return
codes (which will be static strings). Calling the return
codes from this library across different applications.
Please let me know if you have implemented return codes in

hi! i have a Perl code in here that when ran the program accepts any Perl codes from the user input (<STDIN>, of course use no syntax errors), then after breaking the multiline input, the inputs will be part of the program codes and well executed simoultaneously after breaking the multiline input.
my novice codes as follows:

Hi,
I would like to have someone comments on what's the best practice
defining error codes in C.
Here's what I think:
solution A:
using enum
pros: type safe. better for debug (some debugger will show the name
not only the value)
cons: enum can not be forward declared which makes all error codes

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:

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 am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
