It wasn't flagging the situation that I thought was the problem, but calling his colleagues b******s in a message that would be displayed to the users.
By all means write it to an internal log file or something, but don't swear at the users, it's not very professional.

Color me stupid, I thought the b*****s was the person's name. Note, my initials are B.S. In my case, the manager's name was put into the message replacing the b******s.
Now that i understand your true meaning...
I have a client who is paying top price for a website face lift. I was doing an A/B compare on the test release of the site in FireFox and IE. I must admit they did a good job with absolutely no difference between the two browsers. Curious as a cat, I decided to view the source code in hopes of getting the link to their Java Script file and any style sheets for future reference. Paging down in the source i found a hidden DIV where a developer left a large does of his explicitive filled comments regarding the client. HOLY-COW! I couldn't believe what i was reading, and can't repeat any of it here.
Regardless, it's all pretty funny stuff.

...so read an error message I found in a customer's code a while back. 
Needless to say it didn't last long once I found it!

I found a TODO: handle string thingie in some code the other day..until today I STILL don't know what the author ment to say 
To reassure you, I long promoted that function to the recycle bin.

Not only a memory issue (using string instead of stringbuilder), but why have the gods^W BCL group created the string.PadRight(lenth, ' ') method?
What do you think?

I would think someone is learning C#.
I can see me making mistakes of exactly the same type.
Ok, I know about stringbuilder, but there are whole top-level namespaces I never used. I certainly do not know their functions by heart.
Failure is not an option - it's built right in.

My colleague and I had an interesting discussion about this. According to us, there are two types of programmers out there. The first type thinks 'This is such a common thing to do, someone MUST have included it' and therefor ends up using the PadString method. The second type just churns away without seconds thoughts and ends up with the originally posted code.
The funny thing is that 9 out of 10 times people tend to refactor these snippits into a utilities class, calling the method 'PadString'

...so lets make it global.
This was the answer of a "Technical Consultant" that I worked with many years ago. All of his loops were for i = 1 to 10 next i. This was VB 3 - so some time ago!
To save himself the effort of dim i as integer at the beginning of every function he wanted to use "i" he just made it a global. I can't blame him too much - he was a COBOL programmer who had made the leap to VB.
It made for some surprisingly subtle bugs! Needless to say that I removed it after having to try quite hard to show him the benefits (I was a junior C++ programmer at the time).

We must have worked with the same guy! I once worked on a VB program with a couple of hundred global variables. When i complained to the original developer he said, "What's wrong with that?"
Funny, this guy was an author of multiple VB books.

many years ago I saw the same years ago in a FORTRAN prog, as you say some of the bugs this introduced were interesting. Perhaps this guy used to work in England?

Hello, love the show, long time listener, first time caller.
One of the company's c++ coding guidelines is that goto's are forbidden. For some developers who use goto statements as error handling this could present a problem. For others, ...
for ( ;; ) {
for ( ;; ) {
bool someError = func();
if (someError) {
break;
}
if (anotherError) {
break;
}
break;
}
for ( ;; ) {
break;
}
break;
}
After stumbling upon this beauty I searched and found over 200 infinite loops used as an error handling technique. Not one of these loops ever actually looped.

Yep, seen it. I hate this irrational ban on goto. It's out of date - it dates from a time when decent control structures weren't common. A judicious, careful, occasional use of a goto is fine. Subverting a control structure to give it a different meaning is definitely not.

Goto's are really really bad and should be super rarely used. They are not needed for error handling. The only good use I've seen for goto's is machine generated code with tools like YACC and LEX.
Generally speaking, break, continue, and multiple returns can cause problems too. Readability and maintainability are very important.
Imagine if you will a "come from" statement. You put a label X somewhere then in a totally different part of the method you place a "come from" label X. Whenever control reaches the label you goto the "come from". Imagine how hard it would be to read that code.
What's wrong with using exceptions for error handling?

This
if (spin_trylock(&tty_lock.lock))
goto got_lock;
if (tsk == tty_lock.lock_owner) {
WARN_ON(!tty_lock.lock_count);
tty_lock.lock_count++;
return flags;
}
spin_lock(&tty_lock.lock);
got_lock:
WARN_ON(tty_lock.lock_owner);seems pretty well justified for me.
You could do this with nested ifs, but you would neither get more clarity nor faster code. Only code indenting out at your right screen margin.

I guess we could argue this back and forth. It comes down to avoiding mistakes and doing things as a matter of policy.
E.g.
I never do this:
int* y, z;
I always do this:
int* y;
int z;
Why you ask. Too easy to read it wrong at a glance, too easy to miss something. Some logic as to why I never use goto's and why I don't put returns anywhere but at the very bottom or very top of a function.
I believe this to be more than just a matter of style.

That is an excellent paper! I rarely use goto, but sometimes it is the best solution to a problem. (Example: escaping from multiple nested loops.)
I once read someone’s general rule that you always go forward, but I found one exception years ago:
NEXT_BYTE:
if( x>xmin ) {
Byte = *(--vptr);
if( Byte == 0xFF ) {
x -= 8;
goto NEXT_BYTE;
}
}
Sure the above code could be written using a loop and originally was, but this increased the speed (graphics code) enough to justify its use at the time.

I once came across an Access database (already WTF) that used columns instead of rows for a Calendar like application ! The Calendar table had (from memory) 1 row for each day with 50+ columns for each half hour block from 8:00am. Now you can imagine the horror it was to try to maintain such an application. The reports that ran of this dog were nightmarish, even to SELECT a single day that had 'something' happening on it looked something like
SELECT * FROM Calendar WHERE Time800 <> '' OR Time830 <> '' OR Time900 <> '' .. OR Time1600 <> ''
I can imagine what the coder would have said when asked to make the days start a little earlier than 8:00, "Oh, sure, that'll take at least another 4 months to re-schema the database and touch up all the affected queries".
And when the original developers were sacked for taking way took long and we took over the project we were questioned why we were completely rewriting it from scratch. The above Calendar table was just one example in this diseased rats nest, there were plenty of others like using hidden form controls as global variables. You would open up the main form and had absolutely no hope of actually telling what it would look like when run since it was completely covered in these demons from hell. I just hate with a passion code that does not read simple, I hate it when I cannot confidently make a simple change to some code without it screwing up something completely unrelated because the variable I modded was global and had different meanings depending on where it was called from.
Anyway that's my rant 
Code should be simple. No excuses.

More than 50 half hours after 8am? Which planet was that calendar designed for - mercury or venus?!?

I wager the developers put in extra hours for leap years.

This jewel is one of my favourites. I found it in a customer's code (they asked us to enhance the application):
BOOL cIBatchDownload::OnInitDialog()
{
if (m_bCreated)
{
}
...
return TRUE;
}
I eager to look deeper into this code to find more post for this newly created forum. ![Badger | [badger,badger,badger,badger...]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/badger.gif)

Hmmm!
I have done that when outlining the code before filling the in-betweens. The real question is: what was supposed to be inserted there?

Once upon a time, I was leading a team that was doing the server side of an internet banking application. Because this sort of app was in its infancy, there was little confidence, and a lot of paranoia. IIRC, the flow was that a connection would come into an external server, a session would be created and packed and sent across a serial cable to the machine that would handle authentication. This packet would be decrypted, verified and sent back, then it would move on to another machine across another serial cable for the transaction. We had essentially the same process running on each machine, but operating a bit differently depending on the role.
ANYWAY ... we had a problem in that sometimes, a session would drop out, and the service would crash. We logged, we debugged, we stepped through, and couldn't find it, until one fine day, we hit a breakpoint, and the developer said "Huh. That's funny. That should be a session object, not a data chunk."
The penny dropped. "Ah," I said. "That session ID that you're passing back and forth between machines ... is that an index into the session array, or what?"
"No," came the bemused reply. "I thought it would be quicker to just use the address of the object".
Apparently, the original object had been deleted because the session had been dropped, and the runtime had reused the space for something else. So when the session ID was cast from its session ID form (int) to its pointer form, it was pointing at something else. Don't get me wrong ... I love pointers. I just had no idea that their abuse would be extended to neighbouring machines.
