The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

Re: Expletive Deleted Rob Grainger10-Jul-13 5:14 Rob Grainger 10-Jul-13 5:14  There are two parts: 1. We now use a .config file to store these settings. Reading these is done during app startup. If errors occur, either (a) a message is shown to the user if the settings is required, or (b) an entry is made in a log if the entry is non-critical. 2. The original coding loaded the settings within a VB Form. I've migrated this to app startup code, so the errors (a) raise an exception so they can be reported back to the user in a more managed way. The old app has the business logic entirely in VB forms, in the new version almost all business logic is in C# classes, the (WPF) forms have minimal code to set the data context for the form to an appropriate view model object.

I know one wizard of Oz who writes batch mode applications (each averages 30 mins of run time) and over years, he has evolved this beeps thingy into the state of art. Most days, his daily task comprises of starting the comps, setting batch jobs, set them running and then loiter around in office all day. He can be at other end of room and just by hearing meaningless (to me) sequence of beeps, he can tell which batch job which started finished. For those not directly involved with his work, it is a sight to see whenever his batch jobs fail and he gets desk-bound for hours. Guess where the beeps are coming from in those days? His mouth!!

I had a look into it and, ignoring the fact that there would probably not be an internal speaker, a modern Windows O/S will divert the beep to the soundcard if there is one (even if its integrated) which needs speakers. So unless you have a machine with an internal speaker running Windows 98 or something, it just won’t do anything. For some reason that made me feel sad and I briefly missed not being able to make things beep in such a simple manner!

Re: Expletive Deleted RafagaX11-Jul-13 4:43 RafagaX 11-Jul-13 4:43  The developer who made this, should be forced to wear headphones and make his/her program fail constantly for 24 hours... Seriously, there was a time when computers had an internal speaker, given that this is VB6, i'm not really surprised. CEO at: - Rafaga Systems - Para Facturas - Modern Components for the moment...

I don't think that's what he meant though. A bit pedantic, I'm sorry. Re: What this 'null' check doing here... KP Lee10-Jul-13 19:52 KP Lee 10-Jul-13 19:52  I think the point was that C# List<Employee> employees = GetEmployees(); could just as well have been used to create a null or non-null employees object because the if statement would never be false for a statement that could produce a null result. In fact you might want to execute C# if (employees == null) throw... after executing the above line because now you are in a situation where the if statement could be true or false even if the current coding of the routine would never return null.
