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.

If something totally unexpected happens (like e.g. the 'ObjectDisposed' you mentioned), there should be a general top level exception handler at the application level, but for sure such an exception must never be swallowed silently by the executing code. Not in a million years, in no circumstance whatsoever!

That depends what one is trying to do. Would people like Visual Studio very much if it died any time an exception occurred while evaluating expressions in the Watch window? Or is the proper action to show the problematic expression with an indication that it cannot be evaluated?

If a program is supposed to graph a function, it may at times be unclear the best way to handle an exception. If one is trying to graph an expression like f(x)=1/x, it's best that the problematic case at x=0 be swallowed, while graphing is allowed to continue on the other side. On the other hand, if the function is one which will always throw an exception, calling the function 1,000 times while drawing the graph will cause 1,000 exceptions to be thrown.

Swallowing exceptions in a fashion that hides any indication of what type of exception occurred seems like a bad idea, but it would seem there are many situations where a calling application is merely interested in whether or not an operation worked, and not what went wrong if it didn't.
