When throwing exceptions, I often pass in a formatted string that exposes details about the problem that has occurred. I always specify a formatting provider if possible (which is good practice because otherwise you may forget to decide which culture is appropriate and as the default is the current culture, that can lead to many bugs). ...
Is there a way to automatically catch all (unchecked) exceptions thrown by BlazeDS remoting methods, without wrapping each one in a last-resort try/catch block? My code catches any checked exceptions as required, but I'd prefer that stray NullPointerExceptions, ArrayIndexOutOfBoundsExceptions and the like don't end up being set to the cl...

The relevant code in that method is as follows: if (pItem->mask && LVIF_TEXT) { switch(pItem->iSubItem) { case 0: lstrcpy(pItem->pszText, rLabel.m_strText); ...

What is the general rule of thumb when deciding whether to add a throws clause to a method or using a try-catch? From what I've read myself, the throws should be used when the caller has broken their end of the contract (passed object) and the try-catch should be used when an exception takes place during an operation that is being carri...

Iterating a block in Ruby is simple enough - it finishes cleanly and proceeds on to the rest of the code. Iterating with an Enumerator, on the other hand, is a bit more confusing. If you call :each without a block, an Enumerator is returned instead. :next can then be called on the Enumerator to get each next iterative value. And then...
I know that this would be bad practice although I know that I would not be able to explain why. int [] intArr = ... ... try{ int i = 0; while(true){ System.out.println(intArr[i++]); } }catch(ArrayIndexOutOfBoundsException e){} I think that you are only supposed to use exceptions for things that shouldn't happen. I am...
I understand (now) that Response.Redirect() and Response.End() throw a ThreadAbortException as an expensive way of killing the current processing thread to emulate the behaviour of ASP Classic's Response.End() and Response.Redirect methods. However. It seems intermittently in our application that the exception bubbles too high. For exa...
