Whithin the test everything works great except the date, I mean, I can get the varchar fields but the DATE field (called R_DATE) is impossible.

I'm a novice Android programmer, and to help me understand how Intents really work, I wanted to put together a small Activity which would let the user call startActivity() with any action and data they want.

I have a very basic upload action in my controller. It looks something like the action below. It works great. The only problem I'm seeing is when a user cancels an upload (or hits stop on their browser). I am able to recover correctly, but not before seeing an uncaught exception in my logs. The exception is listed below. Any help o...
I was under the impression that using setjmp() and longjmp() in C++ was almost guaranteed to mess up the stack, since these functions don't perform unwinding like, say, exceptions do. This MSDN page, however, indicates that the Microsoft implementation can be told to invoke the destructors of local objects, which implies that careful use...

Hi. I've read pretty often, that using try-catch is quite slow compared to normal code. Now I wonder if the number of caught exceptions affects the performance of the code or not. So is try{ ... } catch(StrangeException e){ ... } slower than try{ ... } catch(StrangeException e){ ... } catch(MysteriousException e){ ... } c...
Does anybody know how ASP.NET loads code snippet (i.e. the code you write including comments) on exception and displays it to user. It is the error screen with code snippet in yellow where the line where the occurs is highlighted in red. ...
As an exercise, I've been trying out various ways of generating all permutations of a list in Python -- recursive, non-recursive... -- and comparing the performance with itertools.permutations(). But I'm having trouble with the generator version of the recursive method, which doesn't finish cleanly with a StopIteration exception, but ins...

I feel like I'm missing something very simple here. I have Eclipse set up to break on all exceptions. So, let's say that it breaks on an AssertationFailedException. The Debug window will show that thread suspended and has the following data: Thread [Thread-1] (Suspended (exception AssertionFailedException)) ContactManager.addCon...

I'm Java beginner, but I thought that when using try-catch-finally I don't have to declare the exception using throws SQLException. However if I don't use it the compiler gives me the error: "unreported exception java.sql.SQLException; must be caught or declare to be thrown". I included a catch so I'm not sure why this errors occurs. pu...
