Difference between a C++ exception and Structured Exception
You actually have three mechanisms: C++ exceptions, implemented by the compiler (try/catch) Structured Exception Handling (SEH), provided by Windows (__try / __except) MFC exception macros (TRY, CATCH – built on top of SEH / C++ exceptions – see also TheUndeadFish’s comment) C++ exceptions usually guarantee automatic cleanup during stack unwinding (i.e. destructors of local objects … Read more
Best practice for error handling with ASP.NET Web API
Error handling in Web API is considered a cross-cutting concern and should be placed somewhere else in the pipeline so the developers doesn’t need to focus on cross-cutting concerns. You should take a read of Exception Handling in ASP.NET Web API What happens if a Web API controller throws an uncaught exception? By default, most … Read more
Detecting what the target object is when NullReferenceException is thrown
At the point where the NRE is thrown, there is no target object — that’s the point of the exception. The most you can hope for is to trap the file and line number where the exception occurred. If you’re having problems identifying which object reference is causing the problem, then you might want to … Read more
Finding the cause of System.AccessViolationException
What you are experiencing is the exact equivalent to “The program has experienced a problem and will now close”, except it’s being caught by the .NET runtime, rather than the OS. Looking at the stack trace, it’s not being triggered by your code, which makes me think that it’s coming from a worker thread spawned … Read more
Try-catch-finally and then again a try catch
Write a SQLUtils class that contains static closeQuietly methods that catch and log such exceptions, then use as appropriate. You’ll end up with something that reads like this: public class SQLUtils { private static Log log = LogFactory.getLog(SQLUtils.class); public static void closeQuietly(Connection connection) { try { if (connection != null) { connection.close(); } } catch … Read more
Throwing exceptions in callback method for Timers
The exception is not passed back to the calling thread. If you want it to be, you can add a catch block and figure out a way to signal the calling thread. If the calling thread is a WinForms or WPF UI thread, you can use the SynchronizationContext class to pass a call to the … Read more
How do I write the exception from printStackTrace() into a text file in Java?
It accepts a PrintStream as a parameter; see the documentation. File file = new File(“test.log”); PrintStream ps = new PrintStream(file); try { // something } catch (Exception ex) { ex.printStackTrace(ps); } ps.close(); See also Difference between printStackTrace() and toString()
raise statement on a conditional expression
If you absolutely want to raise in an expression, you could do def raiser(ex): raise ex return <value> if <bool> else raiser(<exception>) This “tries” to return the return value of raiser(), which would be None, if there was no unconditional raise in the function.
Catching exception in context manager __enter__()
Like this: import sys class Context(object): def __enter__(self): try: raise Exception(“Oops in __enter__”) except: # Swallow exception if __exit__ returns a True value if self.__exit__(*sys.exc_info()): pass else: raise def __exit__(self, e_typ, e_val, trcbak): print “Now it’s running” with Context(): pass To let the program continue on its merry way without executing the context block you … Read more
