问题 I'm using selectors to dynamically call functions in Objective-C. My problem is that my @try / @catch block is not catching the exception if I pass an non-existent function name. In the console I get an uncaught NSInvalidArgumentException and further down I get an uncaught NSException . I have tried catching the the two types of exceptions in a standard @try / @catch block but they aren't registering. Xcode won't let me compile if I try to catch NSInvalidArgumentException as it's not a

问题 Edit: Ignore this, I figured it out about 3 seconds after posting this but can't delete it =( I have this try, except code for working with RackSpace cloudfiles try: cacheobject = cachecontainer.get_object('file.jpg') except NoSuchObject as objectname: raise tornado.web.HTTPError(404) If 'file.jpg' is not found, the exception 'NoSuchObject' is raised.

问题 A method performs a recursive scan for yaml files and parses them, extracts some of the information. I use sfYamlParser to parse the yaml. I enclosed the call to parse() in a try block and catch "Exception $e" but I still get a "Fatal Error: uncaught exception. try{ $definition = $parser->parse(file_get_contents($filePath));//line 20 } catch(Exception $e) { throw new Exception("Parsing model definiion '$filePath' failed.", 0, $e); } Snippet from stack trace: ...Indexer.php(20): sfYamlParser-

However, none of the other exceptions from within the thread loop are caught, like this one - its stack trace is: System.ComponentModel.ReflectPropertyDescriptor

问题 I have a Powershell script that inserts a primary key value and another value into a SQL Server 2012 database. This is the INSERT SQL string that includes IF NOT EXISTS , where $sql_output is an int $SQL_UPDATE = "BEGIN IF NOT EXISTS (SELECT CONVERT(VARCHAR(12), GETDATE(), 107) as Date_to_Display FROM dbo.Download WHERE dbo.Download.Date_of_Download = GETDATE()) BEGIN INSERT INTO dbo.Download VALUES (convert(date, GETDATE(), 100),$sql_output) END END" And this is the code that attempts to

问题 I have a given class with some methods in it, one of which throws an exception as per the following when certain faulty criteria is met: PHP if ($this->mode !== null) { throw new LogicException('Nem kezdhető új "insert" utasítás.'); } If I do not handle this error, PHP will show the "Fatal Error" message as expected, but not the custom message that was passed into the first parameter of the constructor of LogicException : Fatal error : in /home/uxxxxxxxxx/public_html/test.php on line 87 I
