  • Determine Last Modification Datetime for an Azure Table

    - by embeddedprogrammer
    I am developing an application which may be hosted on a microsoft sql server, or on Azure SQL, depending upon the end user's wishes. My whole system works fine with the exception of some WCF functions which determine the last modification time of tables using the following technique: SELECT OBJECT_NAME(OBJECT_ID) as tableName, last_user_update as lastUpdate FROM mydb.sys.dm_db_index_usage_stats This query fails in Azure. Is there any analogous way to get table last modification dates from Azure's sql?

  • Replace an Array with an Array

    - by Dane Man
    I have and NSMutableArray and I want to replace it with another, but if I try to do it like this... firstArray = secondArray; ...then it seems to erase the entire firstArray and I get this error message.. Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)' ...and the bounds should be (6) not (0). Is there a correct way to replace the array? PS: I already checked the secondArray and it functions fine.

  • Rails Testing Question

    - by Steve
    Hi, I am trying to test a functionality, which inserts few details into the DB. In the test.log, it shows the insert command that is generated and also the log messages that I have placed to show the progress and everything seems to be working fine except the actual data is not getting inserted into the DB. I am checking whether data is inserted in db/test.sqlite3. No exception is generated when the test cases are run. Is there a setting, which I have to set inorder to insert data into the test DB? or am i missing anything else Thanks

  • How can I pipe input to a Java app with Perl?

    - by user319479
    I need to write a Perl script that pipes input into a Java program. This is related to this, but that didn't help me. My issue is that the Java app doesn't get the print statements until I close the handle. What I found online was that $| needs to be set to something greater than 0, in which case newline characters will flush the buffer. This still doesn't work. This is the script: #! /usr/bin/perl -w use strict; use File::Basename; $|=1; open(TP, "| java -jar test.jar") or die "fail"; sleep(2); print TP "this is test 1\n"; print TP "this is test 2\n"; print "tests printed, waiting 5s\n"; sleep(5); print "wait over. closing handle...\n"; close TP; print "closed.\n"; print "sleeping for 5s...\n"; sleep(5); print "script finished!\n"; exit And here is a sample Java app: import java.util.Scanner; public class test{ public static void main( String[] args ){ Scanner sc = new Scanner( System.in ); int crashcount = 0; while( true ){ try{ String input = sc.nextLine(); System.out.println( ":: INPUT: " + input ); if( "bananas".equals(input) ){ break; } } catch( Exception e ){ System.out.println( ":: EXCEPTION: " + e.toString() ); crashcount++; if( crashcount == 5 ){ System.out.println( ":: Looks like stdin is broke" ); break; } } } System.out.println( ":: IT'S OVER!" ); return; } } The Java app should respond to receiving the test prints immediately, but it doesn't until the close statement in the Perl script. What am I doing wrong? Note: the fix can only be in the Perl script. The Java app can't be changed. Also, File::Basename is there because I'm using it in the real script.

  • Should you always write code for else cases that "can never happen"?

    - by johnswamps
    Take some code like if (person.IsMale()) { doGuyStuff(); } else { doGirlOtherStuff(); } (Yes, I realize this is bad OO code, it's an example) Should this be written so that to explicitly check if person.isFemale(), and then add a new else that throws an exception? Or maybe you're checking values in an enum, or something like that. You think that no one will add new elements to the enum, but who knows? "Can never happen" sounds like famous last words.

  • C# some sort of plugin system

    - by nLL
    Hi, I am a mobile web developer and trying to monetize my traffic with mobile ad services and i have a problem. First of all to get most of out of your ads you usually need to do server side request to advert company's servers and there are quite few ad services. Problem starts when you want to use them in one site. All have different approaches to server side calls and trying to maintain and implement those ad codes becomes pain after a while. So I decided to write a class system where i can simply create methods for every company and upload it to my site. So far i have public Advert class public AdPublisher class with GetAd method that returns an Advert public Adservice class that has Service names as enum I also have converted server request codes of all ad services i use to classes. It works ok but I want to be able to create an ad service class upload it so that asp.net app can import/recognize it automatically like a plugin system. As I am new to .net I have no idea where to start or how to do it. To make thing clear here are my classes namespace Mobile.Publisher { public class AdPublisher { public AdPublisher() { IsTest = false; } public bool IsTest { get; set; } public HttpRequest CurrentVisitorRequestInfo { get; set; } public Advert GetAd(AdService service) { Advert returnAd = new Advert(); returnAd.Success = true; if (this.CurrentVisitorRequestInfo == null) { throw new Exception("CurrentVisitorRequestInfo for AdPublisher not set!"); } if (service == null) { throw new Exception("AdService not set!"); } if (service.ServiceName == AdServices.Admob) { returnAd.ReturnedAd = AdmobAds("000000"); } return returnAd; } } public enum AdServices { Admob, ServiceB, ServiceC } public class Advert { public bool Success { get; set; } public string ReturnedAd { get; set; } } public partial class AdService { public AdServices ServiceName { get; set; } public string PublisherOrSiteId { get; set; } public string ZoneOrChannelId { get; set; } } private string AdmobAds(string publisherid) { //snip return "test" } } Basically i want to be able to add another ad service and code like private string AdmobAds(string publisherid){ } So that it can be imported and recognised as ad service. I hope i was clear enough

  • Can I write a test without any assert in it ?

    - by stratwine
    Hi, I'd like to know if it is "ok" to write a test without any "assert" in it. So the test would fail only when an exception / error has occured. Eg: like a test which has a simple select query, to ensure that the database configuration is right. So when I change some db-configuration, I re-run this test and check if the configuration is right. ? Thanks!

  • How can I forcibly close a TcpListener

    - by Nissim
    I have a service which communicates through tcpListener. Problem is when the user restarts the service - an "Address already in use" exception is thrown, and the service cannot be started for a couple of minutes or so. Is there's any way of telling the system to terminate the old connection so I can open a new one? (I can't just use random ports because there is no way for the service to notify the clients what is the port, so we must depend on a predefined port)

  • Exceptions confusion

    - by Misiur
    Hi there. I'm trying to build site using OOP in PHP. Everyone is talking about Singleton, hermetization, MVC, and using exceptions. So I've tried to do it like this: Class building whole site: class Core { public $is_core; public $theme; private $db; public $language; private $info; static private $instance; public function __construct($lang = 'eng', $theme = 'default') { if(!self::$instance) { try { $this->db = new sdb(DB_TYPE.':host='.DB_HOST.';dbname='.DB_NAME, DB_USER, DB_PASS); } catch(PDOException $e) { throw new CoreException($e->getMessage()); } try { $this->language = new Language($lang); } catch(LangException $e) { throw new CoreException($e->getMessage()); } try { $this->theme = new Theme($theme); } catch(ThemeException $e) { throw new CoreException($e->getMessage()); } } return self::$instance; } public function getSite($what) { return $this->language->getLang(); } private function __clone() { } } Class managing themes class Theme { private $theme; public function __construct($name = 'default') { if(!is_dir("themes/$name")) { throw new ThemeException("Unable to load theme $name"); } else { $this->theme = $name; } } public function getTheme() { return $this->theme; } public function display($part) { if(!is_file("themes/$this->theme/$part.php")) { throw new ThemeException("Unable to load theme part: themes/$this->theme/$part.php"); } else { return 'So far so good'; } } } And usage: error_reporting(E_ALL); require_once('config.php'); require_once('functions.php'); try { $core = new Core(); } catch(CoreException $e) { echo 'Core Exception: '.$e->getMessage(); } echo $core->theme->getTheme(); echo "<br />"; echo $core->language->getLang(); try { $core->theme->display('footer'); } catch(ThemeException $e) { echo $e->getMessage(); } I don't like those exception handlers - i don't want to catch them like some pokemons... I want to use things simple: $core-theme-display('footer'); And if something is wrong, and debug mode is enabled, then aplication show error. What should i do?
