  • c# order preserving data structures

    - by Oren Mazor
    Oddly enough, MSDN has no information on the order preserving properties of data structures. So I've been making the assumption that: Hashtable and Hashset do not preserve the insertion order (aka the "hash" in there is a giveaway) Dictionary and List DO preserve the insertion order. from this I extrapolate that if I have a Dictionary<double,double> foo that defines a curve, foo.Keys.ToList() and foo.Values.ToList() will give me an ordered list of the scope and domain of that curve without messing about with it?

  • Problem running a simple EJB application

    - by Spi1988
    I am currently running a simple EJB application using a stateless Session Bean. I am working on NetBeans 6.8 with Personal Glassfish 3.0 and I have installed on my system both the Java EE and the Java SE. I don't know whether it is relevent but I am running Windows7 64-bit version. The Session Bean I implemented has just one method sayHello(); which just prints hello on the screen. When I try to run the application I'm getting the following error: pre-init: init-private: init-userdir: init-user: init-project: do-init: post-init: init-check: init: deps-jar: deps-j2ee-archive: MyEnterprise-app-client.init: MyEnterprise-ejb.init: MyEnterprise-ejb.deps-jar: MyEnterprise-ejb.compile: MyEnterprise-ejb.library-inclusion-in-manifest: MyEnterprise-ejb.dist-ear: MyEnterprise-app-client.deps-jar: MyEnterprise-app-client.compile: MyEnterprise-app-client.library-inclusion-in-manifest: MyEnterprise-app-client.dist-ear: MyEnterprise-ejb.init: MyEnterprise-ejb.deps-jar: MyEnterprise-ejb.compile: MyEnterprise-ejb.library-inclusion-in-manifest: MyEnterprise-ejb.dist-ear: pre-pre-compile: pre-compile: do-compile: post-compile: compile: pre-dist: post-dist: dist-directory-deploy: pre-run-deploy: Starting Personal GlassFish v3 Domain Personal GlassFish v3 Domain is running.

  • Schema qualified tables with SQLAlchemy, SQLite and Postgresql?

    - by Chris Reid
    I have a Pylons project and a SQLAlchemy model that implements schema qualified tables: class Hockey(Base): __tablename__ = "hockey" __table_args__ = {'schema':'winter'} hockey_id = sa.Column(sa.types.Integer, sa.Sequence('score_id_seq', optional=True), primary_key=True) baseball_id = sa.Column(sa.types.Integer, sa.ForeignKey('summer.baseball.baseball_id')) This code works great with Postgresql but fails when using SQLite on table and foreign key names (due to SQLite's lack of schema support) sqlalchemy.exc.OperationalError: (OperationalError) unknown database "winter" 'PRAGMA "winter".table_info("hockey")' () I'd like to continue using SQLite for dev and testing. Is there a way of have this fail gracefully on SQLite?

  • Configure Apache to use different Unix User Accounts (www-data) per Site.

    - by BrainCore
    An Apache 2.x Webserver with default configurations from the ubuntu/debian repositories will use the www-data unix account for apache2 processes handling web requests. Assuming that apache is serving two different sites (domain1.com and domain2.com), is it possible for apache to use unix user www-data1 when handling requests to domain1.com, and use unix user www-data2 when handling requests to domain2.com? The motivation is to isolate the code for each domain name from one another.

  • How can I setup a simple custom route using Zend Framework's Zend_Application?

    - by Billy ONeal
    I'm looking to setup a custom route which supplies implicit parameter names to a Zend_Application. Essentially, I have an incoming URL which looks like this: /StandardSystems/Dell/LatitudeE6500 I'd like that to be mapped to the StandardsystemsController, and I'd like that controller to be passed parameters "make" => "Dell" and "model" => "LatitudeE6500". How can I setup such a system using Zend_Application?

  • Connect to ArcGIS Server w/ ArcCatalog

    - by nw
    How does one add a workstation account to the agsadmin group on the server? Does this require both machines to be on the same Windows domain? A colleague cannot connect via ArcCatalog but I don't know how to add his account to the group because the account does not exist on the server. (Oddly I can connect from my machine, but my account is also not a member of the agsadmin group.)

  • Refer to similar associated models with a common name

    - by Horace Loeb
    I have these models: class Bill < ActiveRecord::Base has_many :calls has_many :text_messages end class Call < ActiveRecord::Base belongs_to :bill end class TextMessage < ActiveRecord::Base belongs_to :bill end Now, in my domain calls and text messages are both "the same kind of thing" -- i.e., they're both "bill items". So I'd like some_bill.bill_items to return all calls and text messages associated with that bill. What's the best way to do this?

  • Generate CSV file from rails

    - by Elliot
    I've been reading similar questions, but many of the answers are outdated or not clear enough for me. I'd like to be able to just do something like (in a controller action): respond_to do |format| format.html format.csv end I know I'd then need a view such as action.csv.erb So my questions are: 1) What do I need to configure in rails to allow this to happen in general. 2) How should I setup the CSV view to display some basic fields from a model?

  • Can I retain a Google apps session token permanently for a specific user who logs into my google app

    - by Ali
    Hi guys, is it possible to retain upon authorization a single session token for a user who signs into my gogle application. CUrrently my application seems to every now and then require the user to authenticate into google apps. I think it has to do with session dying out or so. I have the following code: function getCurrentUrl() { global $_SERVER; $php_request_uri = htmlentities(substr($_SERVER['REQUEST_URI'], 0, strcspn($_SERVER['REQUEST_URI'], "\n\r")), ENT_QUOTES); if (isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) == 'on') { $protocol = 'https://'; } else { $protocol = 'http://'; } $host = $_SERVER['HTTP_HOST']; if ($_SERVER['SERVER_PORT'] != '' && (($protocol == 'http://' && $_SERVER['SERVER_PORT'] != '80') || ($protocol == 'https://' && $_SERVER['SERVER_PORT'] != '443'))) { $port = ':' . $_SERVER['SERVER_PORT']; } else { $port = ''; } return $protocol . $host . $port . $php_request_uri; } function getAuthSubUrl($n=false) { $next = $n?$n:getCurrentUrl(); $scope = 'http://docs.google.com/feeds/documents https://www.google.com/calendar/feeds/ https://spreadsheets.google.com/feeds/ https://www.google.com/m8/feeds/ https://mail.google.com/mail/feed/atom/'; $secure = false; $session = true; //echo Zend_Gdata_AuthSub::getAuthSubTokenUri($next, $scope, $secure, $session);; return Zend_Gdata_AuthSub::getAuthSubTokenUri($next, $scope, $secure, $session).(isset($_SESSION['domain'])?'&hd='.$_SESSION['domain']:''); } function _regenerate_token() { global $BASE_URL; if(!$_SESSION['token']) { if(isset($_GET['token'])): $_SESSION['token'] = Zend_Gdata_AuthSub::getAuthSubSessionToken($_GET['token']); return; else: _regenerate_sessions(); _redirect(getAuthSubUrl($BASE_URL . '/index.php?'.$_SERVER['QUERY_STRING'])); endif; } } _regenerate_token(); I know I'm doing it all wrong here and I don't know why :( I have a CONSUMER SECRET code but only use it whereever I need to access a google service. However something is wrong with my authentication as the user has to periodically 'grant access to my application' and reauthorise himself... help please
