  • Why is the 'if' statement considered evil?

    - by Vadim
    I just came from Simple Design and Testing Conference. In one of the session we were talking about evil keywords in programming languages. Corey Haines, who proposed the subject, was convinced that if statement is absolute evil. His alternative was to create functions with predicates. Can you please explain to me why if is evil. I understand that you can write very ugly code abusing if. But I don't believe that it's that bad.

  • Basic date/time manipulation in NHiberate query

    - by Yann Trevin
    I'm trying to restrict my NHibernate query with some basic date/time manipulation. More specifically, I want to execute the following statement (pseudo-SQL): select * from article where created_on + lifespan >= sysdate with: created_on is mapped to a property of type DateTime. lifespan is mapped to a property of type TimeSpan. sysdate is the current date/time (of the database server or ofthe application host, I don't care) Is there any built-in way to do that by using the Criteria-API or HQL? return session .CreateCriteria<Article>() .Add( ? ) .List<Article>();

  • Embed remote desktop in browser

    - by Shaun_web
    I would like to embed a Remote Desktop session within my browser. I must use remote desktop because my clients can't install any additional software on the server. Here are some problems that I can already foresee: 1) I believe that I can embed an RDP ActiveX control, but then all I could support is IE. And even then, IE lockdown may forbid ActiveX controls. 2) I don't know anything about Apple computers, but I presume that they don't inherently run RDP? 3) I think there are ways to run RDP through a Java control. I don't have experience to know if this is a good or bad idea. I suppose that Java may even be disabled on some browsers, but don't know if this is a common case? So, what options have I got here to make this work reliably? I presume that I may need some default options (ie ActiveX), and then some fallback options (ie Java), and code to identify the correct option each time.

  • How to generate a random alpha-numeric string in Java

    - by Todd
    I've been looking for a simple java algorithm to generate a pseudo-random alpha-numeric string. In my situation it would be used as a unique session/key identifier that would "likely" be unique over 500K+ generation (my needs don't really require anything much more sophisticated) . Ideally I would be able to specify a length depending on my uniqueness needs. For example, a generated string of length 12 might look something like "AEYGF7K0DM1X". Answers: I like @Apocalisp and @erickson's answers equally well. The only downside to @Apocalisp's answer is it requires an apache class. Thanks to both for the help!

  • Where to maintain common information, that could be accessed by all forms

    - by The King
    Hi All, This is my first winform app in .NET... I have made a couple of ASP.NET app... In this app, I have some common variables, like current user name, his selected process etc.. etc.. This should be made accessible from all forms in the app at any time... How could I do this... Is there any place like "Session" in ASP.NET here... Further How do coders generally pass information from one form to another... Here I want to pass on the info I acquired in the first form to the subsequent forms... I use constructor overloading and pass the values as parameters... I'm pretty sure there has to be a better way to do it... Thanks for your time...

  • Testing Zend_Controller wich is using Twitter API

    - by ArneRie
    Hi, iam trying to write an unit test for an Controller wich calls the Twitter API through an Service class. /** * Authenticate Step 1 for Twitter */ public function authenticateAction() { $this->service->authenticate(); } The Service does: /** * Authenticate with twitter * * @return void */ public function authenticate() { $consumer = new Zend_Oauth_Consumer($this->config); $token = $consumer->getRequestToken(); $this->session->twitterRequestToken = serialize($token); $consumer->redirect(); exit; } My Problem is, i have no idea to repleace the authenticate action inside the service for the unit test. I dont want to call the Twitter API while the tests run. Is there any Mocking Framework wich can do such things?

  • WCF Caching Solution - Need Advice

    - by Brandon
    The company I work for is looking to implement a caching solution. We have several WCF Web Services hosted and we need to cache certain values that can be persisted and fetched regardless of a client's session to a service. I am looking at the following technologies: Caching Application Block 4.1 WCF TCP Service using HttpRuntime Caching Memcached Win32 and Client Microsoft AppFabric Caching Beta 2 Our test server is a Windows Server 2003 with IIS6, but our production server is Windows Server 2008, so any of the above options would work (except for AppFabric Caching on our test server). Does anyone have any experience with any of these? This caching solution will not be used to store a lot of data, but it will need to be fetched from frequently and fast. Thanks in advance.

  • Web services Authentication Jungle

    - by redben
    I have been doing some research lately about best approaches to authenticating web services calls (REST SOAP or whatever). But none of the Approaches convinced me... But i still can't a make a choise... Some talk about SSL and http basic authentication -login/password- which just seems weird for a machine (i mean having to assign a login/password to a machine, or is it not ?). Some others say API keys (seems like these scheme is more used for tracking and not realy for securing). Some say tokens (like session IDs) but shouldn't we stay stateless (especially if in REST style) ? In my use case, when a remote app is calling one of our web services, i have to authenticate the calling application obviously, and the call must - if applicable - tell me which user it impersonates so i can deal with authorization later. Any thoughts ?

  • NHibernate 'IdentifierGenerationException' on an Update trigger

    - by Jan Jongboom
    In my database I have an id column defined as [autonumber] [int] IDENTITY(1,1) NOT NULL which is mapped in my .hbm.xml like: <id name="Id" column="autonumber" type="int"> <generator class="identity" /> </id> When calling session.Save() updates are successful committed to the database. When adding a versioning trigger I however get the error this id generator generates Int64, Int32, Int16 of type IdentifierGenerationException. The trigger is defined as: ALTER TRIGGER [dbo].[CatchUpdates_NVM_FDK_Kenmerken] ON [dbo].[NVM_FDK_Kenmerken] INSTEAD OF UPDATE AS BEGIN SET NOCOUNT ON UPDATE NVM_FDK_Kenmerken SET idIsActive = 0 WHERE internalId IN (SELECT internalId FROM INSERTED) INSERT INTO dbo.NVM_FDK_Kenmerken ( vestigingNummer , internalId , someOtherColumns, dateInserted, idIsActive ) SELECT vestigingNummer, internalId, someOtherColumns, GETDATE(), 1 FROM INSERTED END What am I doing wrong here? When doing manual updates everything works just fine and as expected.

  • accessing required modules from other modules

    - by john smith
    I have a bare-bone express application, exactly the one that is created with the express command. I have installed socket.io and attached it to my server, like this: var app = express(), server = http.createServer(app), io = io.listen(server); server.listen(8000); Now, I also have the routes files, which is called like this: app.get('/', routes.index); Inside this module I have the following function: exports.index = function(req, res){ socket.emit('news', { message: "foo" }); }; This obviously leads to a 500 reference error, because the routes file is an exportable module, and obviously has no idea what the socket is, as it is located in the app.js file. Is there a way I can access this socket object from this, or any other file? Please note that it is attached to the express generated app. extra: what about getting/setting session data? Thanks in advance.

  • Trigger local program execution from browser

    - by DroidIn.net
    First and foremost: I know it's not right or even good thing to do but my current customer will not cave in. So here's what he is asking for (this is for in-house-behind-a-firewall-etc project). In the web report I need to supply a link which points to the executable script that lives on the universally mapped location (network file server). When user clicks on it it is expected to run on the local client starting local executable which should be pre-installed on the client's box. It should be agnostic to OS (Windows or Linux) and the browser used. Customer doesn't mind to click on angry pop-up alerts but he wants to do it once per client browser (or at minimum - session). QUESTION: Will trusted Java applet be able to do it? Or is the any other (better, simpler) ways of achieving the same? ActiveX control is out of question

  • Getting all the cookies including those from google analytics from one webpage

    - by DixieFlatline
    Hello! I use apache 4 java libs for http get connections. I get all cookies from 2 other pages. But one other webpage contains google analytics cookies(utma,utmz...) and classic session id cookie (checked with firebug). When i try to get the cookies i only get sesson id cookie. Is there any trick to get all the cookies from java in connection with google analytics? If i want to make a http post, it seems that i have to send google analytics cookies too. I can copy my code if somebody wants, but it works on other pages(for printing cookies). Thank you

  • Custom User Management for Google App Engine Java

    - by Gopi
    I am using GAE Java for a multi-user application. There are multiple users with different roles. Each user can login, do some operations and logout. The business restricts me from using Google User Service and I need to implement my own for authentication and session management. Can anyone please share with me how should I go about implementing my own user management? I have read its very tricky to implement own user management. Any pointers in terms of best approaches/ design / existing frameworks if any ? I could see some similar posts but they are for python.

  • Saving contents of ApplicationState in ASP.Net (MVC)

    - by Saqib
    I have an internal app used to edit XML files on disk. The XML files are loaded into an object model which is stored in ApplicationState. I need to save this data. The one option is to do this every time the user changes some data. However, this seems a bit inefficient - writing the data out to disk each time a change is made. Instead, is it possible to be notified whenever the user closes their browser, plus just before the web server exits? Thus, the data would be saved each time a session ends, plus when the computer shuts down, etc. I thought that Application_End(), Application_Error() and Session_End() in Global.asax would provide this, but these methods don't seem to be called.

  • Need to map classes to different databases at runtime in Hibernate

    - by serg555
    I have MainDB database and unknown number (at compile time) of UserDB_1, ..., UserDB_N databases. MainDB contains names of those UserDB databases in some table (new UserDB can be created at runtime). All UserDB have exactly the same table names and fields. How to handle such situation in Hibernate? (database structure cannot be changed). Currently I am planning to create generic User classes not mapped to anything and just use native SQL for all queries: session.createSQLQuery("select * from " + db + ".user where id=1") .setResultTransformer(Transformers.aliasToBean(User.class)); Is there anything better I can do? Ideally I would want to have mappings for UserDB tables and relations and use HQL on required database.

  • SQLAlchemy declarative syntax with autoload in Pylons

    - by Juliusz Gonera
    I would like to use autoload to use an existings database. I know how to do it without declarative syntax (model/_init_.py): def init_model(engine): """Call me before using any of the tables or classes in the model""" t_events = Table('events', Base.metadata, schema='events', autoload=True, autoload_with=engine) orm.mapper(Event, t_events) Session.configure(bind=engine) class Event(object): pass This works fine, but I would like to use declarative syntax: class Event(Base): __tablename__ = 'events' __table_args__ = {'schema': 'events', 'autoload': True} Unfortunately, this way I get: sqlalchemy.exc.UnboundExecutionError: No engine is bound to this Table's MetaData. Pass an engine to the Table via autoload_with=<someengine>, or associate the MetaData with an engine via metadata.bind=<someengine> The problem here is that I don't know where to get the engine from (to use it in autoload_with) at the stage of importing the model (it's available in init_model()). I tried adding meta.Base.metadata.bind(engine) to environment.py but it doesn't work. Anyone has found some elegant solution?

  • getting a gridview and dropdownlist to remember their states after navigate away and back button scr

    - by nat
    hi i have a page filling a gridview which is all working fine. the grid is basically the result of a search .. the filters for which are a number of dropdowns and a couple of textboxes the data from the grid and dropdowns are saved in the session and the whole page lives inside an updatepanel when i navigate away from the page (as it happens by clicking a link inside the grid) and then back button to it, all the droppers are back to their unselected values and the grid is nowhere to be seen.. i understand that this is because of the scriptmanager doesnt do 'standard' postbacks so the browser doesnt realise what has happened. however i have set the EnableHistory to true in the scriptmanager is there an easy way to get this to remember without dropping the updatepanel/scriptmanager? also to complicate things further the scriptmanger /updatepanel is actually in a master page. so not really sure how i can get the navigate bits to work in the scriptmanager.. clearly i am a bit confuised and any help that someone could provide would be happily received thanks nat

  • Firefox why window.opener is defined even for a new tab

    - by jonny
    Hi! I am porting quite old corp application from IE to Firefox. Here is my situation. User goes away from computer for a while and his session becomes expired. When user tries to access something in popup, he is being redirected to login page (in popup window). In login page onload event popup window chain is being closed and root page refreshed (in root page tab user is redirected to login page). The guy before me wrote this like this: if window.top.opener is undefined, we're not in popup. That's why I am getting non-stoppable refresh in Firefox. Why in Firefox window.opener is still defined and points to same window, even if this is a new tab, not popup? How should I correctly determine that current window is popup?

  • Code igniter authentication code in controller security question

    - by Prime Studios
    I have a main controller to handle the very front-end of my authentication system, it handles login, logout, update user info, etc. functions that I anticipate calling by POST'ing from views/forms. What about something like a "delete_user" function though? My thoughts are a button in someones admin panel would say "Delete Account" and it would post to "/auth/delete", and the function would delete the user based on their session username or id. This seems a bit open ended, you could send out a link to someone and when they opened it while in that application it would delete their account.. Whats the best way to handle this?

  • jquery cookie - hoursToLive

    - by mathiregister
    Hi guys, i'm using the jquery cookie plugin. Everything works fine except the fact that I have no idea how to set an expiration-time for the cookie? $.cookie('opt_visible', 'true'); the jquery-cookie documentation says: hoursToLive (DEPRECATED for expiresAt) NUMBER For how many hours should the cookie be valid? (Passing 0 means to delete the cookie at the end of the browser session--this is default. Negative values will delete the cookie, but you should use the del() method instead.) That's exactly what I'd like to have. The cookie should be available as long as i'm browsing the site. As soon as i close the window or browsertab, the cookie should be deleted. How can i implement this hoursToLive thingy to my mentioned line above? Thank you

  • Exception "Illegal attempt to associate a collection with two open sessions" when saving object

    - by Alex
    I am using CastleProject ActiveRecord and I use lazy load feature of this ORM. In order to make lazy load work, it is required to create SessionScope. I do this in Program.cs: public static SessionScope sessionScope; private static void InitializeActiveRecord() { ActiveRecordStarter.Initialize(); sessionScope = new SessionScope(); } This works fine for loading, however, when I try to save my objects, I get an exception saying "Illegal attempt to associate a collection with two open sessions". I guess this is due to the fact that I created one session myself. How to avoid this exception?

  • simple EJB jar deployed in jboss with its own log4j configuration

    - by user309281
    Hi All I have a simple EJB jar with a stateless session bean, deployed in JBOSS AS 4.2.2, unde r/server/default/deploy. The bean is registered under JNDI tree as viewed from jboss jmx console and I am able to access it through a remote java client outside JBOSS. Inside EJB jar, I have added some logging to be written to a separate log file, using apache log4j jar and log4j.xml. But I am not able to view any of the logs. Also I do not wish to use jboss-log4j.xml, since there will be many other EJBs to be deployed and wish to have separate log4j for each EJB application. Here is my one of the EJB-jar contents: EJB_DS.jar: log4j.xml classes apache log4j jar is added to /server/default/lib path. Kindly highlight if i have missed any points for enabling log4j configuration With Regards, Krishna

  • Autotest notifications on Ubuntu virtual environment

    - by Luciano
    I am having trouble getting Rails autotest notifications to work on the Engine Yard Vagrant environment. On the Mac, I normally get the notifications via Growl. However, on the virtual environment (which runs Ubuntu) that doesn't work. I tried running Linux notification setups such as libnotify+autotest-notification, but I get the following error: libnotify-Message: Unable to get session bus: /bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed. ** (notify-send:1004): CRITICAL **: dbus_g_proxy_connect_signal: assertion `DBUS_IS_G_PROXY (proxy)' failed ** (notify-send:1004): CRITICAL **: dbus_g_proxy_connect_signal: assertion `DBUS_IS_G_PROXY (proxy)' failed ** (notify-send:1004): CRITICAL **: dbus_g_proxy_call: assertion `DBUS_IS_G_PROXY (proxy)' failed Another path would be to have Growl receive the notifications remotely, but I don't even know where to begin with that... Any suggestions?

  • request payload versus query string parameters

    - by Sarah Sides
    I am absolutely in the dark when it comes to this request payload that I'm seeing in my Chrome browser. A Query string will have a variable attached like session:2g0SoEE but this payload has just one long string I'm guessing is in base64. I do understand that the request payload can have whatever, but how do I use it? Can I do a post with jquery and send this request payload? For example: $.post(url, {variable: "variable"}, function(data){}); When this posts it will send &variable=variable this will be found as query string parameter in the headers sent in chrome. In this game I'm playing I see another piece of info being sending in the header called a payload request. I'm a confused as to how this is read, used, made, how I can reduplicate this? Here is something similar: Chrome is caching an HTTP PUT request and How to retrieve Request Payload
