  • How does cross domain file (receiver) work?

    - by seatoskyhk
    So, how does it work? How come having a receiver.html can allow cross domain communication? I... just... don't understand. For example, (using Heyzap as example) <script type="text/javascript" src="http://tools.heyzap.com/external/tools/v4.js"></script> <script type="text/javascript"> HeyzapTools.load({ game_key: "your-game-key-here", hz_receiver_url: "http://example.com/hz_receiver.html" }); </script> and the hz_receiver.html has this content: <html> <body> <script src="/external/tools/hz_receiver.js" type="text/javascript"></script> </body> </html> so, why it will allow cross domain?

  • Defautlt Contoller in CodeIgniter

    - by gregavola
    Hello everyone, I am wondering if there is any other configuration options for a default controller. For example - if I have a controller called "site" and I set the default controller in the following file: application/config/routes.php to: $route['default_controller'] = "site"; I should be able to go to http://localhost and that brings up the index(); function in the site controller. However, if I try to do go to http://localhost/index.php/index2 to load the index2(); function I get a 404 error. If i change the URL to http://localhost/index.php/site/index2 it works fine - but I thought already set the default controller. Is there any way around this? Any thoughts?

  • How to call a function from a shared library?

    - by Frank
    What is the easiest and safest way to call a function from a shared library / dll? I am mostly interested in doing this on linux, but it would be better if there were a platform-independent way. Could someone provide example code to show how to make the following work, where the user has compiled his own version of foo into a shared library? // function prototype, implementation loaded at runtime: std::string foo(const std::string); int main(int argc, char** argv) { LoadLibrary(argv[1]); // loads library implementing foo std::cout << "Result: " << foo("test"); return 0; } BTW, I know how to compile the shared lib (foo.so), I just need to know an easy way to load it at runtime.

  • Entity framework Update fails when object is linked to a missing child

    - by McKay
    I’m having trouble updating an objects child when the object has a reference to a nonexising child record. eg. Tables Car and CarColor have a relationship. Car.CarColorId CarColor.CarColorId If I load the car with its color record like so this var result = from x in database.Car.Include("CarColor") where x.CarId = 5 select x; I'll get back the Car object and it’s Color object. Now suppose that some time ago a CarColor had been deleted but the Car record in question still contains the CarColorId value. So when I run the query the Color object is null because the CarColor record didn’t exist. My problem here is that when I attach another Color object that does exist I get a Store update, insert error when saving. Car.Color = newColor Database.SaveChanges(); It’s like the context is trying to delete the nonexisting color. How can I get around this?

  • C# how to store those information?

    - by 5YrsLaterDBA
    I have a PrivilegeGroup table, a Privileges table and a link table because the PrivilegeGroup table and the Privileges table is a many to many relationship. I am thinking about load all contents of PrivilegeGroup table and Privilege table into memory from database at beginning when application started. I want to save them in a form easily to look up. Usually we will look up the PrivilegeCode via GroupId. Which structure is good for this purpose? array of list? dictionary?

  • Point IIS at debug folder

    - by mtmurdock
    I am working on an asp.net mvc web service and an Android app that need to be able to communicate with one another. However, when running a web service/web site in Visual Studio it can only be accessed by that machine. So what I want to do is point IIS at my project's bin/debug folder, thus exposing my dev environment to my local network. I know this is possible because my work machine is set up this way, I just don't know how it is done. How do I configure IIS to load a web app from the debug directory of my Visual Studio project?

  • Modify input stream data on the fly

    - by Frizi
    I would like to implement a std::stream modifier/parser, that is doing data manipulation on the fly. Is it possible to create it in form of stream manipulator? For example, i want to strip all the line comments (from any // to the end of line) out of the stdin and pass it to stdout. string str; istream strippingCin = cin >> stripcomments; while(strippingCin.good()) { strippingCin >> str; cout << str; } There may be also a large file input instead of cin, so i don't want to load full stream data into memory at once. Is it possible without writing my own stream class? Maybe is there another route i should take instead?

  • Choose between multiple options with defined probability

    - by Sijin
    I have a scenario where I need to show a different page to a user for the same url based on a probability distribution, so for e.g. for 3 pages the distribution might be page 1 - 30% of all users page 2 - 50% of all users page 3 - 20% of all users When deciding what page to load for a given user, what technique can I use to ensure that the overall distribution matches the above? I am thinking I need a way to choose an object at "random" from a set X { x1, x2....xn } except that instead of all objects being equally likely the probability of an object being selected is defined beforehand.

  • JBoss 4.0.5 startup takes 15 minutes deploying a single war file

    - by dkblinux98
    This instance of JBoss deploys several war files. The rest of the JBoss startup takes about 5 minutes or less. But when it gets to one particular war file, startup just hangs with no further output to the jboss log. It waits there for about 15 minutes and then suddenly the war starts deploying. The rest of the JBoss startup is then fine. What I want to know is what steps do you recommend I take to diagnose the cause of this condition? It is not possible to upgrade this site to a newer version of JBoss nor java (currently 1.5.0.7). It is running on 32-bit CentOS 5.3 Linux on 3 xen-based virtual servers in a load balanced configuration. The code is common to all three servers via an nfs share. This same issue was seen, however, when the 3 servers were physical and the code was local to each server. The servers are each 2 cpu, 4GB RAM servers.

  • Running a ProgressDialog MonoAndroid

    - by user1791926
    I am trying to run a progressDialog that will loading items into a Sqlite datebase on a first load for my application. I get an error message because the application runs the rest of the code in the application before the rest of the data is loaded into the database. How do I make sure the code is completed in the progressDialog before the code in the rest of the program? LocalDatabase DB = new LocalDatabase(); var dbpd = ProgressDialog.Show(this, "Loading Database", "Please wait Loading Data",true); ThreadPool.QueueUserWorkItem((s) =>{ DB.createDB(); RunOnUiThread(() => databaseLoaded()); });

  • Can entities be attached to an ISession that weren't previously attached?

    - by TheCloudlessSky
    I'm playing around with NHibernate 3.0. So far things are pretty cool. I'm trying to attach an entity that wasn't detached previously: var post = new Post(){ Id = 2 } session.Update(post); // Thought this would work but it doesn't. post.Title = "New Title After Update"; session.Flush(); Is this possible so that only Title gets updated? This is currently possible in EntityFramework. I'd like to not have to load Post from the database when I just need to update a few properties.

  • How to deploy updates to .NET website in cluster

    - by royappa
    We are operating a corporate web application on a load-balanced cluster that consists of two identical IIS servers talking to a single MSSQL database. To deploy updates I am using this primitive process: 1) Make a copy of the entire site folder (wwwroot\inetpub\whatever) on each IIS box 2) Download the updated, compiled files onto each IIS box from our development area 3) Shut down IIS both web servers 4) Copy the new and updated files into the wwwroot folder (overwriting any same files) 5) Then restart IIS on both machines When there are database changes involved there are a few other steps. The whole process is fairly quick but it is ugly and fraught with danger, so it has to be done with full concentration. I would like to just push one button to make it all happen. And I want a one-click rollback in case there is a problem (that's the reason I make the copy in step #1). I am looking for tools to manage and improve this process. If it also helped us maintain a changelog, that would be nice. Thanks.

  • How do I get the raw dimensions of a bitmap in an ImageView?

    - by potatoe
    It seems like I might be overlooking something obvious, but I can't figure out how to retrieve the raw (unscaled) dimensions of a bitmap being displayed in an ImageView. For example, if I load a bitmap using Bitmap b = BitmapFactory.decodeResource(...), I can get those dimensions from b.getWidth() and b.getHeight(), and I could pass the bitmap into an ImageView using setImageBitmap(b). But if I have a subclass of ImageView, is there any way to retrieve those dimensions without having to pass them in explicitly? I guess I'm looking for a getImageBitmap() analog of ImageView's setImageBitmap() method, which would retrieve a Bitmap object that I can call getWidth() and getHeight() on. Any other way to retrieve the original dimensions would work too, though.

  • How do I display each view once as they are loaded, in Android?

    - by Joe Masilotti
    I have an Android application that works off of a smaller database, around 300 entries. To view the database, I have created a custom view that contains individual rows of data. Then I query the database, and add each line to a newly created custom view. The problem is that it takes a little white for all of this to be created/loaded, so when you open the application, it sits for a few seconds. How can I load one line of data, then display it, then the next, append it, etc.?

  • What goes in to making a web site that needs to scale?

    - by samoz
    I am planning to build an application that will get a large amount of traffic. (Please don't say I won't get traffic, this is for an internal network, so the traffic will be there. Just trying to avoid the 'You won't get that much traffic, don't worry about it.) What sorts of things do I need to do so that it doesn't simply crash under the load of a large amount of users? What becomes the limiting factors? Database stuff? I/O with front end? I've never really developed a serious web app before and am looking for some help.

  • Empty R environment becomes large file when saved

    - by user1052019
    I'm getting behaviour I don't understand when saving environments. The code below demonstrates the problem. I would have expected the two files (far-too-big.RData, and right-size.RData) to be the same size, and also very small because the environments they contain are empty. In fact, far-too-big.R ends up the same size as bigfile.RData. I get the same results using 2.14.1 and 2.15.2, both on WinXP 5.1 SP3. Can anyone explain why this is happening? Thanks. a <- matrix(runif(1000000, 0, 1), ncol=1000) save(a, file="c:/temp/bigfile.RData") test <- function() { load("c:/temp/bigfile.RData") test <- new.env() save(test, file="c:/temp/far-too-big.RData") test1 <- new.env(parent=globalenv()) save(test1, file="c:/temp/right-size.RData") } test()

  • Running sql scripts against an attached database?

    - by Will
    I've got an MDF attached to an instance of Sql Server 2008 Express, and I need to run some sql scripts against it to generate tables, indexes, etc. But I can't figure out how to get this to work. If I load the scripts in Visual Studio, it only allows me to connect to the server and run it against a database. I can't choose a different provider (Microsoft Sql Server Database File), so I can't select my MDF. This leaves me the only option of running the script as individual queries, but that won't work as it appears it doesn't support TSQL CREATE statements. How can I run my sql script against an attached database?

The site is located at this link any help on this would be appreciated.

  • How does linq decide between inner & outer joins

    - by user287795
    Hi Usually linq is using an left outer join for its queries but on some cases it decides to use inner join instead. I have a situation where that decision results in wrong results since the second table doesn't always have suitable records and that removes the records from the first table. I'm using a linqdatasource over a dbml where the relevant tables are identical but one holds historical records removed from the first. both have the same primary key. and I'm using a dataloadoption to load both tables at once with out round trips. Would you explain why linq decided to use an inner join here? Thanks

  • Jquery - how to create a sophisticated sidebar that smoothly scrolls down with you

    - by Gal
    I probably couldn't depict it better in the title (and if it has a term let me know), but just to quell the obscurity, I was referring to something like this. After you wait for the page to load, see how when you scroll down, the social media left bar stays fixed, but then when you scroll just enough that it meets your upper side, it sticks to it as you scroll further. I wanted to implement something corny and pretentious like that, so does anybody know a tutorial or a method to get that done in jquery? (I can probably do it myself, if I'm not mistaken, just need some sense of direction from savvy jqueryists). Is there a way to know when and how much a user scrolls? Can it be done with id's like the # url appendix to jump to a specific element? Just some ideas...

  • which one consume less resources? opening text file or make an sql query,both a thousand times ?

    - by imin
    hi I've a php website which displays recipes www.trymasak.my, to be exact. The recipes being displayed at the index page is updated about once a day. To get the latest recipes, I just use a mysql query which is something like "select recipe_name, page_views, image from table order by last_updated". So if I got 10000 visitors a day, obviously the query would be made 10000 times a day. A friend told me a better way (in terms of reducing server load) is when I update the recipes, I just put in the latest recipe details (names,images etc) into a text file, and make my page instead of querying a same query for 10,000 times, just get the data from the text file. Is his suggestion really better? If yes, which is the best php command should I use to open, read and close the text file? thanks

  • Set timeout on third-party file request with jQuery

    - by markedup
    I'm trying to integrate a script file hosted by a third party into a new web site. Currently, I'm adding a SCRIPT tag to the DOM for that third-party script file on document ready: $(document).ready( function() { var extScript = document.createElement('script'); extScript.type = 'text/javascript'; extScript.src = 'http://third-party.com/scriptfile.js'; $('head').append(extScript); }); function extScriptCallback() { $('#extWidgetContainer').show(); } But sometimes that third-party script file request times out or takes a long time to respond. So, for the sake of best practice, I want to provide alternative content if the external script takes longer than e.g. 10 seconds to load. How do I achieve this? I've looked at JavaScript's native setTimeout(), as well as jQuery's delay() function, but I'm not sure which I should use--or how. Grateful for any suggestions.
