  • Jquery/Javascript gmail style stuff for message inbox, such as select all message using checkbox etc

    - by Psychonetics
    I am enjoying the fact that I'm here building a private message inbox for my website after building a full user signup/login and activation system when a few months ago I thought I wouldn't have enough patience to learn this stuff. Anyway to my question. I am currently building the private message inbox for my users and wondering if there are any jquery/javascript stuff I can use to make my inbox more like the gmail inbox. E.G. Gmail allows you to select all read messages or unread or starred or unstarred or none of the messages using a checkbox. I would like to add this kind of feature to my website and I'm sure the easiest way to achieve this would be using a jquery/javascript script. I would appreciate if someone could provide some links or info to where I can find several of these types of scripts to use with my inbox page. Thanks EDIT: Would also like to note that I would like the checkbox to be in a dropdown just like gmails.

  • Raise an event when Property Changed using Reflection

    - by Dante
    I am working in C# and I have an object which I can only access using Reflection (for some personal reasons). So, when I need to set some value to one of its properties I do as below: System.Reflection.PropertyInfo property = this.Parent.GetType().GetProperty("SomeProperty"); object someValue = new object(); // Just for example property.SetValue(this.Parent, someValue, null); And, to get its value I use the method GetValue. My question is: Is there a way to fire an event when the property changes using Reflection? Thank you in advance.

  • Making form submissions unique using PHP and HTML

    - by canadiancreed
    Hello all I'm currently developing a page where the user fills out a form, and when submitted they are taken to the next page. When on the next page, I want to have it so that if the user went back to the previous page using the back button, or hit refresh, the submission will not be saved into the DB. Now I recall reading somewhere that if you had a way to make each submission unique, this issue is averted, but after screwing around for hours on end, for the life of me I cannot recall how this could be done (using PHP), so long story short has anyone ran into this, and if so, what was your solution?

  • Trouble using Prototype JS

    - by user309381
    I have three files named like: AjxDm.php db_test website.php What I am trying to do is AjxDm.php in this file I click and I am using Ajax.Request and it directed me to the db_test.php. In this file I am retrieving a value from the database and I assign the value into a dropdown. Again when I try to select one of the options in the dropdown it is direceting me to the Website.php using Ajax.Request with the dropdown selected value and retrieve data from database and display. The problem is that when I call from AjxDm.php to Db_test it works but when I select option in db_test.php it doesn't find a JavaScript function which direct me to the website.php. What can I do to make it work?

  • Corba sequence<octet> a lot slower than using a socket

    - by Totonga
    I have a corba releated question. In my Java app I use typedef sequence Data; Now I played around with this Data vector. If I am right with the Corba specification sequence will either be converted to xs:base64Binary or xs:hexBinary. It should be an Opaque type and so it should not use any marshalling. I tried different idl styles: void Get(out Data d); Data Get(); but what I see is that moving the data using Corba is a lot slower than using a socket directly. I am fine with a little overhead but it looks for me like tha data is still marshalled. Do I need to somehow configure my orb to suppress the marshalling or did I miss something.

  • Using WCF HttpBindings on a LAN

    - by dcw
    We have a WCF-based client server that operates over a LAN. We've been getting along ok by using the NetTcpBinding, chosen because we couldn't get either HttpBinding to work between hosts. (Within a single host works fine, but is not useful for the production environment.) We're now back at the point where we want to explore using either BasicHttpBinding or WsHttpBinding, but we simply can't see the server from the client: even putting in the path to the endpoint into IE fails to see the server. Is there something simple we've overlooked? We're not specifying any security settings (or anything else, for that matter). Should we be doing so (e.g. explicitly setting security settings to None)?

  • Using Core Data Concurrently and Reliably

    - by John Topley
    I'm building my first iOS app, which in theory should be pretty straightforward but I'm having difficulty making it sufficiently bulletproof for me to feel confident submitting it to the App Store. Briefly, the main screen has a table view, upon selecting a row it segues to another table view that displays information relevant for the selected row in a master-detail fashion. The underlying data is retrieved as JSON data from a web service once a day and then cached in a Core Data store. The data previous to that day is deleted to stop the SQLite database file from growing indefinitely. All data persistence operations are performed using Core Data, with an NSFetchedResultsController underpinning the detail table view. The problem I am seeing is that if you switch quickly between the master and detail screens several times whilst fresh data is being retrieved, parsed and saved, the app freezes or crashes completely. There seems to be some sort of race condition, maybe due to Core Data importing data in the background whilst the main thread is trying to perform a fetch, but I'm speculating. I've had trouble capturing any meaningful crash information, usually it's a SIGSEGV deep in the Core Data stack. The table below shows the actual order of events that happen when the detail table view controller is loaded: Main Thread Background Thread viewDidLoad Get JSON data (using AFNetworking) Create child NSManagedObjectContext (MOC) Parse JSON data Insert managed objects in child MOC Save child MOC Post import completion notification Receive import completion notification Save parent MOC Perform fetch and reload table view Delete old managed objects in child MOC Save child MOC Post deletion completion notification Receive deletion completion notification Save parent MOC Once the AFNetworking completion block is triggered when the JSON data has arrived, a nested NSManagedObjectContext is created and passed to an "importer" object that parses the JSON data and saves the objects to the Core Data store. The importer executes using the new performBlock method introduced in iOS 5: NSManagedObjectContext *child = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSPrivateQueueConcurrencyType]; [child setParentContext:self.managedObjectContext]; [child performBlock:^{ // Create importer instance, passing it the child MOC... }]; The importer object observes its own MOC's NSManagedObjectContextDidSaveNotification and then posts its own notification which is observed by the detail table view controller. When this notification is posted the table view controller performs a save on its own (parent) MOC. I use the same basic pattern with a "deleter" object for deleting the old data after the new data for the day has been imported. This occurs asynchronously after the new data has been fetched by the fetched results controller and the detail table view has been reloaded. One thing I am not doing is observing any merge notifications or locking any of the managed object contexts or the persistent store coordinator. Is this something I should be doing? I'm a bit unsure how to architect this all correctly so would appreciate any advice.

  • Repeatedly querying xml using python

    - by Jack
    I have some xml documents I need to run queries on. I've created some python scripts (using ElementTree) to do this, since I'm vaguely familiar with using it. The way it works is I run the scripts several times with different arguments, depending on what I want to find out. These files can be relatively large (10MB+) and so it takes rather a long time to parse them. On my system, just running: tree = ElementTree.parse(document) takes around 30 seconds, with a subsequent findall query only adding around a second to that. Seeing as the way I'm doing this requires me to repeatedly parse the file, I was wondering if there was some sort of caching mechanism I can use so that the ElementTree.parse computation can be reduced on subsequent queries. I realise the smart thing to do here may be to try and batch as many queries as possible together in the python script, but I was hoping there might be another way. Thanks.

  • .htaccess URL is being cut at a space (I'm using Codeigniter)

    - by Ice
    I've used the following code to map https://live.example.com on to http://example.com/api Options +FollowSymLinks RewriteEngine On RewriteCond %{HTTPS} =on RewriteCond %{HTTP_HOST} ^live\.example\.com [NC] RewriteRule (.+)$ "http://example.com/api/$1" [L,P] The following url: https://live.example.com/userlinks/xml/John%20James/MvPjeUTo15/ Is suppose to map onto: http://example.com/api/userlinks/xml/John%20James/MvPjeUTo15/ Instead it maps it to: http://example.com/api/userlinks/xml/John So it seems to cut it at the space. I am using the Codeigniter framework but I am not sure if the problem lies there. Also using %20 or just a space in the url bar produces no different results. Anyone any idea and/or solution why this happens? Thank you very much, Ice

  • Javascript: Using the Module Pattern for larger projects

    - by Rob
    I'm interested in using the Module Pattern to better organize my future projects. Unfortunately, there are only a few brief tutorials and proof-of-concept examples of the Module Pattern. Using the module pattern, I would like to organize projects into this sort of structure: project.arm.object.method(); Where "project" is my global project name, "arm" is a sub-section or branch of the project, "object" is an individual object, and so on to the methods and properties. However, I'm not sure how I should be declaring and organizing multiple "arms" and "objects" under "project". var project = window.project || {}; project.arm = project.arm || {}; project.arm.object = (function() { var privateVar = "Private contents."; function privateMethod() { alert(privateVar); } return { method: privateMethod }; }()); Are there any best practices or conventions when defining a complex module structure? Should I just declare a new arm/object underneath the last?

  • How to perform duplicate key validation using entlib (or DataAnnotations), MVC, and Repository pattern

    - by olivehour
    I have a set of ASP.NET 4 projects that culminate in an MVC (3 RC2) app. The solution uses Unity and EntLib Validation for cross-cutting dependency injection and validation. Both are working great for injecting repository and service layer implementations. However, I can't figure out how to do duplicate key validation. For example, when a user registers, we want to make sure they don't pick a UserID that someone else is already using. For this type of validation, the validating object must have a repository reference... or some other way to get an IQueryable / IEnumerable reference to check against other rows already in the DB. What I have is a UserMetadata class that has all of the property setters and getters for a user, along with all of the appropriate DataAnnotations and EntLib Validation attributes. There is also a UserEntity class implemented using EF4 POCO Entity Generator templates. The UserEntity depends on UserMetadata, because it has a MetadataTypeAttribute. I also have a UserViewModel class that has the same exact MetadataType attribute. This way, I can apply the same validation rules, via attributes, to both the entity and viewmodel. There are no concrete references to the Repository classes whatsoever. All repositories are injected using Unity. There is also a service layer that gets dependency injection. In the MVC project, service layer implementation classes are injected into the Controller classes (the controller classes only contain service layer interface references). Unity then injects the Repository implementations into the service layer classes (service classes also only contain interface references). I've experimented with the DataAnnotations CustomValidationAttribute in the metadata class. The problem with this is the validation method must be static, and the method cannot instantiate a repository implementation directly. My repository interface is IRepository, and I have only one single repository implementation class defined as EntityRepository for all domain objects. To instantiate a repository explicitly I would need to say new EntityRepository(), which would result in a circular dependency graph: UserMetadata [depends on] DuplicateUserIDValidator [depends on] UserEntity [depends on] UserMetadata. I've also tried creating a custom EntLib Validator along with a custom validation attribute. Here I don't have the same problem with a static method. I think I could get this to work if I could just figure out how to make Unity inject my EntityRepository into the validator class... which I can't. Right now, all of the validation code is in my Metadata class library, since that's where the custom validation attribute would go. Any ideas on how to perform validations that need to check against the current repository state? Can Unity be used to inject a dependency into a lower-layer class library?

  • Can I access the function body of an event listener using nodeJS jsdom

    - by Zhami
    I am using jsdom with nodeJS. I load in a large HTML document, and am using jQuery to navigate the DOM. I have a case where I have an element, and I need to access the function body of an event listener (onclick). The event listener was added in the source HTML: <a href="#" onclick="javascript:window.open('http://<rest-of-url>'); return false;"></a> The onclick attribute of the DOM element is undefined. btw: what I really want to do is get the URL (please note that <rest-of-url> is not what is in the source, a real URL spec is there) that is specified in the source.

  • Publish web application from MSBuild Script using VS2010 targets resets working directory

    - by Raoul
    I am trying to automatically publish and deploy my .Net 4 web application automatically from a build script to be run by our continuous integration server. I am using the new _WPPCopyWebApplication target from VS2010 to perform the publish, however it appears to reset the current working directory of the msbuild project to c:\ this causes my prebuild steps to fail as they have relative paths to some external tools. The task I am running from our master.build file is as follows: <Target Name="PublishWeb"> <MSBuild Projects="$(ProjectPath)" Targets="ResolveReferences;_WPPCopyWebApplication" Properties="WebProjectOutputDir=$(DeployPath);OutDir=$(TempOutputFolder)$(WebOutputFolder)\;OutputPath=$(ProjectPath)\bin\Debug;" /> </Target> This does not happen when using the legacy _CopyWebApplication. Does anyone have any idea how to resolve this problem?

  • determine if a restaurant is open now (like yelp does) using database, php, js

    - by vee
    i was wondering if anyone knows how yelp determines what restaurants are "open now"? i'm developing a similar application using html/javascript/php. i was going to have a column in my database for each day, with comma separated hours written in "2243" format (10:43 pm). so for example if a restaurant is open for lunch and dinner it might be "1100,1400,1700,2200". then i'd check (using js) if the current time falls in one of the ranges for the current day. i'd also like to be able to determine if a restaurant is "open tonight", "open late", etc. for those i guess i'd check whether the open range overlaps with certain ranges. is there a better way to do this? particularly, how to store the hours in the database and then determine if they overlap with a given set of hours. thanks.

  • Using jep.invoke() method

    - by hofsoc
    Hi, I need to call a function from a python script and pass in parameters into it. I have a test python script which I can call and run from java using Jepp - this then adds the person. Eg Test.py import Finding from Finding import * f = Finding() f.addFinding("John", "Doe", 27) Within my Finding class I have addFinding(firstname, lastName, age) However, I wish to be able to do this from within java. Should I be using the jep.invoke() method. Does anyone have a hello world example of such a thing being done or forward me to some good examples? Does anyone have any suggestions please? Thanks in advance

  • Prolog: using the sort/2 predicate

    - by Øyvind Hauge
    So I'm trying to get rid of the wrapper clause by using the sort library predicate directly inside split. What split does is just generating a list of numbers from a list that looks like this: [1:2,3:2,4:6] ---split-- [1,2,3,2,4,6]. But the generated list contains duplicates, and I don't want that, so I'm using the wrapper to combine split and sort, which then generates the desired result: [1,2,3,4,6]. I'd really like to get rid of the wrapper and just use sort within split, however I keep getting "ERROR: sort/2: Arguments are not sufficiently instantiated." Any ideas? Thanks :) split([],[]). split([H1:H2|T],[H1,H2|NT]) :- split(T,NT). wrapper(L,Processed) :- split(L,L2), sort(L2,Processed).
