  • Redirection on the last Slideshow-Element with Jquery

    - by Agssl
    Hi, I'm very new to Jquery and want to realize a manual slideshow with a page-redirect on the last "next"-button. I detect the last Slide-Element with CSS-Classes and then I want to add a Class to the next button to declare that it is the last next-button of the whole Slideshow. The half of my Code works :) – If I navigate to the last Slide-Element, Jquery adds the Class "last" to the button and if I click on the button with this Class, I'm redirected to the next page – that's what I want. But if I navigate to the last Slide-Element, then click a few times the "prev"-button and then again the next button, I'm instantly redirected although the Class "last" was removed. Thanks in advance and sorry for my bad english. Here's my Code: $(document).ready(function(){ $("#image_nav a:first").attr('id', 'firstSlide'); $("#image_nav a:last").attr('id', 'lastSlide'); $(".dritte_ebene li:first").attr('id', 'firstNavi'); $(".dritte_ebene li:last").attr('id', 'lastNavi'); //Redirect to the next page $("a").click(function(){ if ($("#lastSlide").hasClass("activeSlide")) { $("#weiter").addClass("last"); $('.slide').cycle('pause'); $(".last").click(function(){ window.location.replace("[+PJN_next+]"); }); } }); //Remove "last" if prev is clicked $('#zurueck').click(function(){ $("#weiter").removeClass("last"); }); });

  • Namespaces combined with TFS / Source Control explanation

    - by Christian
    As an ISV company we slowly run into the "structure your code"-issue. We mainly develop using Visual Studio 2008 and 2010 RC. Languages c# and vb.net. We have our own Team Foundation Server and of course we use Source Control. When we started developing based on the .NET Framework, we also begun using Namespaces in a primitive way. With the time we 'became more mature', i mean we learned to use the namespaces and we structured the code more and more, but only in the solution scope. Now we have about 100 different projects and solutions in our Source Safe. We realized that many of our own classes are coded very redundant, i mean, a Write2Log, GetExtensionFromFilename or similar Function can be found between one and 20 times in all these projects and solutions. So my idea is: Creating one single kind of root folder in Source Control and start an own namespace-hierarchy-structure below this root, let's name it CompanyName. A Write2Log class would then be found in CompanyName.System.Logging. Whenever we create a new solution or project and we need a log function, we will 'namespace' that solution and place it accordingly somewhere below the CompanyName root folder. To have the logging functionality we then import (add) the existing project to the solution. Those 20+ projects/solutions with the write2log class can then be maintained in one single place. To my questions: - is that a good idea, the philosophy of namespaces and source control? - There must be a good book explaining the Namespaces combined with Source Control, yes? any hints/directions/tips? - how do you manage your 50+ projects?

  • Maven doesn't compile target/hibernate3/generated-sources

    - by mmm
    Can someone tell me how to configure maven for it also to compile sources from the target/hibernate3/generated-sources directory? I have already read this and other posts but they don't seem to solve my problem (which indeed seems trivial). I have used the bottom-up approach hibernate configuration for cfg.xml, hbm.xml and POJO generation (i.e. auto-generated the complete hibernate configuration out of an existing database schema). I'm also only using standard maven and hibernate3-plugin directory layouts. Yet, when executing mvn compile in the command-line while my sources are in the src/main/java and the generated sources in /target/hibernate3/generated-sources only the ones from src/main/java get compiled and copied into target/classes. I wouldn't like to generate sources into src/main/java as I'd like mvn clean to clean them. I'd like to solve the problem using command-line, plugins and pom.xml only. Is there a way to configure maven-compiler-plugin to do so? Or is there another way? Regards and thanks for any help.

  • Java Runtime Exception

  • ASP.NET MVC Using Castle Windsor IoC

    - by Mad Halfling
    I have an app, modelled on the one from Apress Pro ASP.NET MVC that uses castle windsor's IoC to instantiate the controllers with their respective repositories, and this is working fine e.g. public class ItemController : Controller { private IItemsRepository itemsRepository; public ItemController(IItemsRepository windsorItemsRepository) { this.itemsRepository = windsorItemsRepository; } with using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using Castle.Windsor; using Castle.Windsor.Configuration.Interpreters; using Castle.Core.Resource; using System.Reflection; using Castle.Core; namespace WebUI { public class WindsorControllerFactory : DefaultControllerFactory { WindsorContainer container; // The constructor: // 1. Sets up a new IoC container // 2. Registers all components specified in web.config // 3. Registers all controller types as components public WindsorControllerFactory() { // Instantiate a container, taking configuration from web.config container = new WindsorContainer(new XmlInterpreter(new ConfigResource("castle"))); // Also register all the controller types as transient var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes() where typeof(IController).IsAssignableFrom(t) select t; foreach (Type t in controllerTypes) container.AddComponentWithLifestyle(t.FullName, t, LifestyleType.Transient); } // Constructs the controller instance needed to service each request protected override IController GetControllerInstance(Type controllerType) { return (IController)container.Resolve(controllerType); } } } controlling the controller creation. I sometimes need to create other repository instances within controllers, to pick up data from other places, can I do this using the CW IoC, if so then how? I have been playing around with the creation of new controller classes, as they should auto-register with my existing code (if I can get this working, I can register them properly later) but when I try to instantiate them there is an obvious objection as I can't supply a repos class for the constructor (I was pretty sure that was the wrong way to go about it anyway). Any help (especially examples) would be much appreciated. Cheers MH

  • Python metaclass for enforcing immutability of custom types

    - by Mark Lehmacher
    Having searched for a way to enforce immutability of custom types and not having found a satisfactory answer I came up with my own shot at a solution in form of a metaclass: class ImmutableTypeException( Exception ): pass class Immutable( type ): ''' Enforce some aspects of the immutability contract for new-style classes: - attributes must not be created, modified or deleted after object construction - immutable types must implement __eq__ and __hash__ ''' def __new__( meta, classname, bases, classDict ): instance = type.__new__( meta, classname, bases, classDict ) # Make sure __eq__ and __hash__ have been implemented by the immutable type. # In the case of __hash__ also make sure the object default implementation has been overridden. # TODO: the check for eq and hash functions could probably be done more directly and thus more efficiently # (hasattr does not seem to traverse the type hierarchy) if not '__eq__' in dir( instance ): raise ImmutableTypeException( 'Immutable types must implement __eq__.' ) if not '__hash__' in dir( instance ): raise ImmutableTypeException( 'Immutable types must implement __hash__.' ) if _methodFromObjectType( instance.__hash__ ): raise ImmutableTypeException( 'Immutable types must override object.__hash__.' ) instance.__setattr__ = _setattr instance.__delattr__ = _delattr return instance def __call__( self, *args, **kwargs ): obj = type.__call__( self, *args, **kwargs ) obj.__immutable__ = True return obj def _setattr( self, attr, value ): if '__immutable__' in self.__dict__ and self.__immutable__: raise AttributeError( "'%s' must not be modified because '%s' is immutable" % ( attr, self ) ) object.__setattr__( self, attr, value ) def _delattr( self, attr ): raise AttributeError( "'%s' must not be deleted because '%s' is immutable" % ( attr, self ) ) def _methodFromObjectType( method ): ''' Return True if the given method has been defined by object, False otherwise. ''' try: # TODO: Are we exploiting an implementation detail here? Find better solution! return isinstance( method.__objclass__, object ) except: return False However, while the general approach seems to be working rather well there are still some iffy implementation details (also see TODO comments in code): How do I check if a particular method has been implemented anywhere in the type hierarchy? How do I check which type is the origin of a method declaration (i.e. as part of which type a method has been defined)?

  • Why Java language does not offer a way to declare getters and setters of a given "field" through ann

    - by zim2001
    I actually happily design and develop JEE Applications for quite 9 years, but I realized recently that as time goes by, I feel more and more fed up of dragging all these ugly bean classes with their bunch of getters and setters. Considering a basic bean like this : public class MyBean { // needs getter AND setter private int myField1; // needs only a getter, no setter private int myField2; // needs only a setter, no getter private int myField3; /** * Get the field1 * @return the field1 */ public int getField1() { return myField1; } /** * Set the field1 * @param value the value */ public void setField1(int value) { myField1 = value; } /** * Get the field2 * @return the field2 */ public int getField2() { return myField2; } /** * Set the field3 * @param value the value */ public void setField3(int value) { myField3 = value; } } I'm dreaming of something like this : public class MyBean { @inout(public,public) private int myField1; @out(public) private int myField2; @in(public) private int myField3; } No more stupid javadoc, just tell the important thing... It would still be possible to mix annotation and written down getters or setters, to cover cases when it should do non-trivial sets and gets. In other words, annotation would auto-generate the getter / setter code piece except when a literate one is provided. Moreover, I'm also dreaming of replacing things like that : MyBean b = new MyBean(); int v = b.getField1(); b.setField3(v+1); by such : MyBean b = new MyBean(); int v = b.field1; b.field3 = v+1; In fact, writing "b.field1" on the right side of an expression would be semantically identical to write "b.getField1()", I mean as if it has been replaced by some kind of a preprocessor. It's just an idea but I'm wondering if I'm alone on that topic, and also if it has major flaws. I'm aware that this question doesn't exactly meet the SO credo (we prefer questions that can be answered, not just discussed) so I flag it community wiki...

  • How do I 'addChild' an DisplayObject3d from another class? (Papervision3d)

    - by Sandor
    Hi All Im kind of new in the whole papervision scene. For a school assignment I'm making a panorama version of my own room using a cube with 6 pictures in it. It created the panorama, it works great. But now I want to add clickable objects in it. One of the requirements is that my code is OOP focused. So that's what I am trying right now. Currently I got two classes - Main.as (Here i make the panorama cube as the room) - photoWall.as (Here I want to create my first clickable object) Now my problem is: I want to addChild a clickable object from photoWall.as to my panorama room. But he doesn't show it? I think it has something to do with the scenes. I use a new scene in Main.as and in photoWall.as. No errors or warnings are reported This is the piece in photoWall.as were I want to addChild my object (photoList): private function portret():void { //defining my material for the clickable portret var material : BitmapFileMaterial = new BitmapFileMaterial('images/room.jpg'); var material_list : MaterialsList = new MaterialsList( { front: material, back: material } ); // I don't know if this is nessecary? that's my problem scene = new Scene3D(); material.interactive = true; // make the clickable object as a cube var photoList : DisplayObject3D = new Cube(material_list, 1400, 1400, 1750, 1, 4, 4, 4); // positioning photoList.x = -1400; photoList.y = -280; photoList.z = 5000; //mouse event photoList.addEventListener( InteractiveScene3DEvent.OBJECT_CLICK, onPress); // this is my problem! I cannot see 'photoList' within my scene!!! scene.addChild(photoList); // trace works, so the function must be loaded. trace('function loaded'); } Hope you guys can help me out here. Would really be great! Thanks, Sandor

  • Wrappers/law of demeter seems to be an anti-pattern...

    - by Robert Fraser
    I've been reading up on this "Law of Demeter" thing, and it (and pure "wrapper" classes in general) seem to generally be anti patterns. Consider an implementation class: class Foo { void doSomething() { /* whatever */ } } Now consider two different implementations of another class: class Bar1 { private static Foo _foo = new Foo(); public static Foo getFoo() { return _foo; } } class Bar2 { private static Foo _foo = new Foo(); public static void doSomething() { _foo.doSomething(); } } And the ways to call said methods: callingMethod() { Bar1.getFoo().doSomething(); // Version 1 Bar2.doSomething(); // Version 2 } At first blush, version 1 seems a bit simpler, and follows the "rule of Demeter", hide Foo's implementation, etc, etc. But this ties any changes in Foo to Bar. For example, if a parameter is added to doSomething, then we have: class Foo { void doSomething(int x) { /* whatever */ } } class Bar1 { private static Foo _foo = new Foo(); public static Foo getFoo() { return _foo; } } class Bar2 { private static Foo _foo = new Foo(); public static void doSomething(int x) { _foo.doSomething(x); } } callingMethod() { Bar1.getFoo().doSomething(5); // Version 1 Bar2.doSomething(5); // Version 2 } In both versions, Foo and callingMethod need to be changed, but in Version 2, Bar also needs to be changed. Can someone explain the advantage of having a wrapper/facade (with the exception of adapters or wrapping an external API or exposing an internal one).

  • UIScrollview calling superviews layoutSubviews when scrolling?

    - by marchinram
    Hello, I added a UITableView as a subview to a custom UIView class I'm working on. However I noticed that whenever I scroll the table it calls my classes layoutSubviews. I'm pretty sure its the UIScrollview that the table is inheriting from which is actually doing this but wanted to know if there is a way to disable this functionality and if not why is it happening? I don't understand why when you scroll a scrollview it needs its superview to layout its subviews. Code: @implementation CustomView - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { self.clipsToBounds = YES; UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 15.0, 436.0, 132.0) style:UITableViewStylePlain]; tableView.dataSource = self; tableView.delegate = self; tableView.separatorStyle = UITableViewCellSeparatorStyleNone; tableView.backgroundColor = [UIColor clearColor]; tableView.showsVerticalScrollIndicator = NO; tableView.contentInset = UIEdgeInsetsMake(kRowHeight, 0.0, kRowHeight, 0.0); tableView.tag = componentIndex; [self addSubview:tableView]; [tableView release]; } return self; } - (void)layoutSubviews { // This is called everytime I scroll the tableview } @end

  • JAXB - Beans to XSD or XSD to beans?

    - by bajafresh4life
    I have an existing data model. I would like to express this data model in terms of XML. It looks like I have two options if I'm to use JAXB: Create an XSD that mirrors my data model, and use xjc to create binding objects. Marshalling and unmarshalling will involve creating a "mapping" class that would take my existing data objects and map them to the objects that xjc created. For example, in my data model I have a Doc class, and JAXB would create another Doc class with basically the same exact fields, and I would have to map from my Doc class to xjc's Doc class. Annotate my existing data model with JAXB annotations, and use schemagen to generate an XSD from my annotated classes. I can see advantanges and disadvantages of both approaches. It seems that most people using JAXB start with the XSD file. It makes sense that the XSD should be the gold standard truth, since it expresses the data model in a truly cross-platform way. I'm inclined to start with the XSD first, but it seems icky that I have to write and maintain a separate mapping class that shuttles data in between my world and JAXB world. Any recommendations?

  • Job Opportunities

    - by James
    I have a few questions about my job opportunities and I appreaciate it if people could give me some feedback on what I should have in front of me. I am graduatating from a University of Wisconsin--La Crosse this December with a degree in CS and a math minor. I have a cumulative GPA of 3.84 and a major GPA of 4.0 right now (though I still have many classes in front of me). I already have a degree from the U of Minnesota (History, 3.69 GPA) and have worked in the business world for 3+ years (working for a small company in the baseball world, doing some computer programming, statistical research, operations work, technical writing, etc.) I know Java and C well, also am comfortable with Perl. I should have a good grasp of SQL by graduation. I am looking to get a nice programming job (and will be open to moving). Anyone have any advice on things I should learn etc? Also, I would like to know what everyone thinks about my chances of landing a decent job (I realize that is subjective). Also, any ideas on salary I should be looking for (say I am working a metropolitan area). Thanks.

  • How to make Fluent NHibernate ignore Dictionary properties

    - by Matt Winckler
    I'm trying to make Fluent NHibernate's automapping ignore a Dictionary property on one of my classes, but Fluent is ignoring me instead. Ignoring other types of properties seems to work fine, but even after following the documentation and adding an override for the Dictionary, I still get the following exception when BuildSessionFactory is called: The type or method has 2 generic parameter(s), but 1 generic argument(s) were provided. A generic argument must be provided for each generic parameter. I've tried overriding by property name: .Override<MyClass>(map => { map.IgnoreProperty(x => x.MyDictionaryProperty); }) and also tried implementing ignores using a custom attribute, both of which result in the same exception from BuildSessionFactory. The only thing so far that makes this exception go away is removing the Dictionary property entirely. My question seems to be identical to this one which was never answered (though I'll expand the scope by stating it doesn't matter whether the dictionary is on an abstract base class; the problem always happens for me regardless of what class the property is on). Any takers this time around?

  • Core Data + Core Animation/CALayer together??

    - by ivanTheTerrible
    I am making an Cocoa app with custom interfaces. So far I have implemented one version of the app using CALayer doing the rendering, which has been great given the hierarchical structure of CALayers, and its [hitTest:] function for handling mouse events. In this early version, the model of the app are my custom classes. However, as the program grows I feel the urge of using Core Data for the model, not just for the ease of binding/undo management, but also want to try out the new technology. My method so far: In Core Data: creating a Block entity, with attributes xPos, yPos, width, height...etc. Then, creating a BlockView : CALayer class for drawing, which uses methods such as self.position.x = [self valueForKey:@"xPos"] to fetch the values from the model. In this case, every BlockView object has to also keep a local copy of xPos, which is NOT good. Do any of you guys have better suggestions? Edit: This app is a information visualization tool. So the positions, dimensions of the blocks are important, and should be persisted for later analysis.

  • Should the entity framework + self tracking entities be saving me time

    - by sipwiz
    I've been using the entity framework in combination with the self tracking entity code generation templates for my latest silverlight to WCF application. It's the first time I've used the entity framework in a real project and my hope was that I would save myself a lot of time and effort by being able to automatically update the whole data access layer of my project when my database schema changed. Happily I've found that to be the case, updating my database schema by adding a new table, changing column names, adding new columns etc. etc. can be propagated to my business object classes by using the update from database option on the entity framework model. Where I'm hurting is the CRUD operations within my WCF service in response to actions on my Silverlight client. I use the same self tracking entity framework business objects in my Silverlight app but I find I'm continually having to fight against problems such as foreign key associations not being handled correctly when updating an object or the change tracker getting confused about the state of an object at the Silverlight end and the data access operation within the WCF layer throwing a wobbly. It's got to a point where I have now spent more time dealing with this quirks than I have on my previous project where I used Linq-to-SQL as the starting point for rolling my own business objects. Is it just me being hopeless or is the self tracking entities approach something that should be avoided until it's more mature?

  • Java Robot key activity seems to stop working while certain software is running

    - by Mike Turley
    I'm writing a Java application to automate character actions in an online game overnight (specifically, it catches fish in Final Fantasy XI). The app makes heavy use of java's Robot class both for emulating user keyboard input and for detecting color changes on certain parts of the screen. It also uses multithreading and a swing GUI. The application seems to work perfectly when I test it without the game running, just using screenshots to trigger the apps responses into notepad. But for some reason, when I actually launch FFXI and start the program, all of my keyboard and mouse manipulations just stop working altogether. The program is still running, and the Robot class is still able to read pixel colors. But Robot.keyPress, Robot.keyRelease, Robot.mouseMove, Robot.mousePress and Robot.mouseRelease all do nothing. It's the strangest thing-- to test it, I wrote a simple loop that just keeps typing letters, and focused notepad. I'd then start the game, refocus notepad, and it would do nothing. Then I'd exit the game, and it'd start working again immediately. Has anyone else come across something like this, where specific software will stop certain functions of java from working? Also, to make this more interesting-- Last year I wrote a very similar program using the same classes and programming techniques to automate healing a party in the game as they fight. Last year, this program worked perfectly. After running into these problems I dug up that old program, ran it without making any changes, and found that it too was having the same problems. The only differences between now and when it was working: I was running Windows Vista and now I'm running Windows 7, and several new Java versions as well as FFXI versions have been released. What the hell is going on? (if anyone needs to see my source code, email me at [email protected]. I'm trying to keep it to myself.)

  • Running multiple instances of tomcat in eclipse WTP

    - by lisak
    Hey, SCENARIO: 10 CATALINA_BASEs with own configuration (always the same port numbers 8080, but 10 different IP/hostnames on one host via virtual IPs). created a server in WTP and pick "Use the custom location" option in the server configuration in eclipse. New configuration files are created in workspace/Server/server-name-config/ Set up the server path and deploy path for my catalina base (not the internal .metadata one) After I started it, the new configuration files overwrote the original catalina-base/conf files I had there - I was glad, it should be like this but after I made changes in the eclipse config files workspace/Server/server-name-config/ and restarted the server, the changes didn't appeared in the original files in CATALINA_BASE/conf What the hell is that ? So I set the CATALINA_BASE/conf/server.xml to fault configuration and restarted tomcat from eclipse and it worked ! it took the configuration from /Server/server-name-config/server.xml Then I deleted CATALINA_BASE/conf/server.xml and it said that there is no server.xml in catalina base ! How is it possible ? I don't understand why eclipse WTP developers made so tight integration. There should by just symbolic links in /Server/server-name-config/ pointing to CATALINA_BASE/conf/ ... now there is a weird system which is totally unpredictable. The changes in /Server/server-name-config/ are not reflected in CATALINA_BASE/conf ... from where the standard bootstrap.jar or other catalina classloaders and classes build server, engine and other objects with particular setting. Moreover the CATALINA_BASEs could be used outside eclipse then. The second problem, I'm setting up various things in CATALINA_BASE/bin/startup.sh and setenv.sh which is easy cause I can use bash for it. Is then modifying VM parameters in the "Open launch configuration" settings the only way how to do it in eclipse ? Sorry for such a huge pile of questions, but I'm annoyed by the fact that it is much better to not use eclipse WTP for this because it is very poorly designed and it's a shame because this would spare me a lot of time. And using the internal .metadata/ instances it's even more terrifying way that the one I described.

Has anyone else had a similar issue or know of how to get around this? function jsshellClient() { this.classDescription = "sdConnector JavaScript Shell Service"; this.classID = Components.ID("{54f7f162-35d9-524d-9021-965a3ba86366}"); this.contractID = "@activestate.com/SDService?type=jsshell;1" this._xpcom_categories = [{category: "sd-service", entry: "jsshell"}]; this.name = "jsshell"; this.prefs = Components.classes["@mozilla.org/preferences-service;1"] .getService(Components.interfaces.nsIPrefService) .getBranch("sdconnector.jsshell."); this.enabled = this.prefs.getBoolPref("enabled"); this.port = this.prefs.getIntPref("port"); this.loopbackOnly = this.prefs.getBoolPref("loopbackOnly"); this.backlog = this.prefs.getIntPref("backlog"); } jsshellClient.prototype = new session(); jsshellClient.prototype.constructor = jsshellClient; When calling generateNSGetFactory on the prototype for this it gives an error in the Error Console in FF4 complaining about the classID. I'm pretty sure that nothing else is using the same GUID so I don't see the problem.

  • MVC View Model Intellisense / Compile error

    - by Marty Trenouth
    I have one Library with my ORM and am working with a MVC Application. I have a problem where the pages won't compile because the Views can't see the Model's properties (which are inherited from lower level base classes). They system throws a compile error saying that 'object' does not contain a definition for 'ID' and no extension method 'ID' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) implying that the View is not seeing the model. In the Controller I have full access to the Model and have check the Inherits from portion of the view to validate the correct type is being passed. Controller: return View(new TeraViral_Blog()); View: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<com.models.TeraViral_Blog>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Index2 </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Index2</h2> <fieldset> <legend>Fields</legend> <p> ID: <%= Html.Encode(Model.ID) %> </p> </fieldset> </asp:Content>

  • Kohana 3 jQuery/AJAX request not working

    - by dscher
    I am trying to post some data to a controller in Kohana 3 using the jQuery AJAX method. I seem to have an issue with the data not getting to where I want it to be. I want the data to go to the /application/classes/controller/stock.php file where the file will process the data. I can't seem to figure this one out. Hopefully someone can help. My jQuery ajax call is: $.ajax({ type: 'POST', url: 'add_stock', data: { 'links': 'link_array' } }); 'add_stock' is the name of the action within the controller. I didn't know what else to try. I've also tried '.' and './' hoping that would be right but it's not. In Firebug, although it says the request was 200 OK, I see that the "RESPONSE" is "Failed to load source for: http://localhost/ddm/v2/stocks/add_stock" and my script in my controller which grabs the data isn't working. Here is that code in case it helps: $links = $_POST['links']; $link_obj = Jelly::factory('link') ->set('stock', $stock->id) ->set('links', $links); $link_obj->save(); I think that the problem is that I'm giving the ajax call the ROUTE and not the actual page it needs to deliver the POST data to. I just can't figure it out here. Any help?

Any help is really appreciated as I am new to this.I am trying to do server side filtering in extjs infinte grid which is sending the below request to rest service. when the page load first time, it sends http://myhost/mycontext/rest/populateGrid?_dc=9999999999999&page=1&start=0&limit=500 when you select filter on name and place, it sends http://myhost/mycontext/rest/populateGrid?_dc=9999999999999&filter=[{"type":"string","value":"Tom","field":"name"},{"type":"string","value":"London","field":"Location"}]&page=1&start=0&limit=500 I am trying to save this in POJO and then sending this to database to retrieve data.

  • Looking for a .Net ORM

    - by SLaks
    I'm looking for a .Net 3.5 ORM framework with a rather unusual set of requirements: I need to create and alter tables at runtime with schemas defined by my end-users. (Obviously, that wouldn't be strongly-typed; I'm looking for something like a DataTable there) I also want regular strongly-typed partial classes for rows in non-dynamic tables, with custom validation and other logic. (Like normal ORMs) I want to load the entire database (or some entire tables) once, and keep it in memory throughout the life of the (WinForms) GUI. (I have a shared SQL Server with a relatively slow connection) I also want regular LINQ support (like LINQ-to-SQL) for ASP.Net on the shared server (which has a fast connection to SQL Server) In addition to SQL Server, I also want to be able to use a single-file database that would support XCopy deployment (without installing SQL CE on the end-user's machine). (Probably Access or SQLite) Finally, it has to be free (unless it's OpenAccess) I'll probably have to write it myself, as I don't think there is an existing ORM that meets these requirements. However, I don't want to re-invent the wheel if there is one, hence this question. I'm using VS2010, but I don't know when my webhost (LFC) will upgrade to .Net 4.0

  • Question about registering COM server and Add Reference to it in a C# project

    - by smwikipedia
    I build a COM server in raw C++, here is the procedure: (1) write an IDL file to define the interface and library. (2) use msidl.exe to compile the IDL file to necessary .h, .c, .tlb files. (3) implement the COM server in C++ and build a .dll file. (4) add the following registry entris: [HKEY_CLASSES_ROOT\RawComCarLib.ComCar.1\CurVer] @="RawComCarLib.ComCar.1" ;CLSID [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}] @="RawComCarLib.ComCar.1" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\InprocServer32] @="D:\com\Project01.dll" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\ProgID] @="RawComCarLib.ComCar.1" [HKEY_CLASSES_ROOT\CLSID{6CC26343-167B-4CF2-9EDF-99368A62E91C}\TypeLib] @="{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}" ;TypeLib [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}] [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0] @="Car Server Type Lib" [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0] [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0\win32] @="D:\com\Project01.tlb" [HKEY_CLASSES_ROOT\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\FLAGS] @="0" [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\TypeLib{E5C0EE8F-8806-4FE3-BC0E-3A56CFB38BEE}\1.0\0\win32] @="C:\Windows\System32\msdatsrc.tlb" (5) I try to add reference to the COM by click the Add Reference in the C# project. (6) In the COM tab, I saw my "Car Server Type Lib", it's ok until now. I try to use the Object Browser to browse my COM lib, but the Visual Studio said "the following components could not be browsed", and I noticed that there's no new reference added to the list in the C# project Reference. I can use the tlbimp.exe to generate a interop.CarCom.dll, and then use the COM through this interop dll, but I want this interop assembly to be generated automatically when I just add reference to the COM. Could someone tell me what's wrong? Many thanks.

  • How to avoid "Illegal type in constant pool" using "ldc_w <classname>" in Jasmin?

    - by jazzdev
    I'm writing a compiler that generates Jasmin code and want to invoke a method that takes a Class as a parameter. public class CTest { public static void main(String[] args) throws Exception { java.lang.reflect.Array.newInstance(CTest.class, 0); } } So in Jasmin, I think that should be: .class public CTest2 .super java/lang/Object .method public static main([Ljava/lang/String;)V .limit stack 2 .limit locals 1 ldc_w CTest2 iconst_0 invokestatic java/lang/reflect/Array/newInstance(Ljava/lang/Class;I)Ljava/lang/Object; pop return .end method When I assemble it and run it I get: Exception in thread "main" java.lang.VerifyError: (class: CTest2, method: main signature: ([Ljava/lang/String;)V) Illegal type in constant pool Looking at the disassembled code for both CTest.class (the Java version) and CTest2.class (the Jasmin version) with "javap -c -verbose" they both appear to set up the constant pool the same way: const #2 = class #16; // CTest const #16 = Asciz CTest; 0: ldc_w #2; //class CTest const #14 = Asciz CTest2; const #17 = class #14; // CTest2 0: ldc_w #17; //class CTest2 I've fixed two bugs in Jasmin already, but I can't see what it's doing wrong when putting the class in the constant pool for "ldc_w" it puts classes in the constant pool for other instructions, like "new" and "anewarray" correctly. I've tried looking at the .class files with TraceClassVisitor in ASM, but it doesn't dump the constant pool. Any ideas what I can try next?
