• How to minor updates to Drupal-6 with shared hosting

  - by marty.fried

  I've got Drupal working on a shared host, and I uploaded some modules from my home system successfully, but I've got the message that there is a security update for my version, and I should update immediately. I'm not sure how I'm supposed to do that. It seems like the update is an entire new installation. I originally installed it using the hosting company's installer, Fantastico. Should I simply over-write the existing installation with the new files? Or ignore the message? I realize I shouldn't over-write the sites folder, or anything I've modified. The instructions that come with the download seem to be for a major version upgrade, and are way too much trouble for frequent security updates. Searching Drupal's site shows many other methods, but no indication of anything official. And some were ridiculously error-prone, and not really useful. I don't have shell access to the hosting site, although I can pay extra to get it if I really need to. Or, maybe I can clone the site on my local Linux system, do the update using a script, then upload the whole thing. Does anyone have experience with this situation?

• Applet panels, one fixed size, and dynamic JTextField

  - by Kristoffersen

  Hi, I need an applet which contains one panel. The panel needs to be 550x400 pixels, the JTextField needs to be under the panel dynamic size. I want it to be like this: [topPanel] [textPanel] However I am trying this, and it seems like the panel is filling all the space. The code: import java.awt.BorderLayout; import java.awt.Color; import java.awt.Dimension; import javax.swing.JApplet; import javax.swing.JPanel; import javax.swing.JTextField; public class Client extends JApplet { @Override public void init() { try { java.awt.EventQueue.invokeAndWait(new Runnable() { public void run() { initComponents(); } }); } catch (Exception ex) { ex.printStackTrace(); } } private void initComponents() { JPanel topPanel = new javax.swing.JPanel(); topPanel.setBackground(Color.red); topPanel.setSize(550, 400); topPanel.setPreferredSize(new Dimension(550, 400)); topPanel.setMinimumSize(new Dimension(550, 400)); topPanel.setMaximumSize(new Dimension(550, 400)); JTextField myTextBox = new JTextField(255); getContentPane().add(topPanel, java.awt.BorderLayout.NORTH); getContentPane().add(myTextBox, java.awt.BorderLayout.SOUTH); } // TODO overwrite start(), stop() and destroy() methods } Thanks!

• Hibernate overriding database modifications with detached object state

  - by EugeneP

  I'm gonna go with this design: create an object and keep it alive during all web-app session. And I need to synchronize its state with database state. What I want to achieve is that : IF between my db operations, that is, modifications that I persist to a db someone intentionally spoils table rows, then on next saving to a database all those changes WOULD BE OVERWRITTEN with the object state, that always contains valid data. What Hibernate methods do you recommend me to use to persist the modifications in a database? saveOrUpdate() is a possible solution, but maybe there's anything better? Again, I repeat how it looks. First I create an object without collections. Persist it (save()). Then user provides us with additional data. In a serviceLayer, again, we modify our object in memory (say, populate it with collections) and then, persist it again. So every serviceLayer operation of the next step must simply guarantee that database contains the exact persistent copy of this object that we have in memory. If data in a database differ, it MUST BE OVERRIDDEN with the object (kept in memory) state. What Session operations do you recommend?

• Optional Member Objects

  - by David Relihan

  Okay, so you have a load of methods sprinkled around your systems main class. So you do the right thing and refactor by creating a new class and perform move method(s) into a new class. The new class has a single responsibility and all is right with the world again: class Feature { public: Feature(){}; void doSomething(); void doSomething1(); void doSomething2(); }; So now your original class has a member variable of type object: Feature _feature; Which you will call in the main class. Now if you do this many times, you will have many member-objects in your main class. Now these features may or not be required based on configuration so in a way it's costly having all these objects that may or not be needed. Can anyone suggest a way of improving this? At the moment I plan to test in the newly created class if the feature is enabled - so the when a call is made to method I will return if it is not enabled. I could have a pointer to the object and then only call new if feature is enabled - but this means I will have to test before I call a method on it which would be potentially dangerous and not very readable. Would having an auto_ptr to the object improve things: auto_ptr<Feature> feature; Or am I still paying the cost of object invokation even though the object may\or may not be required. BTW - I don't think this is premeature optimisation - I just want to consider the possibilites.

• Port Win32 DLL hook to Linux

  - by peachykeen

  I have a program (NWShader) which hooks into a second program's OpenGL calls (NWN) to do post-processing effects and whatnot. NWShader was originally built for Windows, generally modern versions (win32), and uses both DLL exports (to get Windows to load it and grab some OpenGL functions) and Detours (to hook into other functions). I'm using the trick where Win will look in the current directory for any DLLs before checking the sysdir, so it loads mine. I have on DLL that redirects with this method: #pragma comment(linker, "/export:oldFunc=nwshader.newFunc) To send them to a different named function in my own DLL. I then do any processing and call the original function from the system DLL. I need to port NWShader to Linux (NWN exists in both flavors). As far as I can tell, what I need to make is a shared library (.so file). If this is preloaded before the NWN executable (I found a shell script to handle this), my functions will be called. The only problem is I need to call the original function (I would use various DLL dynamic loading methods for this, I think) and need to be able to do Detour-like hooking of internal functions. At the moment I'm building on Ubuntu 9.10 x64 (with the 32-bit compiler flags). I haven't been able to find much on Google to help with this, but I don't know exactly what the *nix community refers to it as. I can code C++, but I'm more used to Windows. Being OpenGL, the only part the needs modified to be compatible with Linux is the hooking code and the calls. Is there a simple and easy way to do this, or will it involve recreating Detours and dynamically loading the original function addresses?

• Entity Framework - Insert/Update new entity with child-entities

  - by Christina Mayers

  I have found many questions here on SO and articles all over the internet but none really tackled my problem. My model looks like this (I striped all non essential Properties): Everyday or so "Play" gets updated (via a XML-file containing the information). internal Play ParsePlayInfo(XDocument doc) { Play play = (from p in doc.Descendants("Play") select new Play { Theatre = new Theatre() { //Properties }, //Properties LastUpdate = DateTime.Now }).SingleOrDefault(); var actors = (from a in doc.XPathSelectElement(".//Play//Actors").Nodes() select new Lecturer() { //Properties }); var parts = (from p in doc.XPathSelectElement(".//Play//Parts").Nodes() select new Part() { //Properties }).ToList(); foreach (var item in parts) { play.Parts.Add(item); } var reviews = (from r in doc.XPathSelectElement(".//Play//Reviews").Nodes() select new Review { //Properties }).ToList(); for (int i = 0; i < reviews.Count(); i++) { PlayReviews pR = new PlayReviews() { Review = reviews[i], Play = play, //Properties }; play.PlayReviews.Add(pR); } return play; } If I add this "play" via Add() every Childobject of Play will be inserted - regardless if some exist already. Since I need to update existing entries I have to do something about that. As far as I can tell I have the following options: add/update the child entities in my PlayRepositories Add-Method restructure and rewrite ParsePlayInfo() so that get all the child entities first, add or update them and then create a new Play. The only problem I have here is that I wanted ParsePlayInfo() to be persistence ignorant, I could work around this by creating multiple parse methods (eg ParseActors() ) and assign them to play in my controller (I'm using ASP.net MVC) after everything was parsed and added Currently I am implementing option 1 - but it feels wrong. I'd appreciate it if someone could guide me in the right direction on this one.

• Symfony: How to hide form fields from display and then set values for them in the action class

  - by Tom

  I am fairly new to symfony and I have 2 fields relating to my table "Pages"; created_by and updated_by. These are related to the users table (sfGuardUser) as foreign keys. I want these to be hidden from the edit/new forms so I have set up the generator.yml file to not display these fields: form: display: General: [name, template_id] Meta: [meta_title, meta_description, meta_keywords] Now I need to set the fields on the save. I have been searching for how to do this all day and tried a hundred methods. The method I have got working is this, in the actions class: protected function processForm(sfWebRequest $request, sfForm $form) { $form_params = $request->getParameter($form->getName()); $form_params['updated_by'] = $this->getUser()->getGuardUser()->getId(); if ($form->getObject()->isNew()) $form_params['created_by'] = $this->getUser()->getGuardUser()->getId(); $form->bind($form_params, $request->getFiles($form->getName())); So this works. But I get the feeling that ideally I shouldnt be modifying the web request, but instead modifying the form/object directly. However I havent had any success with things like: $form->getObject()->setUpdatedBy($this->getUser()->getGuardUser()); If anyone could offer any advice on the best ways about solving this type of problem I would be very grateful. Thanks, Tom

• Can I use a specific model from within a behavior in CakePHP?

  - by Paul Willy

  I'm trying to write a behavior that will give my models access to a simple workflow engine I've devised. The workflow engine itself works as a CakePHP model, with workflow data stored in the database just as any other model data is stored. Basically what I want to do is have the behavior use the workflow model whenever an action is called on the base model. For example, if the edit() action is executed for Posts, then the Post (with the behavior attached) will trigger the workflow behavior with its own model name, action, and id as arguments (e.g. [Post, edit, 1]). Then the behavior will invoke the functionality of the Workflow model, which has a record for what to do when edit is run on Posts (e.g. send e-mail to users who are subscribed to that post) and will carry that out. My question is, what is the proper way to invoke model/controller methods from within the behavior? The model to be used from within the behavior will always be Workflow, but the behavior should be usable from basically any model (aside from Workflow itself). I know I could run SQL queries directly from the behavior, but of course this is not the Cake way :-) Or, am I going about this in the wrong way? I want to store a certain amount of logic in the database so that it is easily configurable by different users, and not have endless configuration checks within the model/controller logic itself so that workflow steps can be easily added/changed/removed in the future.

• Presenting an image cropping interface

  - by wkw

  I'm trying to engineer a UI for cropping images in iphone OS and suspect I'm going about things the hard way. My goal is pretty much what the Tapbots duo have done with Pastebot. In that app, they dim the source image but provide a movable and resizable cropping view and the image you're cropping is in a zoomable scrollview; when you resize or move the underlying image, the cropping view adjusts appropriately. I mocked up a composite image which will give a sense of the design I'm after, along with how I presently have my view hierarchy setup, viewable here The approach I've started with is the following: UIImageView with the image to crop is in a scrollview, a plain UIView with black fill and suitable transparency/alpha setting is added in front of the imageview. I then use a custom UIView which is a sibling to the scrollview at a higher level, which implements the drawRect: method and for the most part calls CGImageCreateWithImageInRect to get the portion of the image's bitmap that matches the position of the cropping view and draws that to the CGContext. in the viewcontroller I'm using the UIScrollViewDelegate methods to track scrolling and passing those changes to the custom cropping UIView so it stays in sync with the scroll contentOffset. That much is finally working. But trying to keep in sync as the scrollview zoomScale changes is when I figured I should ask for help. Looking for suggestions or guidance. My initial approach just seems like more work than is required. Could this be done with a masking layer in the ImageView? And if so, how would I setup the tracking for moving and resizing the cropping rect? My experience working with layers is non-nil, but very limited thus far.

• Auto-resolving a hostname in WCF Metadata Publishing

  - by Mike C

  I am running a self-hosted WCF service. In the service configuration, I am using localhost in my BaseAddresses that I hook my endpoints to. When trying to connect to an endpoint using the WCF test client, I have no problem connecting to the endpoint and getting the metadata using the machine's name. The problem that I run into is that the client that is generated from metadata uses localhost in the endpoint URLs it wants to connect to. I'm assuming that this is because localhost is the endpoint URL published by metadata. As a result, any calls to the methods on the service will fail since localhost on the calling machine isn't running the service. What I would like to figure out is if it is possible for the service metadata to publish the proper URL to a client depending on the client who is calling it. For example, if I was requesting the service metadata from a machine on the same network as the server the endpoint should be net.tcp://MYSERVER:1234/MyEndpoint. If I was requesting it from a machine outside the network, the URL should be net.tcp://MYSERVER.mydomain.com:1234/MyEndpoint. And obviously if the client was on the same machine, THEN the URL could be net.tcp://localhost:1234/MyEndpoint. Is this just a flaw in the default IMetadataExchange contract? Is there some reason the metadata needs to publish the information in a non-contextual way? Is there another way I should be configuring my BaseAddresses in order to get the functionality I want? Thanks, Mike

• Using JavaCC to infer semantics from a Composite tree

  - by Skice

  Hi all, I am programming (in Java) a very limited symbolic calculus library that manages polynomials, exponentials and expolinomials (sums of elements like "x^n * e^(c x)"). I want the library to be extensible in the sense of new analytic forms (trigonometric, etc.) or new kinds of operations (logarithm, domain transformations, etc.), so a Composite pattern that represent the syntactic structure of an expression, together with a bunch of Visitors for the operations, does the job quite well. My problem arise when I try to implement operations that depends on the semantics more than on the syntax of the Expression (like integrals, for instance: there are a lot of resolution methods for specific classes of functions, but these same classes can be represented with more than a single syntax). So I thought I need something to "parse" the Composite tree to infer its semantics in order to invoke the right integration method (if any). Someone pointed me to JavaCC, but all the examples I've seen deal only with string parsing; so, I don't know if I'm digging in the right direction. Some suggestions? (I hope to have been clear enough!)

• Adding exclusive filter for <static initializer> in findbugs

  - by MilanAleksic

  Hi all, I want my findbugs report not show the following error: DM_NUMBER_CTOR: Method invokes inefficient Number constructor; use static valueOf instead The problem is that this happens in groovy-generated code files, so I can't control the source code - that is why I want to exclude it and add it to my exclude filter. I do not want to add explicitly class (since I make API that many tools will use, I want my filter to be generic). I would not like to completely remove this bug from the report by type, I would really like to only exclude this bug from appearing if it happenned in "static initializer" methods. Any idea? I tried the filter below but no luck, maybe somebody has better idea? <Match> <Method name="~.*static initializer.*" /> <Bug pattern="DM_NUMBER_CTOR" /> </Match> Here is the "stacktrace" of FindBugs in that case: In class net.milanaleksic.cuc.tools.sound.SoundPlayerTool In method net.milanaleksic.cuc.tools.sound.SoundPlayerTool.() Called method new Long(long) Should call Long.valueOf(long) instead In SoundPlayerTool.groovy

• Loading from archive?

• Code Organization Connundrum: Web Project With Multiple Supporting DLLs?

  - by Code Sherpa

  Hi. I am trying to get a handle on the best practice for code organization within my project. I have looked around on the internet for good examples and, so far, I have seen examples of a web project with one or multiple supporting class libraries that it references or a web project with sub-folders that follow its namespace conventions. Assuming there is no right answer, this is what I currently have for code organization: MyProjectWeb This is my web site. I am referencing my class libraries here. MyProject.DLL As the base namespace, I am using this DLL for files that need to be generally consumable. For example, my class "Enums" that has all the enumerations in my project lives there. As does class MyProjectException for all exception handling. MyProject.IO.DLL This is a grouping of maybe 20 files that handle file upload and download (so far). MyProject.Utilities.DLL ALl my common classes and methods bunched up together in one generally consumable DLL. Each class follows a "XHelper" convention such as "SqlHelper, AuthHelper, SerializationHelper, and so on... MyProject.Web.DLL I am using this DLL as the main client interface. Right now, the majority of class files here are: 1) properties (such as School, Location, Account, Posts) 2) authorization stuff ( such as custom membership, custom role, & custom profile providers) My question is simply - does this seem logical? Also, how do I avoid having to cross reference DLLs from one project library to the next? For example, MyProject.Web.DLL uses code from MyProject.Utilities.DLL and MyProject.Utilities.DLL uses code from MyProject.DLL. Is this solved by clicking on properties and selecting "Dependencies"? I tried that but still don't seem to be accessing the namespaces of the assembly I have selected. Do I have to reference every assembly I need for each class library? Responses appreciated and thanks for your patience.

• The best way to implement drawing features like Keynote

  - by Shamseddine

  Hi all, I'm trying to make a little iPad tool's for drawing simple geometrical objects (rect, rounded rect, ellipse, star, ...). My goal is to make something very close to Keynote (drawing feature), i.e. let the user add a rect (for instance), resizing it and moving it. I want too the user can select many objects and move them together. I've thought about at least 3 differents ways to do that : Extends UIView for each object type, a class for Rect, another for Ellipse, ... With custom drawing method. Then add this view as subview of the global view. Extends CALayer for each object type, a class for Rect, another for Ellipse, ... With custom drawing method. Then add this layer as sublayer of the global view layer's. Extends NSObject for each object type, a class for Rect, another for Ellipse, ... With just a drawing method which will get as argument a CGContext and a Rect and draw directly the form in it. Those methods will be called by the drawing method of the global view. I'm aware that the two first ways come with functions to detect touch on each object, to add easily shadows,... but I'm afraid that they are a little too heavy ? That's why I thought about the last way, which it seems to be straight forward. Which way will be the more efficient ??? Or maybe I didn't thought another way ? Any help will be appreciated ;-) Thanks.

• Hidden div height

  - by fudgey

  Ok, I was going to answer someone's question here on SO about why their script wasn't working. They loaded content into a hidden div, then got the height so they could animate the wrapping div. But I always try to test the code I provide. So I made this demo to prove it to them. So, umm, have I entered the twilight zone or am I dreaming right now? pinches self OUCH! I tried that demo in Firefox, IE and Chrome and both methods return the same value. Firebug says zero! I rebooted my computer and I even changed the code a bit (removed the height function) and tried it with jQuery 1.3.2 and it still worked! I know hidden elements USED to return a zero value. Even this SO Answer is giving the advice I would have! So I guess my question is... did I miss something or are we giving bad advice?

• constructor function's object literal returns toString() method but no other method

  - by JohnMerlino

  I'm very confused with javascript methods defined in objects and the "this" keyword. In the below example, the toString() method is invoked when Mammal object instantiated: function Mammal(name){ this.name=name; this.toString = function(){ return '[Mammal "'+this.name+'"]'; } } var someAnimal = new Mammal('Mr. Biggles'); alert('someAnimal is '+someAnimal); Despite the fact that the toString() method is not invoked on the object someAnimal like this: alert('someAnimal is '+someAnimal.toString()); It still returns 'someAnimal is [Mammal "Mr. Biggles"]' . That doesn't make sense to me because the toString() function is not being called anywhere. Then to add even more confusion, if I change the toString() method to a method I make up such as random(): function Mammal(name){ this.name=name; this.random = function(){ return Math.floor(Math.random() * 15); } } var someAnimal = new Mammal('Mr. Biggles'); alert(someAnimal); It completely ignores the random method (despite the fact that it is defined the same way was the toString() method was) and returns: [object object] Another issue I'm having trouble understanding with inheritance is the value of "this". For example, in the below example function person(w,h){ width.width = w; width.height = h; } function man(w,h,s) { person.call(this, w, h); this.sex = s; } "this" keyword is being send to the person object clearly. However, does "this" refer to the subclass (man) or the super class (person) when the person object receives it? Thanks for clearing up any of the confusion I have with inheritance and object literals in javascript.

• Jrails and jquery-rails together?

  - by ecoologic

  I hope you forgive me if I'm a little confused about this. Jrails rewrites all the helper methods for rjs otherwise in prototype. Jquery-rails overrides rails.js (so I taught the rjs helpers as well, but I see it's not) and the rest of the libraries in jquery instead of prototype. Does it means that with just Jquery-rails I can't use rjs at all? Then do these gems work well together and let me completely forget prototype? Is there any disadvantage in using them together? I read some complaining about the fact that jrails uses jq 1.5 and now there is 1.8, but jquery-rails gives me the last version (is there retro compatibility?), but how will this affect my development (using both the gems together)? I mean have you got some examples of jquery-ui plugins I can't use or I could have problems with? Any help is appreciated. Don't get me wrong, I'm not against prototype, just I keep on having conflicts over conflicts using both of them, and I have to chose I pick Jquery.

• Connection

  - by pepersview

  Hello, I would like to ask you about NSURLConnection in objective-c for iPhone. I have one app that needs to connect to one webservice to receive data (about YouTube videos), Then I have all the things that I need to connect (Similar to Hello_Soap sample code in the web). But now, my problem is that I create a class (inherits from NSObject) named Connection and I have implemented the methods: didReceiveResponse, didReceiveData, didFailWithError and connectionDidFinishLoading. Also the method: -(void)Connect:(NSString *) soapMessage{ NSLog(soapMessage); NSURL *url = [NSURL URLWithString:@"http://....."]; NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url]; NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]]; [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"]; [theRequest setHTTPMethod:@"POST"]; [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if( theConnection ) { webData = [[NSMutableData data] retain]; } else { NSLog(@"theConnection is NULL"); } } But when from my AppDelegate I create one Connection object: Connection * connect = [[Connection alloc] Init:num]; //It's only one param to test. [connect Connect:method.soapMessage]; And I call this method, when this finishes, it doesn't continue calling didReceiveResponse, didReceiveData, didFailWithError or connectionDidFinishLoading. I'm trying to do this but I can't for the moment. The thing I would like to do is to be able to call this class "Connection" each time that I want to receive data (after that to be parsed and displayed in UITableViews). Thank you.

• Which view will be resolved, code from spring's docs

  - by Blankman

  So when you go to /appointments the get() action is called, so then would the view be get.jsp (assuming you are using .jsp, and assuming you are mapping action names to views)? And what about the getnewform? It seems to be returning an object? Is that basically passed into the view? @Controller @RequestMapping("/appointments") public class AppointmentsController { private final AppointmentBook appointmentBook; @Autowired public AppointmentsController(AppointmentBook appointmentBook) { this.appointmentBook = appointmentBook; } @RequestMapping(method = RequestMethod.GET) public Map<String, Appointment> get() { return appointmentBook.getAppointmentsForToday(); } @RequestMapping(value="/{day}", method = RequestMethod.GET) public Map<String, Appointment> getForDay(@PathVariable @DateTimeFormat(iso=ISO.DATE) Date day, Model model) { return appointmentBook.getAppointmentsForDay(day); } @RequestMapping(value="/new", method = RequestMethod.GET) public AppointmentForm getNewForm() { return new AppointmentForm(); } @RequestMapping(method = RequestMethod.POST) public String add(@Valid AppointmentForm appointment, BindingResult result) { if (result.hasErrors()) { return "appointments/new"; } appointmentBook.addAppointment(appointment); return "redirect:/appointments"; } } In the example, the @RequestMapping is used in a number of places. The first usage is on the type (class) level, which indicates that all handling methods on this controller are relative to the /appointments path. The get() method has a further @RequestMapping refinement: it only accepts GET requests, meaning that an HTTP GET for /appointments invokes this method. The post() has a similar refinement, and the getNewForm() combines the definition of HTTP method and path into one, so that GET requests for appointments/new are handled by that method.

• Reducing Time Complexity in Java

  - by Koeneuze

  Right, this is from an older exam which i'm using to prepare my own exam in january. We are given the following method: public static void Oorspronkelijk() { String bs = "Dit is een boodschap aan de wereld"; int max = -1; char let = '*'; for (int i=0;i<bs.length();i++) { int tel = 1; for (int j=i+1;j<bs.length();j++) { if (bs.charAt(j) == bs.charAt(i)) tel++; } if (tel > max) { max = tel; let = bs.charAt(i); } } System.out.println(max + " keer " + let); } The questions are: what is the output? - Since the code is just an algorithm to determine the most occuring character, the output is "6 keer " (6 times space) What is the time complexity of this code? Fairly sure it's O(n²), unless someone thinks otherwise? Can you reduce the time complexity, and if so, how? Well, you can. I've received some help already and managed to get the following code: public static void Nieuw() { String bs = "Dit is een boodschap aan de wereld"; HashMap<Character, Integer> letters = new HashMap<Character, Integer>(); char max = bs.charAt(0); for (int i=0;i<bs.length();i++) { char let = bs.charAt(i); if(!letters.containsKey(let)) { letters.put(let,0); } int tel = letters.get(let)+1; letters.put(let,tel); if(letters.get(max)<tel) { max = let; } } System.out.println(letters.get(max) + " keer " + max); } However, I'm uncertain of the time complexity of this new code: Is it O(n) because you only use one for-loop, or does the fact we require the use of the HashMap's get methods make it O(n log n) ? And if someone knows an even better way of reducing the time complexity, please do tell! :)

• what is the point of heterogenous arrays?

  - by aharon

  I know that more-dynamic-than-Java languages, like Python and Ruby, often allow you to place objects of mixed types in arrays, like so: ["hello", 120, ["world"]] What I don't understand is why you would ever use a feature like this. If I want to store heterogenous data in Java, I'll usually create an object for it. For example, say a User has int ID and String name. While I see that in Python/Ruby/PHP you could do something like this: [["John Smith", 000], ["Smith John", 001], ...] this seems a bit less safe/OO than creating a class User with attributes ID and name and then having your array: [<User: name="John Smith", id=000>, <User: name="Smith John", id=001>, ...] where those <User ...> things represent User objects. Is there reason to use the former over the latter in languages that support it? Or is there some bigger reason to use heterogenous arrays? N.B. I am not talking about arrays that include different objects that all implement the same interface or inherit from the same parent, e.g.: class Square extends Shape class Triangle extends Shape [new Square(), new Triangle()] because that is, to the programmer at least, still a homogenous array as you'll be doing the same thing with each shape (e.g., calling the draw() method), only the methods commonly defined between the two.

• Dynamic checkboxlist

  - by Steve

  Hi, I am currently building a dynamic url tab system that user can say what urls they want to be displayed on a tabpage control. In the database i have the following columns. userID, int URLName var Enabled bit I am pulling the data back ok but what i am trying do is populate a checkbox list with the urlname and its status on a user options page so they can say what tabs they want displayed. I have wrote the following methods to get the urls and create the checkboxes however i keep getting the following error. ex = {"InvalidArgument=Value of '1' is not valid for 'index'.\r\nParameter name: index"} It reads the first row ok but when it hits the 2nd row that is being returned i get that error. Has anyone got any ideas? Thanks private void GetUserURLS() { db.initiateCommand("[Settings].[LoadAllUserURLS]", CommandType.StoredProcedure); sqlp = db.addParameter("@UserID", _UserID, SqlDbType.Int, ParameterDirection.Input); sqlp = db.addParameter("@spErrorID", DBNull.Value, SqlDbType.Int, ParameterDirection.InputOutput); db.executeCommand(); CreateCheckBoxes(db.getTable(0).Rows); db.releaseCommand(); } private void CreateCheckBoxes(DataRowCollection rows) { try { int i = 0; foreach (DataRow row in rows) { //Gets the url name and path when the status is enabled. The status of Enabled / Disabled is setup in the users option page string URLName = row["URLName"].ToString(); bool enabled = Convert.ToBoolean(row["Enabled"]); CheckedListBox CB = new CheckedListBox(); CB.Items.Insert(i, URLName); CB.Tag = "CB" + i.ToString(); checkedListBox1.Items.Add(CB); i++; } } catch (Exception ex) { //Log error Functionality func = new Functionality(); func.LogError(ex); //Error message the user will see string FriendlyError = "There has been populating checkboxes with the urls - A notification has been sent to development"; Classes.ShowMessageBox.MsgBox(FriendlyError, "There has been an Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } }

• How to get notified about changes on SharePoint groups.

  - by Flo

  Hi, I'm actual looking for a way to get notified about any changes on a SharePoint group. First I though I would be able to this by attaching a event handler to some kind of group list. But unfortunately there are no such list representing SharePoint groups. My second attempt was to bind a event handler to the content type SharePointGroup but this didn't work either. So are there any other options to get notified about events on a SharePoint group? Bye, Flo EDIT: Thanks for the reply so far. I forgot to mention that I've already googled and read about the user information list. Sorry. First I found a forum entry where they post the relative URL to the user information list (_catalogs/users/simple.aspx). When I'm using this link to see the list,it only contains users and no groups. I don't know but perhaps this link does some filtering on the list. The other information I found about in several blog and forum posts was that a event handler attached to the user information list are not fired up on an events. I have to admit after reading that it doesn't work so many times and even on MSDN (http://msdn.microsoft.com/en-us/library/aa979520.aspx), I didn't try it on my own. The problem attaching the event handler to the content type wasn't the attaching thing, the handler simply didn't get fired when I for example changed a group name or deleted a user from the group. I don't have an idea why the handler doesn't get called I pretty sure I implemented the right methods and attached them to the right events. Any other suggestions how to get informed about changes on SharePoint groups?

• Is it possible to add JPA annotation to superclass instance variables?

  - by Kristofer Borgstrom

  Hi, I am creating entities that are the same for two different tables. In order do table mappings etc. different for the two entities but only have the rest of the code in one place - an abstract superclass. The best thing would be to be able to annotate generic stuff such as column names (since the will be identical) in the super class but that does not work because JPA annotations are not inherited by child classes. Here is an example: public abstract class MyAbstractEntity { @Column(name="PROPERTY") //This will not be inherited and is therefore useless here protected String property; public String getProperty() { return this.property; } //setters, hashCode, equals etc. methods } Which I would like to inherit and only specify the child-specific stuff, like annotations: @Entity @Table(name="MY_ENTITY_TABLE") public class MyEntity extends MyAbstractEntity { //This will not work since this field does not override the super class field, thus the setters and getters break. @Column(name="PROPERTY") protected String property; } Any ideas or will I have to create fields, getters and setters in the child classes? Thanks, Kris
