• Is it considered bad practice to have ViewModel objects hold the Dispatcher?

  - by stiank81

  My WPF application is structured using the MVVM pattern. The ViewModels will communicate asynchronously with a server, and when the requested data is returned a callback in the ViewModel is triggered, and it will do something with this data. This will run on a thread which is not the UI Thread. Sometimes these callbacks involve work that needs to be done on the UI thread, so I need the Dispatcher. This might be things such as: Adding data to an ObservableCollection Trigger Prism commands that will set something to be displayed in the GUI Creating WPF objects of some kind. I try to avoid the latter, but the two first points here I find to be reasonable things for ViewModels to do. So; is it okay to have ViewModels hold the Dispatcher to be able to Invoke commands for the UI thread? Or is this considered bad practice? And why?

• Save NSCache Contents to Disk

  - by Cory Imdieke

  I'm writing an app that needs to keep an in-memory cache of a bunch of objects, but that doesn't get out of hand so I'm planning on using NSCache to store it all. Looks like it will take care of purging and such for me, which is fantastic. I'd also like to persist the cache between launches, so I need to write the cache data to disk. Is there an easy way to save the NSCache contents to a plist or something? Are there perhaps better ways to accomplish this using something other than NSCache? This app will be on the iPhone, so I'll need only classes that are available in iOS 4+ and not just OS X. Thanks!

• Access the camera of a Smartphone using libGDX

  - by PH-zero

  I searched the web, browsed through the libGDX wiki, but without success. My Question: Is there a way, to access the camera of smartphones, let the user take a photo, and then store the image in a Texture-instance? I could imagin something like this: @Override public void onCamTrigger(){ ApplicationType appType = Gdx.app.getType(); switch (appType) { case Android: case iOS: Texture someTexture = new Texture(Gdx.input.getCamera().getImage()); //do something with the Texture instance... someTexture.dispose(); break; default: break; } } Of course this is pure fiction! I know that there's a lot more to this like opening the camera, displaying it, then take a photo etc. . But is there a convenience method like this? If so, how does it work? On Android, i think i could implement it without using any convenience methods offered by libGDX, but i have no idea on how this works on iOS =/

• array loop not working correctly? c++

  - by igor

  Trying to count how many elements within the array are not equal to 0, is something set up wrong? I'd like to check all values in the array (it's a sudoku board) and then when all elements are "full" I need to return true. Is something off? bool boardFull(const Square board[BOARD_SIZE][BOARD_SIZE]) { int totalCount=0; for (int index1 = 0; index1 < BOARD_SIZE; index1++) for (int index2 = 0; index2 < BOARD_SIZE; index2++){ if(board[index1][index2].number!=0) totalCount++; } if(totalCount=81) return true; else return false;

• How do i get a directory listing for a folder on the web?

  - by JimDel

  How do I get a directory listing for a folder on the web? I'm looking to download a group of small files from a folder on the web. I can do it easily with a a single file but I'm not sure how to do it for multiple files. If there was something similar to the code below but for a folder on the web I think I can do it. private void button1_Click(object sender, EventArgs e) { DirectoryInfo di = new DirectoryInfo("c:/myFolder"); FileInfo[] rgFiles = di.GetFiles("*.*"); foreach (FileInfo fi in rgFiles) { //Do Something with each of them } } Thanks

• Using a message class static method taking in an action to wrap Try/Catch

  - by Chris Marisic

  I have a Result object that lets me pass around a List of event messages and I can check whether an action was successful or not. I've realized I've written this code in alot of places Result result; try { //Do Something ... //New result is automatically a success for not having any errors in it result = new Result(); } catch (Exception exception) { //Extension method that returns a Result from the exception result = exception.ToResult(); } if(result.Success) .... What I'm considering is replacing this usage with public static Result CatchException(Action action) { try { action(); return new Result(); } catch (Exception exception) { return exception.ToResult(); } } And then use it like var result = Result.CatchException(() => _model.Save(something)); Does anyone feel there's anything wrong with this or that I'm trading reusability for obscurity?

• Sorting 2 arrays that have been added together

  - by tyler

  In my app, users can create galleries that their work may or may not be in. Users have and belong to many Galleries, and each gallery has a 'creator' that is designated by the gallery's user_id field. So to get the 5 latest galleries a user is in, I can do something like: included_in = @user.galleries.order('created_at DESC').uniq.first(5) # SELECT DISTINCT "galleries".* FROM "galleries" INNER JOIN "galleries_users" ON "galleries"."id" = "galleries_users"."gallery_id" WHERE "galleries_users"."user_id" = 10 ORDER BY created_at DESC LIMIT 5 and to get the 5 latest galleries they've created, I can do: created = Gallery.where(user_id: id).order('created_at DESC').uniq.first(5) # SELECT DISTINCT "galleries".* FROM "galleries" WHERE "galleries"."user_id" = 10 ORDER BY created_at DESC LIMIT 5 I want to display these two together, so that it's the 5 latest galleries that they've created OR they're in. Something like the equivalent of: (included_in + created).order('created_at DESC').uniq.first(5) Does anyone know how to construct an efficient query or post-query loop that does this?

• Unbind Events with JQuery: Does it work with events setup in HTML?

  - by Abs

  Hello all, I have a few onclick and on mouseover events in my html generated by PHP, something like this: <div onmouseover="fave('heart_<?php echo $row['id']; ?>';" class="heart"><a href=""></a></div> I wish to make use of unbind on the mouseover but it hasn't worked when I tried this: $('#'+ id).unbind('mouseover'); So I am guessing unbind will only work with events created by JQuery? Is there something else I can try? Btw, I can't move my events to a separate js file as each id is unique and. Thanks all

• VisualStudio: Toggle Archive Attribute When Saving File?

  - by John Dibling

  We use Tortoise CVS in out shop, but in my last job we used Visual SourceSafe. VSS is generally a pile, but it did have one nice feature. You could right-click on a branch and ask it for a list of all the files you had checked-out. As far as I can tell there is no similar feature in CVS. So what I'm looking for is some kind of VS plusgin that will automatically reset (turn off) the archive attribute when saving a file. Then I can recursively dir to find the files I have checked-out. Does anyone know of a VS plugin or something I can do to get this behavior? Or is there something else I can do in CVS to get my ultimately desired result?

• Search in big text log files

  - by 0xFF

  Hi, let's say you have an game server which creating text log files of gamers actions, and from time to time you need to lookup something in those logs files (like investigating an scam or loosing an item). Just for example you have 100 files and each file have size between 20MB and 50MB - How you would search them quickly? What I have already tried to do is create several threads and each invidual thread will map his own file to memory (let say memory should not be problem if it not exceed 500MB of ram) perform search here, result was something around 1 second per file : File:a26.log - read in: 0.891, lines: 625282, matches: 78848 Is there better way how to do that ? - because it seems to me kinda slow. thanks. (java was used for this case)

• Architecture for analysing search result impressions/clicks to improve future searches

  - by Hais

  We have a large database of items (10m+) stored in MySQL and intend to implement search on metadata on these items, taking advantage of something like Sphinx. The dataset will be changing slightly on a daily basis so Sphinx will be re-indexing daily. However we want the algorithm to self-learn and improve search results by analysing impression and click data so that we provide better results for our customers on that search term, and possibly other similar search terms too. I've been reading up on Hadoop and it seems like it has the potential to crunch all this data, although I'm still unsure how to approach it. Amazon has tutorials for compiling impression vs click data using MapReduce but I can't see how to get this data in a useable format. My idea is that when a search term comes in I query Sphinx to get all the matching items from the dataset, then query the analytics (compiled on an hourly basis or similar) so that we know the most popular items for that search term, then cache the final results using something like Memcached, Membase or similar. Am I along the right lines here?

• How to delay user login until RunOnce is completed? [Win XP]

  - by Shaitan00

  Currently I have an application that runs at startup when a user log's in to the account (administrative), as well as something under HKLM...\Run which is also executed - but I need to run something once and BEFORE both these things are executed. My solution was to use HKLM...\RunOnce which is executed before the HKLM...\Run but the task can take 30-45 seconds which gives enough time for the user Startup to be executed and launch the application prematurely. I thought of maybe including a SLEEP but RunOnce doesn't block the user account load... Then I considered the group policies but they do not have a RunOnce equivalent that I can use... Also I am not sure if Group Policy is run at the right time (never used it before). Is there anyway to make my RunOnce delay the account startup of my application, or a better place where I can execute it before both HKLM...\Run and user Startup? Or any recommended alternatives? Any ideas or help would be much appreciated... Thanks,

• A lot to merge after creating a new branch in SVN

  - by homaxto

  We have recently made a new branch, let us call it rel3.6, which was based on the last release named rel3.5. Work has started on rel3.6, and meanwhile some bugs has been fixed on rel3.5 which now is used for a service pack to be released soon. Today I wanted to merge those bugs from rel3.5 to rel3.6, so I fired up SmartSVN. Standing in the rel3.6 branch i chosed\ to merge with rel3.5 and selected to browse for a revision range. To my surprise there was a huge list of changes even though I checked "Stop on copy" and only showing mergeable revisions. Most of them where dated back before the creation of rel3.6. I did not expect to find anything from before rel3.5 was created. If I make a merge, the only thing I get are changes and conflicts to directory properties. Have I misunderstood something, or is it possible that something was done wrong when creating the branch?

• Facebook "->api" permissions

  - by Matthieu Marcé

  I have trouble using Facebook auth on my website... I'm using the PHP Sdk and I don't understand why I can use some functions like "getLoginUrl"/"getLoginStatusUrl"/"getUser" (with right answers : the facebook session is started, i get the user's facebook ID) and when I want to use something like $me = $facebook->api("/me/permissions"); or just $me = $facebook->api("/me"); there's always an exception and nothing works ... I guess it has something to do with permissions or token maybe, but I don't know what. When the user sign up on my website, I ask permissions I need with this scope : "email,user_about_me,user_location,read_friendlists,publish_stream" A clue that the permissions seem to be ok is that when the exception occures, I ask the user to sign in again (facebook connect) and no window appears as if everything's ok, but still, the page is reloaded and the exception appears again and again... Please help, Thank you !

• git-svn clone checkouts wrong repo?

  - by hyperboreean

  So I am trying to switch to git, by using git-svn. I am having a svn repo called myrepo from which I want to clone just the project called myproject. The thing is that by running the following command: git svn clone path-to-repo/myrepo/myproject --stdlayout --prefix=svn myproject the whole repo myrepo is cloned rather than just myproject. I tried using -T, -t, -b as well to let git know about the layout of the project, but without any success. I always get the following output: Using higher level of URL: path-to-repo/myrepo/myproject => path-to-repo/myrepo and tries to clone that one. Am I doing something wrong? It might be that the svn repo layout could be broken or git incompatible ?

• Use nested static class as ActionListener for the Outer class

  - by Digvijay Yadav

  I want to use an nested static class as an actionListener for the enclosing class's GUI elements. I did something like this: public class OuterClass { public static void myImplementation() { OuterClass.StartupHandler startupHandler = new OuterClass.StartupHandler(); exitMenuItem.addActionListener(startupHandler); // error Line } public static class StartupHandler implements ActionListener { @Override public void actionPerformed(ActionEvent e) { //throw new UnsupportedOperationException("Not supported yet."); if (e.getSource() == exitMenuItem) { System.exit(1); } else if (e.getSource() == helpMenuItem) { // show help menu } } } } But when I invoke this code I get the NullPointerException at the //error Line. Is this the right method to do do this or there is something I did am missing?

• How do I get every nth row in a table, or how do I break up a subset of a table into sets or rows of

  - by Jherico

  I have a table of heterogeneous pieces of data identified by a primary key (ID) and a type identifier (TYPE_ID). I would like to be able to perform a query that returns me a set of ranges for a given type broken into even page sizes. For instance, if there are 10,000 records of type '1' and I specify a page size of 1000, I want 10 pairs of numbers back representing values I can use in a BETWEEN clause in subsequent queries to query the DB 1000 records at a time. My initial attempt was something like this select id, rownum from CONTENT_TABLE where type_id = ? and mod(rownum, ?) = 0 But this doesn't work.

• Hosting Private Git repos on my own server?

  - by Stoic

  Hey, I am looking for a way to host private git repos on my own server. I am using Github for Open source projects of mine, but I would prefer to use my own server for storing private git repos. Can someone suggest me on which script should I be using for this purpose. Trac is not what I am looking for, though. I want something that is, preferably PHP based solution (just optional) and esp. something that has an easier UI. Any help is appreciated here.

• How to pass a function to a function?

  - by ShaChris23

  Suppose I have a class with 2 static functions: class CommandHandler { public: static void command_one(Item); static void command_two(Item); }; I have a problem DRY problem where I have 2 functions that have the exact same code for every single line, except for the function that it calls: void CommandOne_User() { // some code A CommandHandler::command_one(item); // some code B } void CommandTwo_User() { // some code A CommandHandler::command_two(item); // some code B } I would like to remove duplication, and, ideally, do something like this: void CommandOne_User() { Function func = CommandHandler::command_one(); Refactored_CommandUser(func); } void CommandTwo_User() { Function func = CommandHandler::command_one(); Refactored_CommandUser(func); } void Refactored_CommandUser(Function func) { // some code A func(item); } I have access to Qt, but not Boost. Could someone help suggest a way on how I can refactor something like this?

• Overload and hide methods in Java

  - by Marco

  Hi, i have an abstract class BaseClass with a public insert() method: public abstract class BaseClass { public void insert(Object object) { // Do something } } which is extended by many other classes. For some of those classes, however, the insert() method must have additional parameters, so that they instead of overriding it I overload the method of the base class with the parameters required, for example: public class SampleClass extends BaseClass { public void insert(Object object, Long param){ // Do Something } } Now, if i instantiate the SampleClass class, i have two insert() methods: SampleClass sampleClass = new SampleClass(); sampleClass.insert(Object object); sampleClass.insert(Object object, Long param); what i'd like to do is to hide the insert() method defined in the base class, so that just the overload would be visible: SampleClass sampleClass = new SampleClass(); sampleClass.insert(Object object, Long param); Could this be done in OOP?

• jquery animation problem using stop

  - by Flanders

  Hi! When running a Jquery animation like slideDown(), it looks like a number of element-specific css properties is set to be updated at a specific interval and when the animation is complete these properties are unset and the display property is simply set to auto or whatever. At least in firebug you can't see those temporary properties any more. The problem I've encountered is the scenario where we stop the slide down with stop(). The element is then left with the current temporary css values. Which is fine because it has to, but let us say that I stoped the slidedown because I have decided to slide it back up again a bit prematurely. It would look something like this: $(this).slideDown(2000) //The below events is not in queue but will rather start execute almost simultaneously as the above line. (dont remember the exact syntax) $(this).delay(1000).stop().slideUp(2000) The above code might not make much sense, but the point is: After 1 second of sliding down the animation is stopped and it starts to slide back up. Works like a charm. BUT!!! And here is the problem. Once it it has slid back up the elements css properties are reset to the exact values it had 1000ms into the slideDown() animation (when stop() was called). If we now try to run the following: $(this).slideDown(2000) It will slide down to the very point the prior slideDown was aborted and not further at half the speed (since it uses the same time for approximately half the height). This is because the css properties were saved as I see it. But it is not especially wished for. Of course I want it to slide all the way down this time. Due to UI interaction that is hard to predict everything might soon break. The longer animations we use increases the risk of something like this happening. Is this to be considered a bug, or am I doing something wrong? Or maybe it's just a feature that is not supported? I guess I can use a callback function to reset the css properties, but depending on the animation used, different css properties are used to render it, and covering your back would result in quite a not-so-fancy solution.

• How Does the VS 2010 web.config work?

  - by chobo2

  Hi I am just wondering in VS2010 the web.config is broken up into web.config web.debug.config web.release.config So from what I gathered is the web.config is just like the master template. So I am guessing in my debug I could put things like my local database where in my release one I would put my server database. Now how does it know when to use the release version or debug version? I also here that you can have more than 2. How does that work?
