  • C# programatically using a string as object name when instantiating an object

    - by emk
    This is a contrived example, but lets say I have declared objects: CustomObj fooObj; CustomObj barObj; CustomObj bazObj; And I have an string array: string[] stringarray = new string[] {"foo","bar","baz"}; How can I programatically access and instantiate those objects using the string array, iterating using something like a foreach: foreach (string i in stringarray) { `i`Obj = new CustomObj(i); } Hope the idea I'm trying to get across is clear. Is this possible in C#? Thanks in advance.

  • Which LINQ query is more effective?

    - by Danny Chen
    I have a huge IEnumerable(suppose the name is myItems), which way is more effective? Solution 1: Filter it first then ForEach. Array.ForEach(myItems.Where(FILTER-IT-HERE).ToArray(),MY-ACTION); Solution 2: Do RETURN in MY-ACTION if the item is not up to the mustard. Array.ForEach(myItems.ToArray(),MY-ACTION-WITH-FILTER); Is one of them always better than another? Or any other good suggestions? Thanks in advance.

    - by Chocho
    i have a form that has a multiple select drop down. a user can select more than one options in the select. the name of the select is array[]; using php i implode(",",$array) in mysql db, it stores the field as a text in this format "places"= "new york, toronto, london" when i want to display these fields i explode the commas. i am trying to run a report to display the places. here is my select: "select * from mytable where db.places .. userSelectedPlaces" how can i check toronto in lists of "places" that user selected? note "places" in the db might be either just "toronto" or it might be comma separated lists of places like "ny, toronto, london, paris, etc".

  • YII Mail Generate unwanted ascii character in HTML mail

    - by CedSha
    I use YII-Mail just by copying the sample but I always get some ascii charcters in my generated links Where they come from and how to avoid them ? $message = new YiiMailMessage; $message->view = 'mail'; $message->setBody(array('model'=>$model), 'text/html'); $message->subject = Yii::t('tr','my subject'); $message->addTo('[email protected]'); $message->from = '[email protected]'; Yii::app()->mail->send($message); and in view file 'mail' <h1><?php echo(Yii::t('tr','This is HTML mail')); ?></h1> <?php echo CHtml::link('Mylink', array('controller/view', 'id'=>$model->id)); ?> The resulted email source looks like this <h1>This is HTML mail</h1> <a href=3D"/testdrive/index.php?r=3D ....

  • Google Cloud Messaging (GCM) for turn-based mobile multiplayer server?

    - by Chris
    I'm designing a multiplayer turn-based game for Android (over 3g). I'm thinking the clients will send data to a central server over a socket or http, and receive data via GCM push messaging. I'd like to know if anyone has practical experience with GCM for pushing 'real-time' turn data to game clients. What kind of performance and limitations does it have? I'm also considering using a RESTful approach with GAE or Amazon EC2. Any advice about these approaches is appreciated.

  • Apple Cinema Display 23" and grub

    - by Joshua Pruitt
    As per the title, I'm running my display on an older 23" Apple Cinema Display (because I still love it, darn it). I'm pushing it with an ATI Radeon DVI dual-link PCIe card. It works just fine, except GRUB doesn't seem able to push out the 1920x1200 pixel resolution needed in order to show me a boot menu! So..., I keep a smaller second monitor connected as the primary display so that I can see the boot menu and boot the system (I don't use that display once booted). This is a goofy work-around, and I'd like to just use my single display exclusively to boot the machine. I found some grub codes for higher resolutions, but not for 1920x1200. Is it capable of this? Did I just miss it? Thanks in advance!!!

  • How to configure Google Analytics experiments manually

    - by John
    I wish to run multivariate tests on an e-commerce site that run across all product pages. I will be setting and deciding the variations myself all I need to do is track the results in GA. I think may be possible (although only A/B testing is available via the GA UI): https://developers.google.com/analytics/devguides/platform/features/experiments#serving-framework EXTERNAL – You will choose variations, handle experiment optimization, and only report the chosen variation to Google Analytics. For example, this should be used by 3rd-party optimization platforms that want to integrate with Google Analytics for reporting purposes. In this case, the Google Analytics statistical engine will not run. However how do I configure this and push the data to GA in my page?

  • ASP -response-flush-flushes-partial-data

    - by Anshu
    I am developing a web app with an ASP server side and I use an iframe for data push. An ASP handler flushes every once in a while some javascript to the iframe: context.Response.Write("<script language='javascript'>top.update('lala');</script>"); context.Response.Flush(); My problem is that sometimes, when I receive the data, I don't get the full text. For example I will receive this : update('lala'); One workaround I have is to have a thread flushing '..........' every 500ms. (Then I will receive script...... which will complete my javascript.) However I am sure there must be a way to have Response.Flush() sending the whole chunk of data. Does someone have an idea on how to use properly Response.Flush() ? Thank you!

  • Forking project on Github etiquette

    - by Mike Wills
    There is a project on Github that I mostly like and want to use. There are a few things I want to do differently/remove that doesn't make sense for what I want/need. Also I want to add a few things as well. As I understand it, I should fork the project and I can make whatever changes I want and push back to my fork. From there, I also want to occasionally pull into my fork the changes from the original project so I get the latest bug fixes/features. Am I off-base of how I think it should work? How would bring in the changes from the original project?

  • Saving jQuery UI Sortable's order to Backbone.js Collection

    - by VirtuosiMedia
    I have a Backbone.js collection that I would like to be able to sort using jQuery UI's Sortable. Nothing fancy, I just have a list that I would like to be able to sort. The problem is that I'm not sure how to get the current order of items after being sorted and communicate that to the collection. Sortable can serialize itself, but that won't give me the model data I need to give to the collection. Ideally, I'd like to be able to just get an array of the current order of the models in the collection and use the reset method for the collection, but I'm not sure how to get the current order. Please share any ideas or examples for getting an array with the current model order.

  • Ubuntu One stuck and doing nothing - help!!!

    - by Laurence Nagel
    Ubuntu One has worked fine for me for several weeks and I now have 8.2 GB of files in the clouds. Then, last night, Ubuntu One stopped working. When I fire up System-Preferences-Ubuntu One, It tells me that I have 8.2 GB stored (13.2 %) and the my status in Unknown. I've tried Restart to no avail. I even tried Remove, followed by clearing the password ring and starting over. Still nothing. I've run out of buttons to push.

    - by Chris Hoffman
    Windows 8’s new touch-first Modern interface includes quite a few apps. Before you start looking at the Windows Store to find new apps, take a look at the included apps and what they can do. These apps share a few things in common. They all have a minimal feel that emphasizes content, most have support for live tiles that show updated information on the Start screen, and most push Microsoft’s online services.

  • Easiest way of checking if a string consists of unique characters?

    - by serg555
    I need to check in Java if a word consists of unique letters (case insensitive). As straight solution is boring, I came up with: For every char in a string check if indexOf(char) == lastIndexOf(char). Add all chars to HashSet and check if set size == string length. Convert a string to a char array, sort it alphabetically, loop through array elements and check if c[i] == c[i+1]. Currently I like #2 the most, seems like the easiest way. Any other interesting solutions?

  • How to use different php.ini files for different VirtualHosts?

    - by gsingh2011
    I have my site and it's staging subdomain running on the same CentOS machine running apache. The subdomain is created using a VirtualHost, and I use it to find any bugs before I push to production. I want the php.ini file for the staging VirtualHost to be a development one, and the production site will use a production php.ini. How can I configure apache to use different php.ini files? I don't want to use php_value/php_flag for everything, I'd rather just use the php.ini file I already have available. I've tried creating an .htaccess file that looks like this, SetEnv PHPRC /path/to/php.ini/directory This has no effect, as phpinfo() tells me it's still using /etc/php.ini. I've also tried setting PHPIniDir for both virtual hosts (www and staging) and it complains about seeing the directive twice.

  • Finding backedges in a graph, with special conditions.

    - by Morteza M.
    There is a vertex v, such that from the subtree rooted at v, there are at least two backedges to proper ancestors of v. The problem is finding whether such backedges exist or not ( finding v is not important at all). I run DFS algorithm, I can find backedges and save them in an array. I know which backedges in this array belong to a common tree. but I have problem on matching this condition in O(E) time. can anyone help me with that?

  • jQuery Resizable() UI Problem

    - by OneNerd
    In general, resizable() works fine. Here is where I am getting into an issue. I have a div that contains some resizable items that work fine (resizable() applied to them at some point). user can save items for later view (the innerHTML of the div gets saved into a JavaScript array, then div gets cleared so they can do something else) When items get placed back onto div (from array) -- I do a $('#divname').append(arrayname[i]); -- items are no longer resizable (although visually they have the resizable classes/handle on them) Here is what I have tried so far (none of which have worked): After append() line, I re-initialize the resizable -- $('#items').resizable(); After append() line, remove then re-add resizable -- $('#items').resizable('destroy').resizable(); Any help is appreciated - thanks.

  • Unexpected output from Bubblesort program with MSVC vs TCC

    - by Sujith S Pillai
    One of my friends sent this code to me, saying it doesn't work as expected: #include<stdio.h> void main() { int a [10] ={23, 100, 20, 30, 25, 45, 40, 55, 43, 42}; int sizeOfInput = sizeof(a)/sizeof(int); int b, outer, inner, c; printf("Size is : %d \n", sizeOfInput); printf("Values before bubble sort are : \n"); for ( b = 0; b &lt; sizeOfInput; b++) printf("%d\n", a[b]); printf("End of values before bubble sort... \n"); for ( outer = sizeOfInput; outer &gt; 0; outer-- ) { for ( inner = 0 ; inner &lt; outer ; inner++) { printf ( "Comparing positions: %d and %d\n",inner,inner+1); if ( a[inner] &gt; a[inner + 1] ) { int tmp = a[inner]; a[inner] = a [inner+1]; a[inner+1] = tmp; } } printf ( "Bubble sort total array size after inner loop is %d :\n",sizeOfInput); printf ( "Bubble sort sizeOfInput after inner loop is %d :\n",sizeOfInput); } printf ( "Bubble sort total array size at the end is %d :\n",sizeOfInput); for ( c = 0 ; c &lt; sizeOfInput; c++) printf("Element: %d\n", a[c]); } I am using Micosoft Visual Studio Command Line Tool for compiling this on a Windows XP machine. cl /EHsc bubblesort01.c My friend gets the correct output on a dinosaur machine (code is compiled using TCC there). My output is unexpected. The array mysteriously grows in size, in between. If you change the code so that the variable sizeOfInput is changed to sizeOfInputt, it gives the expected results! A search done at Microsoft Visual C++ Developer Center doesn't give any results for "sizeOfInput". I am not a C/C++ expert, and am curious to find out why this happens - any C/C++ experts who can "shed some light" on this? Unrelated note: I seriously thought of rewriting the whole code to use quicksort or merge sort before posting it here. But, after all, it is not Stooge sort... Edit: I know the code is not correct (it reads beyond the last element), but I am curious why the variable name makes a difference.

  • How to extract text using regex in Actionscript?

    In the HTML below: <a href="link1.php">1</a><a href="link2.php">2</a><a href="link3.php">3</a> How do I extract link1.php,link2.php,link3.php and push them into an array using regex? (There could be N number of <a> tags in the text) [Edit] I'm aware the regex for this is something like href="([^"])*". But I'd like to know how to go about this in Actionscript. Specifically, how can they be pushed into an array in Actionscript?

  • What norms/API for monitoring my servers?

    - by dystroy
    I have a dozen server applications installed on my customers intranets (they can send http requests over the internet but cannot be called from outside). They're written in various technologies, mainly java and Go. I want them to regularly push information about their state towards a central server which is visible on internet. Some of this information is generic (is it ON ?), some is specific (size of a cache in an application for example). The main goal is to be able to make a small web page on which I could instantly check the state of every servers. And maybe later add some kind of notification in case of problem. Obviously I can do this by writing a few dozen lines of code each side (or a little more if I put this data in a database) but in order to ease future evolution, it could be interesting to use some existing norms or libraries. So, what are the current opensource free and light solutions to do this, preferably with no central configuration when I add a server ? I'd prefer a norm over a library.

  • Auto complete from database using CodeIgniter (Active Record)

    I have a form on my website in which one is able to submit a cat.

  • embed multiple youtube videos to chromeless player cue

    - by Quaze
    So in the project ive been working on i use the youtube API to add a video to a chromeless player (got custom buttons, everything works no problems). It loads the youtube id which it gets from the database (Codeigniter, PHP). But what i would like to see is: instead of loading 1 video, id like to add all the videos i get from the database in the cue of that one player. So only one screen, first video retrieved from dbase gets played first, when its done second get loaded preferably also looped. Is there any way i can achieve this? My first guess would be to save the array with youtube id's somewhere and on state change (when the 'video stop'-event gets fired) load the next id from the array. Havent tried this yet because id prefer if the cue gets just gets filled on the init, so it doesnt have to load after a video has been ended. Is This possible?

  • Is Clojure, Scala and other restrained by the JVM vs CLR

    - by jia93
    The Java implementors seem slow to adopt language improvements, for example compare C# with full closures, expression trees, LINQ etc.. to Java, and even the push back of some stuff to Java 8 will still leave it behind the current implementation of C#. However since I dont intend to use either Java or C# that particular language war isnt of interest too much, im more concerned with the JVM vs CLR. Is this lagging-behind also applicable to the JVM? Will Scala, Clojure etc.. will they be able to continue to innovate or score optimal performance in the face of slowly progressing underlying VM such as JVM? Is Clojure/Scala restrained at present by JVM limitations?
