  • Database suggestion

    - by superartsy
    I am working on an enterprise level product that is designed around SQL Express Database ( views,concurrent users,stored procedures,case,IF).Though we dont use any SQL Server advanced features, if the database size of 4Gb in express ends up being a limitation customers can move to advanced versions of SQL Server. However my problem is, SQL Express deployment is not easy and the installer size is huge. This is a major drawback for someone looking to try our product.You dont want end users to not buy a product becos the download is huge. Does anyone have any recommendations of a database that has a smaller footprint but all the features of Express and which can be migrated to express?

  • HTML, jQuery Suggestion for a List

    - by AnApprentice
    Hello, I'm creating an app that will have a list of messages, each message can be either read or unread. Think GMAIL (though I'm not trying to rebuild that)... My question is when I output all these messages, I need to list if the message is read or unread, I also need to provide the ability to change the message status, from read to unread. That being said, how do you suggest I stored this? A checkbox, a hidden input value? Any thoughts? Thanks

  • Pop up password protect

    - by steve
    Please not that I fully understand this is a dumb ass idea, but its not my idea. We need to deter people visiting a certain page on our site. It's written in ASP and I don'tknow ASP! Can anyone tell me how I can have a pop up box load when the URL is visited where by people have to enter a username / password. The user name / password should be stored in the javascript. (Yes I know) The only real requirement is that this happen anytime the page is loaded and it stays on that page. So the page is test.asp - javascript pops up they enter credentials and if right remain on test.asp Thanks

  • Database for Large number of 1kB data chunks (MySQL?)

    - by The Unknown
    I have a very large dataset, each item in the dataset being roughly 1kB in size. The data needs to be queried rapidly by many applications distributed over a network. The dataset has more than a million items (so 500 million+ 1kB data chunks). What would be the best method to storing this dataset (need to allow adding more items, and reading them rapidly, but never modifying already added data)? Would using a MySQL DB using the binary blob format be appropriate? Or should each of these be stored as files on a file system? edit: the number is 1 million items now, but needs to be able to scale to well over 500 million items easily.

  • How do I create "undo" in c++?

    - by b3y4z1d
    I've got a couple of codes to do some things but I need to create a function that undoes the previous task/addition/change.How do I do this in Borland C++? (the program stores strings of text in a text file using "list",it is stored and then erased unless I use the save-function I've created) right,so I don't know if I've forgotten to mention anything of importance for you to be able to help me better,but if there's something you're wondering about the functions just ask. I meant creating an undo function in a simple consol application by the way.

  • How can I see included JavaScript sources?

    - by Toddintr
    I am trying to script a web page using GreaseMonkey. (I am using Firebug for help in development.) The page has a small amount of JavaScript code, but that code pulls in other JS files from the site. Are the entire collection of JS files stored somewhere on the client side (i.e. on the filesystem somewhere) so that I can view them? Or better yet, is there a way I can view them in Firebug? I am a little overwhelmed by Firebug but will be able to follow instructions. Many thanks. (My first ever question on SO!) -Todd

  • How to read binary column in database into image on asp.net page?

    - by marko
    I want to read from database where I've stored a image in binary field and display a image. while (reader.Read()) { byte[] imgarr = (byte[])reader["file"]; Stream s = new MemoryStream(imgarr); System.Drawing.Image image = System.Drawing.Image.FromStream(s); Graphics g = Graphics.FromImage(image); g.DrawImage(image, new Point(400, 10)); image.Save(Response.OutputStream, ImageFormat.Jpeg); g.Dispose(); image.Dispose(); } con.Close(); This piece of code doesn't work: System.Drawing.Image image = System.Drawing.Image.FromStream(s); What am I doing wrong?

  • What is wrong with my @synchronized block?

    - by hyn
    I have 2 threads in my application, a game update thread and render/IO/main thread. My update thread updates the game state, and the render thread renders the scene based on the updated values of the game state models and a few other variables stored inside an object (gameEngine). The render thread gets executed while the game thread is still updating, which is a problem, so it appeared to me the solution is to use @synchronized like this: @synchronized(gameEngine) { [gameEngine update]; nextUpdate = now + GAME_UPDATE_INTERVAL; gameEngine.lastGameUpdateInterval = now - lastUpdate; gameEngine.lastGameUpdateTime = now; lastUpdate = now; } But the render thread still accesses the gameEngine object between -update and the last 3 lines of the block. Why is this?

  • Statically Init a derived class

    - by AC
    With c++, Is there a way to get a derived class to inherit its own static initializer? I am trying to do something like the following: class Base { public: class StaticInit { public: virtual StaticInit() =0; }; }; class Derived: public Base { public: virtual StaticInit::StaticInit() { //do something with the derived class } static StaticInit init; } static Derived::StaticInit init; it would also be nice if I didn't have to define the init var in each derived class. I am currently redefining the StaticInit internal class in each derived class but it seems redundant. Each derived class is a singleton, and I need the instance to be stored in a lookup table at program startup.

  • iPhone CoreData Migration and modifying data

    - by ScottL
    I have an app that has both static data and user entered data in the CoreData store. I understand how to do a lightweight migration to a new database version, but how to I add or modify the static data without affecting the users data? If I have 50 static data entries to add and a couple to modify (ie. spelling mistakes) should they be stored in a different sqlite db and copied over? Also, is it possible to look at the version of the data store so that this copy only happens the first time the app is started up after upgrading? Sorry for the general noob type question, but this is the first time I have ever had to deal with this sort of issue. Thanks, Scott

  • transform file/directory structure into 'tree' in javascript

    - by dave
    I have an array of objects that looks like this: [{ name: 'test', size: 0, type: 'directory', path: '/storage/test' }, { name: 'asdf', size: 170, type: 'directory', path: '/storage/test/asdf' }, { name: '2.txt', size: 0, type: 'file', path: '/storage/test/asdf/2.txt' }] There could be any number of arbitrary path's, this is the result of iterating through files and folders within a directory. What I'm trying to do is determine the 'root' node of these. Ultimately, this will be stored in mongodb and use materialized path to determine it's relationships. In this example, /storage/test is a root with no parent. /storage/test/asdf has the parent of /storage/test which is the parent to /storage/test/asdf/2.txt. My question is, how would you go about iterating through this array, to determine the parent's and associated children? Any help in the right direction would be great! Thank you

  • Set Hibernate session's flush mode in Spring

    - by glaz666
    I am writing integration tests and in one test method I'd like to write some data to DB and then read it. @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"classpath:applicationContext.xml"}) @TransactionConfiguration() @Transactional public class SimpleIntegrationTest { @Resource private DummyDAO dummyDAO; /** * Tries to store {@link com.example.server.entity.DummyEntity}. */ @Test public void testPersistTestEntity() { int countBefore = dummyDAO.findAll().size(); DummyEntity dummyEntity = new DummyEntity(); dummyDAO.makePersistent(dummyEntity); //HERE SHOULD COME SESSION.FLUSH() int countAfter = dummyDAO.findAll().size(); assertEquals(countBefore + 1, countAfter); } } As you can see between storing and reading data, the session should be flushed because the default FushMode is AUTO thus no data can be actually stored in DB. Question: Can I some how set FlushMode to ALWAYS in session factory or somewhere else to avoid repeating session.flush() call? All DB calls in DAO goes with HibernateTemplate instance. Thanks in advance.

  • how to get audio frequency data from a wave file?

    - by potlee
    I want to build a speech recognition engine in ruby. I know i'll never get there, doing it just for fun. I need to get data for the frequencies of the sound stored in a wav file to compare with data i already have of different sounds that i want to recognize. I will write the code in ruby but i dont think there are any libraries for this written in ruby, they would be too slow if there were any anyway. The good thing about ruby is I'll be able to use libraries for .net via IronRuby or Java via Jruby. How can i get the frequency data?

  • How to allow certain HTML tags in a form field in Symfony 1.2

    - by camomileCase
    I'm playing around with Symfony and have encountered a road block. I created a model "CmsPage" which has a field called "content" which is stored as a clob (this is specific to doctrine I believe). When I created the app I set "--escaping-strategy=on" so if I enter any html when editing a CmsPage that gets encoded with html entities or something along those lines. I would like to allow html in this field and a quick googling hasn't helped much. Maybe I'm searching for the wrong terms. Anywho I would like to disable character escaping for this field and possibly only allow a small selection of html tags. What is the correct way to do this in Symfony?

  • C++ object in memory

    - by Neo_b
    Hello. Is there a standard in storing a C++ objects in memory? I wish to set a char* pointer to a certain address in memory, so that I can read certain objects' variables directly from the memory byte by byte. When I am using Dev C++, the variables are stored one by one right in the memory address of an object in the order that they were defined. Now, can it be different while using a different compiler (like the variables being in a different order, or somewhere else)? Thank you in advance. :-)

  • SQL database self interaction entity

    - by Ricardo Costa
    I've been working on a database, wich is referent to an Aeroport management. I'm having a problem that it's freaking me out.. What i'm trying to do is, assuming that a client wants to know the distance between 2 locations, in miles or kms. As an example, if the user wants to know the distance between London and Amsterdam, should that distance be calculated by a formule or should it be already stored on the database? (1,N) ____________ ____________|__ | | | | | City/Airport |<---------| |______________| How can i show to user the distance between his 2 choices? RicardoCosta

  • Vim: How to handle newlines when storing multiple commands in registers?

    - by UncleZeiv
    I have a file where I store snippets of vim commands. When I need a snippet, I yank it and then execute it with @". The snippets are stored as a script, one line per command, like this: :s/foo/bar/g :echo "hello" :s/1/2/g Edit: I removed normal mode commands from the example, as they were not part of the problem. Now this procedure doesn't work anymore: when executing the snippet, it just stops at the first line as if waiting for a newline. Is there an option somewhere affecting how @ is executed? I'm pretty sure it was working some time ago... Substituting the newline with a ^M character works but makes the file more difficult to handle. Additional information: Here's another symptom: when I yank a snippet, if I execute it with @" it stops at the first line as I just explained. But if I execute it with :@ it works. But the help file doesn't seem to imply any difference in how the two commands treat the register's content...

  • Yes another ON DUPLICATE KEY UPDATE query

    - by Andy Gee
    I've been reading all the questions on here but I still don't get it I have two identical tables of considerable size. I would like to update table packages_sorted with data from packages_sorted_temp without destroying the existing data on packages_sorted Table packages_sorted_temp contains data on only 2 columns db_id and quality_rank Table packages_sorted contains data on all 35 columns but quality_rank is 0 The primary key on each table is db_id and this is what I want to trigger the ON DUPLICATE KEY UPDATE with. In essence how do I merge these two tables by and change packages_sorted.quality_rank of 0 to the quality_rank stored in packages_sorted_temp under the same primary key Here's what's not working INSERT INTO `packages_sorted` ( `db_id` , `quality_rank` ) SELECT `db_id` , `quality_rank` FROM `packages_sorted_temp` ON DUPLICATE KEY UPDATE `packages_sorted`.`db_id` = `packages_sorted`.`db_id`

  • 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?

  • PHP Count the lenght of each value in a array/string (tags)

    - by 2by
    Users writing an article have the option to write some tags, tags are written like this: tag1, tag2, tag3 So tags are stored like: $tags = "tag1, tag2, tag3"; I want to make sure, every tag has a minimum of 3 characters, so i need to validate the tags. I have tried this: $tagsstring = explode(",", $tags); $tagslength = array_map('strlen', $tagsstring); if (min($tagslength) < 3) { echo "Error... Each tag has to be at least 3 characters."; } It seems to work, sometimes... But of you write: tag1, df It wont give an error. Any suggestions?

  • asp.net mvc model - my own database

    - by progtick
    The tutorials I have come across usually let you create a dababase from scratch creating a .mdf file or something and so on. However, what if I already have a SQL Server Express set up with the needed database? How do I tell my model to use that database? Right now, all my model contains is basically some classes that execute stored procedure on my own database and return manupulated data. Should I leave it as it is? What are the benefits of going through the full-fledged model approach that tutorials demonstrate?

  • Rails: Best practice to store user settings?

    - by ole_berlin
    Hi, I'm wondering what the best way is to store user settings? For a web 2.0 app I want users to be able to select certain settings. At the moment is it only when to receive email notifications. The easiest way would be to just create a Model "Settings" and have a column for every setting and then have a 1-1 relationship with users. But is there a pattern to solve this better? Is it maybe better to store the info in the user table itself? Or should I use a table with "settings_name" and "settings_value" to be completely open about the type of settings stored there (without having to run any migrations when adding options)? What is your opinion? Thanks

  • Form Arrays support across browsers

    - by Stomped
    I'm not even sure if form arrays is the proper term, but it looks a bit like this: <input name='element[]' type='text' /> <input name='element[]' type='text' /> Which is then retrieved in PHP as an array stored in $_POST['element'] -- in this case with 2 values. I've tested it in the browsers I have available to me, but I've never seen this before and I'm wondering is this supported pretty much in all browsers? Or is this something very old that I've just not run into? Thanks!
