  • Android - overlay small check icon over specific image in gridview or change border

    - by oscar
    I've just asked a question about an hour ago, while waiting for replies, I've thought maybe I can achieve what I want differently. I was thinking of changing the image but it would be better if I could perhaps overlay something over the top of complete levels in the gridview i.e a small tick icon At the moment, when a level has been completed I am storing that with sharedpreferences So I have a gridView layout to display images that represent levels. Let's just say for this example I have 20 levels. When one level is complete is it possible to overlay the tick icon or somehow highlight the level image. Maybe change the border of the image?? Here are the image arrays I use int[] imageIDs = { R.drawable.one, R.drawable.two, R.drawable.three, R.drawable.four, R.drawable.five, R.drawable.six etc....... and then I have my code to set the images in gridView. Obviously there is more code in between. public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView; if (convertView == null) { imageView = new ImageView(context); imageView.setLayoutParams(new GridView.LayoutParams(140, 140)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(5, 5, 5, 5); } else { imageView = (ImageView) convertView; } imageView.setImageResource(imageIDs[position]); return imageView; would it be possible to do any of the above, even the border method would be fine. Thanks for any help

  • Tree data in MySql database table

    - by Robert Koritnik
    I have a table that uses Adjacency list model for hierarchy storage. My most relevant columns in this table are therefore: ItemId // is auto_increment ParentId Level ParentTrail // in the form of "parentId/../parentId/itemId" then I created a before insert tigger, that populates columns Level and ParentTrail. Since the last column also includes current item's ID I had to use a trick in my trigger because auto_increment columns are not available in the before insert trigger. So I get that value from the information_schema.tables table. All works fine, until I try to write an update trigger, that would update my item and its descendants when the item changes its parent (ParentId has changed). But I can't make an update on my table inside the update trigger. All I can do is to change current record's values but not other's. I could use a separate table for hierarchy data, but that would mean that I would also have to create a view that would combine these two tables (1:1 relation) and I would like to avoid this is at all possible. Is there a way to have all these in the same table so that these fields (Level and ParetTrail) set/update themselves automagically using triggers?

  • Leveraging hobby experience to get a job

    - by Bernard
    Like many other's I began programming at an early age. I started when I was 11 and I learned C when I was 14 (now 26). While most of what I did were games just to entertain myself I did everything from low level 2D graphics, and binary I/O, to interfacing with free API's, custom file systems, audio, 3D animations, OpenGL, web sites, etc. I worked on a wide variety of things trying to make various games. Because of this experience I have tested out of every college level C/C++ programming course I have ever been offered. In the classes I took, my classmates would need a week to do what I finished in class with an hour or two of work. I now have my degree now and I have 2 years of experience working full time as a web developer however I would like to get back into C++ and hopefully do simulation programming. Unfortunately I have yet to do C++ as a job, I have only done it for testing out of classes and doing my senior project in college. So most of what I have in C++ is still hobby experience and I don't know how to best convey that so that I don't end up stuck doing something too low level for me. Right now I see a job offer that requires 2 years of C++ experience, but I have at least 9 (I didn't do C++ everyday for the last 14 years). How do I convey my experience? How much is it truly worth? and How do I get it's full value? The best thing that I can think of is a demo and a portfolio, however that only comes into play after an interview has been secured. I used a portfolio to land my current job. All answers and advice are appreciated.

  • Java: Embedding Soundbank file in JAR

    - by Pyroclastic
    If I have a soundbank stored in a JAR, how would I load that soundbank into my application using resource loading...? I'm trying to consolidate as much of a MIDI program into the jar file as I can, and the last thing I have to add is the soundbank file I'm using, as users won't have the soundbanks installed. I'm trying to put it into my jar file, and then load it with getResource() in the Class class, but I'm getting an InvalidMidiDataException on a soundbank that I know is valid. Here's the code, it's in the constructor for my synthesizer object: try { synth = MidiSystem.getSynthesizer(); channels = synth.getChannels(); instrument = MidiSystem.getSoundbank(this.getClass().getResource("img/soundbank-mid.gm")).getInstruments(); currentInstrument = instrument[0]; synth.loadInstrument(currentInstrument); synth.open(); } catch (InvalidMidiDataException ex) { System.out.println("FAIL"); instrument = synth.getAvailableInstruments(); currentInstrument = instrument[0]; synth.loadInstrument(currentInstrument); try { synth.open(); } catch (MidiUnavailableException ex1) { Logger.getLogger(MIDISynth.class.getName()).log(Level.SEVERE, null, ex1); } } catch (IOException ex) { Logger.getLogger(MIDISynth.class.getName()).log(Level.SEVERE, null, ex); } catch (MidiUnavailableException ex) { Logger.getLogger(MIDISynth.class.getName()).log(Level.SEVERE, null, ex); }

  • Learning libraries without books or tutorials

    - by Kawili-wili
    While many ask questions about where to find good books or tutorials, I'd like to take the opposite tack. I consider myself to be an entry-level programmer ready to move up to mid-level. I have written code in c, c++, c#, perl, python, clojure, vb, and java, so I'm not completely clueless. Where I see a problem in moving to the next level is learning to make better use of the literally hundreds upon hundreds of libraries available out there. I seem paralyzed unless there is a specific example in a book or tutorial to hand-hold me, yet I often read in various forums where another programmer attempts to assist with a question. He/she will look through the docs or scan the available classes/methods in their favorite IDE and seem to grok what's going on in a relatively short period of time, even if they had no previous experience with that specific library or function. I yearn to break the umbilical chord of constantly spending hour upon hour searching and reading, searching and reading, searching and reading. Many times there is no book or tutorial, or if there is, the discussion glosses over my specific needs or the examples shown are too far off the path for the usage I had in mind or the information is outdated and makes use of deprecated components or the library itself has fallen out of mainstream, yet is still perfectly usable (but no docs, books, or tutorials to hand-hold). My question is: In the absence of books or tutorials, what is the best way to grok new or unfamiliar libraries? I yearn to slicken the grok path so I can get down to the business of doing what I love most -- coding.

  • Castle windsor security exception

    - by Sunil
    I developed a small WCF service that uses Castle Windsor IoC container and it works fine on my PC. When I deploy it onto a Win 2008 R2 server and host the WCF service in IIS 7 it fails with the following error. I checked the server level web.config and the trust level is set to "Full". What do I need to do to get this to work. As a test I deployed the same service as it is onto a Windows 2003 server with the trust level set to "Full" and it works fine. I am unable to figure out what setting/configuration I am missing on the 2008 server that is making the service fail.

  • event listener says NetStream.Play.Start but I see no video

    - by Curtis
    I'm trying to test out the Adobe Media Server, and I'm following some tutorials in order to stream a video. I have a NetConnection which successfully connects to the application on the server, then I have the code below. It looks like it's supposed to play a video, but it doesn't. It creates the video object as a black square in the top left corner, and the event.info.code says NetStream.Play.Start, but I don't see the video playing. case "NetConnection.Connect.Success": var v:Video = new Video(); v.width=200; v.height=200; v.x=0; v.y=0; v.visible=true; v.opaqueBackground=false; stage.addChild(v); var ns:NetStream = new NetStream(nc); ns.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler); v.attachNetStream(ns); ns.play("mp4:polymorphics.f4v"); I can also try ns.play("rtmp://localhost/vod/mp4:tests/polymorphics.f4v"); but that gives me a Stream Not Found error The lines that begin with "ns" means that they're generated by my NetStream listener, as opposed to my NetConnection listener.

  • How to reference other documents in a couchDB view (joining like functionality)

    - by Surfrdan
    We have a CouchDB representation of an XML database which we use to power a javascript based frontend for manipulating the XML documents. The basic structure is a simple 3 level hierachy. i.e. A - B - C A: Parent doucument (type A) B: any number of child documents of parent type A C: any number of child documents of parent type B We represent these 3 document types in CouchDB with a 'type' attribute: e.g. { "_id":"llgc-id:433", "_rev":"1-3760f3e01d7752a7508b047e0d094301", "type":"A", "label":"Top Level A document", "logicalMap":{ "issues":{ "1":{ "URL":"http://hdl.handle.net/10107/434-0", "FILE":"llgc-id:434" }, "2":{ "URL":"http://hdl.handle.net/10107/467-0", "FILE":"llgc-id:467" etc... } } } } { "_id":"llgc-id:433", "_rev":"1-3760f3e01d7752a7508b047e0d094301", "type":"B", "label":"a B document", } What I want to do is produce a view which returns documents just like the A type but includes the label attribute from the B document within the logicalMap list e.g. { "_id":"llgc-id:433", "_rev":"1-3760f3e01d7752a7508b047e0d094301", "type":"A", "label":"Top Level A document", "logicalMap":{ "issues":{ "1":{ "URL":"http://hdl.handle.net/10107/434-0", "FILE":"llgc-id:434", "LABEL":"a B document" }, "2":{ "URL":"http://hdl.handle.net/10107/467-0", "FILE":"llgc-id:467", "LABEL":"another B document" etc... } } } } I'm struggling to get my head around the best way to perform this. It looks like it should be fairly simple though!

  • Drupal theme preprocess function - primary links and suckerfish menus

    - by slimcady
    I have a preprocess function that works fine when the menu is single level list. However I would like it to work w/ suckerfish menus. I want to add a class to the top level menu item so that I can style it. This is the code I used for the single level menu: function cti_flex_preprocess_page(&$vars, $hook) { // Make a shortcut for the primary links variables $primary_links = $vars['primary_links']; // Loop thru the menu, adding a new class for CSS selectors $i = 1; foreach ($primary_links as $link => $attributes){ // Append the new class to existing classes for each menu item $class = $attributes['attributes']['class'] . " item-$i"; // Add revised classes back to the primary links temp variable $primary_links[$link]['attributes']['class'] = $class; $link['title'] = '<span class="hide">' . check_plain($link['title']) . '</span>'; $i++; } // end the foreach loop // reset the variable to contain the new markup $vars['primary_links'] = $primary_links; } I've been trying to use the menu_tree() function to no avail, for example: function cti_flex_preprocess_page(&$vars, $hook) { // Make a shortcut for the primary links variables $primary_links = $vars['primary_links']; // Loop thru the menu, adding a new class for CSS selectors $i = 1; foreach ($primary_links as $link => $attributes){ // Append the new class to existing classes for each menu item $class = $attributes['attributes']['class'] . " item-$i"; // Add revised classes back to the primary links temp variable $primary_links[$link]['attributes']['class'] = $class; $link['title'] = '<span class="hide">' . check_plain($link['title']) . '</span>'; $i++; } // end the foreach loop // reset the variable to contain the new markup $vars['primary_links_tree'] = menu_tree(variable_get('menu_primary_links_source', '$primary_links')); } Any ideas would be greatly appreciated.

  • How to split up levels? (cocos2d,box2d,iphone) to save CPU and memory?

    - by cocos2dbeginner
    Hi, so I'm going to create large levels. But there's a problem: There's much unseen space (it's a jump'n run like mario bros.) and this will use memory + cpu. so how could I split up my levels? I'm using Box2D+ cocos2d for iphone. Any ideas? Mayby just set the visible property to NO? But it would be still in the memory :(. But what with the box2d bodies? Destroy and recreate them would be to heavy for the FPS, because I have physics built in which should not be recreated. Should I make fix points where i want to split the level up, than if the player is 200 px away it should preload it. and if the player is 200 px away from the last part of the level I unload it. But there would be the problem with the physics, because on the start of the level it has a unique movement and later if i destroy and recreate it it would do the same. but i don't want that. other ideas?

  • How can I restore the "auto" values with for list-style-type in nested unordered lists with CSS?

    - by Michael
    By default, an unstyled set of nested <ul> lists looks like this (in Chrome, Firefox, and IE at least): The top level has a list-style-type of disc, the next level is circle, and subsequent levels are square. If I include a stylesheet that changes the list-style-type to none, is there a simple way to revert back to the "automatic bullet types" later in the document? (e.g., override with a subsequent CSS definition or JavaScript style change) Basically, I'm looking for something like list-style-type: auto; (which is apparently not valid and has no effect): <style type="text/css"> ul { list-style-type: none; } ul { list-style-type: auto; } /* Does not work */ </style> Setting the list-style-type back to disc changes every bullet in the list and I no longer see different bullets at different levels, so that doesn't work either. Is the only way to accomplish this by explicitly defining styles for every level? e.g.: <style type="text/css"> ul { list-style-type: disc; } ul ul { list-style-type: circle; } ul ul ul { list-style-type: square; } </style>

  • SSRS How to access the current value within a list control?

    - by Dale Burrell
    In SQL Server Reporting Services I have a report which has a list control which groups on currency. Within the list control I display the detailed rows of all records filtered to those with a value = £500. i.e. the top earners. However for each row I need to calculate the percentage of its amount over the total of the entire dataset. Because I am filtering it I can't use Sum(Fields!Amount.Value) as that only sums the data after filtering, so I am trying a conditional sum over the entire dataset, but am struggling with the correct condition e.g =100.00*Fields!Amount.Value/Sum((IIf(Fields!Currency.Value = "£", Fields!Amount.Value, CDec(0))),"DataSet") So where the hardcoded currency symbol is I need to access the current value of currency for the list control, but because my sum is scoped at dataset level any field access is dataset level. Ideally I'd like something like the following, otherwise any other ideas on how to solve this problem. =100.00*Fields!Amount.Value/Sum((IIf(Fields!Currency.Value = myListControl.Value, Fields!Amount.Value, CDec(0))),"DataSet") In fact, thinking about it, it would work if I just could access the row level data at that point, but how to do that when its at dataset scope within the sum statement? Hope that makes sense, any help appreciated.

  • How to collect and inject all beans of a given type in Spring XML configuration

    - by GrzegorzOledzki
    One of the strongest accents of the Spring framework is the Dependency Injection concept. I understand one of the advices behind that is to separate general high-level mechanism from low-level details (as announced by Dependency Inversion Principle). Technically, that boils down to having a bean implementation to know as little as possible about a bean being injected as a dependency, e.g. public class PrintOutBean { private LogicBean logicBean; public void action() { System.out.println(logicBean.humanReadableDetails()); } //... } <bean class="PrintOutBean"> <property name="loginBean" ref="ShoppingCartBean"/> </bean> But what if I wanted to a have a high-level mechanism operating on multiple dependent beans? public class MenuManagementBean { private Collection<Option> options; public void printOut() { for (Option option:options) { // do something for option } //... } } I know one solution would be to use @Autowired annotation in the singleton bean, that is... @Autowired private Collection<Option> options; But doesn't it violate the separation principle? Why do I have to specify what dependents to take in the very same place I use them (i.e. MenuManagementBean class in my example)? Is there a way to inject collections of beans in the XML configuration like this (without any annotation in the MMB class)? <bean class="MenuManagementBean"> <property name="options"> <xxx:autowire by-type="MyOptionImpl"/> </property> </bean>

  • How do i set the Transaction Isolation in EJB?

    - by Nitesh Panchal
    Hello, I am not able to find a way to set TransactionIsolation in ejb. Can anybody tell me how do i set it? I am using persistence. I have looked the following classes : EntityManager , EntityManagerFactory, UserTransaction. None of them seems to have any method like setTransactionIsolation or such. Do we need to change persistence.xml? I just read a book named Mastering EJB 3.0 4th edition. They gave a full 10 page theory about Isolation level that this problems occur and that occurs and such things but at the end they gave this paragraph :- "As we now know, the EJB standard does not deal with isolation levels directly, and rightly so. EJB is a component specification. It defines the behavior and contracts of a business component with clients and middleware infrastructure (containers) such that the component can be rendered as various middleware services properly. EJBs therefore are transactional components that interact with resource managers, such as the JDBC resource manager or JMS resource manager, via JTS, as part of a transaction. They are not, hence, resource components in themselves. Since isolation levels are very specific to the behavior and capabilities of the underlying resources, they should therefore be specified at the resource API levels. " What exactly does it mean? What is meant by resource level APIs? Please help me. If persistence has no way to set Isolation Level then why do they give such huge theory in an EJB book and make it heavy in weight unnecessarily :(

  • Need some clarification on the ANSI/SPARC 3-tier database architecture.

    - by Moonshield
    Hi there, I'm currently revising for a databases exam and looking over some past papers, but there's one question that I'm slightly unsure about and was wondering if someone could offer some assistance. "Describe EACH of the THREE levels of the ANSI SPARC 3 level architecture. Your answer should include the purpose of EACH of the schemas, the level of abstraction they provide and the software tools that would be used to access and support them." As I understand it (although please correct me if I'm wrong): the internal schema specifies the physical storage of the data; the conceptual schema specifies the structure of the database and the domains; and the external schemas are how the database is viewed by "users" (applications, etc.). As for the abstraction, I understand that the conceptual layer means that the physical data storage can be altered without the end user being affected, likewise the The bit that I'm not sure about is what tools are used to access and support each layer. Would the internal schema be handled by the DBMS, the conceptual schema handled by some sort of DDL interpreter and the external schema handled by a DML interpreter (or have I misunderstood what each level does)? Any assistance would be greatly appreciated. Thanks, Moonshield

  • Does anyone still believe in the Capability Maturity Model for Software?

    - by Ed Guiness
    Ten years ago when I first encountered the CMM for software I was, I suppose like many, struck by how accurately it seemed to describe the chaotic "level one" state of software development in many businesses, particularly with its reference to reliance on heroes. It also seemed to provide realistic guidance for an organisation to progress up the levels improving their processes. But while it seemed to provide a good model and realistic guidance for improvement, I never really witnessed an adherence to CMM having a significant positive impact on any organisation I have worked for, or with. I know of one large software consultancy that claims CMM level 5 - the highest level - when I can see first hand that their processes are as chaotic, and the quality of their software products as varied, as other, non-CMM businesses. So I'm wondering, has anyone seen a real, tangible benefit from adherence to process improvement according to CMM? And if you have seen improvement, do you think that the improvement was specifically attributable to CMM, or would an alternative approach (such as six-sigma) have been equally or more beneficial? Does anyone still believe? As an aside, for those who haven't yet seen it, check out this funny-because-its-true parody

  • Use string to store statement (or part of a statement), and then add it to the code

    - by Dean
    I use multidimensional arrays to store product attributes (well Virtuemart does, to be precise). When I tried to echo the sub-arrays value, if the sub-array did not exist PHP threw: Fatal error: Cannot use string offset as an array To get around this, I attempted to create a function to check on every array level if it is an actual array, and if it is empty (when trying on the whole thing at once such as: is_array($array['level1']['level2']['level3']), I got the same error if level1 or level2 are not actual arrays). This is the function ($array contains the array to check, $array_levels is an array containing the names of the sub-arrays, in the order they should apper): function check_md_array($array,$array_levels){ if(is_array($array)){ $dimension = null; //This will store the dimensions string foreach($array_levels as $level){ $dimension .= "['" . $level . "']"; //Add the current dimension to the dimensions string if(!is_array($array/* THE CONTENT OF $dimension SHOULD BE INSERTED HERE*/)){ return false; } } return true; } } How can I take the string contained in $dimensions, and insert it into the code, to be part of the statement?

  • Creating Modules for VB Program (Similar to firefox add on)

    - by Assimilater
    Hi all. I have a contact manager program that I'd like to design for multiple network marketing companies. My desired structure would include a core program which covers basic contact management functions. After that one could purchase a module for their specific network marketing company. This module would contain a variety of controls that the original program would need to be able to manipulate. Here is an example of what it would have to have: A group box containing buttons that link to a genealogy view, and the option to import one's donwnline from the back office provided by a company. A panel which is displayed on the contact page allowing the user to input business information or which will be filled by importing a downline from the back office: ie business ID, qualification level, sponsor information etc. a panel displayed when one searches for contacts on the contact list page which allows the user to sort based on information such as when they joined, what their business id is and so forth. a panel which is displayed in a personal business overview page which presents to an individual how many people in their downline are at each qualification level and develop a mailing list for individuals of a certain qualification level. I have the code developed to perform all these functions, I just wanted to give you an example of what needed to be done. I'm thinking that what I'm trying to create is a library that one can download and the program will recognize, but I'm not really sure where to go. What I'm really trying to do is figure out what kind of file I can make that will contain all this code and the GUI information that the program will recognize. Any ideas? With thanks, John

  • Forwarding HTTP Request with Direct Server Return

    - by Daniel Crabtree
    I have servers spread across several data centers, each storing different files. I want users to be able to access the files on all servers through a single domain and have the individual servers return the files directly to the users. The following shows a simple example: 1) The user's browser requests http://www.example.com/files/file1.zip 2) Request goes to server A, based on the DNS A record for example.com. 3) Server A analyzes the request and works out that /files/file1.zip is stored on server B. 4) Server A forwards the request to server B. 5) Server B returns file1.zip directly to the user without going through server A. Note: steps 4 and 5 must be transparent to the user and cannot involve sending a redirect to the user as that would violate the requirement of a single domain. From my research, what I want to achieve is called "Direct Server Return" and it is a common setup for load balancing. It is also sometimes called a half reverse proxy. For step 4, it sounds like I need to do MAC Address Translation and then pass the request back onto the network and for servers outside the network of server A tunneling will be required. For step 5, I simply need to configure server B, as per the real servers in a load balancing setup. Namely, server B should have server A's IP address on the loopback interface and it should not answer any ARP requests for that IP address. My problem is how to actually achieve step 4? I have found plenty of hardware and software that can do this for simple load balancing at layer 4, but these solutions fall short and cannot handle the kind of custom routing I require. It seems like I will need to roll my own solution. Ideally, I would like to do the routing / forwarding at the web server level, i.e. in PHP or C# / ASP.net. However, I am open to doing it at a lower level such as Apache or IIS, or at an even lower level, i.e. a custom proxy service in front of everything.

  • Is there any way to configure what reCAPTCHA is actually displaying?

    - by trejder
    Is there any way to control, what kind of image is displayed to user in reCAPTCHA or what kind of puzzle he/she is required to solve? I noticed at least two significant changes to what reCAPTCHA is serving (and I must admit, that I don't much like these changes): For years reCAPTCHA was serving two words from scanned books and user was required to solve one of them. They were clearly readable (even those "second" ones, that could be ommitted) and with nearly no problem in solving them by a human. For past few month, I noticed a significant change at all of my sites, that are using reCAPTCHA. They started to show combination of computer-generated long numbers string and something, that looks for me as street/house number photographed in Google StreetView. They're even easier to solve, but what is most important -- it started to happen more and more often that user is obligated to solve both of them. Now, I have noticed another change/regression. Now some of my sites remain at so called "level 2" (like above) and some of them started to serve two words again ("level 1"?). And again, there are more and more situations, where solving both words is required. But, what is most important, on this "level" words are nearly impossible to solve (on my old mobile devices with 3.5'' display I need 5-6 attempts to pass on!). They're cluttered, written in some strange font, mostly in italics with a lot of black and white stains or drops on letters etc. Plus: reCAPTCHA stopped to be equal -- some of my pages are still serving "level2" while some of them are "killing" end users with a need to solve "level3". Is there anyway, I can control this -- force it to use only "level2" and on all my pages? (of course, I'm using exactly the same piece of code to serve reCAPTCHA on all my pages) Note, that I'm not asking for something like in this question. I don't want to change what reCAPTCHA shows (to disable words in favor of only numbers for example). I only want to control, which "version" of puzzles (among described above) reCAPTCHA shows and I want to make it equal on all my sites.

  • Optimized 2D Tile Scrolling in OpenGL

    - by silicus
    Hello, I'm developing a 2D sidescrolling game and I need to optimize my tiling code to get a better frame rate. As of right now I'm using a texture atlas and 16x16 tiles for 480x320 screen resolution. The level scrolls in both directions, and is significantly larger than 1 screen (thousands of pixels). I use glTranslate for the actual scrolling. So far I've tried: Drawing only the on-screen tiles using glTriangles, 2 per square tile (too much overhead) Drawing the entire map as a Display List (great on a small level, way to slow on a large one) Partitioning the map into Display Lists half the size of the screen, then culling display lists (still slows down for 2-directional scrolling, overdraw is not efficient) Any advice is appreciated, but in particular I'm wondering: I've seen Vertex Arrays/VBOs suggested for this because they're dynamic. What's the best way to take advantage of this? If I simply keep 1 screen of vertices plus a bit of overdraw, I'd have to recopy the array every few frames to account for the change in relative coordinates (shift everything over and add the new rows/columns). If I use more overdraw this doesn't seem like a big win; it's like the half-screen display list idea. Does glScissor give any gain if used on a bunch of small tiles like this, be it a display list or a vertex array/VBO Would it be better just to build the level out of large textures and then use glScissor? Would losing the memory saving of tiling be an issue for mobile development if I do this (just curious, I'm currently on a PC)? This approach was mentioned here Thanks :)

  • Concurrent usage of table causing issues

    - by Sven
    Hello In our current project we are interfacing with a third party data provider. They need to insert data in a table of ours. This inserting can be frequent every 1 min, every 5min, every 30, depends on the amount of new data they need to provide. The use the isolation level read committed. On our end we have an application, windows service, that calls a webservice every 2 minutes to see if there is new data in this table. Our isolation level is repeatable read. We retrieve the records and update a column on these rows. Now the problem is that sometimes this third party provider needs to insert a lot of data, let's say 5000 records. They do this per transaction (5rows per transaction), but they don't close the connection. They do one transaction and then the next untill all records are inserted. This caused issues for our process, we receive a timeout. If this goes on for a long time the database get's completely unstable. For instance, they maybe stopped, but the table somehow still stays unavailable. When I try to do a select on the table, I get several records but at a certain moment I don't get any response anymore. It just says retrieving data but nothing comes anymore until I get a timeout exception. Only solution is to restart the database and then I see the other records. How can we solve this. What is the ideal isolation level setting in this scenario?
