  • Linq sql Attach, Update Check set to Never, but still Concurrency conflicts

    - by remdao
    In the dbml designer I've set Update Check to Never on all properties. But i still get an exception when doing Attach: "An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. This is not supported." This approach seems to have worked for others on here, but there must be something I've missed. using(TheDataContext dc = new TheDataContext()) { test = dc.Members.FirstOrDefault(m => m.fltId == 1); } test.Name = "test2"; using(TheDataContext dc = new TheDataContext()) { dc.Members.Attach(test, true); dc.SubmitChanges(); }

  • ActionScript 3 class over several files - how?

    - by Poni
    So, how do we write a class over several files in action script 3? In C# there's the "partial" keyword. In C++ it's natural (you just "#include ..." all files). In Flex 3, in a component, you add this tag: <mx:Script source="myfile.as"/>. How do I split the following class into several files; package package_path { public class cSplitMeClass { public function cSplitMeClass() { } public function doX():void { // .... } public function doY():void { // .... } } } For example I want to have the doX() and doY() functions implemented in another ".as" file. Can I do this? And please, don't tell me something like "a good practice is to have them in one file" :)

  • How do I dynamically tell a .NET MVC application which datasource to point to?

    - by Bialecki
    I'm beginning a port of an existing ColdFusion application to .NET MVC and one of the first issues I'm running into is that in ColdFusion we use the fact that you can define multiple datasources and access them in a dynamic way so that a particular user can be pointed at a particular database. To give an example, I might have two databases, Foo and Bar which each have a table called Locations which store locations particular to that database. The databases are guaranteed to have the same tables, so that's not a concern. In ColdFusion, you can easily dynamically point a user towards a particular datasource because it's just a string which is configured via the ColdFusion administrator (or you could programatically modify an XML file). So the question is how to do this in .NET? And specifically, I think I'd really like to use the Entity framework to leverage the ORM support it'll offer to perform operations on the data in the database, but I'm not sure how to do that (hopefully it's possible). Any thoughts?

  • How do I execute file installed by merge module?

    - by Juozas Kontvainis
    I am using WIX and have successfully used a custom action to execute installed file at the end of installer like this: <CustomAction Id="LaunchAfterInstall" FileKey="foobar.exe" ExeCommand="parameters" Execute="immediate" Impersonate="yes" Return="asyncNoWait" /> <Property Id="WIXUI_INSTALLDIR" Value="INSTALLLOCATION"/> <UIRef Id="WixUI_InstallDir" /> <Property Id="WIXUI_EXITDIALOGOPTIONALCHECKBOXTEXT" Value="Launch Foobar." /> <UI> <Publish Dialog="ExitDialog" Control="Finish" Order="1" Event="DoAction" Value="LaunchAfterInstall">WIXUI_EXITDIALOGOPTIONALCHECKBOX</Publish> </UI> This works well when foobar.exe is in a component in the same wxs file. However what I really want is to execute a file that is installed by a merge module. How do I do this? I can make changes in the merge module, if this helps things.

  • Out of Memory When Loading Java Entities

    - by Hugh Buchanan
    I have a terrible problem that hopefully has a very simple answer. I am running out of memory when I perform a basic If I have code like this: MyEntity myEntity; for (Object id: someIdList) { myEntity = find(id); // do something basic with myEntity } And the find() method is a standard EntityManager related method: public MyEntity find(Object id) { return em.find(mycorp.ejb.entity.MyEntity.class, id); } This code worked a couple of weeks ago, and works fine if there are fewer items in the database. The resulting error I am facing is: java.lang.OutOfMemoryError: GC overhead limit exceeded The exception is coming from oracle toplink calling some oracle jdbc methods. The loop exists because an EJBQL such as "select object(o) from MyEntity as o" will overload the application server when there are lots of records.

  • JBoss Seam: components injected into POJOs, but not Session Beans

    - by purecharger
    I have a Seam component that handles login, with the name "authenticator": @Name("authenticator") public class AuthenticatorAction implements Authenticator { @PersistenceContext private EntityManager em; @In(required=false) @Out(required=false, scope = SESSION) private User user; public boolean authenticate(){ ... } } This works just fine, Seam injects the EntityManager instance. However, as soon as I add the @Stateless annotation, none of the injection happens! In this case, the EntityManager instance is null upon entry to the authenticate() method. Another interesting note is that with a separate stateful session bean I have, the Logger instance in that class is only injected if I make it static. If i have it non-static, it is not injected. Thats fine for the logger, but for stateless session beans like that, I obviously can't have static member variables for these components. I'm confused because this authenticator is exactly how it is in the Seam booking example: a stateless session bean with a private member variable being injected. Any ideas?

  • AS3: How to access pixel data efficiently?

    - by JonoRR
    I'm working a game. The game requires entities to analyse an image and head towards pixels with specific properties (high red channel, etc.) I've looked into Pixel Bender, but this only seems useful for writing new colors to the image. At the moment, even at a low resolution (200x200) just one entity scanning the image slows to 1-2 Frames/second. I'm embedding the image and instance it as a Bitmap as a child of the stage. The 1-2 FPS situation is using BitmapData.getPixel() (on each pixel) with a distance calculation beforehand. I'm wondering if there's any way I can do this more efficiently... My first thought was some sort of spatial partioning coupled with splitting the image up into many smaller pieces. I also feel like Pixel Bender should be able to help somehow, however I've had little experience with it. Cheers for any help. Jonathan

  • not readable PDF files

    - by Michal_R
    Hello, I am writing Master's thesis - NLP system. I have one component - extractor. It is extracting a plain text from PDF files. There are a few PDF files that can not be extracted correctly. Extractor (PDFBox library) returns a string like this: "¦xDn¦if|d+gDF"Ti&cD+lh d FÁhis~n +xd f«"d¦ffih »h" or "10a61a91a22a25a3a27a17a23a20a8a13a14a61a25a17" I was checking each file that makes this extraction's problem and all these files' text also can not be copy-pasted from PDF Reader (Adobe Reader and FoxIt reader). Viewing them in this readers is enabled, but after selecting its content and copying to the clipboard I get the same wrong text (as described above - strings of not semanticaly correct chars or strings of digits and letters) Could anybody help me??? THX :)

  • .Net friendly, local, key-value pair, replicatable datastore

    - by Brad Mathews
    I am looking for a key/value type datastore with very specific requirements. Anyone know anything that will work? Needs to be a component of some sort. No additional installation needed. The datastore needs to be on the local hard drive. I am using VB.Net for a desktop app running Windows XP through 7 so it needs to callable by that environment. It needs to replicatable. If I have four copies of my app running on the network, each local copy of the datastore needs to replicate with the others. As close to real time as possible. The first three are easy, I can do that with ADO.Net out of the box. The last one, replication, is the one I do not have answer to. Does such an animal exist? Thanks, Brad

  • Getting consecutive version numbers from Hibernate's @Version usage once per transaction

    - by Cheradenine
    We use Hibernate with the following version definition for optimistic locking et. al: <version name="version" access="field" column="VERSION" type="long" unsaved-value="negative"/> This is fine and dandy; however, there is one small problem, which is that the first version for some entities is '0', and for others, it is '1'. Why this is happening, is that for some object graphs, an entity will be subject to both onSave and flushDirty - this is reasonable, such as if two object are circular dependencies. However, the version number gets incremented on both occasions, leading to the above '0' / '1' discrepancy. I'd really like the version number only to ever increment once per transaction. However, I can't see a simple way to do this in the hibernate versioning implementation, without hacking about with an Interceptor (which was how I generated a column value for version before, but I wanted hibernate to do it itself)..

  • Persist url parameter throughout grails app

    - by avelis
    Essentially I am looking to have a url query parameter persist throughout the life of the grails application (POST or GET). ex. http://localhost:8080/demo/controller/action/?myParam=foobar I have tried a couple routes. Dynamic method overriding redirect and customizing application tags for createLink. However, since I also use grails webflows it doesn't quite get every single URL. I also tried using a groovy servlet (groovlet) to capture every URL and append the query parameter. The last attempt hasn't been very successful. Am I missing an obvious component to grails? Am I on the right track? Is there another avenue I haven't explored yet? Thanks in advance

  • Exception design: Custom exceptions reading data from file?

    - by User
    I have a method that reads data from a comma separated text file and constructs a list of entity objects, let's say customers. So it reads for example, Name Age Weight Then I take these data objects and pass them to a business layer that saves them to a database. Now the data in this file might be invalid, so I'm trying to figure out the best error handling design. For example, the text file might have character data in the Age field. Now my question is, should I throw an exception such as InvalidAgeException from the method reading the file data? And suppose there is length restriction on the Name field, so if the length is greater than max characters do I throw a NameTooLongException or just an InvalidNameException, or do I just accept it and wait until the business layer gets a hold of it and throw exceptions from there? (If you can point me to a good resource that would be good too)

  • Spring constructor injection of SLF4J logger - how to get injection target class?

    - by disown
    I'm trying to use Spring to inject a SLF4J logger into a class like so: @Component public class Example { private final Logger logger; @Autowired public Example(final Logger logger) { this.logger = logger; } } I've found the FactoryBean class, which I've implemented. But the problem is that I cannot get any information about the injection target: public class LoggingFactoryBean implements FactoryBean<Logger> { @Override public Class<?> getObjectType() { return Logger.class; } @Override public boolean isSingleton() { return false; } @Override public Logger getObject() throws Exception { return LoggerFactory.getLogger(/* how do I get a hold of the target class (Example.class) here? */); } } Is FactoryBean even the right way to go? When using picocontainers factory injection, you get the Type of the target passed in. In guice it is a bit trickier. But how do you accomplish this in Spring?

  • Working with NSCalendar -- getting the next first tuesday of a month

    - by Bjorn S.
    Hi all, This is a bit odd, but is it possible to use an NSCalendar (or any component, for that matter) to figure out what the date of the next "first tuesday of the month" would be? For example, today is Thursday March 25, 2010. The next "first tuesday of the month" would be on April 6. Likewise, if I were looking for the next "first tuesday of the month" on April 1, it would still be on April 6. How would you do this? Thanks very much!!!!!

  • How to show scrollbars in TScrollBox after it has been made visible again?

    - by aleluja
    Hi, I've ran into one small problem. I am dynamicaly generating some controls and place them on a TScrollbox component. But i noticed that if scrollbox is visible, user can clearly see each of the controls being created and placed. So it looksl ike lots of work is being done and it is slow. I hid the scrollbox and generated all the controls on it, which took much less time and no flickering and alike. But here's the problem. When i unhide the scrollbox, its' scrollbar doesn't appear untill i actually resize the form. (The alignment of scrollbox is alClient) Any ideas on how to fix this? Tried repainting, but it didn't work. Refresh didn't work either. Thank you

  • JPA query for getting the whole tree

  • insertNewObjectForEntityForName: inManagedObjectContext: returning NSNumber bug?

    - by beinstein
    I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. All of a sudden I'm now dumbfounded by an error. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set once specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 Has anyone ever encountered anything like this before? I've tried clean all targets, restarting everything, even changing the model to the relationship in question is a to-one instead of a to-many. Nothing makes any difference.

  • The difference between traditional DLL and COM DLL.

    - by smwikipedia
    I am currently studying COM. I found that COM DLL is kind of built upon the traditional DLL infrastructure. When we build COM DLLs, we still rely on the traditional DLL export methods to lead us to the internal COM co-classes. If COM is for component reusing at the binary level, I think the traditional DLL can achieve the same thing. They both expose functions, they are both binary, so what's the point of turning to COM approach? Currently, I have the feeling that the traditional DLL expose methods in a "flat" manner, while the COM DLL expose methods in an "OOP" hierarchy manner. And the OOP manner seems to be a better approach. Could this be the reason why COM prevails? Many thanks.

  • Bitmapdata heavy usage - memory disaster (spark/FB4)

    - by keyle
    I've got a flex component which works pretty well but unfortunately turns into a disaster once used in a datagroup item renderer of about 40-50 items. Essentially it uses bitmapdata to take screenshot of a fully-rendered webpage in mx:HTML (this version of webkit rocks btw, miles better than flex 3). The code is pretty self-explanatory I think. http://noben.org/show/PageGrabber.mxml I've optimized it all I could, browsed, search for answers and already trimmed it down a lot, I'm desparate to reduce the memory usage (about 600mb after 100 draw) The Garbage collector has little effect. Thanks! Nic
