  • Flex - Cancel drag operation via keyboard

    - by Tom
    Hello I would like to be able to cancel a drag operation with the Escape key. The following did not work so far: calling stopDrag() on the component -- nothing happens calling DragManager.acceptDragDrop(null) -- nothing happens calling mx_internal function DragManager.endDrag() -- drag partly stops, the drag proxy image disappears but now the drop indicator shows at row 0, and also there's a null error when finally releasing the mouse Anybody else had any luck with this? Thanks!

  • Android hidden title bar comes back

    - by kasplurpo
    When my app starts, the title bar is hidden. However, if I leave the app and then return (minimize or phone goes to sleep), there is a blank bar inserted at the top. Is this an intentional feature? How can I prevent it? It seems that the bar goes away after I press the menu key. This is the relevant line in the manifest file: android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" Thanks

  • LINQ Group By to project into a non-anonymous type?

    - by vikp
    Hi, I have the following LINQ example: var colorDistribution = from product in ctx.Products group product by product.Color into productColors select new { Color = productColors.Key, Count = productColors.Count() }; All this works and makes perfect sense. What I'm trying to achieve is to group by into a strong type instead of anonymous type. For example I have a ProductColour class and I would like to Group into a List<ProductColour> Is this possible? Thank you

  • Connection hangs after time of inactivity

    - by Sinuhe
    In my application, Spring manages connection pool for database access. Hibernate uses these connections for its queries. At first glance, I have no problems with the pool: it works correctly with concurrent clients and a pool with only one connection. I can execute a lot of queries, so I think that I (or Spring) don't leave open connections. My problem appears after some time of inactivity (sometimes 30 minutes, sometimes more than 2 hours). Then, when Hibernate does some search, it lasts too much. Setting log4j level to TRACE, I get this logs: ... 18:27:01 DEBUG nsactionSynchronizationManager - Retrieved value [org.springframework.orm.hibernate3.SessionHolder@99abd7] for key [org.hibernate.impl.SessionFactoryImpl@7d2897] bound to thread [http-8080-Processor24] 18:27:01 DEBUG HibernateTransactionManager - Found thread-bound Session [org.hibernate.impl.SessionImpl@8878cd] for Hibernate transaction 18:27:01 DEBUG HibernateTransactionManager - Using transaction object [org.springframework.orm.hibernate3.HibernateTransactionManager$HibernateTransactionObject@1b2ffee] 18:27:01 DEBUG HibernateTransactionManager - Creating new transaction with name [com.acjoventut.service.GenericManager.findByExample]: PROPAGATION_REQUIRED,ISOLATION_DEFAULT 18:27:01 DEBUG HibernateTransactionManager - Preparing JDBC Connection of Hibernate Session [org.hibernate.impl.SessionImpl@8878cd] 18:27:01 TRACE SessionImpl - setting flush mode to: AUTO 18:27:01 DEBUG JDBCTransaction - begin 18:27:01 DEBUG ConnectionManager - opening JDBC connection Here it gets frozen for about 2 - 10 minutes. But then continues: 18:30:11 DEBUG JDBCTransaction - current autocommit status: true 18:30:11 DEBUG JDBCTransaction - disabling autocommit 18:30:11 TRACE JDBCContext - after transaction begin 18:30:11 DEBUG HibernateTransactionManager - Exposing Hibernate transaction as JDBC transaction [jdbc:oracle:thin:@212.31.39.50:30998:orcl, UserName=DEVELOP, Oracle JDBC driver] 18:30:11 DEBUG nsactionSynchronizationManager - Bound value [org.springframework.jdbc.datasource.ConnectionHolder@843a9d] for key [org.apache.commons.dbcp.BasicDataSource@7745fd] to thread [http-8080-Processor24] 18:30:11 DEBUG nsactionSynchronizationManager - Initializing transaction synchronization ... After that, it works with no problems, until another period of inactivity. IMHO, it seems like connection pool returns an invalid/closed connection, and when Hibernate realizes that, ask another connection to the pool. I don't know how can I solve this problem or things I can do for delimiting it. Any help achieving this will be appreciate. Thanks. EDIT: Well, it finally was due a firewall rule. Database detects the connection is lost, but pool (dbcp or c3p0) not. So, it tries to query the database with no success. What is still strange for me is that timeout period is very variable. Maybe the rule is specially strange or firewall doesn't work correctly. Anyway, I have no access to that machine and I can only wait for an explanation. :(

  • Get the count of items in a GroupBy Linq-to-sql Query?

    - by Curtis White
    I have a groupby that I groups all elements. I can see the items are there in LinqPad but can't find a way to get the count. Here is what I have so far: SurveyResponses.Where( q = q.QuestionId == 4).GroupBy(q = q.AnswerNumeric).Where( g = g.Key == 1) In Linq Pad I can see there are 4 items in this query. If I do Count it returns 1. I've tried, ToList().Count, Select(x = x).Count, etc.

  • using onDelete with Doctrine 2

    - by tamir
    I can't get the onDelete to work in Doctrine2 (with YAML Mapping). I tried this relation in my Product class: oneToOne: category: targetEntity: Category onDelete: CASCADE But that doesn't work.. EDIT: I've set the ON DELETE: CASCADE manually in the database imported the YAML mapping with doctrine:mapping:import, emptied the database updated it from the schema with doctrine:schema:update and got no ON DELETE in the foreign key.. so looks like even Doctrine doesn't know how to do it lol..

  • JPA entity design / cannot delete entity

    - by timaschew
    I though its simple what I want, but I cannot find any solution for my problem. I'm using playframework 1.2.3 and it's using Hibernate as JPA. So I think playframework has nothing to do with the problem. I have some classes (I omit the nonrelevant fields) public class User { ... } public class Task { public DataContainer dataContainer; } public class DataContainer { public Session session; public User user; } public class Session { ... } So I have association from Task to DataContainer and from DataContainer to Sesssion and the DataContainer belongs to a User. The DataContainers can have always the same User, but the Session have to be different for each instance. And the DataContainer of a Task have also to be different in each instance. A DataContainer can have a Sesesion or not (it's optinal). I use only unidirectional assoc. It should be sufficient. In other words: Every Task must has one DataContainer. Every DataContainer must has one/the same User and can have one Session. To create a DB schema I use JPA annotations: @Entity public class User extends Model { ... } @Entity public class Task extends Model { @OneToOne(optional = false, cascade = CascadeType.ALL) public DataContainer dataContainer; } @Entity public class DataContainer extends Model { @OneToOne(optional = true, cascade = CascadeType.ALL) public Session session; @ManyToOne(optional = false, cascade = CascadeType.ALL) public User user; } @Entity public class Session extends Model { ... } BTW: Model is a play class and provides the primary id as long type. When I create some for each entity a object and 'connect them', I mean the associations, it works fine. But when I try to delete a Session, I get a constraint violation exception, because a DataContainer still refers to the Session I want to delete. I want that the Session (field) of the DataContainer will be set to null respectively the foreign key (session_id) should be unset in the database. This will be okay, because its optional. I don't know, I think I have multiple problems. Am I using the right annotation @OneToOne ? I found on the internet some additional annotation and attributes: @JoinColumn and a mappedBy attribute for the inverse relationship. But I don't have it, because its not bidirectional. Or is a bidirectional assoc. essentially? Another try was to use @OnDelete(action = OnDeleteAction.CASCADE) the the contraint changed from NO ACTIONs when update or delete to: ADD CONSTRAINT fk4745c17e6a46a56 FOREIGN KEY (session_id) REFERENCES annotation_session (id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE CASCADE; But in this case, when I delete a session, the DataContainer and User is deleted. That's wrong for me. EDIT: I'm using postgresql 9, the jdbc stuff is included in play, my only db config is db=postgres://app:app@localhost:5432/app

  • Uploading file to DropBox causing UnlinkedException

    - by Boardy
    I am currently working on android project and trying to enable DropBox functionality. I've selected the access type to App Only, and I can successfully authenticate and it creates an Apps directory and inside that creates a directory with the name of my app. When I then try to put a file in the DropBox directory it goes into the DropBoxException catch and in the logcat prints com.dropbox.client2.exception.DropboxUnlinkedException. I've done a google and from what I've seen this happens if the apps directory has been deleted and so authentication is required to be re-done, but this isn't the case, I have deleted it and I am putting the file straight after doing the authentication. Below is the code that retrieves the keys and stores the file on dropbox. AccessTokenPair tokens = getTokens(); UploadFile uploadFile = new UploadFile(context, common, this, mDBApi); uploadFile.execute(mDBApi); Below is the code for the getTokens method (don't think this would help but you never know) private AccessTokenPair getTokens() { AccessTokenPair tokens; SharedPreferences prefs = context.getSharedPreferences("prefs", 0); String key = prefs.getString("dropbox_key", ""); String secret = prefs.getString("dropbox_secret", ""); tokens = new AccessTokenPair(key, secret); return tokens; } Below is the class that extends the AsyncTask to perform the upload class UploadFile extends AsyncTask<DropboxAPI<AndroidAuthSession>, Void, bool> { Context context; Common common; Synchronisation sync; DropboxAPI<AndroidAuthSession> mDBApi; public UploadFile(Context context, Common common, Synchronisation sync, DropboxAPI<AndroidAuthSession> mDBApi) { this.context = context; this.common = common; this.sync = sync; this.mDBApi = mDBApi; } @Override protected bool doInBackground(DropboxAPI<AndroidAuthSession>... params) { try { File file = new File(Environment.getExternalStorageDirectory() + "/BoardiesPasswordManager/dropbox_sync.xml"); FileInputStream inputStream = new FileInputStream(file); Entry newEntry = mDBApi.putFile("android_sync.xml", inputStream, file.length(), null, null); common.showToastMessage("Successfully uploade Rev: " + newEntry.rev, Toast.LENGTH_LONG); } catch (IOException ex) { Log.e("DropBoxError", ex.toString()); } catch (DropboxException e) { Log.e("DropBoxError", e.toString()); e.printStackTrace(); } return null; } I have no idea why it would display the UnlinkedException so any help would be greatly appreciated.

  • java multipart POST library

    - by tom
    Is there a multipart POST library out there that achieve the same effect of doing a POST from a html form? for example - upload a file programmingly in Java versus upload the file using a html form. And on the server side, it just blindly expect the request from client side to be a multipart POST request and parse out the data as appropriate. Has anyone tried this? specifically, I am trying to see if I can simulate the following with Java The user creates a blob by submitting an HTML form that includes one or more file input fields. Your app sets blobstoreService.createUploadUrl() as the destination (action) of this form, passing the function a URL path of a handler in your app. When the user submits the form, the user's browser uploads the specified files directly to the Blobstore. The Blobstore rewrites the user's request and stores the uploaded file data, replacing the uploaded file data with one or more corresponding blob keys, then passes the rewritten request to the handler at the URL path you provided to blobstoreService.createUploadUrl(). This handler can do additional processing based on the blob key. Finally, the handler must return a headers-only, redirect response (301, 302, or 303), typically a browser redirect to another page indicating the status of the blob upload. Set blobstoreService.createUploadUrl as the form action, passing the application path to load when the POST of the form is completed. <body> <form action="<%= blobstoreService.createUploadUrl("/upload") %>" method="post" enctype="multipart/form-data"> <input type="file" name="myFile"> <input type="submit" value="Submit"> </form> </body> Note that this is how the upload form would look if it were created as a JSP. The form must include a file upload field, and the form's enctype must be set to multipart/form-data. When the user submits the form, the POST is handled by the Blobstore API, which creates the blob. The API also creates an info record for the blob and stores the record in the datastore, and passes the rewritten request to your app on the given path as a blob key.

  • Java equivalent of C++ std::map?

    - by Rudiger
    I'm looking for a Java class with the characteristics of C++ std::map's usual implementation (as I understand it, a self-balancing binary search tree): O(log n) performance for insertion/removal/search Each element is composed of a unique key and a mapped value Keys follow a strict weak ordering I'm looking for implementations with open source or design documents; I'll probably end up rolling my own support for primitive keys/values. This question's style is similar to: Java equivalent of std::deque, whose answer was "ArrayDeque from Primitive Collections for Java".

  • Oracle : Identifying duplicates in a table without index

    When I try to create a unique index on a large table, I get a unique contraint error. The unique index in this case is a composite key of 4 columns. Is there an efficient way to identify the duplicates other than : select col1, col2, col3, col4, count() from Table1 group by col1, col2, col3, col4 having count() 1 The explain plan above shows full table scan with extremely high cost, and just want to find if there is another way.
