• Override default behavior of SPACE key in .net WinForms ListView

  - by Axarydax

  Hello, I'd like to implement some custom behavior of Space key in a ListView. Basically I'd like to toggle selected status of the item under cursor - that should be fairly simple this.FocusedItem.Selected = !this.FocusedItem.Selected; but alas, it also does the default action, which is to select the focused item. This way I am unable to 'unselect' the focused item. I've looked for similar problems and they suggest using PreviewKeyDown event, in which I would process the key and disallow the ListView to do its default action. But the PreviewKeyDown event argument has no "handled" property, so I cannot 'eat' this key.

• How do I insert into a unique key into a table?

  - by Ben McCormack

  I want to insert data into a table where I don't know the next unique key that I need. I'm not sure how to format my INSERT query so that the value of the Key field is 1 greater than the maximum value for the key in the table. I know this is a hack, but I'm just running a quick test against a database and need to make sure I always send over a Unique key. Here's the SQL I have so far: INSERT INTO [CMS2000].[dbo].[aDataTypesTest] ([KeyFld] ,[Int1]) VALUES ((SELECT Max([KeyFld]) FROM [dbo].[aDataTypesTest]) + 1 ,1) which errors out with: Msg 1046, Level 15, State 1, Line 5 Subqueries are not allowed in this context. Only scalar expressions are allowed. I'm not able to modify the underlying database table. What do I need to do to ensure a unique insert in my INSERT SQL code?

• JSF Conditional formatting for onmouseover and such attributes.

  - by Ben

  Hi, I'm trying to format a panelgrid according to a value in the backing bean. I'm currently trying this as the value of the onmouseover attribute: this.className=#{(actions.currentlySelectedActionButton == 0)?'actionButton actionButtonChosen':'actionButton'}; whereas the CSS looks like this: (the relevant parts): .actionButton { width: 100%; height: 20px; border: thin solid #000; cursor:default; } .actionButtonChosen { background-color: blue; } It's not working. Anyone spotting the error would help me greatly. Thanks!

• Permission denial to read from emailprovider in android

  - by Ambika

  Hello Everyone, I've the problem when I want to read "com.android.email.provider" to get email accounts. Here is my code to retrieve the account : Cursor c = null; Uri CONTENT_URI = Uri.parse("content://com.android.email.provider/account"); String RECORD_ID = "_id"; String[] ID_PROJECTION = new String[] {RECORD_ID }; c = getContentResolver().query(CONTENT_URI,ID_PROJECTION,null, null, null); I get a security exception: java.lang.SecurityException: Permission Denial: reading com.android.email.provider.EmailProvider uri content://com.android.email.provider/account from pid=278, uid=10003 requires com.android.email.permission.ACCESS_PROVIDER I want to know the account is created or not in some other app. Is there any other way to resolve this so that I can read from the provider. I have also tried by adding the permission in manifest: That dint not help. Any solution would be greatly appreciated. Thanks in advance

• Managing a difficult manager

  - by griegs

  I have a situation here at work. We are redeveloping our basic architecture across the entire company. Currently we have the following hierarchy; SQL Database <= Stored Procs not allowed. nHibernate Classes to convert nHibernate into our own objects Web Service <= for all external and [internal] calls. Class to take objects from Web Service and back into our own objects and then… Normal nTier application architecture such as Data Transformation Layer, Business layer etc. Within the database, when we are writing a hierarchy of objects to the database, say for example; Order Person Details Address Product Other We need to serialise the object and save it, in its entirety, to an image field in a table. No attempt has been made to store the objects in their own tables so that we can do useful stuff like report on it. This is an architecture that was implemented [way] before I started and as you can probably appreciate, is a complete nightmare not to mention slow as a wet weekend. We’re not even allowed to have stored procs within SQL server because in my boss’s last job they had a hundred or so and he had a problem identifying them all so therefore all stored procs are the devil. Now the same person that developed the above architecture has developed the new one. It came as no surprise that he’s essentially used the same framework only now it’s using DotNet 3.5 with interfaces and generics. We still have to go through web services, still need to serialise (everything), still not allowed to use stored procs etc. In fact, we’re only barely able to bang two rocks together here. He says to us that the framework is open for discussion but when you discuss it, unless you approve of his design, you are told flatly “No”. He simply won’t listen to any other suggestions. Even when you show him demo applications of his proposed architecture v’s yours and he can see the speed difference, he still won’t take that on board. So I guess my question is, and I know others have experienced the same things out there, how do I get through to someone like this? How do you convince someone to ditch Web Services for internal calls and applications? How do you demonstrate, and make it stick, that stored procs are a better way to go than ad-hoc sql statements? This is killing me. I don’t want to repeat the mistakes of the past and I certainly don’t want to write code that I know is going to be slow and cumbersome. Help!

• Swipe gestures on Android ListView items

  - by Bartek

  I have a ListView populated by a ResourceCursorAdapter. I use the loaders mechanism to query a ContentProvider for list items. I detect swipe gestures on the list items to perform some actions on them. New items get added by a background service, so the list can change dynamically. Everything works fine, except when I start swiping and a database change occurs (as a result of the background service adding a new row). In such case the gesture is not detected properly. I noticed that ACTION_CANCEL is dispatched to the list item view and also that bindView is executed for all visible items. Inside the bindView method I only set some text - I don't change any listeners there. How can I make gestures work even when new items are being added by the background service? Perhaps there's a way to prevent the motion from being cancelled or I can pause database updates so they don't interrupt the gesture.

• Specify which row to return on SQLite Group By

  - by lozzar

  I'm faced with a bit of a difficult problem. I store all the versions of all documents in a single table. Each document has a unique id, and the version is stored as an integer which is incremented everytime there is a new version. I need a query that will only select the latest version of each document from the database. While using GROUP BY works, it appears that it will break if the versions are not inserted in the database in the order of version (ie. it takes the maximum ROWID which will not always be the latest version). Note, that the latest version of each document will most likely be a different number (ie. document A is at version 3, and document B is at version 6). I'm at my wits end, does anybody know how to do this (select all the documents, but only return a single record for each document_id, and that the record returned should have the highest version number)?

• Using Emacs for big big projects

  - by ignatius

  Hello, Maybe is a often repeated question here, but i can't find anything similar with the search. The point is that i like to use Emacs for my personal projects, usually very small applications using C or python, but i was wondering how to use it also for my work, in which we have project with about 10k files of source code, so is veeeery big (actually i am using source insight, that is very nice tool, but only for windows), questions are: Searching: Which is the most convenient way to search a string within the whole project? Navigating throught the function: I mean something like putting the cursor over a function, define, var, and going to the definition Refactoring Also if you have any experience with this and want to share your thoughts i will consider it highly interesting.

• Using Unity and interfaces, how do I create a concrete class that implements IDisposable

  - by Ryan ONeill

  I have an interface (IDbAccess) for a database access class so that I can unit test it using Unity. It all works fine in Unity and now I want to make the concrete database class implement IDisposable so that it closes the db connections. My problem is that Unity does not understand that my concrete class is disposable because the interface (IDbAccess) cannot implement another interface. So how can I write code like this (pseudo code) so that Unity is aware that it needs to dispose the class as soon as I am done? Using var MyDbAccessInstance = Unity.Resolve<IDbAccess> { } Thanks Ryan

• "The specified table does not exist" - for the administrator it does! Vista only issue

  - by Simon Nunn

  Hello, I've got a weird bug occurring in a compact database on a Vista deployment machine. Basically the sdf file seem to be schizophrenic. The client application get the entitled error when running as a user but not when I use run as administrator. I don't see this problem on my XP development machine. I installed management studio onto the deployment machine and opened two versions of the application, one as user and one as administrator. When I query: SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES I see 21 tables on the one and 26 on the other, and the administrator is seeing less tables. It turns out that the user version, with 26 rows, is a previous incarnation of this database. Any ideas on why this is happening?

• Faster bulk inserts in sqlite3?

  - by scubabbl

  I have a file of about 30000 lines of data I want to load into a sqlite3 database. Is there a faster way that generating insert statements for each line of data? The data is space delimited and maps directly to the sqlite3 table. Is there any sort of bulk insert method for adding volume data to a database? Has anyone devised some deviously wonderful way of doing this if it's not built in? I should preface this by asking is there a c++ way to do it from the API? Thanks.

• Should an event-sourced aggregate root have query access to the event sourcing repository?

  - by JD Courtoy

  I'm working on an event-sourced CQRS implementation, using DDD in the application / domain layer. I have an object model that looks like this: public class Person : AggregateRootBase { private Guid? _bookingId; public Person(Identification identification) { Apply(new PersonCreatedEvent(identification)); } public Booking CreateBooking() { // Enforce Person invariants var booking = new Booking(); Apply(new PersonBookedEvent(booking.Id)); return booking; } public void Release() { // Enforce Person invariants // Should we load the booking here from the aggregate repository? // We need to ensure that booking is released as well. var booking = BookingRepository.Load(_bookingId); booking.Release(); Apply(new PersonReleasedEvent(_bookingId)); } [EventHandler] public void Handle(PersonBookedEvent @event) { _bookingId = @event.BookingId; } [EventHandler] public void Handle(PersonReleasedEvent @event) { _bookingId = null; } } public class Booking : AggregateRootBase { private DateTime _bookingDate; private DateTime? _releaseDate; public Booking() { //Enforce invariants Apply(new BookingCreatedEvent()); } public void Release() { //Enforce invariants Apply(new BookingReleasedEvent()); } [EventHandler] public void Handle(BookingCreatedEvent @event) { _bookingDate = SystemTime.Now(); } [EventHandler] public void Handle(BookingReleasedEvent @event) { _releaseDate = SystemTime.Now(); } // Some other business activities unrelated to a person } With my understanding of DDD so far, both Person and Booking are seperate aggregate roots for two reasons: There are times when business components will pull Booking objects separately from the database. (ie, a person that has been released has a previous booking modified due to incorrect information). There should not be locking contention between Person and Booking whenever a Booking needs to be updated. One other business requirement is that a Booking can never occur for a Person more than once at a time. Due to this, I'm concerned about querying the query database on the read side as there could potentially be some inconsistency there (due to using CQRS and having an eventually consistent read database). Should the aggregate roots be allowed to query the event-sourced backing store for objects (lazy-loading them as needed)? Are there any other avenues of implementation that would make more sense?

• Preserving text formatting for dynamic website

  - by Mohit

  Hello Folks, I am facing a problem while creating a dynamic website. I am building it for some pharma company, which have many products. The problem is, every product have different sections of description, and have to be formatted differently. I wanted to store all the product descriptions in the database, but at the same time preserve the formatting of each description. I also plan to provide an admin interface, where they could edit the product information themselves. I could use Joomla or any other CMS for that purpose, but i wanted to know if i want to build such a system of my own, where i could format the text in an editor and them save that thing into database and when i retrieve it, i get the same formatting. How could i do this? Also i wanted to do this in PHP. Thanks -- Mohit

• MySQL auto increment

  - by mouthpiec

  Hi, I have table with an auto-increment field, but I need to transfer the table to another table on another database. Will the value of field 1 be 1, that of field 2 be 2, etc? Also in case the database get corrupted and I need to restore the data, will the auto-increment effect in some way? will the value change? (eg if the first row, id (auto-inc) = 1, name = john, country = UK .... will the id field remain 1?) I am asking because if other table refer to this value, all data will get out of sync if this field change.

• How can I run Octave under Emacs on Windows (Vista)?

  - by Arlie Capps

  Hello, I installed Emacs 23.1.1 and Octave 3.2.3 on my computer running Vista. To make Emacs find Octave, and to make Octave's prompt what Emacs expects, I added the following to the end of my .emacs file: (setq inferior-octave-program "C:/Octave/3.2.3_gcc-4.4.0/bin/octave-3.2.3.exe") (setq inferior-octave-startup-args (list "--eval" "PS1('octave:\# ');" "--persist")) When I do M-x run-octave, I get the "wait" cursor. I can see (using procexp) that Octave starts up as a child process to Emacs, but Emacs and Octave do not talk. Any insight would be much appreciated.

• How to add a URL and Buttons on top of an Existing Header Image

  - by tonsils

  Hi, 1) I have a header jpeg image that spans a width of 996px that has a square logo to the left of this header. My question is that I would like to use this square logo section only and place a ahref tag so that when the user hover's over this section only, the cursor changes to a hand pointer and the user will be redirected back to the landing page. Any assistance on this would be great. 2) On this same image, I would also like to place two buttons with rollover effects, so when the user hovers over the buttons, the rollover effect takes control and then would like these buttons to also point to a href url. Again, any help on this would be appreciated. Thanks.

• How do I prevent duplicate entrys to mySQL?

  - by ggfan

  On my site, I have a form that users fill out to become a member. They fill out name, bday, email, etc. Then when they click submit, the data gets into mySQL. But sometimes when a user clicks submit many times or refreshes the page, the data gets inputted to the database more than once. How can I prevent this? Is there a code I can use to only let one set of data get into the database? This is also a problem in my comment section. I allow uses to put comments on people's profiles. But when they abuse the refresh button or submit button, I get like 10 of the same comments. Thanks.

• Command-line options for HH and opening CHM Windows Help Files

  - by Jeromy Anglim

  I'd like to be able to write Inquisit scripts in Vim. In the standard Inquisit application for writing scripts, I can press F1 and it brings up help on the topic related to the word under the cursor. I'd like to set up the same functionality through Vim. The help file for Inquisit is stored in a Windows .CHM file. I figured there must be a set of command-line options for doing a keyword search in a chm file, but I haven't been able to find a complete list of the command-line options, presumably for HH.exe. I did find this page with a few pointers, but it does not have a full listing of command-line options. I also found this discussion on AutoHotKey discussion board. It mentions keyhh. I also just found a vimscript designed to do exactly what I want Questions: Is there a complete list of command-line options for HH.exe? Is there a better way of going about what I am trying to do?

• IDataServiceMetadataProvider / ResourceType.... what for dynamic types with no CLR type?

  - by TomTom

  Hello, I try to expose a database via ADO RIA for which we have only an ODBC based interface. The "database" is a server and new elements are developped all the time, so I would like the server to check metadata at start (using the odbc schema methods) and then expose what he finds via RIA services.... clients can the nregenerate when they need access to new elements. As such, I dont ahve any CLR types for all the tabled developped. ResourceType tableType = new ResourceType( typeof(object), ResourceTypeKind.EntityType, null, "Martini", table_name, false ); tableType.CanReflectOnInstanceType = false; I can somehow not put in NULl as CLR element type, and entering typeof(object) seems to result in reflection errors when trying to access the properties. Any documentation on how to do that? I dont really want to get into having types... though if I have to, I probably will dynamically generate some via bytecode emit.

• Qt - drag and drop with graphics view framework

  - by David Davidson

  I'm trying to make a simple draggable item using the graphics framework. Here's the code for what I did so far: Widget class: class Widget : public QWidget { Q_OBJECT public: Widget(QWidget *parent = 0); ~Widget(); }; Widget::Widget(QWidget *parent) : QWidget(parent) { DragScene *scene = new DragScene(); DragView *view = new DragView(); QHBoxLayout *layout = new QHBoxLayout(); DragItem *item = new DragItem(); view->setAcceptDrops(true); scene->addItem(item); view->setScene(scene); layout->addWidget(view); this->setLayout(layout); } Widget::~Widget() { } DragView class: class DragView : public QGraphicsView { public: DragView(QWidget *parent = 0); }; DragView::DragView(QWidget *parent) : QGraphicsView(parent) { setRenderHints(QPainter::Antialiasing); } DragScene class: class DragScene : public QGraphicsScene { public: DragScene(QObject* parent = 0); protected: void dragEnterEvent(QGraphicsSceneDragDropEvent *event); void dragMoveEvent(QGraphicsSceneDragDropEvent *event); void dragLeaveEvent(QGraphicsSceneDragDropEvent *event); void dropEvent(QGraphicsSceneDragDropEvent *event); }; DragScene::DragScene(QObject* parent) : QGraphicsScene(parent) { } void DragScene::dragEnterEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dragMoveEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dragLeaveEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dropEvent(QGraphicsSceneDragDropEvent *event){ qDebug() << event->pos(); event->acceptProposedAction(); DragItem *item = new DragItem(); this->addItem(item); item->setPos(event->pos()); } DragItem class: class DragItem : public QGraphicsItem { public: DragItem(QGraphicsItem *parent = 0); QRectF boundingRect() const; void paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget = 0); protected: void mouseDoubleClickEvent(QGraphicsSceneMouseEvent *event); void mouseMoveEvent(QGraphicsSceneMouseEvent *event); void mousePressEvent(QGraphicsSceneMouseEvent *event); void mouseReleaseEvent(QGraphicsSceneMouseEvent *event); }; DragItem::DragItem(QGraphicsItem *parent) : QGraphicsItem(parent) { setFlag(QGraphicsItem::ItemIsMovable); } QRectF DragItem::boundingRect() const{ const QPointF *p0 = new QPointF(-10,-10); const QPointF *p1 = new QPointF(10,10); return QRectF(*p0,*p1); } void DragItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget){ if(painter == 0) painter = new QPainter(); painter->drawEllipse(QPoint(0,0),10,10); } void DragItem::mouseDoubleClickEvent(QGraphicsSceneMouseEvent *event){ } void DragItem::mouseMoveEvent(QGraphicsSceneMouseEvent *event){ } void DragItem::mousePressEvent(QGraphicsSceneMouseEvent *event){ QMimeData* mime = new QMimeData(); QDrag* drag = new QDrag(event->widget()); drag->setMimeData(mime); drag->exec(); } void DragItem::mouseReleaseEvent(QGraphicsSceneMouseEvent *event){ } main.cpp instantiates a Widget and shows it. When I try to drag the circle, the app just creates another circle over the original one, regardless of where I release the drag. qDebug() in DragScene's dropEvent() shows QPointF(0,0) everytime the drag ends. I'm having a hard time trying to understand exactly what I have to do, which classes I should subclass, which methods needs to be overriden, to make this work. The documentation on this isn't very detailed. I'd like to know how to make this work, and if there's some other, more comprehensive resource to learn about the graphics view framework, besides the official documentation (which is excellent btw, but it would be great if there was a more detailed treatise on the subject). EDIT: Following badgerr's advice, I replaced item-pos() in DragScene::dropEvent() with item-scenePos(), now the drop event creates a new circle in the drop site, which is more or less what I wanted. But the original circle is still in place, and while the drag is in progress, the item doesn't follow the mouse cursor. The QGraphicsSceneDragDropEvent documentation says that pos() should return the cursor position in relation to the view that sent the event, which, unless I got it wrong, shouldn't be (0,0) all the time. Weird. I've read in a forum post that you can use QDrag::setPixMap() to show something during the drag, and in examples I've seen pictures being set as pixmaps, but how do I make the pixmap just like the graphics item I'm supposed to be dragging?

• Proper way to set class variables

  - by ensnare

  I'm writing a class to insert users into a database, and before I get too far in, I just want to make sure that my OO approach is clean: class User(object): def setName(self,name): #Do sanity checks on name self._name = name def setPassword(self,password): #Check password length > 6 characters #Encrypt to md5 self._password = password def commit(self): #Commit to database >>u = User() >>u.setName('Jason Martinez') >>u.setPassword('linebreak') >>u.commit() Is this the right approach? Should I declare class variables up top? Should I use a _ in front of all the class variables to make them private? Thanks for helping out.
