  • Endless saving of CoreData Context

    - by Robert
    Sometimes I noticed that a 'save:' operation an a ManagedObjectContext never returns and consumes 100% CPU. I'm using an SQL Store in a GarbageCollected environment (Mac OS X 10.6.3). The disk activity shows about 700 KB/s writing. While having a look at the folder that contains the sqlite database file the "-journal" file appears and disappears, appears and disappears, ... This is part of the call graph from the process analysis: 2203 -[NSManagedObjectContext save:] 1899 -[NSPersistentStoreCoordinator(_NSInternalMethods) executeRequest:withContext:] 1836 -[NSSQLCore executeRequest:withContext:] 1836 -[NSSQLCore saveChanges:] 1479 -[NSSQLCore performChanges] ... 335 -[NSSQLCore recordChangesInContext:] ... 20 -[NSSQLCore rollbackChanges] ... 2 -[NSSQLCore prepareForSave:] ... 62 -[NSPersistentStoreCoordinator(_NSInternalMethods) _checkRequestForStore:originalRequest:andOptimisticLocking:] ... 1 -[NSPersistentStore(_NSInternalMethods) _preflightCrossCheck] ... 184 -[NSMergePolicy resolveConflicts:] ... 120 -[NSManagedObjectContext(_NSInternalChangeProcessing) _prepareForPushChanges:] ... Everything a happening in the main GUI thread. Any ideas what I can to do to resolve the problem?

  • ORM Against a Service-Wrapped Data Source

    - by blaster
    We are tasked with migrating an existing set of entities (currently POCOs persisted with NHibernate against an MSSQL database) to now persist to some kind of web service (yet to be built, either RESTful or SOAP-based, and that we control). I like how NHibernate encapsulates the persistence concerns and lets us maintain a logic-rich, persistence-agnostic domain model. Is there any way to make NHibernate talk to a web service at the back end instead of a SQL database directly? In other words, can "service instead of SQL database" be treated as a persistence implementation detail and allow us to continue to use NHibernate? Am I asking the right question? :)

  • Redirect to prevent dup submission...but then you loose existing data

    - by coffeeaddict
    Here's the scenario User is on your checkout.aspx page Somewhere in the process, when clicking the pay button, you redirect the user to an intermediate page (before the confirmation page) to do some other logic. That intermediate page performs whatever logic based on a querystring flag you sent with the redirect from the checkout page This intermediate page also serves as an error page. So if any logic in the intermediatePage.aspx.cs fails I'm setting a message to be displayed on this page to the user If I refresh, that querystring value is still in the url..hence when it hits my Page_Load again, then the server-side logic is called & run again and I don't want this to happen The avoid this behavior/problem, the logical next step is to do a redirect back to the same page if they refresh (not sure how you'd catch that) to get rid of that querystring But when you redirect back to the same page your error message is gone, lost in the redirect therefore you end up showing them the same page but all values for the error message are now gone I do not want to solve this with Javascript either. I am not sure the best way to handle this.

  • Get data from database with two conditions in one list

    - by Kreeki
    Hi coders out there, I'm new to this. I have a (sqlite3, but with ActiveRecord it doesn't matter) table called Messages and a model called Message. I want to find all messages in database that have user_id or reciever_id equal to the object user and his attribute id (for short user.id). I know it's probably just one simple line of code, but I wanna do it the right "rails" way and I don't have much experience with this. I'm using Rails 3. Thanks for any help. Cheers

  • Passing User Data with SetTimer

    - by GJ
    I am calling SetTimer in a function of a Class. SetTimer(NULL, 0, 10000, (TIMERPROC) TimerCallBack); Where TimerCallBack is: static VOID CALLBACK TimerCallBack(HWND, UINT, UINT, DWORD) Now my need is to call one of the method of class which initiated timer, since TimerCallBack is static it has no access to the class object anymore. I cant find any way to pass object pointer along with the SetTimer so that I can receive it back on Callback function. Is there any other way to achieve this, if its not supported using SetTimer then which other way I can implement this.

  • Information Modeling

    - by Betamoo
    The sensor module in my project consists of a rotating camera, that collects noisy information about moving objects in the surrounding environment. The information consists of distance, angle and relative change of the moving objects.. The limiting view range of the camera makes it essential to rotate the camera periodically to update environment information... I was looking for algorithms / ways to model these information, in order to be able to guess / predict / learn motion properties of these object.. My current proposed idea is to store last n snapshots of each object in a queue. I take weighted average of positions and velocities of moving object, but I think it is a poor method... Can you state some titles that suit this case? Thanks

  • handling matrix data in python

    - by Ovisek
    I was trying to progressively subtract values of a 3D matrix. The matrix looks like: ATOM 1223 ZX SOD A 11 2.11 -1.33 12.33 ATOM 1224 ZY SOD A 11 -2.99 -2.92 20.22 ATOM 1225 XH HEL A 12 -3.67 9.55 21.54 ATOM 1226 SS ARG A 13 -6.55 -3.09 42.11 ... here the last three columns are representing values for axes x,y,z respectively. now I what I wanted to do is, take the values of x,y,z for 1st line and subtract with 2nd,3rd,4th line in a iterative way and print the values for each axes. I was using: for line in map(str.split,inp): x = line[-3] y = line[-2] z = line[-1] for separating the values, but how to do in iterative way. should I do it by using Counter.

I am sure I am doing something wrong here.

  • WPF Databinding and Styling based on Data in an item in an IList

    - by Nate Bross
    I have a ListBox bound to a list of Items (for arguement, lets say its got a string and two dates Entered and Done). I would like to make the background color of items in the ListBox have a gray color if the Done DateTime is != DateTime.MinValue. Edit: Should I make a converter? and convert DateTime to a Brush based on the value of the DateTime? Is something like this my best option? or is there a simple Xaml snippet I could use? [ValueConversion(typeof(DateTime), typeof(Brush))] class MyConverter : IValueConverter { ... }

  • Jquery push data to the good row.

    - by marharépa
    Hi! This is my big problem. This script put the information to a table. function handleAccountFeed(result) { var entries = result.feed.getEntries(); var outputTable = ['<table><tr>', '<th>Account Name</th>', '<th>Profile Name</th>', '<th>Profile ID</th>', '<th>Table Id</th></tr>']; for (var i = 0, entry; entry = entries[i]; ++i) { var row = [ entry.getPropertyValue('ga:AccountName'), entry.getTitle().getText(), entry.getPropertyValue('ga:ProfileId'), entry.getTableId().getValue() ].join('</td><td>'); outputTable.push('<tr><td>', row, '</td></tr>'); } outputTable.push('</table>'); document.getElementById('outputDiv').innerHTML = outputTable.join(''); } I've got an own SMARTY template, which makes a table: <table id="stuffs"> <tbody> {section name=i loop=$ownsites} <tr><td>{$ownsites[i].id}</td><td>{$ownsites[i].domain}</td><td>PLACE</td></tr> {/section} <tbody> </table> I'd like to put the TableId (getTableId().getValue()) to that row's PLACE where {$ownsites[i].domain} is equal to the jquery row's Title (getTitle().getText()) How can i do this within this jQuery script?

  • actionscript 3 website load movieclips (frames) from library

    - by steve
    Here is my current code that doesn't function: import flash.display.*; import fl.transitions.*; import flash.events.MouseEvent; stop(); var contentBox:MovieClip = new MovieClip(); contentBox.width = 400; contentBox.height = 500; contentBox.x = 400; contentBox.y = 0; var closeBtn:close_btn = new close_btn(); closeBtn.x = 850; closeBtn.y = 15; var bagLink:MovieClip = new bag_link_mc(); bagLink.x = 900; bagLink.y = 0; menu_bag_button.addEventListener(MouseEvent.CLICK, bagClick); function bagClick(event:MouseEvent):void{ if(MovieClip(root).currentFrame == 835) { } else { MovieClip(root).addChild (contentBox); MovieClip(root).contentBox.addChild (bagLink); MovieClip(root).contentBox.addChild (closeBtn); MovieClip(root).gotoAndPlay(806); } } closeBtn.addEventListener(MouseEvent.CLICK, closeBag); function closeBag (event:MouseEvent):void{ MovieClip(root).removeChild(contentBox); MovieClip(root).gotoAndPlay(850); } I don't know ActionScript at all, so this may be the complete wrong way of approaching it. The setup is as follows: site loads, there's a big menu in the center (frame 805). When you click on a menu item from there, the whole menu moves to the side, and the right side I want a "contentBox" movieclip, filled with "bagLink" (which is site content) and to have a close button (closeBtn.) It also needs to know that if you click the same link again on the left side that it doesn't reanimate, it just stays (which I achieved with the "if" statement.) Finally, if someone clicks another link, it needs to clear "contentBox" and refill it with whatever movieClip that was clicked. I know this is a lot to ask, but I'm in dire need of help as this is due on Wednesday...

  • Data Validation for Random varying Phone Numbers

    - by baron
    I am storing phone numbers of varying lengths in my WPF (C#, VS 08) App. I store them as strings. My question is about my method AddNewPhoneNo(string phoneNo). In this method, I use Int.TryParse to validate the incoming number (i.e. not null, is numeric...). I've since realized this is probably not the best way to do this, because then I am limited to a number which is ± 2147483647. Definetly this is not always the case with phone numbers. What is a good, easy way to validate phone numbers? I guess the basic rules would be as follows: All numeric All positive Upto 25 chars (could be more, but this will to do for time being) Can't thing if theres any more rules at the moment, that's probably it.

  • Data mixing SQL Server

    - by Pythonizo
    I have three tables and a range of two dates: Services ServicesClients ServicesClientsDone @StartDate @EndDate Services: ID | Name 1 | Supervisor 2 | Monitor 3 | Manufacturer ServicesClients: IDServiceClient | IDClient | IDService 1 | 1 | 1 2 | 1 | 2 3 | 2 | 2 4 | 2 | 3 ServicesClientsDone: IDServiceClient | Period 1 | 201208 3 | 201210 Period = YYYYMM I need to insert into ServicesClientsDone the months range from @StartDate up @EndDate. I have also a temporary table (#Periods) with the following list: Period 201208 201209 201210 The query I need is to give me back the following list: IDServiceClient | Period 1 | 201209 1 | 201210 2 | 201208 2 | 201209 2 | 201210 3 | 201208 3 | 201209 4 | 201208 4 | 201209 4 | 201210 Which are client services but the ranks of the temporary table, not those who are already inserted This is what i have: Table periods: DECLARE @i int DECLARE @mm int DECLARE @yyyy int, DECLARE @StartDate datetime DECLARE @EndDate datetime set @EndDate = (SELECT GETDATE()) set @StartDate = (SELECT DATEADD(MONTH, -3,GETDATE())) CREATE TABLE #Periods (Period int) set @i = 0 WHILE @i <= DATEDIFF(MONTH, @StartDate , @EndDate ) BEGIN SET @mm= DATEPART(MONTH, DATEADD(MONTH, @i, @FechaInicio)) SET @yyyy= DATEPART(YEAR, DATEADD(MONTH, @i, @FechaInicio)) INSERT INTO #Periods (Period) VALUES (CAST(@yyyy as varchar(4)) + RIGHT('00'+CONVERT(varchar(6), @mm), 2)) SET @i = @i + 1; END Relation between ServicesClients and Services: SELECT s.Name, sc.IDClient FROM Services JOIN ServicesClients AS sc ON sc.IDService = s.ID Services already done and when: SELECT s.Name, scd.Period FROM Services JOIN ServicesClients AS sc ON sc.IDService = s.ID JOIN ServicesClientsDone AS scd ON scd.IDServiceClient = sc.IDServiceClient
