• Problem deleting record using Entity Framework and System.Data.SQLite

  - by jamone

  I have a SQLite DB that is set up so when I delete a Person the delete is cascaded. This works fine when I manually delete a Person (all records that reference the PersonID are deleted). But when I use Entity Framework to delete the Person I get an error: System.InvalidOperationException: The operation failed: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. When a change is made to a relationship, the related foreign-key property is set to a null value. If the foreign-key does not support null values, a new relationship must be defined, the foreign-key property must be assigned another non-null value, or the unrelated object must be deleted. I don't understand why this is occurring. My trigger is set to clean up all related objects before deleting the object it was told to delete. When I go into the model editor and check the properties of the relationship it shows no action for the OnDelete property. Why isn't this set correctly by pulling it from the DB? Here's the relivent SQL for my tables. CREATE TABLE [SomeTable] ( [SomeTableID] INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, [PersonID] INTEGER NOT NULL REFERENCES [Person](PersonID) ON DELETE CASCADE ) CREATE TABLE [Person] ( [PersonID] INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT )

• Why might changes be populated from one NSManagedObjectContext to another without an explicit merge?

  - by Mike Laurence

  I'm working on an object import feature that utilizes multiple threads/NSManagedObjectContexts, using http://www.mac-developer-network.com/columns/coredata/may2009/ as my guide (note that I am developing for iPhone). For some reason, when I save one of my contexts the other is immediately updated with the changes, even though I have commented out my calls to mergeChangesFromContextDidSaveNotification. Are there any reasons the contexts might be merging into one another without an explicit call? Here a log of what's going on: // 1.) Main context is saved with "Peter Gabriel" // 2.) Test context is created, begins with same contents as main context // 3.) Main context is inserted with "Spoon" // 4.) Test context is inserted with "Phoenix" // Contents at this point: CoreTest[4341:903] Artists in main context: ( "Peter Gabriel", "Spoon" ) CoreTest[4341:903] Artists in test context: ( "Peter Gabriel", "Phoenix" ) // 5.) testContext is saved // New contents of contexts: CoreTest[4341:903] Artists in main context: ( "Peter Gabriel", "Phoenix", "Spoon" ) CoreTest[4341:903] Artists in test context: ( "Peter Gabriel", "Phoenix" ) As you can see, the test context is saved midway through, and the main context suddenly has the new objects from the test context, even though I haven't performed the whole NSManagedObjectContextDidSaveNotification/mergeChangesFromContext combo. My understanding is that no changes will ever be merged unless done so explicitly... does anyone know what's going on here?

• No Business Data Connectivity Service associated with current web context error

  - by Rob

  I am running on a new dev setup for SharePoint 2010 and trying to setup some External Content types. I think that I have setup BCS correctly (since I see it running in the central administration). When I go into SharePoint designer 2010 and try to setup a new External Content Type, I get the following error: "There is no Business Connectivity Service associated with the current web context." Am I missing something with the configuration or why am I not able to setup a new External Content Type to point to my existing SQL database

• How to draw a 3D donut chart in OpenGL?

  - by paulbeesley

  I would like to draw a chart in OpenGL similar to the donut graph at the bottom-right of this example. I have experience with drawing 2D charts such as the main chart in the example but what confuses me about the one I want to draw is the correct type of primitive to use when drawing the 3D chart. I have considered using GL_QUAD_STRIP and GL_POLYGON but neither seem quite right for the task. Where should I begin? I will be using JOGL with Java to draw the chart, if that helps at all. Also, I don't necessarily need to extrude certain slices of the chart as shown in the example.

• How to avoid the refetch of records when paging button is clicked on the radgrid.

  - by Pravin

  Iam using the radgrid, in my web application. Iwant to avoid the refetch of records when paging button is clicked on the radgrid. I have a method SetTodaysAlerts which gets near about 100 records and binds to my radgrid. The page size of the radgrid is 10, hence First, Next, Previous and Last buttons are available. When I click the next button how can I avoid the re fetching of the records again. FYI: Iam using the radgrid_NeedDataSource event which does the datafetch again when any navigatin button is clicked on the radgrid.

• Load CoreData objects' string property into UIPickerView

  - by OscarTheGrouch

  Hello Currently I have an entity named "Events" in a CoreData app. "Events" has one string property named "eventName". In the -(void)viewDidLoad I am trying to Fetch all the "Events" objects and load their "eventName" by alphabetical order into a UIPickerView. The ultimate end goal is through the use of a textField, buttons and the pickerView being add new objects in and remove unwanted objects out. Basically turning the UIPickerView into a UITableView. Currently I am able to save objects to the CoreData store, but am not able to pull them/their properties out into the UIPickerView. I am willing and able to share the project source code to anyone who wants it, or is willing to look at it to help out. thanks Chris

• ASP.NET MVC Class level custom data-annotation and ModelState keys

  - by Neil

  Hi, I have custom class level validation attribute, inheriting from ValidationAttribute, on my model. How come it doesn't register a key in the ModelState when its IsValid is false? I can see the the error message in the ModelState.Values collection, but the ModelState.Keys collection only shows an empty string "". Can I provide a key for it - presumably this is because its not assigned to a property? I wanna be able to use ModelState.Remove in my controller to remove this error upon a certain condition, but I have no Key! Any ideas?

• Styling hyperlink button inside a data template in Silverlight

  - by cmaduro

  How do I change the visual state of a hyperlinkbutton inside a datatemplate? In short, what I'm doing is basically I'm trying to iterate of the hyperlinkbuttons and set their visual state to active or inactive according to the url. The hyperlink buttons are located inside the datatemplate of an itemscontrols itemsource that is bound to a List where link is my custom class for links. Is there a best practice for styling the active hyperlink in a silverlight nav app? What I am using is the approach of the boilerplate code.

In order to tidy this table up, I need to get this information as a date range rather than a row per day as it currently is. I can obviously do this with Min and Max aggregates easily but the ranges overlap and other business code expect non-overlapping ranges. I also tried to achieve this with self joins and row_number(), but without much success... Here is what I'm trying to achieve as the output: Product | StartDate | EndDate | Price ------------------------------------------- Apples | 01 Mar 2010 | 02 Mar 2010 | 4.90 Apples | 03 Mar 2010 | 03 Mar 2010 | 2.50 Apples | 05 Mar 2010 | 09 Mar 2010 | 4.90 Apples | 10 Mar 2010 | 10 Mar 2010 | 2.50 Apples | 11 Mar 2010 | 16 Mar 2010 | 4.90 Apples | 17 Mar 2010 | 17 Mar 2010 | 2.50 Apples | 18 Mar 2010 | 23 Mar 2010 | 4.90 Apples | 24 Mar 2010 | 24 Mar 2010 | 2.50 Apples | 25 Mar 2010 | 30 Mar 2010 | 4.90 Apples | 31 Mar 2010 | 31 Mar 2010 | 2.50 What would please be the best approach to get this done? Thanks a lot in advance,

• Azure Table Storage data Consistency

  - by SeeR

  Let say I have Table in Azure Table Storage public class MyTable { public string PK {get; set;} public string RowPK {get; set;} public double Amount {get; set;} } And message in Azure Queue which says Add 10 to Amount. Now let say one worker role Takes this message from queue Takes row from table Amount += 10 Updates Row in Table And Fails After a while message is available in queue again. So next worker role: Takes this message from queue Takes row from table Amount += 10 Updates Row in Table Removes message from queue Those actions results in Amount += 20 instead of Amount += 10. How can I avoid such situations?

• Can't get NSTableView to display data.

  - by Alberto

  Hi! I see there are a lot of questions about this, but nothing helped me to get this work. I have a nib with a NSTableView with three columns (with the right identifiers set) and a class named ShortcutsTableController. In the nib I have a NSObject with class value ShortcutsTableController. I also connected the NSTableView to my controller as I usually do. This is header ShortcutsTableController.h. #import <Cocoa/Cocoa.h> @interface ShortcutsTableController : NSObject <NSTableViewDataSource> { IBOutlet NSTableView *shortcutsTable; NSMutableArray *shortcutsList; } - (int) numberOfRowsInTableView: (NSTableView*) tableView; - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row; @property (assign) IBOutlet NSTableView *shortcutsTable; - (void)setUpTable; @end And this is the implementation file ShortcutsTableController.m. #import "ShortcutsTableController.h" @implementation ShortcutsTableController @synthesize shortcutsTable; - (void)setUpTable { shortcutsList = [[NSMutableArray alloc] init]; NSDictionary *dict1 = [NSDictionary dictionaryWithObjectsAndKeys: @"blabla", @"nameColumn", @"Bla bla bla", @"shortcutColumn", @"Ribla", @"actionColumn", nil]; [shortcutsList addObject:dict1]; [shortcutsTable setDataSource:self]; [shortcutsTable reloadData]; } -(int) numberOfRowsInTableView: (NSTableView *) tableView { return [shortcutsList count]; } - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row { if (row != -1) return [[shortcutsList objectAtIndex:row] objectForKey:[tableColumn identifier]]; return nil; } @end But when i try to build nothing appears in the NSTableView. No errors, no warnings. Note that I call setUpTable from within the Delegate Class Method awakeFromNib. Is there something I am doing wrong? Thank you for you help. —Albé UPDATE. Added lines @property (assign) IBOutlet NSTableView *shortcutsTable; in header and @synthesize shortcutsTable; in implementation. Nothing changes. :(

• How to avoid circular relationship in SQL-Server?

  - by Shimmy

  I am creating a self-related table: Table Item columns: ItemId int - PK; Amount money - not null; Price money - a computed column using a UDF that retrieves value according to the items ancestors' Amount. ParentItemId int - nullable, reference to another ItemId in this table. I need to avoid a loop, meaning, a sibling cannot become an ancestor of his ancestors, meaning, if ItemId=2 ParentItemId = 1, then ItemId 1 ParentItemId = 2 shouldn't be allowed. I don't know what should be the best practice in this situation. I think I should add a CK that gets a Scalar value from a UDF or whatever else. EDIT: Another option is to create an INSTEAD OF trigger and put in 1 transaction the update of the ParentItemId field and selecting the Price field from the @@RowIdentity, if it fails cancel transaction, but I would prefer a UDF validating. Any ideas are sincerely welcomed.

• How to extend QueryableFilterRepeater to override the filters shown?

But now FilterRepeater is obsolete, and his successor QueryableFilterRepeater don't have such method. There is any way to override the columns used for filtering with QueryableFilterRepeater?

• Text mining with PHP

  - by garyc40

  Hi, I'm doing a project for a college class I'm taking. I'm using PHP to build a simple web app that classify tweets as "positive" (or happy) and "negative" (or sad) based on a set of dictionaries. The algorithm I'm thinking of right now is Naive Bayes classifier or decision tree. However, I can't find any PHP library that helps me do some serious language processing. Python has NLTK (http://www.nltk.org). Is there anything like that for PHP? I'm planning to use WEKA as the back end of the web app (by calling Weka in command line from within PHP), but it doesn't seem that efficient. Do you have any idea what I should use for this project? Or should I just switch to Python? Thanks

• Insert some data at later point once serialization(binary serialization) is done for a class

  - by coolcake

  My application is written in C# and I am a newbie to C#. I am facing with a problem during serialization. The problem is as follows. There are many classes in my project and when serialization is called on one of the main class object it serializes itself and during this process many of the member objects are also get serialized. This whole serialization is done in to a file with extension say ".bin". This bin file size should be of size max 20MB. In this process of serialization one of my other class also gets serialized to a stream, this class is having a big array. The size of this array or list can be of 80 MB or more. So during serialization i have serialize all the objects other than this array and depending upon the size left in the 20MB I need to add in between the serialization the number of array elements which can fit in the remaining memory. For the other array elements left out I have to create a similar kind of .bin file with all the objects serialized and in between need to insert the number of array elements that can fit there. The main problem here is the array elements get inserted at runtime and this list keeps on increasing. So i should be creating .bin files continuously until my application runs. Any ideas how can i implement a solution for this problem? Thanks in Advance.

• AJAX get data from large HTML page as the large HTML page loads

  - by Ed

  Not entirely sure whether this has a name but basically I have a large HTML page that is generated from results in a db. So viewing the HTML page (which is a report) in a browser directly does not display all contents immediately but displays what it has and additional HTML is added as the results from the DB are retrieved... Is there a way I can make an AJAX request to this HTML page and as opposed to waiting until the whole page (report) is ready, I can start processing the response as the HTML report is loaded? Or is there another way of doing it? Atm I make my AJAX response it just sits there for a minute or two until the HTML page is complete... If context is of any use: The HTML report is generated by a Java servlet and the page making the AJAX call is a JSP page. Unfortunately I can't very easily break the report up because it is generated by BIRT (Eclipse reporting extension). Thanks in advance.
