  • How to better design it ???

    - by Deepak
    public interface IBasePresenter { } public interface IJobViewPresenter : IBasePresenter { } public interface IActivityViewPresenter : IBasePresenter { } public class BaseView { public IBasePresenter Presenter { get; set; } } public class JobView : BaseView { public IJobViewPresenter JobViewPresenter { get { this.Presenter as IJobViewPresenter;} } } public class ActivityView : BaseView { public IActivityViewPresenter ActivityViewPresenter { get { this.Presenter as IActivityViewPresenter;} } } Lets assume that I need a IBasePresenter property on BaseView. Now this property is inherited by JobView and ActivityView but if I need reference to IJobViewPresenter object in these derived classes then I need to type cast IBasePresenter property to IJobViewPresenter or IActivityPresenter (which I want to avoid) or create JobViewPresenter and ActivityViewPresenter on derived classes (as shown above). I want to avoid type casting in derived classes and still have reference to IJobViewPresenter or IActivityViewPresenter and still have IBasePresenter in BaseView. Is there a way I can achieve it ?

  • Can't retrieve more than 2 gmail messages using Zend framework imap access - server dies - doens't r

    - by Ali
    Hi guys I'm working on a google apps application. Basically I've set it up so users can add multiple gmail addresses and check on their inboxes in the application. It works fine with a google apps email address however when I add a gmail address it just dies out. I'm using this code here: $mail = new Zend_Mail_Storage_Imap($mail_options); $all_messages = array(); $page = isset($_GET['page'])?$_GET['page']:1; $limit = isset($_GET['limit'])?$_GET['limit']:20; $offset = (($page-1)*$limit)+1; $end = ($page*$limit)>$c?$c:($page*$limit); for ($i=$offset;$i<=$end;$i++){ $h2t = new html2text(); $h2t->set_allowed_tags('<a>'); if(!$mail[$i]) break; else{ $one_message = $mail->getMessage($i); $one_message->id = $i; $one_message->UID = $mail->getUniqueId($i); $one_message->parts = array(); $one_message->body = ''; $count = 1; foreach (new RecursiveIteratorIterator($mail->getMessage($i)) as $ii=>$part) { try { $tpart = $part; //$tpart->_content = ''; $one_message->parts[$count] = $tpart; $count++; // check for html body if (strtok($part->contentType, ';') == 'text/html') { $b = $part->getContent(); if($part->contentTransferEncoding == 'quoted-printable') $b = quoted_printable_decode($b); $one_message->html_body = $b; $h2t->set_html($b); $one_message->body = $h2t->get_text(); } //check for text body if (strtok($part->contentType, ';') == 'text/plain') { $b = $part->getContent(); if($part->contentTransferEncoding == 'quoted-printable') $b = quoted_printable_decode($b); $one_message->text_body = $b; $one_message->body = $b;//$part->getContent(); } } catch (Zend_Mail_Exception $e) { // ignore } } $all_messages[] = $one_message; } } No matter what the emails it dies out on retrieving just 2 emails... whats going on here?

  • Why doesnt doesnt HTML input of type file not work with Ajax update panel

    - by Sean P
    I have a input of type file and when i try to do a Request.files when the input is wrapped in an update panel...it always returns an empty httpfilecollection. Why??? This is the codebehind: (At HttpContext.Current.Request.Files...its always 0 for the count.) Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Dim uploads As HttpFileCollection uploads = HttpContext.Current.Request.Files For i As Integer = 0 To (uploads.Count - 1) If (uploads(i).ContentLength > 0) Then Dim c As String = System.IO.Path.GetFileName(uploads(i).FileName) Try uploads(i).SaveAs("C:\UploadedUserFiles\" + c) Span1.InnerHtml = "File Uploaded Sucessfully." Catch Exp As Exception Span1.InnerHtml = "Some Error occured." End Try End If Next i End Sub This example comes from the ASP.Net website...but my application is very similar.

  • How to list all duplicated rows which may include NULL columns?

    - by Yousui
    Hi guys, I have a problem of listing duplicated rows that include NULL columns. Lemme show my problem first. USE [tempdb]; GO IF OBJECT_ID(N'dbo.t') IS NOT NULL BEGIN DROP TABLE dbo.t END GO CREATE TABLE dbo.t ( a NVARCHAR(8), b NVARCHAR(8) ); GO INSERT t VALUES ('a', 'b'); INSERT t VALUES ('a', 'b'); INSERT t VALUES ('a', 'b'); INSERT t VALUES ('c', 'd'); INSERT t VALUES ('c', 'd'); INSERT t VALUES ('c', 'd'); INSERT t VALUES ('c', 'd'); INSERT t VALUES ('e', NULL); INSERT t VALUES (NULL, NULL); INSERT t VALUES (NULL, NULL); INSERT t VALUES (NULL, NULL); INSERT t VALUES (NULL, NULL); GO Now I want to show all rows that have other rows duplicated with them, I use the following query. SELECT a, b FROM dbo.t GROUP BY a, b HAVING count(*) > 1 which will give us the result: a b -------- -------- NULL NULL a b c d Now if I want to list all rows that make contribution to duplication, I use this query: WITH duplicate (a, b) AS ( SELECT a, b FROM dbo.t GROUP BY a, b HAVING count(*) > 1 ) SELECT dbo.t.a, dbo.t.b FROM dbo.t INNER JOIN duplicate ON (dbo.t.a = duplicate.a AND dbo.t.b = duplicate.b) Which will give me the result: a b -------- -------- a b a b a b c d c d c d c d As you can see, all rows include NULLs are filtered. The reason I thought is that I use equal sign to test the condition(dbo.t.a = duplicate.a AND dbo.t.b = duplicate.b), and NULLs cannot be compared use equal sign. So, in order to include rows that include NULLs in it in the last result, I have change the aforementioned query to WITH duplicate (a, b) AS ( SELECT a, b FROM dbo.t GROUP BY a, b HAVING count(*) > 1 ) SELECT dbo.t.a, dbo.t.b FROM dbo.t INNER JOIN duplicate ON (dbo.t.a = duplicate.a AND dbo.t.b = duplicate.b) OR (dbo.t.a IS NULL AND duplicate.a IS NULL AND dbo.t.b = duplicate.b) OR (dbo.t.b IS NULL AND duplicate.b IS NULL AND dbo.t.a = duplicate.a) OR (dbo.t.a IS NULL AND duplicate.a IS NULL AND dbo.t.b IS NULL AND duplicate.b IS NULL) And this query will give me the answer as I wanted: a b -------- -------- NULL NULL NULL NULL NULL NULL NULL NULL a b a b a b c d c d c d c d Now my question is, as you can see, this query just include two columns, in order to include NULLs in the last result, you have to use many condition testing statements in the query. As the column number increasing, the condition testing statements you need in your query is increasing astonishingly. How can I solve this problem? Great thanks.

  • How can I write cocoa bindings as code instead of in the Interface Builder?

    - by johnjohndoe
    In my modell got an NSMutableArray that keeps track of a changing number of elements. In my view I got a NSTextField that shows the number of elements. The view gots unarchived from the nib file and alloc/inits the modell. Therefore it knowns about the modell and the contained array. I established the connection as follows. In the Interface Builder at the textfield I added a Cocoa Binding "path" like this: myModell.myArray.@count. By this I can access the count property (which is a must since the array itself does not change). The binding is based on key-value compliance which I established at the modell so the array can be accessed. But key-value compliance is not part of the questions. My question: How can I put the binding into the sourcecode and not writing it into the Interface Builder?

  • HTTP compression - can I configure a client to compress the data sent to a server?

    - by lgomide
    Hello, I'm using IIS 7 as web server for my application. If I enable dynamic content compression in the server, will this also enable clients to send compressed data to the server, if they can? I mean, my application uses SOAP webservices, and clients usually send large chunks of data to the server. The clients are written in C#/.NET. Is there any kind of configuration I can do in a web reference / serice reference in order to tell them to compress the content before they send it to IIS? And do I have to do any kind of configuration in IIS in order for this to work? Thanks in advance

  • Create a triangle out of stars using only recursion

    I need to to write a method that is called like printTriangle(5);. We need to create an iterative method and a recursive method (without ANY iteration).

  • How to define and work with an array of bits in C?

    - by Eddy
    I want to create a very large array on which I write '0's and '1's. I'm trying to simulate a physical process called random sequential adsorption, where units of length 2, dimers, are deposited onto an n-dimensional lattice at a random location, without overlapping each other. The process stops when there is no more room left on the lattice for depositing more dimers (lattice is jammed). Initially I start with a lattice of zeroes, and the dimers are represented by a pair of '1's. As each dimer is deposited, the site on the left of the dimer is blocked, due to the fact that the dimers cannot overlap. So I simulate this process by depositing a triple of '1's on the lattice. I need to repeat the entire simulation a large number of times and then work out the average coverage %. I've already done this using an array of chars for 1D and 2D lattices. At the moment I'm trying to make the code as efficient as possible, before working on the 3D problem and more complicated generalisations. This is basically what the code looks like in 1D, simplified: int main() { /* Define lattice */ array = (char*)malloc(N * sizeof(char)); total_c = 0; /* Carry out RSA multiple times */ for (i = 0; i < 1000; i++) rand_seq_ads(); /* Calculate average coverage efficiency at jamming */ printf("coverage efficiency = %lf", total_c/1000); return 0; } void rand_seq_ads() { /* Initialise array, initial conditions */ memset(a, 0, N * sizeof(char)); available_sites = N; count = 0; /* While the lattice still has enough room... */ while(available_sites != 0) { /* Generate random site location */ x = rand(); /* Deposit dimer (if site is available) */ if(array[x] == 0) { array[x] = 1; array[x+1] = 1; count += 1; available_sites += -2; } /* Mark site left of dimer as unavailable (if its empty) */ if(array[x-1] == 0) { array[x-1] = 1; available_sites += -1; } } /* Calculate coverage %, and add to total */ c = count/N total_c += c; } For the actual project I'm doing, it involves not just dimers but trimers, quadrimers, and all sorts of shapes and sizes (for 2D and 3D). I was hoping that I would be able to work with individual bits instead of bytes, but I've been reading around and as far as I can tell you can only change 1 byte at a time, so either I need to do some complicated indexing or there is a simpler way to do it? Thanks for your answers

  • How to make code run a certain amount of times before returning something?

    - by user3564967
    I made a trivia game and I have to make a method (SuccessOrFail) that will return whether the user beat the trivia or not. namespace D4 { /// <summary> /// Displays the trivia and returns whether the user succeeded or not, number of questions asked, and a free piece of trivia. /// </summary> public partial class TriviaForm : Form { private Trivia trivia; private Question question; private Random rand = new Random(); private HashSet<int> pickedQuestion = new HashSet<int>(); private string usersAnswer; private int numCorrectAnswers; private int numIncorrectAnswers; public TriviaForm() { InitializeComponent(); this.trivia = new Trivia(); QuestionRandomizer(); QuestionOutputter(); } /// <summary> /// This method will return true if succeeded or false if not. /// </summary> /// <returns>Whether the user got the trivia right or not</returns> public bool SuccessOrFail(bool wumpus) { bool successOrFail = false; int maxQuestions = 3; if (wumpus == true) maxQuestions = 5; int numNeededCorrect = maxQuestions / 2 + 1; if (this.usersAnswer == question.CorrectAnswer.ToString()) numCorrectAnswers++; else numIncorrectAnswers++; if (numCorrectAnswers + numIncorrectAnswers == maxQuestions) { if (numCorrectAnswers == numNeededCorrect) successOrFail = true; else successOrFail = false; numCorrectAnswers = 0; numIncorrectAnswers = 0; return successOrFail; } else return false; } /// <summary> /// This method will output a free answer to the player. /// </summary> public string FreeTrivia() { return question.Freetrivia; } // This method tells the player whether they were correct or not. private void CorrectOrNot() { if (this.usersAnswer == question.CorrectAnswer.ToString()) MessageBox.Show("Correct"); else MessageBox.Show("Incorrect"); } // Displays the questions and answers on the form. private void QuestionOutputter() { this.txtQuestion.Text = question.QuestionText; this.txtBox0.Text = question.Answers[0]; this.txtBox1.Text = question.Answers[1]; this.txtBox2.Text = question.Answers[2]; this.txtBox3.Text = question.Answers[3]; } // Clears the TextBoxes and displays a new random question. private void btnNext_Click(object sender, EventArgs e) { this.usersAnswer = txtAnswer.Text; CorrectOrNot(); this.txtQuestion.Clear(); this.txtBox0.Clear(); this.txtBox1.Clear(); this.txtBox2.Clear(); this.txtBox3.Clear(); this.txtAnswer.Clear(); this.txtAnswer.Focus(); QuestionRandomizer(); QuestionOutputter(); this.txtsuc.Text = SuccessOrFail(false).ToString(); } // Choose a random number and assign the corresponding data to question, refreshes the list if all questions used. private void QuestionRandomizer() { if (pickedQuestion.Count < trivia.AllQuestions.Count) { int random; do { random = rand.Next(trivia.AllQuestions.Count); } while (pickedQuestion.Contains(random)); pickedQuestion.Add(random); this.question = trivia.AllQuestions.ToArray()[random]; if (pickedQuestion.Count == trivia.AllQuestions.ToArray().Length) pickedQuestion.Clear(); } } } } My question is how to make it so that the code asks the user 3 or 5 questions and then returns whether the user won or not? I was wondering if somehow I could make a public void that would just make the form pop up and ask the user 3 to 5 questions and then once it asks the maximum number of questions, to close and then have a method that returns true if the user won, or false if they didn't. But I literally have no idea how to do that. Edit: So I know a for loop can make code run more than once. But the problem I'm having is, is that I don't know how to make it so that the trivia game asks 3 to 5 questions BEFORE returning something.

  • super() in Python 2.x without args

    - by Slava Vishnyakov
    Trying to convert super(B, self).method() into a simple nice bubble() call. Did it, see below! Is it possible to get reference to class B in this example? class A(object): pass class B(A): def test(self): test2() class C(B): pass import inspect def test2(): frame = inspect.currentframe().f_back cls = frame.[?something here?] # cls here should == B (class) c = C() c.test() Basically, C is child of B, B is child of A. Then we create c of type C. Then the call to c.test() actually calls B.test() (via inheritance), which calls to test2(). test2() can get the parent frame frame; code reference to method via frame.f_code; self via frame.f_locals['self']; but type(frame.f_locals['self']) is C (of course), but not B, where method is defined. Any way to get B?

  • Why are all response bodies after the first blank in Cucumber?

    - by James A. Rosen
    I'm using Cucumber (0.6.3), Cucumber-Rails (0.3.0), Webrat (0.7.0), and Rails (2.3.5) for some tests. The following scenario passes just fine: Scenario: load one page Given I am on the home page Then I should see "Welcome" The following, however, fails: Scenario: load two pages Given I am on the FAQ pag When I go to the home page Then I should see "Welcome" The problem is that the second @response.body is blank. I added a Rack middleware to get a little more information: class LogEachRequest def initialize(app); @app = app; @count = 0; end def call(env) puts "Processing request # #{@count += 1)" @app.call(env) end end It shows me only one request processed. That is, it only ever prints out Processing request # 1

  • Losing NSManaged Objects in my Application

    - by Wayfarer
    I've been doing quite a bit of work on a fun little iPhone app. At one point, I get a bunch of player objects from my Persistant store, and then display them on the screen. I also have the options of adding new player objects (their just custom UIButtons) and removing selected players. However, I believe I'm running into some memory management issues, in that somehow the app is not saving which "players" are being displayed. Example: I have 4 players shown, I select them all and then delete them all. They all disappear. But if I exit and then reopen the application, they all are there again. As though they had never left. So somewhere in my code, they are not "really" getting removed. MagicApp201AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; context = [appDelegate managedObjectContext]; NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *desc = [NSEntityDescription entityForName:@"Player" inManagedObjectContext:context]; [request setEntity:desc]; NSError *error; NSMutableArray *objects = [[[context executeFetchRequest:request error:&error] mutableCopy] autorelease]; if (objects == nil) { NSLog(@"Shit man, there was an error taking out the single player object when the view did load. ", error); } int j = 0; while (j < [objects count]) { if ([[[objects objectAtIndex:j] valueForKey:@"currentMultiPlayer"] boolValue] == NO) { [objects removeObjectAtIndex:j]; j--; } else { j++; } } [self setPlayers:objects]; //This is a must, it NEEDS to work Objects are all the players playing So in this snippit (in the viewdidLoad method), I grab the players out of the persistant store, and then remove the objects I don't want (those whose boolValue is NO), and the rest are kept. This works, I'm pretty sure. I think the issue is where I remove the players. Here is that code: NSLog(@"Remove players"); /** For each selected player: Unselect them (remove them from SelectedPlayers) Remove the button from the view Remove the button object from the array Remove the player from Players */ NSLog(@"Debugging Removal: %d", [selectedPlayers count]); for (int i=0; i < [selectedPlayers count]; i++) { NSManagedObject *rPlayer = [selectedPlayers objectAtIndex:i]; [rPlayer setValue:[NSNumber numberWithBool:NO] forKey:@"currentMultiPlayer"]; int index = [players indexOfObjectIdenticalTo:rPlayer]; //this is the index we need for (int j = (index + 1); j < [players count]; j++) { UIButton *tempButton = [playerButtons objectAtIndex:j]; tempButton.tag--; } NSError *error; if ([context hasChanges] && ![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } UIButton *aButton = [playerButtons objectAtIndex:index]; [players removeObjectAtIndex:index]; [aButton removeFromSuperview]; [playerButtons removeObjectAtIndex:index]; } [selectedPlayers removeAllObjects]; NSError *error; if ([context hasChanges] && ![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } NSLog(@"About to refresh YES"); [self refreshAllPlayers:YES]; The big part in the second code snippet is I set them to NO for currentMultiPlayer. NO NO NO NO NO, they should NOT come back when the view does load, NEVER ever ever. Not until I say so. No other relevant part of the code sets that to YES. Which makes me think... perhaps they aren't being saved. Perhaps that doesn't save, perhaps those objects aren't being managed anymore, and so they don't get saved in. Is there a lifetime (metaphorically) of NSManaged object? The Players array is the same I set in the "viewDidLoad" method, and SelectedPlayers holds players that are selected, references to NSManagedObjects. Does it have something to do with Removing them from the array? I'm so confused, some insight would be greatly appreciated!!

  • Creating a VS 2010 Project with only content files.

    - by Cameron Peters
    I have some content files that I would like to share between a number of projects in Visual Studio. I have put these files in their own project, set the build action to "Content", and the copy to output directory to "Copy if newer". I would like all these files to be copied to the bin/debug directory of the projects that reference them. I can get it to work by including a reference to the "contents" project in each of the projects that need the files, but that requires that a minimal assembly be generated (3K). I assume there is a way, using MSBuild, to make this all work without creating the empty assembly?

  • When using a HiLo ID generation strategy, what types should be used to hold Ids?

    - by UpTheCreek
    I'm asking this from a c#/NHibnernate perspective, but it's generally applicable. The concern is that the HiLo strategy goes though id's pretty quickly, and for example a low record-count table (Such as Users) is sharing from the same set of id's as a high record-count table (Such as comments). So you can potentially get to high numbers quicker that with other strategies. So what do people recommend? Code side: int/uint/long/ulong? DBSide: int/bigint? My feeling is to go with longs and bigingts, but would like a sanity check :)

  • What's your favourite programming language, and its killer feature?

    - by eplawless
    Each language I've used has had its pros and cons, but some features have really shone through as being indispensible, shining examples of how to design a programming language to make programmers happy. I use PHP a lot at work, and the one thing I really miss when moving to other languages is PHP's foreach: foreach($items as $item) //iterate through items by value foreach($items as &$item) //iterate through items by reference foreach($items as $i => $item) //by value, with indices foreach($items as $i => &$item) //by reference, with indices In C#, I'm kind of smitten with the built-in multicast delegate system, as well as the way it handles getters and setters. So what's your favourite/favorite language, and what feature makes it awesome?

  • Shared static classes between AppDomains in loaded library code

    - by Christian Stewart
    I'm working on a program in which I want to do something similar to what the Photon Server system does: Offer a common "API" class library, which contains common data classes, enumerations, and interfaces for working with the host program. Have client programs (class libraries) reference this DLL and implement interfaces listed within it. Have the "host" application load built DLL client libraries into separate AppDomains and reference the interfaces that lie within to have polymorphic client code from within a dll file. I have something like this worked out: a class library that contains common code, but I've run into the following question How should I handle static classes? Should I add a method that is called by the host program to synchronize data? How do I keep a static class the same between AppDomains? Should I discard these classes in favor of better interfaces between the code levels? And in general, how do I share data between these loaded AppDomains?

  • How to Track Number of Changes Occured in a Column? T-SQL - SQL Server

    - by user327387
    For example, i have a column named EmployeeName. Every time a user changes/fix his name, i need to keep a count. If he changes his name twice, then count is 2. Also, i need to store the time of every change employee makes on EmployeeName e.g. if the name essentially is James and time created is 9:00 AM and then employee changes to John on 11:00 AM, i need to preserve this new time and new value as well as the previous one which is James at 9:00 AM. I hope its clear! Thank you guys...Best Answer will be chosen... If this requires a trigger, giving a sketchy pseudo-code will be very much appreciated.

  • How can I dispose of an object (say a Bitmap) when it becomes orphaned ?

    - by Jelly Amma
    I have a class A providing Bitmaps to other classes B, C, etc. Now class A holds its bitmaps in a ring queue so after a while it will lose reference to the bitmap. While it's still in the queue, the same Bitmap can be checked out by several classes so that, say, B and C can both hold a reference to this same Bitmap. But it can also happen that only one of them checked out the Bitmap or even none of them. I would like to dispose of the bitmap when it's not being needed any more by either A, B or C. I suppose I have to make B and C responsible for somehow signaling when they're finished using it but I'm not sure about the overall logic. Should it be a call to something like DisposeIfNowOrphan() that would be called : 1 - when the Bitmap gets kicked out of the queue in class A 2 - when B is finished with it 3 - when C is finished with it If that's the best strategy, how can I evaluate the orphan state ? Any advice would be most welcome.

  • problems with extended classes and overwrite with methods

    - by Marco
    I have a .net website written in C# and will make functionalities that other developers can use. So i will make some default implementation and a developer can overwrite some methods Example: i have a class ShoppingCart and a class Product the class product haves a method getProductPrice the shoppingcart will call the method getProductPrice for calculating the total price of cart The Shoppingcart and Product are in the same project and i will give the developers the .dll so they can't change the source code so we can update the assembly later So they need to make a other project and extend the product class and overwrite the method getProductPrice so they can implement there own logic The problem is that the shoppingcart will not call the extended method but the original If we make already a extended project for the developers and the shoppingcart will call the extended method then we have a circular reference because the extended product needs a reference to product and the shopping cart to the extended product partial classes also don't works because we only can use partials within the same assembly anyone a suggestion ? thanks in advance

  • How can I use linq to build an object from 1 row of data?

    - by Hcabnettek
    Hi All, I have a quick linq question. I have a stored proc that should return one row of data. I would like to use a lambda to build an object. Here's what I'm currently doing which works, but I know I should be able to use First instead of Select except I can't seem to get the syntax correct. Can anyone straighten me out here? Thanks for any help. var location = new GeoLocationDC(); DataSet ds = db.ExecuteDataSet(dbCommand); if(ds.Tables[0].Rows.Count == 1) { var rows = ds.Tables[0].AsEnumerable(); var x = rows.Select( c => new GeoLocationDC { Latitude = Convert.ToInt32(c.Field<string>("LATITUDE")), Longitude = Convert.ToInt32(c.Field<string>("LONGITUDE")) }).ToList(); if(x.Count > 0 ) { location = x[0]; } Cheers, ~ck }

  • How can I check the content of the arrays? Parsing XML file with ObjectiveC

    - by skiria
    I have 3 classes- video { nameVideo, id, description, user... } topic {nameTopic, topicID, NSMutableArray videos; } category {nameCategory, categoryID, NSMUtableArray topics} And then in my app delegate I defined- NSMutableArray categories; I parse an XML file with this code. I try the arrays hierachy, and i think that i don't add any object on the arrays. How can I check it? What's wrong? (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { if([elementName isEqualToString:@"Videos"]) { //Initialize the array. appDelegate.categories = [[NSMutableArray alloc] init]; } else if ([elementName isEqualToString:@"Category"]) { aCategory = [[Category alloc] init]; aCategory.categoryID = [[attributeDict objectForKey:@"id"] integerValue]; NSLog(@"Reading id category value: %i", aCategory.categoryID); } else if ([elementName isEqualToString:@"Topic"]) { aTopic = [[Topic alloc] init]; aTopic.topicID = [[attributeDict objectForKey:@"id"] integerValue]; NSLog(@"Reading id topic value: %i", aTopic.topicID); } else if ([elementName isEqualToString:@"video"]) { aVideo = [[Video alloc] init]; aVideo.videoID = [[attributeDict objectForKey:@"id"] integerValue]; aVideo.nameTopic = currentNameTopic; aVideo.nameCategory = currentNameCategory; NSLog(@"Reading id video value: %i", aVideo.videoID); } NSLog(@"Processing Element: %@", elementName); } (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(!currentElementValue) currentElementValue = [[NSMutableString alloc] initWithString:string]; else [currentElementValue appendString:string]; NSLog(@"Processing Value: %@", currentElementValue); } (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if([elementName isEqualToString:@"Videos"]) return; if ([elementName isEqualToString:@"Category"]) { [appDelegate.categories addObject:aCategory]; [aCategory release]; aCategory = nil; } if ([elementName isEqualToString:@"Topic"]) { [aCategory.topics addObject:aTopic]; //NSLog(@"contador: %i", [aCategory.topics count]); //NSLog(@"contador: %@", aTopic.nameTopic); [aTopic release]; aTopic = nil; } if ([elementName isEqualToString:@"video"]) { [aTopic.videos addObject:aVideo]; NSLog(@"count number videos: %i", [aTopic.videos count]); -- always 0 NSLog(@"NOM CATEGORIA VIDEO: %@", aVideo.urlVideo); -- OK [aVideo release]; aVideo = nil; } if ([elementName isEqualToString:@"nameCategory"]) { //[aCategory setValue:currentElementValue forKey:elementName]; aCategory.nameCategory = currentElementValue; currentNameCategory = currentElementValue; } if ([elementName isEqualToString:@"nameTopic"]) { aTopic.nameTopic = currentElementValue; currentNameTopic = currentElementValue; } else [aVideo setValue:currentElementValue forKey:elementName]; [currentElementValue release]; currentElementValue = nil; }

  • How to use a data type (table) defined in another database in SQL2k8?

    - by Victor Rodrigues
    I have a Table Type defined in a database. It is used as a table-valued parameter in a stored procedure. I would like to call this procedure from another database, and in order to pass the parameter, I need to reference this defined type. But when I do DECLARE @table dbOtherDatabase.dbo.TypeName , it tells me that The type name 'dbOtherDatabase.dbo.TypeName' contains more than the maximum number of prefixes. The maximum is 1. How could I reference this table type?
