  • Execute files included in Resource folder

    - by Sumeet Pujari
    In WPF application where I have included some files in resources, I want to execute them on a button click. How do I specify a path in Process.Start(). private void button1_Click_2(object sender, RoutedEventArgs e) { Process.Start("test.txt"); } Or is there any other way? private void button1_Click_2(object sender, RoutedEventArgs e) { string path = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + @"\test.txt"; if (File.Exists(path)) { Process.Start(new ProcessStartInfo(path)); } else { MessageBox.Show("No file found"+path); } I added a message box and it showed No files found. :( EDIT: I Tried to check the path after publishing and this what i got. No File Found With a Path - C:\Users\Administrator\AppData\Local\Apps\2.0... test.txt Before I published the Application I got a path which id No File Found at ..project..\bin\Debug\test.txt which is obvious since my Resource file not included there its Under a Resource Folder and not Debug when i add a test file in debug it open without any problem. Can someone Help throwing some light on this case. EDIT: I want to open a file from Resource directory @ C:\Users\Administrator\Documents\Visual Studio 2010\Projects\FastFix\FastFix\Resources Which would be included in my project when i am going to publish it is going to run as a standalone application without installation.

  • What happens when you create an instance of an object containing no state in C#?

    - by liquorice
    I am I think ok at algorithmic programming, if that is the right term? I used to play with turbo pascal and 8086 assembly language back in the 1980s as a hobby. But only very small projects and I haven't really done any programming in the 20ish years since then. So I am struggling for understanding like a drowning swimmer. So maybe this is a very niave question or I'm just making no sense at all, but say I have an object kind of like this: class Something : IDoer { void Do(ISomethingElse x) { x.DoWhatEverYouWant(42); } } And then I do var Thing1 = new Something(); var Thing2 = new Something(); Thing1.Do(blah); Thing2.Do(blah); does Thing1 = Thing2? does "new Something()" create anything? Or is it not much different different from having a static class, except I can pass it around and swap it out etc. Is the "Do" procedure in the same location in memory for both the Thing1(blah) and Thing2(blah) objects? I mean when executing it, does it mean there are two Something.Do procedures or just one?

  • onKeypress Enter Key event on textfield not working in Chrome

    - by rlcrews
    I have a question along the same vein as the one asked here regarding how the enter key is handled in chrome. The effect I am trying to accomplish is to allow the enter key to call a click event of one a button while focus in within the current field. To accomplish this I am using the following code: javascript: <script type="text/javascript"> //attempting to capture keypress for chrome here but this is not working $("#txtContainer").keypress(function (e) { if (e.keyCode == '13') { e.preventDefault(); doClick(buttonname, e); return false; } }); function doClick(buttonName, e) { var key; if (window.event) key = window.event.keyCode; //IE else key = e.which; //firefox if (key == 13) { var btn = document.getElementById(buttonName); if (btn != null) { btn.click(); event.keyCode = 0 } } } </script> within the aspx <form id="form1" runat="server"> <div> <asp:LinkButton ID="newBtn" runat="server" OnClick="btnLogin_Click" Text="ASP Link" /> <asp:TextBox ID="txtContainer" runat="server" Width="100" /> <asp:Label ID="time_lbl" runat="server" /> </div> </form> and within the code behind aspx.cs protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { txtContainer.Attributes.Add("onKeyPress", "doClick('" + newBtn.ClientID + "',event)"); } } public void btnLogin_Click(object sender, EventArgs e) { time_lbl.Text = txtContainer.Text; } The above code works fine in FF and IE however chrome continues to submit the entire form vs. capturing the keypress on the enterkey. Thank you for any suggestions.

  • when i set property(retain), one "self" = one "retain"?

    - by Walter
    although I'm about to finish my first app, I'm still confused about the very basic memory management..I've read through many posts here and apple document, but I'm still puzzled.. For example..I'm currently doing things like this to add a label programmatically: @property (retain, nonatomic) UILabel *showTime; @sythesize showTime; showTime = [[UILabel alloc] initWithFrame:CGRectMake(45, 4, 200, 36)]; [self.showTime setText:[NSString stringWithFormat:@"%d", time]]; [self.showTime setFont:[UIFont fontWithName:@"HelveticaRoundedLT-Bold" size:23]]; [self.showTime setTextColor:numColor]; self.showTime.backgroundColor = [UIColor clearColor]; [self addSubview:self.showTime]; [showTime release]; this is my current practice, for UILabel, UIButton, UIImageView, etc... [Alloc init] it without self., coz I know this will retain twice.. but after the allocation, I put back the "self." to set the attributes.. My gut feel tells me I am doing wrong, but it works superficially and I found no memory leak in analyze and instruments.. can anyone give my advice? when I use "self." to set text and set background color, does it retain one automatically? THX so much!

  • Plugin-like architecture in .NET

    - by devoured elysium
    I'm trying to implement a plug-in like application. I know there are already several solution out there but this is just going to be proof of the concept, nothing more. The idea would be to make the application main application almost featureless by default and then let the plugins know about each other, having them have implement all the needed features. A couple of issues arise: I want the plugins at runtime to know about each other through my application. That wouldn't mean that at code-time they couldn't reference other plugin's assemblies so they could use its interfaces, only that plugin-feature initialization should be always through my main app. For example: if I have both plugins X and Y loaded and Y wants to use X's features, it should "register" its interest though my application to use its features. I'd have to have a kind of "dictionary" in my application where I store all the loaded plugins. After registering for interest in my application, plugin Y would get a reference to X so it could use it. Is this a good approach? When coding plugin Y that uses X, I'd need to reference X's assembly, so I can program against its interface. That has the issue of versioning. What if I code my plugin Y against an outdated version of plugin X? Should I always use a "central" place where all assemblies are, having there always the up to date versions of the assemblies? Are there by chance any books out there that specifically deal with these kinds of designs for .NET? Thanks

  • Generic Singleton Fasade design pattern

    - by Paul
    Hi I try write singleton fasede pattern with generics. I have one problem, how can I call method from generic variable. Something like this: T1 t1 = new T1(); //call method from t1 t1.Method(); In method SingletonFasadeMethod I have compile error: Error 1 'T1' does not contain a definition for 'Method' and no extension method 'Method' accepting a first argument of type 'T1' could be found (are you missing a using directive or an assembly reference?) Any advace? Thank, I am beginner in C#. All code is here: namespace GenericSingletonFasade { public interface IMyInterface { string Method(); } internal class ClassA : IMyInterface { public string Method() { return " Calling MethodA "; } } internal class ClassB : IMyInterface { public string Method() { return " Calling MethodB "; } } internal class ClassC : IMyInterface { public string Method() { return "Calling MethodC"; } } internal class ClassD : IMyInterface { public string Method() { return "Calling MethodD"; } } public class SingletonFasade<T1,T2,T3> where T1 : class,new() where T2 : class,new() where T3 : class,new() { private static T1 t1; private static T2 t2; private static T3 t3; private SingletonFasade() { t1 = new T1(); t2 = new T2(); t3 = new T3(); } class SingletonCreator { static SingletonCreator() { } internal static readonly SingletonFasade<T1,T2,T3> uniqueInstace = new SingletonFasade<T1,T2,T3>(); } public static SingletonFasade<T1,T2,T3> UniqueInstace { get { return SingletonCreator.uniqueInstace; } } public string SingletonFasadeMethod() { //Problem is here return t1.Method() + t2.Method() + t3.Method(); } } }

  • NHibernate not dropping foreign key constraints.

    - by Kendrick
    I'm new to NHibernate, so this is probably my mistake, but when I use: schema.Create(true, true); I get: SchemaExport [(null)]- There is already an object named 'XXX' in the database. System.Data.SqlClient.SqlException: There is already an object named 'XXX' in the database. I grabbed the SQL code nHibernate was using, ran it directly from MSSMS, and recieved similar errors. Looking into it, the generated code is not properly dropping the foreign key constraints. The drop looks like this: if exists (select 1 from sysobjects where id = OBJECT_ID(N'dbo[FK22212EAFBFE4C58]') AND parent_obj = OBJECT_ID('YYY')) alter table dbo.YYY drop constraint FK22212EAFBFE4C58 Doing a "select OBJECT_ID(N'dbo[FK22212EAFBFE4C58]')" I get null. If I take out the "dbo" (i.e. "select OBJECT_ID(N'[FK22212EAFBFE4C58]')") then the ID is returned. So, my question is, why is nHibernate adding the dbo, and why does that prevent the object from being returned (since the table owning the constraint is dbo.XXX) One of my mapping files: <?xml version="1.0" encoding="utf-8"?> <hibernate-mapping namespace="CanineApp.Model" assembly="CanineApp.Model" xmlns="urn:nhibernate-mapping-2.2"> <class name="MedicalLog" table="MedicalLog" schema="dbo"> <id name="MedicalLogID" type="Int64"> <generator class="identity" /> </id> <property name="InvoiceAmount" type="Decimal" not-null="true" /> ... <many-to-one name="Canine" class="Canine" column="CanineID" not-null="true" fetch="join" /> <many-to-one name="TreatmentCategory" class="TreatmentCategory" column="TreatmentCategoryID" not-null="true" access="field.camelcase-underscore" /> </class> </hibernate-mapping>

  • How to override jquery's show() and hide() functions

    - by Max Williams
    hi all Short version of question: see title Long version of question: I've used jquery's show() and hide() functions extensively in my code and just encountered a bit of a problem: they work by changing the display attribute of the element to 'block' or 'none' respectively, so that if you have somethin that has display: inline and then hide and show it, you've changed its display to block, which screws up the layout in a couple of cases. In my code, whenever i want something to be hidden initially i give it a class 'hidden'. This class is simply {display: none}. I'd like the change show and hide to remove or add this class, instead of directly changing the display attribute, so that if you add the hidden class and then remove it again (ie hide and show something) then it's back to exactly how it was to start off with (since adding a class overrides the attributes rather than directly changing them). Something like this (this is a little pseucodey as i don't know how to set the function up properly - let's assume that 'this' is the object that show/hide was called on) function show(){ this.removeClass("hidden"); } function hide(){ this.addClass("hidden"); } how and where would i go about overriding the jquery methods? (I'm not a javascript expert) thanks - max

  • Multiple Foreign keys to a single table and single key pointing to more than one table

    - by user1216775
    I need some suggestions from the database design experts here. I have around six foreign keys into a single table (defect) which all point to primary key in user table. It is like: defect (.....,assigned_to,created_by,updated_by,closed_by...) If I want to get information about the defect I can make six joins. Do we have any better way to do it? Another one is I have a states table which can store one of the user-defined set of values. I have defect table and task table and I want both of these tables to share the common state table (New, In Progress etc.). So I created: task (.....,state_id,type_id,.....) defect(.....,state_id,type_id,...) state(state_id,state_name,...) importance(imp_id,imp_name,...) There are many such common attributes along with state like importance(normal, urgent etc), priority etc. And for all of them I want to use same table. I am keeping one flag in each of the tables to differentiate task and defect. What is the best solution in such a case? If somebody is using this application in health domain, they would like to assign different types, states, importances for their defect or tasks. Moreover when a user selects any project I want to display all the types,states etc under configuration parameters section.

  • Disable Products in different Magento Store Views

    - by Robert
    I have a Magento Multi-Store installation (not multi-site) and some products are available in more than one store. However, these products that are available in, let's say storeA and storeB, have related products, BUT, the related products are not available in both stores. The problem is this, Product1, which has Product2, Product3, and Product4 as related products, appears in storeA. No Problem. Product1 is also available in storeB, but NOT Product2-3-4. However, those products, though not shown in the general catalog of storeB, are visible as related products to Product1 in storeB. If I use the drop down to manage products in storeB, and I remove the related products in Product1, it removes the related products from Product1 in storeA, where they should be available. I cannot change the status attribute to storeview in Manage Attributes, because the only choices are Global or Website, not Store View. I can change the skin to show UPSELL products instead, and set up different UPSELL products, but that limits my stores to only two. Any ideas?

  • safe structures embedded systems

    - by user405633
    I have a packet from a server which is parsed in an embedded system. I need to parse it in a very efficient way, avoiding memory issues, like overlapping, corrupting my memory and others variables. The packet has this structure "String A:String B:String C". As example, here the packet received is compounded of three parts separated using a separator ":", all these parts must be accesibles from an structure. Which is the most efficient and safe way to do this. A.- Creating an structure with attributes (partA, PartB PartC) sized with a criteria based on avoid exceed this sized from the source of the packet, and attaching also an index with the length of each part in a way to avoid extracting garbage, this part length indicator could be less or equal to 300 (ie: part B). typedef struct parsedPacket_struct { char partA[2];int len_partA; char partB[300];int len_partB; char partC[2];int len_partC; }parsedPacket; The problem here is that I am wasting memory, because each structure should copy the packet content to each the structure, is there a way to only save the base address of each part and still using the len_partX.

  • RegExpValidator never matches

    - by babyangel86
    Hi, I've got a class that's meant to validate input fields to make sure the value is always a decimal. I've tested the regex here: http://livedocs.adobe.com/flex/3/html/help.html?content=validators_7.html, and it looks like it does the right thing, but in my app, I can't seem to get it to match to a number format. Class Definition: public class DecimalValidator { //------------------------------- ATTRIBUTES public var isDecimalValidator:RegExpValidator; //------------------------------- CONSTRUCTORS public function DecimalValidator() { isDecimalValidator = new RegExpValidator(); isDecimalValidator.expression = "^-?(\d+\.\d*|\.\d+)$"; isDecimalValidator.flags = "g"; isDecimalValidator.required = true; isDecimalValidator.property = "text"; isDecimalValidator.triggerEvent = FocusEvent.FOCUS_OUT; isDecimalValidator.noMatchError = "Float Expected"; } } Setting the source here: public function registerDecimalInputValidator(inputBox:TextInput, valArr:Array):void { // Add Validators var dValidator:DecimalValidator = new DecimalValidator(); dValidator.isDecimalValidator.source = inputBox; dValidator.isDecimalValidator.trigger = inputBox; inputBox.restrict = "[0-9].\\.\\-"; inputBox.maxChars = 10; valArr.push(dValidator.isDecimalValidator); } And Calling it here: registerDecimalInputValidator(textInput, validatorArr); Where textInput is an input box created earlier. Clearly I'm missing something simple yet important, but I'm not entirely sure what! Any help would be much appreciated.

  • SQL query select from table and group on other column...

    - by scaryjones
    I'm phrasing the question title poorly as I'm not sure what to call what I'm trying to do but it really should be simple. I've a link / join table with two ID columns. I want to run a check before saving new rows to the table. The user can save attributes through a webpage but I need to check that the same combination doesn't exist before saving it. With one record it's easy as obviously you just check if that attributeId is already in the table, if it is don't allow them to save it again. However, if the user chooses a combination of that attribute and another one then they should be allowed to save it. Here's an image of what I mean: So if a user now tried to save an attribute with ID of 1 it will stop them, but I need it to also stop them if they tried ID's of 1, 10 so long as both 1 and 10 had the same productAttributeId. I'm confusing this in my explanation but I'm hoping the image will clarify what I need to do. This should be simple so I presume I'm missing something.

  • Comparing lists of field-hashes with equivalent AR-objects.

    - by Tim Snowhite
    I have a list of hashes, as such: incoming_links = [ {:title => 'blah1', :url => "http://blah.com/post/1"}, {:title => 'blah2', :url => "http://blah.com/post/2"}, {:title => 'blah3', :url => "http://blah.com/post/3"}] And an ActiveRecord model which has fields in the database with some matching rows, say: Link.all => [<Link#2 @title='blah2' @url='...post/2'>, <Link#3 @title='blah3' @url='...post/3'>, <Link#4 @title='blah4' @url='...post/4'>] I'd like to do set operations on Link.all with incoming_links so that I can figure out that <Link#4 ...> is not in the set of incoming_links, and {:title => 'blah1', :url =>'http://blah.com/post/1'} is not in the Link.all set, like so: #pseudocode #incoming_links = as above links = Link.all expired_links = links - incoming_links missing_links = incoming_links - links expired_links.destroy missing_links.each{|link| Link.create(link)} One route I've tried: I'd rather not rewrite Array#- and such, and I'm okay with converting incoming_links to a set of unsaved Link objects; so I've tried overwriting hash eql? and so on in Link so that it ignored the id equality that AR::Base provides by default. But this is the only place this sort of equality should be considered in the application - in other places the Link#id default identity is required. Is there some way I could subclass Link and apply the hash, eql?, etc overwriting there? The other route I've tried is to pull out the attributes hash for each Link and doing a .slice('id',...etc) to prune the hashes down. But this requires writing seperate methods for keeping track of the Link objects while doing set operations on the hashes, or writing seperate Collection classes to wrap the incoming_links hash-list and Link-list which seems a bit overkill. What is the best way to design this interaction? Extra credit for cleanliness.

  • getting active records to display as a plist

    - by phil swenson
    I'm trying to get a list of active record results to display as a plist for being consumed by the iphone. I'm using the plist gem v 3.0. My model is called Post. And I want Post.all (or any array or Posts) to display correctly as a Plist. I have it working fine for one Post instance: [http://pastie.org/580902][1] that is correct, what I would expect. To get that behavior I had to do this: class Post < ActiveRecord::Base def to_plist attributes.to_plist end end However, when I do a Post.all, I can't get it to display what I want. Here is what happens: http://pastie.org/580909 I get marshalling. I want output more like this: [http://pastie.org/580914][2] I suppose I could just iterate the result set and append the plist strings. But seems ugly, I'm sure there is a more elegant way to do this. I am rusty on Ruby right now, so the elegant way isn't obvious to me. Seems like I should be able to override ActiveRecord and make result-sets that pull back more than one record take the ActiveRecord::Base to_plist and make another to_plist implementation. In rails, this would go in environment.rb, right?

  • Does RazorEngine require MVC3 to be installed?

    - by tkha007
    I am working on a web project that uses MVC2. I decided to try out RazorEngine to do some e-mail templating. This appeared to work fine when I was protyping using an MVC2 project so I assumed that RazorEngine will work fine for my e-mail templating solution. What I had forgotten at the time was that I actually had MVC3 installed on my local development machine. After deploying the project on a pre-test server I get the following error in the logs when the application attempts to do anything with RazorEngine: Could not load file or assembly 'System.Web.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. File name: 'System.Web.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' at RazorEngine.Compilation.DefaultCompilerServiceFactory.CreateCompilerService(Language language) at RazorEngine.Templating.TemplateService.CreateTemplateType(String razorTemplate, Type modelType) at RazorEngine.Templating.TemplateService.CreateTemplate[T](String razorTemplate, T model) at RazorEngine.Templating.TemplateService.Parse[T](String razorTemplate, T model) at RazorEngine.Razor.Parse[T](String razorTemplate, T model) at System.Dynamic.UpdateDelegates.UpdateAndExecute3[T0,T1,T2,TRet](CallSite site, T0 arg0, T1 arg1, T2 arg2) at Persistence.Utility.RazorEngineHelper.Parse(String templateName, Object model) in The fact that it can't find 'System.Web.Razor' means that this DLL does not exist on the deployed server. The only difference I can think of between the deployment server and my local dev machine is that the deployment server does not have MVC3 installed but I may be mistaken because the deployment server is not something I normally control and as such I don't have a lot of information about it. It is meant to host this particular application so there have been previous deployments of this application to this server. This is the first time I'm making a deployment with RazorEngine as a dependency.

  • Best way to do client/server validation in ASP.NET in 2010?

    - by punkouter
    First there was the ASP.NET validators and we used them... Then some people on the team did things manually in javascript... Then a bunch of jquery validation libraries came out... Then MVC2 came out with attributes as validators.. I work with apps that have alot of forms with alot of various validation (Some fields needs to be compared with other values in a DB so a postball/ajax call is required) .. Right now I have a mess of ASP.NET custom validators and functions that calculate on the server side as well. Can I get some opinions on the best tool/combination to approach this job that can create the smallest/most elegant code? Pure server side solution? AJAX/Jquery? A certain plugin for jquery? For example, I have 2 dates.. I want to make sure that the 1st date is less than the 2nd date... Are there jquery validators that encapsulate this? My feeling is if I can get jquery plugins to handle half the more basic validation for my that could cut my code in half.

  • Is there a way to identify that a file has been modified and moved?

    - by Eric
    I'm writing an application that catalogs files, and attributes them with extra meta data through separate "side-car" files. If changes to the files are made through my program then it is able to keep everything in sync between them and their corresponding meta data files. However, I'm trying to figure out a way to deal with someone modifying the files manually while my program is not running. When my program starts up it scans the file system and compares the files it finds to it's previous record of what files it remembers being there. It's fairly straight forward to update after a file has been deleted or added. However, if a file was moved or renamed then my program sees that as the old file being deleted, and the new file being added. Yet I don't want to loose the association between the file and its metadata. I was thinking I could store a hash from each file so I could check to see if newly found files were really previously known files that had been moved or renamed. However, if the file is both moved/renamed and modified then the hash would not match either. So is there some other unique identifier of a file that I can track which stays with it even after it is renamed, moved, or modified?

    This has me pooped, is there any reason the following: public abstract class aExtension { public abstract bool LoadExtension(Constants c); // method required in inherit public abstract string AppliesToModule // property required in inherit { get; } public abstract string ExtensionName // property required in inherit { get; } public abstract string ExtensionDescription // property required in inherit { get; } } public class UK : aExtension { public override bool LoadExtension(Constants c) { return true; } public override string AppliesToModule { get { return "string"; } } public override string ExtensionName { get { return "string"; } } public override string ExtensionDescription { get { return "string"; } } } would return false for the following expressions: bool a = t.IsAssignableFrom(aExtension)); bool b = t.BaseType.IsAssignableFrom(aExtension)); bool c = typeof(aExtension).IsAssignableFrom(t); bool d = typeof(aExtension).IsAssignableFrom(t.BaseType); bool e = typeof(aExtension).IsSubclassOf(t); bool f = typeof(aExtension).IsSubclassOf(t.BaseType); bool g = t.IsSubclassOf(typeof(aExtension)); bool h = t.BaseType.IsSubclassOf(typeof(LBT.AdMeter.aExtension)); bool i = t.BaseType.Equals(typeof(aExtension)); bool j = typeof(aExtension).Equals(t.BaseType); T is the reflected Type from the calss UK. Stange thing is i do the exact same thing just on an external assembly in the same application and it works as expected...

  • Overriding CSS properties for iframe width

    - by user2898989
    I'm trying to put an iframe into a webpage, but no matter what I try to put in either the iframe properties or the custom CSS section of the website builder (or how many times I try to add !important to anything from width to right-margin), I can't get the iframe to extend rightward further than the page's preset width. Here's an example of the page and iframe that I'm working with: http://fmlcapitalinvestment.com/Search_Properties.html I need that script/iframe to be wide enough to show the search area. It seems pointless to copy and paste code and attributes I've tried setting, because nothing I do seems to have any effect, but just for showing how much I have no idea what I'm doing, here's my iframe code: <iframe id="idxFrame" style="padding:0; margin:0; padding-top: 0px; overflow-x:auto; width:1000px!important; border:0px solid transparent; background-color:transparent; max-width:none!important; right-margin:-200px!important" frameborder="0" scrolling="on" src="http://www.themls.com/IDXNET/Default.aspx?wid=8MSsp7Pf9eI55yjkDuB%2blX5awn7LnnVXh5PNYhq2ImAEQL" width="1200px" height="900px"></iframe> The "Website Builder" that I'm forced to use to make these kinds of pages is infuriating, but it does have a "Custom CSS" area where I can input additional CSS information. Is there something I could generically use to set iframes to their own widths?

  • Multiple collections tied to one base collection with filters and eventing

    - by damienc88
    I have a complex model served from my back end, which has a bunch of regular attributes, some nested models, and a couple of collections. My page has two tables, one for invalid items, and one for valid items. The items in question are from one of the nested collections. Let's call it baseModel.documentCollection, implementing DocumentsCollection. I don't want any filtration code in my Marionette.CompositeViews, so what I've done is the following (note, duplicated for the 'valid' case): var invalidDocsCollection = new DocumentsCollection( baseModel.documentCollection.filter(function(item) { return !item.isValidItem(); }) ); var invalidTableView = new BookIn.PendingBookInRequestItemsCollectionView({ collection: app.collections.invalidDocsCollection }); layout.invalidDocsRegion.show(invalidTableView); This is fine for actually populating two tables independently, from one base collection. But I'm not getting the whole event pipeline down to the base collection, obviously. This means when a document's validity is changed, there's no neat way of it shifting to the other collection, therefore the other view. What I'm after is a nice way of having a base collection that I can have filter collections sit on top of. Any suggestions?

  • Core Data to-many relationship in code

    - by Jan Bezemer
    I have three entities: Session, User and Test. A session has 0-many users and a user can perform 0-6 tests. (I say 0 but in the real application always at least 1 is required, at least 1 user for a session and at least 1 test for a user. But I say 0 to express an empty start.) All entities have their own specific data attributes too. A user has a name, A session has a name, a test has six values to be filled in by the user, and so on. But my issue is with the relationships. How do I set multiple users and have them added to one session (same goes for multiple tests for one user). How do I show the content in a right way? How do I show a session that has multiple users and these users having completed multiple tests? Here's my code so far with regard to issue 1: Session *session = [NSEntityDescription insertNewObjectForEntityForName:@"Session" inManagedObjectContext:context]; session.name = @"Session 1"; User *users = [NSEntityDescription insertNewObjectForEntityForName:@"User" inManagedObjectContext:context]; users.age = [NSNumber numberWithInt:28]; users.session = session; //sessie.users = users; [sessie addUserObject:users]; With regard to issue 2: I can log the session, but I can't get the user(s) logged from a session. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Session" inManagedObjectContext:context]; [fetchRequest setEntity:entity]; NSArray *fetchedObjects = [context executeFetchRequest:fetchRequest error:&error]; for (Session *info in fetchedObjects) { NSLog(@"Name: %@", info.name); NSLog(@"Having problems with this: %@",info.user); //User *details = info.user; //NSLog(@"User: %@", details.age); }
