  • Custom rowsetClass does not return values

    - by Wesley
    Hi, I'm quite new to Zend and the database classes from it. I'm having problems mapping a Zend_Db_Table_Row_Abstract to my rows. The problem is that whenever I try to map it to a class (Job) that extends the Zend_Db_Table_Row_Abstract class, the database data is not receivable anymore. I'm not getting any errors, trying to get data simply returns null. Here is my code so far: Jobs: class Jobs extends Zend_Db_Table_Abstract { protected $_name = 'jobs'; protected $_rowsetClass = "Job"; public function getActiveJobs() { $select = $this->select()->where('jobs.jobDateOpen < UNIX_TIMESTAMP()')->limit(15,0); $rows = $this->fetchAll($select); return $rows; } } Job: class Job extends Zend_Db_Table_Row_Abstract { public function getCompanyName() { //Gets the companyName } } Controller: $oJobs = new Jobs(); $aActiveJobs = $oJobs->getActiveJobs(); foreach ($aActiveJobs as $value) { var_dump($value->jobTitle); } When I remove the "protected $_rowsetClass = "Job";" line, so that the table row is not mapped to my own class, I get all the jobTitles perfectly. What am I doing wrong here? Thanks in advance, Wesley

  • Why does only youtube embeds work on iPad?

    - by Nagaraj Hubli
    I am trying to find out as to why youtube embeds works just fine on iPad, and not the embeds of any other video site. Example of youtube embed: <object width="640" height="385"> <param name="movie" value="http://www.youtube.com/v/DlIU5TgwEFg&color1=0xb1b1b1&color2=0xcfcfcf&hl=en_US&feature=player_embedded&fs=1"></param> <param name="allowFullScreen" value="true"></param> <param name="allowScriptAccess" value="always"></param> <embed src="http://www.youtube.com/v/DlIU5TgwEFg&color1=0xb1b1b1&color2=0xcfcfcf&hl=en_US&feature=player_embedded&fs=1" type="application/x-shockwave-flash" allowfullscreen="true" allowScriptAccess="always" width="640" height="385"></embed> </object> is this because iPad has got a native youtube app which has special support for youtube embeds, or is this something that is handled by the script that's get executed by the youtube embed code, which might check for the user agent, and then load the HTML5 video player with a source pointing to the h.264 encoded version of the video (is something of this sort possible)?

  • How to put large text data (~20mb) into sql cs 3.5 database?

    - by Anindya Chatterjee
    I am using following query to insert some large text data : internal static string InsertStorageItem = "insert into Storage(FolderName, MessageId, MessageDate, StorageData) values ('{0}', '{1}', '{2}', @StorageData)"; and the code I am using to execute this query is as follows : string content = "very very large data"; string query = string.Format(InsertStorageItem, "Inbox", "AXOGTRR1445/DSDS587444WEE", "4/19/2010 11:11:03 AM"); var command = new SqlCeCommand(query, _sqlConnection); var paramData = command.Parameters.Add("@StorageData", System.Data.SqlDbType.NText); paramData.Value = content; paramData.SourceColumn = "StorageData"; command.ExecuteNonQuery(); But at the last line I am getting this following error : System.Data.SqlServerCe.SqlCeException was unhandled by user code Message=The data was truncated while converting from one data type to another.

  • Why overload true and false instead of defining bool operator?

    - by Joe Enos
    I've been reading about overloading true and false in C#, and I think I understand the basic difference between this and defining a bool operator. The example I see around is something like: public static bool operator true(Foo foo) { return (foo.PropA > 0); } public static bool operator false(Foo foo) { return (foo.PropA <= 0); } To me, this is the same as saying: public static implicit operator bool(Foo foo) { return (foo.PropA > 0); } The difference, as far as I can tell, is that by defining true and false separately, you can have an object that is both true and false, or neither true nor false: public static bool operator true(Foo foo) { return true; } public static bool operator false(Foo foo) { return true; } //or public static bool operator true(Foo foo) { return false; } public static bool operator false(Foo foo) { return false; } I'm sure there's a reason this is allowed, but I just can't think of what it is. To me, if you want an object to be able to be converted to true or false, a single bool operator makes the most sense. Can anyone give me a scenario where it makes sense to do it the other way? Thanks

  • Resize view on iPhone when rotating

    - by BCBomb47
    I have an application with many views. I want only a couple of the views to be able to rotate to landscape when the device is rotated. I found out that I couldn't use (BOOL)shouldAutorotateToInterfaceOrientation because that would rotate every view in my app. I found a solution to this problem here on Stack Overflow but now I have another issue to deal with. The view rotates when I turn the device but it still shows the view as if it were still in portrait mode (straight up and down). The top and bottom of the view is cut off. Is there a way to have the view rotate and also adjust its size to fit the new orientation? I also found this but wasn't able to get it to work. Here's my code for that view: @implementation businessBank @synthesize webView, activityIndicator; - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = @"website_url"; NSURL *url = [NSURL URLWithString:urlAddress]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [webView loadRequest:requestObj]; [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:) name:UIDeviceOrientationDidChangeNotification object:nil]; } - (void)didRotate:(NSNotification *)notification { UIDeviceOrientation orientation = [[notification object] orientation]; if (orientation == UIDeviceOrientationLandscapeLeft) { [self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)]; } else if (orientation == UIDeviceOrientationLandscapeRight) { [self.view setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)]; } else if (orientation == UIDeviceOrientationPortraitUpsideDown) { [self.view setTransform:CGAffine TransformMakeRotation(M_PI)]; } else if (orientation == UIDeviceOrientationPortrait) { [self.view setTransform:CGAffineTransformMakeRotation(0.0)]; } }

  • Date Filtered Collections without Functions

    - by madcapnmckay
    Hi, I have an entity similar to the below: public class Entity { public List<DateItem> PastDates { get; set; } public List<DateItem> FutureDates { get; set; } } public class DateItem { public DateTime Date { get; set; } /* * Other Properties * */ } Where PastDates and FutureDates are both mapped to the same type/table. I have been trying to find a way to have the Past and Future properties mapped automagically by Nhibernate. The closest I came was where clause on the mapping as follows HasMany(x => x.PastDates) .AsBag().Cascade .AllDeleteOrphan() .KeyColumnNames.Add("EventId").Where("Date < currentdate()") .Inverse(); Where currentdate is a UDF. I do not want to have these database specific functions if I can avoid it, mostly because i can't then test my DAL with SQLite as it doesn't support functions or stored procedures. At the moment I am building the past and future collections using Criteria and adding to my DTO manually. Anyone know how this could be achieved without using any UDFs? Many thanks,

  • After drawing circles on C# form how can i know on what circle i clicked?

    - by SorinA.
    I have to represent graphically an oriented graph like in the image below. i have a C# form, when i click with the mouse on it i have to draw a node. If i click somewhere on the form where is not already a node drawn it means i cliked with the intetion of drawing a node, if it is a node there i must select it and memorize it. On the next mouse click if i touch a place where there is not already a node drawn it means like before that i want to draw a new node, if it is a node where i clicked i need to draw the line from the first memorized node to the selected one and add road cost details. i know how to draw the circles that represent the nodes of the graph when i click on the form. i'm using the following code: namespace RepGraficaAUnuiGraf { public partial class Form1 : Form { Graphics graphDrawingArea; Bitmap bmpDrawingArea; Graphics graph; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { bmpDrawingArea = new Bitmap(Width, Height); graphDrawingArea = Graphics.FromImage(bmpDrawingArea); graph = Graphics.FromHwnd(this.Handle); } private void Form1_Click(object sender, EventArgs e) { DrawCentralCircle(((MouseEventArgs)e).X, ((MouseEventArgs)e).Y, 15); graph.DrawImage(bmpDrawingArea, 0, 0); } void DrawCentralCircle(int CenterX, int CenterY, int Radius) { int start = CenterX - Radius; int end = CenterY - Radius; int diam = Radius * 2; bmpDrawingArea = new Bitmap(Width, Height); graphDrawingArea = Graphics.FromImage(bmpDrawingArea); graphDrawingArea.DrawEllipse(new Pen(Color.Blue), start, end, diam, diam); graphDrawingArea.DrawString("1", new Font("Tahoma", 13), Brushes.Black, new PointF(CenterX - 8, CenterY - 10)); } } } My question is how can i find out if at the coordinates (x,y) on my form i drew a node and which one is it? I thought of representing the nodes as buttons, having a tag or something similar as the node number(which in drawing should be 1 for Santa Barbara, 2 for Barstow etc.)

  • How to access a superclass's class attributes in Python?

    - by Brecht Machiels
    Have a look at the following code: class A(object): defaults = {'a': 1} def __getattr__(self, name): print('A.__getattr__') return self.get_default(name) @classmethod def get_default(cls, name): # some debug output print('A.get_default({}) - {}'.format(name, cls)) try: print(super(cls, cls).defaults) # as expected except AttributeError: #except for the base object class, of course pass # the actual function body try: return cls.defaults[name] except KeyError: return super(cls, cls).get_default(name) # infinite recursion #return cls.__mro__[1].get_default(name) # this works, though class B(A): defaults = {'b': 2} class C(B): defaults = {'c': 3} c = C() print('c.a =', c.a) I have a hierarchy of classes each with its own dictionary containing some default values. If an instance of a class doesn't have a particular attribute, a default value for it should be returned instead. If no default value for the attribute is contained in the current class's defaults dictionary, the superclass's defaults dictionary should be searched. I'm trying to implement this using the recursive class method get_default. The program gets stuck in an infinite recursion, unfortunately. My understanding of super() is obviously lacking. By accessing __mro__, I can get it to work properly though, but I'm not sure this is a proper solution. I have the feeling the answer is somewhere in this article, but I haven't been able to find it yet. Perhaps I need to resort to using a metaclass?

  • ASP.NET - I am generating an .XLS file with a DLL, how do I grant permissions for writing to file? (

    - by hamlin11
    I'm generating an .XLS file with a DLL (Excel Library http://code.google.com/p/excellibrary/) I've added this DLL as a reference to my project. The code to save the .XLS to disk is running, but it's encountering a permissions issue.

  • Return an empty collection when Linq where returns nothing

    - by ahsteele
    I am using the below statement with the intent of getting all of the machine objects from the MachineList collection (type IEnumerable) that have a MachineStatus of i. The MachineList collection will not always contain machines with a status of i. At times when no machines have a MachineStatus of i I'd like to return an empty collection. My call to ActiveMachines (which is used first) works but InactiveMachines does not. public IEnumerable<Machine> ActiveMachines { get { return Customer.MachineList .Where(m => m.MachineStatus == "a"); } } public IEnumerable<Machine> InactiveMachines { get { return Customer.MachineList .Where(m => m.MachineStatus == "i"); } } Edit Upon further examination it appears that any enumeration of MachineList will cause subsequent enumerations of MachineList to throw an exeception: Object reference not set to an instance of an object. Therefore, it doesn't matter if a call is made to ActiveMachines or InactiveMachines as its an issue with the MachineList collection. This is especially troubling because I can break calls to MachineList simply by enumerating it in a Watch before it is called in code. At its lowest level MachineList implements NHibernate.IQuery being returned as an IEnumerable. What's causing MachineList to lose its contents after an initial enumeration?

  • Mouse move panning

    - by Rudy
    Hi all, I'm trying to scroll a series of thumbnails horizontally based on the mouseX position. I can get it to scroll but it's very choppy and for some reason it's not reading my start and end numbers so it will stop scrolling. Can anyone point me in the right direction? Thanks. var thumbBounds:Object = new Object(); thumbBounds = thumbContainer.getBounds(this); thumbContainer.addEventListener(MouseEvent.MOUSE_OVER, setScrolling); private function setScrolling(me:MouseEvent):void { thumbContainer.removeEventListener(MouseEvent.MOUSE_OVER, setScrolling); stage.addEventListener(Event.ENTER_FRAME, scrollThumbs); } private function scrollThumbs(e:Event):void { if(mouseX <= thumbBounds.x || mouseX thumbBounds.width || mouseX < thumbBounds.y || mouseX thumbBounds.height) { thumbContainer.addEventListener(MouseEvent.MOUSE_OVER, setScrolling); stage.removeEventListener(Event.ENTER_FRAME, scrollThumbs); } if(thumbContainer.x = 0) { thumbContainer.x = 0; } if(thumbContainer.x <= -842) { thumbContainer.x = -842; } var xdist:Number = new Number(); xdist = mouseX - 382; thumbContainer.x += Math.round(-xdist / 10); }

  • Modeling multiple polymorphic relationships using Hibernate

    - by f-potter
    Ruby on Rails has polymorphic relations which are really useful for implementing functionality such as commenting, tagging and rating to name a few. We can have a comment, tag or rating class which has a many to one polymorphic relationship with a commentable, taggable and rateable object. Also, a given domain object can choose to implement any combination of such relations. So, it can for example be commentable, taggable and rateable at the same time. I couldn't think up of a straightforward way to duplicate this functionality in Hibernate. Ideally, there would be a Comment class which will have a many to one relationship with a Commentable class and a Commentable class will conversely have a one to many relationship with Comments. It will be ideal if the concrete domain classes can inherit from a number of such classes, say Commentable and Taggable. Things seem a little complicated as a Java class can only extend one other class and some code might end up being duplicated across a number of classes. I wanted to know what are the best practices for modeling such relationships neatly and concisely using Hibernate?

  • How to select the first property with unknown name and first item from array in JSON

    - by Oscar Godson
    I actually have two questions, both are probably simple, but for some odd reason I cant figure it out... I've worked with JSON 100s of times before too! but here is the JSON in question: {"69256":{ "streaminfo":{ "stream_ID":"1025", "sourceowner_ID":"2", "sourceowner_avatar":"http:\/\/content.nozzlmedia.com\/images\/sourceowner_avatar2.jpg", "sourceownertype_ID":"1", "stream_name":"Twitter", "streamtype":"Social media" "appsarray":[] }, "item":{ "headline":"Charboy", "main_image":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "summary":"ate a tomato and avocado for dinner...", "nozzl_captured":"2010-05-12 23:02:12", "geoarray":[{ "state":"OR", "county":"Multnomah", "city":"Portland", "neighborhood":"Downtown", "zip":"97205", "street":"462 SW 11th Ave", "latitude":"45.5219", "longitude":"-122.682" }], "full_content":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "body_text":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "author_name":"Charboy", "author_avatar":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "fulltext_url":"http:\/\/twitter.com\/charboy\/statuses\/13889868936", "leftovers":{ "twitter_id":"tag:search.twitter.com,2005:13889868936", "date":"2010-05-13T02:59:59Z", "location":"iPhone: 45.521866,-122.682262" }, "wordarray":{ "0":"ate", "1":"tomato", "2":"avocado", "3":"dinner", "4":"tonight", "5":"tasty", "6":"foods", "7":"just", "8":"enjoyable", "9":"Charboy", "11":"Twitter", "13":"state:OR", "14":"county:Multnomah, OR", "15":"city:Portland, OR", "16":"neighborhood:Downtown", "17":"zip:97205" } } } } Question 1: How do I loop through each item (69256) when the number is random? e.g. item 1 is 123, item2 is 646? Like, for example, a normal JSON feed would have something like: {'item':{'blah':'lorem'},'item':{'blah':'ipsum'}} the JS would be like console.log(item.blah) to return lorem then ipsum in a loop How do I do it when i dont know the first item of the object? Question 2: How do I select items from the geoarray object? I tried: json.test.item.geoarray.latitude and json.test.item.geoarray['latitude']

Usually the event works fine. the problem is with this page:http://www.voiproblem.com/emulators/Netgear/WGR614v6/fw_forward.html when I (automatically) press on "add" the control navigates to:http://www.voiproblem.com/emulators/Netgear/WGR614v6/pforward.html. but it never firing the DocumentComplited event. I build a simple application that does the same and there it works fine. I mean when the app invokes InvokeMember("click") it does go to the DocumentComplited event. in my real app it doesnt. anyone can help me to figure it up what is the problem? thanks. <code> private void button1_Click(object sender, EventArgs e) { webBrowser1.Navigate("http://www.voiproblem.com/emulators/Netgear/WGR614v6/fw_forward.html"); } private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { HtmlElement elm = webBrowser1.Document.GetElementById("Add"); if (elm != null) webBrowser1.Document.GetElementById("Add").InvokeMember("click"); } </code>

  • iPhone - Memory Management - Using Leaks tool and getting some bizarre readings.

    - by Robert
    Hey all, putting the finishing touches on a project of mine so I figured I would run through it and see if and where I had any memory leaks. Found and fixed most of them but there are a couple of things regarding the memory leaks and object alloc that I am confused about. 1) There are 2 memory leaks that do not show me as responsible. There are 8 leaks attributed to AudioToolbox with the function being RegisterEmbeddedAudioCodecs(). This accounts for about 1.5 kb of leaks. The other one is detected immediately when the app begins. Core Graphics is responsible with the extra info being open_handle_to_dylib_path. For the audio leak I have looked over my audio code and to me it seems ok. self.musicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:songFilePath] error:NULL]; [musicPlayer prepareToPlay]; [musicPlayer play] is called later on in a function. 2) Is it normal for there to be a spike in Object Allocation whenever a new view or controller is presented? My total memory usage is very, very low except for whenever I present a view controller. It spikes then immediately goes back down. I am guessing that this is just the phone handling all the information for switching or something. Blegh. Wall of text. Thanks in advance to anyone who helps! =)

  • Putting BigDecimal data into HSQLDB test database using DbUnit

    - by Denise
    Hi everyone, I'm using Hibernate JPA in my backend. I am writing a unit test using JUnit and DBUnit to insert a set of data into an in-memory HSQL database. My dataset contains: <order_line order_line_id="1" quantity="2" discount_price="0.3"/> Which maps to an OrderLine Java object where the discount_price column is defined as: @Column(name = "discount_price", precision = 12, scale = 2) private BigDecimal discountPrice; However, when I run my test case and assert that the discount price returned equals 0.3, the assertion fails and says that the stored value is 0. If I change the discount_price in the dataset to be 0.9, it rounds up to 1. I've checked to make sure HSQLDB isn't doing the rounding and it definitely isn't because I can insert an order line object using Java code with a value like 5.3 and it works fine. To me, it seems like DBUtils is for some reason rounding the number I've defined. Is there a way I can force this to not happen? Can anyone explain why it might be doing this? Thanks!

Does anyone know how I can have the input tag fall inside the tr tag therefore giving me valid XHTML 1.0 STRICT markup? Thanks

  • Flex HttpService POST limited to 543 Byte per Form field?

    Hi, I am getting a FaultEvent when trying to send form fields through HTTPService that contain more than 542 chars. Initializing the HttpService: httpServ = new HTTPService(); httpServ.method = 'POST'; httpServ.url = ENDPOINT_URL; //http://localhost:3001/ReportError.aspx httpServ.resultFormat = HTTPService.RESULT_FORMAT_TEXT; httpServ.contentType = HTTPService.CONTENT_TYPE_FORM; httpServ.addEventListener(ResultEvent.RESULT, OnErrorSent); httpServ.addEventListener(FaultEvent.FAULT, OnFault); Sending the request: var params:Object = {}; //params["stack"] = e.stackTrace.slice(0, 542); //length 542 = works //params["stack2"] = e.stackTrace.slice(1, 543); //length 542 = works (just to show that it's not about the content itself) params["stack3"] = e.stackTrace.slice(0, 543); //length 543 = fails I also seem to be able to create many form fields (with 542 length) so that it's not a limit of the request itself but of the form field: var params:Object = {}; params["stack"] = e.stackTrace.slice(0, 542); //length 542 params["stack2"] = e.stackTrace.slice(1, 543); //length 542 params["stack3"] = e.stackTrace.slice(2, 544); //length 542 // Length > 1600 chars The receiving party is an ASP.NET 4 site on the same domain and port. I hope someone already came across a similar restrictions or has some general advice on how to trace this problem down further. Thanks in advance.

    In my business layer, I need many, many methods that follow the pattern: public BusinessClass PropertyName { get { if (this.m_LocallyCachedValue == null) { if (this.Record == null) { this.m_LocallyCachedValue = new BusinessClass( this.Database, this.PropertyId); } else { this.m_LocallyCachedValue = new BusinessClass( this.Database, this.Record.ForeignKeyName); } } return this.m_LocallyCachedValue; } } I am still learning C#, and I'm trying to figure out the best way to write this pattern once and add methods to each business layer class that follow this pattern with the proper types and variable names substituted. BusinessClass is a typename that must be substituted, and PropertyName, PropertyId, ForeignKeyName, and m_LocallyCachedValue are all variables that should be substituted for. Are attributes usable here? Do I need reflection? How do I write the skeleton I provided in one place and then just write a line or two containing the substitution parameters and get the pattern to propagate itself? EDIT: Modified my misleading title -- I am hoping to find a solution that doesn't involve code generation or copy/paste techniques, and rather to be able to write the skeleton of the code once in a base class in some form and have it be "instantiated" into lots of subclasses as the accessor for various properties. EDIT: Here is my solution, as suggested but left unimplemented by the chosen answerer. // I'll write many of these... public BusinessClass PropertyName { get { return GetSingleRelation(ref this.m_LocallyCachedValue, this.PropertyId, "ForeignKeyName"); } } // That all call this. public TBusinessClass GetSingleRelation<TBusinessClass>( ref TBusinessClass cachedField, int fieldId, string contextFieldName) { if (cachedField == null) { if (this.Record == null) { ConstructorInfo ci = typeof(TBusinessClass).GetConstructor( new Type[] { this.Database.GetType(), typeof(int) }); cachedField = (TBusinessClass)ci.Invoke( new object[] { this.Database, fieldId }); } else { var obj = this.Record.GetType().GetProperty(objName).GetValue( this.Record, null); ConstructorInfo ci = typeof(TBusinessClass).GetConstructor( new Type[] { this.Database.GetType(), obj.GetType()}); cachedField = (TBusinessClass)ci.Invoke( new object[] { this.Database, obj }); } } return cachedField; }

  • Cross-domain templating with Javascript

    - by Husky
    I'm currently building a Javascript library that can be used to easily create embeddable media based on the URL of a media file, and then be controlled using Javascript methods and events (think something like the Flash / Silverlight JW player). Of course, i could simply cat all the html tags from the Javascript library and send that to the browser: function player(url) { document.write('<object type="foo"><param name="something" value="bar">' + <param name="source" value=" + url + '/></object>'); } But i think this is a very ugly practice that tends to create unmanageable code that is unreadable when you review it a few weeks later. So, a templating solution seems to be the way to go. I've been looking to EJS because it loads the templates using AJAX, so you can manage your templates in separate file instead of directly on the HTML page. There's one 'gotcha' with that: my library needs to be completely cross-domain: the library itself could be located on foo.com while the serving site could be located on bar.com. So if bar.com would want to add a media player using the library it needs to do an AJAX call to a template located on foo.com, which won't work because of the same-origin policy in browsers. AFAIK, there's no library that uses something like JSONP to read and write templates to get around this problem. Could anyone point me to a solution for this problem?

  • NHibernate IQueryable Collection as Property of Root

    - by Khalid Abuhakmeh
    Hello and thank you for taking the time to read this. I have a root object that has a property that is a collection. For example : I have a Shelf object that has Books. // now public class Shelf { public ICollection<Book> Books {get; set;} } // want public class Shelf { public IQueryable<Book> Books {get;set;} } What I want to accomplish is to return a collection that is IQueryable so that I can run paging and filtering off of the collection directly from the the parent. var shelf = shelfRepository.Get(1); var filtered = from book in shelf.Books where book.Name == "The Great Gatsby" select book; I want to have that query executed specifically by NHibernate and not a get all to load a whole collection and then parse it in memory (which is what currently happens when I use ICollection). The reasoning behind this is that my collection could be huge, tens of thousands of records, and a get all query could bash my database. I would like to do this implicitly so that when NHibernate sees and IQueryable on my class it knows what to do. I have looked at NHibernates Linq provider and currently I am making the decision to take large collections and split them into their own repository so that I can make explicit calls for filtering and paging. Linq To SQL offers something similar to what I'm talking about.

  • Extensionless URLs in IIS 6

    - by Jason Marsell
    My client has asked me to build a personalized URL system so that they can send out really short URLs in postcards to customers like this: www.client.com/JasonSmith03 www.client.com/TonyAdams With these URLs, I need IIS 6 to trap the incoming request and pass that “JasonSmith03” token to my database to determine which landing page to redirect them to. I’d love to use an HttpHandler or HttpModule but they both look like they require an file extension (.aspx) in the URL. Wildcard mapping will chew up every incoming request and that’s ridiculous. ISAPI filters are just text routing files, so I can’t employ logic to call the database. According to Scott Guthrie, this would be cake if I had IIS 7, but I don’t. Can this be done using MVC? I’ve been working with MVP for the last few years, so I haven’t done any MVC and routing. I thought I remembered that MVC has the ability to use REST-style extensionless URLs. I’d be more than happy to have these personalized URLs land on a site that’s built in MVC, if it will work. Thank you!

  • Really simple JSON serialization in .NET

    - by Evgeny
    I have some simple .NET objects I'd like to serialize to JSON and back again. The set of objects to be serialized is quite small and I control the implementation, so I don't need a generic solution that will work for everything. Since my assembly will be distributed as a library I'd really like to avoid a dependency on some third-party DLL: I just want to give users one assembly that they can reference. I've read the other questions I could find on converting to and from JSON in .NET. The recommended solution of JSON.NET does work, of course, but it requires distributing an extra DLL. I don't need any of the fancy features of JSON.NET. I just need to handle a simple object (or even dictionary) that contains strings, integers, DateTimes and arrays of strings and bytes. On deserializing I'm happy to get back a dictionary - it doesn't need to create the object again. Is there some really simple code out there that I could compile into my assembly to do this simple job? I've also tried System.Web.Script.Serialization.JavaScriptSerializer, but where it falls down is the byte array: I want to base64-encode it and even registering a converter doesn't let me easily accomplish that due to the way that API works (it doesn't pass in the name of the field).

  • Dependency Injection for objects that require parameters

    - by Andrew
    All of our reports are created from object graphs that are translated from our domain objects. To enable this, we have a Translator class for each report, and have been using Dependency Injection for passing in dependencies. This worked great, and would yield nice classes structured like this: public class CheckTranslator : ICheckTranslator { public CheckTranslator (IEmployeeService empSvc , IPaycheckService paySvc) { _empSvc = empSvc; _paySvc = paySvc; } public Check CreateCheck() { //do the translation... } } However, in some cases the mapping has many different grouping options. As a result, the c-tor would turn into a mix of class dependencies and parameters. public class CheckTranslator : ICheckTranslator { public CheckTranslator (IEmployeeService empSvc , IPaycheckService paySvc , bool doTranslateStubData , bool doAttachLogo) { _empSvc = empSvc; _paySvc = paySvc; _doTranslateStubData = doTranslateStubData; _doAttachLogo = doAttachLogo; } public Check CreateCheck() { //do the translation... } } Now, we can still test it, but it no longer really works with an IoC container, at least in a clean fashion. Plus, we can no longer call the CreateCheck twice if the settings are different for each check. While I recognize it's a problem, I don't necessarily see the right solution. It seems kind of strange to create a Factory for each class ... or is this the best way?
