  • How to find unique values in jagged array

    - by David Liddle
    I would like to know how I can count the number of unique values in a jagged array. My domain object contains a string property that has space delimitered values. class MyObject { string MyProperty; //e.g = "v1 v2 v3" } Given a list of MyObject's how can I determine the number of unique values? The following linq code returns an array of jagged array values. A solution would be to store a temporary single array of items, looped through each jagged array and if values do not exist, to add them. Then a simple count would return the unique number of values. However, was wondering if there was a nicer solution. db.MyObjects.Where(t => !String.IsNullOrEmpty(t.MyProperty)) .Select(t => t.Categories.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries)) .ToArray() Below is a more readable example: array[0] = { "v1", "v2", "v3" } array[1] = { "v1" } array[2] = { "v4", "v2" } array[3] = { "v1", "v5" } From all values the unique items are v1, v2, v3, v4, v5. The total number of unique items is 5. Is there a solution, possibly using linq, that returns either only the unique values or returns the number of unique values?

  • Flex AS3 - Creating a dynamic property, and then binding a control to it

    - by Caleb Cittadino
    I am trying to: 1) create a dynamic property 2) bind that property to a label This works great for "sealed properties", but for dynamic properties there doesn't appear to be any event triggered. Are dynamic properties implicityly not bindable? var myObj:MyType = new MyType(); // MyType is dynamic myObj["myDynamicPropertyName"] = "initialized"; BindingUtils.bindProperty(myLabel, "data", myObj, repeatedLabel.name); // myLabel now displays "initialized" myObj["myDynamicPropertyName"] = "changed"; // myLabel still displays "initialized", it should say "changed" !!!

  • Dynamic 'twitter style' urls with ASP.NET

    - by Desiny
    I am looking to produce an MVC site which has complete control of the url structure using routing. The specific requirements are: www.mysite.com/ = homepage (home controller) www.mysite.com/common/about = content page (common controller) www.mysite.com/common/contact = content page (common controller) www.mysite.com/john = twitter style user page (dynamic controller) www.mysite.com/sarah = twitter style user page (dynamic controller) www.mysite.com/me = premium style user page (premium controller) www.mysite.com/oldpage.html = 301 redirect to new page www.mysite.com/oldpage.asp?id=3333 = 301 redirect to new page My routes look as follows: routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Common", "common/{action}/{id}", new { controller = "common", action = "Index", id = "" } ); routes.MapRoute( "Home", "", new { controller = "Home", action = "Index", id = "" } ); routes.MapRoute( "Dynamic", "{id}", new { controller = "dynamic", action = "Index", id = "" } ); In order to handle the 301 rredirct, I have a database defining the old pages and their new page urls and a stored procdure to handle the lookup. The code (handler) looks like this: public class AspxCatchHandler : IHttpHandler, IRequiresSessionState { #region IHttpHandler Members public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext context) { if (context.Request.Url.AbsolutePath.Contains("aspx") && !context.Request.Url.AbsolutePath.ToLower().Contains("default.aspx")) { string strurl = context.Request.Url.PathAndQuery.ToString(); string chrAction = ""; string chrDest = ""; try { DataTable dtRedirect = SqlFactory.Execute( ConfigurationManager.ConnectionStrings["emptum"].ConnectionString, "spGetRedirectAction", new SqlParameter[] { new SqlParameter("@chrURL", strurl) }, true); chrAction = dtRedirect.Rows[0]["chrAction"].ToString(); chrDest = dtRedirect.Rows[0]["chrDest"].ToString(); chrDest = context.Request.Url.Host.ToString() + "/" + chrDest; chrDest = "http://" + chrDest; if (string.IsNullOrEmpty(strurl)) context.Response.Redirect("~/"); } catch { chrDest = "/";// context.Request.Url.Host.ToString(); } context.Response.Clear(); context.Response.Status = "301 Moved Permanently"; context.Response.AddHeader("Location", chrDest); context.Response.End(); } else { string originalPath = context.Request.Path; HttpContext.Current.RewritePath("/", false); IHttpHandler httpHandler = new MvcHttpHandler(); httpHandler.ProcessRequest(HttpContext.Current); HttpContext.Current.RewritePath(originalPath, false); } } #endregion } It is very simple to look up a user and in fact the above code does this. My problem is in the dynamic / premium part. I am trying to do the following: 1) in the dynamic controller, lookup the username. 2) if the username is in the user list (database), show the Index ActionResult of the Dynamic controller. 3) if the username is not found, look up the username in the premium list 4) if the username is fund in the premium list (database) then show the Index ActionResult of the Preium controller. 5) If all else fails jump to the 404 page (which will ask the user to sign up) Is this possible? Looking up the user twice is a bad idea for performance? How do I do this without redirecting?

  • Declaring a string array in class header file - compiler thinks string is variable name?

    - by Dave
    Hey everybody, I need a bit of a hand with declaring a string array in my class header file in C++. atm it looks like this: //Maze.h #include <string> class Maze { GLfloat mazeSize, mazeX, mazeY, mazeZ; string* mazeLayout; public: Maze ( ); void render(); }; and the constructor looks like this: //Maze.cpp #include <GL/gl.h> #include "Maze.h" #include <iostream> #include <fstream> Maze::Maze( ) { cin >> mazeSize; mazeLayout = new string[mazeSize]; mazeX = 2/mazeSize; mazeY = 0.25; mazeZ = 2/mazeSize; } I'm getting a compiler error that says: In file included from model-view.cpp:11: Maze.h:14: error: ISO C++ forbids declaration of ‘string’ with no type Maze.h:14: error: expected ‘;’ before ‘*’ token and the only sense that makes to me is that for some reason it thinks I want string as a variable name not as a type declaration. If anybody could help me out that would be fantastic, been looking this up for a while and its giving me the shits lol. Cheers guys

  • asp repeater inside dynamic control losing items

    - by Ed
    i have a repeater inside a dynamic control, i am trying to get the items of the repeater in a postback prior to databinding. this seems to work when i have a static repeater where the items are still intact, but when my repeater is inside a dynamic control and i try to get "repeater.Items", the count is always 0. is this normal behavior for repeaters when being placed inside a dynamic control?

  • How do I use an array as an object attribute in Perl?

    - by superstar
    Hello guys, I need some help regarding the arrays in Perl This is the constructor i have. sub new { my $class = shift; my @includeobjects = (); my @excludeobjects = (); my $Packet = { _PacketName => shift, _Platform => shift, _Version => shift, @_IncludePath => @includeobjects, }; bless $Packet, $class; return $Packet; } sub SetPacketName { my ( $Packet, $PacketName ) = @_; $Packet->{_PacketName} = $PacketName if defined($PacketName); return $Packet->{_PacketName}; } sub SetIncludePath { my ( $Packet, @IncludePath ) = @_; $Packet->{@_IncludePath} = @IncludePath; return $Packet->{@_IncludePath}; } sub GetPacketName { my( $Packet ) = @_; return $Packet->{_PacketName}; } sub GetIncludePath { my( $Packet ) = @_; return $Packet->{@_IncludePath}; } The get and set methods work fine for PacketName. But since IncludePath is an array, I could not get it work. The declaration is what I am not able to get right.

  • Populate tableView with more than one array

    - by Ewoods
    The short version: Is there a way to populate one specific row in a tableView with one value from one array, then populate another row in that same tableView with one value from a different array? For example, cell 1 would have the first value from Array A, cell 2 would have the first value from Array B, cell 3 would have the first value from Array C, etc. The long version: I hope this isn't too confusing. I've got an array of names, and then three more arrays with actions associated with those people. For example, the names array has Jim, Bob, and Sue, and then there's an array for eating, reading, and sleeping that records every time each person does one of these things (all of these arrays are populated from a MySQL database). The names array is used to populate a root tableView. Tapping on one of the names brings up a detail view controller that has another tableView that only has three rows. This part is all working fine. What I want to happen is when I tap on a name, it moves to the detail view and the three cells would then show the last event for that person for each of the three activities. Tapping on one of those three events then moves to a new view controller with a tableView that shows every event for that category. For example, if I tapped on Bob, the second page would show the last time Bob ate, read, and slept. Tapping on the first row would bring up a table that showed every time Bob has eaten. So far I've only been able to populate the second tableView with all of the rows from one of the arrays. I need it the other way around (one row from all of the arrays).

  • Codeigniter - accessing variables from an array passed into a page.

    - by Matt
    Hello, I have a controller with an index function as follows: function index() { $this->load->model('products_model'); $data['product'] = $this->products_model->get(3); // 3 = product id $data['product_no'] = 3; $data['main_content'] = 'product_view'; //print_r($data['products']); $this->load->view('includes/template', $data); } This is the get function in the products_model file function get($id) { $results = $this->db->get_where('products', array('id' => $id))->result(); //get the first item $result = $results[0]; return $result; } The products table contains fields such as name, price etc. Please can you tell me how to output variables from $data['product'] after it is passed into the view? I have tried so many things but nothing is working, even though the print_r (commented out) shows the data - it is not being passed into the view. I thought it may have been because the view calls a template file which references the main_content variable: Template file contents: <?php $this->load->view('includes/header'); ?> <?php $this->load->view($main_content); ?> <?php $this->load->view('includes/footer'); ?> but i tried creating a flat view file and still couldn't access the variables. Many thanks,

  • constructing a recursive function returning an array

    - by Admiral Kunkka
    I'm developing a function that has a random chance to loop through itself and put it's results in one array for me to use later in my PHP class. Is there a better way to do this more organized, specifically case 5. The array becomes sloppy if it rolls 5, after 5, after 5 looking unpleasant. private function dice($sides) { return mt_rand(1, $sides); } private function randomLoot($dice) { switch($dice) { case 1: $array[] = "A fancy mug."; break; case 2: $array[] = "A buckler."; break; case 3: $array[] = "A sword."; break; case 4: $array[] = "A jewel."; break; case 5: $array[] = "A treasure chest with contents:"; $count = $this->dice(3); $i = 1; while($i <= $count) { $array[] = $this->randomLoot($this->dice(5)); $i++; } break; } return $array; }

  • Convert a Dynamic[] construct to a numerical list

    - by Leo Alekseyev
    I have been trying to put together something that allows me to extract points from a ListPlot in order to use them in further computations. My current approach is to select points with a Locator[]. This works fine for displaying points, but I cannot figure out how to extract numerical values from a construct with head Dynamic[]. Below is a self-contained example. By dragging the gray locator, you should be able to select points (indicated by the pink locator and stored in q, a list of two elements). This is the second line below the plot. Now I would like to pass q[[2]] to a function, or perhaps simply display it. However, Mathematica treats q as a single entity with head Dynamic, and thus taking the second part is impossible (hence the error message). Can anyone shed light on how to convert q into a regular list? EuclideanDistanceMod[p1_List, p2_List, fac_: {1, 1}] /; Length[p1] == Length[p2] := Plus @@ (fac.MapThread[Abs[#1 - #2]^2 &, {p1, p2}]) // Sqrt; test1 = {{1.`, 6.340196001221532`}, {1.`, 13.78779876355869`}, {1.045`, 6.2634018978377295`}, {1.045`, 13.754947081416544`}, {1.09`, 6.178367702583522`}, {1.09`, 13.72055251752498`}, {1.135`, 1.8183153704413153`}, {1.135`, 6.082497198000075`}, {1.135`, 13.684582525399742`}, {1.18`, 1.6809452373465104`}, {1.18`, 5.971583107298081`}, {1.18`, 13.646996905469383`}, {1.225`, 1.9480537697339537`}, {1.225`, 5.838386922625636`}, {1.225`, 13.607746407088161`}, {1.27`, 2.1183174369679234`}, {1.27`, 5.669799095595362`}, {1.27`, 13.566771130126131`}, {1.315`, 2.2572975468163463`}, {1.315`, 5.444014254828522`}, {1.315`, 13.523998701347882`}, {1.36`, 2.380307009155079`}, {1.36`, 5.153024664297602`}, {1.36`, 13.479342200528283`}, {1.405`, 2.4941312539733285`}, {1.405`, 4.861423833512566`}, {1.405`, 13.432697814928654`}, {1.45`, 2.6028066447609426`}, {1.45`, 4.619367407525507`}, {1.45`, 13.383942212133244`}}; DynamicModule[{p = {1.2, 10}, q = {1.3, 11}}, q := Dynamic@ First@test1[[ Ordering[{#, EuclideanDistanceMod[p, #, {1, .1}]} & /@ test1, 1, #1[[2]] < #2[[2]] &]]]; Grid[{{Show[{ListPlot[test1, Frame -> True, ImageSize -> 300], Graphics@Locator[Dynamic[p]], Graphics@ Locator[q, Appearance -> {Small}, Background -> Pink]}]}, {Dynamic@p}, {q},{q[[2]]}}]]

  • Java queue and multi-dimention array question? [Beginner level]

    - by javaLearner.java
    First of all, this is my code (just started learning java): Queue<String> qe = new LinkedList<String>(); qe.add("b"); qe.add("a"); qe.add("c"); qe.add("d"); qe.add("e"); My question: Is it possible to add element to the queue with two values, like: qe.add("a","1"); // where 1 is integer So, that I know element "a" have value 1. If I want to add a number let say "2" to element a, I will have like a = 3. If this cant be done, what else in java classes that can handle this? I tried to use multi-dimention array, but its kinda hard to do the queue, like pop, push etc. (Maybe I am wrong) How to call specific element in the queue? Like, call element a, to check its value. [Note] Please don't give me links that ask me to read java docs. I was reading, and I still dont get it. The reason why I ask here is because, I know I can find the answer faster and easier.

  • how do I make my submenu position dynamic based on the distance to the edge of the window?

    - by Mario Antoci
    I'm trying to write a jQuery script that will find the distance to the right edge of the browser window from my css class element and then position the child submenu dropdowns to the right or left depending on the available space to the right. Also it needs to revert to the default settings on hoverout. Here is what I have so far but it's not calculating properly. $(document).ready(function(){ $('#dnnMenu .subLevel').hover(function(){ if ($(window).width() - $('#dnnMenu .subLevel').offset().left - '540' >= '270') { $('#dnnMenu .subLevelRight').css('left', '270px');} else {$('#dnnMenu .subLevelRight').css('left', '-270px');} }); $(document).ready(function () { function HoverOver() { $(this).addClass('hover'); } function HoverOut() { $(this).removeClass('hover'); } var config = { sensitivity: 2, interval: 100, over: HoverOver, timeout: 100, out: HoverOut }; $("#dnnMenu .topLevel > li.haschild").hoverIntent(config); $(".subLevel li.haschild").hover(HoverOver, HoverOut); }); Basically I tried to take the width of the current window, minus the distance to the left edge of the browser of the first level submenu, minus the width of both elements together which would equal 540px, to calculate the distance to the right edge of the window when the first level submenu is hovered over. if the distance to the right of my first level submenu element is less than 540px then the second level sub menu css property is changed to position to the left instead of right. I also know that it needs to revert back to default after hover out so it can recalculate the distance from other positions within the menu structure and still have those second level submenus with enough room to still display on the right of the first level. here is css for the elements in question. #dnnMenu .subLevel{ display: none; position: absolute; margin: 0; z-index: 1210; background: #639ec8; text-transform: none;} #dnnMenu .subLevelRight{ position: absolute; display: none; left: 270px; top: 0px;} The site's not live yet and I tried to create a jsfiddle but it doesn't look right. Any help would be greatly appreciated! Best Regards, Mario

  • How can I use different metadata for a Dynamic Data form view and the list view?

    - by ProfK
    We often need a summarised list view with more detailed form view. So far, the only two way I can think of doing this are using a 'custom' list or form view than uses a sumplimentary 'remove' or 'add' list of fields anb generalise this over all entity sets, or create a custom metadata provider that infers somehow which columns to supply. Are there any other ways of distinguishing these two views? PS, I wrote a fun little general details page, that handles insert, edit, and view, all on one page template. Maybe I could somehow use that? It's here.

  • How do I resize an iframe with dynamic content?

    - by Middletone
    I'm populating an iframe with some contents that are injected into it but I'm unable to size it correctly. I've tried a variety of methods but here is the most recent code. After populating the iframe with an html based mail message it doesn't seem to register the scroll height. <iframe scrolling="no" width="100%" onload="javascript:(LoadIFrame(this));" > HTML content goes here. Make sure it's long enough to need to scroll before testing. </iframe> <script type="text/javascript"> function LoadIFrame(iframe) { $("iframe").each(function() { $(this).load(function() { var doc = this.document; if (this.contentDocument) { doc = this.contentDocument; } else if (this.contentWindow) { doc = this.contentWindow.document; } else if (this.document) { doc = this.document; } this.height = (doc.body.scrollHeight + 50) + 'px'; this.onload = ''; }); txt = $(this).text(); var doc = this.document; if (this.contentDocument) { doc = this.contentDocument; } else if (this.contentWindow) { doc = this.contentWindow.document; } else if (this.document) { doc = this.document; } doc.open(); doc.writeln(txt); doc.close(); }); } </script>

  • Pass dynamic value in URL with CakePHP

    - by Renato Dinhani Conceição
    I have the following method that performs an Ajax request passing some dynamic value obtained from a select input. It works fine, but the dynamic value is passed as parameter in the URL, something like states/listCities/?big_string_of_serialized_parameter . $this->Js->event( 'change', $this->Js->request( array( #url 'controller' => 'states', 'action' => 'listCities'), array( # ajax options that generates the serialized parameter 'update' => '#DealerCityId', 'data' => '$("#DealerStateId").serialize()', 'dataExpression' => true ) ) ); I'm trying to do this in a more friendly URL way, something like states/listCities/2. It's possible in CakePHP to generate a friendly URL like this with dynamic value from a input or is only possible passing the dynamic values as parameters?

  • Writing .NET in dynamic language?

    - by tillda
    I'm confused by the possibility of writing .NET in dynamic languages, such as (Iron)Ruby. Particularly, I've seen code in IronRuby that used generics (...foo[String]), but I'm not aware of this feature in Ruby as it seems nonsense to me in dynamic languages. So, when I write .NET app in IronRuby, how is it with type safety and compilation? I thought that it is just as dynamic as Ruby everywhere else. I thought that if the Ruby syntax is OK all the type checking would be done at the runtime. Also, as far as I know, .NET itself is type-oriented - there are classes that heavily utilize the mentioned generics. How is this handled? And what about delegates? In dynamic languages I can have almost function-spaghetti and sometimes, its just fine (like hacking UI in javascript). Or do I have to care even about generic delegates?
