  • Not able to delete list which dynamically created with jquery.

    - by shin
    I have two html here. The first one is dynamically generated by php and second one is just html to test. I also have the following jquery. When I click a cross with class delete in the second ones(plain html), it works nicely. However when I click a cross in the first ones, it does not work. It redirect me to the home page with # at the end. I am hoping someone point out what I am doing wrong. Thank in advance. HTML First part (dyanmicall generated) <ul style="display: block;" id="message"> <li class="41"> <span class="user"><strong>shin</strong></span> <span class="msg"> delete this as well</span> <span class="date">2010-01-15 07:47:31</span> <a href="#" id="41" class="delete">x</a> <div class="clear"></div></li> <li class="40"> <span class="user"><strong>shin</strong></span> <span class="msg"> delete me as well</span> <span class="date">2010-01-14 16:01:44</span> <a href="#" id="40" class="delete">x</a> <div class="clear"></div></li> ... ...</ul> Second part which is plain html <ul id="another"> <li><a href="#">you can't delete me</a></li> <li><a href="#" class="delete">delete this</a></li> <li><a href="#" class="delete">delete this</a></li> </ul> Here is jquery $(".delete").click(function(event) { event.preventDefault(); loading.fadeIn(); var commentContainer = $(this).parent(); var id = $(this).attr("id"); // var string = 'id='+ id ; $.ajax({ type: "POST", url: "index.php/admin/messages/changestatus/"+id, // data: string, cache: false, success: function(){ commentContainer.slideUp('slow', function() {$(this).remove();}); loading.fadeOut(); } }); return false; }); I am using CodeIgniter by the way.

  • How do I add a column that displays the number of distinct rows to this query?

    - by Fake Code Monkey Rashid
    Hello good people! I don't know how to ask my question clearly so I'll just show you the money. To start with, here's a sample table: CREATE TABLE sandbox ( id integer NOT NULL, callsign text NOT NULL, this text NOT NULL, that text NOT NULL, "timestamp" timestamp with time zone DEFAULT now() NOT NULL ); CREATE SEQUENCE sandbox_id_seq START WITH 1 INCREMENT BY 1 NO MINVALUE NO MAXVALUE CACHE 1; ALTER SEQUENCE sandbox_id_seq OWNED BY sandbox.id; SELECT pg_catalog.setval('sandbox_id_seq', 14, true); ALTER TABLE sandbox ALTER COLUMN id SET DEFAULT nextval('sandbox_id_seq'::regclass); INSERT INTO sandbox VALUES (1, 'alpha', 'foo', 'qux', '2010-12-29 16:51:09.897579+00'); INSERT INTO sandbox VALUES (2, 'alpha', 'foo', 'qux', '2010-12-29 16:51:36.108867+00'); INSERT INTO sandbox VALUES (3, 'bravo', 'bar', 'quxx', '2010-12-29 16:52:36.370507+00'); INSERT INTO sandbox VALUES (4, 'bravo', 'foo', 'quxx', '2010-12-29 16:52:47.584663+00'); INSERT INTO sandbox VALUES (5, 'charlie', 'foo', 'corge', '2010-12-29 16:53:00.742356+00'); INSERT INTO sandbox VALUES (6, 'delta', 'foo', 'qux', '2010-12-29 16:53:10.884721+00'); INSERT INTO sandbox VALUES (7, 'alpha', 'foo', 'corge', '2010-12-29 16:53:21.242904+00'); INSERT INTO sandbox VALUES (8, 'alpha', 'bar', 'corge', '2010-12-29 16:54:33.318907+00'); INSERT INTO sandbox VALUES (9, 'alpha', 'baz', 'quxx', '2010-12-29 16:54:38.727095+00'); INSERT INTO sandbox VALUES (10, 'alpha', 'bar', 'qux', '2010-12-29 16:54:46.237294+00'); INSERT INTO sandbox VALUES (11, 'alpha', 'baz', 'qux', '2010-12-29 16:54:53.891606+00'); INSERT INTO sandbox VALUES (12, 'alpha', 'baz', 'corge', '2010-12-29 16:55:39.596076+00'); INSERT INTO sandbox VALUES (13, 'alpha', 'baz', 'corge', '2010-12-29 16:55:44.834019+00'); INSERT INTO sandbox VALUES (14, 'alpha', 'foo', 'qux', '2010-12-29 16:55:52.848792+00'); ALTER TABLE ONLY sandbox ADD CONSTRAINT sandbox_pkey PRIMARY KEY (id); Here's the current SQL query I have: SELECT * FROM ( SELECT DISTINCT ON (this, that) id, this, that, timestamp FROM sandbox WHERE callsign = 'alpha' AND CAST(timestamp AS date) = '2010-12-29' ) playground ORDER BY timestamp DESC This is the result it gives me: id this that timestamp ----------------------------------------------------- 14 foo qux 2010-12-29 16:55:52.848792+00 13 baz corge 2010-12-29 16:55:44.834019+00 11 baz qux 2010-12-29 16:54:53.891606+00 10 bar qux 2010-12-29 16:54:46.237294+00 9 baz quxx 2010-12-29 16:54:38.727095+00 8 bar corge 2010-12-29 16:54:33.318907+00 7 foo corge 2010-12-29 16:53:21.242904+00 This is what I want to see: id this that timestamp count ------------------------------------------------------------- 14 foo qux 2010-12-29 16:55:52.848792+00 3 13 baz corge 2010-12-29 16:55:44.834019+00 2 11 baz qux 2010-12-29 16:54:53.891606+00 1 10 bar qux 2010-12-29 16:54:46.237294+00 1 9 baz quxx 2010-12-29 16:54:38.727095+00 1 8 bar corge 2010-12-29 16:54:33.318907+00 1 7 foo corge 2010-12-29 16:53:21.242904+00 1 EDIT: I'm using PostgreSQL 9.0.* (if that helps any).

  • ASP.NET MVC Custom Error Pages with Magical Unicorn

    - by FLClover
    my question is regarding Pure.Kromes answer to this post. I tried implementing my pages' custom error messages using his method, yet there are some problems I can't quite explain. a) When I provoke a 404 Error by entering in invalid URL such as localhost:3001/NonexistantPage, it defaults to the ServerError() Action of my error controller even though it should go to NotFound(). Here is my ErrorController: public class ErrorController : Controller { public ActionResult NotFound() { Response.TrySkipIisCustomErrors = true; Response.StatusCode = (int)HttpStatusCode.NotFound; var viewModel = new ErrorViewModel() { ServerException = Server.GetLastError(), HTTPStatusCode = Response.StatusCode }; return View(viewModel); } public ActionResult ServerError() { Response.TrySkipIisCustomErrors = true; Response.StatusCode = (int)HttpStatusCode.InternalServerError; var viewModel = new ErrorViewModel() { ServerException = Server.GetLastError(), HTTPStatusCode = Response.StatusCode }; return View(viewModel); } } My error routes in Global.asax.cs: routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" }); routes.MapRoute( name: "Error - 404", url: "NotFound", defaults: new { controller = "Error", action = "NotFound" } ); routes.MapRoute( name: "Error - 500", url: "ServerError", defaults: new { controller = "Error", action = "ServerError" } ); And my web.config settings: <system.web> <customErrors mode="On" redirectMode="ResponseRewrite" defaultRedirect="/ServerError"> <error statusCode="404" redirect="/NotFound" /> </customErrors> ... </system.web> <system.webServer> <httpErrors errorMode="Custom" existingResponse="Replace"> <remove statusCode="404" subStatusCode="-1" /> <error statusCode="404" path="/NotFound" responseMode="ExecuteURL" /> <remove statusCode="500" subStatusCode="-1" /> <error statusCode="500" path="/ServerError" responseMode="ExecuteURL" /> </httpErrors> ... The Error views are located in /Views/Error/ as NotFound.cshtml and ServerError.cshtml. b) One funny thing is, When a server error occurs, it does in fact display the Server Error view I defined, however it also outputs a default error message as well saying that the Error page could not be found. Here's how it looks like: Do you have any advice how I could fix these two problems? I really like Pure.Kromes approach to implementing these error messages, but if there are better ways of achieving this don't hestitate to tell me. Thanks! *EDIT : * I can directly navigate to my views through the ErrorController by accessing /Error/NotFound or Error/ServerError. The views themselves only contain some text, no markup or anything. As I said, it actually works in some way, just not the way I intended it to work. There seems to be an issue with the redirect in the web.config, but I haven't been able to figure it out.

  • Impersonation on Windows 2000 to Windows XP Leaves Connections Open

    - by Tallek
    I'm running on a Windows 2000 Pro SP4 box (off domain) and trying to impersonate a local user on a Windows XP box (on domain). I'm using code very similar to the WindowsImpersonationContextFacade in the question posted here: http://stackoverflow.com/questions/879704/how-can-i-temporarily-impersonate-a-user-to-open-a-file. I am using impersonation to remotely start and stop windows services as well as access network shares (for some automated integration tests). To get this working, i had to use LOGON32_PROVIDER_DEFAULT and LOGON32_LOGON_NEW_CREDENTIALS when calling LogonUser. Everything worked beautifully ( Windows XP on domain to Windows XP on domain, Windows XP on domain to Windows Server 2003 off domain, and even Windows XP on domain to Windows 2000 off domain). The one issue was running on Windows 2000 Pro SP4 off the domain and trying to impersonate a local user on a Windows XP box running on the domain. To get the Windows 2000 piece working, i had to use LOGON32_PROVIDER_WINNT50 and LOGON32_LOGON_NEW_CREDENTIALS when calling LogonUser. This seemed to get me 95% of the way there, i could now impersonate the local user on the XP box and start/stop services as well as access a network share using the impersonated credentials. I'm running in to one problem though, calling Undo impersonation and closing the token handle seems to leave the connection to the remote box open. After about 10 or so impersonation calls, further impersonation attempts will fail with an error saying something about too many connections are currently open. If i look at the Computer Management - System Tools - Shared Folders - Sessions on my remote Windows XP box, i can see about 10 sessions open to the Windows 2000 box. I can manually close these (i think they may eventually close themselves, but not very quickly) and then impersonation begins working again few more times. This open session issue doesn't seem to be a problem in any of my other test scenarios, just when running locally on a Windows 2000 box. Any ideas? Edit 1: After some more testing and trying out many different things, this seems to be an issue with open sessions not being reused. On Windows 2000 only, every call to LogonUser to get a token and then using that token to impersonate seems to result in a new session being created. I'm guessing Windows XP & Windows Server 2003 are reusing open sessions since i don't seem to be having any issues with them. If I call LogonUser once, then cache the token, I seem to be able to make as many calls to impersonate as I need using the cached token without running in to the "too many connections" issue. This seems like an ugly work around though since i can't call CloseHandle() on my token every time i perform impersonation. Anybody have any thoughts or ideas, or am i stuck with this ugly hack? Thanks

  • IsAuthenticated is false! weird behaviour + review question

    - by Naor
    This is the login function (after I validate user name and password, I load user data into "user" variable and call Login function: public static void Login(IUser user) { HttpResponse Response = HttpContext.Current.Response; HttpRequest Request = HttpContext.Current.Request; FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, user.UserId.ToString(), DateTime.Now, DateTime.Now.AddHours(12), false, UserResolver.Serialize(user)); HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(ticket)); cookie.Path = FormsAuthentication.FormsCookiePath; Response.Cookies.Add(cookie); string redirectUrl = user.HomePage; Response.Redirect(redirectUrl, true); } UserResolver is the following class: public class UserResolver { public static IUser Current { get { IUser user = null; if (HttpContext.Current.User.Identity.IsAuthenticated) { FormsIdentity id = (FormsIdentity)HttpContext.Current.User.Identity; FormsAuthenticationTicket ticket = id.Ticket; user = Desrialize(ticket.UserData); } return user; } } public static string Serialize(IUser user) { StringBuilder data = new StringBuilder(); StringWriter w = new StringWriter(data); string type = user.GetType().ToString(); //w.Write(type.Length); w.WriteLine(user.GetType().ToString()); StringBuilder userData = new StringBuilder(); XmlSerializer serializer = new XmlSerializer(user.GetType()); serializer.Serialize(new StringWriter(userData), user); w.Write(userData.ToString()); w.Close(); return data.ToString(); } public static IUser Desrialize(string data) { StringReader r = new StringReader(data); string typeStr = r.ReadLine(); Type type=Type.GetType(typeStr); string userData = r.ReadToEnd(); XmlSerializer serializer = new XmlSerializer(type); return (IUser)serializer.Deserialize(new StringReader(userData)); } } And the global.asax implements the following: void Application_PostAuthenticateRequest(Object sender, EventArgs e) { IPrincipal p = HttpContext.Current.User; if (p.Identity.IsAuthenticated) { IUser user = UserResolver.Current; Role[] roles = user.GetUserRoles(); HttpContext.Current.User = Thread.CurrentPrincipal = new GenericPrincipal(p.Identity, Role.ToString(roles)); } } First question: Am I do it right? Second question - weird thing! The user variable I pass to Login has 4 members: UserName, Password, Name, Id. When UserResolver.Current executed, I got the user instance. I descided to change the user structure - I add an array of Warehouse object. Since that time, when UserResolver.Current executed (after Login), HttpContext.Current.User.Identity.IsAuthenticated was false and I couldn't get the user data. When I removed the Warehouse[] from user structure, it starts to be ok again and HttpContext.Current.User.Identity.IsAuthenticated become true after I Login. What is the reason to this weird behaviour?

  • A continued saga of C# interoprability with unmanaged C++

    - by Gilad
    After a day of banging my head against the wall both literally and metaphorically, I plead for help: I have an unmanaged C++ project, which is compiled as a DLL. Let's call it CPP Project. It currently works in an unmanaged environment. In addition, I have created a WPF project, that shall be called WPF Project. This project is a simple and currently almost empty project. It contains a single window and I want it to use code from Project 1. For that, I have created a CLR C++ project, which shall be called Interop Project and is also compiled as a DLL. For simplicity I will attach some basic testing code I have boiled down to the basics. CPP Project has the following two testing files: tester.h #pragma once extern "C" class __declspec(dllexport) NativeTester { public: void NativeTest(); }; tester.cpp #include "tester.h" void NativeTester::NativeTest() { int i = 0; } Interop Project has the following file: InteropLib.h #pragma once #include <tester.h> using namespace System; namespace InteropLib { public ref class InteropProject { public: static void Test() { NativeTester nativeTester; nativeTester.NativeTest(); } }; } Lastly, WPF Project has a single window refrencing Interop Project: MainWindow.xaml.cs using System; using System.Windows; using InteropLib; namespace AppGUI { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); InteropProject.Test(); } } } And the XAML itself has an empty window (default created). Once I am trying to run the WPF project, I get the following error: System.Windows.Markup.XamlParseException: 'The invocation of the constructor on type 'AppGUI.MainWindow' that matches the specified binding constraints threw an exception.' Line number '3' and line position '9'. --- System.IO.FileNotFoundException: Could not load file or assembly 'InteropLib.dll' or one of its dependencies. The specified module could not be found. at AppGUI.MainWindow..ctor() Interestingly enough, if I do not export the class from CPP Project, I do not get this error. Say, if i change tester.h to: #pragma once class NativeTester { public: void NativeTest() { int i = 0; } }; However, in this case I cannot use my more complex classes. If I move my implementation to a cpp file like before, I get unresolved linkage errors due to my not exporting my code. The C++ code I want to actually use is large and has many classes and is object oriented, so I can't just move all my implementation to the h files. Please help me understand this horrific error I've been trying resolve without success. Thanks.

  • How do I create a list or set object in a class in Python?

    - by Az
    For my project, the role of the Lecturer (defined as a class) is to offer projects to students. Project itself is also a class. I have some global dictionaries, keyed by the unique numeric id's for lecturers and projects that map to objects. Thus for the "lecturers" dictionary (currently): lecturer[id] = Lecturer(lec_name, lec_id, max_students) I'm currently reading in a white-space delimited text file that has been generated from a database. I have no direct access to the database so I haven't much say on how the file is formatted. Here's a fictionalised snippet that shows how the text file is structured. Please pardon the cheesiness. 0001 001 "Miyamoto, S." "Even Newer Super Mario Bros" 0002 001 "Miyamoto, S." "Legend of Zelda: Skies of Hyrule" 0003 002 "Molyneux, P." "Project Milo" 0004 002 "Molyneux, P." "Fable III" 0005 003 "Blow, J." "Ponytail" The structure of each line is basically proj_id, lec_id, lec_name, proj_name. Now, I'm currently reading the relevant data into the relevant objects. Thus, proj_id is stored in class Project whereas lec_name is a class Lecturer object, et al. The Lecturer and Project classes are not currently related. However, as I read in each line from the text file, for that line, I wish to read in the project offered by the lecturer into the Lecturer class; I'm already reading the proj_id into the Project class. I'd like to create an object in Lecturer called offered_proj which should be a set or list of the projects offered by that lecturer. Thus whenever, for a line, I read in a new project under the same lec_id, offered_proj will be updated with that project. If I wanted to get display a list of projects offered by a lecturer I'd ideally just want to use print lecturers[lec_id].offered_proj. My Python isn't great and I'd appreciate it if someone could show me a way to do that. I'm not sure if it's better as a set or a list, as well. Update After the advice from Alex Martelli and Oddthinking I went back and made some changes and tried to print the results. Here's the code snippet: for line in csv_file: proj_id = int(line[0]) lec_id = int(line[1]) lec_name = line[2] proj_name = line[3] projects[proj_id] = Project(proj_id, proj_name) lecturers[lec_id] = Lecturer(lec_id, lec_name) if lec_id in lecturers.keys(): lecturers[lec_id].offered_proj.add(proj_id) print lec_id, lecturers[lec_id].offered_proj The print lecturers[lec_id].offered_proj line prints the following output: 001 set([0001]) 001 set([0002]) 002 set([0003]) 002 set([0004]) 003 set([0005]) It basically feels like the set is being over-written or somesuch. So if I try to print for a specific lecturer print lec_id, lecturers[001].offered_proj all I get is the last the proj_id that has been read in.

  • How do I print out objects in an array in python?

    - by Jonathan
    I'm writing a code which performs a k-means clustering on a set of data. I'm actually using the code from a book called collective intelligence by O'Reilly.

  • Qt vs .NET - a few comparisons [closed]

    - by Pirate for Profit
    Event Handling In Qt the event handling system you just emit signals when something cool happens and then catch them in slots, for instance emit valueChanged(int percent, bool something); and void MyCatcherObj::valueChanged(int p, bool ok){} blocking them and disconnecting them when needed, doing it across threads... once you get the hang of it, it just seems a lot more natural and intuitive than the way the .NET event handling is set up (you know, object sender, CustomEventArgs e). And I'm not just talking about syntax, because in the end the .NET delegate crap is the bomb. I'm also talking about in more than just reflection (because, yes, .NET obviously has much stronger reflection capabilities). I'm talking about in the way the system feels to a human being. Qt wins hands down i m o. Basically, the footprints make more sense and you can visualize the project easier without the clunky event handling system. I wish I could it explain it better. The only thing is, I do love some of the ease of C# compared to C++ and .NET's assembly architecture. That is a big bonus for modular projects, which are a PITA to do in C++. Database Ease of Doing Crap Also what about datasets and database manipulations. I think .net wins here but I'm not sure. Threading/Conccurency How do you guys think of the threading? In .NET, all I've ever done is make like a list of master worker threads with locks. I like QConcurrentFramework, you don't worry about locks or anything, and with the ease of the signal slot system across threads it's nice to get notified about the progress of things. Memory Usage Also what do you think of the overall memory usage comparison. Is the .NET garbage collector pretty on the ball and quick compared to the instantaneous nature of native memory management? Or does it just let programs leak up a storm and lag the computer then clean it up when it's about to really lag? However, I am a n00b who doesn't know what I'm talking about, please school me on the subject.

  • How to set a key binding to make Emacs as transparent/opaque as I want?

    - by Vivi
    I want to have a command in Emacs to make it as opaque/transparent as I want (refer to the fabulous question that pointed out that transparency is possible in Emacs, and the EmacsWiki page linked there which has the code I am using below). The EmacsWiki code sets "C-c t" to toggle the previously set transparency on and off: ;;(set-frame-parameter (selected-frame) 'alpha '(<active> [<inactive>])) (set-frame-parameter (selected-frame) 'alpha '(85 50)) (add-to-list 'default-frame-alist '(alpha 85 50)) enter code here(eval-when-compile (require 'cl)) (defun toggle-transparency () (interactive) (if (/= (cadr (find 'alpha (frame-parameters nil) :key #'car)) 100) (set-frame-parameter nil 'alpha '(100 100)) (set-frame-parameter nil 'alpha '(85 60)))) (global-set-key (kbd "C-c t") 'toggle-transparency) What I would like to do is to be able to choose the % transparency when I am in Emacs. If possible, I would like a command where I type for example "C-c t N" (where N is the % opaqueness) for the active frame, and then "M-c t N" for the inactive window. If that can't be done like that, then maybe a command where if I type "C-c t" it asks me for the number which gives the opaqueness of the active window (and the same for the inactive window using "M-c t"). Thanks in advance for your time :) Below are just some comments that are not important to answer the question if you are not interested: I really want this because when I told my supervisor I was learning Emacs he said TexShop is much better and that I am using software from the 80's. I told him about the wonders of Emacs and he said TexShop has all of it and more. I matched everything he showed me except for the transparency (though he couldn't match the preview inside Emacs from preview-latex). I found the transparency thing by chance, and now I want to show him Emacs rules! I imagine this will be a piece of cake for some of you, and even though I could get it done if I spent enough time trying to learn lisp or reading around, I am not a programmer and I have only been using Emacs and a mac for a week. I am lost already as it is! So thanks in advance for your time and help - I will learn lisp eventually!

  • Reading Metadata property of GifBitmapDecoder...why is it null?

    - by David
    How can I read the delay, left and top offset data for each frame of a gif? I've gotten this far. Load the Gif var myGif = new GifBitmapDecoder(uri, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.OnLoad); Get a frame var frame = myGif.Frames[i]; From MSDN: Native Image Format Metadata Queries read (ushort)Metadata.GetQuery("/grctlext/Delay"), (ushort)Metadata.GetQuery("/imgdesc/Left"), (ushort)Metadata.GetQuery("/imgdesc/Top") But two things don't work. First the Metadata property of both the gif and the frame are always null, even if I try different animated gif files. Second, the Metadata property of the frame doesn't seem to have a GetQuery method. How do I run these queries, what did I miss? Edit: Here is sample code that gives me null metadata. Using a fresh install of VS2010 Premium, on a fresh WPF application. The image file is the one in the comments. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; namespace WpfApplication1 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); var uri = new Uri(@"c:\b-414328-animated_gif_.gif"); var myGif = new GifBitmapDecoder(uri, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.OnLoad); var frame = myGif.Frames[0]; Title = ""; Title += "Global Metadata is null: " + (myGif.Metadata == null).ToString(); Title += "; Frame Metadata is null: " + (frame.Metadata == null).ToString(); // Crash due to null metadata //var frameData = (BitmapMetadata)frame.Metadata; //var rate = (ushort)frameData.GetQuery("/grctlext/Delay"); } } }

  • Event sourcing: Write event before or after updating the model

    - by Magnus
    I'm reasoning about event sourcing and often I arrive at a chicken and egg problem. Would be grateful for some hints on how to reason around this. If I execute all I/O-bound processing async (ie writing to the event log) then how do I handle, or sometimes even detect, failures? I'm using Akka Actors so processing is sequential for each event/message. I do not have any database at this time, instead I would persist all the events in an event log and then keep an aggregated state of all the events in a model stored in memory. Queries are all against this model, you can consider it to be a cache. Example Creating a new user: Validate that the user does not exist in model Persist event to journal Update model (in memory) If step 3 breaks I still have persisted my event so I can replay it at a later date. If step 2 breaks I can handle that as well gracefully. This is fine, but since step 2 is I/O-bound I figured that I should do I/O in a separate actor to free up the first actor for queries: Updating a user while allowing queries (A0 = Front end/GUI actor, A1 = Processor Actor, A2 = IO-actor, E = event bus). (A0-E-A1) Event is published to update user 'U1'. Validate that the user 'U1' exists in model (A1-A2) Persist event to journal (separate actor) (A0-E-A1-A0) Query for user 'U1' profile (A2-A1) Event is now persisted continue to update model (A0-E-A1-A0) Query for user 'U1' profile (now returns fresh data) This is appealing since queries can be processed while I/O-is churning along at it's own pace. But now I can cause myself all kinds of problems where I could have two incompatible commands (delete and then update) be persisted to the event log and crash on me when replayed up at a later date, since I do the validation before persisting the event and then update the model. My aim is to have a simple reasoning around my model (since Actor processes messages sequentially single threaded) but not be waiting for I/O-bound updates when Querying. I get the feeling I'm modeling a database which in itself is might be a problem. If things are unclear please write a comment.

  • Problem to generate nested ul lists using PHP

    - by Michael Mao
    Hi all: I am working on a front-end web app where a nested unordered list would be used for the jQuery plugin mcdropdown. Here is the data structure from PHP: a nested array of arrays : Array ( [0] => Array ( [fullpath] => ../foil/alphanumeric/ [depth] => 0 ) [1] => Array ( [fullpath] => ../foil/alphanumeric/letters/ [depth] => 1 ) [2] => Array ( [fullpath] => ../foil/alphanumeric/numbers/ [depth] => 1 ) [3] => Array ( [fullpath] => ../foil/alphanumeric/numbers/symbols/ [depth] => 2 ) ) Basically, I took the excellent answer from this question on SO, modified it a bit : global $fullpaths; // $fullpaths contains the above data structure in print_r $result = ''; $currentDepth = -1; while(!empty($fullpaths)) { $currentNode = array_shift($fullpaths); if($currentNode['depth'] > $currentDepth) { $result .='<ul>'; } if($currentNode['depth'] < $currentDepth) { $result .=str_repeat('</ul>', $currentDepth - $currentNode['depth']); } $result .= '<li>'. $currentNode['fullpath'] .'</li>'; $currentDepth = $currentNode['depth']; if(empty($fullpaths)) { $result .= str_repeat('</ul>', 1 + $currentDepth); } } print $result; and got the following output: <ul> <li>../foil/alphanumeric/</li> <ul> <li>../foil/alphanumeric/letters/</li> <li>../foil/alphanumeric/numbers/</li> <ul> <li>../foil/alphanumeric/numbers/symbols/</li> </ul> </ul> </ul> Which cannot be accepted by the mcdropdown jQuery plugin, it expects something like this: <li rel="1"> 'Alphanumeric' <ul> <li rel="2">'Letters'</li> <li rel="3">'Numbers' <ul> <li rel="4">'Symbols'</li> </ul> </li> </ul> </li> To be frank, I don't quite understand how the answer from that question works, I have been trying to modify that solution to cope with my situation, but still failed. Any help and suggestion is much appropriated in advance.

  • How can I make my Perl Jabber bot an event-driven program?

    - by TheGNUGuy
    I'm trying to make a Jabber bot and I am having trouble keeping it running while waiting for messages. How do I get my script to continuously run? I have tried calling a subroutine that has a while loop that I, in theory, have set up to check for any messages and react accordingly but my script isn't behaving that way. Here is my source: http://pastebin.com/03Habbvh # set jabber bot callbacks $jabberBot-SetMessageCallBacks(chat=\&chat); $jabberBot-SetPresenceCallBacks(available=\&welcome,unavailable=\&killBot); $jabberBot-SetCallBacks(receive=\&prnt,iq=\&gotIQ); $jabberBot-PresenceSend(type="available"); $jabberBot-Process(1); sub welcome { print "Welcome!\n"; $jabberBot-MessageSend(to=$jbrBoss-GetJID(),subject="",body="Hello There!",type="chat",priority=10); &keepItGoing; } sub prnt { print $_[1]."\n"; } #$jabberBot-MessageSend(to=$jbrBoss-GetJID(),subject="",body="Hello There!

  • How do I integrate a new MVC C# Project with an existing Web Forms VB.NET Web Application Project?

    - by Jordan Rieger
    We have a corporate website with a large amount of dynamic business application pages (e.g. Shopping Cart, Helpdesk, Product/Service management, Reporting, etc.) The site was built as an ASP.Net Web Application Project (WAP). Our systems have evolved over the years to use .NET 4.5 and various custom business logic DLLs (written in a mix of C# and VB.NET). However, the site itself is still using VB.NET Web Forms. We now have done a few side projects in MVC 4 using Razor/C#, and we want to use this framework for new pages on the main corporate site going forward. What would be the easiest way to achieve this? I found this nice list of steps to integrate MVC 4 into an existing Web Forms app. The problem is that because our existing app is a VB.NET WAP, it compiles into a single DLL, and .NET allows only one language per DLL. The site is way too big for us to contemplate converting it to C# all at once (yes, I've looked at the conversion tools, and they're good, but even 99% accuracy would leave us a huge amount of cleanup work.) I thought about converting the existing WAP into a Web Site Project (WSP) which does allow mixing languages and then following the steps above, but after a few pages of Google results, I couldn't find any steps for converting a WAP to WSP. (Plenty of sites offer the reverse steps: converting a WSP to a WAP.) Another idea I had was to create a completely separate MVC project, and then somehow squish them together into the same folder structure, where they would share the bin folder but compile to separate DLL's. I have no idea if this is possible, because certain files would collide (e.g. Global.asax, web.config, etc.) Finally, I can imagine a compromise solution where we keep all the MVC stuff in its own separate application under a subfolder of the main solution. We already use our own custom session state solution, so it wouldn't be difficult to pass data between the old site to the new pages. Which of the ideas above do you think makes the most sense for us? Is there another solution that I'm missing?

  • AD-DirectoryServices: .NET2.0 - Speaking architecture, approach and best practices... Suggestions?

    - by Will Marcouiller
    I've been mandated to write an application to migrate the Active Directory access models to another environment. Here's the context: I'm stuck with VB.NET 2005 and .NET Framework 2.0; The application must use the Windows authenticated user to manage AD; The objects I have to handle are Groups, Users and OrganizationalUnits; I intend to use the Façade design pattern to provider ease of use and a fully reusable code; I plan to write a factory for each of the objects managed (group, ou, user); The use of Attributes should be useful here, I guess; As everything is about the DirectoryEntry class when accessing the AD, it seems a good candidate for generic types. Obligatory features: User creates new OUs manually; User creates new group manually; User creates new user (these users are services accounts) manually; Application reads an XML file which contains the OUs, groups and users to create; Application informs the user about the OUs, groups and users that shall be created; User specifies the domain environment where to migrate the XML input file designated objects; User makes changes if needed, and launches the task operations; Application performs required by the XML input file operations against the underlying AD as specified by the user; Application informs the user upon completion. Linear features: User fetches OUs, groups, users; User changes OUs, groups, users; User deletes OUs, groups, users; The application logs AD entries and operations performed, plus errors and exceptions; Nice-to-have features: Application rollbacks operations on error or exception. I've been working for weeks now to get acquainted with the AD and the System.DirectoryServices assembly. But I don't seem to find a way to be fully satisfied with what I'm doing and always looking for better. I have studied Bret de Smet's Linq to AD on CodePlex, but then again, I can't use it as I'm stuck with .NET 2.0, so no Linq! But I've learned about Attributes, and seen that he's working with generic types as he codes a DirectorySource class to perform the operations for OUs, groups and users. I have been able to add groups to the AD; I have been able to add users to the AD; The created user is automatically disabled? I seem to get confused with the use of a LDAP path to add objects. For instance, one needs two instances of a System.DirectoryServices.DirectoryEntry class to add a group, for instance. Why this? Any suggestions? Thanks for any help, code sample, ideas, architural solution, everything!

  • Binding functions of derived class with luabind

    - by Anamon
    I am currently developing a plugin-based system in C++ which provides a Lua scripting interface, for which I chose to use luabind. I'm using Lua 5 and luabind 0.9, both statically linked and compiled with MSVC++ 8. I am now having trouble binding functions with luabind when they are defined in a derived class, but not its parent class. More specifically, I have an abstract base class called 'IPlugin' from which all plugin classes inherit. When the plugin manager initialises, it registers that class and its functions like this: luabind::open(L); luabind::module(L) [ luabind::class_("IPlugin") .def("start", (void(IPlugin::*)())&IPlugin::start) ]; As it is only known at runtime what effective plugin classes are available, I had to solve loading plugins in a kind of roundabout way. The plugin manager exposes a factory function to Lua, which takes the name of a plugin class and a desired object name. The factory then creates the object, registers the plugin's class as inheriting from the 'IPlugin' base class, and immediately calls a function on the created object that registers itself as a global with the Lua state, like this: void PluginExample::registerLuaObject(lua_State *L, string a_name) { luabind::globals(L)[a_name] = (PluginExample*)this; } I initially did this because I had problems with Lua determining the most derived class of the object, as if I register it from the StreamManager it is only known as a subtype of 'IPlugin' and not the specific subtype. I'm not sure anymore if this is even necessary though, but it works and the created object is subsequently accessible from Lua under 'a_name'. The problem I have, though, is that functions defined in the derived class, which were not declared at all in the parent class, cannot be used. Virtual functions defined in the base class, such as 'start' above, work fine, and calling them from Lua on the new object runs the respective redefined code from the 'PluginExample' class. But if I add a new function to 'PluginExample', here for example a function taking no arguments and returning void, and register it like this: luabind::module(L) [ luabind::class_("PluginExample") .def(luabind::constructor()) .def("func", &PluginExample::func) ]; calling 'func' on the new object yields the following Lua runtime error: No matching overload found, candidates: void func(PluginExample&) I am correctly using the ':' syntax so the 'self' argument is not needed and it seems suddenly Lua cannot determine the derived type of the object anymore. I am sure I am doing something wrong, probably having to do with the two-step binding required by my system architecture, but I can't figure out where. I'd much appreciate some help =)

  • What is a good platform for building a game framework targetting both web and native languages?

    - by fuzzyTew
    I would like to develop (or find, if one is already in development) a framework with support for accelerated graphics and sound built on a system flexible enough to compile to the following: native ppc/x86/x86_64/arm binaries or a language which compiles to them javascript actionscript bytecode or a language which compiles to it (actionscript 3, haxe) optionally java I imagine, for example, creating an API where I can open windows and make OpenGL-like calls and the framework maps this in a relatively efficient manner to either WebGL with a canvas object, 3d graphics in Flash, OpenGL ES 2 with EGL, or desktop OpenGL in an X11, Windows, or Cocoa window. I have so far looked into these avenues: Building the game library in haXe Pros: Targets exist for php, javascript, actionscript bytecode, c++ High level, object oriented language Cons: No support for finally{} blocks or destructors, making resource cleanup difficult C++ target does not allow room for producing highly optimized libraries -- the foreign function interface requires all primitive types be boxed in a wrapper object, as if writing bindings for a scripting language; these feel unideal for real-time graphics and audio, especially exporting low-level functions. Doesn't seem quite yet mature Using the C preprocessor to create a translator, writing programs entirely with macros Pros: CPP is widespread and simple to use Cons: This is an arduous task and probably the wrong tool for the job CPP implementations differ widely in support for features (e.g. xcode cpp has no variadic macros despite claiming C99 compliance) There is little-to-no room for optimization in this route Using llvm's support for multiple backends to target c/c++ to web languages Pros: Can code in c/c++ LLVM is a very mature highly optimizing compiler performing e.g. global inlining Targets exist for actionscript (alchemy) and javascript (emscripten) Cons: Actionscript target is closed source, unmaintained, and buggy. Javascript targets do not use features of HTML5 for appropriate optimization (e.g. linear memory with typed arrays) and are immature An LLVM target must convert from low-level bytecode, so high-level constructs are lost and bloated unreadable code is created from translating individual instructions, which may be more difficult for an unprepared JIT to optimize. "jump" instructions cause problems for languages with no "goto" statements. Using libclang to write a translator from C/C++ to web languages Pros: A beautiful parsing library providing easy access to the code structure Can code in C/C++ Has sponsored developer effort from Apple Cons: Incomplete; current feature set targets IDEs. Basic operators are unexposed and must be manually parsed from the returned AST element to be identified. Translating code prior to compilation may forgo optimizations assumed in c/c++ such as inlining. Creating new code generators for clang to translate into web languages Pros: Can code in C/C++ as libclang Cons: There is no API; code structure is unstable A much larger job than using libclang; the innards of clang are complex Building the game library in Common Lisp Pros: Flexible, ancient, well-developed language Extensive introspection should ease writing translators Translators exist for at least javascript Cons: Unfamiliar language No standardized library functions, widely varying implementations Which of these avenues should I pursue? Do you know of any others, or any systems that might be useful? Does a general project like this exist somewhere already? Thank you for any input.

  • How to solve Python memory leak when using urrlib2?

    - by b_m
    Hi, I'm trying to write a simple Python script for my mobile phone to periodically load a web page using urrlib2. In fact I don't really care about the server response, I'd only like to pass some values in the URL to the PHP. The problem is that Python for S60 uses the old 2.5.4 Python core, which seems to have a memory leak in the urrlib2 module. As I read there's seems to be such problems in every type of network communications as well. This bug have been reported here a couple of years ago, while some workarounds were posted as well. I've tried everything I could find on that page, and with the help of Google, but my phone still runs out of memory after ~70 page loads. Strangely the Garbege Collector does not seem to make any difference either, except making my script much slower. It is said that, that the newer (3.1) core solves this issue, but unfortunately I can't wait a year (or more) for the S60 port to come. here's how my script looks after adding every little trick I've found: import urrlib2, httplib, gc while(true): url = "http://something.com/foo.php?parameter=" + value f = urllib2.urlopen(url) f.read(1) f.fp._sock.recv=None # hacky avoidance f.close() del f gc.collect() Any suggestions, how to make it work forever without getting the "cannot allocate memory" error? Thanks for advance, cheers, b_m update: I've managed to connect 92 times before it ran out of memory, but It's still not good enough. update2: Tried the socket method as suggested earlier, this is the second best (wrong) solution so far: class UpdateSocketThread(threading.Thread): def run(self): global data while 1: url = "/foo.php?parameter=%d"%data s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(('something.com', 80)) s.send('GET '+url+' HTTP/1.0\r\n\r\n') s.close() sleep(1) I tried the little tricks, from above too. The thread closes after ~50 uploads (the phone has 50MB of memory left, obviously the Python shell has not.) UPDATE: I think I'm getting closer to the solution! I tried sending multiple data without closing and reopening the socket. This may be the key since this method will only leave one open file descriptor. The problem is: import socket s=socket.socket(socket.AF_INET, socket.SOCK_STREAM) socket.connect(("something.com", 80)) socket.send("test") #returns 4 (sent bytes, which is cool) socket.send("test") #4 socket.send("test") #4 socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns the number of sent bytes, ok socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns 0 on the phone, error on Windows7* socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns 0 on the phone, error on Windows7* socket.send("test") #returns 0, strange... *: error message: 10053, software caused connection abort Why can't I send multiple messages??

  • Wrong sessionID being used in callback, but only on one particular computer

    - by user210119
    I am writing a Python/Django web application that uses OAuth (for the TwitterAPI, not that it should matter). I am storing a session ID in my login function, and then after using OAuth to get the user's token, I try to retrieve the sessionID in my callback function. The callback function then always fails(throws an exception) because it can't find the OAuth token in the session. Through the debugger, I am able to determine that the session ID that the server is using is incorrect - it does not match the session ID that was stored in the login function. It's therefore unsurprising that the Oauth tokens were not there. The session that appears in the callback was the same one each time (until I tried deleting it - see "things I've tried below"), and it started out as an old session, with some data in it that is from a different django app running on the same server that I hadn't touched in a couple weeks. Here's the kicker: everything I described is an issue only on our production server, and only when connecting to it from my computer. Let me clarify: this only happens with my particular laptop. I can connect to the app just fine from someone else's computer. Other people cannot connect with their accounts on my computer. Furthmore, I can connect just fine to the app when it is running on my localhost using the built-in django webserver, just not to the production server. My setup: my server and local box are running= Django 1.2.0 and Python 2.6.5. My local box is running Snow Leopard and the Django webserver, the server is running Ubuntu, Apache2, and mod-wsgi. For sessions, I am using Django's default session backend (DB). Things I have tried, all to no avail: logging in with a different account, including new accounts that have never OAuthed to this app before Clearing cookies, using incognito mode, using a different web browser on my same computer. Each time, upon inspecting my cookies, the sessionID matched the sessionID in the login function and was different from the sessionID in the callback. deleting the session in the database that appears in the callback function, (the one that appeared to be old data). The callback function still fails, and the sessionID it appears to be using is now a new one using a different session backend (DB-cache, flat file, etc...) restarting the server, my computer, etc. My first question on StackOverflow, so bear with me if I didn't quite follow local conventions. I am just at a loss as to what to even look for - what are the things that could possibly be causing sessions to not work on my particular computer, and (so far!) only my particular computer?

  • Feeding PDF through IInternetSession to WebBrowser control - Error

    As related to my previous question, I have developed a temporary asynchronous pluggable protocol with the specific aim to be able to serve PDF documents directly to a WebBrowser control via a database. I need to do this because my limitations include not being able to access the disk other than IsolatedStorage; and a MemoryStream would be far better for serving up PDF documents that average around 31kb. Unfortunately the code doesn't work, and I'm getting an error from the WebBrowser control (i.e. IE): Unable to download . Unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. The line in my code where this occurs is within the following: pOIProtSink.ReportData(BSCF.BSCF_LASTDATANOTIFICATION, (uint)_stream.Length, (uint)_stream.Length); However, if you download the project and run it, you will be able to see the stream is successfully read and passed to the browser, so it seems like there's a problem somewhere to do with the end of reading the data: public uint Read(IntPtr pv, uint cb, out uint pcbRead) { var bytesToRead = Math.Min(cb, _streamBuffer.Length); pcbRead = (uint)_stream.Read(_streamBuffer, 0, (int)bytesToRead); Marshal.Copy(_streamBuffer, 0, pv, (int)pcbRead); return (pcbRead == 0 || pcbRead < cb) ? HRESULT.S_FALSE : HRESULT.S_OK; } Here is the entire sample project: InternetSessionSample.zip (VS2010) I will leave this up for as long as I can to help other people in the future If anyone has any ideas why I might be getting this message and can shed some light on the problem, I would be grateful for the assistance. EDIT: A friend suggested inserting a line that calls the IInternetProtocolSink.ReportProgress with BINDSTATUS_CACHEFILENAMEAVAILABLE pointing at the original file. This prevents it from failing now and shows the PDF in the Adobe Reader control, but means it defeats the purpose of this by having Adobe Reader simply load from the cache file (which I can't provide). See below: pOIProtSink.ReportProgress(BINDSTATUS.BINDSTATUS_CACHEFILENAMEAVAILABLE, @"D:\Visual Studio Solutions\Projects\InternetSessionSample\bin\Debug\sample.pdf"); pOIProtSink.ReportData(BSCF.BSCF_LASTDATANOTIFICATION, (uint)_stream.Length, (uint)_stream.Length); This is progress though, I guess.

  • navigator.onLine

    - by cf_PhillipSenn
    I'm playing with the incomplete example found at http://www.w3.org/TR/offline-webapps/ But I'm distressed to see comments in it like: "renders the note somewhere", and "report error", and "// …" So, will someone please help me write a valid example? Here's what I've got so far: <!DOCTYPE HTML> <html manifest="cache-manifest"> <head> <script> var db = openDatabase("notes", "", "The Example Notes App!", 1048576); function renderNote(row) { // renders the note somewhere } function reportError(source, message) { // report error } function renderNotes() { db.transaction(function(tx) { tx.executeSql('CREATE TABLE IF NOT EXISTS Notes(title TEXT, body TEXT)', []); tx.executeSql(‘SELECT * FROM Notes’, [], function(tx, rs) { for(var i = 0; i < rs.rows.length; i++) { renderNote(rs.rows[i]); } }); }); } function insertNote(title, text) { db.transaction(function(tx) { tx.executeSql('INSERT INTO Notes VALUES(?, ?)', [ title, text ], function(tx, rs) { // … }, function(tx, error) { reportError('sql', error.message); }); }); } </script> <style> label { display:block; } </style> </head> <body> <form> <label for="mytitle">Title:</label> <input name="mytitle"> <label for="mytext">Text:</label> <textarea name="mytext"></textarea> <!-- There is no submit button because I want to save the info on every keystroke --> </form> </body> </html> I also know that I have to incorporate this in there somewhere: if (navigator.onLine) { // Send data using XMLHttpRequest } else { // Queue data locally to send later } But I'm not sure what even I would tie that too.

  • Display all images from outside web root folder using PHP

    - by micmola
    Hello, I want to display all images that are stored outside my web root folder. Please help me. I am only able to display one image repeatedly. For example, if I have 5 images in my folder, only one image is displayed on my browser 5 times. Please help me on this. I've been working on this problem for over a month now. I'm a newbie. Help. Thank you. Here is the code I'm using. images.php <?php // Get our database connector require("includes/copta.php"); // Grab the data from our people table $sql = "select * from people"; $result = mysql_query($sql) or die ("Could not access DB: " . mysql_error()); $imgLocation = " /uploadfile/"; while ($row = mysql_fetch_array($result)) { $imgName = $row["filename"]; $imgPath = $imgLocation . $imgName; echo "<img src=\"call_images.php?imgPath=" . $imgName . "\" alt=\"\"><br/>"; echo $row['id'] . " " . $imgName. "<br />"; } ?> call_images.php <?php // Get our database connector require("includes/copta.php"); $imgLocation = '/ uploadz/'; $sql = "select * from people"; $result = mysql_query($sql) or die ("Could not access DB: " . mysql_error()); while ($row = mysql_fetch_array($result)) { $imgName = $row["filename"]; $imgPath = $imgLocation . $imgName; // Make sure the file exists if(!file_exists($imgPath) || !is_file($imgPath)) { header('HTTP/1.0 404 Not Found'); die('The file does not exist'); } // Make sure the file is an image $imgData = getimagesize($imgPath); if(!$imgData) { header('HTTP/1.0 403 Forbidden'); die('The file you requested is not an image.'); } // Set the appropriate content-type // and provide the content-length. header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Type: image/jpg"); header("Content-length: " . filesize($imgPath)); // Print the image data readfile($imgPath); exit(); } ?>
