  • YUI button onclick get value

    - by Simon
    I have a a set of yui buttons generated using the standard yui html. <span class="yui-button yui-checkbox-button" id="analystbutton1"> <span class="first-child"> <button type="button" class="facetbutton" tabindex="0" id="analystbutton1-button"> Joe Bloggs </button> </span> </span> I create the buttons like so, and I then have some javascript to create the button and the listener. var analystCButton1 = new YAHOO.widget.Button("analystbutton1", { type:"checkbox", value:"BLOGGS", checked:false }); analystCButton1.on("click", onFacetClick); Finally I have the onFacetClick function var onFacetClick = function (e) { // e is the event var target = YAHOO.util.Event.getTarget(e); var button = new YAHOO.widget.Button(target); alert(button.get('type')); alert(button.get('id')); alert(button.get('value')); }; When I click on any of my buttons the first two alerts display the type and id (although not what I would expect). I cannot get the value, the alert doesn't fire, but I see no error in FireBug or the error console. alert(button.get('type')); returns push - I would expect checkbox alert(button.get('id')); returns analystbutton1-button

  • Send post request from client to node.js

    - by Husar
    In order to learn node.js I have built a very simple guestbook app. There is basically just a comment form and a list of previous comments. Currently the app is client side only and the items are stored within local storage. What I want to do is send the items to node where I will save them using Mongo DB. The problem is I have not yet found a way to establish a connection to send data back and forth the client and node.js using POST requests. What I do now is add listeners to the request and wait for data I send: request.addListener('data', function(chunk) { console.log("Received POST data chunk '"+ chunk + "'."); }); On the client side I send the data using a simple AJAX request: $.ajax({ url: '/', type: 'post', dataType: 'json', data: 'test' }) This does not work at all in them moment. It could be that I don't know what url to place in the AJAX request 'url' parameter. Or the whole thing might just be the build using the wrong approach. I have also tried implementing the method described here, but also with no success. It would really help if anyone can share some tips on how to make this work (sending POST request from the client side to node and back) or share any good tutorials. thanks.

  • Mimic.js handle fault response

    - by nikolas
    i use mimic.js regarding a project that i m developing.. the issue that i face, is if there is a fault response from the webservice, mimic, doesn't handle it, and the browser remains "awaiting" for a response, that has actually been back, but hasn't been handled by mimic.. to be more specific, one typical fault response is the following.. <?xml version="1.0" encoding="UTF-8"?> <methodResponse> <fault> <value> <struct> <member> <name>faultCode</name><value><int>104</int></value> </member> <member> <name>faultString</name><value><string>Invalid Input Parameters</string></value> </member> </struct></value></fault></methodResponse> and chrome console get me the error mimic.js:11 Uncaught TypeError: Cannot read property 'childNodes' of null any suggestions on how to handle "fault" responses? mimic.js hasn't been altered at all.. also tried to bypass the fact that mimic can't handle the fault, by trying to use the isFault flag, in the if statement, with no success either.. isFault is supposed to get a boolean value, i guess true/false?

  • MS Query Analyzer / Management Studio replacement?

    - by kprobst
    I've been using SQL Server since version 6.5 and I've always been a bit amazed at the fact that the tools seem to be targeted to DBAs rather than developers. I liked the simplicity and speed of the Query Analyzer for example, but hated the built-in editor, which was really no better than a syntax coloring-capable Notepad. Now that we have Management Studio the management part seems a bit better but from a developer standpoint the tools is even worse. Visual Studio's excellent text editor... without a way to customize keyboard bindings!? Don't get me started on how unusable is the tree-based management hierarchy. Why can't I re-root the tree on a list of stored procs for example the way the Enterprise Manager used to allow? Now I have a treeview that needs to be scrolled horizontally, which makes it eminently useless. The SQL server support in Visual Studio is fantastic for working with stored procedures and functions, but it's terrible as a general ad hoc data query tool. I've tried various tools over the years but invariably they seem to focus on the management side and shortchange the developer in me. I just want something with basic admin capabilities, good keyboard support and requisite DDL functionality (ideally something like the Query Analyzer). At this point I'm seriously thinking of using vim+sqlcmd and a console... I'm that desperate :) Those of you who work day in and day out with SQL Server and Visual Studio... do you find the tools to be adequate? Have you ever wished they were better and if you have found something better, could you share please? Thanks!

  • Does DefaultAppPool run with special elevated privilegs on IIS?

    - by Leeks and Leaks
    I'm running a piece of code within a web page that queries the IIS metabase using ADSI. The code is as simple as this: DirectoryEntry iisNode = new DirectoryEntry("/LM/W3SVC/1/ROOT/MyAspWebsite-1-128886021498831845"); foreach (DirectoryEntry de in iisNode.Parent.Children) { System.Console.WriteLine(de.Name); } This works fine when I run the page/site under the DefaultAppPool on IIS7/W2K8. However when I create my own app pool and leave the properties the same as the default app pool, this code fails with the following error: Caught: System.Runtime.InteropServices.COMException Failed to parse virtual directory: /LM/W3SVC/1/ROOT/MyAspWebsite-1-128889542757187500 System.Runtime.InteropServices.COMException (0x80070005): Access is denied. What special privileges does the DefaultAppPool have? I don't see any documented. I need this to work in non default app pools, but without giving the entire worker process elevated privileges. I've also tried using the username and password parameters of the DirectoryEntry constructor, by using the Admin on the machine that IIS7 is running on, but that didn't change anything. I'll also note that this works fine on IIS6 and W2K3. Any help is appreciated.

  • My Website was hacked using Statcounter! Does Statcounter keep a record of cookies?

    - by Cyril Gupta
    I had a rather interesting case of hacking on my ASP.Net MVC website. For this website I had implemented a rather uncomplicated authentication system for my admin area -- an encrypted cookie which had an identifying signature for the member. Whenever the admin visits the website the cookie would be decrypted and signature verified. If matching he wouldn't have to sign in. Couple of days ago a visitor on my site told me that he was able to sign into my website simply by clicking no a referral link on his Statcounter console which pointed to my admin area (I had visited his site from a link inside my admin view). He just clicked on a link in statcounter and he was signed in as the admin! The only way this could have happened was if statcounter somehow recorded my cookies and used those when he clicked on the link pointing to my admin! Is that logical or fathomable? I don't understand what's going on. Do you have any suggestions as to how I can protect my website against things like this?

  • how to: dynamically load google ajax api into chrome extension content script

    - by Hoff
    Hi there, I'm trying to make use of google's ajax apis in a chorme extension's "content script". On a regular html page, I would just do this: <script src="http://www.google.com/jsapi"></script> <script> google.load("language", "1"); </script> But since I'm trying to load the tranlation library dynamically from js code, I've tried: script = document.createElement("script"); script.src = "http://www.google.com/jsapi"; script.type = "text/javascript"; document.getElementsByTagName("head")[0].appendChild(script); google.load('language','1') but the last line throws the following error: Uncaught TypeError: Object # has no method 'load' Funny enough, when i enter the same "google.load('language','1')" in chrome's js console, it works as intended... I've also tried with jquery's .getScript() but the same problem persists... Does anybody have any clue what might be the problem and how it could be solved? Many thanks in advance! Martin

  • Which LINQ expression is faster

    - by Vlad Bezden
    Hi All In following code public class Person { public string Name { get; set; } public uint Age { get; set; } public Person(string name, uint age) { Name = name; Age = age; } } void Main() { var data = new List<Person>{ new Person("Bill Gates", 55), new Person("Steve Ballmer", 54), new Person("Steve Jobs", 55), new Person("Scott Gu", 35)}; // 1st approach data.Where (x => x.Age > 40).ToList().ForEach(x => x.Age++); // 2nd approach data.ForEach(x => { if (x.Age > 40) x.Age++; }); data.ForEach(x => Console.WriteLine(x)); } in my understanding 2nd approach should be faster since it iterates through each item once and first approach is running 2 times: Where clause ForEach on subset of items from where clause. However internally it might be that compiler translates 1st approach to the 2nd approach anyway and they will have the same performance. Any suggestions or ideas? I could do profiling like suggested, but I want to understand what is going on compiler level if those to lines of code are the same to the compiler, or compiler will treat it literally. Thanks in advance for your help.

  • Is this correct for disposing an object using IDisposable

    - by robUK
    I have a class that implements the IDisposable interface. I am using a webclient to download some data using the AsyncDownloadString. I am wondering have I correctly declared my event handlers in the constructor and within the using statement of the web client? And is this correct way to remove the event handlers in the Dispose method? Overrule is this the correct way to use the IDisposable interface? public class Balance : IDisposable { //Constructor WebClient wc; public Balance() { using (wc = new WebClient()) { //Create event handler for the progress changed and download completed events wc.DownloadProgressChanged += new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged); wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); } } ~Balance() { this.Dispose(false); } //Get the current balance for the user that is logged in. //If the balance returned from the server is NULL display error to the user. //Null could occur if the DB has been stopped or the server is down. public void GetBalance(string sipUsername) { //Remove the underscore ( _ ) from the username, as this is not needed to get the balance. sipUsername = sipUsername.Remove(0, 1); string strURL = string.Format("https://www.xxxxxxx.com", sipUsername); //Download only when the webclient is not busy. if (!wc.IsBusy) { // Download the current balance. wc.DownloadStringAsync(new Uri(strURL)); } else { Console.Write("Busy please try again"); } } //return and display the balance after the download has fully completed void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { //Pass the result to the event handler } //Dispose of the balance object public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } //Remove the event handlers private bool isDisposed = false; private void Dispose(bool disposing) { if (!this.isDisposed) { if (disposing) { wc.DownloadProgressChanged -= new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged); wc.DownloadStringCompleted -= new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); wc.Dispose(); } isDisposed = true; } } }

  • Web Start Application built on NetBeans Platform doesn't create desktop shortcut & start menu item

    - by rudolfv
    I've created a NetBeans Platform application that is launched using Java Web Start. I built the WAR file using the 'Build JNLP Application'-command in Netbeans. I've added a desktop shortcut and menu item to the JNLP file, but for some reason, these are not created when the application is launched. However, when I go to: Control Panel - Java - Temporary Internet Files - View - Select my application Click 'Install shortcuts to the selected application' the desktop and menu shortcuts are created correctly. Also, in the Java Console, the Shortcut Creation option is set to the following (the default, I presume): Prompt user if hinted Below is a snippet of my JNLP file: <jnlp spec="6.0+" codebase="$$codebase"> <information> <title>${app.title}</title> <vendor>SomeVendor (Pty) Ltd</vendor> <description>Some description</description> <icon href="${app.icon}"/> <shortcut online="true"> <desktop/> <menu submenu="MyApp"/> </shortcut> </information> ... I'm stumped. Does anybody have an explanation for this? Thanks PS This is on both Windows XP and Windows 7. NetBeans version: 6.8

  • Alternate cause of BadImageFormatException in .NET Assembly?

    - by Phillip Knauss
    I'm working on a .NET 3.5 console application in C# which uses a VC++ unmanaged DLL. It ran without a problem when I worked on it a few weeks ago, but I'm coming back to it today and am now getting a BadImageFormatException ("An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)). My development workstation is running 64bit Windows 7, and I do a fair amount of work with unmanaged code, so I immediately checked that the .NET assembly and the VC++ library both had x86 targets. They did. Just to be sure, I cleaned and rebuilt the VC++ library and the .NET assembly, to no avail. Neither system is doing anything particularly unusual. The VC++ library loads a binary data file and does some mathematical processing on its contents. The .NET assembly has the DllImports for the library and some code to wire it up. This all worked a few weeks ago. So now I'm left wondering if there's some other cause of BadImageFormatException that's less common than an x86/x64 conflict that I might be running into. Thanks.

  • How to log correct context with Threadpool threads using log4net?

    - by myotherme
    I am trying to find a way to log useful context from a bunch of threads. The problem is that a lot of code is dealt with on Events that are arriving via threadpool threads (as far as I can tell) so their names are not in relation to any context. The problem can be demonstrated with the following code: class Program { private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); static void Main(string[] args) { new Thread(TestThis).Start("ThreadA"); new Thread(TestThis).Start("ThreadB"); Console.ReadLine(); } private static void TestThis(object name) { var nameStr = (string)name; Thread.CurrentThread.Name = nameStr; log4net.ThreadContext.Properties["ThreadContext"] = nameStr; log4net.LogicalThreadContext.Properties["LogicalThreadContext"] = nameStr; log.Debug("From Thread itself"); ThreadPool.QueueUserWorkItem(x => log.Debug("From threadpool Thread: " + nameStr)); } } The Conversion pattern is: %date [%thread] %-5level %logger [%property] - %message%newline The output is like so: 2010-05-21 15:08:02,357 [ThreadA] DEBUG LogicalContextTest.Program [{LogicalThreadContext=ThreadA, log4net:HostName=xxx, ThreadContext=ThreadA}] - From Thread itself 2010-05-21 15:08:02,357 [ThreadB] DEBUG LogicalContextTest.Program [{LogicalThreadContext=ThreadB, log4net:HostName=xxx, ThreadContext=ThreadB}] - From Thread itself 2010-05-21 15:08:02,404 [7] DEBUG LogicalContextTest.Program [{log4net:HostName=xxx}] - From threadpool Thread: ThreadA 2010-05-21 15:08:02,420 [16] DEBUG LogicalContextTest.Program [{log4net:HostName=xxx}] - From threadpool Thread: ThreadB As you can see the last two rows have no Names of useful information to distinguish the 2 threads, other than manually adding the name to the message (which I want to avoid). How can I get the Name/Context into the log for the threadpool threads without adding it to the message at every call?

  • ildasm and dynamic exe files

    - by TonyNeallon
    Hi There, I am trying to create an application can modify properties in IL to create a slightly different executable. E.g Client A runs app and a label on the WinForm label Reads "Client A:". Client B runs the app and Label Says "Client B". Easy I know using config files or resource files but thats not an option for this project. The Main program needs to be able to generate .exe file dynamically based on some form fields entered by user. My solution was to create a standalone executable that contained all the elements which I needed to make dynamic. I then used ildasm to generate the IL and thought that I could use this IL and substitute tags for the elements i wanted to make dynamic. I could then replace those tags at runtime after user filled the form using regex etc. The problem is, the if i re save the IL file generated by ILDASM as an exe and try to run it. I just launches console and does nothing. Am I going about this the wrong way? I didnt want to delve into Reflection as the dynamic .exe is a really simple one and I thought reverse engineering IL with ildasm would be the quickest way. You thoughts and pointers are much appreciated. Tony

  • Using MinHash to find similiarities between 2 images

    - by Sung Meister
    I am using MinHash algorithm to find similar images between images. I have run across this post, How can I recognize slightly modified images? which pointed me to MinHash algorithm. Being a bit mathematically challenged, I was using a C# implementation from this blog post, Set Similarity and Min Hash. But while trying to use the implementation, I have run into 2 problems. What value should I set universe value to? When passing image byte array to HashSet, it only contains distinct byte values; thus comparing values from 1 ~ 256. What is this universe in MinHash? And what can I do to improve the C# MinHash implementation? Since HashSet<byte> contains values upto 256, similarity value always come out to 1. Here is the source that uses the C# MinHash implementation from Set Similarity and Min Hash: class Program { static void Main(string[] args) { var imageSet1 = GetImageByte(@".\Images\01.JPG"); var imageSet2 = GetImageByte(@".\Images\02.TIF"); //var app = new MinHash(256); var app = new MinHash(Math.Min(imageSet1.Count, imageSet2.Count)); double imageSimilarity = app.Similarity(imageSet1, imageSet2); Console.WriteLine("similarity = {0}", imageSimilarity); } private static HashSet<byte> GetImageByte(string imagePath) { using (var fs = new FileStream(imagePath, FileMode.Open, FileAccess.Read)) using (var br = new BinaryReader(fs)) { //List<int> bytes = br.ReadBytes((int)fs.Length).Cast<int>().ToList(); var bytes = new List<byte>(br.ReadBytes((int) fs.Length).ToArray()); return new HashSet<byte>(bytes); } } }

  • I'v installed NetBeans 6.8 on my MacOS X MacBook and the logs say it cannot be run, any ideas?

    - by codezealot
    I've installed NetBeans 6.8 on my MacBook, and the installation results indicated success. However, every single time I attempt to run the application is shuts down. I monitored the process and noticed the following entries in the console that imply the application cannot be found? 3/19/10 10:20:20 PM [0x0-0x22022].org.netbeans.ide.baseide.200912041610[22168] /Applications/NetBeans/NetBeans 6.8.app/Contents/MacOS/netbeans: line 57: dirname: command not found 3/19/10 10:20:20 PM [0x0-0x22022].org.netbeans.ide.baseide.200912041610[22168] Cannot read cluster file: /../etc/netbeans.clusters 3/19/10 10:20:20 PM com.apple.launchd.peruser.501[77] ([0x0-0x22022].org.netbeans.ide.baseide.200912041610[22168]) Exited with exit code: 1 I started researching how to set the default JDK for use by NetBeans, and found repeated use of the following command line entry; netbeans --jdkhome /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home -- from http://wiki.netbeans.org/JDKVersionAndMacOS When I attempt the command line above, I receive "netbeans command not found". So do I ... 1.) Need to create a command called "netbeans" that points to my install location for NetBeans 6.8? If so how do I do that? 2.) How do I get to the netbeans.conf file for NetBeans 6.8, does one even exist for it? It gets even more interesting, the above happens with Eclipse as well. Yippie.

  • My Rails app is returning HTTP 500 for all its URLs, but nothing shows up in the log file. How can I

    - by mipadi
    I have a Rails app that is running on a production server with Apache and Phusion Passenger. The app works fine locally when using Mongrel, but whenever I try to load a URL on the production server, it returns HTTP 500. I know the server is working properly, because I can get the static elements of the application (e.g., JavaScript files, stylesheets, images) just fine. I've also checked the Passenger status and it is loading the app (it must be, since the app's 500 Internal Server Error page is returned, not just the default Apache one). Also, when I load the app via script/console production and do something like app.get("/"), 500 is also returned. The problem is that there is nothing in the log files to indicate the problem. production.log is empty. The Apache error logs show no problems with Apache, either. I'm stumped as to what's going on and I'm not sure how to diagnose the problem. I know I may have been a bit vague, but can anyone give a suggestion on what the problem may be? Or at least a way I can go about diagnosing it?

  • Node.js fetching Twitter Streaming API - EADDRNOTAVAIL

    - by Jordan Scales
    I have the following code written in node.js to access to the Twitter Streaming API. If I curl the URL below, it works. However, I cannot get it to work with my code. var https = require('https'); https.request('https://USERNAME:[email protected]/1.1/statuses/sample.json', function(res) { res.on('data', function(chunk) { var d = JSON.parse(chunk); console.log(d); }); }); But I receive the following node.js:201 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: connect EADDRNOTAVAIL at errnoException (net.js:642:11) at connect (net.js:525:18) at Socket.connect (net.js:589:5) at Object.<anonymous> (net.js:77:12) at new ClientRequest (http.js:1073:25) at Object.request (https.js:80:10) at Object.<anonymous> (/Users/jordan/Projects/twitter-stream/app.js:3:7) at Module._compile (module.js:441:26) at Object..js (module.js:459:10) at Module.load (module.js:348:31) If anyone can offer an alternative solution, or explain to me why this doesn't work, I would be very grateful.

  • Persist changes in C

    - by Mohit Deshpande
    I am developing a database-like application that stores a a structure containing: struct Dictionary { char *key; char *value; struct Dictionary *next; }; As you can see, I am using a linked list to store information. But the problem begins when the user exits out of the program. I want the information to be stored somewhere. So I was thinking of storing the linked list in a permanent or temporary file using fopen, then, when the user starts the program, retrieve the linked list. Here is the method that prints the linked list to the console: void PrintList() { int count = 0; struct Dictionary *current; current = head; if (current == NULL) { printf("\nThe list is empty!"); return; } printf(" Key \t Value\n"); printf(" ======== \t ========\n"); while (current != NULL) { count++; printf("%d. %s \t %s\n", count, current->key, current->value); current = current->next; } } So I am thinking of modifying this method to print the information through fprintf instead of printf and then the program would just get the infomation from the file. Could someone help me on how I can read and write to this file? What kind of file should it be, temporary or regular? How should I format the file (like I was thinking of just having the key first, then the value, then a newline character)?

  • Apache mod_deflate not compressing responses from Adobe BlazeDS

    - by DumCoder
    Hello, I have following setup Apache Box <=> Weblogic Box1 <=> Weblogic Box2 Apache Box : mod_weblogic(weblogic apache plugin), mod_deflate Weblogic Box1 : Weblogic 10.3 Weblogic Portal, Adobe BlazeDS Weblogic Box2 : Weblogic 10.3 SUN Jersey for REST API Apache forwards the request to Box1, where some of the REST requests get forwarded to Box 2 by Adobe BlazeDS. On Apache i have setup mod_deflate and mod_weblogic as follows: <IfModule mod_weblogic.c> WebLogicHost portalappeng.xxx.com WebLogicPort 7001 </IfModule> <Location /Portal> SetHandler weblogic-handler SetOutputFilter DEFLATE </Location> but when i look at the Apache deflate log i only see the jsp responses from Box1 being compressed, but the responses which BlazeDS forwarded to Box 2 are not compressed. Also the .js and .css files which are served from Box1 are not compressed Here are sample from log file, first response came directly from Box1 and got compressed, second and third also from Box1 but not compressed. Fourth one came from Box 2 to Box 1(BlazeDS) and then to Apache, not compressed. What am i missing? "GET /Portal/resources/services/userService/users?AppId=CM&CMUserType=ContentProducer&token=PSWNV8kb8db4WMBgWUjAbw%3D%3D&UserId=user123 HTTP/1.1" 711/7307 (9%) "GET /Portal/css/jquery-ui-1.7.2.custom.css HTTP/1.1" -/- (-%) "GET /Portal/framework/skins/shared/js/console.js HTTP/1.1" -/- (-%) "POST /Portal/messagebroker/http HTTP/1.1" -/- (-%)

  • git pull crashes after other member push something

    - by naiad
    Here it's the story... we have a Github account. I clone the repository ... then I can work with it, commit things, push things, etc ... I use Linux with command line and git version 1.7.7.3 Then other user, using Eclipse and git plugin for eclipse eGit 1.1.0 pushes something, and it appears in the github web pages as the last commit, but when I try to pull: $ git pull remote: Counting objects: 13, done. remote: Compressing objects: 100% (6/6), done. remote: Total 9 (delta 2), reused 7 (delta 0) Unpacking objects: 100% (9/9), done. error: unable to find 3e6c5386cab0c605877f296642d5183f582964b6 fatal: object 3e6c5386cab0c605877f296642d5183f582964b6 not found "3e6c5386cab0c605877f296642d5183f582964b6" is the commit hash of the last commit, done by the other user ... there's no problem at all to browse it through web page ... but for me it's impossible to pull it. It's strange, because my command line output tells about that commit hash, so it knows that one is the last one commit in the github system, but my git can not pull it ! Maybe the git protocol used in eGit is incompatible with the console git 1.7.7.3...
