• 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?

• 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!

• 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.

• 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.

• Why do child elements cause 'dropleave' to be called (drag-n-drop file upload)?

  - by tundoopani

  I have a HTML5 drag-n-drop script that allows users to drop files in #droparea. The #droparea div has child elements that are also div elements. <div id="droparea"> <div id="showif_no_dragover">Drag files here!</div> <div id="showif_dragover">Drop the files!</div> </div> The associated javascript/jquery is: var droptarget = "#droparea"; $(droptarget).live('dragenter', dragEnter); $(droptarget).live('dragleave', dragExit); $(droptarget).live('dragover', nothing); $(droptarget).live('drop', dropGo); (Side question: should I use .live(), .on() or .bind() here?) I have created a sample jsFiddle with some additional code here: http://jsfiddle.net/PwFr9/3/ If you look at the console, you will notice that as you drag a file within #droparea, dragenter() and dragleave() are called multiple times, even though the drag is still inside #droparea. If you remove the child elements (#child1 and #child2), the problem is gone because the child elements are gone. How can I keep the child elements and prevent them from messing up the drag events? I have searched Stackoverflow and Google for hours without much help. I found this questions here at Stackoverflow: How to keep child elements from interfering with HTML5 dragover and drop events? I don't know why it works, though. I have tried placing 2 div elements on top of each other (via CSS positioning). The top-most div has the drag events attached whereas the bottom-most div has the child elements. I do not like this approach because it doesn't work with the rest of my page and does not allow mouse-click interaction with the bottom-most div. Any help is appreciated! Thank you in advance. Regards, tundoo

• How to define Module and use it in dojo with AMD?

  - by Devdatta Tengshe

  I am maintaining and extending an old project which was pre-AMD. I wish to add an Chart to the application. for this, I have created a js file as follows: define(["dojox/charting/Chart",...."dijit/Dialog","dojo/dom-construct"], function (Chart) { function showDailyChart(data){ //code to show the chart in a dialog } return customModules.singleChart; }); I have saved this file as /customModules/singleChart.js In My main HTML Page, I have added it to the packages as follows: var dojoConfig = { parseOnLoad: true, packages: [....,{"name":"customModules", "location":location.pathname.replace(/\/[^/]+$/, "")+"/modules" } ]}; The function from which I want to call it, is pre-AMD. So I am calling it as follows: dojo.require("customModules.singleChart"); . . . customModules.singleChart.showDailyChart(data); I can see that /customModules/singleChart.js is loaded in the Firebug console as well as Net Tab. However there is no customModules.singleChart object. Strangely enough there is no error either. I have tested this in Firebug, as well as Google Chrome's developer tools. What is the correct way to call an AMD Module using dojo.require? Or is there a better way to do what I need?

• 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

• 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; } } }

• 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.

• 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?

• 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...

• django: cannot import settings, cannot login to admin, cannot change admin password

  - by xpanta

  Hi, It seems that I am completely lost here. Yesterday I noticed that I cannot login to the admin panel (don't use it much, so it's been some weeks since last login). I thought that I might have changed the admin password and now I can't remember it (though I doubt it). I tried django-admin.py changepassword (using django 1.2.1) but it said that 'changepassword' is unknown command (I have all the necessary imports in my settings.py. Admin interface used to work ok). Then I gave a django-admin.py validate. Then the hell begun. django-admin.py validate gave me this error: Error: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined. I then gave a set DJANGO_SETTINGS_MODULE=myproject.settings and then again a django-admin.py validate This is what I get now: Error: Could not import settings 'myproject.settings' (Is it on sys.path? Does it have syntax errors?): No module named myproject.settings and now I am lost. I tried django console and sys.path.append('c:\workspace') or sys.append('c:\workspace\myproject') but still get the same errors. I use windows 7 and my project dir is c:\workspace. I don't use a PYTHONPATH variable (although I tried setting it temporarily to C:\workspace but I still get the same error). I don't use Apache, just the django development server. What am I doing wrong? My web page works fine. I think that the fact that I can't login as admin is related to the previous import error, no? PS: I also tried this: http://coderseye.com/2007/howto-reset-the-admin-password-in-django.html but still I couldn't change admin password for some reason. Although I could create another admin user (with which I couldn't login).

• Objects in JavaScript defined and undefined at the same time (in a FireFox extension)

  - by Alexey Romanov

  I am chasing down a bug in a FireFox extension. I've finally managed to see it for myself (I've only had reports before) and I can't understand how what I saw is possible. One error message from my extension in the Error Console is "gBrowser is not defined". This by itself would be surprising enough, since the overlay is over browser.xul and navigator.xul, and I expect gBrowser to be available from both. Even worse is the actual place where it happens: line 101 of nextplease.js. That is, inside the function isTopLevelDocument, which is only called from onContentLoaded, which is only called from onLoad here: gBrowser.addEventListener(this.loadType, function (event) { nextplease.loadListener.onContentLoaded(event); }, true); So gBrowser is defined in onLoad, but somehow undefined in isTopLevelDocument. When I tried to actually use the extension, I got another error: "nextplease is not defined". The interesting thing is that it happened on lines 853 and 857. That is, inside the functions nextplease.getNextLink = function () { nextplease.getLink(window.content, nextplease.NextPhrasesMap, nextplease.NextImagesMap, nextplease.isNextRegExp, nextplease.NEXT_SEARCH_TYPE); } nextplease.getPrevLink = function () { nextplease.getLink(window.content, nextplease.PrevPhrasesMap, nextplease.PrevImagesMap, nextplease.isPrevRegExp, nextplease.PREV_SEARCH_TYPE); } So nextplease is somehow defined enough to call these functions, but isn't defined inside them. Finally, executing typeof(nextplease) in Execute JS returns "object". Same for gBrowser. How can this happen? Any ideas?

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

  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.

• 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?

• 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)?

• Eclipse on windows doesnt start

  - by sap

  I usually do all my java development on linux, using fedora package manager setting up a development environment is easy and fast. Now I have to start using windows but I never used it for java development and im having a few difficulties having it setup. So I downloaded and installed thye java 6 JDK (just the standard edition, not the EE) and installed it. Next I downloaded eclipse classic package, which doesnt have an installer, you just unzip it and run it. I had to add the java bin directory to the PATH variable, which I did. But when I start eclipse.exe I get this: http://img02.imagefra.me/img/img02/1/12/12/f_12c33ivd2m_c79c09f.jpg I already made a new environment variable called CLASSPATH and add the d:/java sdk/lib directory to it, but it the same thing. Am I missing something? Thanks. UPDATE: so i wrote the path to the java.exe on the eclipse.ini file (linking to jvm.dll didnt work) and now it just opens a console window for a few seconds and then closes (doesnt output anything). also launching it like: java -jar plugins/org.eclipse.equinox.launcher_1.0.0.v20070208a.jar make the vm work for about 1-2 seconds and then it returns, with no outputs. UPDATE2: i didnt know it was writting a log file, found it and read it and it said i was using GWT x32 libraries on a x64 VM, so i just downloaded an eclipse x64 version and it worked. i still had to use the .ini trick to say where the JVM is installed. thanks a lot for the help.

• How do you replicate changes from one excel sheet to another in two separate excel apps?

  - by incognick

  This is all in C# .NET Excel Interop Automation for Office 2007. Say you create two excel apps and open the same workbook for each application: app = new Excel.ApplicationClass(); app2 = new Excel.ApplicationClass(); string fileLocation = "myBook.xslx"; workbook = app.Workbooks.Open(fileLocation, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing); workbook2 = app2.Workbooks.Open(fileLocation, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing); Now, I want to replicate any changes that occur in workbook2, into workbook. I figured out I can hook up the SheetChanged event to capture cell changes: app.SheetChange += new Microsoft.Office.Interop.Excel.AppEvents_SheetChangeEventHandler(app_SheetChange); void app_SheetChange(object Sh, Microsoft.Office.Interop.Excel.Range Target) { Excel.Worksheet sheetReadOnly = (Excel.Worksheet)Sh; string changedRange = Target.get_Address(missing, missing, Excel.XlReferenceStyle.xlA1, missing, missing); Console.WriteLine("The value of " + sheetReadOnly.Name + ":" + changedRange + " was changed to = " + Target.Value2); Excel.Worksheet sheet = workbook.Worksheets[sheetReadOnly.Index] as Excel.Worksheet; Excel.Range range = sheet.get_Range(changedRange, missing); range.Value2 = Target.Value2; } How do you capture calculate changes? I can hook onto the calculate event but the only thing that is passed is the sheet, not the cells that were updated. I tried forcing an app.Calculate() or app.CalculateFullRebuild() but nothing updates in the other application. The change event does not get fired when formulas change (i.e. a slider control causes a SheetCalculate event and not a SheetChange event) Is there a way to see what formulas were updated? Or is there an easier way to sync two workbooks programmatically in real time?

• 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?

• WCF Discovery finds endpoint but host is "localhost"

  - by Flo

  I am trying to use the Discovery feature in WCF using http://msdn.microsoft.com/en-us/library/dd456783(v=VS.100).aspx as a starting point. It works fine on my machine, but then I wanted to run the service on a different machine. The service was discovered properly but the hostname of the found service is always "localhost" which is of course not much use. Service Endpoint: var endpointAddress = new EndpointAddress(new UriBuilder { Scheme = Uri.UriSchemeNetTcp, Port = port}.Uri); var endpoint = new ServiceEndpoint(ContractDescription.GetContract(typeof(IServiceInterface)), new NetTcpBinding (), endpointAddress); Client: static EndpointAddress FindServiceAddress<T>() { Stopwatch stopwatch = new Stopwatch(); stopwatch.Start(); DiscoveryClient discoveryClient = new DiscoveryClient(new UdpDiscoveryEndpoint()); // Find endpoints FindResponse findResponse = discoveryClient.Find(new FindCriteria(typeof(T))); Console.WriteLine(string.Format("Searched for {0} seconds. Found {1} Endpoint(s).",stopwatch.ElapsedMilliseconds / 1000,findResponse.Endpoints.Count)); if (findResponse.Endpoints.Count > 0) { return findResponse.Endpoints[0].Address; } return null; } Should I simply set the Host to System.Environment.MachineName?

• Javascript for loop with variable

  - by Jascination

  I'm doing some simple javascript learning at the moment and I'm stuck on how to solve this problem. (the basic form comes from Code Academy). The task is to create 3 rabbit objects, each with a different adjective as an attribute. Then, print describeMyself() for each rabbit. Instead of repeating myself 3 times, I'd like to find a way to solve the problem with a for loop to make it more streamlined/challenging for myself. Here's what I tried: function Rabbit(adjective) { this.adjective = adjective; this.describeMyself = function() { console.log("I am a " + this.adjective + " rabbit"); }; } var rabbit1 = new Rabbit(fluffy); var rabbit2 = new Rabbit(happy); var rabbit3 = new Rabbit(sleepy); for (i=1; i<=3; i++){ ("rabbit"+i).describeMyself(); } Obviously, the ("rabbit"+i).describeMyself() is wrong. I want the loop to create "rabbit1", "rabbit2" and "rabbit3". What's the proper syntax here?

• Log4Net GetLogger creates rolling files even for the unreferenced files

  - by ybastiand

  Hi, I have a C# solution that contains three executables. I have each of these three executables sharing the same log4net configuration file. At startup of each of the executable, they retrieve a logger (one logger per executable, as per configuration file further below). When one of the executable performs Log.GetLogger(), it creates all the rolling files instead of only the one rolling file that is referred to as appender-ref in the executable's logger configuration. For instance, when I startup my sending daemon executable, it performs Log.GetLogger("SendingDaemonLogger") which creates 3 files Log/RuleScheduler.txt, Log/NotificationGenerator.txt and Log/NotificationSender.txt instead of only the desired Log/NotificationSender.txt. Then when I startup another of the executables, for instance the rule scheduler daemon, this other process cannot write in Log/RuleScheduler.txt because it has been created and locked by the sending daemon process. I am guessing that there may be three different solutions to my problem: The GetLogger should only create the rolling file appenders that are referenced in the config I should have one config file per executable, this way each config file could list only one rolling file appender and starting each of the executable would not create the rolling files of the other daemons. I am however reluctant to do this because some of the configuration (SMTP appender, console appender) is shared between the daemons and I don't want to have duplicate copies to maintain. Unless there is a way to have a config file including another one? Maybe there is a way to configure the rolling file so that concurrent access across processes is allowed? This solution still isn't perfect in my opinion because any of the daemons should not be creating the rolling files of some other daemons. Thanks in advance for your help! I have difficulties for posting the config file properly here (this website interprets as HTML). Please go to the following link for seeing my log4net configuration file: log4Net configuration file

• Why does the OnDeserialization not fire for XML Deserialization?

  - by Jonathan

  I have a problem which I have been bashing my head against for the better part of three hours. I am almost certain that I've missed something blindingly obvious... I have a simple XML file: <?xml version="1.0" encoding="utf-8"?> <WeightStore xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Records> <Record actual="150" date="2010-05-01T00:00:00" /> <Record actual="155" date="2010-05-02T00:00:00" /> </Records> </WeightStore> I have a simple class structure: [Serializable] public class Record { [XmlAttribute("actual")] public double weight { get; set; } [XmlAttribute("date")] public DateTime date { get; set; } [XmlIgnore] public double trend { get; set; } } [Serializable] [XmlRoot("WeightStore")] public class SimpleWeightStore { [XmlArrayAttribute("Records")] private List<Record> records = new List<Record>(); public List<Record> Records { get { return records; } } [OnDeserialized()] public void OnDeserialized_Method(StreamingContext context) { // This code never gets called Console.WriteLine("OnDeserialized"); } } I am using these in both calling code and in the class files: using System.Xml.Serialization; using System.Runtime.Serialization; I have some calling code: SimpleWeightStore weight_store_reload = new SimpleWeightStore(); TextReader reader = new StringReader(xml); XmlSerializer deserializer = new XmlSerializer(weight_store.GetType()); weight_store_reload = (SimpleWeightStore)deserializer.Deserialize(reader); The problem is that I am expecting OnDeserialized_Method to get called, and it isn't. I suspect it might have something to do with the fact that it's XML deserialization rather than Runtime deserialization, and perhaps I am using the wrong attribute name, but I can't find out what it might be. Any ideas, folks?
