• Find the xmlHttpRequest resource in aspx page

  - by DJStroky

  I'm trying to find an xmlHttpRequest or similar resource that I can query directly to obtain an xml file for my own purposes. At this site it is possible to browse a Google Map mashup with markers. Unfortunately it is only possible to view all markers at a small view range, whereas I simply want to obtain all the information at once for the entire state. Using the firebug console in firefox I can enter the following javascript line to obtain the xml that I desire: document.getElementById("stationXML").value I tracked this document element down to an <input> tag, but I can't figure out how that input is set. Thanks in advance for your help!

• Why does a checkbox's "checked" attribute return the opposite of it's actual value on click event?

  - by Kappers

  I've got the following HTML <li><input type="checkbox" /><label>This is the label!</label></li> I bound a click event to the li, and let the click event bubble up to the li before doing anything else. $('li').each(function(i){ var item = $(this); var checkbox = $("input[type='checkbox']", item); item.bind('click', function(e){ var isChecked = checkbox.is(':checked'); console.log(isChecked); e.stopPropagation(); }); }); Starting with an unchecked checkbox, when the click event fires, isChecked returns true when I click on the checkbox, but returns false when I click on the label or li. Does anyone know why?

• Presentmodalviewcontroller method problem with retain count

  - by Infinity

  Hello guys! I am trying to present a modal view controller. I have read the documentation, but something is strange. Here's my code: NSLog(@"rc: %d", [modalViewController retainCount]); UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:modalViewController]; [self presentModalViewController:navigationController animated:YES]; [navigationController release]; NSLog(@"rc: %d", [modalViewController retainCount]); And on the console, appears: rc: 2 rc: 24 And I think 24 is very strange... What do you thin? Why is this happening?

• VB.NET Application which can compile and run C programs

  - by Arjun Vasudevan

  These days I'm working on a VB.NET application which can be used to edit, compile and run C programs. Can someone tell me how I can call a cl.exe process from within my VB program and also that how do I run the program in the console widow itself. Presently I have only the editor ready. With that one can type in a program and save it with a ".c" extension. Now there are 2 buttons on my form - "Compile" and "Run". When the user clicks on the "Compile" button, the program should be passed to the cl.exe process and the errors should be displayed in another textbox or the DOS(black screen itself). And when the user clicks on the "Run" button, the ".exe" file which just got created should get executed.

• How can I get Hudson to be able to access JUnit?

  - by Bedwyr Humphreys

  I've got Hudson running on TOMCAT, it can build my Netbeans project using the ant build.xml, but it won't run any of my unit tests because of what I assume is a problem with the classpath: package org.junit does not exist [javac] import org.junit.After; [javac] ^ But I've got the junit-4.8.1.jar on the classpath in /etc/environment and I can successfuly run the junit tests from a console using java org.junit.runner.JUnitCore org.junit.tests.AllTests My CLASSPATH is set to /home/bedwyr/junit4.8.1/junit-4.8.1.jar:. Am I going wrong somewhere or is there anything else I need to set? [edit] What I did was to export/include (using the ide) all libraries (including Junit) hudson then reads all it needs from the subversion repo. I then ran into an issue with exposing hudson to the internet, and pretty soon gave up on tomcat on ubuntu server (again, to do with the tomcat security manager) - glassfish is a lot smoother and that's where I am now - apache front end with ajp_proxy to hudson on glassfish.

• Rails shoulda and factory_girl setup

  - by kristian nissen

  I have installed both shoulda and factory_girl, I can run shoulda just fine, but when I add this: require 'factory_girl' Factory.define :user do |u| u.mail '[email protected]' u.pass 'secret' end to my test/test_helper.rb I'm getting this error: /test/test_helper.rb:1:in `require': no such file to load -- factory_girl (LoadError) when I execute rake test:units I have installed both gems using: sudo gem install thoughtbot-shoulda --source=http://gems.github.com sudo gem install thoughtbot-factory_girl --source=http://gems.github.com and can see both of them being installed fine. And by the way, this works fine as well: script/console Loading development environment (Rails 2.3.8) require 'factory_girl' = [] so requiring the gems seems to be working

• Ruby as a scripting language for web server

  - by Olivier Lalonde

  Is it possible to use Ruby as a scripting language with a HTTP server ? I'd like to be able to simply put some Ruby files in a web directory and be able to execute them from my browser - just like I did with PHP. I have absolutely nothing against frameworks such as RoR, but I was told that I should first learn Ruby and only then move on with higher level frameworks. Of course, I could write some Ruby scripts and run them in the console, but I would prefer getting the input/output from my browser :) Is that possible at all ? Otherwise, how hard would it be for me to build a quick and simple web framework ?

• FBConnect stream.publish with iphone unknown response?

  - by Tom G

  Hi All, I am using stream.publish to publish some info to a users wall. This all works fine. I am not using FBStreamDialog because i do not want the user to be able to edit the message..... So i have set up my own UI. It all works fine and the stream is published to the users wall, the only issue is that i do not understand the result obtained from the delegate method: - (void)request:(FBRequest*)request didLoad:(id)result { NSLog(@"result = %@", result); } I need to understand what the result is telling me so that i can handle any errors. Currently the following is being printed in the console but i do not know what this means: result = 100000874992250_117813161591916 Any help or advice regarding this issue would be highly appreciated. Thanks Tom

• NuGet - managing and removing mutil version packages in single solution

  - by Myles McDonnell

  SCENARIO One VS solution with n projects. Project A references package Y v1, Project B references package Y v2. It is now not possible to update all references to package Y for all projects in the solution using the NuGet package manage dialog at the solution level, it is only possible to do this when all projects reference the same version of package Y. Not a big deal for only two projects, but I'm dealing with lots of projects that through poor package management are referencing many package versions when they should all reference the same version. Before I spend the afternoon writing a console app. to auto update all package.config files for a solution so that each referenced package is only referenced via it's latest version (latest referenced, not the very latest, with exceptions/caveats etc)....is there a tool/method for doing this already? Or some other approach I am unaware of?

• Monkeypatch a model in a rake task to use a method provided by a plugin?

  - by gduquesnay.mp

  During some recent refactoring we changed how our user avatars are stored not realizing that once deployed it would affect all the existing users. So now I'm trying to write a rake task to fix this by doing something like this. namespace :fix do desc "Create associated ImageAttachment using data in the Users photo fields" task :user_avatars => :environment do class User # Paperclip has_attached_file :photo ... <paperclip stuff, styles etc> end User.all.each do |user| i = ImageAttachment.new i.photo_url = user.photo.url user.image_attachments << i end end end When I try running that though I'm getting undefined method `has_attached_file' for User:Class I'm able to do this in script/console but it seems like it can't find the paperclip plugin's methods from a rake task.

• aws-s3 can't find xml-simple, but in gem list

  - by Dan Donaldson

  I'm transitioning to heroku, and need to have AWS-s3 connections to deal with a variety of graphics. I've installed the aws-s3 gem, but one of its dependencies is not being found: xml-simple. My belief is that this is a standard part of RoR, and it is in the gem list. When I deploy to heroku, all is fine, but on my development server, it isn't being found when the code uses it to check the existence of a graphic. It works fine from the console, using s3sh. I'm not quite sure why this is -- what do I need to check? Using OS X 10.6, on a 64 bit machine -- can this be part of it?

• Remote JMX connection

  - by tuler

  I'm trying to open a JMX connection to java application running on a remote machine. The application JVM is configured with the following options: com.sun.management.jmxremote com.sun.management.jmxremote.port=1088 com.sun.management.jmxremote.authenticate=false com.sun.management.jmxremote.ssl=false I'm able to connect using localhost:1088 using jconsole or jvisualvm. But I'm not able to connect using xxx.xxx.xxx.xxx:1088 from a remote machine. There is no firewall between the servers, or on the OS. But to eliminate this possibility I telnet xxx.xxx.xxx.xxx 1088 and I think it connects, as the console screen turns blank. Both servers are Windows Server 2008 x64. Tried with 64-bit JVM and 32-bit, neither work.

  NSMutableURLRequest *jaikuRequest=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://api.jaiku.com/json"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; [jaikuRequest setHTTPMethod:@"POST"]; NSString *jbody= [NSString stringWithFormat:@"method=presence.send&user=XXusernameXX&personal_key=XXpersonalkeyXX&message=%@", encodedMsg]; [jaikuRequest setHTTPBody:[[NSString stringWithFormat:jbody] dataUsingEncoding:NSASCIIStringEncoding]]; I wrote the above code snippet to be able to post a jaiku on jaiku.com. I've come across similar samples in other languages for posting a jaiku. However i get the following response in the console: {"status": "error", "message": "Invalid API user", "code": 0} what could be the error or if im wrong, what is the correct approach to posting a jaiku using xcode?

• Use the [Serializable] attribute or subclassing from MarshalByRefObject?

  - by Theo Lenndorff

  I'd like to use an object across AppDomains. For this I can use the [Serializeable] attribute: [Serializable] class MyClass { public string GetSomeString() { return "someString" } } Or subclass from MarshalByRefObject: class MyClass: MarshalByRefObject { public string GetSomeString() { return "someString" } } In both cases I can use the class like this: AppDomain appDomain = AppDomain.CreateDomain("AppDomain"); MyClass myObject = (MyClass)appDomain.CreateInstanceAndUnwrap( typeof(MyClass).Assembly.FullName, typeof(MyClass).FullName); Console.WriteLine(myObject.GetSomeString()); Why do both approaches seem to have the same effect? What is the difference in both approaches? When should I favor the one approach over the other? EDIT: At the surface I know that there are differences between both mechanisms, but if someone jumped out of a bush and asked me the question I couldn't give him a proper answer. The questions are quite open questions. I hoped that someone can explain it better than I could do.

• jquery background image rotating script doesn't work

  I did my own feature using this: function save(title, url) { for (var i = 1; i < localStorage.length; i++) { localStorage["saved-title_" + i + ""] = title; localStorage["saved-url_" + i + ""] = url; } } function listFavs() { for (var i = 1; i < localStorage.length; i++) { console.log(localStorage["saved-fav-title_" + i + ""]); } } save() happens when someone clicks on this: onclick="save(\'' + title + '\', \'' + tab.url + '\');"> ' + title + '</a>'; However... it doesn't show the saved localStorages, how am I supposed to make it work?

• VC++ 2010 wants to link boost libararies i didn't even specify

  - by Philipp

  Hi there, I'm trying to build my application with MSVC 2010 instead of GCC. With GCC everything works fine. My app uses boost_system and boost_thread libraries. I built boost with VC2010 in "system" layout, that means the libraries are named just libboost_system.lib (and not libboost_system_compiler_threading_version_wtf_snafu.lib) The libs reside in C:\Boost\lib, the Makefile specifies LFLAGS = /NOLOGO /INCREMENTAL:NO /SUBSYSTEM:CONSOLE LIBS = /LIBPATH:C:/Boost/lib libboost_system.lib libboost_thread.lib Ws2_32.lib when invoking nmake it compiles, but when trying to link it quits with LINK : fatal error LNK1104: cannot open file 'libboost_date_time-vc100-mt-1_43.lib I mean seriously, WTF? I told it to link libboost_systen.lib and libboost_thread.lib how come it tries to link libboost_data_time and why does it assume I built the libs in "tagged" layout?? How can I stop MSVC trying to be smart and guess what I might have wanted to link? Thanks, Philipp

• How to re-use a thread in Java ?

  - by David

  I am a building a console Sudoku Solver where the main objective is raw speed. I now have a ManagerThread that starts WorkerThreads to compute the neibhbors of each cell. So one WorkerThread is started for each cell right now. How can I re-use an existing thread that has completed its work? The Thread Pool Pattern seems to be the solution, but I don't understand what to do to prevent the thread from dying once its job has been completed. ps : I do not expect to gain much performance for this particular task, just want to experiment how multi-threading works before applying it to the more complex parts of the code. Thanks

• C# Changing class method at run-time

  - by Flavio

  Hi, I need to extend the behavior of an instance, but I don't have access to the original source code of that instance. For example: /* I don't have the source code for this class, only the runtime instance */ Class AB { public void execute(); } in my code I would to intercept every call to execute, compute some sutff and then call the original execute, something like /* This is how I would like to modify the method invokation */ SomeType m_OrgExecute; { AB a = new AB(); m_OrgExecute = GetByReflection( a.execute ); a.execute = MyExecute; } void MyExecute() { System.Console.Writeln( "In MyExecute" ); m_OrgExecute(); } Is that possible? Does anyone have a solution for this problem?

• installing windows service with SC.exe or InstallUtil.exe - there is difference but which?

  - by LosManos

  hejdig. SC.exe and InstallUtil both install/uninstall windows services. But they don't seem to work the same way. What is the difference? For instance InstallUtil fails (some file or dependency not found error) while Sc create happily installs the service. Too add to the strangeness; the service doesn't show up if I run net start in the console. But it does show up in the services GUI. Variants of this happen when I try to uninstall. I have written the service myself and earlier versions work. Dotnet3.5. /OF
