• Getting Http Status code number (200, 301, 404, etc.) from HttpWebRequest and HttpWebResponse

  - by James Lawruk

  I am trying to get the HTTP status code number from the HttpWebResponse object returned from a HttpWebRequest. I was hoping to get the actual numbers (200, 301,302, 404, etc.) rather than the text description. ("Ok", "MovedPermanently", etc.) Is the number buried in a property somewhere in the response object? Any ideas other than creating a big switch function? Thanks. HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://www.gooogle.com/"); webRequest.AllowAutoRedirect = false; HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse(); //Returns "MovedPermanently", not 301 which is what I want. Console.Write(response.StatusCode.ToString());

• Process.WaitForExit not triggering with __debugbreak

  - by Cypher2100

  I'm trying to write a program to test student code against a good implementation. I have a C++ console app that will run one test at a time determined by the command line args and a C# .net forms app that calls the c++ app once for each test. The goal is to be able to detect not just pass/fail for each test, but also "infinite" (5secs) loop and exceptions (their code dying for whatever reason). The problem is that not all errors kill the C++ app. If they corrupt the heap the system calls __debugbreak which pops up a window saying Debug Error! HEAP CORRUPTION DETECTED... My C# app is using Process.WaitForExit(5000) to wait, but this error doesn't count as an exit, so I see a timeout. So my question is, how can I either get the C# app to detect that this is an error OR how can I get the C++ app to die when this error occurs rather than giving a dialog box and asking if I want to debug?

• error: polymorphic expression with default arguments

  - by 0__

  This following bugs me: trait Foo[ A ] class Bar[ A ]( set: Set[ Foo[ A ]] = Set.empty ) This yields <console>:8: error: polymorphic expression cannot be instantiated to expected type; found : [A]scala.collection.immutable.Set[A] required: Set[Foo[?]] class Bar[ A ]( set: Set[ Foo[ A ]] = Set.empty ) ^ It is quite annoying that I have to repeat the type parameter in Set.empty. Why does the type inference fail with this default argument? The following works: class Bar[ A ]( set: Set[ Foo[ A ]] = { Set.empty: Set[ Foo[ A ]]}) Please note that this has nothing to do with Set in particular: case class Hallo[ A ]() class Bar[ A ]( hallo: Hallo[ A ] = Hallo.apply ) // nope Strangely not only this works: class Bar[ A ]( hallo: Hallo[ A ] = Hallo.apply[ A ]) ...but also this: class Bar[ A ]( hallo: Hallo[ A ] = Hallo() ) // ???

• Why wouldn't an S3 ACL "stick"?

  - by Chris Phillips

  We would like to set an ACL to allow access to one of our buckets with a partner account. We've tested the process on a test account and everything works fine. On our production account/buckets, however, we can set the ACL and see the update but as soon as we attempt to access the bucket from the other account we get a forbidden response. Afterwards, when we look at the ACL list for the bucket, the permission is gone. We've tried using both Amazon's new S3 tool in the AWS Management Console and CloudBerry Explorer and both tools exhibit exactly the same behavior. Using the same process to update an ACL from our test account works as expected ( the ACL update "sticks" ). What would cause the ACL to not "stick"? Does anyone have any ideas on how to fix/workaround the problem?

• initializing properties with private sets in .Net

  - by Martin Neal

  public class Foo { public string Name { get; private set;} // <-- Because set is private, } void Main() { var bar = new Foo {Name = "baz"}; // <-- This doesn't compile /*The property or indexer 'UserQuery.Foo.Name' cannot be used in this context because the set accessor is inaccessible*/ using (DataContext dc = new DataContext(Connection)) { // yet the following line works. **How**? IEnumerable<Foo> qux = dc.ExecuteQuery<Foo>( "SELECT Name FROM Customer"); } foreach (q in qux) Console.WriteLine(q); } I have just been using the private modifier because it works and kept me from being stupid with my code, but now that I need to create a new Foo, I've just removed the private modifier from my property. I'm just really curious, why does the ExecuteQuery into an IEnumerable of Foo's work?

• Mono 2.10.5 Runtime error on Ubuntu 11.10

  - by johnluetke

  I've install mono-runtime via apt in order to run my Mono console application on Ubuntu via SSH. However, when I run the command mono myapp.exe, It exits, with no message, and my program does nothing. If I throw the -v switch to Mono, such as mono -v myapp.exe, I get about 10k lines of output (as expected, -v is verbose), with the first few lines being: converting method System.OutOfMemoryException:.ctor (string) Method System.OutOfMemoryException:.ctor (string) emitted at 0xb7052c28 to 0xb7052c4b (code length 35) [myapp.exe] converting method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) Method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) emitted at 0xb7052c68 to 0xb7052cf6 (code length 142) [myapp.exe] converting method System.SystemException:.ctor (string) I read this as the runtime throwing an OutOfMemory exception, but the machine is under no intense load, has plenty of available RAM, and is running nothing other that system processes. I've removed and reinstalled Mono countless times, and have even run the executable on other machines perfectly fine. Am I missing something completely obvious here?

• Beginner, learning as I go - how to get C#/SQLite db set up and ready for testing?

  - by ChrisC

  I've messed with Access a little bit in the past, had one class on OO theory, and one class on console c++ apps. Now, as a hobby project, I'm undertaking to write an actual app, which will be a database app using System.Data.SQLite and C#. I have the db's table structure planned. I have System.Data.SQLite installed and connected to VS Pro. I entered my tables and columns in VS, but that's where I'm stuck. I really don't know how to finish the db set up so I can start creating queries and testing the db structure. Can someone give me guidance to online resources that will help me learn how to get the db properly set up so I can proceed with testing it? I'm hoping for online resources specific to beginners using C# and System.Data.SQLite, but I'll use the closest I can get. Thanks.

• Can't echo jquery (with ajax) variable in php

  - by Lars Kerff

  I'm trying to post a variable through ajax. But it won't echo the variable in php. This are the variables (these are working, seen in the log): $("#slider").bind("valuesChanged", function(e, data){console.log("min: " + data.values.min + " max: " + data.values.max);}); The Ajax part: $("#slider").bind("valuesChanged", function (e, data) { $.ajax({ type: "POST", dataType: "text", url: "../test.php", data: { minValue: data.values.min, maxValue: data.values.max }, async: false, success: function(data){ alert('yeah') }, error: function(xhr) { alert('fail') // if your PHP script return an erroneous header, you'll land here } }); }); </script> And php echo: <?php if ( $_POST ) { echo $_POST[ 'minValue' ]; } ?> Now why does it not echo the post? Thanks!

• Writing a line in a JTextArea from another class

  - by Christopher Nastovski

  I'm trying to use a Method in my class 'Visual' to write a line of code into a JTextArea and it prints when I call it from 'Visual' but when I call it from 'Login' It only prints Text into the Console, not to the TextArea. private static Visual Visual; Visual.WriteLine("I'm sorry, your username or password is incorrect. Please try again."); or private static Visual Visual = new Visual(); Visual.WriteLine("I'm sorry, your username or password is incorrect. Please try again."); Dont work form 'Login' But, WriteLine("Test"); works from 'Visual', the class that the method is in. Here's the method in 'Visual' public void WriteLine(String Text) { System.out.println(Text); SystemFeed.append(Text.toString() + "\n"); SystemFeed.setCaretPosition(SystemFeed.getDocument().getLength()); }

• Why is visual studio not aware that an integer's value is changing? (debugging)

  - by incrediman

  I have a few simple lines of code (below). [bp] indicates a breakpoint. for(int i=0;i<300;i++){} int i=0; cout<<i; [bp] for (i=0;i<200;i++){} When I debug this in visual studio, it tells me that i is equal to 300 on the breakpoint. Annoyingly, 0 is printed to the console. Is there any way to make it realize that two variables in different scopes can actually have the same name? I also want to add some code to the second loop and then debug it - but when I try to do that, i is consistently shown as 300. Very annoying.

• What does this error mean when using OpenAL in the iPhone Simulator?

  - by mystify

  I'm getting this in the console, when creating my OpenAL Sources and Buffers: Cannot find executable for CFBundle/CFPlugIn 0xf530d0 </Library/Audio/Plug-Ins/HAL/Hear.plugin> (not loaded) 2010-05-05 17:11:13.934 Testproj[43173:207] Cannot find function pointer HearCFPlugInFactory for factory 5268FAAB-0147-4272-93FD-4D60A2433C1C in CFBundle/CFPlugIn 0xf430d0 </Library/Audio/Plug-Ins/HAL/Hear.plugin> (not loaded) However, the sounds play nicely. I think HAL is not available on the iPhone, it's just on Mac OS X, right? Do you guys also get that error in the simulator when using OpenAL?

• Issues using UITapGestureRecognizers in Interface Builder

  - by 5StringRyan

  I'm attempting to use the UITapGestureRecognizer object that can be found in Interface Builder. I've dragged a single "UITapGestureRecognizer" from the object library to a single view xib. I then create an IBAction method from this tap gesture, for a simple test, I'm just printing an "NSLog" message to the console once there is a tap on the view. I've run this, and the tap method isn't being called. I right click the view in IB and I noticed that there is a warning "!" on the view's "Outlook Collections" I see: Outlook Collections gestureRecognizers - Tap Gesture Recognizer (!) The warning states: UIView does not have an outlet collection named gestureRecognizers. What do I need to do to remedy this?

• How to implement automatic reflection of direct SQL Updates of the underlying database, in an ActiveRecord in Ruby on Rails ?

  - by Vadim Eisenberg

  Hello ! I am new to Ruby on Rails and I have a (maybe naive) question: I want to implement reflection of direct SQL Updates of the underlying database in an ActiveRecord (and finally in the generated html). By "direct updates" I mean updating the database bypassing the ActiveRecord methods, for example by MySQL console. I guess here MySQL triggers could be used that would call some stored procedure that would cause the appropriate ActiveRecord to be reloaded. Is there some automatic handling of this scenario in ActiveRecord/Ruby on Rails ? Did somebody implement this scenario ? Can somebody recommend using other MVC frameworks to reflect direct changes in mapped databases ?

• Map Reduce job on Amazon: argument for custom jar

  - by zero51

  Hi all, This is one of my first try with Map Reduce on AWS in its Management Console. Hi have uploaded on AWS S3 my runnable jar developed on Hadoop 0.18, and it works on my local machine. As described on documentation, I have passed the S3 paths for input and output as argument of the jar: all right, but the problem is the third argument that is another path (as string) to a file that I need to load while the job is in execution. That file resides on S3 bucket too, but it seems that my jar doesn't recognize the path and I got a FileNotFound Exception while it tries to load it. That is strange because this is a path exactly like the other two... Anyone have any idea? Thank you Luca

• Incorrect error

  - by jspooner

  If you assign an invalid date (like December 39th) to a datetime column ActiveRecord returns a "can't be blank" error when is should probably return an error like "Not a valid date" My question. Is this expected rails behavior, a bug or, something that I could patch? class ExerciseLog < ActiveRecord::Base validates_presence_of :scheduled_datetime end Fire up the console. e = Log.new # lets set a date for Dec 39th which obviously doesn't exist e.scheduled_datetime = "2010-12-39" e.save => false # this is the confusing message since our form did post a valid date e.errors.on(:scheduled_datetime) => "can't be blank" e.scheduled_datetime = "2010-12-30" e.save => true I discovered this issue when I accidentally transposed the month and day values. btw This is in Rails 2.3.5

• Send and receive Array as GET/POST using querystring

  - by Vanwaril

  I've got the following code, but it doesn't seem to work: var post_req = { array: [ [ { param1: 'something', param2: 123 } ], [ ], [ ], [ { param2: 'something', param4: 1234, param1: 'hello' } ] ] }; var data_send = querystring.stringify(post_req); var request = client.request('POST', '/', headers); request.end(data_send); and if( req.method == 'POST' ) { req.addListener('data', function(chunk) { POST = querystring.parse(chunk); console.log(POST); } } I end up with 5 sub-arrays, corresponding to the 5 parameters in the objects but with extra '][' characters in their names: { array: [ { '][param1': 'something' } , { '][param2': '123' } , { '][param2': 'something' } , { '][param4': '1234' } , { '][param1': 'hello' } ] }

• google contacts api service account oauth2.0 sub user

  - by user3709507

  I am trying to use the Google Contacts API to connect to a user's contact information, on my Google apps domain. Generating an access_token using the gdata api's ContactsService clientlogin function while using the API key for my project works fine, but I would prefer to not store the user's credentials, and from the information I have found that method uses OAuth1.0 So, to use OAuth2.0 I have: Generated a Service Account in the developer's console for my project Granted access to the service account for the scope of https://www.google.com/m8/feeds/ in the Google apps domain admin panel Attempted to generate credentials using SignedJwtAssertionCredentials: credentials = SignedJwtAssertionCredentials( service_account_name=service_account_email, private_key=key_from_p12_file, scope='https://www.google.com/m8/feeds/', sub=user_email') The problem I am running into is that attempting to generate an access token using this method fails. It succeeds in generating the token when I remove the sub parameter, but then that token fails when I try to fetch the user's contacts. Does anyone know why this might be happening?

• JavaScript: function returning NAN

  - by Michael

  I'm working on a codecademy.com lesson with instructions to write the calculateTotal function below. When I click run, it's returning NaN. Anyone know what's wrong with the calculateTotal function as I wrote it that's making it return NaN. Note, I understand that NaN means not a number... // runner times var carlos = [9.6,10.6,11.2,10.3,11.5]; var liu = [10.6,11.2,9.4,12.3,10.1]; var timothy = [12.2,11.8,12.5,10.9,11.1]; // declare your function calculateTotal here var calculateTotal = function(raceTimes){ var totalTime; for(i = 0; i < raceTimes.length; i++){ totalTime += raceTimes[i]; return totalTime; } }; var liuTotal = calculateTotal(liu); console.log(liuTotal);

• Breakpoint pointing out "objc_autoreleaseNoPool"

  So I'm debugging an app in preperation for its app so release, and I enabled a universal breakpoint for "All Exceptions". Since then, everytime I run the app, the console prints: Catchpoint 2 (throw)Pending breakpoint 1 - "objc_exception_throw" resolved objc[11765]: Object 0x8f18ff0 of class __NSCFLocale autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug objc[11765]: Object 0x8f190a0 of class __NSCFNumber autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug objc[11765]: Object 0x8f1fef0 of class __NSCFLocale autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug Literally printed 3 times. I have no idea what this means but it looks bad. Any advice would be appreciated.

• Is it possible to get Logged in user Non Restricted token from a service on Vista?

  - by coolcake

  Hello All, I need to create a process with integrity level high, so that it can do all the administrative tasks. But the created process should run in the current logged in desktop i.e. it should not run in session 0. By default only administrators will log on to the console. The service should launch the process, as service is running in session 0 and system account. Can it any how get the non restricted token and use it in CreateProcessAsUser, so that the process created does have integrity level of high or system. Is it possible? One more thing is i should get the non restricted token with out prompting for user name or password of the logged in user. Thanks

• How to use Eclipse's Display View for Debug?

  - by jzd

  At the link below it explains that the "display view allows you to manipulate live code in a scrapbook type fashion (see Figure 8). To manipulate a variable, simply type the name of the variable in the Display view, and you'll be greeted with a familiar content assist." http://www.ibm.com/developerworks/library/os-ecbug/ However, I am having trouble getting it to work. I have the view open but all the buttons are disabled. I have tried putting code in the view, selecting code in the view, selecting code in other views, while running and while not running debug, but the only button that is ever enabled on the view is "clear console". Suggestions on what I am doing wrong?
