  • jQuery AJAX not redirecting?

    - by MidnightLightning
    I have a simple PHP page (for testing) that simply calls header("Location: http://www.example.com");exit;, which resides on the same server, in the same directory as another file with the following jQuery Javascript: $(document).ready(function() { jQuery.ajax({ type : 'GET', url : 'bounce.php', error : function(xhr, status, error) { console.log("ERROR: ", xhr, xhr.status, xhr.getAllResponseHeaders()); }, complete : function(xhr, status) { // Get headers of the response console.log("COMPLETE: ", xhr, xhr.status, xhr.getAllResponseHeaders()); } }); }); I was expecting (from several other StackOverflow responses) for the xhr.status to return "302", but instead the AJAX call is triggering the "error" event (and then the "complete" event), and xhr.status is returning 0 (zero), and .getAllResponseHeaders() is coming back null (in both the error, and complete functions). Firebug is showing the "302 Moved Temporarily", and the response headers. So why is this triggering the error event, and not passing along the proper 302 code, and headers? Is this something to do with the Same Origin since the bouncing script and the fetching script are both on the same server? Is this jQuery or Javascript's fault?

  • Warning when using qsort in C

    - by controlfreak123
    I wrote my comparison function int cmp(const int * a,const int * b) { if (*a==*b) return 0; else if (*a < *b) return -1; else return 1; } and i have my declaration int cmp (const int * value1,const int * value2); and I'm calling qsort in my program like so qsort(currentCases,round,sizeof(int),cmp); when i compile it I get the following warning warning: passing argument 4 of ‘qsort’ from incompatible pointer type /usr/include/stdlib.h:710: note: expected ‘__compar_fn_t’ but argument is of type ‘int (*)(const int *, const int *)’ The program works just fine so my only concern is why it doesn't like the way im using that?

  • Paypal subscription API - transaction variables not POSTed

    - by morpheous
    I am writing a payments system based around paypal, I am using the HTML 'API'. I am passing the following form fields to PayPal: 'rm' = 2 'return = http://www.example.com/payment-handler.php?token=sometoken Where 'token' is a token I generated. According to the paypal documentation, a return method (rm) of 2 indicates to Paypal that the transaction data be posted back to the callback url using the POST method. When processing items using 'buy_now' buttons, the transaction items are correctly POSTed to my callback url (payment-handler.php), but for 'subscribe' operations, although the callback url is called, no POST data is sent to the url, and also, the 'token' field is missing. Instead, there is a parameter called 'auth'. I cant see anything in the paypal docs about a 'auth' field - so I dont know whats generating it and if I can reliably using it. Can anyone shed some light on this?

  • Is this a violation of the single responsiblity principle?

    - by L. Moser
    I have the following method and interface: public object ProcessRules(List<IRule> rules) { foreach(IRule rule in rules) { if(EvaluateExpression(rule.Exp) == true) return rule.Result; } //Some error handling here for not hitting any rules } public interface IRule { Expression Exp; Object Result; int Precedence; } Because rules have a precedence, they should actually never be processed out of order. This leads me with (I think) three solutions: Sort rules before passing them into the evaluator. Change the parameter type to something that enforces a sort order. Sort within the evaluator. I like option 3 because it always ensures that it is sorted and I like option 1 because it seems more cohesive. And option 2 seems like a good compromise. Is a scenario like this context specific/subjective, or is there really a best practice to be applied here?

  • How to split a path platform independent?

    - by Janusz
    I'm using the following code to get an array with all sub directories from a given path. String[] subDirs = path.split(File.separator); I need the array to check if certain folders are at the right place in this path. This looked like a good solution until findBugs complains that File.separator is used as a regular expression. It seems that passing the windows file separator to a function that is building a regex from it is a bad idea because the backslash being an escape character. How can I split the path in a cross platform way without using File.separator? Or is code like this okay? String[] subDirs = path.split("/");

  • Get a tableview insertRowsAtIndexPaths to accept indexOfObject?

    - by Emil
    Hey. I have a code snippet that looks like this: [tableView beginUpdates]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[array indexOfObject:[array objectAtIndex:indexPath.row]]] withRowAnimation:UITableViewRowAnimationLeft]; [tableView endUpdates]; [tableView reloadData]; It gets executed when a user clicks on an accessory. The first part is only there to provide a smooth animation, and does not really matter, as the tableView is reloaded milliseconds later, but as I said, it's there to provide an animation. It is supposed to move a selected object from its current indexPath to the value from an array at the same indexPath. Obviously, this code does not work, so I just want to know what can be done to fix it? PS: I get a warning when compiling, too. The usual "passing argument 1 of 'arrayWithObject:' makes pointer from integer without a cast..." (line 3)

  • Workflow foundation 4.0 message correlation and error reporting

    - by Lygpt
    I have a workflow service that runs and performs a number of different operations (such as web service calls). If one of these operations fails I call an error reporting web service to notify a seperate system that one of my workflow operations has failed. As the error could be something like the web service being down, I loop and retry this operation until it works. There can be times though when the data I'm passing to this web service is faulty and it needs changing. So I need to be able to hook into this running (but delayed) workflow and change local workflow variables and then re-run the operation. I've looked at message correlation in workflow 4.0 to achieve this but because the delay activity is active in my running workflow instance, any second service call doesn't do anything (it's like the delay activity is blocking any other requests). I've tried setting 'CanCreateInstance' to both true and false but it doesn't help. Thanks!

  • Missing output when running system command in perl/cgi file

    - by aladine
    I need to write a CGI program and it will display the output of a system command: script.sh echo "++++++" VAR=$(expect -c " spawn ssh -o StrictHostKeyChecking=no $USER@$HOST $CMD match_max 100000 expect \"*?assword:*\" send -- \"$PASS\r\" send -- \"\r\" expect eof ") echo $VAR echo "++++++" In CGI file: my $command= "ksh ../cgi-bin/script.sh"; my @output= `$command`; print @output; Finally, when I run the CGI file in unix, the $VAR is a very long string including \n and some delimiters. However, when I run on web server, the output is ++++++ ++++++ So $VAR is missing when passing in the web interface/browser. I know maybe the problem is $VAR is very long string. But anyway, is there anyway to solve this problem except writing the output to a file then retrieve it from browser? Thanks if you are interested in my question.

  • Using attribute text value in AngularJS directive

    - by C1pher
    Using a YouTube tutorial created by John Lindquist, I was able to create a directive using a template. See fiddle: http://jsfiddle.net/37PSs/ Now, I want to use the value of the attribute as a variable to a function call. Something like this: html: <hello-world name="World"></hello-world> javascript - directive: template: '<span>myFunction({{name}})</span>' javascript - myFunction(theirName): return ("Hello, " + String(theirName) + "!"); The closest I've been able to get is passing an [object Window] to my function.

Here's what i did (Not sure if i am doing it right) Create a project, build the code. Add the jar file into my current project lib. but i am still getting error from codes. Example double LToY(double y) { return Math.round( offset - radius * Double.longBitsToDouble(MicroDouble.log( Double.doubleToLongBits( (1 + Math.sin(Math.toRadians(y))) / (1 - Math.sin(Math.toRadians(y))) ) )) / 2); } Am i missing any import statment??? Btw i am using netbeans 6.5. Thanks for any guidance... Kevin

  • Binding to Element's Visibility value

    I have a checkable DropDownButton and a Grid. I want to bind Button's IsChecked parameter with grid's Visibility value. If (Visibility == Visible) IsCheked = true I've tried to do like that: IsChecked="{Binding ElementName=UsersDockWindow, Path=IsVisible}" but it didn't work, cause IsVisible is readOnly property.

  • When giving DataSource to a BindingSource shows only the cachedList Items.

    - by gtas
    I have a BindingSource on a form with MyObject Datasource. I Open another form and passing MyObject where i give its EntitySetObject reference to another BindingSource. Everything ok. Deleting an Entity on EntitySetObject reference and closing the form with EndEdit(). OK. Back in the "First" form i add one Entity in MyObject.EntitySetObject and again opening the form. But i have noticed that when giving the datasource to the BindingSource i have 2 items in cachedlist and 3 entities. Control now shows only the 2 cached items. Any Idea?

  • Java -Xms initial size effects

    - by SyBer
    Hi. What is the benefit of setting the -Xms parameter, and having the initial memory larger for example, then the default calculated one (64 MB in my case, according to Java GC tunning: http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html#par_gc.ergonomics.default_size)? Also, is there any good to setting both the initial and maximum memories to same size? Thanks.

  • Problem with order by in LINQ

    - by vikitor
    Hi, I'm passing from the controller an array generated by the next code: public ActionResult GetClasses(bool ajax, string kingdom) { int _kingdom = _taxon.getKingdom(kingdom); var query = (from c in vwAnimalsTaxon.All() orderby c.ClaName select new { taxRecID = c.ClaRecID, taxName = c.ClaName }).Distinct(); return Json(query, JsonRequestBehavior.AllowGet); } The query List should be ordered, but it doesn't work, I get the names of the classes ordered wrong in the array, because I've seen it debugging that the names are not ordered.The view is just a dropdownbox loaded automatically, so I'm almost sure the problem is with the action. Do you see anything wrong?Am I missing something?

  • adding tabs to tabcontrol from inside usercontrol

    - by Jakob
    How can I add tabs to a tabcontrol that exists in one usercontrol from another usercontrol that is contained within a tab itself?? Can I do it without passing in the tabcontrol as a parameter in the constructor, perhaps via some static global method? I've tried public static ObservableTabCollection FindCollectionFromUC(this DependencyObject depObject) { bool loop = true; var parent = (VisualTreeHelper.GetParent(depObject) as FrameworkElement); while (loop) { if (parent.GetType() is TabControl) { loop = false; return ((ObservableTabCollection)((TabControl)parent).ItemsSource); } } return null; } but this is just an infinite loop

  • Convert Option[Object] to Option[Int] Implicitly

    - by wheaties
    I'm working with legacy Java code which returns java.lang.object. I'm passing it into a function and I'd like to do some implicit conversions as such: implicit def asInt( _in:Option[Object] ) = _in asInstanceOf[ Option[Int] ] implicit def asDouble( _in:Option[Object] = _in asInstanceOf[ Option[Double] ] private def parseEntry( _name:String, _items:Map[String,Object] ) = _name match{ case docName.m_Constants => new Constants( _items get( Constants m_Epsilon ), _items get( Constant m_Rho ), _items get( Constants m_N ) ) Technically it goes on but I keep getting the same errors: expected Int, Option[Object] found. How have I done my implicits wrong? I was hoping it would do the transformation for me instead of me having to write "asInstanceOf" each and every time.

  • Help with linq to sql compiled query

    - by stackoverflowuser
    Hi I am trying to use compiled query for one of my linq to sql queries. This query contains 5 to 6 joins. I was able to create the compiled query but the issue I am facing is my query needs to check if the key is within a collection of keys passed as input. But compiled queries do not allow passing of collection (since collection can have varying number of items hence not allowed). For instance input to the function is a collection of keys. Say: List<Guid> InputKeys List<SomeClass> output = null; var compiledQuery = CompiledQueries.Compile<DataContext, IQueryable<SomeClass>>( (context) => from a in context.GetTable<A>() where InputKeys.Contains(a.Key) select a); using(var dataContext = new DataContext()) { output = compiledQuery(dataContext).ToList(); } return output; Is there any work around or better way to do the above?

  • How to set timeout with python-mechanize?

    - by Michal Cihar
    I'm using python-mechanize to scrape some web sites, which sometime simply don't respond to requests and these requests stay open too long, so I need to limit timeout for these requests. While using urlopen method, the timeout can be set using timeout parameter, but I have not found easy way for doing it with high level API such as submit or click methods. Ideally the timeout would be set just once for whole browser class and all calls would honor that. It would be probably possible to customize this by passing custom request_class to every click and submit call, but this would just pollute the code, so I'm looking for nicer solution for setting timeout for mechanize's browser class (and no, I don't want to change default socket timeout using socket.setdefaulttimeout).

  • Sorting and indexing into a list in a Django template?

    - by slypete
    How can you perform complex sorting on an object before passing it to the template? For example, here is my view: @login_required def overview(request): physicians = PhysicianGroup.objects.get(pk=physician_group).physicians for physician in physicians.all(): physician.service_patients.order_by('bed__room__unit', 'bed__room__order', 'bed__order') return render_to_response('hospitalists/overview.html', RequestContext(request, {'physicians': physicians,})) The physicians object is not ordered correctly in the template. Why not? Additionally, how do you index into a list inside the template? For example, (this doesn't work): {% for note_type in note_types %} <div><h3>{{ note_type }}</h3> {% for notes in note_sets.index(parent.forloop.counter0) %} #only want to display the notes of this note_type! {% for note in notes %} <p>{{ note }}</p> {% endfor %} {% endfor %} </div> {% endfor %}

  • Custom Display Form with Custom Workflow button

    - by Ifi
    I have created a new custom list form that will show 4 fields on the page from a Custom List called "Shipment". I have added Form Action button that I would like to run a custom action that is set inside of a Workflow. Currently, the form displays the fields for "Manifest Number", "Pickup Location", "Delivery Location", & "Scheduled Pickup Time". When the user clicks the Form Action button, what I want the Workflow to do is go to the ID field of the displayed content in the Form and change the value of the "Picked Up" column from No to Yes. The problem I am having is passing the ID of the displayed information from the Form to the Workflow as a variable. I can get the "Picked Up" column to update if I specify the value in the "Update List Item" window under the "Find the List Item" section, but I cannot figure out how to do this dynamically from the Form
