  • Javascript get li values and encode them

    - by bluedaniel
    At the moment I have two (maybe more) unordered lists which are sortable with jquery and ui. The things that work are that the lists are connected, items are draggable, items can be removed and a form that adds to the list. What I need however is a function that gets all the content for li items and json encode them ready to be sent off to some db function, or something. Im new to jquery however and cant find documentation for li items. Hope Ive explained this well. Daniel

  • C++ Boost bind value type

    - by aaa
    hello. I look in documentation and source code but cannot figure out how to get return value type of boost bind functor. I am trying to accomplish following: 35 template<typename T,size_t N, class F> 36 boost::array<typename F::value_type, N> make_array(T (&input)[N], F unary) { 37 boost::array<typename F::value_type, N> array; 38 std::transform(input, input + N, array.begin(), unary); 39 return array; 40 } where F can be bind functor. the above does not work because functor does not have value_type. for that matter, is there standard interface for unary/binary functor as far as return value. Thanks

  • Google Contacts Data API and PHP

    - by pako
    I'm developing a PHP application to retrieve the list of contacts from a GMail account. I'm looking for a solution which would enable the user of my application to provide the login and password to their Gmail account in my application (as opposed to getting redirected to Google) and then automatically do the retrieval. The retrieval process can be run in PHP or JavaScript (which would then feed the list of contacts back to PHP using Ajax). Is it possible to do that? Which JavaScript API should I use for that? Can someone point me at the right chapter in Google Contacts Data API documentation?

  • default model field attribute in Django

    - by Rosarch
    I have a Django model: @staticmethod def getdefault(): print "getdefault called" return cPickle.dumps(set()) _applies_to = models.TextField(db_index=True, default=getdefault) For some reason, getdefault() is never called, even as I construct instances of this model and save them to the database. This seems to contradict the Django documentation: Field.default The default value for the field. This can be a value or a callable object. If callable it will be called every time a new object is created. Am I doing something wrong? Update: Originally, I had this, but then I switched to the above version to debug: _applies_to = models.TextField(db_index=True, default=cPickle.dumps(set())) I'm not sure why that wouldn't work.

  • Tabulated log file format with the python logging system

    - by yorjo
    Hi everybody, I'm using the python logging module with the "native" configuration file support (config.fileconfig) as describe in the documentation here : http://docs.python.org/library/logging.html (see the logging.conf file) I was wondering if it's possible to supply a tabulated data format in the configuration file? The sample configuration file is the following: [formatter_simpleFormatter] format=%(asctime)s - %(name)s - %(levelname)s - %(message)s I though that using the \t in the format would be enough but it doesn't. format=%(asctime)s\t%(name)s\t%(levelname)s\t%(message)s\t If I do so it print \t in the result. I tried a couple of thing without success. I suppose it's really easy to do but I don't find it! How can I do that?

  • jQuery way to handle select lists, radio buttons and checkboxes

    - by Álvaro G. Vicario
    When I handle HTML form elements with jQuery, I always end up with an ugly mix of jQuery syntax and plain JavaScript like, e.g.: function doStuff($combo){ if( $combo.get(0).options[$combo.get(0).selectedIndex].value=="" ){ var txt = ""; }else{ var txt = $combo.get(0).options[$combo.get(0).selectedIndex].text; } var $description = $combo.closest("div.item").find("input[name$=\[description\]]"); $description.val(txt); } Are there standard jQuery methods to handle typical operations on elements like <select>, <input type="radio"> and <input type="checkbox">? With typical, I mean stuff like reading the value of the selected radio button in a group or replacing elements in a selection list. I haven't found them in the documentation but I admit that method overloading can make doc browser kind of tricky.

  • Using a JSON web service from a Java client application

    - by user383341
    I am developing a client-side Java application that has a bit of functionality that requires getting data from some web services that transmit in JSON (some RESTful, some not). No JavaScript, no web browser, just a plain JAR file that will run locally with Swing for the GUI. This is not a new or unique problem; surely there must be some open source libraries out there that will handle the JSON data transmission over HTTP. I've already found some that will parse JSON, but I'm having trouble finding any that will handle the HTTP communication to consume the JSON web service. So far I've found Apache Axis2 apparently which might have at least part of the solution, but I don't see enough documentation for it to know if it will do what I need, or how to use it. Maybe part of the problem is that I don't have experience with web services so I'm not able to know a solution when I see it. I hope some of you can point me in the right direction. Examples would be helpful.

  • BlackBerry responseXML is null

    - by Andrew
    I'm trying to port a portion of AJAX code I wrote over to the BlackBerry application's embedded browser. Our base build is 4.6.1 and the RIM documentation claims that XMLHttpRequest's responseXML is available starting with this version. And when I request an XML file from my local server, I get back the responseText (so I know the request is working), but the responseXML is always null. I've made sure the HTTP "Content-Type" header is set to "text/xml" and I am getting the correct data loaded in a web browser. It's just nulling out in the BB web environment. Does anyone know what might be happening? A backup of using the responseText and piping it through DOMParser is not possible because that object was not added to the BB browser until 4.7.1. So I'm not sure what fallback I have.

  • Draw rectangle using Core Graphics with live preview

    - by mikawber
    I'm creating a simple drawing application and would like some help with drawing rectangles based on the user's touch events. I'm able to draw a rectangle using Core Graphics from the point in touchesBegan to the point in touchesEnded. This rectangle is then displayed once the touchesEnded event is fired. However, I would like to be able to do this in a 'live' fashion. Meaning, the rectangle is updated as the user drags their finger. Is this possible? Any help would be greatly appreciated, thank you!

  • Best method of including an abstract in a latex 'book'?

    - by olan
    Hello there. I've been looking for the answer to this question for a while now but can't seem to find it, so I'm hoping someone on here can help me. I'm writing up a thesis in Latex, and really like the \frontmatter, \mainmatter and \backmatter ability when using the "book" environment. However I need to add an abstract and the \begin{abstract} environment is undefined when creating a "book". If I change to a "report" however, I lose the functionality of the *matter terms. So what I really need to know is: is there a simple method of including an abstract in a "book" and have it formatted the same as it would be in a "report"? (i.e. centered vertically and horizontally with an 'abstract' heading) Thanks for any help! First post on stackoverflow after reading for months!

  • Can Grails exceptionHandler support the following Error Handling Flow

    - by Andrew
    In my rails app that I am porting to grails whenever an unexpected error occurs I intercept the error automatically and display a form to the user informing them that an error has occured and asking them for further information. Meanwhile, as the form is rendered I write the stack trace and other information about who was logged in to a database table. Then if the form is submitted I add that information to the error report. I cannot tell from the exceptionHandler documentation and BootStrap examples whether that will allow me to grab all the information including various session and request parameters and then stuff them into a database and then post a form. Any thoughts?

  • Why did the C# designers attach three different meanings to the 'using' keyword?

    - by gWiz
    The using keyword has three disparate meanings: type/namespace aliasing namespace import syntactic sugar for ensuring Dispose is called The documentation calls the first two definitions directives (which I'm guessing means they are preprocessing in nature), while the last is a statement. Regardless of the fact that they are distinguished by their syntaxes, why would the language developers complicate the semantics of the keyword by attaching three different meanings to it? For example, (disclaimer: off the top of my head, there may certainly be better examples) why not add keywords like alias and import? Technical, theoretical, or historical reasons? Keyword quota? ;-) Contrived sample: import System.Timers; alias LiteTimer=System.Threading.Timer; alias WinForms=System.Windows.Forms; public class Sample { public void Action { var elapsed = false; using(var t = new LiteTimer.Timer(_ => elapsed = true) { while (!elapsed) CallSomeFinickyApi(); } } } "Using" is such a vague word.

  • Accessing FILESTREAM from an SQL CLR assembly

    - by superware
    I'm trying to stream FILESTREAM data from an unsafe SQL CLR assembly. The connection string is Data Source=LAPTOP2\SQLEXPRESS;Initial Catalog=test;Integrated Security=True;Enlist=False When creating a new SqlFileStream (inside a SqlTransaction, of course), I'm getting: The request is not supported at OpenSqlFilestream. So I decided to try native OpenSqlFilestream, but then I'm getting an invalid handle (-1) while GetLastWin32Error returns that same: The request is not supported (ERROR_NOT_SUPPORTED). I have also tried SqlContext.WindowsIdentity.Impersonate() with no apparent effect. I couldn't find any documentation referencing this restriction. Is it really unsupported? If it is unsupported, is there a good reason? Does anyone know of a workaround?

  • C# How to place a comma after each word but the last in the list

    - by user576712
    I totally new to C# and learning as I go. I am stuck on issue which I'm hoping an experienced programmer can help. I have added a CheckedListBox to my form and added a collection of 6 items to it. I need all but the last item selected to have a comma placed beside it, so my question is: how can I tell C# NOT to place a comma beside the last item selected? foreach (object itemChecked in RolesCheckedListBox.CheckedItems) { sw.Write(itemChecked.ToString() + ","); } Thanks for any help received!

  • Where to install shared DLLs on Windows

    - by BruceCran
    I have a driver which can be installed on Windows (XP/Vista/7). It's accessed via a DLL that applications link to, and which is also a Winsock Provider (WSP). It used to be installed under System32, but having seen advice not to, I changed it to install under ProgramFiles instead. Now, the problem is that people are having to either copy it back into System32 or copy it into the application directory whenever they want to use it in their own applications, because Windows won't search the install directory under ProgramFiles when the application tries to load the DLL. I've been unable to find any Microsoft documentation discussing this issue, so if System32 shouldn't be used then where should shared DLLs be installed?

  • Sorting SQL query results in Java

    Firstly my apologies for putting some large text here. Below is the result by executing SQL query in Java but I want it to short it out using timestamp. For eg.

  • Why is BigDecimal.equals specified to compare both value and scale individually?

    - by bacar
    This is not a question about how to compare two BigDecimal objects - I know that you can use compareTo instead of equals to do that, since equals is documented as: Unlike compareTo, this method considers two BigDecimal objects equal only if they are equal in value and scale (thus 2.0 is not equal to 2.00 when compared by this method). The question is: why has the equals been specified in this seemingly counter-intuitive manner? That is, why is it important to be able to distinguish between 2.0 and 2.00? It seems likely that there must be a reason for this, since the Comparable documentation, which specifies the compareTo method, states: It is strongly recommended (though not required) that natural orderings be consistent with equals I imagine there must be a good reason for ignoring this recommendation.

  • Need new method for linking to native mapping from mobile web app

    - by Carter
    My mobile web apps use a map button which automatically starts the mapping features of Android and iPhone by simply linking to http://maps.google.com/maps?q=New+York. iOs 6 comes out, the links stop working, because Apple wants us to use "maps.APPLE.com". Turns out ANYTHING you send to "maps.apple.com" gets forwarded to "maps.google.com". So now I have to specially detect iOs 6 and swap out links just so Apple can forward everything back to Google anyway. Is there a clean way to open the device/native mapping app from a mobile web app that works on Android, iOs 6, and iOs pre-6, since iOs 6 nerfed it? Recently updated documentation on Apple dev site... http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/MapLinks.html#//apple_ref/doc/uid/TP40007894-SW1 Both these links go to the same place http://maps.google.com/maps?q=New+York http://maps.apple.com/maps?q=New+York

  • Cocoa Interface Builder object initialization

    - by Stanley
    Base on the documentation and sample code that I have gone through, I got an impression that when a class defined in xcode is read into and configured in Interface Builder, an object based on the class is effectively created and stored in an xib or nib file. So the object is ready to be used when the corresponding application is launched. Alternatively, for classes that have not been handled by Interface Builder, code such as the "new" statements have to be written in xcode explicitly in order for the associated objects to be created and used. It will be very nice to have people who are more knowledgable than me to confirm or to correct my very naive understanding of Interface Builder ...
