  • sproutcore - todos tutorial, addbutton not responding in firefox

    - by kristian nissen
    I'm testing the sproutcore todo's tutorial and I have checked the code in step-5 and it's identical to my code at least as far as I can see, but the addButton is not responding to click events. addTask: function () { var task; task = Sinatra.store.createRecord(Sinatra.Task, { 'description': 'New Task', 'isDone': false, 'priority': 1 }); this.selectObject(task); this.invokeLater(function () { var contentIndex = this.indexOf(task); var list = Sinatra.mainPage.getPath('mainPane.middleView.contentView') var listItem = list.itemViewForContentIndex(contentIndex); listItem.beginEditing(); }); return YES; and in the main: addButton: SC.ButtonView.design({ layout: { centerY: 0, height: 24, right: 12, width: 100 }, title: 'Add Task', target: 'Sinatra.tasksController', action: 'addTask' }), I can't see the problem, please help. (I have only tested this in firefox on kubuntu)

  • Only perform jquery effects/operations on certain pages

    - by Galen
    Up until now i've been dropping all my jquery code right inside the document.ready function. I'm thinking that for certain situations this isnt the best way to go. for example: If i want an animation to perform when a certain page loads what is the best way to go about that. $(document).ready(function() { $("#element_1").fadeIn(); $("#element_2").delay('100').fadeIn(); $("#element_3").delay('200').fadeIn(); }); If this is right inside of document.ready then every time ANY page loads it's going to check each line and look for that element. What is the best way to tell jquery to only perform a chunk of code on a certain page to avoid this issue.

  • Catch database exception in Kohana

    - by danilo
    I'm using Kohana 2. I would like to catch a database exception to prevent an error page when no connection to the server can be established. The error displayed is system/libraries/drivers/Database/Mysql.php [61]: mysql_connect() [function.mysql-connect]: Lost connection to MySQL server at 'reading initial communication packet', system error: 110 The database server is not reachable at all at this point. I'm doing this from a model. I tried both public function __construct() { // load database library into $this->db try { parent::__construct(); } catch (Exception $e) { die('Database error occured'); } } as well as try { $hoststatus = $this->db->query('SELECT x FROM y WHERE z;'); } catch (Exception $e) { die('Database error occured'); } ...but none of them seemed to work. It seems as if no exception gets passed on from the main model. Is there another way to catch the database error and use my own error handling?

  • Avoiding exceptions when uploading files in laravel

    - by occam98
    I've got a file upload field (attachment1) in a form that may or may not have a file uploaded in it when I process the form in laravel. When I'm trying to process the page, this line generates an exception: Input::upload('attachment1',path('storage').'attachments/'.$name); Here is the text of the exception: Message: Call to a member function move() on a non-object it seems that I need to check in advance to see if 'attachment1' has a file, and I found that the function Input::has_file('attachment1') is supposed to tell me whether or not 'attachment1' has a file, but even when I submit an empty form, it returns true. Also, from reading documentation, it seems that Input::upload is supposed to just return false when trying to upload a non-existant file, so why does it produce this exception instead, and how can I fix it?

  • How do I replace custom "tags" in a string?

    - by Fake Code Monkey Rashid
    Given the following: $foo = "Yo [user Cobb] I heard you like dreams so I put a dream in yo dream in yo dream so you can dream while you dream while you dream." I'd like to do this: $foo = bar($foo); echo $foo; And get something like this: Yo Cobb I heard you like dreams so I put a dream in yo dream in yo dream so you can dream while you dream while you dream. I'm unsure of how the bar function should work. I think this is doable with regular expressions but I personally find those hard to understand. Using the strpos function is another method but I wonder if there is a better solution. Pseudocode is fine but actual code will be appreciated.

  • jsTree causes that links on whole page are broken

    - by niao
    Greetings, I have the following problem. In my asp.net mvc page (which is a partial view) I create an instance of jsTree as follows: <script type="text/javascript"> $(function() { $("#industries").tree({ callback: { onselect: function(NODE, TREE_OBJ) { $("#SelectedIndustryROWGUID").val($(NODE).attr("id")); $("#resultMessage").append($(NODE).attr("rel")); } }, data: { type: "json", async: true, opts: { method: "GET", url: "/CreateMessage/GetIndustries/" } } }); }); this works fine but then, when I click on any link on the page, it does not work. The links are executed when I choose "open in new tab" option from context menu. Can someone please help me with this?

  • Convert C# event handling to VB.NET

    - by Quandary
    Question: The following C# code: public event RemoteAPI.NotifyCallback Notify { add { s_notify = value; } remove { Console.WriteLine("TODO : Notify remove."); } } How do I convert this to VB.NET ?

    BElow is the function that selects related product of a single product. I wanted it to work in such a way that if there are no related products other random products will be added to the array.

  • _heapwalk reports _HEAPBADNODE, causes breakpoint or loops endlessly

    - by Stefan Hubert
    I use _heapwalk to gather statistics about the Process' standard heap. Under certain circumstances i observe unexpected behaviours like: _HEAPBADNODE is returned some breakpoint is triggered inside _heapwalk, telling me the heap might got corrupted access violation inside _heapWalk. I saw different behaviours on different Computers. On one Windows XP 32 bit machine everything looked fine, whereas on two Windows XP 64 bit machines i saw the mentioned symptoms. I saw this behaviour only if LowFragmentationHeap was enabled. I played around a bit. I walked the heap several times right one after another inside my program. First time doing nothing in between the subsequent calls to _heapWalk (everything fine). Then again, this time doing some stuff (for gathering statistics) in between two subsequent calls to _heapWalk. Depending upon what I did there, I sometimes got the described symptoms. Here finally a question: What exactly is safe and what is not safe to do in between two subsequent calls to _heapWalk during a complete heap walk run? Naturally, i shall not manipulate the heap. Therefore i doublechecked that i don't call new and delete. However, my observation is that function calls with some parameter passing causes my heap walk run to fail already. I subsequently added function calls and increasing number of parameters passed to these. My feeling was two function calls with two paramters being passed did not work anymore. However I would like to know why. Any ideas why this does not happen on some machines? Any ideas why this only happens if LowFragmentationHeap is enabled? Sample Code finally: #include <malloc.h> void staticMethodB( int a, int b ) { } void staticMethodA( int a, int b, int c) { staticMethodB( 3, 6); return; } ... _HEAPINFO hinfo; hinfo._pentry = NULL; while( ( heapstatus = _heapwalk( &hinfo ) ) == _HEAPOK ) { //doing nothing here works fine //however if i call functions here with parameters, this causes //_HEAPBADNODE or something else staticMethodA( 3,4,5); } switch( heapstatus ) { ... case _HEAPBADNODE: assert( false ); /*ERROR - bad node in heap */ break; ...

  • Google Website Optimizer - Multi Variant Testing - Make a specific page a test page for two experime

    - by wawawowo
    Im having a little issue with setting up Multi Variant Tests in Google Website Optimizer. I wish to have two tests. One being which is a header banner which appears on every page and the conversion for example would be if the visitor lands on the contact us page. This was very easy to set up. However when I intend to add another test, again this will be on a element which appears on every page and the conversion page is if the visitor lands on the checkout page. But I am now having problems installing the control script. I get the error: Expected to find: }(function(){var k='0651116117',d=docum Found on line 7: (function(){var k='2666211118',d=docum Im assuming I have this error because I now have two control scripts in the header - one for each experiment. However I cannot combine each variation into just one experiment because each one is different and has a different conversion page? Please advise, thanks.

  • How do you implement file drag-and-drop upload in Google Chrome?

    - by Chris R
    I've found several tutorials online about implementing file drag/drop with Firefox 3.6 (they involve using a FileReader object to get the file binary data). However, I cannot create a FileReader object in Chrome on Windows or Mac. Does anyone know what the API is to read and manipulate data from a drag-and-dropped file in Chrome? If I can get the binary data of the file, I already have the rest of the code to perform the upload. Note: I've also tried using the getAsBinary() function call on the file object of the drag event (event.dataTransfer.file) but I believe that is a Mozilla-specific function and not implemented in Chrome. Also, I'm not interested in a solution using google gears or one that requires a user to select files from a dialog. I'm specifically trying to implement a drag-and-drop file upload.

  • C++ Win32 Unhandled Exception Handler

    - by uray
    currently I used SetUnhandledExceptionFilter() to provide callback to get information when an unhandled exception was occurred, that callback will provides me with EXCEPTION_RECORD which provides ExceptionAddress. [1]what is actually ExceptionAddress is? does it the address of function / code that gives exception, or the memory address that some function tried to access? [2]is there any better mechanism that could give me better information when unhandled exception occured? (I can't use debug mode or add any code that affect runtime performance, since crash is rare and only on release build when code run as fast as possible) [3]is there any way for me to get several callstack address when unhandled exception occured. [4]suppose ExceptionAddress has address A, and I have DLL X loaded and executed at base address A-x, and some other DLL Y at A+y, is it good to assume that crash was PROBABLY caused by code on DLL X?

  • How can I hide tracing code in Visual Studio IDE C# ?

    - by Mark
    As I'm starting to put more tracing in my code, i'm realizing it adds a lot of clutter. I know Visual Studio allows you to hide and reveal code, however, i'd like to be able group code into "tracing" code and then hide it and reveal at will as i'm reading the code. I suppose it could do this either per file or per class or per function. Is there any way to do this? What do you guys do? Adding some clarification The hide current feature kind of allows you to do this except that when the code is hidden, you can't tell if its tracing or not. You also can't say "hide all tracing code" and "reveal all tracing code" which is useful when reading a function depending on what you are trying to do.

  • how do arguments work with dojo.connect?

    - by sprugman
    I've read the docs, but I must be missing something. I've got a grid, I want to connect to the event that fires when the column headers are clicked for sorting, thus: dojo.addOnLoad(function(){ var grid = dijit.byId("grid"); dojo.connect(grid, "setSortInfo", 'afterSort'); }); function afterSort() { console.info('after sort'); } That works fine as far as it goes. I know the setSortInfo method has an argument which is the column number. How do I get that value? I've tried putting a parameter in the sig for afterSort to no avail. The docs say "the method receives the same arguments as the event", but where are they???

  • How Can I Disable CRL Checks For A Windows 2008 App Using WinHTTP?

    - by Mike B
    I've got a Windows 2008 server with an app that uses WinHTTP for SSL sessions. The server is isolated from the internet but still tries to connect to CRL distribution points, which leads to some timeouts. Since the server has no access to the internet whatsoever, I'd like to disable CRL checks. I had a similar issue on a Windows 2003 server and resolved it by adjusting the following registry keys: HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Http/Parameters/SslBindiongInfo/0.0.0.0:443/DefaultSslCertCheckMode (DWORD=1) HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Rasman/PPP/EAP/13/NoRevocationCheck (DWORD = 1) HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Rasman/PPP/EAP/13/NoRootRevocationCheck (DWORD = 1) That doesn't seem to be working in 2008. I've also tried disabling the CRL check from IE under Tools Internet Options Advanced. Is there anything else I can try here?

  • How would you organize this Javascript?

    - by Anurag
    How do you usually organize complex web applications that are extremely rich on the client side. I have created a contrived example to indicate the kind of mess it's easy to get into if things are not managed well for big apps. Feel free to modify/extend this example as you wish - http://jsfiddle.net/NHyLC/1/ The example basically mirrors part of the comment posting on SO, and follows the following rules: Must have 15 characters minimum, after multiple spaces are trimmed out to one. If Add Comment is clicked, but the size is less than 15 after removing multiple spaces, then show a popup with the error. Indicate amount of characters remaining and summarize with color coding. Gray indicates a small comment, brown indicates a medium comment, orange a large comment, and red a comment overflow. One comment can only be submitted every 15 seconds. If comment is submitted too soon, show a popup with appropriate error message. A couple of issues I noticed with this example. This should ideally be a widget or some sort of packaged functionality. Things like a comment per 15 seconds, and minimum 15 character comment belong to some application wide policies rather than being embedded inside each widget. Too many hard-coded values. No code organization. Model, Views, Controllers are all bundled together. Not that MVC is the only approach for organizing rich client side web applications, but there is none in this example. How would you go about cleaning this up? Applying a little MVC/MVP along the way? Here's some of the relevant functions, but it will make more sense if you saw the entire code on jsfiddle: /** * Handle comment change. * Update character count. * Indicate progress */ function handleCommentUpdate(comment) { var status = $('.comment-status'); status.text(getStatusText(comment)); status.removeClass('mild spicy hot sizzling'); status.addClass(getStatusClass(comment)); } /** * Is the comment valid for submission */ function commentSubmittable(comment) { var notTooSoon = !isTooSoon(); var notEmpty = !isEmpty(comment); var hasEnoughCharacters = !isTooShort(comment); return notTooSoon && notEmpty && hasEnoughCharacters; } // submit comment $('.add-comment').click(function() { var comment = $('.comment-box').val(); // submit comment, fake ajax call if(commentSubmittable(comment)) { .. } // show a popup if comment is mostly spaces if(isTooShort(comment)) { if(comment.length < 15) { // blink status message } else { popup("Comment must be at least 15 characters in length."); } } // show a popup is comment submitted too soon else if(isTooSoon()) { popup("Only 1 comment allowed per 15 seconds."); } });

  • createChildren Called Before Component's MXML Bracket Logic Is Evaluated

    - by Nalandial
    I have the following MXML: <mx:Script> var someBoolean:Boolean = determineSomeCondition(); </mx:Script> .... <foo:MyComponent somePropertyExpectingIDataRenderer="{ someBoolean ? new Component1ThatImplementsIDataRenderer() : new Component2ThatImplementsIDataRenderer() }"> </foo:MyComponent> I have also overridden the createChildren() function: override protected function createChildren():void { super.createChildren(); //do something with somePropertyExpectingIDataRenderer } My problem is: createChildren() is being called before the squiggly bracket logic is being evaluated, so in createChildren(), somePropertyExpectingIDataRenderer is null. However if I pass the component via MXML like this: <foo:MyComponent> <bar:somePropertyExpectingIDataRenderer> <baz:Component1ThatImplementsIDataRenderer/> </bar:somePropertyExpectingIDataRenderer> </foo:MyComponent> Then when createChildren() is called, that same property isn't null. Is this supposed to happen and if so, what other workarounds should I consider?

  • Redirect Output of Capistrano

    - by Eric Lubow
    I have a Capistrano deploy file (Capfile) that is rather large, contains a few namespaces and generally has a lot of information already in it. My ultimate goal is, using the Tinder gem, paste the output of the entire deployment into Campfire. I have Tinder setup properly already. I looked into using the Capistrano capture method, but that only works for the first host. Additionally that would be a lot of work to go through and add something like: output << capture 'foocommand' Specifically, I am looking to capture the output of any deployment from that file into a variable (in addition to putting it to STDOUT so I can see it), then pass that output in the variable into a function called notify_campfire. Since the notify_campfire function is getting called at the end of a task (every task regardless of the namespace), it should have the task name available to it and the output (which is stored in that output variable). Any thoughts on how to accomplish this would be greatly appreciated.

  • How do you get the glyph for a character encoded as '&#333;' from a utf-8 encoded database field usi

    - by AE
    I have a MySQL database table with a collation of 'utf8_general_ci' and the value in the field is: x & #299; bán yá wén (without the spaces). When this is converted (for example by StackOverflow's editor) it looks like this: xī bán yá wén where the second character looks like a lower case i with a bar over the top. In PHP, what function converts the & #299 ; entity into the ī character? I've tried using html_entity_decode($str,ENT_COMPAT,'UTF-8'), however I get characters like the following: yÄ«n wén or zhÅ•ng wén I'm pretty sure there's something I don't understand about the decoding, which is why I'm using the wrong function. Can anyone shed some light on how to get the single character glyph that's represented by the entity & #299 and similar high-number characters above 255? Many thanks, AE
