  • scripsharp reference web service / strongly type to results model

    - by user175528
    With scriptsharp (script#) is it possible to get strong typing when calling a service defined in my web app? The only way I can see is to: 1 - use linked / shared files to shadow copy my results classes / domain models across into my script# lib 2 - replicate my model across in the script# lib and use automapper to validate? 3 - use some .tt to code gen? also, even if I can do this, how do I get around the auto camel-casing script# does, when my service result (asmx) wont do this? (so my JSON response will comback as UserMessage, script# will have changed that to userMessage) basically, what I am looking to use script# to achieve is better compile time support against our domain model when calling and processing services in javascript, so something like this: Scriptlet public static class MyScriptlet { public static void Main() { MyService.Service1("hello", ProcessResponse);} public static void ProcessResponse(MyService.Service1ResponseData resp) { jQuery.Select('#Message').Text(resp.UserMessage); jQuery.Select('#Detail').Text(resp.UserDetail); } Service (in our web app) public class MyService { public class Service1ResponseData { public string UserMessage {get;set;} public string UserDetail {get;set;} } public Service1ResponseData Service1(string user) { return new Service1ResponseData() { UserMessage:"hi",UserDetail:"some text"}; } }

  • ajax error when calling from javascript

    - by vikitor
    Hi, I' still newby to this so I'll try to explain what I'm doing. Basically what I want is to load a dropdownlist depending on the value of a previous one, and I want it to load the data and appear when the other one is changed. This is the code I've written in my controller: public ActionResult GetClassesSearch(bool ajax, string phylumID, string kingdom){ IList<TaxClass> lists = null; int _phylumID = int.Parse(phylumID); int _kingdom = int.Parse(kingdom); lists = _taxon.getClassByPhylumSearch(_phylumID, _kingdom); return Json(lists); } and this is how I call the method from the javascript function: function loadClasses(_phylum) { var phylum = _phylum.value; $.getJSON("/Suspension/GetClassesSearch", { ajax: true, classID: phylum, kingdom: kingdom }, }, function(data) { $('#sClass').attr("disabled", true); $('#sClass').selectOptions("-2"); $('#sClass').removeOption(/./); var values = ''; $('#sClass').addOption("-2", "-Select All-"); for (i = 0; i < data.length; i++) { $('#sClass').addOption(data[i].RecId, data[i].TaxonName); } $('#sClass').selectOptions("-2"); $('#sClass').removeAttr("disabled"); }); } I can't get it to work. Any tips? Thanks in advance

  • Uploadify and rails 3 authenticity tokens

    - by Ceilingfish
    Hi chaps, I'm trying to get a file upload progress bar working in a rails 3 app using uploadify (http://www.uploadify.com) and I'm stuck at authenticity tokens. My current uploadify config looks like <script type="text/javascript" charset="utf-8"> $(document).ready(function() { $("#zip_input").uploadify({ 'uploader': '/flash/uploadify.swf', 'script': $("#upload").attr('action'), 'scriptData': { 'format': 'json', 'authenticity_token': encodeURIComponent('<%= form_authenticity_token if protect_against_forgery? %>') }, 'fileDataName': "world[zip]", //'scriptAccess': 'always', // Incomment this, if for some reason it doesn't work 'auto': true, 'fileDesc': 'Zip files only', 'fileExt': '*.zip', 'width': 120, 'height': 24, 'cancelImg': '/images/cancel.png', 'onComplete': function(event, data) { $.getScript(location.href) }, // We assume that we can refresh the list by doing a js get on the current page 'displayData': 'speed' }); }); </script> But I am getting this response from rails: Started POST "/worlds" for 127.0.0.1 at 2010-04-22 12:39:44 ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken): Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.0ms) Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (6.6ms) Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (12.2ms) This appears to be because I'm not sending the authentication cookie along with the request. Does anyone know how I can get the values I should be sending there, and how I can make rails read it from HTTP POST rather than trying to find it as a cookie?

  • jqGrid - edit function never getting called

    I'm having a problem with JQGrid using ASP.NET MVC. I'm trying to follow this example (after you go to that link, over on the left side of the page please click Live Data Manipulation, then Edit Row), but my edit function is never getting called (i.e. it's never getting into the $("#bedata").click(function().

  • Objective-C object release and allocation timing

    - by ryanjm.mp
    The code for this question is too long to be of any use. But I'm pretty sure my problem has to do with releasing a class. I have a helper class, ConnectionHelper.h/.m, that handles a NSURLConnection for me. Basically, I give it the URL I want and it returns the data (it happens to do a quick json parse on it too). It has a delegate which I set to the calling class (in this case: DownloadViewController). When it finishes the download, it calls [delegate didFinishParseOf:objectName withDictionary:dictionary];. Then in DownloadViewController I release ConnectionHelper and alloc a new one in order to download the next object. My problem is, I do this once, and then it creates the connection for the second one, and then my program just crashes. After this call: [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyNever]; NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; Then I don't think any of the following methods are called: - (NSCachedURLResponse *)connection:(NSURLConnection *)connection willCacheResponse:(NSCachedURLResponse *)cachedResponse - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge So am I right in that I'm not releasing something? When I release it the first time, the dealloc function isn't being called. Is there a way I can "force" it to deallocate? Do I need to force it to? I didn't think it would matter since I allocating a new ConnectionHelper for the new call. How else would they overlap / conflict with each other? Thank you.

  • Is there a detailed description of optimizations in the Android build process?

    - by Daniel Lew
    I've been curious as to all the optimizations that go into the building of an .apk. I'm curious because of two things I've tried in the past to bring down the size of my .apk: I have had a few large json assets in projects before, as well as a static sqlite database. I tried bringing down the size of the apk by gzipping them before the build process, but the resulting size is exactly the same. I just today tried pngcrush on my /drawable/ folders. The resulting build was exactly the same size as before. I would think that perhaps #1 could be explained by the zip process, but simply zipping the /drawable/ folders in #2 result in different-sized files. Perhaps the build process runs something akin to pngcrush? Regardless, I was wondering if anyone knew where to find a detailed description of all the optimizations in the Android build process. I don't want to waste my time trying to optimize what is already automated, and also I think it'd help my understanding of the resulting apk. Does anyone know if this is documented anywhere?

  • Passing object(s) to a Controller Action

    - by Nicholas H
    I'm attempting to use jQuery to do a $.post() to an MVC controller action. Here's the jQuery calls: var _authTicket = { username: 'testingu', password: 'testingp' }; function DoPost() { var inputObj = { authTicket: _authTicket, dateRange: 'ThisWeek' }; $.post('/MyController/MyAction', inputObj, PostResult); } function PostResult(data) { alert(JSON.stringify(data)); } Here's the controller action: <HttpPost()> _ Function MyAction(ByVal authTicket As AuthTicket, ByVal dateRange As String) As ActionResult Dim u = ValidateUser(authTicket) If u Is Nothing Then Throw New Exception("User not valid") ' etc.. End Function The problem is, MyAction's "authTicket" parameter is all empty. The second "dateRange" parameter gets populated just fine. I'm pretty sure that the issue stems from jQuery turning the data into key/value pairs to POST to the action. MVC must not understand the format, at least when it's an object with it's own properties. The name/value pair format that jQuery is converting to is like: authTicket[username] = "testingu" authTicket[password] = "testingp" Which in turn gets made into x-www-form-urlencoded'd data: authTicket%5Busername%5D=testingu &authTicket%5Bpassword%5D=testingp I guess I could always have "username" and "password" properties in my actions, but that seems wrong to me. Any help would be appreciated.

  • ASP.NET MVC and WCF

    - by Michael Stum
    I'm working my way into MVC at the moment, but on my "To learn at some point" list, I also have WCF. I just wonder if WCF is something that should/could be used in an MVC Application or not? The Background is that I want a Desktop Application (.NET 3.5, WPF) interact with my MVC Web Site, and I wonder what the best way to transfer data between the two is. Should I just use special Views/have the controllers return JSON or XML (using the ContentResult)? And maybe even more important, for the other way round, could I just call special controllers? Not sure how Authorization would work in such a context. I can either use Windows Authentication or (if the Site is running forms authentication) have the user store his/her credentials in the application, but I would then essentially create a HTTP Client in my Application. So while MVC = Application seems really easy, Application = MVC does seem to be somewhat tricky and a possible use for WCF? I'm not trying to brute-force WCF in this, but I just wonder if there is indeed a good use case for WCF in an MVC application.

  • What is the correct way to pass an object to WebApi RC controller

    - by Diver Dan
    I have a webapi project running rc I have a very basic controlller like [System.Web.Http.HttpPost] public void Update(Business business) { //if (business.Id == Guid.Empty) //{ // throw new HttpResponseException("Business ID not provided", HttpStatusCode.BadRequest); //} _repository.Update(business); //if (!isUpdated) //{ // throw new HttpResponseException("Business not found", HttpStatusCode.NotFound); //} } I found an example using HttpClient however it doesnt work with rc using (var client = new HttpClient()) { try { string url = string.Format("{0}{1}", ConfigurationManager.AppSettings["ApiBaseUrl"].ToString(),apiMethod); HttpRequestMessage request = new HttpRequestMessage(); MediaTypeFormatter[] formatter = new MediaTypeFormatter[] { new JsonMediaTypeFormatter() }; var content = request.CreateContent<Business>( business, MediaTypeHeaderValue.Parse("application/json"), formatter, new FormatterSelector()); HttpResponseMessage response = client.PostAsync(url, content).Result; return response.Content.ToString(); } catch (Exception ex) { return null; } } I get an error Method not found: 'Void System.Net.Http.Headers.HttpHeaders.AddWithoutValidation(System.String, System.String)'. Passing the data from jquery is a piece of cake however I need call the api from code behind vs client side. Can someone point me in the right direction for calling the webapi? Thank you

  • How does GMail implement Comet?

    - by Morgan Cheng
    With the help of HttpWatch, I tried to figure out how GMail implement Comet. I Login in GMail with two account, one in IE and the other in Firefox. Chatting in GTalk in GMail with some magic words like "WASSUP". Then, I logoff both GMail accounts, filter any http content without "WASSUP" string. The result shows which HTTP request is the streaming channel. (Note: I have to logoff. Otherwise, never-ending HTTP would not show content in HttpWatch.) The result is interesting. The URL for stream channel is like: https://mail/channel/bind?VER=8&at=xn3j33vcvk39lkfq..... There is no surprise that GMail do Comet in IE with IFRAME. The Http content starts with " Originally, I guessed that GMail do Comet in Firefox with multipart XmlHttpRequest. To my surprise, the response header doesn't have "multipart/x-mixed-replace" header. The response headers are as below: HTTP/1.1 200 OK Content-Type: text/plain; charset=utf-8 Cache-Control: no-cache, no-store, max-age=0, must-revalidate Pragma: no-cache Expires: Fri, 01 Jan 1990 00:00:00 GMT Date: Sat, 20 Mar 2010 01:52:39 GMT X-Frame-Options: ALLOWALL Transfer-Encoding: chunked X-Content-Type-Options: nosniff Server: GSE X-XSS-Protection: 0 Unfortunately, the HttpWatch doesn't tell whether a HTTP request is from XmlHttpRequest or not. The content is not HTML but JSON. It looks like a response for XHR, but that would not work for Comet without multipart/x-mixed-replace, right? Is there any way else to figure out how GMail implement Comet? Thanks.

  • Web.Routing for the site root or homepage

    - by Aquinas
    I am doing some work with Web.Routing, using it to have friendly urls and nice Rest like interfaces to a site that is essentially rendered by a single IHttpHandler. There are no webforms, the handler generates all the html/json and writes it as part of process request. This works well for things like /Sites/Accounting for example, but I can't get it to work for the site root, i.e. '/'. I have tried registering a route with an empty string, with 'default.aspx' (which is the empty aspx file I keep in my root folder to play nice with cassini and iis). I set RouteExistingFiles to false explicitly, but whatever I do when hitting the root url it still opens default.axpx, which has no code it inherits from, and contains a simple h1 tag to show that I've hit it. I don't want to change the default file to redirect to a desired route, I just want the equivalent of a 'default' route that is applied when no other routes are found, similar to MVC. For reference, the previous version of the site didn't use Web.Routing, but had a handler referenced in the web.config that was perfectly capable of intercepting requests for the root or default.aspx. Specs: ASP.NET 3.5sp1, C#, no webforms, MVC or openrasta. Plain old IHttpHandlers.

  • PHP CURL Google Calendar using Private URL

    - by MooCow
    I'm trying to get an array of events from Google Calendar using the Private URL. I read the Google API document but I want to try doing this without using the ZEND library since I have no idea what the eventual server file structure is and avoid having other people edit the codes. I also did a search before posting and ran into the same condition where PHP CURL_EXEC returns false with the URL but I get a JSON file if the URL is open using a web browser. Since I'm using the Private URL, do I really need to authenticate against the Google server using ZEND? I'm trying to have PHP clean up the array before encoding it for Flash. $URL = <string of the private URL from Google Calendar> $ch = curl_init($URL); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $data = curl_exec($ch); curl_close($ch); $result = json_decode($data); print '<pre>'.var_export($data,1).'</pre>'; Screen output >>> false

  • How can i optimize this c# code?

    I have converted my Datatable to json string use the following method... public string GetJSONString(DataTable Dt) { string[] StrDc = new string[Dt.Columns.Count]; string HeadStr = string.Empty; for (int i = 0; i < Dt.Columns.Count; i++) { StrDc[i] = Dt.Columns[i].Caption; HeadStr += "\"" + StrDc[i] + "\" : \"" + StrDc[i] + i.ToString() + "¾" + "\","; } HeadStr = HeadStr.Substring(0, HeadStr.Length - 1); StringBuilder Sb = new StringBuilder(); Sb.Append("{\"" + Dt.TableName + "\" : ["); for (int i = 0; i < Dt.Rows.Count; i++) { string TempStr = HeadStr; Sb.Append("{"); for (int j = 0; j < Dt.Columns.Count; j++) { if (Dt.Rows[i][j].ToString().Contains("'") == true) { Dt.Rows[i][j] = Dt.Rows[i][j].ToString().Replace("'", ""); } TempStr = TempStr.Replace(Dt.Columns[j] + j.ToString() + "¾", Dt.Rows[i][j].ToString()); } Sb.Append(TempStr + "},"); } Sb = new StringBuilder(Sb.ToString().Substring(0, Sb.ToString().Length - 1)); Sb.Append("]}"); return Sb.ToString(); } Is this fair enough or still there is margin for optimization to make it execute faster.... Any suggestion...

  • Authentication problem with Wufoo

    - by fudgey
    I set up a Wufoo form with admin only portions that will only show up if I am logged in. I read through the Wufoo API documentation and I can get the authenication to work, but when I try to access the form after I authenticate, it says I need to authenticate. This is what I have so far (subdomain, api key & form id changed) <?php error_reporting(E_ALL); ini_set('display_errors', 1); $curl1 = curl_init('http://fishbowl.wufoo.com/api/v3/users.xml'); curl_setopt($curl1, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl1, CURLOPT_USERPWD, 'AOI6-LFKL-VM1Q-IEX9:footastic'); curl_setopt($curl1, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($curl1, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl1, CURLOPT_FOLLOWLOCATION, false); curl_setopt($curl1, CURLOPT_USERAGENT, 'Wufoo Sample Code'); $response = curl_exec($curl1); $resultStatus = curl_getinfo($curl1); if($resultStatus['http_code'] == 200) { echo 'success!<br>'; } else { echo 'Call Failed '.print_r($resultStatus); } $curl2 = curl_init("http://fishbowl.wufoo.com/api/v3/forms/w7x1p5/entries.json"); curl_setopt($curl2, CURLOPT_HEADER, 0); curl_setopt($curl2, CURLOPT_RETURNTRANSFER, 1); $response = curl_exec($curl2); curl_close ($curl2); echo $response; curl_close($curl1); ?> It doesn't matter if I close $curl1 before or after I call $curl2, I get the same message on my screen: success! You must authenticate to get at the goodies. and I know the api, subdomain and form id are all correct. And one last bonus question... can I do all of this using Ajax instead? - the page I will be displaying the form on will already be limited to admin access, so exposing the API shouldn't matter.

  • How to serialize a Bundle?

    - by hermo
    I'd like to serialize a Bundle object, but can't seem to find a simple way of doing it. Using Parcel doesn't seem like an option, since I want to store the serialized data to file. Any ideas on ways to do this? The reason I want this is to save and restore the state of my activity, also when it's killed by the user. I already create a Bundle with the state I want to save in onSaveInstanceState. But android only keeps this Bundle when the activity is killed by the SYSTEM. When the user kills the activity, I need to store it myself. Hence i'd like to serialize and store it to file. Of course, if you have any other way of accomplishing the same thing, i'd be thankful for that too. Edit: I decided to encode my state as a JSONObject instead of a Bundle. The JSON object can then be put in a Bundle as a Serializable, or stored to file. Probably not the most efficient way, but it's simple, and it seems to work ok.

  • Variant datatype library for C

    - by Joey Adams
    Is there a decent open-source C library for storing and manipulating dynamically-typed variables (a.k.a. variants)? I'm primarily interested in atomic values (int8, int16, int32, uint, strings, blobs, etc.), while JSON-style arrays and objects as well as custom objects would also be nice. A major case where such a library would be useful is in working with SQL databases. The most obvious feature of such a library would be a single type for all supported values, e.g.: struct Variant { enum Type type; union { int8_t int8_; int16_t int16_; // ... }; }; Other features might include converting Variant objects to/from C structures (using a binding table), converting values to/from strings, and integration with an existing database library such as SQLite. Note: I do not believe this is question is a duplicate of http://stackoverflow.com/questions/649649/any-library-for-generic-datatypes-in-c , which refers to "queues, trees, maps, lists". What I'm talking about focuses more on making working with SQL databases roughly as smooth as working with them in interpreted languages.

  • decimal.TryParse() drops leading "1"

    - by Martin Harris
    Short and sweet version: On one machine out of around a hundred test machines decimal.TryParse() is converting "1.01" to 0.01 Okay, this is going to sound crazy but bare with me... We have a client applications that communicates with a webservice through JSON, and that service returns a decimal value as a string so we store it as a string in our model object: [DataMember(Name = "value")] public string Value { get; set; } When we display that value on screen it is formatted to a specific number of decimal places. So the process we use is string - decimal then decimal - string. The application is currently undergoing final testing and is running on more than 100 machines, where this all works fine. However on one machine if the decimal value has a leading '1' then it is replaced by a zero. I added simple logging to the code so it looks like this: Log("Original string value: {0}", value); decimal val; if (decimal.TryParse(value, out val)) { Log("Parsed decimal value: {0}", val); string output = val.ToString(format, CultureInfo.InvariantCulture.NumberFormat); Log("Formatted string value: {0}", output); return output; } On my machine - any every other client machine - the logfile output is: Original string value: 1.010000 Parsed decimal value: 1.010000 Formatted string value: 1.01 On the defective machine the output is: Original string value: 1.010000 Parsed decimal value: 0.010000 Formatted string value: 0.01 So it would appear that the decimal.TryParse method is at fault. Things we've tried: Uninstalling and reinstalling the client application Uninstalling and reinstalling .net 3.5 sp1 Comparing the defective machine's regional settings for numbers (using English (United Kingdom)) to those of a working machine - no differences. Has anyone seen anything like this or has any suggestions? I'm quickly running out of ideas... While I was typing this some more info came in: Passing a string value of "10000" to Convert.ToInt32() returns 0, so that also seems to drop the leading 1.

  • Secure Password Storage and Transfer

    - by Andras Zoltan
    I'm developing a new user store for my organisation and am now tackling password storage. The concepts of salting, HMAC etc are all fine with me - and want to store the users' passwords either salted and hashed, HMAC hashed, or HMAC salted and hashed - not sure what the best way will be - but in theory it won't matter as it will be able to change over time if required. I want to have an XML & JSON service that can act as a Security Token Service for client-side apps. I've already developed one for another system, which requires that the client double-encrypts a clear-text password using SHA1 first and then HMACSHA1 using a 128 unique key (or nonce) supplied by the server for that session only. I'd like to repeat this technique for the new system - upgrading the algo to SHA256 (chosen since implementations are readily available for all aforementioned platforms - and it's much stronger than SHA1) - but there is a problem. If I'm storing the password as a salted hash in the user-store, the client will need to be sent that salt in order to construct the correct hash before being HMACd with the unique session key. This would completely go against the point of using a salt in the first place. Equally, if I don't use salt for password storage, but instead use HMAC, it's still the same problem. At the moment, the only solution I can see is to use naked SHA256 hashing for the password in the user store, so that I can then use this as a starting point on both the server and the client for a more secure salted/hmacd password transfer for the web service. This still leaves the user store vulnerable to a dictionary attack were it ever to be accessed; and however unlikely that might be - assuming it will never happen simply doesn't sit well with me. Greatly appreciate any input.

  • structured vs. unstructured data in db

    - by Igor
    the question is one of design. i'm gathering a big chunk of performance data with lots of key-value pairs. pretty much everything in /proc/cpuinfo, /proc/meminfo/, /proc/loadavg, plus a bunch of other stuff, from several hundred hosts. right now, i just need to display the latest chunk of data in my UI. i will probably end up doing some analysis of the data gathered to figure out performance problems down the road, but this is a new application so i'm not sure what exactly i'm looking for performance-wise just yet. i could structure the data in the db -- have a column for each key i'm gathering. the table would end up being O(100) columns wide, it would be a pain to put into the db, i would have to add new columns if i start gathering a new stat. but it would be easy to sort/analyze the data just using SQL. or i could just dump my unstructured data blob into the table. maybe three columns -- host id, timestamp, and a serialized version of my array, probably using JSON in a TEXT field. which should I do? am i going to be sorry if i go with the unstructured approach? when doing analysis, should i just convert the fields i'm interested in and create a new, more structured table? what are the trade-offs i'm missing here?

    i have something similar to the following... used a python script to JSON to populate. <ul> <li id="p1" class="x">val1 <img id="ip1" class="redx" src="redx.gif"/></li> <li id="p2" class="x">val2 <img id="ip2" class="redx" src="redx.gif"/></li> <li id="p3" class="x">val3 <img id="ip3" class="redx" src="redx.gif"/></li> <li id="p4" class="x">val4 <img id="ip4" class="redx" src="redx.gif"/></li> </ul> I'd like some jquery to... when click the red x image.. to hide the whole LI cell it is in. I have tried a few things but ... to no avail. EDIT: All in all.. this doesnt seem to trigger ... this seems like a fundamental issue. $(function(){ function removeli() { alert("got here" + this.id); } $("redx").click(removeli); }); Any ideas on the final jquery code to accomplish this?

  • WCF REST with jQuery AJAX - removing/working around same origin policy

    - by csauve
    So I'm trying to create a C# WCF REST service that is called by jQuery. I've discovered that jQuery requires that AJAX calls are made under the same origin policy. I have a few questions for how I might proceed. I am already aware of; 1. The hacky solution of JSONP with a server callback 2. The way too much server overhead of having a cross-domain proxy. 3. Using Flash in the browser to make the call and setting up crossdomain.xml at my WCF server root. I'd rather not use these because; 1. I don't want to use JSON, or at least I don't want to be restricted to using it 2. I would like to separate the server that serves static pages from the one that serves application state. 3. Flash in this day in age is out of the question. What I'm thinking: is there anything like Flash's crossdomain.xml file that works for jQuery? Is this "same-origin" policy a part of jQuery or is it a restriction in specific browsers? If it's just a part of jQuery, maybe I'll try digging in the code to work around it.

  • jQuery1.4.2 $.ajax crashes IE6/7

    - by Kenny Eliasson
    Hello there! I'm having a really hard time debugging one of our latest reported bugs. The problem occurs "randomly", not on every page load, sometimes I can "click" around for a minute or two before IE6/7 crashes. By crash I mean that the IE-window shuts down and I get the option to send the crash info to Microsoft. In FF, Chrome, Safari, IE8 everything is working perfectly. What the page does is issuing 2 AJAX Jsonp calls and building some menus with the data returned. The data brought back can be from ~500b to approx. 35kb. The JSON is valid (else it wouldn't have loaded at all in FF etc), and as i told previous, it works for when navigating around the site soemtimes in IE6/7. I've tested to comment out the callbacks, still crashes. If I remove the $.ajax calls the page will work again. Whats strange is that if I downgrade to jQuery 1.3.2 everything works in all browsers including IE6/7. I've taken the crash-logs and looked at them in WinDbg and what happens seems to be a NULL POINTER reference. The last entries of the stack trace is as follows mshtml!CTreePos::SourceIndex+0x9 mshtml!CMarkup::InsertElementInternal+0x3a8 mshtml!CDoc::InsertElement+0x98 mshtml!CDocument::get_implementation+0x144 Anyone having a clue what could cause this?

  • Is there any framework for rich web clients on top of html/css?

    - by iamgopal
    Some RAD tools like openobject use rich web clients. I.e. their client side code reside inside the browser and they talk to the server via xml-rpc or json-rpc only and change the view accordingly, all the javascript and css are transferred only once. Such rich web clients would increase the productivity in enterprise class web application that have lots of processes and forms etc. I would like to use such a rich web client inside my own application. I tried to search but found only openerp-web, which is tightly integrated to its server. Is there any other rich web client framework available? if not, is there any design detail I can look into to create my own? Thanks. Edit: Browser is a client which uses http and similar protocols to talks to web server which serve pages that the client displays. Rich web client is a client which sits on top of Browser which talks to the server, send data, receive data and information about How to update the view etc and do it. Similar to Vaadin, such rich web client will eliminate any code requirement on client side and and all the coding will be done on server side. Belows are such thin clients. pjax ( jquery ) vaadin ( java ) openobject web client ( python ) nagare ( python ) seaside ( smalltalk ) p4a ( php ) this are all such clients that once properly setup will allow to code on only on sever and still provide great ajax like experience.

  • What is the best way to process XML sent to WCF 3.5

    - by CRM Junkie
    I have to develop a WCF application in 3.5. The input will be sent in the form of XML and the response would be sent in the form of XML as well. A ASP.NET application will be consuming the WCF and sending/receiving data in XML format. Now, as per my understanding, when consuming WCF from an ASP.NET application, we just add a reference to the service, create an object of the service, pack all the necessary data(Data Members in WCF) into the input object (object of the Data Contract) and call the necessary function. It happens that the ASP.NET application is being developed by a separate party and they are hell bent on receiving and sending data in XML format. What I can perceive from this is that the WCF will take the XML string (a single Data Member string type) as input and send out a XML string (again a single Data Member string type) as output. I have created WCF applications earlier where requests and responses were sent out in XML/JSON format when it was consumed by jQuery ajax calls. In those cases, the XML tags were automatically mapped to the different Data Members defined. What approach should I take in this case? Should I just take a string as input (basically the XML string) or is there any way WCF/.NET 3.5 will automatically map the XML tags with the Data Members for requests and responses and I would not need to parse the XML string separately?
