  • jquery.ajax multiple data problem

    - by Guillaume P
    Hi, I've been trying to make this code work for the last 3 hours. I've tried about everytinh, but I'm still unable to get it to work. I only managed to send 1 data. When I use this code, I only manage to retrieve recaptcha_challenge_field. If I remove recaptcha_challenge_field, I retrieve recaptcha_response_field. However, I am unable to retrieve the two at the same time. challengeField = $("#recaptcha_challenge_field").val(); responseField = $("#recaptcha_response_field").val(); var html = $.ajax( { global: false, type: "POST", async: false, dataType: "html", data: "recaptcha_response_field=" + responseField + "&recaptcha_challenge_field=" + challengeField, url: "../ajax.recaptcha.php" }).responseText; if(html == "success") { $("#captchaStatus").html("Success. Submitting form."); return true; } else { $("#captchaStatus").html("Your captcha is incorrect. Please try again"); Recaptcha.reload(); return false; }

  • Is it possible to have CommandManager requery only specific WPF command instead of all?

    - by aoven
    I'm trying to implement a highly responsive UI for my MVVM application, so I've chosen to have all command handlers automatically execute in a BackgroundWorker so they don't block the UI. But at the same time, I don't want the user to be able to execute the same command while it is still executing in the background. The solution seems obvious: When Executed handler is invoked, have the CanExecute handler return false Start the BackgroundWorker async When BackgroundWorker finishes, have the CanExecute handler return true again. Problem is, I need to notify WPF after step 1 and again after step 3 that CanExecute has changed and that it should be required. I know I can do it by calling CommandManager.InvalidateRequerySuggested, but that causes CanExecute handlers of all other commands to be requeried as well. Having a lot of commands, that's not good. Is there a way to ask for requery of a specific command - i.e. the one that is currently being executed? TIA

  • Raise the time-out for a single webservice

    - by Carra
    My web configuration looks as follows: <system.web> <compilation debug="false"/> <httpRuntime executionTimeout="90"/> </system.web> This is fine for most webservices but one webservice has a query that is running a very long (5 minutes) time and will be stopped before it has finished. Is it possible to set the runtime to 5 minutes for this webservice alone? I've thought about running the database query async (fire and forget) but it doesn't seem possible with sybase/oracle through ODBC.

  • SmtpClient.SendAsync(); Not working on my new (64bit) computer.

    - by j-t-s
    Hi All, Okay, Only a couple weeks ago I had an old 32bit computer, but had to buy a new computer, which happens to be 64bit. I've rewritten the method that sends e-mails asynchonously and it just does not work. And does NOT throw any exceptions either. What gives? I have also tried the Async method code found iin MSDN, and the BlackWasp tutorial code, and MANY others. They're all the same! The only difference here seems to be the fact that I'm now on a 64bit computer. How can I get around this? Google/MSDN has been of zero help. Thanks

  • msxml domdocument stops working when I move to staging server

    - by blockhead
    I have some code that looks like this: Set xmlHttp = Server.CreateObject("MSXML2.ServerXMLHTTP") xmlHttp.Open "Get", myRSSfile, false xmlHttp.Send() myXML = xmlHttp.ResponseText Set xmlResponse = Server.CreateObject("MSXML2.DomDocument") xmlResponse.async = false xmlResponse.LoadXml(myXML) Set xmlHttp = Nothing Set objLst = xmlResponse.getElementsByTagName("item") Set xmlResponse = Nothing NoOfHeadlines = objLst.length - 1 Response.Write NoOfHeadlines This worked find on my development server. When I moved it over to a staging server (which I have no control over, and no nothing about), NoOfHeadlines returns 0. It seems obvious to me that DomDocument is not working the way its supposed to. Is this a version issue? How do I find out what version of DomDocument is on the staging server? Is there another possibility?

  • How can I perform a normal postback on an ASP.NET page with AJAX history enabled?

    - by Nick
    I have an ASP.NET 3.5 page with an update panel and history enabled. It works fine when I perform async postbacks but I get problems when I want to perform a normal postback. The page load happens fine for the normal postback but then I get asynchronous page loads from the script manager which load the ajax history in. If I could have the ajax history not loading for the times I want to perform a normal postback then everything would be fine. Is there anyway to do this?

  • how to lengthen the pause between the words with text-to-speech (pyTTS or SAPI5)

    - by Berry Tsakala
    Is it possible to extend the gap between spoken words when using text to speech with SAPI5 ? The problem is that esp. with some voices, the words are almost connected to each other, which makes the speech more difficult to understand. I'm using python and pyTTS module (on windows, since it's using SAPI) I tried to hook to the OnWord event and add a time.sleep() or tts.Pause(), but apparently even though all the events are caught, they are being processed only at the end of the spoken text, whether i'm using the sync or async flag. In this NON WORKING example, the sleep() method is executed only after the sentence is spoken: tts = pyTTS.Create() def f(x): tts.Pause() sleep(0.5) tts.Resume() tts.OnWord = f tts.Speak(text)

  • Asynchronous Processing in JBoss 6 ("Comet")

    - by chris_l
    edit: Retagged as tomcat, since this is really a question about the Tomcat embedded inside JBoss 6, rather than JBoss itself I have an extremely simple servlet, which works on Glassfish v3. It uses Servlet 3.0 Asynchronous Processing. Here's a simplified version (which doesn't do much): @WebServlet(asyncSupported=true) public class SimpleServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { final AsyncContext ac = request.startAsync(); ac.setTimeout(3000); } } On JBoss 6.0.0 (Milestone 2), I get the following Exception: java.lang.IllegalStateException: The servlet or filters that are being used by this request do not support async operation at org.apache.catalina.connector.Request.startAsync(Request.java:3096) at org.apache.catalina.connector.Request.startAsync(Request.java:3090) at org.apache.catalina.connector.RequestFacade.startAsync(RequestFacade.java:990) at playcomet.SimpleServlet.doGet(SimpleServlet.java:18) at javax.servlet.http.HttpServlet.service(HttpServlet.java:734) ... Do I have to do anything special to enable Asynchronous Processing in JBoss 6? Or do I need an additional deployment descriptor? ...

  • QGrid display default "loading" message when updating a table / on custom update

    - by JVXR
    I have a case where I need to update a jqgrid based on some search criteria which the user selects. I can get the data to update , but I would want the loading message to show while the new data is being fetched. Can someone please let me know how to get that working ? Current code follows var ob_gridContents = $.ajax( { url : '/DisplayObAnalysisResults.action?getCustomAnalysisResults', data : "portfolioCategory="+ $('#portfolioCategory').val() +"&subPortfolioCategory="+ $('#subPortfolioCategory').val() + "&subportfolio=" + $('#subportfolio').val(), async : false }).responseText; var ob_Grid = jQuery('#OBGrid')[0]; var ob_GridJsonContents = eval('(' + ob_gridContents + ')'); $('#ob_Grid').trigger("reloadGrid"); ob_Grid.addJSONData(ob_GridJsonContents); ob_Grid = null; ob_GridJsonContents = null; }

  • How can I use my own connection class with a strongly typed dataset?

    - by Maslow
    I have designed a class with sqlClient.SqlCommand wrappers to implement such functionality as automatic retries on timeout, Async (thread safety), error logging, and some sql server functions like WhoAmI. I've used some strongly typed datasets mainly for display purposes only, but I'd like to have the same database functionality that I use with my class. Is there an interface I can implement or a way to hook my command/connection class into the dataset at design or runtime? Or would I need to somehow write a wrapper for the dataset to implement these types of functions? if this is the only option could it be made generic to wrap anything that inherits from dataset?

  • Block until an event has completed.

    - by robUK
    Hello, gcc 4.4.2 c89 I have a function that has to run (config_relays). It make a call to a API function called set_relay, then the code has to wait before continuing until the event for set_relay event has completed. The set_relay is any Async call. i.e. void run_processes() { switch() { case EV_RELAY_SET: break; } } void config_relays() { set_relay(); /* Wait until EV_RELAY_SET has fired */ /* Cannot do init_relay until set_relay event has fired - has to block here */ init_relay(); } I guess I could put the init_relay() in the switch. However, that event is used for other things and not just for initializing the relay. I would really like to handle everything in the config_relays function. In C# you can do this by using autoreset. Does C have anything like that. Many thanks for any advice,

  • How to check when Shell32.Folder.CopyHere() is finished

    - by Jelle Capenberghs
    I need to unzip en zip some files in my application using Shell32. Right now, I use srcFolder.CopyHere(destFolder.Items()) to achieve this. However, my next line of code requires the newly made ZIP-file. But since the CopyHere method is Async, how can I check when it in finished? Right now I use a Thread.Sleep for around 500 ms which is enough for my computer to finish creating the ZIP file, but it's not good code imo. Any ideas? More info/code can be provided if necessary.

  • UITableView via NSFetchedResultsControllerDelegate, select first record by default?

    - by deafgreatdane
    I have a UITableView that gets populated from CoreData via a controller that implements NSFetchedResultsControllerDelegate. How can I have it automatically select the first row (and fire the tableView:didSelectRowAtIndexPath message)? The tableview is used for a variety of predicate queries, so I'm suspicious of solutions that work on the UIViewController lifecycle (viewDidLoad, etc), but I'm new to the platform, so I'm open. I've tried a variety of things, but I'm not sure where in the call stack to put it. I've tried calling cell.selected = true inside tableView:cellForRowAtIndex: method, but that just ends up turning the cell black (and doesn't fire the selected callback method) A tagent question, with all the delegating and core data protocols, does it imply asynchronous data fetch (multiple threads)? Or is the NSFetchedResultsController calling all its related methods in the same thread? Maybe I'm just scared that if it is async, there would be race conditions that would be tough to troubleshoot later.

  • jQuery Ajax works in Firefox, fails in IE when calling Controller action

    - by myaesubi
    Hello there, I'm making the following jQuery ajax call to an action in ASP.NET MVC. In Firefox the async request is sent to the action in the controller and everything works fine, but in IE no request is sent to the controller. Here is the ajax call and action controller signature: $.ajax({ cache: false, type: "GET", dataType: "json", contentType: "application/json; charset=utf-8", url: "/Fmz/AssignFmzToRegion", data: { fmzId: 403, regionId: 409 }, success: function(message) { if (message != 'Success') alert(message); }, failure: function(message) { alert(message); } }); [HttpGet] public JsonResult AssignFmzToRegion(long fmzId, long regionId) { try { FacilityManagementZoneService.AssignFmzToRegion(fmzId, regionId); } catch (Exception e) { return this.Json(e.Message, JsonRequestBehavior.AllowGet); } return this.Json("Success", JsonRequestBehavior.AllowGet); } Thanks.

  • Socket : can an asynchronous Receive returns without reading all the bytes I asked for?

    - by NorthWind
    Hi; I was reading an article on Vadym Stetsiak's blog about how to transfer variable length messages with async sockets (url: http://vadmyst.blogspot.com/2008/03/part-2-how-to-transfer-fixed-sized-data.html). He says : What to expect when multiple messages arrive at the server? While dealing with multiple messages one has to remember that receive operation can return arbitrary number of bytes being read from the net. Typically that size is from 0 to specified buffer length in the Receive or BeginReceive methods. So, even if I tell BeginReceive to read 100 bytes, it may read less than that and returns??? I am developing a network-enabled software (TCP/IP), and I always receive the same exact number of bytes I asked for. I don't even understand the logic : why would Receive completes asynchronously if it didn't get every byte I asked for ... just keep waiting. Maybe it has something to do with IP vs TCP? Thank you for your help.

  • VS 11 with std::future - Is this a bug?

    - by cooky451
    I recently installed the Visual Studio 11 Developer Preview. While playing with threads and futures, I came around this setup: #include <future> #include <iostream> int foo(unsigned a, unsigned b) { return 5; } int main() { std::future<int> f = std::async(foo, 5, 7); std::cout << f.get(); } So, very simple. But since there are two arguments for "foo", VS 11 doesn't want to compile it. (However, g++ does: http://ideone.com/ANrPj) (The runtime error is no problem: std::future exception on gcc experimental implementation of C++0x) (VS 11 errormessage: http://pastebin.com/F9Xunh2s) I'm a little confused right now, since this error seems extremely obvious to me, even if it is a developer preview. So my questions are: Is this code correct according to the C++11 standard? Is this bug already known/reported?

  • WCF: What is the practical difference between transport and message reliability?

    - by mrlane
    Hello I am looking at differences between using WPF in .NET or using Silverlight 4 for the GUI front end of an app that connects to WCF services. I have read that net.tcp binding in Silverlight 4 only supports transport level reliability. With a WPF desktop app we can use message level reliability. What is the actual difference? If transport level reliability ensures that all TCP packets get through, doesnt that also mean that all WCF SOAP messages will also get through? I am also concerned that Silverlight only supports async message but thats a different issue. Thanks

  • Tornado Web & Persistent Connections

    - by Engrost
    How can I write Http server in TornadoWeb that will support persistent Connections. I mean will be able to receive many requests and answer to them without closing connection. How does it actually work in async? I just want to know how to write handler to handle persistent connection. How actually would it work? I have handler like that: class MainHandler(RequestHandler): count = 0 @asynchronous def post(self): #get header content type content_type = self.request.headers.get('Content-Type') if not content_type in ACCEPTED_CONTENT: raise HTTPError(403, 'Incorrect content type') text = self.request.body self.count += 1 command = CommandObject(text, self.count, callback = self.async_callback(self.on_response)) command.execute() def on_response(self, response): if response.error: raise HTTPError(500) body = response.body self.write(body) self.flush() execute calls callback when finishes. is my asumption right that with things that way post will be called many times and for one connection count will increase with each httprequest from client? but for each connection I will have separate count value?

  • jQuery Ajax post with dynamic url

    - by morpheous
    I want to send an AJAX POST, but I want the url that the data is sent to, to be derived from the id of the element that was clicked. This is what I have so far: I have written a javascript function (get_my_url) that returns a url, depending on the element id that was passed to the function. The problem is, it is not clear how to bind the function (get_my_url) to the url param of the .ajax() method. jQuery('.elem1').click(function(){ jQuery.ajax({ async: false, type: 'POST', url: get_my_url(jQuery(this).attr('id')), data: 'id1=1', dataType: 'json', success: function(data){ msg = data.msg }, error: function(xrq, status, et){msg='Oops. An error occured!'} }); Does anyone know how to pass a function to the url param?

  • Rotate a feature Image in Open Layers

    - by Ozaki
    I have an open layers map. It adds and removes my "imageFeature" every 10secs or so. I have a JSON feed that gives me the rotation that I need, I have a request to get that rotation and set it as a variable of rotationv. Everything works but the fact when the image is recreated it does not update the rotation. My code is as follows: JSON request: var rotationv = (function () { rotationv = null; $.ajax({ 'async': false, 'global': true, 'url': urldefault, 'dataType': "json", 'success': function (data) { rotationv = data.rotation; } }); return rotationv })(); Creating image feature: imageFeature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(mylon, mylat), { rotation: rotationv } ); The image is set in the styling elsewhere. Why does this not rotate my image?

  • What are the internal limits to WCF

    - by ligos
    WCF has lots of limits imposed on it to protect against DoS attacks and other developer brainlessness. What are these limits? And how can they be overriden? Specifically, if I was to try to send a large number of messages in a short period of time to a variety of different clients, what are the internal WCF limits they may cause messages to be sent slowly. PS: this question is a much shorter version of my previous question that did not get much attention. EDIT I have answered the original question. The issue being my async calls were being turned into synchronous ones.
