  • Error when using jquery webservice call to populate dropdownlist

    - by bugz
    For some reason when i tested parsing a json string to a dropdownlist it worked doing this var json = [{ "Id": "12345", "WorkUnitId": "SR0001954", "Description": "Test Service Request From Serena", "WorkUnitCategory": "ServiceRequest" }, { "Id": "12355", "WorkUnitId": "WOR001854", "Description": "Test Work Order From Serena", "WorkUnitCategory": "ServiceRequest" }, { "Id": "12365", "WorkUnitId": "DBR001274", "Description": "Test Database Related Service Request From Serena", "WorkUnitCategory": "ServiceRequest"}]; $(json).each(function() { comboboxWorkUnit.append($('<option>').val(this.Id).text(this.WorkUnitId)); }); However when i tryed taking the json from my webservice and placing it into the dropdownlist i get an error saying the dropdownlist doesnt support this metod. $.ajax({ type: "POST", url: "Services/WorkUnitService.asmx/WorkUnit", data: "{'Number' : '" + Number.text() + "','Id': '" + combobox.val() + "','workerType': '" + EmployeeType + "'}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(json) { $(json).each(function() { comboboxWorkUnit.append($('<option>').val(this.Id).text(this.WorkUnitId)); }); } }); I also tried which called the webservice method but through an error $.postJSON("Services/WorkUnitService.asmx/WorkUnitsForParAndPhase", "{'parNumber' : '" + parNumber + "','phaseId': '" + combobox.val() + "','workerType': '" + EmployeeType + "'}", function(data) { alert(data.toString()); }); And i tryed this which never called the webservice $.getJSON('Services/WorkUnitService.asmx/WorkUnitsForParAndPhase' + parNumber + '/' + combobox.val() + '/' + EmployeeType, function(myData) { alert(myData.toString()); });

  • IE sends multiple cookies with same name?

    - by akach
    I have a strange bug that occurs in IE7/XP and IE8/Vista on my website. IE sends two cookies named PHPSESSID. How to reproduce: Clear cookies in IE (not necessary if you never visited unisender.com). Visit unisender.com (exactly without www to reproduce!) and it will redirect to www.unisender.com Login with any valid username and password (I've registered username testmsdn with password testmsdn - feel free to use for testing) Run your favourite capture-the-traffic program (I prefer wireshark) Now click any menu link (e.g. "messages") Look at captured traffic - you will see that IE sends double PHPSESSID cookie (and you are logged out after click because of this). It seems like first PHPSESSID is from unisender.com and second from www.unisender.com. Captured sample: GET /en/letter_list HTTP/1.1 Accept: image/gif, image/jpeg, image/pjpeg, application/x-ms-application, application/vnd.ms-xpsdocument, application/xaml+xml, application/x-ms-xbap, application/x-shockwave-flash, / Referer: http://www.unisender.com/en/intro Accept-Language: ru User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) ; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.5.21022; .NET CLR 3.5.30729; FDM; .NET CLR 3.0.30729) Accept-Encoding: gzip, deflate Host: www.unisender.com Connection: Keep-Alive Cookie: authchallenge=3a9cfcfc9fe33822e3e21d75c8a3d3e4; PHPSESSID=14ea1cb133632951592397c86eaf037e; us_reg_ref=unknown; us_reg_url=http%3A%2F%2Funisender.com%2F; __utma=1.778517853.1271204400.1271204400.1271204400.1; __utmb=1.3.10.1271204400; __utmc=1; __utmz=1.1271204400.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); PHPSESSID=65e110aeb995a66b9dc8da5656c7a3da; last_login_name=testmsdn I've tried to use session and non-session cookies, tried to use .unisender.com instead of unisender.com for cookie - nothing helps. I suppose there should not be cookies with same name. Am I right? Is it a bug in IE? If it's a bug then is there a workaround? Or am I wrong and it's an expected behavior?

  • Are global comment systems a privacy concern?

    - by Stefano Borini
    I more and more see these global login-once comment-everywhere systems on every page. I didn't do my homework of tinkering debugging and search before asking, so my question is as follows: You login on site A and leave a comment. Now you go on site B, which uses the same global comment system. At the bottom of the page a request form with your name and data appears for you to add a comment on B page. You don't leave any comment and browse away. Does the global-comment provider get information about the fact that you visited page B, even if you don't leave any comment ? I will dig into the code as soon as I have time, but in the meanwhile I would like to ask your insights on this regard.

  • Making web server in C with native scripting support

    - by guitar-
    I'm an intermediate C developer, trying to get better. I want to make a very basic and lightweight HTTP server with its own scripting language. Could I use something like Lua for scripting? If not, what? I don't want to use CGI/FastCGI like Apache does for PHP in most cases, I want my server to natively support my scripting language.

  • How many rewrite rules should I expect to manage?

    - by Scott Ackerson
    I'm dealing with a hosting team that is fairly skiddish of managing many rewrite rules. What are your experiences with the number of rules your sites are currently managing? I can see dozens (if not more) coming up as the site grows and contracts and need to set expectations that this isn't out of the norm. Thanks

  • Parent Thread exiting before Child Threads [python]

    - by crgwbr
    I'm using Python in a webapp (CGI for testing, FastCGI for production) that needs to send an occasional email (when a user registers or something else important happens). Since communicating with an SMTP server takes a long time, I'd like to spawn a thread for the mail function so that the rest of the app can finish up the request without waiting for the email to finish sending. I tried using thread.start_new(func, (args)), but the Parent return's and exits before the sending is complete, thereby killing the sending process before it does anything useful. Is there anyway to keep the process alive long enough for the child process to finish?

  • How to make technical training session useful and successful for trainee?

    - by metal-gear-solid
    Are these suggestions good to give for a successful training session? Practice time should be always given immediate after technical training? usually after receiving any technical session about any new thing we do routine work. If we don't do practice just after training, later when we do any work related to that training then we feel we need training again. So if we are getting training today and will not use it for some period of time (15 -30 -60 days) then the training is of no use, as it is at the wrong time. I.e. We will forget many things Any other suggestions which i should give? I'm trainee not trainer. What suggestion should i give to trainer/organizer?

  • Questions about HTML5 audio

    - by Nimbuz
    <audio src="http://upload.wikimedia.org/wikipedia/commons/8/82/Riddle_song.ogg"></audio> <ul id="lyrics"> <li>line 1</li> <li>line 2</li> <li>line 3</li> <li>and so on...</li> </ul><!-- end #lyrics --> So I want to: Highlight (change color or background) of the line that is being played. Save current time to a cookie and resume on next visit. I'm not sure if either of these are possible in HTML5, but even in Flash or other technology, I'd like to know if and how it is possible. I understand #2 is asking too much, but #1 is really important. So almost similar to this: http://randallagordon.com/jaraoke/ but all the lines are visible, just the current line is highlighted. Many thanks for your help.

  • Uniquely identifying mobile devices over a network for webforms

    - by Eric
    I'm designing a system for mobile devices that can be assigned only to one job at a time. So I need to be able to know which mobile device is being used by accessing it's own unique static IP address or its device ID. I don't want to assign an ID myself for every machine that comes in which is why a static IP would work great. However, in trying to retrieve the client ip address I'm retrieving the wireless router's ip or some other ip which is not the mobile device's ip. I want to store that ip in a table and control which jobs are assigned to it. How can I accomplish this? I've tried the following but I'm getting the wireless ip: var hostEntry = Dns.GetHostEntry(Dns.GetHostName()); var ip = ( from addr in hostEntry.AddressList where addr.AddressFamily.ToString() == "InterNetwork" select addr.ToString() ).FirstOrDefault(); I'd rather not set a cookie if there exists a better alternative. TIA!

  • What to do with lookup entities selected from drop down select ? How to send them to the service lay

    - by arrages
    I am developing a spring mvc based application. I have a simple pojo form object, the problem is that many properties will be taked from drop down lists that are populated from lookup entities, so I return the entity ID to the form object. public NewCarRequestForm { private makeId; // this are selected from a drop down. private modelId; } Should I just send this lookup entity ID to the service layer? or should I validated that this ID is correct (Somebody can send any random ID through the request) before and how? Now there is a problem if I want to validated something based on some property of the lookup entity. Do I perform a database lookup of the entity just to perform the validation? thanks.

  • integrating facebook auth into my web form app

    - by user169692
    Hi, I would like to allow my users to authorise my app with their fb on registration. All of the examples i see redirect users to the fb canvas page after authorisation, but i only want this to be a step in the registration process. Essentially, i want an icon they can click that would open up a new window where they can login to fb and a simple postback to the registration page where i would detect the login and hide the login button. Any ideas on how I can achieve this using the facebook c# sdk? Thanks and Merry Christmas :)

  • CodeIgniter Production and Developpement server on the same domain. (no subdomain)

    - by Onigoetz
    Hi, I googled this many times but now I have to ask it here. I want to make a workflow for a website for Developpement/Production. My constraint is that I use Facebook Connect (Facebook Graph now) so I need to have the dev and prod on the same domain and server. (to be able to log in and test the features) I thought I will edit the CodeIgniter Index.php to redirect if I have a specific user agent (I can edit the one of my firefox) You think it's a good Idea or you have a better one ? And now comes the eternal question : how can I deploy this the easy way ? should I use Capistrano or Phing ? or simply a script with SVN ? Please help me, I'm totally new to this Deployment thing. I used to work directly in production for my little websites or on other domains. but now it's not possible anymore.

  • using AutoCompleteTextField in wicket without String as the generic type

    - by Manuel
    Hi! This question follows this: handling to onchange event of AutoCompleteTextField in wicket I'm trying to use the AutoCompleteTextField with a custom class as the generic type, and to add an AjaxFormComponentUpdatingBehavior. What I mean is I want to have a AutoCompleteTextField<SomeClass> myAutoComplete = ...; and after that add a AjaxFormComponentUpdatingBehavior: myAutoComplete.add(new AjaxFormComponentUpdatingBehavior("onchange") { @Override protected void onUpdate(AjaxRequestTarget target) { System.out.println( "Value: "+getValue() ); } }); The problem is that for some reason, adding that behavior makes the form try to set the model object with a String (even though the AutoCompleteTextField has a generic type of SomeClass), causing a ClassCastException when the onchange event fires. Is there a way to use AutoCompleteTextField without it being AutoCompleteTextField<String>? I couldn't find any example. Thanks for your time! and thanks to the user biziclop for his help in this matter.

  • How painful is a django project upload to a live (staging) site?

    - by Ignacio
    Hi, I've getting quite fast with a small django project of mine, which I'm developing locally, of course. But, as I had never worked with django before, I'm not aware of what it implies to upload it and test it on a production server. And I'm quite curious, since I'm very eager to test an early release live. I know there is this document, which I think it'll be really helpful: http://djangobook.com/en/2.0/chapter12/ But, are there any details I should take into account before, during and after the deployment? Any advice or best practices? Thanks.
