  • Passing jQuery object and WebMethod return value to an OnSuccess function

    - by iboeno
    I am calling a WebMethod from this code: if($(this).attr("checked")) { .. MyWebMethod(variable1, variable2, onSuccessFunction); } The MyWebMethod returns an integer, and I want to set $(this).attr("id") of the jQuery object above to the returned integer. Basically, I'm trying to do the equivalent of an MVC Ajax.ActionLink...AjaxOptions {UpdateTargetID =...} However, I can't figure out how to get both a reference to $(this) as well as the returned value. For example, if I do: MyWebMethod(variable1, variable2, onSuccessFunction($(this))); I can succesfully manipulate the jQuery object, but obviously it doesn't have the return value from the MyWebMethod. Alternatively, the first code block with a method signature of onSuccessFunction(returnValue) has the correct return value from MyWebMethod, but no concept of the jQuery object I'm looking for. Am I going about this all wrong?

  • operator not defined for System.Data.SqlClient.SqlConnection and System.Data.SqlClient.SqlConnection

    - by Beta033
    i hope i'm just doing something wrong here. Ideally i'm trying to open the connection, open a transaction execute a ton of prebuilt sqlstatements (with parameters) against this connection then close the connection. ideally all in the same batch. It's easy enough to wrap this all in a for loop, however i'd like to use the forEach function of the list generic to set the connection as it'll probably be faster than my implementation of calling List.Item(i) in the loop but i get some strange errors. Dim sqlStatements As List(Of SqlCommand) = New List(Of SqlCommand) Dim conn As SqlClient.SqlConnection = New SqlConnection("...") sqlStatements.Item(0).Connection = conn 'Works sqlStatements.ForEach(Function(ByRef cmd As SqlCommand) cmd.Connection = conn) 'ERROR: Operator '=' is not defined for types 'System.Data.SqlClient.SqlConnection' 'and 'System.Data.SqlClient.SqlConnection What does this error really mean?

    - by vinay123
    In my code I am using JSF - Front end , EJB-Middile Tier and JPA connect to DB.Calling the EJB using the Webservices.Using MySQL as DAtabase. I have created the Voter table in which I need to insert the record. I ma passing the values from the JSF to EJB, it is working.I have created JPA controller class (which automatcally generates the persistence code based on the data base classes) Ex: getting the entity manager etc., em = getEntityManager(); em.getTransaction().begin(); em.persist(voter); em.getTransaction().commit(); I have created the named query also: @NamedQuery(name = "Voter.insertRecord", query = "INSERT INTO Voter v values v.voterID = :voterID,v.password = :password,v.partSSN = :partSSN, v.address = :address, v.zipCode = :zipCode,v.ssn = :ssn, v.vFirstName = :vFirstName,v.vLastName = :vLastName,v.dob = :dob"), But still not able to insert the record?

  • Implementing a pager for asp.net's DataList/Repeater

    - by emre
    I have a DataList showing the results, and a Repeater that is supposed to be the pager. I decided to use the page number by redirecting with a QueryString parameter, so it will also be bookmarkable ... My problem is mainly in the UI actually. If I put DIV's with their onclick calling a JS function that does window.location = url + pagenumber , then somehow I have to deal with QueryString operations via JS which is a bit messy. If I use LinkButton objects within the ItemTemplate, then the Redirecting happens only when the linkbutton is clicked while whole div has cursor: pointer , you what I mean. What would be the best approach to this? Thanks in advance. Note: I really want to spend the time and effort implementing my own server-side paging. I think its more fun than reading 3rd party manuals.

  • RenderPartial from different folder in RAZOR

    - by Dien
    I've been trying to convert my aspx pages to cshtml and having an issue with rendering partial pages from another folder. What I used to do: <% Html.RenderPartial("~/Views/Inquiry/InquiryList.ascx", Model.InquiryList.OrderBy("InquiryId", MvcContrib.Sorting.SortDirection.Descending));%> I would think that the equivalent would be: @Html.RenderPartial("~/Views/Inquiry/_InquiryList.cshtml", Model.InquiryList.OrderBy("InquiryId", MvcContrib.Sorting.SortDirection.Descending)) This is obviously not working, I am getting the following error. CS1973: 'System.Web.Mvc.HtmlHelper' has no applicable method named 'Partial' but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax. How would I achieve this with using the Razor view engine?

  • SynchronizationContext and Bookmarks in WF4

    - by DBatisse
    I am running workflows under asp.net and using SynchronizationContext to make the page "wait" for the workflow. Here is how I run the workflow instance under asp.net: var workflowApplication = new WorkflowApplication(activity); SynchronizationContext syncContext = SynchronizationContext.Current; workflowApplication.Completed = delegate { syncContext.OperationCompleted(); }; workflowApplication.SynchronizationContext = syncContext; syncContext.OperationStarted(); workflowApplication.Run(); In one of the activities I use a bookmark. Now I want the page processing to continue whenever I call CreateBookmark. I tried calling SynchronizationContext.Current.OperationCompleted() before setting the bookmark but that crushes asp.net site when the workflow resumes and completes (I think the workflow instance calls OperationCompleted again when it completes and the error raises) How can I work with bookmarks under Asp.Net, any ideas?

  • How to use the Rhino javascript engine in an applet

    - by Robber
    For my java program I'm using Rhino to execute JS scripts. Now I'm trying to convert it to an applet which works great, except that everytime it's calling evaluateString(...) the JVM throws an AccessControlException. After some (a lot) of research I found out that this is caused by Rhino's custom classloader. My problem is that after hours of googling I still can't find a way to stop Rhino from trying to load it's own classloader. I hope someone can help me...

  • ctypes and PySide

    - by Timothy Baldridge
    I'm building an app with PySide, there's some image manipulation that needs to be done and using Python code for this is way too slow. Therefore I hacked out a .dll file that will do it for me. The function definition is as follows: extern "C" { QRectF get_image_slant(QImage *img, float slantangle, float offset) { Now I can load this function in via ctypes. But I can't seem to get ctypes to accept a QImage. I tried calling it like this: ext.get_image_slant(QImage(), 0, 0) And the reply I get is: File "<stdin>", line 1, in <module> ctypes.ArgumentError: argument 1: <type 'exceptions.TypeError'>: Don't know how to convert parameter 1 I tired casting the QImage to a c_void_p and it doesn't like that either. From what I can tell QImage() in python should map exactly to a QImage * in C, but Python doesn't seem to understand that.. Is there any way to force the casting?

  • java casting a list

    - by dcp
    Let's say I had: protected void performLogic(List<Object> docs) { ... } In the code where I'm going to be calling this method, I have a List<String> list. I want to call performLogic, passing this list. But it won't work because the lists are 2 different types: public void execute() { List<String> docs = new ArrayList<String>(); performLogin(docs); // won't work } I tried casting to List<Object> also, but that won't work either. So is the only way to do this is to make a new ArrayList of Object and just add the values and then pass it? Just seems cumbersome. I wondered if there was a better way to do it. Thanks.

  • Setting an delegate for the UIDatePicker animation?

    - by james.ingham
    If I had a date picker within an action sheet and called the following line: [datePicker setDate:newDate animated:YES]; And then my app hides the action sheet the date picker is within, is there anyway to set up a animation delegate so that the user see's the animation of the date picker first and then hides the action sheet? I have done this with UIView's by calling: [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(METHOD)]; However I can not see anything like this for the date picker. Thanks in advanced - James

  • Catching an exception when trying to launch a URL service from within Safari on an iPhone

    - by Ariel
    Hey guys, I was wondering if anyone knows - if I have an iPhone app that is registered with a URL service (e.g. alocola://), which means another app can invoke it by calling its URL - is there any way to embed this URL in an HTML page, and catch the exception if the app is not installed on the user's iPhone? Or in other words / more details: I would like to write an app that conforms to some URL invocation (like alocola:// is doing), but would like this app to be launched from a web page read by mobile Safari. However, if the app is not installed on the user's iphone, I would like to be able to display a note saying "you must have the alocola app installed on your iPhone, please download it from the app store by clicking here". Is there a way (perhaps using javascript) to have Safari indicate that the URL cannot be invoked, and catch this in order to display an intelligent message? Thanks :-) Ariel

  • Find new messages added to an imap mailbox since I last checked with python libimap2?

    - by vy32
    I am trying to write a program that monitors an IMAP mailbox and automatically copies every new incoming message into an "Archive" folder. I'm using imaplib2 which implements the IDLE command. Here's my basic program: M = imaplib2.IMAP4("mail.me.com") M.login(username,password) lst = M.list() assert lst[0]=='OK' for mbx in lst[1]: print "Mailboxes:",mbx def process(m): print "m=",m res = M.recent() print res M.select('INBOX') M.examine(mailbox='INBOX',callback=process) while True: print "Calling idle..." M.idle() print "back from idle" M.close() M.logout() It prints the mailboxes properly and runs process() when the first change happens to the mailbox. But the response from recent() doesn't make sense to me, and after the first message I never get any other notifications. Anyone know how to do this?

  • accessing $_SESSION when using file_get_contents in PHP

    - by hairdresser-101
    I am basic - intermediate developer using php and am a little stumped as to what I have found. I need some help in understanding how to alleviate this issue: I have a page called send.email.php which sends an email - pretty simple stuff - I pass an order id, it creates job request and sends it out. This works fine when used in the context I developed it (Use javascript to make an AJAX call to the URL and pass the order_id as a query parameter) I am now trying to reuse the exact same page in another application however I am calling it using php file_get_contents($base_url.'admin/send.email.php?order_id='.$order_id). When I call the page this way, the $_SESSION array is empty isempty() = 1. Is this because I am initiating a new session using file_get_contents and the values I stored in the $_SESSION on login are not available to me within there? Any help? Thanks

  • Adding existing entity to navigation property of a different entity

    - by Shay Friedman
    I'm using EF4 and I'm running into a problem when I try to do something that looks quite trivial to me. I have two entities, let's call them A and B. These entities have a many-to-many association between them with a navigation property on A that contains a list of related B entities. What I want to do is to add existing B entities to a new A entity. When I try to do that, I get an exception: AcceptChanges cannot continue because the object's key values conflict with another object in the ObjectStateManager. Make sure that the key values are unique before calling AcceptChanges. Has anyone run into such a problem?

  • Recursion Issue

  • Subsonic 3.0 Query limit with MySQL c#.net LinQ

    - by omegawkd
    Hello, a quick question which may or may not be easily answered. Currently, in order to return a limited result set of data to my calling reference using SubSonic I use a similar function as below: _DataSet = from CatSet in t2_aspnet_shopping_item_category.All() join CatProdAssignedLink in t2_aspnet_shopping_link_categoryproduct.All() on CatSet.CategoryID equals CatProdAssignedLink.CategoryID join ProdSet in t2_aspnet_shopping_item_product.All() on CatProdAssignedLink.ProductID equals ProdSet.ProductID where ProdSet.ProductID == __ProductID orderby CatProdAssignedLink.LinkID ascending select CatSet; and select the first item from the data set. Is there a way to limit the lookup initially to a certain amount of rows? I'm using MySQL as the base database.

  • Why can't I retrieve UIDeviceOrientation correctly while playing a movie in MPMoviePlayerController?

    - by Zelldweller
    Everything works fine while I'm not playing anything (I'm calling beginnotifications, etc, and using the orientation to rotate my view). But after I start playing with MPMoviePlayerController every time I try a... UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; ...orientation gets a UIDeviceOrientationUnknown. Any clue? When the movie stops everything works alright again. I need this orientation to rotate the player's window, because Im using Iphone OS 3.1 so I can't directly use the view property inside MPMovie player controller.

  • Limiting landscape views in UITabBarController containing UINavigationController

    - by Spider-Paddy
    I have a tab bar application that contains navigation views in 2 of its tabs. I would like 1 view in the 1 navigation controller to allow landscape view but because of the nav bar in tab bar limitation I now have to allow landscape views for every single view in my app to make the tilt messages get passed to my app which I don't want. I thought perhaps, on the views which shouldn't go to landscape, that there might be ways to either: prevent the view change e.g. calling setOrientation:UIDeviceOrientationPortrait whenever the device goes landscape or giving the illusion that the view doesn't change e.g. presenting a modal portrait view over the rotated view Anybody have any ideas or experience that they care to share? What is the best approach here? (I don't want to now have to design a landscape view for every view just to so that I can display a portrait & landscape view for 1 view)

  • jQuery Autocomplete: how to refresh list?

    - by cinematic
    I have a form with a variable number of autocomplete fields that use the same select list. These fields are added and removed as needed. Whenever a parameter on the page is changed, I (try to) update the list for all the fields by first calling unbind() then autocomplete() with a new parameter added to the url. $('input.foo').unbind().autocomplete(url?new_param=bar); The problem is that unbind() does not seem to be unbinding. When I type in the input field, it fires off the entire history of autocomplete events. I also tried flushCache to no avail. How do I clear out the old events? Thanks.

  • programmatically logout a "specific" user

    - by MD_Oppenheimer
    Is it possible in Asp.NET MVC to proframmatically logout a user? I am aware that you can use: FormsService.SignOut(); But this refers to the context of the webpage making the request. I'm trying to prevent a user logging in twice. So if I call: MembershipUser membershipUser = Membership.GetUser(userName); if (membershipUser.IsOnline == true) { // log this user out so we can log them in again FormsService.SignOut(); } calling: FormsService.SignOut(); has no bearing on the context of the user say, with another webbrowser who is logged in already??

  • OS X firewall popup about growlnotify keeps popping up

    - by Vitaly Kushner
    I have autotest setup with growlnotify using growl_glue (version 1.0.7): require 'growl_glue' GrowlGlue::Autotest.initialize do |config| config.notification :use_network_notifications => true end growl version is 1.2 each time autotest runs and displays the notification growl popup I also get an OS X firewall popup asking Do you want the application "growlnotify" to accept incoming network connections? I tried answering deny and allow but it still keeps popping up. the deny/allow choice is properly reflected in System Preferences - Security - Firewall - 'application access list', but it still asks every time. update I ended up using autotest-growl gem instead of the growl_glue. it fixed the problem, it was probably related to how growl_glue was calling growlnotify.

  • C# threading pattern that will let me flush

    - by Jeff Alexander
    I have a class that implements the Begin/End Invocation pattern where I initially used ThreadPool.QueueUserWorkItem() to do thread my work. I now have the side effect where someone using my class is calling the Begin (with callback) a ton of times to do a lot of processing so ThreadPool.QueueUserWorkItem is creating a ton of threads to do the processing. That in itself isn't bad but there are instances where they want to abandon the processing and start a new process but they are forced to wait for their first request to finish. Since ThreadPool.QueueUseWorkItem() doesn't allow me to cancel the threads I am trying to come up with a better way to queue up the work and maybe use an explicit FlushQueue() method in my class to allow the caller to abandon work in my queue. Anyone have any suggestion on a threading pattern that fits my needs?

  • Drawing a path with a line in OpenLayers using JavaScript

    - by Andreas Grech
    I have seen the examples presented here of how to draw a line but the examples only show how to do it with the mouse, by clicking. What I want to do is draw the line manually using JavaScript given a list of Longitude and Latitude coordinates. The reason I cannot work on the source provided in the link above is because they are only calling activate on the feature, and then let the user point and click on the map. Has anyone ever drew a path on an OpenLayers map programatically? What I want to do is exactly this: http://openspace.ordnancesurvey.co.uk/openspace/example4.html, but without using OpenSpace.

  • Some basic questions about Django, Pyjamas and Clean URLs

    - by Acidburn2k
    I am farily new to the topic, but I am trying to combine both Django and Pyjamas. What would be the smart way to combine the two? I am not asking about communication, but rather about the logical part. Should I just put all the Pyjamas generated JS in the base of the domain, say http://www.mysite.com/something and setup Django on a subdirectory, or even subdomain, so all the JSON calls will go for http://something.mysite.com/something ? As far as I understand now in such combination theres not much point to create views in Django? Is there some solution for clean urls in Pyjamas, or that should be solved on some oy,ther level? How? Is it a standard way to pass some arguments as GET parameteres in a clean url while calling a Pyjamas generated JS?
