  • multiple forms on asp.net page for submitting feedbacks

    - by user1698985
    I want to send data to server by enclosing it in a form. However, in asp.net I can't use more than one form with runat=server attribute. Then what is the use of using multiple forms on asp.net page. I can't access the data on the server? Like facebook enclose each post feedback data in a form and then submits this to server. How to do this in asp.net. I have to send data to server when some action occurs on a post but will have to store hiddenfield and read it with javascript is it not seems messy?

  • If I use a facade class with generic methods to access the JPA API, how should I provide additional processing for specific types?

    - by Shaun
    Let's say I'm making a fairly simple web application using JAVA EE specs (I've heard this is possible). In this app, I only have about 10 domain/data objects, and these are represented by JPA Entities. Architecturally, I would consider the JPA API to perform the role of a DAO. Of course, I don't want to use the EntityManager directly in my UI (JSF) and I need to manage transactions, so I delegate these tasks to the so-called service layer. More specifically, I would like to be able to handle these tasks in a single DataService class (often also called CrudService) with generic methods. See this article by Adam Bien for an example interface: http://www.adam-bien.com/roller/abien/entry/generic_crud_service_aka_dao My project differs from that article in that I can't use EJBs, so my service classes are essentially just named beans and I handle transactions manually. Regardless, what I want is a single interface for simple CRUD operations on my data objects because having a different class for each data type would lead to a lot of duplicate and/or unnecessary code. Ideally, my views would be able to use a method such as public <T> List<T> findAll(Class<T> type) { ... } to retrieve data. Using JSF, it might look something like this: <h:dataTable value="#{dataService.findAll(data.class)}" var="d"> ... </h:dataTable> Similarly, after validating forms, my controller could submit the data with a method such as: public <T> void add(T entity) { ... } Granted, you'd probably actually want to return something useful to the caller. In any case, this works well if your data can be treated as homogenous in this manner. Alas, it breaks down when you need to perform additional processing on certain objects before passing them on to JPA. For example, let's say I'm dealing with Books and Authors which have a many-to-many relationship. Each Book has a set of IDs referring to its authors, and each Author has a set of IDs referring to their books. Normally, JPA can manage this kind of relationship for you, but in some cases it can't (for example, the google app engine JPA provider doesn't support this). Thus, when I persist a new book for example, I may need to update the corresponding author entities. My question, then, is if there's an elegant way to handle this or if I should reconsider the sanity of my whole design. Here's a couple ways I see of dealing with it: The instanceof operator. I could use this to target certain classes when special processing is needed. Perhaps maintainability suffers and it isn't beautiful code, but if there's only 10 or so domain objects it can't be all that bad... could it? Make a different service for each entity type (ie, BookService and AuthorService). All services would inherit from a generic DataService base class and override methods if special processing is needed. At this point, you could probably also just call them DAOs instead. As always, I appreciate the help. Let me know if any clarifications are needed, as I left out many smaller details.

  • handle an arrray posted with $.ajax (jquery) to a webservice

    - by burktelefon
    I'm trying to post data to a webservice (asp.net 3.5), like below (two variants, one commented): var array = [3, 2, 5, 1, 7]; var jsonString = JSON.stringify(array); //var jsonString = '{ "firstName": "John", "lastName": "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ] }' $.ajax({ type: "POST", url: "WebService2.asmx/AddRoute", data: jsonString, contentType: "application/json; charset=utf-8", dataType: "json", processData: "false", error: function(msg) { alert('error' + msg.toString); } }); So I need a matching webmethod to recieve it. Something like this: [WebMethod] public string AddRoute(/* xxx */) { //handle data } Could someone please elaborate on how I can fetch the data, where I've typed "xxx"? I would have thought "int[] array" would do the trick, but it's not working. Any help would be greatly appreciated :)

  • jquery ajax calls with scope safety

    - by acidzombie24
    My gut tells me that if i am on a laggy server and the user fires two events fast enough on the success function c will be the value of the most recent event causing func1 to use the wrong value. <--- This is a guess, i haven't proved it. Its a feeling. How do i ensure that i use the right value when calling func1? I prefer not to send c to the server and i dont know if or how to serialize the data and deserialize it back. How do i make this code safe? $('.blah').click(function (event) { var c = $(this).closest('.comment'); ... $.ajax({ url: "/u", type: "POST", dataType: "json", data: { ... }, success: function (data) { func1(c. data.blah);//here

  • Do partitions allow multiple bulk loads?

    - by ck
    I have a database that contains data for many "clients". Currently, we insert tens of thousands of rows into multiple tables every so often using .Net SqlBulkCopy which causes the entire tables to be locked and inaccessible for the duration of the transaction. As most of our business processes rely upon accessing data for only one client at a time, we would like to be able to load data for one client, while updating data for another client. To make things more fun, all PKs, FKs and clustered indexes are on GUID columns (I am looking at changing this). I'm looking at adding the ClientID into all tables, then partitioning on this. Would this give me the functionality I require?

  • C++ printf std::vector

    - by Sebtm
    How I can do something like this in C++: void my_print(format_string) { vector<string> data; //Fills vector printf(format_string, data); } my_print("%1$s - %2$s - %3$s"); my_print("%3$s - %2$s); I have not explained well before. The format string is entered by the application user. In C# this works: void my_print(format_string) { List<string> data = new List<string>(); //Fills list Console.WriteLine(format_string, data.ToArray); } my_print("{0} - {1} - {2}"); my_print("{2} - {1}");

  • How do you send an array as part of an (jquery) ajax request

    - by Ankur
    I tried to send an array as part of an ajax request like this: var query = []; // in between I add some values to 'query' $.ajax({ url: "MyServlet", data: query, dataType: "json", success: function(noOfResults) { alert(noOfResults); } }); } I wanted to see what I get back in the servlet, so I used this line: System.out.println(request.getParameterMap().toString()); Which returned {} suggesting an empty map. Firebug tells me I am getting a 400 bad request error If I send a queryString like attribute=value as the 'data' then everything works fine, so it has to do with not being able to send an array as is. What do I have to do to get that data into the servlet for further processing. I don't want to pull it out and turn it into a queryString in the JS if I can avoid it. EDIT: I used the .serializeArray() (jQuery) function before sending the data. I don't get the 400 but nothing useful is being sent through.

  • How can I extract a range of lines from a text file on unix?

    - by Adam J. Forster
    I have a ~23000 line sql dump containing several databases worth of data. I need to extract a certain section of this file (i.e. the data for a single database) and place it in a new file. I know both the start and end line numbers of the data that I want. Does anyone know a unix command (or series of commands) to extract all lines from a file between say line 16224 and 16482 and then redirect them into a new file?

  • jquery, attaching objects (instead of string attribute) to an element

    - by binaryLV
    Hi! I'm trying to build DOM with jQuery and fill it with data that is received with AJAX (data type = json). I'd like to also store this data as an object, attached to a specific DOM element. Does jQuery provide any method for this? The reason I want to do it is because only part of data is initially displayed; other data might be needed later, depending on user actions. I tried using attr(), but it stores a string "[object Object]" instead of an actual object: var div = $('<div/>'); div.attr('foo', {bar: 'foobar'}); alert(div.attr('foo')); // gives "[object Object]" alert(typeof div.attr('foo')); // gives "string" alert(div.attr('foo').bar); // gives "undefined" Another way to do this would be by "bypassing" jQuery (div[0].foo = {bar: 'foobar'};), though this seems to be a "dirty workaround", if jQuery happens to already support attaching objects. Any ideas? Thanks in advance!

  • Problem with $.get while submitting form

    - by bradenkeith
    I'm trying to verify that an Account Name is not already in use once a user fills out a form. The code looks like: $("#add_account").submit( function () { $.get( "'.url::site("ajax/check_account_name").'", {account_name: "t"}, function(data){ alert( data ); }); }); I get a $.get response if the statement sits like this: $(document).ready( function () { $.get( "'.url::site("ajax/check_account_name").'", {account_name: "t"}, function(data){ alert( data ); }); }); Which leads me to believe that my $.get statement is correct. Is there some jQuery rule I'm not familiar with that would cause this to fail in on submit scenario? In code block 1, I get values returned like they should. Block 2 gives me a blank response. Any ideas? Thanks for your time, I know you have better things to be doing.

  • DataTable from TextFile?

    - by Craig
    I have taken over an application written by another developer, which reads data from a database, and exports it. The developer used DataTables and DataAdaptors. So, _dataAdapter = new SqlDataAdapter("Select * From C....", myConnection); and then ExtractedData = new DataTable("CreditCards"); _dataAdapter.Fill(ExtractedData); ExtractedData is then passed around to do different functions. I have now been told that I need to, in addition to this, get the same format of data from some comma separated text files. The application does the same processing - it's just getting the data from two sources. So, I am wondering if I can get the data read into a DataTable, as above, and then ADD more records from a CSV file. Is this possible?
