  • Calling ASP.NET web service function via GET method with jQuery

    - by the_V
    Hi, I'm trying to call web service function via GET method using jQuery, but having a problem. This is a web service code: [WebService(Namespace = "http://something.com/samples")] [ScriptService] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class TestWebService : System.Web.Services.WebService { [WebMethod] public string Test2() { string result = null; try { result = "{'result':'success', 'datetime':'" + DateTime.Now.ToString() + "'"; } catch (Exception ex) { result = "Something wrong happened"; } return result; } } That's the way I call the function: $.ajax({ type: "GET", url: "http://localhost/testwebsite/TestWebService.asmx/Test2", data: "{}", contentType: "application/json", dataType: "json", error: function (xhr, status, error) { alert(xhr.responseText); }, success: function (msg) { alert('Call was successful!'); } }); Method is called successfully, but result string gets covered by XML tags, like this: <string> {'result':'success', 'datetime':'4/26/2010 12:11:18 PM' </string> And I get an error because of this (error handler is called). Does anybody know what can be done about this?

  • Catching the return of main function before it deallocates resources

    - by EpsilonVector
    I'm trying to implement user threads in Linux kernel 2.4, and I ran into something problematic and unexpected. Background: a thread basically executes a single function and dies, except that when I call thread_create for the first time it must turn main() into a thread as well (by default it is not a thread until the first call, which is also when all the related data structures are allocated). Since a thread executes a function and dies, we don't need to "return" anywhere with it, but we do need to save the return value to be reclaimed later with thread_join, so the hack I came up with was: when I allocate the thread stack I place a return address that points to a thread_return_handler function, which deallocates the thread, makes it a zombie, and saves its return value for later. This works for "just run a function and die" threads, but is very problematic with the main thread. Since it actually is the main function, if it returns before the other threads finish the normal return mechanism kicks in, and deallocates all the shared resources, thus screwing up all the running threads. I need to keep it from doing that. Any ideas on how it can be done?

  • What are good uses for Python3's "Function Annotations"

    - by agscala
    Function Annotations: PEP-3107 I ran across a snippet of code demonstrating Python3's function annotations. The concept is simple but I can't think of why these were implemented in Python3 or any good uses for them. Perhaps SO can enlighten me? How it works: def foo(a: 'x', b: 5 + 6, c: list) -> max(2, 9): ... function body ... Everything following the colon after an argument is an 'annotation', and the information following the -> is an annotation for the function's return value. foo.func_annotations would return a dictionary: {'a': 'x', 'b': 11, 'c': list, 'return': 9} What's the significance of having this available?

  • How can I improve this SQL to avoid several problems with its results?

    - by Josh Curren
    I am having some problems with trying to search. Currently this will only return results that have at least 1 row in the maintenance_parts table. I would like it to return results even if there are 0 parts rows. My second problem is that when you search for a vehicle and it should return multiple results (multiple maintenance rows) it will only return 1 result for that vehicle. Some Background Info: The user has 2 fields to fill out. The fields are vehicle and keywords. The vehicle field is meant to allow searching based on the make, model, VIN, truck number (often is 2 - 3 digits or a letter prefix followed by 2 digits), and a few other fields that belong to the truck table. The keywords are meant to search most fields in the maintenance and maintenance_parts tables (things like the description of the work, parts name, parts number). The maintenance_parts table can contain 0, 1, or more rows for each maintenance row. The truck table contains exactly 1 row for every maintenance row. A truck can have multiple maintenance records. "SELECT M.maintenance_id, M.some_id, M.type_code, M.service_date, M.mileage, M.mg_id, M.mg_type, M.comments, M.work_done, MATCH( M.comments, M.work_done) AGAINST( '$keywords' ) + MATCH( P.part_num, P.part_desc, P.part_ref) AGAINST( '$keywords' ) + MATCH( T.truck_number, T.make, T.model, T.engine, T.vin_number, T.transmission_number, T.comments) AGAINST( '$vehicle' ) AS score FROM maintenance M, maintenance_parts P, truck T WHERE M.maintenance_id = P.maintenance_id AND M.some_id = T.truck_id AND M.type_code = 'truck' AND ( (MATCH( T.truck_number, T.make, T.model, T.engine, T.vin_number, T.transmission_number, T.comments) AGAINST( '$vehicle' ) OR T.truck_number LIKE '%$vehicle%') OR MATCH( P.part_num, P.part_desc, P.part_ref) AGAINST( '$keywords' ) OR MATCH( M.comments, M.work_done) AGAINST( '$keywords' ) ) AND M.status = 'A' GROUP BY maintenance_id ORDER BY score DESC, maintenance_id DESC LIMIT 0, $limit"

  • odd behavior setting timeouts inside a function with global references in javascript

    - by Pablo
    Here is the the function and the globals: $note_instance = Array(); $note_count = 0; function create(text){ count = $note_count++; time = 5000; $note_instance[count] = $notifications.notify("create", text); setTimeout(function(){ $note_instance[count].close() }, time); } The function simply opens a notification, a sets a timeout to close it in 5 seconds. so if i call this create("Good Note 1"); create("Good Note 2"); create("Good Note 3"); Ecah note should close 5 seconds from their creation, however always and only the last note closes, in this case "Good Note 3". Each note object has its own entry in the the $note_instance global array so the timeouts should no be overwriting themselves. What am i missing here folks? Thanks in advance

  • Is a full list returned first and then filtered when using linq to sql to filter data from a databas

    - by RJ
    This is probably a very simple question that I am working through in an MVC project. Here's an example of what I am talking about. I have an rdml file linked to a database with a table called Users that has 500,000 rows. But I only want to find the Users who were entered on 5/7/2010. So let's say I do this in my UserRepository: from u in db.GetUsers() where u.CreatedDate = "5/7/2010" select u (doing this from memory so don't kill me if my syntax is a little off, it's the concept I am looking for) Does this statement first return all 500,000 rows and then filter it or does it only bring back the filtered list?

  • Read and write .NET Objects in SQL Database without serialization.

    - by Mohit
    Hello, I have a small query. I need to create a Caching Service of my own that will write and read .NET Objects to and from the Database. Now, I have achieved that with the help of Binary Serialization. But the Problem is I need to deliberately marked my objects as [Serializable], which makes me think that what if someone will try to add an object which is not marked as [Serializable]. Thus, I need to find a way to read and write Objects to Database without Serialization. I have one thought too.. As we all know Session can store any object in it. Now, we can make sessions to be stored in the DB, outproc. What mechanism it uses to store these objects without serializing or deserializing. Any help will be highly appreciated. Thanks. M.B

  • Which button called the function?

    - by StoneBreaker
    I have two buttons which call the same function. That functions signature is - (IBAction)eraseTextField {...} I would like to figure out what button called the function. So I would like for the functions signature to be something like - (IBAction)eraseTextField: (id)sender {...}. Is there a way for the system to know to send the id of the calling object to a function that it calls? Thanks for the help.

  • jQuery Accordion /Tabs - Call different function upon load of content

    - by Scott
    I have the following markup: <body> <div id="tabs" style="float: left"> <ul> <li><a href="ajax/question_0.html" title="Question 1"><span>Question 1</span></a></li> <li><a href="ajax/question_1.html" title="Question 2"><span>Question 2</span></a></li> <li><a href="ajax/question_2.html" title="Question 3"><span>Question 3</span></a></li> <li><a href="ajax/question_3.html" title="Question 4"><span>Question 4</span></a></li> <li><a href="ajax/question_4.html" title="Question 5"><span>Question 5</span></a></li> <li><a href="ajax/question_5.html" title="Question 6"><span>Question 6</span></a></li> </ul> <div id="dynamicContent"> </div> </div> <div class="demo-description"> <p>Click tabs to see answers to Questions</p> </div> </body> I would like to utilize an accordion or the tabs plugin from the UI. Upon completion of the load event, I'd like to call a JavaScript function, but a different function for each tab -- almost like calling onDocumentReady for a page. I have the following JavaScript: $(function() { $('#tabs').tabs().bind('tabsselect', function(event, ui) { console.log("Loading: ajax/question_" + ui.index + ".html"); return true; //Ensure that the tab gets selected }); ); That's properly loading the Ajax file and all, but whenever I attempt to do something such as evaluating a statement in the JS, it seems to be ignored. Is there any way I can do this, so that once the file is loaded my function is called -- needs to be a different function for each tab.

  • Wait for function to finish before executing the rest

    - by Wurlitzer
    When the user refreshes the page, defaultView() is called, which loads some UI elements. $.address.change() should execute when defaultView() has finished, but this doesn't happen all the time. $.address.change() cannot be in the success: callback, as it's used by the application to track URL changes. defaultView(); function defaultView() { $('#tout').fadeOut('normal', function() { $.ajax({ url: "functions.php", type: "GET", data: "defaultview=true", async: false, success: function (response) { $('#tout').html(response).fadeIn('normal'); } }); }); } $.address.change(function(hash) { hash = hash.value; getPage(hash); }); I'm at a loss as to how to make $.address.change() wait for defaultView() to finish. Any help would be appreciated.

  • JQuery\Javascript - Passing a function as a variable.

    - by Josh
    I was just curious if I could pass a function as a variable. For example: I have a function $('#validate').makeFloat({x:671,y:70,limitY:700}); I would like to do something like this: $('#validate').makeFloat({x:function(){ return $("#tabs").offset().left+$("#tabs").width();},y:70,limitY:700}); This does not work, but ideally every time the variable was accessed it would compute the new value. So if the window was resized it would automatically adjust as opposed to a variable passed in being static. I realize I can implement this directly inside the function\widget, but I was wondering if there was some way to do something like the above.

  • jquery: Toggle elements based on result from a function

    - by Svish
    I have a number of table rows that I would like to toggle the visibility of. They should be visible if a data item I have set on them earlier equals a selected value in a form. This is what I have so far: $('#category-selector').change(function(event) { var category_id = $(this).val(); if(!category_id) { $('tr', '#table tbody').show(); } else { $('tr', '#table tbody').toggle(); } }); Of course this just toggles them on and off. Thing is that I thought I was able to give toggle a function that would decide if each row should be on or off, but it turns out I can only give it a boolean condition which would be an all or nothing deal kind of... So, I have this function: function() { return $(this).data('category_id') == category_id; } How can I use that to go through all the rows and toggle them on or off? Or is there a better approach to this? What should I do?

  • What is the performance of "Merge" clause in sql server 2008?

    - by ziang
    Hi, Merge can performs insert, update, or delete operations on a target table based on the results of a join with a source table. For example, you can synchronize two tables by inserting, updating, or deleting rows in one table based on differences found in the other table. Is anyone familiar with the performance to use "Merge" versus the traditional logic to check existence and decide the update or insert then? Thanks!

  • Confused about theme function calls.

    - by Nick Lowman
    I've created a content type that has a CCK text field. When I select the text field using the Drupal Themer widget it tells me the last function called was theme_text_formatter_default() , which I found in the CCK text.module It also tells me that it's parents were; content-field.tpl.php < theme_markup < theme_markup < node.tpl.php < page.tpl.php So I assumed that somewhere in the content-field.tpl.php was the function call to theme('text_formatter_default',$element) but it wasn't in there. Just print $item['view'] used to display the content. I searched all the project files for theme('text_formatter_default',$element) and it doesn't exist. I know it's being called by the theme function as I override it in my template.php and it used my overridden function, which would only happen if was using the theme_hook$. Wouldn't it? So how is it being called? It's not that I need to override it. I'm just learning how drupal works and thought I had it sussed until this. Something must be calling it. Also, the function theme_text_formatter_default exists in the theme registry and it's overridable (if that's a word) as I did so in my template.php and it displayed. It's all quite confusing. Any help would be much appreciated

  • Creating a function to grab data from an Oracle database (array by ID)

    - by Nick
    I'm trying to create a function that will simply allow me to pass an SQL statement into it, and it will generate an array based on a unique ID I pass it: function oracleGetGata($query, $id="id") { global $conn; $sql = OCI_Parse($conn, $query); OCI_Execute($sql); OCI_Fetch_All($sql, $results, null, null, OCI_FETCHSTATEMENT_BY_ROW); return $results; }   For example I'd like this query $array = oracleGetData('select * from table') to return something like: [1] => Array ( [Title] => Title 1 [Description] => Description 1 ) [2] => Array ( [Title] => Title 2 [Description] => Description 2 ) [3] => Array ( [Title] => Title 3 [Description] => Description 3 )   Rather than what it's returning at the moment: [0] => Array ( [ID] => 3 [TITLE] => Title 3 [DESCRIPTION] => Description 3 ) [1] => Array ( [ID] => 1 [TITLE] => Title 1 [DESCRIPTION] => Description 1 ) [2] => Array ( [ID] => 2 [TITLE] => Title 2 [DESCRIPTION] => Description 2 )   I'd really appreciate any help with this, as the function would save me lots of time! Thank you.

  • C++: Declare static variable in function argument list

    - by MDC
    Is there any way at all in C++ to declare a static variable while passing it to a function? I'm looking to use a macro to expand to the expression passed to the function. The expression needs to declare and initialize a static variable on that particular line (based on the filename and line number using FILE and LINE). int foo(int b) { int c = b + 2; return c; } int main() { int a = 3; a = foo(static int h = 2); //<---- see this! cout << a; return 0; } The problem I'm trying to solve is getting the filename and line number with the FILE and LINE macros provided by the preprocessor, but then creating a lookup table with integer keys leading to the FILE, LINE pairs. For example, the key 89 may map to file foo.cpp, line 20. To get this to work, I'm trying to use local static variables, so that they are initialized only once per line execution. The static variable will be initialized by calling a function that calculates the integer key and adds an entry to the lookup table if it is not there. Right now the program uses a message class to send exception information. I'm writing a macro to wrap this class into a new class: WRAPPER_MACRO(old_class_object) will expand to NewClass(old_class_object, key_value). If I add the static variable declaration as a second line right before this, it should work. The problem is that in most places in the code, the old class object is passed as an argument to a function. So the problem becomes declaring and initializing the static variable somehow with the macro, while keeping the existing function calls.
