  • NOT IN statement for Visual Studio's Query Builder for TableAdapter

    - by Fabiano
    Hi I want to realize a query with the Visual Studio 2008 build in Query Builder for a TableAdapter similar like following (MSSQL 2008): select * from [MyDB].[dbo].[MyView] where UNIQUE_ID NOT IN ('MyUniqueID1','MyUniqueID2') How do I have to set the Filter in my query in order to call it with the myTableAdapter.GetDataExceptUniqueIds(...) function? I tried to set the filter to NOT IN (@ids) and called it with string[] uniqueIds = ...; myTableAdapter.GetDataExceptUniqueIds(String.Join("','", uniqueIds)); and with StringBuilder sb = new StringBuilder("'"); sb.Append(String.Join("','", uniqueIds)); sb.Append("'"); return myTableAdapter.GetDataExceptUniqueIds(sb.ToString()); but both failed

  • When to use AsyncOperation and AsyncOperationManager

    - by Sir Psycho
    Hi, I've spent many many hours tonight reading up on implementing the event-based asynchronous pattern Unfortunately, I haven't been able to find any articles at all on witting a class that only supports one Async invocation. Every example I've seen assumes that a method call will be called more than once and thus, should have a userState object passed into the MethodNameAsync You'll see that MS makes mention of this in the third bullet point on this article http://msdn.microsoft.com/en-us/library/ms228974(VS.80).aspx under the "Simultaneously Executing Operations" heading. But I'm confused. Should I be using AsyncOperation and AsyncOperationManager classes to have asynchronous functionality where a method can only be called by one thread at a time? A link would also be nice :) Thanks

  • How does Facebook chat avoid continuous polling of the server?

    - by Chad Johnson
    I am trying to understand how Facebook's chat feature receives messages without continuously poling the server. Firebug shows me a single GET XmlHttpRequest continuously sitting there, waiting for a response from the server. After 5 minutes, this never timed out. How are they preventing timeout? An AJAX request can just sit there like that indefinitely, waiting for a response? Can I do this with JSONRequest? I see this at json.org: JSONRequest is designed to support duplex connections. This permits applications in which the server can asynchronously initiate transmissions. This is done by using two simultaneous requests: one to send and the other to receive. By using the timeout parameter, a POST request can be left pending until the server determines that it has timely data to send. Or is there another way to let an AJAX call just sit there, waiting, besides using JSONRequest?

  • Java Logger with Servlets

    - by Sunny
    Hi Guys, I am using a wrapper class A which initializes the java.util.logger static class A { public static Logger logger; public static void init(){ logger = Logger.getLogger("test"); } Now, everywhere in my program I call A.init() and then logger.log("Message+uniqid"). But recently I moved to HTTP servlets and I am having problems. Basically, If a app is already running and the logger is logging... and someone else runs the app again, the logger from the previous instance stops and starts logging for the second one. Can anyone have a solution to how I should go about fixing this static variable issue? I can pass the logger into all constructor classes but thats really tedious. Any better solution would be appreciated..

  • Firefox Extension needs to get cookie from PHP redirected external page.

    - by Tyler
    I am writing a firefox extension that interacts with a JSON server interface. I receive a url to the server which then redirects to the client site that provides the cookie. I need to be able to set this cookie in the users browser without physically loading it in the browser. Is this possible through an AJAX call? I tried using a hidden iframe, however firefox does not seem to like a php redirect in the iframe. My current solution is to load the site in a second tab that never gains focus and then auto close it when the cookie is set. This is very messy and would prefer something more streamlines. Any thoughts?

  • C# 4: conflicting overloaded methods with optional parameters

    - by Thomas
    I have two overloaded methods, one with an optional parameter. void foo(string a) { } void foo(string a, int b = 0) { } now I call: foo("abc"); interestingly the first overload is called. why not the second overload with optional value set to zero? To be honest, I would have expect the compiler to bring an error, at least a warning to avoid unintentional execution of the wrong method. What's the reason for this behaviour? Why did the C# team define it that way? Thanks for your opinions!

  • how can i add a Customcontrol to another Customcontrol

    - by scatman
    i want to create a CustomControl: TextList that extends a listBox. TextList : ListBox on CreateChildControls of the TextList i tried to put the followig code in order to create a textbox for every listBox: protected override void CreateChildControls() { TextBox t = new TextBox(); t.ID ="1"; //just an example this.Controls.Add(t); base.CreateChildControls(); } the textbox is not displayed when i call TextList in aspx. i don't think that this is the right way of doing it. so is there a possible workaround to add a control to another control?

  • Setting the content-type of requests performed by jQuery jqGrid

    - by Nigel
    I am using the latest version of jqGrid: 3.6.4 This seems like a simple problem (or at least it did before I spent a few hours on it): When the grid sends a request to the server (to a controller action), its content-type is always: application/x-www-form-urlencoded; charset=UTF-8 and I would like it to be: application/json; charset=utf-8 but I can find no way of setting the content-type (there is no contentType option as you would find on a $.ajax call for example). So just to clarify, I am not asking how to set the content-type on a jQuery server request, but specifically using jqGrid, which does not provide an obvious option for doing this. Thanks, Nigel.

  • Serializing an object into the body of a WCF request using webHttpBinding

    - by Bert
    I have a WCF service exposed with a webHttpBinding endpoint. [OperationContract(IsOneWay = true)] [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "/?action=DoSomething&v1={value1}&v2={value2}")] void DoSomething(string value1, string value2, MySimpleObject value3); In theory, if I call this, the first two parameters (value1 & value 2) are taken from the Uri and the final one (value3) should be deserialized from the body of the request. Assuming I am using Json as the RequestFormat, what is the best way of serialising an instance of MySimpleObject into the body of the request before I send it ? This, for instance, does not seem to work : HttpWebRequest sendRequest = (HttpWebRequest)WebRequest.Create(url); sendRequest.ContentType = "application/json"; sendRequest.Method = "POST"; using (var sendRequestStream = sendRequest.GetRequestStream()) { DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(MySimpleObject)); jsonSerializer.WriteObject(sendRequestStream, obj); sendRequestStream.Close(); } sendRequest.GetResponse().Close();

  • [PHP] Difference between normal and magic setters and getters

    - by Saif Bechan
    I am using a magic getter/setter class for my session variables, but I don't see any difference between normal setters and getters. The code: class session { public function __set($name, $value) { $_SESSION[$name] = $value; } public function __unset($name) { unset($_SESSION[$name]); } public function __get($name) { if(isset($_SESSION[$name])) { return $_SESSION[$name]; } } } Now the first thing I noticed is that I have to call $session->_unset('var_name') to remove the variable, nothing 'magical' about that. Secondly when I try to use $session->some_var this does not work. I can only get the session variable using $_SESSION['some_var']. I have looked at the PHP manual but the functions look the same as mine. Am I doing something wrong, or is there not really anything magic about these functions.

My client is a .net application targetting .Net 1.1, using visual studio I have created the proxy( Added a new web reference pointing to my WCF service) I am able to call methods in the WCF service but not able to pass the data in message header.

Any idea how to solve this prob?

  • TypeInitializationException When Getting an NHibernate Session

    - by Paul Johnson
    I’ve run into what appears to be an NHibernate config problem. Basically, I ran up a simple proof of concept persistence integration test using NUnit, the test simply querys an Oracle database and successfully returns the last record received by the underlying table. However, when the assemblies are taken out of the NUnit test environment and deployed as they would be for an actual application build, my call for an NHibernate session results in a ‘TypeInitializationException’ whilst executing the code line: sessionFactory = New Configuration().Configure().BuildSessionFactory() The application is a vb.net console app running against an Oracle 9.2 database, using a ‘coding framework’ published on the web by Bill McCafferty entitled 'NHibernate Best Practices with ASP.NET' (pre S#harp Architecture). I am running version 2.1.2.4000 of NHibernate. Any assistance much appreciated. Kind Regards Paul J.

  • JavaScript-like Object in Python standard library?

    - by David Wolever
    Quite often, I find myself wanting a simple, "dump" object in Python which behaves like a JavaScript object (ie, its members can be accessed either with .member or with ['member']). Usually I'll just stick this at the top of the .py: class DumbObject(dict): def __getattr__(self, attr): return self[attr] def __stattr__(self, attr, value): self[attr] = value But that's kind of lame, and there is at least one bug with that implementation (although I can't remember what it is). So, is there something similar in the standard library? And, for the record, simply instanciating object doesn't work: obj = object() obj.airspeed = 42 Traceback (most recent call last): File "", line 1, in AttributeError: 'object' object has no attribute 'airspeed' Thanks, David

  • Is it possible to load ListPreference items from an adapter?

    - by Brad Hein
    I'm setting out to create a settings activity for my app. I've defined a PreferenceActivity with a nice layout including a ListPreference object for the user to select a bluetooth device. I'm having trouble dynamically populating the list. I would like to populate ListPreference with values from an array adapter (which I'll create and populate with relevant bluetooth device names). If this were a spinner View, I could just call setAdapter(). However with the ListPreference object I can't figure out how to attach an adapter (findviewByID won't cast from View To ListPreference, so I can't even get a handle to the object). I would like to attach an adapter and then populate the adapter with values, which in turn would populate the ListPreference with values.

  • SQL Server Bulk Insert failing when called from .NET SqlCommand

    - by Nick Wright
    I have a stored procedure which does bulk insert on a SQL server 2005 database. When I call this stored procedure from some SQL (passing in the name of a local format file and data file) it works fine. Every time. However, when this same stored procedure gets called from C# .NET 3.5 code using SqlCommand.ExecuteNonQuery it works intermittently. When it fails a SqlException is generated stating "Cannot bulk load. Invalid column number in the format file "c:\bulkinsert\MyFile.fmt" I don't think this error message is correct. Has anyone experienced similar problems with calling bulk insert from code? Thanks.

  • Python: Why can't I use `super` on a class?

    - by cool-RR
    Why can't I use super to get a method of a class's superclass? Example: Python 3.1.3 >>> class A(object): ... def my_method(self): pass >>> class B(A): ... def my_method(self): pass >>> super(B).my_method Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> super(B).my_method AttributeError: 'super' object has no attribute 'my_method' (Of course this is a trivial case where I could just do A.my_method, but I needed this for a case of diamond-inheritance.) According to super's documentation, it seems like what I want should be possible. This is super's documentation: (Emphasis mine) super() - same as super(__class__, <first argument>) super(type) - unbound super object super(type, obj) - bound super object; requires isinstance(obj, type) super(type, type2) - bound super object; requires issubclass(type2, type) [non-relevant examples redacted]

  • How many javascript link I can have in Facebook?

    - by Murvinlai
    Is there a limit of how many js file I can include () in facebook? I include 5 files. no problem.. the 6th one not loaded. Then I have to put the code in the 6th one into the 5th file. then works. so, is it 5 files in max? BY THE WAY, I'm developing the apps now, not in production. so it is not in the stage of compressing JS / minizing it. :) so it is kinda annoying to got missing js files or files not loaded..etc so, what is the limit from FB? what is the file size limit? I know that the JSON request call back data limit is 5000.. but not sure about the js include.

  • Javascript - how to change elements content inside a page when using iframes, using dom, not jquery

    - by Erez
    Hello all, I have this iframe and as u can see it call a js function with the onload trigger. <iframe name="top" id="top" width="99%" height="20%" src="top.htm" frameborder="0" scrolling="no" onload="log_in()"></iframe> What i need to do is to effect the element inside "top.htm" (change innerHTML and stuff like that) from that function. But the problem is that the funnction does not recognize the elements of the "top.htm" page, only the ones in index.htm (the page with the iframes). p.s. i have to use DOM and i have to use iframes. Any one knows how to do that? 10x :-)

  • MonoRail - Select parent category from one dropdown, show child category dropdown

    - by Justin
    Hey, I'm new to MonoRail and am trying to figure out how to have it so that I can select a parent category in a dropdown then have it show a second dropdown with the categories that are children of the parent. If I were using what I'm used to, ASP.NET MVC, I would have a javascript function that would be called onchange of the first dropdown and would make an ajax call to a controller method (passing in the selected parent category id) that would grab all child categories of that parent category and return them in JSON. Then in the callback javascript function I would eval the JSON and populate the second dropdown with the child categories. How would I do this using MonoRail/jQuery? Here's the code I have so far: $FormHelper.Select("business.category.id", $categories, "%{value='id', text='name', firstoption='Select a Category'}") $FormHelper.Select("business.category.id", $childCategories, "%{value='id', text='name', firstoption='Select a Sub-Category'}") Then in BusinessController.cs: private void AddDataToModels() { PropertyBag["categories"] = CategoryRepository.GetParentCategories(); PropertyBag["childCategories"] = CategoryRepository.GetChildCategories(1); } Thanks for any input on how to approach this!

  • Add Event Handler To Dynamic Dropdownlist

    - by Andrea Girardi
    Hi all! I have a page that contains dynamically generated Dropdown List controls and I want thant the dynamic dropdown list perform an AutoPostback to fill some other field using the value selected. This is the code I'm using to create dynamically the control: If (Not IsPostBack) Then Dim newDDL As DropDownList = New DropDownList() AddHandler newDDL.SelectedIndexChanged, AddressOf ChangeValue newDDL.ID = "Level1" [fill the DropDownList] newDDL.Items.Insert(results.Count, New ListItem("", -1)) newDDL.Width = "300" newDDL.AutoPostBack = True newDDL.SelectedIndex = results.Count LevelDDLs.Controls.Add(newDDL) LevelDDLs.Controls.Add(New LiteralControl("<br /><br />")) End If Control is correctly filled and rendered on ASP page but, after selecting a value, the page is reloaded (AutoPostBack is called) but the control is not diplayed and the sub is not called. I put a breakpoint into the ChangeValue sub but anything happens. I read on some post that handler for the first DropDownList is not necessary but, how is it possible to tell DropDownList to call my sub after changevalue? Could you help me, please? many thanks, Andrea

  • Update configSource of XML element in web.config using Powershell by passing in Parameters

    I am trying to figure out a way to update my web.config for different environments by updating the configSource for the appSettings element in the web.config. Here are the way I know how to do it. $xml.get_DocumentElement().appSettings.configSource = $replaced_test The problem is that I want one base script where I can pass in different nodes to the script that I want to change and update but I am not sure how to do it. For example, I want to be able to call a powershell script like this changeWebConfig.ps1 nodeToChange newValueofNode I hope this was clear enough. This is the code I have now. $webConfigPath = "C:\web.config" # Get the content of the config file and cast it to XML $xml = [xml](get-content $webConfigPath) #this was the trick I had been looking for $root = $xml.get_DocumentElement()."system.serviceModel".client.configSource = $replace # Save it $xml.Save($webConfigPath)
