  • Header Setup in SOAP with ASP.NET 3.5 WCF

    - by Adam
    I'm pretty new to SOAP so go easy on me. I'm trying to setup a SOAP service that accepts the following header format: <soap:Header> <wsse:Security> <wsse:UsernameToken wsu:Id='SecurityToken-securityToken'> <wsse:Username>Username</wsse:Username> <wsse:Password>Password</wsse:Password> <wsu:Created>Timestamp</wsu:Created> </wsse:UsernameToken> </wsse:Security> </soap:Header> The application I'm incorporating this service into is an ASP.NET 3.5 web application and I've already setup a SOAP endpoint using WCF. I've setup a basic service to make sure the WCF works and it works fine (disregarding the header). I heard that the above format follows WS-Security so I added WSHttpBinding in the web.config: <service name="Nexternal.Service.XMLTools.VNService" behaviorConfiguration="VNServiceBehavior"> <!--The first endpoint would be picked up from the confirg this shows how the config can be overriden with the service host--> <endpoint address="" binding="wsHttpBinding" contract="Nexternal.Service.XMLTools.IVNService"/> </service> I downloaded a test harness (soapUI) and pasted in a test message with the above header and it came back with a 400 Bad Request error. ...for what it's worth, I'm running Visual Studio 2008 using IIS7. I feel like I'm going in circles so any help would be awesome. Thanks in advance.

  • Best Practices for Internationalizing a Flex Appliaction?

    - by rgould
    I am looking into internationalizing a Flex application I am working on and I am curious if there are any best practices or recommendations for doing so. Googling for such information results in a handful of small articles and blog posts, each about doing it differently, and the advantages and disadvantages are not exactly clear. Edited to narrow scope: Need to support only two languages (en_CA and fr_CA) Need to be able to switch at runtime

  • Saving JQuery Draggable Sitemap Values Correctly

    - by mdolon
    I am trying to implement Boagworld's Sitemap tutorial, however I am running into difficulty trying to correctly save the child/parent relationships. The HTML is as follows, however populated with other items as well: <input type="hidden" name="sitemap-order" id="sitemap-order" value="" /> <ul id=”sitemap”> <li id="1"> <dl> <dt><a href=”#”>expand/collapse</a> <a href=”#”>Page Title</a></dt> <dd>Text Page</dd> <dd>Published</dd> <dd><a href=”#”>delete</a></dd> </dl> <ul><!–child pages–></ul> </li> </ul> And here is the JQuery code: $('#sitemap li').prepend('<div class="dropzone"></div>'); $('#sitemap li').draggable({ handle: ' > dl', opacity: .8, addClasses: false, helper: 'clone', zIndex: 100 }); var order = ""; $('#sitemap dl, #sitemap .dropzone').droppable({ accept: '#sitemap li', tolerance: 'pointer', drop: function(e, ui) { var li = $(this).parent(); var child = !$(this).hasClass('dropzone'); //If this is our first child, we'll need a ul to drop into. if (child && li.children('ul').length == 0) { li.append('<ul/>'); } //ui.draggable is our reference to the item that's been dragged. if (child) { li.children('ul').append(ui.draggable); }else { li.before(ui.draggable); } //reset our background colours. li.find('dl,.dropzone').css({ backgroundColor: '', backgroundColor: '' }); li.find('.dropzone').css({ height: '8px', margin: '0' }); // THE PROBLEM: var parentid = $(this).parent().attr('id'); menuorder += ui.draggable.attr('id')+'=>'+parentid+','; $("#sitemap-order").val(order); }, over: function() { $(this).filter('dl').css({ backgroundColor: '#ccc' }); $(this).filter('.dropzone').css({ backgroundColor: '#aaa', height: '30px', margin: '5px 0'}); }, out: function() { $(this).filter('dl').css({ backgroundColor: '' }); $(this).filter('.dropzone').css({ backgroundColor: '', height: '8px', margin: '0' }); } }); When moving items into the top-level (without parents), the parentid value I get is of the first list item (the parent container), so I can never remove the parent value and have a top-level item. Is there a no-brainer answer that I'm just not seeing right now? Any help is appreciated.

  • JQuery: Get length of JSON reply?

    - by Rosarch
    In a JQuery getJSON call, how can I tell the length of the JSON that's returned? function refreshRoomList() { $.getJSON('API/list_rooms', function (rooms) { if (rooms.length > 0) { $("#existing-room-list").empty(); $("#join-existing-room").text("Join existing room:"); // this shouldn't be here $.each(rooms, function (index, roomName) { var newChild = sprintf('<li><a href="room?key=%s">%s</a></li>', index, roomName); $("#existing-room-list").append(newChild); }); } else { $("#join-existing-room").text("No rooms found."); } }); } For some reason this doesn't work, but if I replace rooms.length > 0 with true, the full list of rooms is printed out.

  • Chaning coding style due to Android GC performance, how far is too far?

    - by Benju
    I keep hearing that Android applications should try to limit the number of objects created in order to reduce the workload on the garbage collector. It makes sense that you may not want to created massive numbers of objects to track on a limited memory footprint, for example on a traditional server application created 100,000 objects within a few seconds would not be unheard of. The problem is how far should I take this? I've seen tons of examples of Android applications relying on static state in order supposedly "speed things up". Does increasing the number of instances that need to be garbage collected from dozens to hundreds really make that big of a difference? I can imagine changing my coding style to now created hundreds of thousands of objects like you might have on a full-blown Java-EE server but relying on a bunch of static state to (supposedly) reduce the number of objects to be garbage collected seems odd. How much is it really necessary to change your coding style in order to create performance Android apps?

  • Pull dynamic string out of embedded RESX

    - by AC
    I have a RESX resource file that I can retrieve the values out of using the strongly typed properties and assign to values in my Silverlight 3 app. However at runtime I need to generate the lookup key based on some values to avoid a ton of if/switch statements. I'm trying to use the ResourceManager, but it doesn't like .resx files. Searched far and wide... is this just not possible in SL3? Does anyone have another suggestion?

  • How to return string name of calling method?

    - by keruilin
    Right now my code works as such: def method_a self.method_b ==> 'method_b' end def method_b puts self.name_of_calling_method end def name_of_calling_method if /`(.*)'/.match(caller.first) return $1 else return nil end end Instead of method_b printing 'method_b', how can I print the name of the calling method - 'method_a'?

  • Google Maps as background

    - by Puru puru rin..
    Hi, Is there a sexy way to get a web page with Google Maps (in fullscreen), and just a small div#header on the top and a small div#container on the middle? I had make some research and I had found this example: http://koti.mbnet.fi/ojalesa/exam/index.html ... but this is not exactly what I would like to do. If you have a thin code example of a nice website example, this would help me a lot. Many Thanks.

  • What is the possible benefit (if any) of allowing recursive contructors?

    - by Penang
    In Java, constructors cannot be recursive. Compile time error: "recursive constructor invocation". Let's assume that we did not have this restriction. Things to keep in mind: The return type of a constructor is void. Since it is a void method you can't harness the complete power of recursion. A constructor can invoke itself (or any other constructor) using this(). But a "call to this must be first statement in constructor" We could use non local data between consecutive calls to still have some possible gain from recursive constructors. Would there be any benefit from allowing recursive constructors?

  • closure not working

    - by dorelal
    var Dog = function() { var _instance = 'hello world'; return function() { console.log(this._instance); } } (); //note that it is self invoking function var l = new Dog(); //#> undefined In the above case I was expecting output of 'hello world'. Why this._instance is not accessing the the varible which should be accessible by virtue of closure. I tested this in FF and am getting undefined.

  • Finding duplicate values in a SQL table

    - by Alex
    It's easy to find duplicates with one field SELECT name, COUNT(email) FROM users GROUP BY email HAVING ( COUNT(email) > 1 ) So if we have a table ID NAME EMAIL 1 John [email protected] 2 Sam [email protected] 3 Tom [email protected] 4 Bob [email protected] 5 Tom [email protected] This query will give us John, Sam, Tom, Tom because they all have the same e-mails. But what I want, is to get duplicates with the same e-mails and names. I want to get Tom, Tom. I made a mistake, and allowed to insert duplicate name and e-mail values. Now I need to remove/change the duplicates. But I need to find them first.

  • Problems with classes (super new)

    - by user260036
    Hi, I've problems to figure it out what's happening in the following exercise, I'm learning Smalltalk, so I'm newbie. Class Anew ^super new initialize. Ainitialize a:=0. Class Bnew: aParameter |instance| instance := super new. instance b: instance a + aParameter. ^instance Binitialize b:=0. The problem says what happen when the following code is executed: B new:10. But I can't not figure it out why instance variable does not belong to A class. Thanks

  • Variable scoping and the jQuery.getJSON() method

    - by jerome
    The jQuery.getJSON() method seems to ignore the normal rules of scoping within JavaScript. Given code such as this... someObject = { someMethod: function(){ var foo; $.getJSON('http://www.somewhere.com/some_resource', function(data){ foo = data.bar; }); alert(foo); // undefined } } someObject.someMethod(); Is there a best practice for accessing the value of the variable outside of the getJSON scope?

  • Bounding Boxes for Circle and Arcs in 3D

    - by David Rutten
    Given curves of type Circle and Circular-Arc in 3D space, what is a good way to compute accurate bounding boxes (world axis aligned)? Edit: found solution for circles, still need help with Arcs. C# snippet for solving BoundingBoxes for Circles: public static BoundingBox CircleBBox(Circle circle) { Point3d O = circle.Center; Vector3d N = circle.Normal; double ax = Angle(N, new Vector3d(1,0,0)); double ay = Angle(N, new Vector3d(0,1,0)); double az = Angle(N, new Vector3d(0,0,1)); Vector3d R = new Vector3d(Math.Sin(ax), Math.Sin(ay), Math.Sin(az)); R *= circle.Radius; return new BoundingBox(O - R, O + R); } private static double Angle(Vector3d A, Vector3d B) { double dP = A * B; if (dP <= -1.0) { return Math.PI; } if (dP >= +1.0) { return 0.0; } return Math.Acos(dP); }

  • Wnat is the preferred method of building extremely lightweight business object / DAL now that I have

    - by Seth Spearman
    Hello, I have completed a simple database for a project. Only 6tables. Of the 6, one is a "lookup" table. There is one "master" table that is the driver for the system. It is referenced as a foreign key by the other four tables. Give that this step is completed. What is the FASTEST, EASIEST way to create POCOs/BizObjects that can load load the data and the child data. Here are my CAVEATS. *I don't want to spend more than 30-60 minutes learning how? *There is very little biz logic needed in the POCOs. They will pretty much load data. Don't even really need to write back data. *I already know CSLA (up to version 3) but I feel that is overkill for this little project. *Nevertheless, I would love it if it ROOT objects could have collection classes that contain the CHILD objects as in CSLA...but again, without using CSLA. *Please give the answer for .NET 35 but also if I was restricted to only use .NET 20. *Ideally I could just point a tool at the database and the POCOs would be genn'ed. *FREE Just curious what you guys use for this kind of scenario. I understand that this question is subjective but I want to hear a variety of answers. Seth

  • Streaming a non-PCM WAV file to a SilverLight application

    - by Satumba
    Hi, I would like to allow users to play recorded WAV files that stored on a server back to a Silverlight application as a client to play them. I saw that there is a way to play a WAV file on Silverlight (here), but when i tried to impliment it, i got an error playing the file because it is not in PCM format but encoded. The files that i'm trying to play are encoded with a special encoder, so i thought that the only way is to decode the WAV file on the server and stream it back to the client. The limitation is that the decode process should occur in real time because it is not reasonable to convert all the WAV files that exists. Is it possible to do it? Which streamer can i use? (Windows Media Service can help here?) Does somebody has any experience with such a scenario? Appreciate your help.
