  • Why won't VS2010 RC use my existing types when I add a service reference?

    - by Johan Driessen
    I have a huge problem getting services references in VS2010 RC to use existing assemblies. Even though I have a class library with all the data contracts (classes marked with DataContract and properties with DataMember) that is shared between the service project and the consuming project (which is a class library), when I add a service reference, the data contracts are regenerated withing the service reference instead of using the existing types. When I was using VS2010 beta 2, this worked fine, and I have existing service references using the very same data contracts. But if I add a new service reference, or even update an old one, it won't use the existing types anymore. I have made a mini-test-solution, with one service, one data contract type and one console app as a consumer (all in the same solution), and there it seems to work, but that's no great comfort to me. Is there any way to see why it can't use the existing types? Edit to clearify. It works to generate the proxy classes with svcutil.exe, and point to the data contracts dll, like this: svcutil.exe http://localhost/MyService.svc /reference:[Path To DataContracts]\DataContracts.dll /n:*,MyProject.MyServiceReference /ct:System.Collections.Generic.List`1 The question is, what possible reason could there be for Visual Studio to generate its own datacontracts instead of using the existing ones even though the "reuse" checkbox is checked and the datacontracts assembly is referenced.

  • weird problem with load () or live () !!

    - by silversky
    I load a page with load () and then I create dinamically a tag. Then I use live() to bind a click event and fires a function. At the end a call unload (). The problem is that when I load the same page again ( without refresh ) when on click the function will be fired twice. If I exit again (again with unload ()) and load the page again on click will fire 3 times and so on .... A sample of my code is: $('#tab').click(function() { $('#formWrap').load('newPage.php'); }); $('div').after('<p class="ctr" ></p>'); $('p.ctr').live('click', function(e) { if($(e.target).is('[k=lf]')) { console.log ('one'); delete ($this); } else if .... }); function delete () { $.post( 'update.php', data); } I have other $.post inside on this page and also on the above live fnc and all work well. The above one also works but like I said on the second load will fire twice and the 3 times and so on ... The weird part for me is that if replece the console with console.log ('two'); save the page and load the page without refresh it will fire on a different rows - one two - if I unload the page replace the console with console.log ('three'); and load again will fire one two and three. I try to use: $.ajax({ url: 'updateDB.php', data: data, type: 'POST', cache:false }); $.ajaxSetup ({ cache: false }); header("Cache-Control: no-cache"); none of this it's working. And I have this problem only on this fnc. What do you think, it could be the reason, it remembers it remembers the previous action and it fires again?

  • Zend Layout and Bootstrapping

    - by emeraldjava
    So i'm using the standard Zend Layout for my site. I have a number of custom controllers and views, and the content of these pages is displayed, but the details in the head element of the layout.phtml are not shown. Do i need to manually associate the Zend_Layout with each specific controller?. I expected since the layout is loaded via the bootstrap this should be available for free. My app.ini file has # layout resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts" resources.layout.layout = "layout" #resources.view[] = # Views resources.view.encoding = "UTF-8" resources.view.basePath = APPLICATION_PATH "/views/" my layout.phtml <?php echo $this->doctype() ?> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <?php echo $this->headTitle() ?> <?php echo $this->jQuery();?> </head> <!-- application/layouts/scripts/layout.phtml --> <body> <div id="content"> <?php echo $this->layout()->content ?> </div> </body>

  • matching an element's class to another element's ID, or *part* of another element's ID

    - by shecky
    hello again Such a simple concept but I'm struggling to express it ... apologies in advance for my verbosity. I have a container div with a class, e.g., ; I want to use that class to do two things: add a class (e.g., 'active') to the nav element whose ID matches the class of div#container (e.g., #nav-primary li# apples) add the same class to another element if part of this element's ID matches the class of #container (e.g., div#secondary-apples) I assume there's an .each() loop to check the primary nav's list items' IDs, and to check the div IDs of the secondary nav ... though the latter needs to have its prefix trimmed ... or should I say more simply if the secondary nav div IDs contain the class of div#container? I've tried a few variations of something like this: <script type="text/javascript"> $(document).ready(function() { $('#nav-primary li').each(function(){ var containerClass = $('#container').attr('class'); var secondaryID = $('#nav-primary li').attr('id'); // something like if ('#nav-primary li id' == (containerClass) { } // or should I first store a variable of the LI's ID and do something like this: if ( secondaryID == containerClass ) { } // and for the trickier part, how do I filter/trim the secondary nav div IDs, something like this: var secondaryNavID = $('#aux-left div[id ... something here to strip the 'secondary-' bit ... ]'); }); // end each }); // end doc.ready.func </script> The markup is, e.g.: ... ... ... ... ... ... ... Many thanks in advance for any suggestions, svs

  • How can I extend this SQL query to find the k nearest neighbors?

    - by Smigs
    I have a database full of two-dimensional data - points on a map. Each record has a field of the geometry type. What I need to be able to do is pass a point to a stored procedure which returns the k nearest points (k would also be passed to the sproc, but that's easy). I've found a query at http://blogs.msdn.com/isaac/archive/2008/10/23/nearest-neighbors.aspx which gets the single nearest neighbour, but I can't figure how to extend it to find the k nearest neighbours. This is the current query - T is the table, g is the geometry field, @x is the point to search around, Numbers is a table with integers 1 to n: DECLARE @start FLOAT = 1000; WITH NearestPoints AS ( SELECT TOP(1) WITH TIES *, T.g.STDistance(@x) AS dist FROM Numbers JOIN T WITH(INDEX(spatial_index)) ON T.g.STDistance(@x) < @start*POWER(2,Numbers.n) ORDER BY n ) SELECT TOP(1) * FROM NearestPoints ORDER BY n, dist The inner query selects the nearest non-empty region and the outer query then selects the top result from that region; the outer query can easily be changed to (e.g.) SELECT TOP(20), but if the nearest region only contains one result, you're stuck with that. I figure I probably need to recursively search for the first region containing k records, but without using a table variable (which would cause maintenance problems as you have to create the table structure and it's liable to change - there're lots of fields), I can't see how.

  • Boost causes an invalid block while overloading new/delete operators

    - by user555746
    Hi, I have a problem which appears to a be an invalid memory block that happens during a Boost call to Boost:runtime:cla::parser::~parser. When that global delete is called on that object, C++ asserts on the memory block as an invalid: dbgdel.cpp(52): /* verify block type */ _ASSERTE(_BLOCK_TYPE_IS_VALID(pHead->nBlockUse)); An investigation I did revealed that the problem happened because of a global overloading of the new/delete operators. Those overloadings are placed in a separate DLL. I discovered that the problem happens only when that DLL is compiled in RELEASE while the main application is compiled in DEBUG. So I thought that the Release/Debug build flavors might have created a problem like this in Boost/CRT when overloading new/delete operators. So I then tried to explicitly call to _malloc_dbg and _free_dbg withing the overloading functions even in release mode, but it didn't solve the invalid heap block problem. Any idea what the root cause of the problem is? is that situation solvable? I should stress that the problem began only when I started to use Boost. Before that CRT never complained about any invalid memory block. So could it be an internal Boost bug? Thanks!

  • Triple Quotes? How do I delimit a databound Javascript string parameter in ASP.NET?

    - by David HAust
    How do I delimit a Javascript databound string parameter in an anchor OnClick event? I have an anchor tag in an ASP.NET Repeater control. The OnClick event of the anchor contains a call to a Javascript function. The Javascript funciton takes a string for it's input parameter. The string parameter is populated with a databound value from the Repeater. I need the 'double quotes' for the Container.DataItem. I need the 'single quotes' for the OnClick. And I still need one more delimiter (triple quotes?) for the input string parameter of the Javascript function call. Since I can't use 'single quotes' again, how do I ensure the Javascript function knows the input parameter is a string and not an integer? Without the extra quotes around the input string parameter, the Javascript function thinks I'm passing in an integer. Cheers in advance for any knowledge you can drop. The anchor: <a id="aShowHide" onclick='ToggleDisplay(<%# DataBinder.Eval(Container.DataItem, "JobCode") %>);' >Show/Hide</a> and here is the Javascript: <script language="JavaScript" type="text/javascript">/* Shows/Hides the Jobs Div */ function ToggleDisplay(jobCode) { /* Each div has it's ID set dynamically ('d' plus the JobCode) */ var elem = document.getElementById('d' + jobCode); if (elem) { if (elem.style.display != 'block') { elem.style.display = 'block'; elem.style.visibility = 'visible'; } else { elem.style.display = 'none'; elem.style.visibility = 'hidden'; } } }</script>

  • NotFoundException in layout editor for Android?

    - by borg17of20
    I'm trying to extend a RelativeLayout object and include an embedded SurfaceView object that uses a png file in my /res/drawable folder as its background but I keep getting an error in the XML Layout editor. See the following code: public class StopMotionRelativeLayout extends RelativeLayout { private Context myContext; private SurfaceView surfaceView1; private BitmapFactory.Options myBitmapOptions; private final android.view.ViewGroup.LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT, android.view.ViewGroup.LayoutParams.FILL_PARENT); public StopMotionRelativeLayout(Context context, AttributeSet attrs) { super(context, attrs); myContext = context; this.setBackgroundColor(Color.GREEN); //init images surfaceView1 = new SurfaceView(myContext,attrs); surfaceView1.setVisibility(View.INVISIBLE); this.addView(surfaceView1, params); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); myBitmapOptions = new Options(); myBitmapOptions.outWidth = widthMeasureSpec; myBitmapOptions.outHeight = heightMeasureSpec; surfaceView1.setBackgroundDrawable(new BitmapDrawable(BitmapFactory.decodeResource(this.myContext.getResources(), R.drawable.golf1, myBitmapOptions))); } } I get the following error: NotFoundException: Could not find drawable resource matching value 0x7F020002 (resolved name: golf1) in current configuration. I have seen this type of error may times now and it always happens when I try to load something from a resource file via code and not XML. Curiously, this error does not stop me from compiling the app, and the app runs without error in the emulator. I'd like to get back the use of my layout editor though... Please help. UPDATE: Here is the layout XML <?xml version="1.0" encoding="utf-8"?> <com.games.test.StopMotionRelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> </com.games.test.StopMotionRelativeLayout>

  • Spring bean's DESTROY-METHOD attribute and web-application "prototype"d bean

    - by EugeneP
    Can get work the attribute "destroy-method". First, even if I type non-existing method name into "destroy-method" attribute, Spring initialization completes fine (already strange!). Next, when a bean has a "prototype" scope, then I suppose it must be destroyed before the application is closed. That not happens, it is simply never called in my case. Though, after extracting this bean I can call this method explicitly and it does its job. Could you explain why this method is never called in my Spring 2.5 case? p.s. The method exists, it is public and has no arguments. It seems to be a more difficult task then I thought. The problem is that this destroy method is called whenever the context is closed, and this is a rare case. My question is this: I have a web app. I have a "prototype"-scoped bean. What I need is when the current session is closed, this destroy method was automatically called by Spring. I can do it by hand, but is there any solution how to make Spring do this job? It destroys the bean after the session is destroyed, it might be possible for Spring to call a method on that bean before destroying it?

  • Why are custom events not working for me? (Mootools)

    - by John McCollum
    I've been learning Mootools, but I'm having problems firing custom events. I'm sure it must be something simple, but I can't see it for the life of me. I wrote a simple class to nudge some list items using Fx.Tween. It works perfectly, except that the custom events aren't being triggered, no matter what I try. <script type="text/javascript"> var Pusher = new Class({ Implements: [Events,Options], options: { elements: [] }, initialize: function(options){ this.setOptions(options); this.attachListeners(this.options.elements); }, attachListeners: function(elements){ $$(elements).each(function(el){ $(el).addEvent('mouseover', this.pushIn.bind(el)) .addEvent('mouseout', this.pushOut.bind(el)); }, this); }, pushIn: function(){ this.fireEvent('in'); this.set('tween', {duration: 'short'}); this.tween('paddingLeft', '50px'); }, pushOut: function(){ this.fireEvent('out'); this.set('tween', {duration: 'short'}); this.tween('paddingLeft', '0px'); } }); window.addEvent('domready', function(){ var p = new Pusher({ elements: $$('li') }); p.addEvent('in', function(){ alert('in'); }); p.addEvent('out', function(){ alert('out'); }); }); </script> And in the HTML: <ul id="mylist"> <li>1</li> <li>2</li> <li>3</li> <li>4</li> </ul> I've also tried the following: window.addEvent('domready', function(){ var p = new Pusher({ elements: $$('li'), onIn: function(){ alert('in'); }, onOut: function(){ alert('out'); } }); }); What am I doing wrong?

  • Netbean6.8: Cant deploy an webapp with Message Driven Bean

    - by Harry Pham
    I create an Enterprise Application CustomerApp that also generated two projects CustomerApp-ejb and CustomerApp-war. In the CustomerApp-ejb, I create a SessionBean call CustomerSessionBean.java as below. package com.customerapp.ejb; import javax.ejb.Stateless; import javax.ejb.LocalBean; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; @Stateless @LocalBean public class CustomerSessionBean { @PersistenceContext(unitName = "CustomerApp-ejbPU") private EntityManager em; public void persist(Object object) { em.persist(object); } } Now I can deploy CustomerApp-war just fine. But as soon as I create a Message Driven Bean, I cant deploy CustomerApp-war anymore. When I create NotificationBean.java (message driven bean), In the project destination option, I click add, and have NotificationQueue for the Destination Name and Destination Type is Queue. Below are the code package com.customerapp.mdb; import javax.ejb.ActivationConfigProperty; import javax.ejb.MessageDriven; import javax.jms.Message; import javax.jms.MessageListener; @MessageDriven(mappedName = "jms/NotificationQueue", activationConfig = { @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"), @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue") }) public class NotificationBean implements MessageListener { public NotificationBean() { } public void onMessage(Message message) { } } If I remove the @MessageDriven annotation, then I can deploy the project. Any idea why and how to fix it?

  • POSTing JSON data to WCF REST

    I'm trying to send data from a client application using jQuery to a REST WCF service based on the WCF REST starter kit. Here's what I have so far.

  • Straw Poll - K&R vs BSD

    - by Gordon Mackie JoanMiro
    No holy wars please - (ultimately a standardised and consistently-observed house-style on a project always wins out whatever is chosen), but I am genuinely interested in the preferences of people for K&R style formatting: public bool CompareObjects(object first, object second) { if (first == second) { return true; } else { return false; } } over BSD style: public bool CompareObjects(object first, object second) { if (first == second) { return true; } else { return false; } } K&R seems to be making a bit of a comeback recently (I'm an old programmer, so I've seen these things fluctuate); do people think K&R looks more professional, more cool, more readable, is compactness when viewing more important than extending the structure down the screen? Please use the 2 community wiki answers below to vote for K&R vs. BSD. Polls shouldn't earn rep for the first person that manages to type "BSD FTW!" My God! This question is nearly 2 years old and people are still down-voting it; ENOUGH!

  • BindingList<T> and reflection!

    - by Aren B
    Background Working in .NET 2.0 Here, reflecting lists in general. I was originally using t.IsAssignableFrom(typeof(IEnumerable)) to detect if a Property I was traversing supported the IEnumerable Interface. (And thus I could cast the object to it safely) However this code was not evaluating to True when the object is a BindingList<T>. Next I tried to use t.IsSubclassOf(typeof(IEnumerable)) and didn't have any luck either. Code /// <summary> /// Reflects an enumerable (not a list, bad name should be fixed later maybe?) /// </summary> /// <param name="o">The Object the property resides on.</param> /// <param name="p">The Property We're reflecting on</param> /// <param name="rla">The Attribute tagged to this property</param> public void ReflectList(object o, PropertyInfo p, ReflectedListAttribute rla) { Type t = p.PropertyType; //if (t.IsAssignableFrom(typeof(IEnumerable))) if (t.IsSubclassOf(typeof(IEnumerable))) { IEnumerable e = p.GetValue(o, null) as IEnumerable; int count = 0; if (e != null) { foreach (object lo in e) { if (count >= rla.MaxRows) break; ReflectObject(lo, count); count++; } } } } The Intent I want to basically tag lists i want to reflect through with the ReflectedListAttribute and call this function on the properties that has it. (Already Working) Once inside this function, given the object the property resides on, and the PropertyInfo related, get the value of the property, cast it to an IEnumerable (assuming it's possible) and then iterate through each child and call ReflectObject(...) on the child with the count variable.

  • Save a form in an XML file using Ajax and JSP

    - by novellino
    Hello, I want to create a simple form with a name and an email and save these data in an XML file. So far I found that using Ajax with jQuery is quite easy. So I used the usual code: //dataString have the values taken from the form var dataString = 'name='+ name + '&email=' + email; $.ajax({ type: "POST", url: "users.xml", data: dataString, dataType: "xml", success: function() { .... } }); If I understood well, in the url I should add the name of the XML file that will be created. When the user clicks a button I call the function with the Ajax request, and then I should call somewhere a function for generating the xml. I am using also two beans. One is for setting the elements of the user and the other is for saving the data in the XML. I am using the XStream library for the xml although I don't know if is the best solution. The problem now it that I can not connect all these together in order to save the data in the XML. Does anyone know what should I do? Thanks a lot!

In the book "the logical design of digital computers" by Montgomery Phister jr (published 1958), p54, it says: F11 = A + ~B has two interesting and useful associations, neither of them having much to do with computer design. The first is the logical notation of implication... The second is notation of inclusion... This may be expressed by a familiar looking relation, B < A; or by the statement "B is included in A"; or by the boolean equation F11= A + ~B = 1. My initial implementation was in C. Callbacks were given to the list to use for such operations. An example being a list of ints, and a struct containting two ints, min and max, for selection purposes. There, selection would be based upon B = A-min && B <= A-max. Using C++ and templates, how would you approach this after having implemented a generic list in C using void pointers and callbacks? Is using < as an over-ridden operator for such purposes... <ugh> evil? </ugh> (or by using a class B for the selection criteria, implementing the comparison by overloading ?)

  • Minimum privileges to read SQL Jobs using SQL SMO

    - by Gustavo Cavalcanti
    I wrote an application to use SQL SMO to find all SQL Servers, databases, jobs and job outcomes. This application is executed through a scheduled task using a local service account. This service account is local to the application server only and is not present in any SQL Server to be inspected. I am having problems getting information on job and job outcomes when connecting to the servers using a user with dbReader rights on system tables. If we set the user to be sysadmin on the server it all works fine. My question to you is: What are the minimum privileges a local SQL Server user needs to have in order to connect to the server and inspect jobs/job outcomes using the SQL SMO API? I connect to each SQL Server by doing the following: var conn = new ServerConnection { LoginSecure = false, ApplicationName = "SQL Inspector", ServerInstance = serverInstanceName, ConnectAsUser = false, Login = user, Password = password }; var smoServer = new Server (conn); I read the jobs by reading smoServer.JobServer.Jobs and read the JobSteps property on each of these jobs. The variable server is of type Microsoft.SqlServer.Management.Smo.Server. user/password are of the user found in each SQL Server to be inspected. If "user" is SysAdmin on the SQL Server to be inspected all works ok, as well as if we set ConnectAsUser to true and execute the scheduled task using my own credentials, which grants me SysAdmin privileges on SQL Server per my Active Directory membership. Thanks!

  • how to implement class with collection of string/object pairs so that an object can be returned with

    - by matti
    The values in a file are read as string and can be double, string or int or maybe even lists. An example file: DatabaseName=SomeBase Classes=11;12;13 IntValue=3 //this is required! DoubleValue=4.0 I was thinking something like this: public static T GetConfigValue(string cfgName) { // here we just return for example the value which could // be List[int] if parameter cfgName='Classes' // and LoadConfig was called with Dictionary containing // keyvaluepair 'Classes' / typeof(List[int]) } public static bool LoadConfig(Dictionary reqSettings, Dictionary optSettings) { foreach (KeyValuePair kvPair in reqSettings) { if (ReadCheckAndStore(kVPair, true)) return false; } foreach (KeyValuePair kvPair in reqSettings) { if (ReadCheckAndStore(kVPair, false)) return false; } return true; } private static bool ReadCheckAndStore(KeyValuePair kVPair, bool isRequired) { if (!ReadValue(kVPair.Key, out confValue) && isRequired) //req. IntValue !found return false; //here also have to test if read value is wanted type. //and if yes store to collection. } Thanks a lot & BR! -Matti PS. Additional issue is default values for optional settings. It's not elegant to pass them to LoadConfig in separate Dictionary, but that is an other issue...

  • Serializing a part of object graph

    - by Felix
    Hi all, I have a problem regarding Java custom serialization. I have a graph of objects and want to configure where to stop when I serialize a root object from client to server. Let's make it a bit concrete, clear by giving a sample scenario. I have Classes of type Company Employee (abstract) Manager extends Employee Secretary extends Employee Analyst extends Employee Project Here are the relations: Company(1)---(n)Employee Manager(1)---(n)Project Analyst(1)---(n)Project Imagine, I'm on the client side and I want to create a new company, assign it 10 employees (new or some existing) and send this new company to the server. What I expect in this scenario is to serialize the company and all bounding employees to the server side, because I'll save the relations on the database. So far no problem, since the default Java serialization mechanism serializes the whole object graph, excluding the field which are static or transient. My goal is about the following scenario. Imagine, I loaded a company and its 1000 employees from the server to the client side. Now I only want to rename the company's name (or some other field, that directly belongs to the company) and update this record. This time, I want to send only the company object to the server side and not the whole list of employees (I just update the name, the employees are in this use case irrelevant). My aim also includes the configurability of saying, transfer the company AND the employees but not the Project-Relations, you must stop there. Do you know any possibility of achieving this in a generic way, without implementing the writeObject, readObject for every single Entity-Object? What would be your suggestions? I would really appreciate your answers. I'm open to any ideas and am ready to answer your questions in case something is not clear.

  • XmlHttpRequest in a bookmarklet returns empty responseText on GET?

    - by David Eyk
    I'm trying to build a javascript bookmarklet for a special URL shortening service we've built at http://esv.to for shortening scripture references (i.e. "Matthew 5" becomes "http://esv.to/Mt5". The bookmarklet is supposed to do a GET request to http://api.esv.to/Matthew+5, which returns a text/plain response of http://esv.to/Mt5. The code for the bookmarklet itself looks like this (expanded for readability): var body = document.getElementsByTagName('body')[0], script = document.createElement('script'); script.type = 'text/javascript'; script.src = 'http://esv.to/media/js/bookmarklet.js'; body.appendChild(script); void(0); The code from http://esv.to/media/js/bookmarklet.js looks like this: (function() { function shorten(ref, callback) { var url = "http://esv.to/api/" + escape(ref); var req = new XMLHttpRequest(); req.onreadystatechange = function shortenIt() { if ( this.readyState == 4 && this.status == 200 ) { callback(req.responseText); }; }; req.open( "GET", url ); req.send(); }; function doBookmarklet() { var ref = prompt("Enter a scripture reference or keyword search to link to:", "") shorten(ref, function (short) { prompt("Here is your shortened ESV URL:", short); }); }; doBookmarklet(); })(); When called from http://esv.to itself, the bookmarklet works correctly. But when used on another page, it does not. The strange thing is, when I watch the request from Firebug, the response is 200 OK, the browser downloads 17 bytes (the length of the returned string), but the response body is empty! No error is thrown, just an empty responseText on the XmlHttpRequest object. Now, according to http://stackoverflow.com/questions/664689/ajax-call-from-bookmarklet, GET shouldn't violate the same origin policy. Is this a bug? Is there a workaround?
