• Show different sub-sets in edit view

  - by Martin R-L

  In the context of C# 4, ASP.NET MVC 2, and NHibernate; I've got the following scenario: Let's assume an entity Product that have an association to ProductType. In a product edit view; how do I implement that only a sub-set of the product's properties are shown in an elegant and DRY way? Use a product view model builder, and from different view models automagically generate the view with my own Html.EditorForModel() (including drop-downs and other stuff not out-of-the-box)? Attribute the properties of one view model and use the Html.EditorForModel() way aforementioned? Use one model, but implement different web controls (view strategies) (can it be done DRY?)? Something else entirely?

• NetBeans Web-Services Client Project - repeated WSDL parsing

  - by RedGrittyBrick

  I created a new project thus ... File, New Project... Java, Java Application. Right-click project icon in "Projects" tree-view panel. Choose New, Web Service Client... Specify WSDL file e.g. ( ) Project (*) Local file D:\temp\Foo\Bar.wsdl ( ) WSDL URL [Set Proxy...] client-style JAX-WS [ ] Generate Dispatch code It parsed the WSDL and generated lots of java files. I created a main class and used Netbeans to insert a WS client call Now whenever I run my code (Desktop app), it again parses the WSDL (which doesn't ever change) and regenerates about 78 java files and compiles them. How do I stop Netbeans performing this uneccessary and time-consuming action?

• Rails equivalent of respond_to |format| with a straight render

  - by brad

  I'm working with ActiveResource a lot so my service models are only using XML. Thus, I have no need for a respond_to block, I literally just render :xml => @model I can't however figure out how to render a 404 header using this. I've had to resort to respond_to, which I think adds a few unnecessary method calls. Here's what I'm using: respond_to do |format| if (record_found) render :xml => @some_record else format.xml{ head :not_found } end end but I just want something like render :xml => head :not_found which doesn't work. Can anyone tell me the proper syntax?

• Django equivalent for latest entry for each user

  - by paul-ogrady

  Hi, I'm surprised this question hasn't come up. Couldn't find much on the web. Using Entry.objects.latest('created_at') I can recover the latest entry for all Entry objects, but say if I want the latest entry for each user? This is something similar to an SQL latest record query. But how do I achieve this using the ORM? Here is my approach I'm wondering if it is the most efficient way to do what I want. First I perform a sub query: Objects are grouped by user and the Max (latest) created_by field is returned for each user (created_at__max) I then filter Entry objects based on the results in the subquery and get the required objects. Entry.objects.filter(created_at__in=Entry.objects.values('user').annotate(Max('created_at')).values_list('created_at__max')) or using a manager: class UsersLatest(models.Manager): def get_query_set(self): return Super(UsersLatest,self).get_query_set().filter(created_at__in=self.model.objects.values('user').annotate(Max('created_at')).values_list('created_at__max')) Is there a more efficient way? possibly without sub query? Thanks, Paul

• Getting a Method's Return Value in the VS Debugger

  - by Bullines

  Is it possible to get a method's return value in the Visual Studio debugger, even if that value isn't assigned to a local variable? For example, I'm debugging the following code: public string Foo(int valueIn) { if (valueIn > 100) return Proxy.Bar(valueIn); else return "Not enough"; } Since I'm not setting any local variables in Foo, and assuming I'm not setting a break point in whatever's calling Foo, is there a way to see what the return value is if I have a breakpoint inside of Foo (or another way)? I don't have much experience with the Autos or Intermediate windows, so I'm not sure if those are even a valid option or not.

• HMM for perspective estimation in document image, can't understand the algorithm

  - by maximus

  Hello! Here is a paper, it is about estimating the perspective of binary image containing text and some noise or non text objects. PDF document The algorithm uses the Hidden Markov Model: actually two conditions T - text B - backgrouond (i.e. noise) It is hard to understand the algorithm itself. The question is that I've read about Hidden Markov Models and I know that it uses probabilities that must be known. But in this algorithm I can't understand, if they use HMM, how do they get those probabilities (probability of changing the state from S1 to another state for example S2)? I didn't find anything about training there also in that paper. So, if somebody understands it, please tell me. Also is it possible to use HMM without knowing the state change probabilities?

• How to get ID of EditorFor with nested viewmodels in asp.net mvc 2

  - by Luke

  So I have two nested view models, CreditCard - BillAddress. I have a view, "EditBilling", that has EditorFor(CreditCard). The CreditCard EditorTemplate has EditorFor(BillAddress), and the BillAddress EditorTemplate has EditorFor(BillState). The end result is a select list with id "CreditCard_BillAddress_BillState". I need to reference this in javascript, thus need to know the ID. In other situations, with non-nested ViewModels, I have used the following code: $('#<%= ViewData.ModelMetadata.PropertyName %>_BillState') The problem here is that the ModelMetadata.PropertyName property is only aware of the current property, not the parent(s). So I end up with the following: $('#BillAddress_BillState') How does one go about getting the client ID of nested strongly typed helpers? Thanks in advance.

• How to cancel drop event in YUI drag & drop utility?

  - by gk

  We are using drag & drop utility between one source and multiple targets. We have a restriction that one of the target can only have one child element while the other ones can have multiple items. I have tried subscribing dragDropEvent of the proxy item and returning false in case the destination target has multiple child elements, with out much luck. var m = new YAHOO.example.DDList("dli" + j, 'documentSelection'); m.subscribe('dragDropEvent', function(e){ if (e.info == 'ulMasterDocument' && $('#ulMasterDocument').children().length > 1){ e.event.canceBubble = true; return false; } return true; }); Is this code correct? Or do i need to subscribe some other event? Thanks

• WCF, 4.0, Bidirectional...

  - by TomTom

  ...what options are there now with .NET 4.0, in a way that does support NAT for the client side (i.e. client behind NAT). I would prefer to use something HTTP based, but that is a weak condition - I think mid term I will have some non http communication outside WCF anyway, so proxy traversal is something I could delay. Pre .NET 4.0 there was the issue that basically the server-client channel would be opened from the server, which made NAT something non-traversable. Polling is not acceptable - we talk time sensitive information here. So, what are my options now?

• Difference between URLLIB2 call in IDLE and from Django?

  The following piece of code works as expected when running in a local install of django apache 2.2 fx = urllib2.Request(f); fx.add_header('User-Agent','Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.19 (KHTML, like Gecko) Chrome/1.0.154.36 Safari/525.19'); url_opened = urllib2.urlopen(fx); However when I enter that code into IDLE on the same machine I get the following error: url_opened = urllib2.urlopen(fx); File "C:\Python25\lib\urllib2.py", line 124, in urlopen return _opener.open(url, data) File "C:\Python25\lib\urllib2.py", line 387, in open response = meth(req, response) File "C:\Python25\lib\urllib2.py", line 498, in http_response 'http', request, response, code, msg, hdrs) File "C:\Python25\lib\urllib2.py", line 425, in error return self._call_chain(*args) File "C:\Python25\lib\urllib2.py", line 360, in _call_chain result = func(*args) File "C:\Python25\lib\urllib2.py", line 506, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) HTTPError: HTTP Error 407: Proxy Authentication Required Any ideas?

• Limit a user to view only associated records in rails

  - by trobrock

  I have an application with three Models (Profile - SubModel - SubSubModel) chained together with has many relationships. I am trying to limit a user, after logging in, to only retrieving records that are associated with their Profile. I am very new to rails and this is what I had been trying in the Profile model has_many :submodels, :conditions => {:profile_id => self.id} but this is returning an empty data set when calling with Profile.find_by_id(1).submodels, how else could I achieve what I am trying to do. Or should I handle this in the controller or view instead, I thought it sounded well suited for the model to handle this.

• Are JSF 2.x ViewScoped Beans Thread Safe?

  - by Mark

  I've been googling for a couple hours on this issue to no eval. WELD docs and the CDI spec are pretty clear regarding thread safety of the scopes provided. For example: Application Scope - not safe Session Scope - not safe Request Scope - safe, always bound to a single thread Conversation Scope - safe (due to the WELD proxy serializing access from multiple request threads) I can't find anything on the View Scope defined by JSF 2.x. It is in roughly the same bucket as the Conversation Scope in that it is very possible for multiple requests to hit the scope concurrently despite it being bound to a single view / user. What I don't know is if the JSF implementation serializes access to the bean from multiple requests. Anyone have knowledge of the spec or of the Morraja/MyFaces implementations that could clear this up?

• 3ds collada UV mapping problem in Papervision

  - by MonsieurOreilles

  Hi everyone, as I briefly explained in the title, my prblem concerns texturing a collada export in papervision. Basically I was exporting collada models from Cinema 4d with its uv map. I was able to see everything, but the texture was not displaying properly (hidden polygons). So I decided to try with 3dsMax. I used the same code to display the texture : var materials:MaterialsList = new MaterialsList(); var torusMaterial:BitmapFileMaterial = new BitmapFileMaterial("model/tex.png"); torusMaterial.precise = true; materials.addMaterial(torusMaterial, "ID1"); Again, I can see every elements, but this time my model uses only one pixel of my texture. So if I use a red texture and if I color only the pixel at the left bottom corner in green, all my model will be green. Any advice about how to properly wrap the texture around a 3ds export model ? Thank you.

• How can I equalize the heights of text input fields?

  - by David

  What is the best way to equalize the height of my <select..> elements and my <input type="text"..> elements? It's proving difficult because of differences in box-sizing models. Google Chrome's user agent stylesheet has this: select { -webkit-box-sizing: border-box; } ..whereas other text input fields use the content box model. Why the difference? Should I perhaps make all of my text-based input fields use the border-box model? BTW, I'm using standards-compliant mode (by using <!DOCTYPE html>).

• Rails STI: SuperClass Model Methods called from SubClass

  - by Karl

  I would like a little confirmation that I'm doing this correctly. Using rails single table inheritance I have the following models and class method: class PhoneNumber < ActiveRecord::Base def self.qual?(number) klass = self klass.exists?(:phone_number => phone_number) end end class Bubba < PhoneNumber end class Rufus < PhoneNumber end Bubba.qual?("8005551212") Tests pass and everything seems to work properly in rails console. Just wanted to confirm that I'm not headed for future trouble by using self in the superclass PhoneNumber and using that to execute class methods on subclasses from the parent. Is there a better way?

• Using the ASP.NET membership provider database with your own database?

  - by Shaharyar

  Hello everybody, We are developing an ASP.NET MVC Application that currently uses it's own databse ApplicationData for the domain models and another one Membership for the user management / membership provider. We do access restrictions using data-annotations in our controllers. [Authorize(Roles = "administrators, managers")] This worked great for simple use cases. As we are scaling our application our customer wants to restrict specific users to access specific areas of our ApplicationData database. Each of our products contains a foreign key referring to the region the product was assembled in. A user story would be: Users in the role NewYorkManagers should only be able to edit / see products that are assembled in New York. We created a placeholder table UserRightsRegions that contains the UserId and the RegionId. How can I link both the ApplicationData and the Membership databases in order to work properly / having cross-database-key-references? (Is something like this even possible?) All help is more than appreciated!

• AJAX with Web services and ASP.NET SessionState

  - by needhelp1

  We have an application which uses ScriptManager to generate a client-side proxy which makes AJAX calls to web services. The web services being invoked live in a separate appDomain(separate cluster altogether). The problem is that our application uses a State server for storing session. I want the web services to be able to access session also. First off, does anyone see anything wrong with the client making web service calls to a separate cluster(we're hoping this would be a better approach for scalability)? I was thinking that possibly anytime there is an update to the session dictionary in one appDomain, automatically update the session in the other appDomain also(referring to the web service appDomain, don't know how to do this, only theoretical). What do others think? Thanks!

• WCF - Network Cost

  - by Mubashar Ahmad

  Dear Devs I have a wcf service deployed on IIS with basicHttpBinding and aspNetCompatibilityEnabled=true I have a test client as well which invokes multiple service functions simultaneously. To check the performance of service call on client and server I calculated the Avg time it takes to complete a service request on client(in proxy code) and on server as well. after a test of 8 hrs (server and client were on the same machine) i came to know that average response time on client is around 34ms where as the Avg execution time on server is around 3ms so the difference is 31ms. I would like to know why every call is taking 31ms is it justified? and how can i reduce this?

• NHibernate mapping one table on two classes with where selection

  - by Rene Schulte

  We would like to map a single table on two classes with NHibernate. The mapping has to be dynamically depending on the value of a column. Here's a simple example to make it a bit clearer: We have a table called Person with the columns id, Name and Sex. The data from this table should be mapped either on the class Male or on the class Female depending on the value of the column Sex. In Pseudocode: create instance of Male with data from table Person where Person.Sex = 'm'; create instance of Female with data from table Person where Person.Sex = 'f'; The benefit is we have strongly typed domain models and can later avoid switch statements. Is this possible with NHibernate or do we have to map the Person table into a flat Person class first? Then afterwards we would have to use a custom factory method that takes a flat Person instance and returns a Female or Male instance. Would be good if NHibernate (or another library) can handle this.

• Naming convention for the primary key in a Table

  - by kwokwai

  Hi all, I am learning the Model relationship types in cakephp. I have built twotables and in one of the Table A, I got these fields in it: Table A {postID, topic, content} Table B {replyID, content, postID} And when I ran the web page, a bunch of error related to SQL popped up saying that cakephp couldn't find post_id. It is weird that I have already declared the $primaryKey to be using postID in the tableA.php under Models folder, but cakephp seemed want me to change the ID field to post_id instead of postID, because the error disappeared after I have changed the primaryKey to post_id. ANy ideas?

• Cloud e-mail and portal integration: experiences?

  - by Mark McLaren

  I am evaluating cloud e-mail solutions based upon: Google Apps for Education Microsoft Live@edu I work for a University and we currently have an institutional portal (based on uPortal). We currently have our local IMAP server and webmail client fully integrated with the portal. We would like to replicate the current portal e-mail experience with the new e-mail services. At present users can see a snapshot of their inbox in the portal and click through into the appropriate place in the webmail client. We expect that we need to solve similar problems when integrating with the cloud based e-mail solutions. We need to solve the single sign-on (SSO) problem. We need to be able to access the inbox messages on the users behalf. (e.g. proxy authentication) Does anybody have an experience or advice on this? Many thanks, Mark

• WCF over named pipes

  - by Christoph

  Hi I have a problem with following scenario: There is a windows service running which spawns several processes. These processes open a WCF service host over a named pipe binding. Now the parent windows service tries to ping (connect) to the child processes using the wcf proxy over the well known named pipe. This, however fails saying: "Endpoint not found" If I run the parent process as a console application it works fine. Any ideas? I was thinking about permissions but the child processes should inherit the permission of the service, besides they are in the same session as well. thanks, Christoph

• Windows disassembler: looking for a tool...

  - by SigTerm

  Hello. I'm looking for a (preferably free) tool that can produce "proper" disassembly listing from a (non-.NET) windows PE file (*.exe or *.dll). Important requirement: it should be possible to run the listing through a windows assembler (nasm, masm or whatever) and get working exe again (not necessarily identical to original one, but it should behave in the same way). Intended usage is adding new subroutines into existing code, when source is not available. Ideally, tool should be able to detect function/segment boundaries, API calls, and generate proper labels for jumps (I can live without labels for loops/jumps, though, but function boundary detection would be nice), and keep program resources/segments in place. I'm already aware of IdaPRO(not free), OllyDBG (useful for in-place hacking, doesn't generate disassembly listing, AFAIK), ndisasm (output isn't suitable for assembler), dumpbin (useful, but AFAIK, output isn't suitable for assembler) and "proxy dll" technique. Ideas? Or maybe there is a book/tutorial that explains some kind of alternative approach?
