• CMS common Architecture

  - by Shalan

  Hi there, I know this is a weird question to ask, but I would like to know if there is any documentation/blog-article out there that explains the architecture of a Website content management system? More particularly, I am interested to learn more about how "widgets" are implemented. I can't remember which system it was that I've seen tis one, but in the "Page Layout view" it had the ability to allow the end user to select a widget (thumbnail gallery, contact form, etc) from a list, and drag and drop it onto custom areas of the page. I know that this is not directly a programming question, but please could I seek advice/feedback on this. Thanks!

• iPhone: how do I set up a clear window-size "blocker view"?

  - by Ben

  I feel like this should be obvious to me, but for some reason I can't figure this out. I have a navigation interface with nav bar, tool bar, and primary view. Sometimes the user takes an action that causes a progress indicator to appear in the middle of the view. While the progress indicator (which is a custom UIView) in spinning in the middle, I want no touch input to be allowed to go to any of the underlying interface (main view, nav bar, toolbar, etc). But this doesn't seem trivial. I've tried (and failed) to create a simple view whose only job is to swallow touch input and use it as a window subview-- no dice, it never gets the touch events (and yes, it does have userInteractionEnabled). I've tried to bolt it on as a transparent modal view controller, but those don't seem to ever be transparent. Thoughts? What am I missing? Thanks!

• Separation of static and dynamic content in Java EE applications

  - by Dan

  We work with IBM products and we typically use IBM Http Servers (read Apache) as a reverse proxy for our application servers. For performance reasons we serve static content (.gif, .jpg, .css, .html etc.) from our http servers, to ease the burden a bit from the application server. So far, we have to distribute files to http server and configure it manually (writing custom scripts at best.) The problem is the effort needed to keep everything in synch, especially when you need to update the app. Does any Java EE product support this “out of the box”? Is there a way to have application server do this automatically, like in cluster configuration for example, where master node is in charge of distributing the application to other nodes and for keeping everything in synch.

• Put logic behind generated LinqToSql fields

  - by boris callens

  In a database I use throughout several projects, there is a field that should actually be a boolean but is for reasons nobody can explain to me a field duplicated over two tables where one time it is a char ('Y'/'N') and one time an int (1/0). When I generate a datacontext with LinqToSql the fields off course gets these datatypes. It would be nice if I don't have to drag this stupid choice of datatype throughout the rest of my application. Is there a way to give the generated classes a little bit of logic that just return me return this.equals('Y'); and return this==1; Preferably without having to make an EXTRA field in my partial class. It would be a solution to give the generated field a totally different name that can only be accessed through the partial class and then generate the extra field with the original name with my custom logic in the partial class. I don't know how to alter the accesibility level in my generated class though.. Any suggestions?

• msbuild for .NET 3.5 issue with csla and System.Linq

  - by Sash

  This is a weird problem. I am trying to build a .NET 3.5 solution with msbuild. I generally write custom build scripts for this, and when I tried this time to build a simple .NET assembly which internally uses CSLA, it started giving me Linq errors. However, if I build the proj file via msbuild (command line), it seems to build just fine. No issues at all. Anyone else encounter this issue...and if yes, how do i fix this? Thanks, Sashidhar Kokku

• How to isolate data per customer, Django powered website

  - by Sawwy

  I have recently started learning python and django and working on a project that includes building a website for collecting information from customers. I am currently trying to figure out best way to isolate the customer data (collected information is sensitive and should only be accessible by customer and the service provider). I found this post Postgresql - one database for everyone, or one-database per customer and my question is that can I automate the model inheritance with customer creation via admin? To be specific, when save() is called for adding customer via django admin, this should create the customer specific tables (create a new set of tables with 'company_name' -prefix). For more information of the environment, I have extended the basic user registration with custom UserProfile adding 'company' and 'role' fields for each user. Upon login, the 'company' of the user will be checked to filter out tables without the 'company_name' prefix. 'Role' will further filter the which company-specific tables and set rights (view, edit). will appreciate any suggestions if more elegant methods could be used to solve the data isolation problem than model inheritance.

• Python - which multi platform GUI framework to use?

  - by Iacopo

  Hi, I've written a Python GUI application and made it run on Linux, Windows and Mac. The framework I'm using is PyGtk. The final result is not really good: the application looks horrible on Mac, and it is not really 'native' neither on Windows. Furthermore on Mac the windows' behavior is sometimes wrong, with modal dialogs appearing below the main windows. I've explored other frameworks and I've found that a porting may be really hard: PyQt it is huge, difficult to install and to distribute under Mac; PyGui is poor: I need tables and tree views at least; wxPython state explicitly that you have to use a custom python build for Mac Tkinter: didn't check it, only have the impression that it is obsolete I know this question may appear similar to http://stackoverflow.com/questions/394039/which-python-gui-framework but in that thread the portability issue is not really taken in account. Windows and Mac are a must, since most of my user have that systems. Can you also suggest some books?

• ASP.NET: CSS friendly calendar control

  - by pbz

  I'm using the built-in Calendar control. It works, but in a few places the way the HTML is rendered is broken or not CSS-friendly and unfortunately cannot be changed (it's hard coded). I was hoping they would fix this in .NET 4.0, but as far as I can tell the Calendar control hasn't been changed at all. Also, as far as I know, there's no CSS adapter for the Calendar control. So, I would need a control that would: Allow me to customize the content of each cell (like OnDayRender works) Allow me to assign CSS classes to any HTML it may render Not render anything automatically that cannot be turned off, except layout code No auto-postback or auto-JS code (I can handle these by hand using simple links or custom JS calls) Basically a simple calendar view control that would give me full rendering control. What would you recommend? Thanks!

• SQL 2005 w/ C# optimal "Paging"

  - by David Murdoch

  When creating a record "grid" with custom paging what is the best/optimal way to query the total number of records as well as the records start-end using C#? SQL to return paged record set: SELECT Some, Columns, Here FROM ( SELECT ROW_NUMBER() OVER (ORDER BY Column ASC) AS RowId, * FROM Records WHERE (...) ) AS tbl WHERE ((RowId > @Offset) AND (RowId <= (@Offset + @PageSize)) ) SQL to count total number of records: SELECT COUNT(*) FROM Records WHERE (...) Right now, I make two trips to the server: one for getting the records, and the other for counting the total number of records. What is/are the best way(s) to combine these queries to avoid multiple DB trips?

• Referencing a control inside a XSL Template from code behind ?

  - by Mina Samy

  Hi all I have a custom NewItem.aspx that I made by creating a new aspx from the exisiting one I wanted to put a control in a row inside the XSL Template like this <asp:DropDownList ID="ddlSectors" AutoPostBack="true" runat="server" __designer:bind="{ddwrt:DataBind('i',ddlSectors,'SelectedValue','TextChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Sector')}"> </asp:DropDownList> <!--<SharePoint:FormField runat="server" id="ff7{$Pos}" ControlMode="New" FieldName="Sector" __designer:bind="{ddwrt:DataBind('i',concat('ff7',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Sector')}"/>--> <SharePoint:FieldDescription runat="server" id="ff7description{$Pos}" FieldName="Sector" ControlMode="New"/> Now I want to reference ddlSectors from my code library but it always throws an object reference not set to an instatnce of an object. I believe that this is becuase the control is inside the XSL template. so is there any workaround for this ? thanks

• ASP.NET MVC - Add XHTML into validation error messages

  - by Neil

  Hi, Just starting with ASP.Net MVC and have hit a bit of a snag regarding validation messages. I've a custom validation attribute assigned to my class validate several properties on my model. When this validation fails, we'd like the error message to contain XHTML mark-up, including a link to help page, (this was done in the original WebForms project as a ASP:Panel). At the moment the XHTML tags such as "< a ", in the ErrorMessage are being rendered to the screen. Is there any way to get the ValidationSummary to render the XHTML markup correctly? Or is there a better way to handle this kind of validation? Thanks

• Per query relevance elevation for solr?

  - by plusplus

  I want to tune the relevance of solr search results on a per user basis - based on the number of times the user has clicked through a result before. Frequently hit items FOR THAT USER should rise to the top of their search results. Is there a way to provide custom boost/elevation for particular document ids on the query? I'm thinking in the order of ~100s of particular documents to elevate. The elevation should have no effect if the rest of the query doesn't find those documents. Alternatively, if this isn't possible, what is a sane way for setting up an alternative indexing approach that would make this possible? Could I add a field per user in the index to store their scores? I'm thinking in the order of 1000 users. The major drawback of that approach is the number of times a document would need to be reindexed (i.e. each time it was used by the user).

• How to set skin at runtime in Flex 4

  Hi, I have a bunch of custom controls based on a SkinnableContainer. When adding the control at design time, I can specify a skin by using the skinClass attribute on the tag.

• Can a single solution hold projects from multiple repositories?

  - by cyclotis04

  I've begun setting up SVN repositories to store my code, and am wondering if a single Visual Studio solution can have projects from multiple repositories. I have a shared library with different helper functions, generic custom controls, etc, that are used by multiple projects, and hosted in its own repository. Then I have my project repository, which contains all of the program-specific code such as forms, etc. I know I could copy the shared library into the program's repository, then copy them back when I make changes, but I'd much rather keep them in different repositories so I can hit "Commit" and the general library commits to it's repository, and the program code commits to it. I'm currently using AnkhSVN, but if it's possible with other tools, I'll look into it. Preemptive clarification for all the "just use one repository" answers: The shared library is hosted in an online repository, viewable by anyone, but the program code is proprietary and resides on our office servers, so they need different repositories.

• Is there a built-in way to determine the size of a WCF response?

  - by jaminto

  Before a client gets the full payload of the web request, we'd like to first send it a measurement of the size of the response it will get. If the response will be too large, the client will present a message to the user giving them the option to abort the operation. We can write some custom code to preload the response on the server, determine the size, and then pass it on to the client, but we'd rather not if there's another way to do it. Does anyone know if WCF has any tricky way to do this? Or are there any free third party tools out there that will accomplish this? Thanks.

• Umbrella websites with Microsites & Blogs - recommendations

  - by pingu

  Hi guys, I'm in the process of scoping a solution for an events organisation. Their main website features information about them and blog entries etc, but they hold major events which require microsites (domain.com/event). The microsites all have a different look-and-feel, different nav structure, and custom content-managed components. The one thing that's common across everything is the blog - it will have a category for each event under which users can post. How would you guys implement this? The solution needs to be PHP, and my initial thought was CodeIgniter but if possible I'd like to avoid building the blog functionality - so I guess I could integrate it with EE or Wordpress. If anyone has any other suggestions they would be most appreciated.

• I get a 400 Bad Request error while using django-piston

  - by Cheezo

  Hello, I am trying to use Piston to provide REST support to Django. I have implemented my handlers as per the documentation provided . The problem is that i can "read" and "delete" my resource but i cannot "create" or "update". Each time i hit the relevant api i get a 400 Bad request Error. I have extended the Resource class for csrf by using this commonly available code snippet: class CsrfExemptResource(Resource): """A Custom Resource that is csrf exempt""" def init(self, handler, authentication=None): super(CsrfExemptResource, self).init(handler, authentication) self.csrf_exempt = getattr(self.handler, 'csrf_exempt', True) My class (code snippet) looks like this: user_resource = CsrfExemptResource(User) class User(BaseHandler): allowed_methods = ('GET', 'POST', 'PUT', 'DELETE') @require_extended def create(self, request): email = request.GET['email'] password = request.GET['password'] phoneNumber = request.GET['phoneNumber'] firstName = request.GET['firstName'] lastName = request.GET['lastName'] self.createNewUser(self, email,password,phoneNumber,firstName,lastName) return rc.CREATED Please let me know how can i get the create method to work using the POST operation?

• jQuery jPicker path issues when used in WordPress Theme Options

  - by Scott B

  Anyone with experience using jPicker colorpicker in a WordPress Custom Theme options panel. I believe that the default path for the jPicker resources is /jPicker/ relative to the location the js file appears, however, I'm not seeing the picker.gif icon, so I tried changing the path in the js file like so... images:{clientPath:"../wp-content/themes/myTheme/images/" Everything else appears to be working at first load. My bound input field's background color is the same as the currently selected color. However, the picker.gif icon is missing. Where it should appear, I've just got a 2px wide by 20px tall color element (looks like a div perhaps).

• JSF actionListener is called multiple times from within HtmlTable

  - by Rose

  I have a mix of columns in my htmltable: 1 column is an actionlistener, 2 columns are actions and other columns are simple output. <h:dataTable styleClass="table" id="orderTable" value="#{table.dataModel}" var="anOrder" binding="#{table.dataTable}" rows="#{table.rows}" <an:listenerColumn backingBean="${orderEntry}" entity="${anOrder}" actionListener="closeOrder"/ <an:column label="#{msg.hdr_orderStatus}" entity="#{anOrder}" propertyName="orderStatus" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="editOrder" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="viewOrder"/ .... I'm using custom tags, but it's the same behavior if I use the default column tags. I've noticed a very strange effect: when clicking the actionlistenercolumn, the actionevent is handled 3 times. If I remove the 2 action columns then the actionevent is handled only once. The managed bean has sessionscope, bean method: public void closeOrder(ActionEvent event) { OrdersDto order; if ((order = orderRow()) == null) { return; } System.out.println("closeOrder() 1 "); orderManager.closeOrder(); System.out.println("closeOrder() 2 "); } the console prints the'debug' text 3 times.

• Using a map with set_intersection

  - by Robin Welch

  Not used set_intersection before, but I believe it will work with maps. I wrote the following example code but it doesn't give me what I'd expect: #include <map> #include <string> #include <iostream> #include <algorithm> using namespace std; struct Money { double amount; string currency; bool operator< ( const Money& rhs ) const { if ( amount != rhs.amount ) return ( amount < rhs.amount ); return ( currency < rhs.currency ); } }; int main( int argc, char* argv[] ) { Money mn[] = { { 2.32, "USD" }, { 2.76, "USD" }, { 4.30, "GBP" }, { 1.21, "GBP" }, { 1.37, "GBP" }, { 6.74, "GBP" }, { 2.55, "EUR" } }; typedef pair< int, Money > MoneyPair; typedef map< int, Money > MoneyMap; MoneyMap map1; map1.insert( MoneyPair( 1, mn[1] ) ); map1.insert( MoneyPair( 2, mn[2] ) ); map1.insert( MoneyPair( 3, mn[3] ) ); // (3) map1.insert( MoneyPair( 4, mn[4] ) ); // (4) MoneyMap map2; map1.insert( MoneyPair( 3, mn[3] ) ); // (3) map1.insert( MoneyPair( 4, mn[4] ) ); // (4) map1.insert( MoneyPair( 5, mn[5] ) ); map1.insert( MoneyPair( 6, mn[6] ) ); map1.insert( MoneyPair( 7, mn[7] ) ); MoneyMap out; MoneyMap::iterator out_itr( out.begin() ); set_intersection( map1.begin(), map1.end(), map2.begin(), map2.end(), inserter( out, out_itr ) ); cout << "intersection has " << out.size() << " elements." << endl; return 0; } Since the pair labelled (3) and (4) appear in both maps, I was expecting that I'd get 2 elements in the intersection, but no, I get: intersection has 0 elements. I'm sure this is something to do with the comparitor on the map / pair but can't figure it out.

• [Android SDK] Text-To-Speech addSpeech not working properly

  - by arcoraven

  Hi, I'm trying to get my Android app to play a .wav file recording of the word "Spinach Salad" whenever it sees that phrase being spoken by TTS. Here's the relevant code: spinach_salad.wav is located in /res/raw prodName = "Spinach Salad" mTts.addSpeech(prodName, "com.example.textextractor", R.raw.spinach_salad); ...and later in the code: mTts.speak("blah blah blah " + prodName, TextToSpeech.QUEUE_ADD, null); I've also tried: mTts.speak("blah blah blah Spinach Salad", TextToSpeech.QUEUE_ADD, null); and mTts.speak("blah blah blah", TextToSpeech.QUEUE_ADD, null); mTts.speak(productName_str, TextToSpeech.QUEUE_ADD, null); In both cases, I'm just hearing the TTS synthesized audio, rather than my custom .wav file. (On a related note, the last chunk of code sometimes speaks out of order, saying the second line before the first).
