• What causes a WPF ListCollectionView that uses custom sorting to re-sort its items?

  - by Drew Noakes

  Consider this code (type names genericised for the purposes of example): // Bound to ListBox.ItemsSource _items = new ObservableCollection<Item>(); // ...Items are added here ... // Specify custom IComparer for this collection view _itemsView = CollectionViewSource.GetDefaultView(_items) ((ListCollectionView)_itemsView).CustomSort = new ItemComparer(); When I set CustomSort, the collection is sorted as I expect. However I require the data to re-sort itself at runtime in response to the changing of the properties on Item. The Item class derives from INotifyPropertyChanged and I know that the property fires correctly as my data template updates the values on screen, only the sorting logic is not being called. I have also tried raising INotifyPropertyChanged.PropertyChanged passing an empty string, to see if a generic notification would cause the sorting to be initiated. No bananas. EDIT In response to Kent's suggestion I thought I'd point out that sorting the items using this has the same result, namely that the collection sorts once but does not re-sort as the data changes: _itemsView.SortDescriptions.Add( new SortDescription("PropertyName", ListSortDirection.Ascending));

• How do I switch between Navigation Controllers?

  - by RexOnRoids

  Situation: I have an Xcode project based on the "Navigation-Based-Application" template. So that means I have a SINGLE UINavigationController that manages a UIViewController. What I want To Do: What I want to do is add one more UINavigationController to my project -- and be able to switch back and forth between them. (I want to do this to make space for some seperate unrelated content so that it does not have a back button pointing back to the root view controller.) Question: How do I add one more UINavigationController to my project and switch between the two UINavigationControllers?

• SubSonic 3.0 - Save method with all columns as parameters?

  - by Todd Menier

  Hi, Just getting started with SubSonic. I'm using the Repository pattern, so my domain objects are totally seperate, and SubSonic-generated classes are used only in my data access layer. I'm wondering if a template exists that will give me a Save method (Insert/Update) that requires all table column values as parameters. My thinking is that since I need to do the mapping work manually, at least if my database schema changes (ie, a new column is added), I won't forget to add a corresponding mapping, since the auto-generated method signature would change and the compiler would catch it. I've considered messing with the T4 templates to add this feature, but thought I'd check if this already exists somewhere before I head down that path. Thanks in advance.

• Why would the assignment operator ever do something different than its matching constructor?

  - by Neil G

  I was reading some boost code, and came across this: inline sparse_vector &assign_temporary(sparse_vector &v) { swap(v); return *this; } template<class AE> inline sparse_vector &operator=(const sparse_vector<AE> &ae) { self_type temporary(ae); return assign_temporary(temporary); } It seems to be mapping all of the constructors to assignment operators. Great. But why did C++ ever opt to make them do different things? All I can think of is scoped_ptr?

• How to set the content of the $script_for_layout in cakephp?

  - by sipiatti

  Hi, I am learning cakephp in an autodidact manner and I am a complete newbie :) I am creating a simple application. Some logic work so now I going to dive into designing views and layouts. I read the docs and the tutorial but I could not find where to set the content of $script_for_layout. Especially I want to set a $html-css to create link in pages to the stylesheet. I found out that I could do it in directly in the layout template but I would like to create the same link in all pages/views/layouts to the stylesheet so I hope there is a simple way, and avoid to do this in all layouts and/or controllers

• Display archive posts in Wordpress

  - by missmonkee

  I am looking to display archives pages as a normal posts page... So, a posts page with a secondary navigation showing: Latest posts / Last month / Last year / Older On each of those pages, I would like to display a summary of each post just like the standard latest news page. When you click through you get to the full post. For each of menu items I have created seperate page templates such as archives_month.php, Then in the template instead of using For the LAST MONTH page. But I now cannot use this for LAST YEAR and OLDER posts. Can anyone help me? I've looked into a number of different ways to do it but on some blogs it's not clear and most people just retrieve a list of archives rather than displaying the posts. Thanks in advance. Mel

• Incorporate Wordpress into Kohana 3

  - by alex

  I now need to make a Kohana 3 site have a Wordpress blog. I've seen Kerkness' Kohana For Wordpress, but it seems to be the opposite of what I want. Here are the options I have thought of Style a template to look exactly like the Kohana site (time consuming, non DRY and may not work) Include the blog within an iframe (ugly as all hell) cURL the Wordpress pages in. This of course means I will need to create layers between comment posting, etc, which sounds like too much work. Is there any way I can include a Wordpress blog within an existing Kohana application? Do you have any suggestions? Thanks Update Forgot to mention I have already programmed a model in Kohana to open pages based on their slug. Now I want to put blog content in there, and have the comments and other bits work. I also have installed WP e-Commerce and am wondering if there is any chance I can get that to work.

• Automatically number items in a wpf listbox

  - by evan

  I have a person class with two properties, Name an Age. I know how to use databinding to display a collection of person in a wpf list box and how to modify the listitemtemplate to customize how each person is displayed. Now I'd like to number each person on the list according to the order they appear on the list (which could change as the the items were sorted via name or age in the display). Is there a way to do that with the item template so instead of having a list like Rob - 14 John - 56 Suzy - 32 it would be 1) Rob - 14 2) John - 56 3) Suzy - 32 Basically i'd like to do something like: <ListView.ItemTemplate> <DataTemplate> <WrapPanel> **<TextBlock Text="{Binding CurrentPositionInList}" />** <TextBlock Text="{Binding Path=Name}" /> <TextBlock Text="{Binding Path=Age}" /> </WrapPanel> </DataTemplate> Thanks in advance!

• WPF,XAML: How to set the ZIndex of a particular control to the topmost.

  - by Sudhakar Singh

  how do i set any control to the topmost of the screen. For e.g. i have a textblock in a datatemplate or a hierarchichal data template..etc... now i would like to set this textblock to the topmost on mouseover. Setting the Grid.ZIndex value to 1 in the trigger for IsMouseOver doesn't work many times. In order to do that i set the ZIndex value for all the contols to -1 in the window. it worked in one scenario but doesn't work other times. If anyone can get me the details of ZIndex and how to set the control to the topmost without worrying about the other controls, it would be of great help. Note: setting the value of ZIndex to a higher value e.g. 99999 also doesn't work.

• Feature activate via UI but does not show in the Libraries and Lists

  - by Justin Cullen

  I am really hating SharePoint as there are hardly any good/concrete documentation. I developed custom List "MainCatalog" with few columns (not site columns). Create features and elements with MOSS feature builder at Site collection level so scope="site" installed via stsadm activated via UI "went to site collection website", Site Setting Site collection Feature (and saw my custom list "MainCatalog") and was able to activate. then went to "mySiteCollection Site Settings Site Libraries and Lists " My list is showing But it shows in the "mySiteCollection Create Custom Lists "MainCatalog" I guess it's showing there as a template... But my intention is to deploy this list from development to test environment. EXTREMELY STRESSED. I AM ON THIS FOR LAST 8 DAYS.....

• Get C# Templates For VS 2008 Shell

  - by Onorio Catenacci

  I've got VS 2008 Shell Integrated mode; I've got F# 2.0 on that installation. Till now this has worked fine for me because I've been hacking at F# code. Now though, I want to install Intellifactory's WebSharper. It looks like the Intellifactory templates assume that C# templates will be available because while it will create the F# portion of the solution it will not create the Web project in the solution with the complaint A problem was encountered creating the sub project 'Web Application'. The template specified cannot be found. Is there any place where I can get the C# stuff to add to this instance of VS 2008 Shell? Apologies in advance if this is a dup question but I've googled without much luck and I don't seem to find this here either. I've seen that about devenv /installvstemplates but that also fails with a message about needing to elevate privileges (which is odd since I try it under an admin user).

• TabItems from View collection

  - by byte

  I am using MVVM. I have a tab control. I will have a collection of items. I want to display each of this item in the collection as a tab item. The view in each tab item is different and may have its own viewmodel. How do I achieve this? E.g. I have 3 items in the collection. The Tab item template contains an ItemControl. I would like to now have 3 Tabs created and the ItemControls inside each tabitem may be showing different views. One way I could do is have a single view and viewmodel for each item. Now based on some condition the View will display different UI elements and behave differently. But I am afraide this will make the view quite complex over a period of time.

• WordPress: don't show 404 when no posts exist

  - by philfreo

  Currently there is a bug in WordPress if you have a Posts Page set under: Settings-Reading-A Static Page-Posts Page If there are posts, than the page (e.g. with a slug called news) displays the post, and uses index.php from the theme. But, with this configuration, if there are no posts, then it calls the theme's 404 page. This is definitely a bug, and has been submitted (Ticket #10822). It should be letting index.php show whatever it wants upon !have_posts(), but right now the page doesn't seem to be called at all. My question is: is there a workaround for this bug without modifying core wp files? I'd be open to a plugin, theme changes, a custom page template, htaccess changes, etc.

• Implementing DRY Forms

  - by virtualeyes

  Getting into Play 2.0, overall, blown away, great stuff. Anyway, wondering how one can achieve DRY forms in Play? If you look at the create & edit examples in the Computer Database Sample, you'll see that the form elements are repeated. With just 4 fields (in the sample form), no big deal, but when you're dealing with large, complex forms and/or handling many CRUD models, the duplication becomes a bigger maintenance issue. On the binding end ( form.bindFromRequest and form.fill(Foo) ), the implementation is so elegant for create/edit operations; is there a corresponding solution in the template layer?

• Authkit - deferring action to HTTP response to client application

  - by jon

  Form, Redirect and Forward all send an unauthenticated user to a Form on a login page specified within an Authkit middleware application. I'd like to allow a client application to request a service via XHR and then present a custom 'client side' form if a HTTP status code of 401 is returned, which would then post to Authkit for authentication until valid authentication/authorization occured. Specifically, 1) a jquery $.get request might request a resource. 2) if an Authkit cookie check confirmed previous authorization the content would be returned. 3) if not I would like Authkit to simply return the '401 response' (and not redirect to another page, or return a form template) where a client side exception handler would notify the user and present an authentication form. Can Authkit work like this?

• In the following implementation of static_strlen, why are the & and parentheses around str necessary

  - by Ben

  If I change the type to const char str[Len], I get the following error: error: no matching function for call to ‘static_strlen(const char [5])’ Am I correct that static_strlen expects an array of const char references? My understanding is that arrays are passed as pointers anyway, so what need is there for the elements to be references? Or is that interpretation completely off-the-mark? #include <iostream> template <size_t Len> size_t static_strlen(const char (&str)[Len]) { return Len - 1; } int main() { std::cout << static_strlen("oyez") << std::endl; return 0; }

• Is Boost.Tuple compatible with C++0x variadic templates ?

  - by Thomas Petit

  Hi, I was playing around with variadic templates (gcc 4.5) and hit this problem : template <typename... Args> boost::tuple<Args...> my_make_tuple(Args... args) { return boost::tuple<Args...>(args...); } int main (void) { boost::tuple<int, char> t = my_make_tuple(8, 'c'); } GCC error message : sorry, unimplemented: cannot expand 'Arg ...' into a fixed-length argument list In function 'int my_make_tuple(Arg ...)' If I replace every occurrence of boost::tuple by std::tuple, it compiles fine. Is there a problem in boost tuple implementation ? Or is this a gcc bug ? I must stick with Boost.Tuple for now. Do you know any workaround ? Thanks.

• Varnish server in front of nginx server with multiple virtualhosts

  - by Garreth 00

  I have tried to search for a solution for this, but can't find any documentation/tips on my specific setup. My setup: Backendserver: ngnix: 2 different websites (2 top domains) in virtualenv, running gunicorn/python/django Backendserver hardware(VPS) 2gb ram, 8 CPU Databaseserver: postgresql - pg_bouncer Backendserver hardware (VPS) 1gb ram, 8 CPU Varnishserver: only running varnish Varnishserver hardware (VPS) 1gb ram, 8 CPU I'm trying to set up a varnish server to handle rare spike in traffic (20 000 unique req/s) The spike happens when a tv program mention one of the sites. What do I need to do, to make the varnish server cache both sites/domains on my backendserver? My /etc/varnish/default.vcl : backend django_backend { .host = "local.backendserver.com"; .port = "8080"; } My /usr/local/nginx/site-avaible/domain1.com upstream gunicorn_domain1 { server unix:/home/<USER>/.virtualenvs/<DOMAIN1>/<APP1>/run/gunicorn.sock fail_timeout=0; } server { listen 80; listen 8080; server_name domain1.com; rewrite ^ http://www.domains.com$request_uri? permanent; } server { listen 80 default_server; listen 8080; client_max_body_size 4G; server_name www.domain1.com; keepalive_timeout 5; # path for static files root /home/<USER>/<APP>-media/; location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; if (!-f $request_filename) { proxy_pass http://gunicorn_domain1; break; } } } My /usr/local/nginx/site-avaible/domain2.com upstream gunicorn_domain2 { server unix:/home/<USER>/.virtualenvs/<DOMAIN2>/<APP2>/run/gunicorn.sock fail_timeout=0; } server { listen 80; listen 8080; server_name domain2.com; rewrite ^ http://www.domains.com$request_uri? permanent; } server { listen 80; listen 8080; client_max_body_size 4G; server_name www.domain2.com; keepalive_timeout 5; # path for static files root /home/<USER>/<APP>-media/; location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; if (!-f $request_filename) { proxy_pass http://gunicorn_domain2; break; } } } Right now, If I try the Ip of the varnishserver I only get served domain1.com. Would everything be correct if I change the DNS of the two domain to point to the varnishserver, or is there extra setup before it would work? Question 2: Do I need a dedicated server for varnish, or could I just install varnish on my backendserver, or would the server run out of memory quick?
