• How to create an Entity Framework model from an existing SQLite database in Visual Studio 2008?

  - by splattne

  I've installed the System.Data.SQLite ADO.NET Provider from http://sqlite.phxsoftware.com/. I can connect to the database from within Visual Studio, I can open table schemas, views etc. I'd like to use an existing SQLite database to create an Entity Framework model in Visual Studio 2008. When I try to create a new ADO.NET Entity Data Model (.edmx) file using the wizard, the existing SQLite connection is not in the list though. Also, it's not possible to create a SQLite connection because there is no provider for SQLite. It only lists SQL Server, SQL Server file and SQL Server Compact 3.5. Any idea how to solve this problem?

• Sphinx PHP Geodist problems

  - by James

  Below is my PHP function to call nearby points using Sphinx for MySQL. There are hundreds of thousands of nearby points which to what I can tell, are being indexed by Sphinx, but simply fails silently when searching with Sphinx. Other Sphinx queries I run against other indexes work completely fine. function nearby($latitude, $longitude, $radius) { global $sphinx; $sphinx->SetMatchMode(SPH_MATCH_ALL); $sphinx->SetArrayResult(true); $sphinx->SetLimits(0, 1000); $sphinx->SetGeoAnchor('latitude', 'longitude', (float) deg2rad($latitude), (float) deg2rad($longitude)); $circle = (float) $radius * 1.609344; $sphinx->SetFilterFloatRange('@geodist', 0.0, $circle); $matches = $sphinx->Query('', 'geo'); return $matches; } $nearby = nearby($latitude, $longitude, 10000); var_dump($nearby); This, when called with valid latitude and longitude co-ords and a very large radius for debugging produces: bool(false) Below is my sphinx.conf covering the geo part: source geo { type = mysql sql_host = 127.0.0.1 sql_user = user sql_pass = pass sql_db = db sql_port = 3306 sql_query_pre = set names utf8 sql_query_pre = set session query_cache_type=OFF sql_query = SELECT id,city,region,country,radians(longitude) AS longitude, radians(latitude) AS latitude FROM points; sql_attr_float = longitude sql_attr_float = latitude sql_ranged_throttle = 0 sql_query_info = SELECT * FROM points WHERE id = $id } index geo { source = geo path = /var/data/geo docinfo = extern #mlock = 0 #morphology = none min_word_len = 1 charset_type = utf-8 #charset_table = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F ignore_chars = U+00AD html_strip = 0 enable_star = 0 } indexer { mem_limit = 1024M } searchd { port = 3312 log = /var/log/searchd.log query_log = /var/log/query.log read_timeout = 5 max_children = 5 pid_file = /var/log/searchd.pid max_matches = 10000 seamless_rotate = 1 preopen_indexes = 0 unlink_old = 1 }

• Java method for android:layout_gravity

  - by André Leitão

  Hi folks, I would like to know if is there a way to call android:layout_gravity property from a java method. I didn't found any method in Android documentation to do it. This is the picture of the layout I want to implement: I know to do it through xml, as following: <FrameLayout xlmns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:layout_gravity="left|center_vertical" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="<" /> <Button android:layout_gravity="right|center_vertical" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text=">" /> </FrameLayout> But in my situation, I need to do it through Java code, because I'll implement another layout views dinamically. To avoid merging xml layout with Java code, I would prefer make all layout using Java. Can you help me? Thanks. André Leitão

• MVC2 jQuery Validation & Custom Business Objects

  - by durilai

  I have an application that was built with MVC1 and am in the process of updating to MVC2. I have a custom DLL and BLL, of which the model objects are custom business objects that reside in a separate class library. I was using this validation library in MVC1, which worked great. It worked great, but I want to eliminate the extra plugins and use what is available. Rather than use the Enterprise Library validation attributes I have converted to using DataAnnotations and want to use jQuery validation as the client side validation. My questions are: 1) Is the MicrosoftMvcJQueryValidation JS file still required, where do I download. 2) How to you automate the validation to views that do not have models, IE Membership sign in page? 3) How to you add model errors in a custom business layer. Thanks for any help or guidance.

• Error when starting a tab activity in Android?

  - by ATDeveloper

  I followed the directions verbatim in this Android tutorial, copying/pasting the code from the site to my app. http://developer.android.com/resources/tutorials/views/hello-tabwidget.html However, when I try to run in the Android emulator, I get the error: "The application Hello Tab Widget has stopped unexpectedly. Please try again." I tried debugging by introducing a breakpoint in the first line of the onCreate method, but the error occurs before the breakpoint is even hit. Any idea of what is going wrong, or any other way I can debug this issue? I am using Eclipse.

• Generate POCO classes in different project to the project with Entity Framework model

  - by Max

  I'm trying to use the Repository Pattern with EF4 using VS2010. To this end I am using POCO code generation by right clicking on the entity model designer and clicking Add code generation item. I then select the POCO template and get my classes. What I would like to be able to do is have my solution structured into separate projects for Entity (POCO) classes and another project for the entity model and repository code. This means that my MVC project could use the POCO classes for strongly typed views etc and not have to know about the repository or have to have a reference to it. To plug it all together I will have another separate project with interfaces and use IoC. Sounds good in my head I just don't know how to generate the classes into their own project! I can copy them and then change the namespaces on them but I wanted to avoid manual work whenever I change the schema in the db and want to update my model. Thanks

• Bug Running Android Tutorial HelloTabWidget under SDK 1.5: "setCurrentTag(getIntent())"

  - by Matt J.

  does not compile. Indeed: even in 1.5, this api, getIntent(), is already listed as deprecated. The error message I get complains that getIntent() does not return a String, but setCurrentTab() expects a string. If I guess and change the line to read: "tabHost.setCurrentTab(1); // was setCurrentTab(getIntent())", then it compiles, builds, but does not run. I get the "stopped unexpectedly" error message from the emulator. I cannot even get Log.d to output, so it seems that it stops 'unexpectedly' very early. So the first and main question is: what is the correct fix to "tabHost.setCurrentTab(getIntent())" in the final line of OnCreate() in http://developer.android.com/resources/tutorials/views/hello-tabwidget.html? The second and simpler question is: did I guess right in replacing 'mTabHost' with tabHost in the one place where that occurs?

• Can the Windows Indexing Service restart an app pool if it doesn't index the Web.Config?

  - by JamesEggers

  I am having a slight debate with a colleague of mine on this subject. Scenario: A web site has a sub directory that is indexed using the Windows Indexing Service. There is not a web.config in this directory and the indexing service is not indexing the parent directory which is the site root. Something is causing the app pool to restart at supposedly random times. From what I am finding online, the only time the Windows Indexing service would cause an app pool restart is if it's indexing the web.config (or machine.config). My colleague is saying that the indexing service is causing the restarts just because it's in a child folder of the root. So...does anyone have any information or experience on this? If the indexing service is indexing a child folder of the root but not the root directory itself, can it cause IIS to restart the site's app pool? EDIT: The sub directory in question is NOT the bin directory. I know it would cause such as well; however, the bin directory is not the target of the indexing service.

• Android: Make application background behave like homescreen background

  - by Mannaz

  Hi, I have a big background image for my views's background, which also can be tiled (it's repeadable). When switching from one Activity to another i want the background to behave like on the homescreen (the background moves only a bit, but the foreground moves one screen with). Is this possible and how? Here is my current background definition: Manifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@style/MyAppStyle"> styles.xml: <style name="MyAppStyle" parent="@android:style/Theme.NoTitleBar"> <item name="android:windowBackground">@drawable/window_background_descriptor</item> window_background_descriptor.xml: <?xml version="1.0" encoding="utf-8"?> <bitmap xmlns:android="http://schemas.android.com/apk/res/android" android:src="@drawable/window_background" android:tileMode="repeat" />

• Entity Framework vs. nHibernate for Performance, Learning Curve overall features

  - by hadi

  I know this has been asked several times and I have read all the posts as well but they all are very old. And considering there have been advancements in versions and releases, I am hoping there might be fresh views. We are building a new application on ASP.NET MVC and need to finalize on an ORM tool. We have never used ORM before and have pretty much boiled down to two - nHibernate & Entity Framework. I really need some advice from someone who has used both these tools and can recommend based on experience. There are three points that I am focusing on to finalize - Performance Learning Curve Overall Capability Your advice will be highly appreciated. Best Regards,

• wpf usercontrol within usercontrol with the help of region manager

  - by Miral

  Sorry for weird title, actually i can only explain my question but cannot put in a few words in the title. I am developing WPF Composite application with PRISM approach. I have got a common WPF usercontrol which is gonna be used by all other usercontrol, i.e. usecontrol within a usercontrol. The common usercontrol has got a button "ProcessMultiple" which I want it to behave differently from all usercontrol. I am using RegionManager to add this views. I have got PresentationModel for all the usercontrol IRegion historyUpdaterRegion = _regionManager.Regions["HistoryUpdaterRegion"]; IRegionManager historyUpdaterRegionManager = historyUpdaterRegion.Add(_unityContainer.Resolve<IHistoryDocumentUpdaterPresentationModel>().View, null, true); historyUpdaterRegionManager.RegisterViewWithRegion("ProcessMultiple", () => _unityContainer.Resolve<IProcessMultiplePresentationModel>().View); IRegion refundArrivalRegion = _regionManager.Regions["RefundArrivalRegion"]; IRegionManager refundArrivalRegionManager = refundArrivalRegion.Add(_unityContainer.Resolve<IRefundArrivalProcessorPresentationModel>().View, null, true); refundArrivalRegionManager.RegisterViewWithRegion("ProcessMultiple", () => _unityContainer.Resolve<IProcessMultiplePresentationModel>().View);

• How to detect changes to Address Book after ABPersonViewController presentation

  - by nkhorman

  I have two view controllers that allow changes to the Address Book. The first one lets you add or create an entry based on an ABRedordRef or edit an existing ABRecordRef, by presentation of either ABUnknownPersonViewController or ABPersonViewController. The second one is a standard ABPeoplePickerNavigationController that allows you to view/edit any of the contents of the Address Book. Both views are accessible easily accessible to the use via the main application UITabBarController. How can I determine that changes were made by either view controller, so that I can force data dependency changes to a third separate view controller. I thought that I saw a notification center message that I could subscribe to, but I can't seem to find it again... I don't care if the notification center is the method that should be used, or a delegate protocol or... whatever, I don't care, I just need to know how to detect the change or the need to re-sync with the Address Book. Can someone Please point me in the right direction. Thank you.

• White view when launch iOS app in simulator

  - by user820511

  I have been working for 4 months on an app, its pretty complex and works fine. Now suddenly, I added a new class and did some changes to the MainWindow.xib with all my views there and now I just get a plain white view when I launch it with simulator. I even stripped it down completely to nothing but the appdelegate and one simple plain view with a button. So basically I've got an app with nothing but an appDelegate managing a tabBar, launching with one simple view, no frameworks no nothing and I still get a white app. There must be an option somewhere that I must have activated for the running of app in simulator but I can't figure it out. Thank you

• Crawler do not create custom crawled properties

  - by user173739

  These days i have faced with very strange problem. I have development environment with MOSS 2007 SP 2 and WS 2008, i have search configured and everything works great. I have started to configuring staging environment (MOSS 2007 SP2 with June CU) and create new farm and new SSP. I have deployed my changes with package (wsp) and manually create site collections, sub webs, pages and so on. When fill crawl finishes, i see in Crawl log that all my pages have been successfully crawled and when i use some test tools to query search, my pages have been found. In crawl log there is few errors like http://mysite/sites/de/pages "The crawler could not communicate with the server. Check that the server is available and that the firewall access is configured correctly..", but all pages in this Page library were indexed. The problem is that i use custom managed properties (mapped to custom crawled properties) in search queries, but crawler didn't create crawled properties for all my new site columns. For example for site column IsAccent the crawler didn't create cralwed property ows_isAccesnt. I'm sure that i have created pages for specific content type and all my crawl categories have checked "Automatically discover new properties when a crawl takes place ". In site settings - Searchable columns i haven't got any column selected as Nocrowl. I tried to export my managed and crawled properties from dev environment to stage evironment but all my managed properties were empty, after that i recreated SSP...the result was the same... I checked specific page with tools like Sharepoint Manager 2007 and U2U Caml Query Builder 2007 that content type is correct, and i can see values of my custom site collumns.... Using U2U Caml Query Builder 2007 agains some Page library in Result tab i can see ows_IsAccent (my site collumn is IsAccent) and others site columns, but i can't find them in Crawled properties. Any idias?

• How do I suppress eclipse warning: Referenced identifier 'VIEWNAME:secondaryid' in attribute 'id' ca

• UIScrollView won't autorotate

  - by clozach

  My app design requires the same scrolling functionality found in the iPhone's native Photos app when browsing photos in full screen. Specifically: Each view snaps into place as the view is swiped Scrolling happens in only one direction Rotating the iPhone rotates the entire scrolling region as well such that the frame of each subview (photos, in Apple's case) rotates in-place and paging is still in the same direction (left-to-right) I started to use Apple's sample PageControl code as a launching point, and everything was going swimmingly until I attempted adding autorotation to the code. My sense from the docs was that all I had to do to get autorotation working was to add this to the sample code's MyViewController.m - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } While that does seem to cause the subviews' backgrounds to rotate, the UILabels and the enclosing UIScrollView stay fixed so that, from a user perspective, paging through the views now requires up/down flicking instead of left/right.

• How to display and update data in MVC2

  - by Picflight

  Table Product Product Id Product Name Table ProductSupplier ProductSupplierId ProductId SupplierId Table Supplier SupplierId SupplierName I have the above 3 tables in my database, ProductSupplier is the lookup table. Each Product can have many suppliers. I am using Entity Framework. Using Web Forms it was fairly easy to display a Product on a web page and bind a repeater with the suppliers information. Also, with Web Forms it was easy to Add new Product and suppliers, the linkage seemed easy. How do you do this sort of functionality in MVC? In the Create View below, I want to be able to Add the Supplier as well. Is there a better approach that I might be missing here? This is how I did it with Web Forms. Beyond the code below I am totally lost. I can show data in a list and also display the Suppliers for each Product, but how do I Add and Edit. Should I break it into different views? With Web Forms I could do it all in one page. namespace MyProject.Mvc.Models { [MetadataType(typeof(ProductMetaData))] public partial class Product { public Product() { // Initialize Product this.CreateDate = System.DateTime.Now; } } public class ProductMetaData { [Required(ErrorMessage = "Product name is required")] [StringLength(50, ErrorMessage = "Product name must be under 50 characters")] public object ProductName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } public class ProductFormViewModel { public Product Product { get; private set; } public IEnumerable<ProductSupplier> ProductSupplier { get; private set; } public ProductFormViewModel() { Product = new Product(); } public ProductFormViewModel(Product product) { Product = product; ProductSupplier = product.ProductSupplier; } } } ProductRepository public Product GetProduct(int id) { var p = db.Product.FirstOrDefault(por => por.ProductId == id); p.ProductSupplier.Attach(p.ProductSupplier.CreateSourceQuery().Include("Product").ToList()); return p; } Product Create View <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MyProject.Mvc.Models.ProductFormViewModel>" %> <%= Html.ValidationSummary("Please correct the errors and try again.") %> <% using (Html.BeginForm()) {%> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.ProductId) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.ProductId) %> <%= Html.ValidationMessageFor(model => model.Product.ProductId) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.ProductName) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.ProductName) %> <%= Html.ValidationMessageFor(model => model.Product.ProductName) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.Description) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.Description) %> <%= Html.ValidationMessageFor(model => model.Product.Description) %> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %>

• Call named routes in CakePHP as the same way in Ruby on Rails

  - by Lucas Renan

  How can I call a route (in the view) in CakePHP as the same way in Rails? Ruby on Rails routes.rb map.my_route '/my-route', :controller => 'my_controller', :action => 'index' view link_to 'My Route Name', my_route_path CakePHP routes.php Router::connect('/my-route', array('controller' => 'my_controller', 'action' => 'index')); view $html->link('My Route Name', '/my-route'); But I think the Rails way is better, because I can make changes in the "url" and I don't need changes the code of the views.

• iphone: UIwebview curl effect

  - by eshalev

  Hello, I would like to make a standard view container which will give me the curl animation effect on multiple views. Something like uiscrollview and paging, only with a different animation(curl). I will be using UIwebviews as my separate pages. The problem: I do not know how to trap swipes in UIwebviews, But I see that UIscrollview implments this (swiping a uiwebview in a uiscrollview will bring me to the next view). I am therefore assuming that the implmentation of UIscrollview is trapping UIwebview swipes. How can i achieve the same functionality? I also need the UIWebview to keep functioning (as when embedding it in a uiscrollview)
