• Entity Framework + SQLite deployment

  - by Pompair

  Hi, I have a ASP.NET MVC app that is using SQLite database through Entity Framework. Everything works on VS 2008's local development webserver. However, deploying the web app to my service provider causes this error: [ArgumentException: Unable to find the requested .Net Framework Data Provider. It may not be installed.] System.Data.Common.DbProviderFactories.GetFactory(String providerInvariantName) +1308959 System.Data.EntityClient.EntityConnection.GetFactory(String providerString) +35 Service provider has commented that they do not support SQLite. I had though that SQLite is independent of service provider's settings since it's App_Data deployable. Has anyone experiences of a succesfull Entity Framework + SQLite deployment? Cheers, -pom-

• Any competitors to db4o on compact framework?

  - by MrJeepster

  We've been trying db4o for persisting objects on the compact framework. It works very well from our tests so far. However, it appears they are on the expensive side for small startups with minimal units needed. Does anyone know of any similar object databases for the compact framework? How about a open source one that is free for commercial use? :) Thank you. EDIT: We're really looking for an object database. We don't want to create our own persistence framework at this point and would prefer being able to just save/retrieve the actual object trees.

• LINQ to SQL vs Entity Framework for an app with a future SQL Azure version

  - by Craig L

  I've got a vertical market Dot Net Framework 1.1 C#/WinForms/SQL Server 2000 application. Currently it uses ADO.Net and Microsoft's SQLHelper for CRUD operations. I've successfully converted it to Dot Net Framework 4 C#/WinForms/ SQL Server 2008. What I'd like to do is also offer my customers the ability to use SQL Azure as a backend storage for their data instead of local/LAN SQL Server. If I know SQL Azure is in my application's future, should I: A. Switch to LINQ to SQL B. Swith to Entity Framework C. Stick with ADO.Net and SQLHelper Thanks !

• Building a python module and linking it against a MacOSX framework

  - by madflo

  I'm trying to build a Python extension on MacOSX 10.6 and to link it against several frameworks (i386 only). I made a setup.py file, using distutils and the Extension object. I order to link against my frameworks, my LDFLAGS env var should look like : LDFLAGS = -lc -arch i386 -framework fwk1 -framework fwk2 As I did not find any 'framework' keyword in the Extension module documentation, I used the extra_link_args keyword instead. Extension('test', define_macros = [('MAJOR_VERSION', '1'), ,('MINOR_VERSION', '0')], include_dirs = ['/usr/local/include', 'include/', 'include/vitale'], extra_link_args = ['-arch i386', '-framework fwk1', '-framework fwk2'], sources = "testmodule.cpp", language = 'c++' ) Everything is compiling and linking fine. If I remove the -framework line from the extra_link_args, my linker fails, as expected. Here is the last two lines produced by a python setup.py build : /usr/bin/g++-4.2 -arch x86_64 -arch i386 -isysroot / -L/opt/local/lib -arch x86_64 -arch i386 -bundle -undefined dynamic_lookup build/temp.macosx-10.6-intel-2.6/testmodule.o -o build/lib.macosx-10.6-intel-2.6/test.so -arch i386 -framework sgdosx -framework srtosx -framework ssvosx -framework stsosx Unfortunately, the .so that I just produced is unable to find several symbols provided by this framework. I tried to check the linked framework with otool. None of them is appearing. $ otool -L test.so test.so: /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1) There is the output of otool run on a test binary, made with g++ and ldd using the LDFLAGS described at the top of my post. On this example, the -framework did work. $ otool -L vitaosx vitaosx: /Library/Frameworks/sgdosx.framework/Versions/A/sgdosx (compatibility version 1.0.0, current version 1.0.0) /Library/Frameworks/ssvosx.framework/Versions/A/ssvosx (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1) May this issue be linked to the "-undefined dynamic_lookup" flag on the linking step ? I'm a little bit confused by the few lines of documentation that I'm finding on Google. Cheers,

• Recommend a PHP framework for new PHP programmer

  - by webworm

  Hi All, I am fairly new to PHP but not programming in general. I was hoping I could get some suggestions on the best type of PHP framework to start with considering my basic experience with PHP. I have a .NET and ASP.NET background and I am familiar with the MVC design pattern. I would prefer to start with a framework that makes logical design easier but does not generate all the code for you. I have read some like the Zend framework for this. Opinions?

• What kinds of job scheduler framework or solution do you recomend on window server system

  - by Samuel.P

  Hi Guys My Company is running a lots of batch jobs to process data for partners. We used to use sql server agent to execute batch process. I found it's very difficult to get batch process information like log or status when i working on sql server's agent. So I'd like to change my company's job scheduling process to another stable solution But I dind't know which solutions to choose. I tried to find as same solution as CA Autosys. My Company use window server system. We shoud consider framework or solution should be configured using solution's api because i plan to make a asp.net web application to manage our job shceduler. What kinds of job scheduler Framework or inexpensive solution do you suggest? Regards, Park PS: I think Quartz Framework has a good reputation on J2EE system. But I am not sure Quartz.NET is as good as orginal java version.

• Entity Framework vs LINQ to SQL

  - by Chris Roberts

  Now that .NET v3.5 SP1 has been released (along with VS2008 SP1), we now have access to the .NET entity framework. My question is this. When trying to decide between using the Entity Framework and LINQ to SQL as an ORM, what's the difference? The way I understand it, the Entity Framework (when used with LINQ to Entities) is a 'big brother' to LINQ to SQL? If this is the case - what advantages does it have? What can it do that LINQ to SQL can't do on its own?

• How to assign default values and define unique keys in Entity Framework 4 Designer

  - by csharpnoob

  Hello, I've had a look at the Entity Framework 4. While generating code for the SQL Server 2008 I came to the point where I want to define some default values for some fields. how to define in the designer for a Created DateTime Field the DateTime.Now default value? - Error 54: Default value (DateTime.Now) is not valid for DateTime. The value must be in the form 'yyyy-MM-dd HH:mm:ss.fffZ' how to make for code generation a string Field unique. Like E-Mail or Username can exists only once in the table. I've search alot in the internet and also checked my books Pro Entity Framework 4.0 and Programming Entity Framework. But none of them seems to come up with the default value issue, or using sql commands as default values for database generation. Another thing is, how to prevent on database generation always from droping tables? Instead i want to append non existing fields and keep the data. Thanks for any suggestions.

• Editing and iPhone SDK Framework ?

  - by Chris

  I am working with MapKit and want to be able to add a (NSString *)itemTag value to each of my annotations. I have created myAnnotiation.m and myAnnotation.h I tried adding itemTag to the myAnnotation.h/m but when I try to access currentAnnotation.itemTag within my main code, it says "itemID not found in protocols" - so I went to the MapKit.Framework and into MKAnnotation.h. I added (NSString *)itemID, but when I save the .h file in the Framework, it changes the file's icon and doesn't appear to by jiving with everything else. Any help or links to help would be greatly appreciated. I am not even sure if I'm on the right path here, but Googling "modify iphone sdk framework" does not turn up much.

• Entity Framework: Data Centric vs. Object Centric

  - by Eric J.

  I'm having a look at Entity Framework and everything I'm reading takes a data centric approach to explaining EF. By that I mean that the fundamental relationships of the system are first defined in the database and objects are generated that reflect those relationships. Examples Quickstart (Entity Framework) Using Entity Framework entities as business objects? The EF documentation implies that it's not necessary to start from the database layer, e.g. Developers can work with a consistent application object model that can be mapped to various storage schemas When designing a new system (simplified version), I tend to first create a class model, then generate business objects from the model, code business layer stuff that can't be generated, and then worry about persistence (or rather work with a DBA and let him worry about the most efficient persistence strategy). That object centric approach is well supported by ORM technologies such as (n)Hibernate. Is there a reasonable path to an object centric approach with EF? Will I be swimming upstream going that route? Any good starting points?

• Simple File-based Record Storage with Fast Text Searching for Compact Framework and Silverlight

  - by Eric Farr

  I have a single table with lots of records ( 100k) that I need to be able to index and search on several text fields. The easiest searches will have the first part of the string specified (eg, LIKE 'ABC%' in SQL). The tougher searches will need to search for any substring within the text fields (eg, LIKE '%ABC%' in SQL). I need to run on the Compact Framework. SQL Compact is a memory hog and overkill for my one table. Besides, I'd like to be able to run on Silverlight 4 eventually. The file and indexes can be generated on the full .NET Framework and I only need read capability on the Compact Framework. My records are not especially large and can be expressed in fix length format. I'm looking for some existing code or libraries to avoid having to write a file-based BTree implementation from scratch.

• Protocol buffer deserialization and a dynamically loaded DLL in Compact Framework

  - by cloudraven

  I saw a question related to this on the full framework here. Since it seems to have stayed unresolved for quite a while and this is for the compact framework, I though it would be better to create a new question for it. I want to deserialize types for which I am loading assemblies dynamically (with Assembly.LoadFrom) and I am getting a "Unable to identify known-type for ProtoIncludeAttribute" error. In the related question I mentioned, it was hinted that hooking AppDomain.AssemblyResolve event would help solving the problem. It makes sense for the full framework, but that event is not available in the CF. I wonder if there is a way to do this with CF. The structures I am using look a lot like this and all the classes required for deserialization are loaded from the same Assembly. If the assembly is referenced instead of dynamically loaded it works fine, but fails if done dynamically.

• how to integrate Zend Framework MVC with existing site

  - by Joel

  Hi guys, So I'm slowly tackling OO and Zend Framework and their MVC process in particular. I have an existing website and web-based calendar application that was designed by me, but coded by a different person and done procedurally. I understand that it will be very difficult for my application to ever be completely OO without a full re-write, and I'm fine with that. I have a lot of updates and modifications I want to do in the future, so I'm wanting to start replacing some of the basic components (login, authentication. etc) now, and continue to learn as I go. Again, I'm really a newbie at programming and OO. What I'm wondering is if I'm wanting to incorporate the Framework, then would I just first drop my whole site into the /public folder of the Framework and then start pulling functionality out from there?

• .NET platform independant sync framework

  - by Quandary

  Question: I need to synchronize a few ActionScript files from my computer to a network share (backup). I saw a quick fix would be using Microsoft Sync Framework for this, and write a windows service. My problem is I also use Linux, and before I start with MS vendor lockin, is there any sync framework/library/whatever I could use that works accross platform? Or does the MS sync framework work on Linux, too? It is my understanding that it is a wrapper around some com objects, thus it wouldn't work. All I need is synchronizing files. So never mind the database part, although it would be nice to have it, too.

• Play 2.0 javaToDo tutorial doesn't compile

  - by chsn

  I'm trying to follow the Play2.0 JavaToDO tutorial and for some reason it just doesn't want to work. Have looked through stackoverflow and other online resources, but haven't find an answer to this and it's driving me crazy. Attached code of the Application.java package controllers; import models.Task; import play.data.Form; import play.mvc.Controller; import play.mvc.Result; public class Application extends Controller { static Form<Task> taskForm = form(Task.class); public static Result index() { return redirect(routes.Application.tasks()); } public static Result tasks() { return ok( views.html.index.render(Task.all(), taskForm)); } public static Result newTask() { return TODO; } public static Result deleteTask(Long id) { return TODO; } } Attached code of the Task java package models; import java.util.List; import javax.persistence.Entity; import play.data.Form; import play.data.validation.Constraints.Required; import play.db.ebean.Model.Finder; import play.mvc.Result; import controllers.routes; @Entity public class Task { public Long id; @Required public String label; // search public static Finder<Long,Task> find = new Finder( Long.class, Task.class); // display tasks public static List<Task> all() { return find.all(); } // create task public static void create(Task task) { task.create(task); } // delete task public static void delete(Long id) { find.ref(id).delete(id); // find.ref(id).delete(); } // create new task public static Result newTask() { Form<Task> filledForm = taskForm.bindFromRequest(); if(filledForm.hasErrors()) { return badRequest( views.html.index.render(Task.all(), filledForm) ); } else { Task.create(filledForm.get()); return redirect(routes.Application.tasks()); } } } I get a compile error on Task.java on the line static Form<Task> taskForm = form(Task.class); As I'm working on eclipse (the project is eclipsified before import), it's telling me that taskForm cannot be resolved and it also underlines every play 2 command e.g. "render(), redirect(), bindFromRequest()" asking me to create a method for it. Any ideas how to solve the compilations error and also how to get Eclipse to recognize the play2 commands? EDIT: updated Application.java package controllers; import models.Task; import play.data.Form; import play.mvc.Controller; import play.mvc.Result; public class Application extends Controller { // create new task public static Result newTask() { Form<Task> filledForm = form(Task.class).bindFromRequest(); if(filledForm.hasErrors()) { return badRequest( views.html.index.render(Task.all(), filledForm) ); } else { Task.newTask(filledForm.get()); return redirect(routes.Application.tasks()); } } public static Result index() { return redirect(routes.Application.tasks()); } public static Result tasks() { return ok( views.html.index.render(Task.all(), taskForm)); } public static Result deleteTask(Long id) { return TODO; } } Updated task.java package models; import java.util.List; import javax.persistence.Entity; import play.data.Form; import play.data.validation.Constraints.Required; import play.db.ebean.Model; import play.db.ebean.Model.Finder; import play.mvc.Result; import controllers.routes; @Entity public class Task extends Model { public Long id; @Required public String label; // Define a taskForm static Form<Task> taskForm = form(Task.class); // search public static Finder<Long,Task> find = new Finder( Long.class, Task.class); // display tasks public static List<Task> all() { return find.all(); } // create new task public static Result newTask(Task newTask) { save(task); } // delete task public static void delete(Long id) { find.ref(id).delete(id); // find.ref(id).delete(); } }

• Using a framework in a PreferencePane

  - by Jonathan

  Hi, i am currently trying to implement a "third party framework" (FeedbackReporter.Framework) into my preferencepane. Unfortunately I am getting the following error all the time when trying to launch my preference pane: 16.05.10 23:13:30 System Preferences[32645] dlopen_preflight failed with dlopen_preflight(/Users/me/Library/PreferencePanes/myPane.prefPane/Contents/MacOS/myPane): Library not loaded: @executable_path/../Frameworks/FeedbackReporter.framework/Versions/A/FeedbackReporter Referenced from: /Users/me/Library/PreferencePanes/myPane.prefPane/Contents/MacOS/myPane Reason: image not found for /Users/me/Library/PreferencePanes/myPane.prefPane As far as I read so far, this problem is probably caused because my prefPane is no actual app, but a "plugin" of "System Settings.app" and thus @executable_path resolves to a path within the bundle of this app, instead of the bundle of my prefpane. But I don't really picked up howto fix this problem. I guess it must be fairly easy since it should be a usual case that people use non-apple-frameworks in PreferencePanes. Thanks for your hints!

• Routing not working correctly using the laravel framework

  - by samayres1992

  I'm using the book wrote by one of the guys that created laravel, so I'd like to think for the most part this code isn't horribly wrong. My server is setup with nginx serving all static files and apache2 serving php. My config for each are the following: apache2: <VirtualHost *> # Host that will serve this project. ServerName litl.it # The location of our projects public directory. DocumentRoot /var/www/litl.it/laravel/public # Useful logs for debug. CustomLog /var/log/apache.access.log common ErrorLog /var/log/apache.error.log # Rewrites for pretty URLs, better not to rely on .htaccess. <Directory /var/www/litl.it/laravel/public> <IfModule mod_rewrite.c> Options -MultiViews RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L] </IfModule> </Directory> nginx: server { # Port that the web server will listen on. listen 80; # Host that will serve this project. server_name litl.it *.litl.it; # Useful logs for debug. access_log /var/log/nginx.access.log; error_log /var/log/nginx.error.log; rewrite_log on; # The location of our projects public directory. root /var/www/litl.it/laravel/public; # Point index to the Laravel front controller. index index.php; location / { # URLs to attempt, including pretty ones. try_files $uri $uri/ /index.php?$query_string; } # Remove trailing slash to please routing system. if (!-d $request_filename) { rewrite ^/(.+)/$ /$1 permanent; } # PHP FPM configuration. location ~* \.php$ { proxy_pass http://127.0.0.1:8080; include /etc/nginx/proxy_params; try_files index index.php $uri =404; include /etc/nginx/fastcgi_params; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root/php/$fastcgi_script_name; } # We don't need .ht files with nginx. location ~ /\.ht { deny all; } location @proxy { proxy_pass http://127.0.0.1:8080; include /etc/nginx/proxy_params; } error_page 403 /error/403.html; error_page 404 /error/404.html; error_page 405 /error/405.html; error_page 500 501 502 503 504 /error/5xx.html; location ^~ /error/ { internal; root /var/www/litl.it/lavarel/public/error; } } I'm including these server configs, as I feel this maybe the issue? Here is my incredibly basic routing file that should return "routing is working" on domain.com/test but instead it just returns the homepage. <?php Route::get('/', function() { return View::make('hello'); }); Route::get('/test', function() { return "routing is working"; }); Any ideas where I'm going wrong, I'm following this tutorial very closely and I'm confused why there is issue. Thanks!

• Attempting to install .NET framework 4 *full* installs *client* instead

  - by msorens

  On a Win7 SP1 32-bit machine, I initially had .NET 4 client installed and wanted to upgrade to .NET 4 full. I downloaded the full installer dotNetFx40_Full_x86_x64.exe from Microsoft. After download the file showed 48.11MB, the correct size for the full package (vs. 41MB for the client). I ran the installer and it first prompted to repair or remove the existing package. I chose to remove, so uninstalled the two parts, 4 extended and 4 client. Reboot. I reran the installer and it began installation, showing that it was installing the client. Though this raised an eyebrow for me, I let it run to completion, thinking it might be reporting the full install in sections. But after completion, I again ended up with 4 extended and 4 client installed! Obviously I am missing something; ideas...?

• Is it possible to automate a driver change on Windows for a plug&play peripheral ?

  - by Gnoupi

  Is it possible to automate a change of driver for a same peripheral, under Windows ? Typically to switch between two ones. (I'm talking about the kind of driver which doesn't require the computer to reboot, typically). I have a peripheral for which I use the constructor's driver in some cases, but also a modified driver in other cases. Not that the changing driver is really annoying, but I would like to know if it would be possible to make it easier, like for example in a shortcut. I know the name of the driver, even which files involved. For more details, the concerned peripheral is a "Xbox360 Gamepad for Windows" (or something like this). The base driver is good for new games, but it doesn't handle correctly older ones (some issues with axes, and vibrations). The modified driver makes it behave like a classic controller, but then it doesn't work correctly on new games (typically using the new version of dxinput linked to the "Games for Windows"). However, this is not a question specific to this gamepad, I'm asking in general about automating this change of drivers. I currently use Windows XP, so my question is mostly about it, but I'm also interested in the same issue for later versions (Windows 7, most likely). I'm not really sure if this is even possible, but in case someone has an idea, I'm asking.
