SQL Server : Unable to open the physical file “”. Operating system error 32.

How to solve the error: SQL Server : Unable to open the physical file “”. Operating system error 32.

Hi all, today I faced a big problem with SQL server, I couldn’t attach the database file to my project, I followed these steps to add my database:

1- add new connexion

2- browse to my database file in C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\MyDB

3- gone to advanced settings and changed the data source from SQLEXPRESS to “.” and user instance to false.
so when I clicked on OK I had the following error:  Unable to open the physical file “”. Operating system error 32.

What I did to solve this is to open SQL Server management studio 2008 R2 –> connect to my server –> right click on my database name –>tasks –> take offline.

I returned to visual studio 2010 and reattached the database, everything worked properly 🙂

Hope that helps.

LINQ to Entities does not recognize the method Last()

Solve the error LINQ to Entities does not recognize the method Last().

Hi all, in this post I will show you how to resolve a little problem when using ADO.net entity framework

Details of the problem: when trying to use the method last() to have the last record in the database table using thi code :

databaseEntities db = new databaseEntities();
UserSet user = new UserSet();
user = (from e1 in db.UserSet select e1).Last();

it throws an exception that says :

LINQ to Entities does not recognize the method ‘Myapp.UserSet Last[UserSet](System.Linq.IQueryable`1[Myapp.UserSet])’ method, and this method cannot be translated into a store expression.

Solution:

replace the instruction : user = (from e1 in db.UserSet select e1).Last();  with user = (from e1 in db.UserSet select e1).ToList().Last();  and it will work properly

ASP.NET : HTTP Error 404.3 – Not Found

How to solve the error ASP.NET : HTTP Error 404.3 – Not Found

I’m starting the first post by giving a solution to an issue that I faced when installing Visual Studio and IIS 7 in my new laptop, and trying to run my ASP.net web application.

Error Details :  HTTP Error 404.3 – Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.
This error happens when you install IIS after Visual studio, so you have to configure ASP.net with IIS.

Solution: to solve this issue, you may use Aspnet_regiis.exe (ASP.net IIS registration tool, more info here), to do this, follow these steps:

1. find  the path where aspnet_regiis.exe is situated, it should be situdated here :
   C:\Windows\Microsoft.NET\Framework\v4.0.30319
2. run cmd as an administrator and  run aspnet_regiis.exe by typing this command line :
   C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis -i
   (the option -i installs the current version of ASP.NET and configure IIS to use it)
3. Run your web application again, that should work properly

Hope that was helpful.
