Operatii CRUD pe tables in Windows Azure

Se da obiectul de tip Point, cu doua propietati de tip int X si Y si un id tot de tip int, unde point implementeaza TableServiceEntity.

Initalizare:
//Initializare cont (se poate incarca din fisierul de configurare).
StorageAccountInfo account = ...
TableStorage tableStorage = TableStorage.Create(account);
//Creare tabel cu un anumit nume.
tableStorage.TryCreateTable("Point");
Salvare:
Point point = new Point();
...
TableStorageDataServiceContext context = table.GetDataServiceContext();
context.AddObject(point);
//Doar pe save se salveaza in tabel obiectul nostru.
context.Save();
Interogare:
TableStorageDataServiceContext context = table.GetDataServiceContext();
//Trebuie specificat numele tabelului. Un tabel poate sa contina orice tip de obiecte, chiar si de tipuri diferite.
var query = context .CreateQuery("Point").Where(item => item.Id == 10);
IEnumerable resultList = new TableStorageDataServiceQuery((DataServiceQuery)query).ExecuteAll();
Stergere:
//Dupa ce prin avem obiectul de tip Point( ajunge sa fie un obiect de tip Point care sa aibe partition key si row key corespunzator.
TableStorageDataServiceContext context = table.GetDataServiceContext();
context.DeleteObject(point);
context.SaveChanges()

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

Today blog post will be started with the following error when running DB tests on the CI machine:
threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration:

How to check in AngularJS if a service was register or not

There are cases when you need to check in a service or a controller was register in AngularJS.
For example a valid use case is when you have the same implementation running on multiple application. In this case, you may want to intercept the HTTP provider and add a custom step there. This step don’t needs to run on all the application, only in the one where the service exist and register.
A solution for this case would be to have a flag in the configuration that specify this. In the core you would have an IF that would check the value of this flag.
Another solution is to check if a specific service was register in AngularJS or not. If the service was register that you would execute your own logic.
To check if a service was register or not in AngularJS container you need to call the ‘has’ method of ‘inhector’. It will return TRUE if the service was register.
if ($injector.has('httpInterceptorService')) { $httpProvider.interceptors.push('httpInterceptorService&#…

Fundamental Books of a Software Engineer (version 2018)

More then six years ago I wrote a blog post about fundamental books that any software engineer (developer) should read. Now it is an excellent time to update this list with new entries.

There are 5 different categories of books, that represent the recommended path. For example, you start with Coding books, after that, you read books about Programming, Design and so on.
There are some books about C++ that I recommend not because you shall know C++, only because the concepts that you can learn from it.
