DateTime.ToString() formats

Zilele astea m-am trezit cu niste probleme la o aplicatie la care am lucrat impreuna cu niste colegi. Formatul la ora nu era consistent in toata aplicatia. In unele locatii aparea sub forma 04:50, iar in alte locatii aparea sub forma 16:50.
Problema principala a fost ca s-a folosit formatarea fara a se cunoaste exact ce se afiseaza cand se foloseste HH sau hh.
Mai jos as vrea sa ne uitam la metoda ToString a unui DateTime. Aceasta primeste ca si parametru un string prin intermediul caruia se poate specifica modul de formatare a datei.
  • yyyy - o sa afiseze anul in formatul 2012
  • MMMM - luna in litere( iulie, august, ...)
  • MM - luna in cifre( 07, 08)
  • dddd - ziua din saptamana in litere( luni, marti)
  • ddd - ziua in litere dar prescurta
  • dd - ziua curenta din luna( 20, 31, ...)
  • H - ora in format 24, iar daca ora e mai mica ca 10 se va afisa o singura cifra, fara 0( 1, 2, 14)
  • HH - ora in format 24, iar daca ora e mai mica ca 10 se va afisa un 0 la inceput( 01, 02, 14)
  • h - ora in format AM/PM, iar daca ora e mai mica ca 10 se va afisa o singura cifra, fara 0( 1, 2, 2)
  • hh- ora in format AM/PM, iar daca ora e mai mica ca 10 se va afisa un 0 la inceput( 01, 02, 02)
  • tt - daca este AM sau PM( AM, PM)
  • mm - minute
  • ss - secunde


  1. No hai... asta e si in MSDN.

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 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.
