Cum sa controlam modul in care un serviciu windows porneste din cod

Prin intermediul la clasei ServiceController putem sa controlam un serviciu windows. Il putem in orice moment porni sau oprii. Dar daca avem nevoie sa ii schimbam startup type? De exemplu daca vreau sa ii schimb startup type-ul de pe manual pe automat?
Din pacate ServiceController nu ne oferă aceasta funcționalitate. Din cod C# nu am gasit o posibilitatea prin care as putea sa fac acest lucru. In schimb am gasit in registry bine ascunse aceste valori.
Daca deschidem registrii si ne uitam sub Local System in path-ul "SYSTEM\CurrentControlSet\Services\" o sa gasim lista cu toate serviciile pe care le avem instalate pe masina. Pentru fiecare serviciu avem:
  • nume
  • descriere
  • tipul
  • startup type-ul
  • path-ul spre serviciu
  • etc
Daca schimbam una din aceste valori, sistemul de operare o sa faca update automat la serviciu. O solutie la probleme noastra este sa facem o metoda care scrie valoarea in registri.
public enum StartupModeType
{
Boot = 0,
System = 1,
Automatic = 2,
Manual = 3,
Disabled = 4
}
Mai sus este lista cu starile pe care le poate avea serviciu. Iar mai jos avem cele doua metode care fac get si set la aceasta valoarea:
public StartupModeType GetStartupMode(string serviceName)
{
RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(""SYSTEM\\CurrentControlSet\\Services\\" + serviceName);
StartupModeType startupMode = (StartupModeType)registryKey.GetValue("Start");
registryKey.Close();
return startupMode;
}
public void SetStartupMode(string serviceName, StartupServiceMode startupServiceMode)
{
RegistryKey registryKey = Registry.LocalMachine.OpenSubKey("SYSTEM\\CurrentControlSet\\Services\\Start",RegistryKeyPermissionCheck.ReadWriteSubTree);
registryKey.SetValue(StartupTyeRegistryKey,(int)startupServiceMode);
registryKey.Close();
}
In functie de necesitati putem sa facem niste extension methods la ServiceController care sa se ocupe de acest lucru. O alta varianta era cream un proces nou si sa apelam "sc [numeServiciu] config".

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.

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.
