Hello everybody , I would like someone to help me in a question: I need to create a service that runs in the background on my application. From time to time it needs to perform a task. Can anyone tell me, nowadays, what the best way to do this? I 've seen some old tutorials (3 or 4 years) talking about BackgroundWorker , and others talking about Thread, Is there a more efficient way in the .NET 4.5.2 or these two ways are the only ones ?

Olá pessoal, gostaria que alguém me ajudasse em uma questão: Preciso criar um serviço que execute em background na minha aplicação. De tempos em tempos ele precisa executar uma determinada tarefa. O que eu gostaria de saber é qual a melhor forma de se fazer isso nos dias atuais ? Eu já vi alguns tutoriais meio antigos (3 a 4 anos) falando sobre BackgroundWorker, e outros falando sobre Thread, Existe alguma forma mais eficiente no .NET 4.5.2 ou esses dois caminhos são os únicos ?

Hi Guys,
I´m relatively new with c# and .net (about 1 year).
I want no create a windows (wpf) application using a remote database (Amazon RDS). In the future, I want no make another android application to use the same database.
My question is how to create this kind of application. (webservices, rest, or another solution) and if possible, links to tutorials talking about this kind of application.

Any help will be appreciated.

Hi Guys,

Is possible to use Tpararell.for or another multithreading method with TList objects ?

I want to do someone like this:

class PersonList: Tlist<TPerson>
class PersonPhoneList: Tlist<TPersonPhone>
...
var p: tperson;
begin
for p in PersonList do
begin
AssignPhones(p);
end;
end;

procedure AssigPhones(P: TPerson);
var f: tPersonPhone;
begin
for f in PersonPhoneList do
begin
if (f.PersonID = p.PersonID) then
p.Phones.add(f);

end;
end;

I have about 30.000 Person and 200.000 Phones, the time to process this operation is about 20 seconds.
I want to know if there is a way to do the work using multithreading or another method to reduce this time.

Hi Guys,
Maybe, someone can help me with some tips.
Im new to C#. Im migrating from Delphi and I have a question about Client/Server C# Technologies. I want to build an application using a SERVER located on a CLOUD machine. Only this Server must have access to database. CLIENT applications will comunicate only with SERVER. My question is: What are the best ways to do this job? TCP, WINSOCK, REST or another aproach ? There is a way to run SQL commands from CLIENT, but using the SERVER database connection ?

I'm disappointed with Embarcadero, because of your market strategy. New releases 2 times in the year. Of course, for EMB and the 3th Party Components Developers, is a great strategy, because the customers must buy updates ofen. But for the developers as me, this strategy is very expensive. The major problem is that embarcadero is focused to create new features to justify the cost of the new product version. But the new features, most time, is uncompleted and with many bugs. On the other hand, the focus to solve old problems, bugs, improve existing frameworks is in low priority.   And the new releases are 95% to solve problems from the previous version released features and 5% with new features. And there are 1 or 2 updates only for each release. After this, you must buy a new version of product to continue receiving updates for that uncompleted feature. With this strategy, at the moment, EMB is receiving a good $, but every day, more and more developers, as me, are thinking in change to another platform. In the few years, EMB will survive only from developers that must maintain your old applications developed with Delphi or C++. All new projects will be elaborared based on factors like robust, bug free and respect to the users.
Regards from a 15 years, Delphi Developer, with a broken heart with the way that EMB is making for my Delphi.
