How do I choose between WCF, REST, POX and RIA services for a new Silverlight application -

-

A silverlight application can add it to a lot in different ways' server <

  • (or it is still left?)
  • Pox - Plain old XML (e.g., original XML)

    • For each of these, please say what is for this and when you will not use it or not, I have a very large description of "rules of thumb" for selection between them. not I see In.

    (The problem is that when designing your first Silverlight app, you should know that it is time to know all those who do not.)

    My two Euro Euro:

    WCF The service can be seen as a business layer, when your service is "intelligent" like "CalculateDiscountForClient" .

    ADO. Net Data Services (In fact, only a permanent implementation) is appropriate when your application is basically data-centric and the service is only a front-end for the database. That is, all of your service methods are GetCustomers, CreateInvoice, etc.

    RIA Services is a very new technology I have not used yet, but it seems that the application is useful in making applications, including the Silverlight part and service too tightly. Together: You define your service classes and methods in the service project, and they are automatically replicated in the Silverlight project in design time. In addition, you can define both WCF-style "action" methods and ADO.NET data service-style "data" methods. Use Pox if the future of the client part is changed from the client's future to any other technology (for example HTML + AJAX), then use it. Most interoperable options

    Regarding the differences of WPF, only I can think that for data access, whenever possible I will directly use ADOnate Data Connection (properly embedded in Data Access Layer, LINQ From SQL or like) instead of ADO.NET data services, because it is a more flexible way I have to say anyway that I have never developed anything in WPF.

    asp.net - Javascript/DOM Why is does my form not support submit()? -

    -
    This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

    sockets - Delphi: TTcpServer, connection reset when reading -

    -
    I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

    javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

    -
    I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
