Call Remote and Enterprise Server

In magic you had the option to use an Enterprise server that allowed you to run code on the server.

To do that you had to configure a server, run a broker on it and run magic engined to service requests that the server received. Let's call it the Application Server

To call that server, you would have used CallRemote or mgrqcmdl.exe

In .NET the application server is IIS. IIS replaces the Broker and the engines that you would have run on the server.

In the migration, such application will also have a project called .Server for example Northwind.server.

In that project you would find a file called Services.aspx that manages all of this.

That project is then mapped to a virtual directory on the IIS. See the IIS configuration article

Once you navigate to the Services.aspx URL on the web browser you'll get a small monitor application that allows you to follow up on the server information.

Calling the Server from an Application

For every Service that was defined in the migrated application you'll find a class in `...Shared.Remoting'

File3

Here's it's code: File2

As you can see - this class goes to the UserSettings class to get the Server's URL based on the Service name from the ini file.

If you'll look into the code of GetApplicationServerUrl you'll see that there are two ways to configure the server URL.

  1. For simple cases where there is only one server, you can add an entry in the ini called TemporaryRemoteUrl with the URL of the services.aspx file.

File4 2. For more complex cases where you have multiple services, you can add a section in the ini called ApplicationServers and add entries based on the Service Name set in the cs file under the Remoting namespace. File5

Performing the Actual Call from the code

Calling the service is simply done by Creating a new instance of the Service class and calling it's run method:

new Shared.Remoting.DefaultService().Run("PrintService", "SomeArgument", "Another Argument"); 

The first argument is the PublicName of the controller as defined in the ApplicationPrograms class. The other arguments are simply sent to that controller. For more call variations see Call Remote article

Calling a Remote Controller using a command line

You can also call a remote controller using a command line, the CMDL.exe file. See Running cmdl.exe article

Calling a remote Controller using Http

You can also call a remote controlling using simple HTTP - which is very useful for some scenarios. The syntax is similar to calling a web request.

http://localhost/Northwind.Server/services.aspx?prgname=PrintOrders&Arguments=someargument,anotherargument
