</application> </system.runtime.remoting> </configuration> generate, create none none on none projectsgenerate pdf-417 vb.net The config none for none uration file needs to be loaded in the client"s AppDomain using the RemotingConfiguration.Configure method. Once the configuration is loaded, the client can instantiate the remote objects using the new operator as illustrated in the following code:.

Microsoft .NET official Website // Project RemotingConfig/MyClientNew class MyApp { public static void Main() { RemotingConfiguration.Configure("MyClientNew.cfg"); // FOO Foo foo = new Foo(); String greeting = foo.

GetGreeting("Foo"); Console.WriteLine("Return value: {0}", greeting); // BAR Bar bar = new Bar(); greeting = bar.GetGreeting("Bar"); Console.

WriteLine("Return value: {0}", greeting); // BAZ Baz baz = new Baz(); greeting = baz.GetGreeting("Baz"); Console.WriteLine("Return value: {0}", greeting); } }.

Note that none none clients can also use Activator.CreateInstance or Activator.GetObject to override the configuration file settings for specified types.

Internally, RemotingConfiguration.Configure calls the method. RegisterWe llKnownClientType to associate a type with the URL of the remote server-activated object and. method Reg none for none isterActivatedClientType, to associate a type with the URL of the remote client-activated type. You can use these methods directly if you do not wish to use a client-side configuration file. This is illustrated in the following code:.

// Project RemotingConfig/MyClientUsingNew public static void Main() { // Configuring object information programmatically. // Foo - S none for none ingle-call object RemotingConfiguration.RegisterWellKnownClientType( typeof(Foo), "http://localhost:8085/GetFoo"); // Bar - Singleton object RemotingConfiguration.RegisterWellKnownClientType( typeof(Bar), "http://localhost:8085/GetBar"); // Baz - Client-activated object RemotingConfiguration.

RegisterActivatedClientType( typeof(Baz), "http://localhost:8085/"); // Now instantiating classes using "new" operator Foo foo = new Foo(); // Foo ...

}. As may be obvious, if a type is not associated with a remote URL, the new operator ends up creating a local object. Note that RegisterWellKnownClientType and RegisterActivatedClientType register well-known types only for the AppDomain they are invoked from. Each AppDomain that wishes to use the new operator for remote objects should call these methods (or load the configuration file).

. Hosting under ASP.NET Earlier, I mentioned that a reason to separate the main business logic (Greeting.dll in our case) from the hosting logic (MyHost.exe) is that it is possible to publish classes under ASP.

NET, thus eliminating the need for a hosting executable. Let"s see how this can be done. Under ASP.

NET, classes are published using a configuration file. The file is named web.config and the configuration format is similar to one we saw earlier for the server-side settings.

There are just a few differences: 1. 2. Under ASP.

NET, classes are always published using the HTTP channel. Therefore, channel information should not be present in web.config.

ASP.NET recognizes only two extensions for the URI, .rem or .

soap. These two extensions are defined in the global configuration file (Machine.config).

If need be, you can add your own extension by editing this file. 3. The <application> element should not have any name attribute.

When ASP.NET gets loaded for a specific Web application, it automatically sets the name of the application to the alias name of the IIS virtual directory in which it is being hosted..

Here is th none for none e modified version of our server-side configuration file that can be used under ASP.NET (Project. WebApplica tion): <configuration> <system.runtime.remoting> <application> <service> <wellknown type="MyCompany.

Foo, Greeting" mode="SingleCall" objectUri="GetFoo.rem" /> <wellknown type="MyCompany.Bar, Greeting" mode="Singleton" objectUri="GetBar.

rem" /> <activated type="MyCompany.Baz,Greeting" /> </service> </application> </system.runtime.

remoting> </configuration>. To avoid a none none ny naming conflicts, I have defined the remote types under the namespace MyCompany. Using the company name as a namespace is a good coding guideline. To host ASP.

NET, you need to have IIS Web server running on your machine. Here are the steps needed to host our assembly under ASP.NET: 1.

Create a new virtual directory under IIS. Give a suitable name for the alias and point the virtual directory (also called the virtual root or vroot) to the directory where web.config resides.

This is an important step. ASP.NET expects web.

config to be present in the vroot (although it is possible to customize the behavior for a subdirectory under vroot by defining another web.config in the subdirectory). For our experiment, let the alias name be Greeting and the directory be.
