.NET APIs for Distributed Mode

In your .NET source code, include the necessary code to run your report application.

Provide the remote connection details

In the .cs source code, include the following:
RemoteConnection remoteConnection = new RemoteConnection(report);  
remoteConnection.host = "GRE_server_name";   
remoteConnection.port = "port";
  • GRE_server_name is the name of the server where the GRE is running.
  • port is the port number where the GRE is listening.

Simple code sample

The code sample below updates the simple .NET example to include the remote connection details for a GRE on a server named "huascar", listening on port 1974.
