How do I connect to a Server?

Connecting to your Server is the first thing that must be done before you can use any other SDK functionality.

In this example we:

• Create the Server object
• Create the ServerAddresses object
• Call Connect() on the Server object
• Check the value returned by the call to Connect() to ensure that we have successfully connected
• Display an appropriate error message if the Connect() call failed
• Disconnect from the Server object

For complete examples refer to the sample applications that come with the DecoderSDK.

Example

• C++
• C#
• Android

// Create the server object
server = new Server(L"Windows-General-Sample-App", L"os:Windows 7 x64, app:Windows General Sample App, app_ver:0.1.0");

// NOTE: 9300 is the default port for EdgeVis Server
ServerAddresses knownServer(L"my.server.com", 9300, false);
ServerAddresses availableServers;

//Connect to the server
OpResult result = server->Connect(knownServer,L"username",L"password", L"", availableServers, ConnectionStrategy::DEFAULT);

if(result == OR_Success)
{
  wcout << L"Connected to server!" << endl;

  // register to receive IServerListener callbacks
  server->RegisterListener(this);

} else {
  //The connection failed Check the reult for error message
  wcout << L"Connection failed!" << endl;
}

server->Disconnect();
