C++: Connect to the Server
To connect to the VistA M Server from your C++ program:
1. Set the server and port to connect to:
// Set the Server and Port properties to determine where to connect.
RPCInst.RPCBPropSet("Server", server);
RPCInst.RPCBPropSet("ListenerPort", "9200");
2. Set the Connected property to true; this attempts a connection to the VistA M Server:
// Set the Connected property to True, to connect.
RPCInst.RPCBPropSet("Connected", "1");
3. Check if you are still connected. If so, you can continue (your connection was made). If not, you should quit or branch accordingly:
// If still connected, can continue.
RPCInst.RPCBPropGet("Connected", Value);
if (atoi(Value) != 1) return false;
4. Attempt to create context for your application's "B"-type option. If you can't create context, you should quit or branch accordingly. If RPCBCreateContext returns True, then you are ready to call all RPCs registered to your application's "B"-type option:
// Create Context for your application's option (in this case, XWB EGCHO).
result = RPCInst.RPCBCreateContext("XWB EGCHO");
return result;
