Hi,
I downloaded the project code (CommandPattern.zip) associated with this article describing a "server/client" model using RTI --- The Command Pattern: Distributed RPC with QoS; since the project was somewhat "old", I needed to rerun "rtiddsgen" and feather in the changes appropriately. I rebuilt the Visual Studio "console" project (client & server sides) & was able to run the simple server/client test in the code - output provided in console windows.
