In Search of Robust, Secure IPC for .NET
By Shawn Van Ness, December 01, 2003
.NET Remoting Services are the recommended solution for IPC in .NET, but there are many scenarios where .NET Remoting won't work. Shawn shows how to get simple, intrasession IPC messaging in .NET by creating a managed library for good old Dynamic Data Exchange (DDE).
In Search of Robust, Secure IPC for .NET
Listing 1 Base class and interface definitions for IPC architecture
namespace Jitsu.Ipc
{
public interface IMessageSink
{
void AcceptMessage(byte[] payload);
}
public abstract class IpcEndpoint
{
// Create a client-side connection to the IPC endpoint.
public abstract IpcClient Connect();
// Create the server-side of an IPC endpoint, and
// begin listening for messages.
public abstract IpcServer Listen();
}
public abstract class IpcClient :
IMessageSink, IDisposable
{
// Send a message to the IPC endpoint (implements IMessageSink).
public abstract void SendMessage(byte[] payload);
// Close the client-side of the connection
// (implements IDisposable).
public abstract void Close();
}
public abstract class IpcServer : IDisposable
{
// Begin listening for messages (blocks until StopListening
// is called). Incoming messages are routed to the app's
// IMessageSink callback.
public abstract void StartListening(IMessageSink callback);
// Shuts down the IPC endpoint (implements IDisposable).
public abstract void StopListening();
} }
