Write to Launcher console process?

[salmo]

I'm trying to write to the MP Launcher console from a sub-mission script. The code below works in the main mission script ie. It will write the connection status in the console window, but it fails where I put the same script in the sub-mission script.cs. I thought I might have to construct a process-writer to write from the sub-mission to the Launcher console, but I can't get this to work. Help appeciated.

I've tried this but often come up with a "System.Array does not contain a definition for StandardInput"
inputWriter = process.StandardInput; // Create the console writer (fails)
inputWriter.WriteLine("... Connected to MP game console failed.");
//process.WriteLine("... Connected to MP game console failed.");
