That writes the return value of ShellExecute() to the file, which is exactly what you're seeing. It doesn't magically know you want to redirect the other program's input to your own file object (which wouldn't work anyway, since they're different processes).
Since this is a console app, you can use popen() to capture the output. Or more generally, you can set up a pipe to the file and use CreateProcess() to tell psinfo the pipe handle.

CArchive has no concept, that is exposed to the user, of file position based on what it has serialized just more like a buffer position internally
