ok, here's my advice:
- You won't be able to write to your c: drive afaik.
- You can't find the file on the file system? Do you mean your
computers file system or the emulators file system? It should be on
the emulator in /data/data/<your.app.namespace>/files/out.txt.
- I don't think there would be a permissions problem for either the
file or http examples you gave.
- Your http post code looks ok at first glance. Are you getting any
exceptions with it?
Why do you need to write something to C: anyway? Are you working on
some kind of development tool?
