Visual Basic Threads - Beginner informations

Question

I'm having a simple beginner question about Threads in Visual Basic (2010): If I start a sub as a new thread and in this sub, an other sub is called.

Is this one also running inside this additional thread?

private sub output (...
  output1
  outout2
  ...
end sub

private sub IsGonnaBeAnExtraThread(..
  ...
  output(..)
  ...
end sub

Answer 1

If you execute sub1 in a threadA and if sub1 calls sub2, then sub2 and all procedures called by sub2 will be executed in thread A.
