Setting optional parameter stepToStoreResultsIn of Thread.WaitForEnd() method

[freak]

This question is  related to an earlier posting of mine regarding launching a thread from a c++ code module (http://forums.ni.com/ni/board/message?board.id=330&message.id=15383&query.id=775150#M15383). I am launching a new thread from a code module (c++ DLL), and I need wait for it to finish.

There are 2 ways I envision doing this:

1. wait for the new thread to finish before returning from my code module by calling Thread.WaitforEnd()

2. return a reference to the new thread to the calling sequence and make the calling sequence wait for the thread to complete before terminating using a wait step at the end of the sequence. 

My questions are regarding method 1, where I would call Thread.WaitforEnd(). I want to set the parameter stepToStoreResultsIn to set the result of the step in the calling sequence to the result of the sequence executed in the new thread:

a. Do I understand the purpose of the stepToStoreResultsIn parameter correctly?

b. The stepToStoreResultsIn parameter must be a variant, so how do I pass in the step context as a variant? is it the same as a IDispatch pointer?

a. Yes

b. Yes
