I have been taught (by someone else) to pass an object reference in 
lparam (as a void *), then convert it back to the object and call a 
member function.

So my questions are these.
1. Is this bad practice? Should I push my objects onto a queue and 
process them in the thread funtion (dealing with contention for the 
queue with a mutex or semaphore)?

2. Does the member function that I call in the thread function execute 
in the thread's "space"? Or does it execute in in the main thread's "space"?

Thanks,
Ian
