I don't use threads, but will bear that one in mind.

This project shows how you can resolve a 'dumb' pointer to an object
obtained via the hidden VB ObjPtr() function back into a fully referenced
object reference on which you can call methods and set properties. The
first time I saw this concept was in Bruce McKinney's book "Hardcore Visual
Basic" so Mr. Mckinney deserves any credit for the idea behind the demo.
And wonder if there is any good use for this. I know this is finding a
problem for a solution, but I have a feeling, that
this might have some practical use.
In the distant past, I've used this technique for sharing an object instance
across multiple threads...
