CreateThread works in VB, and it works surprisingly well.  The BIG issue
is that VB isn't all thread safe.  It isn't billed as thread safe.  So
creating a thread may or may not step on something that it shouldn't
depending on what your thread does.

It's a huge "use at your own risk" item.

You can do multithreading in another way, and really well.  MSDN
(shockingly) has a really good example called CoffeePot that has
multithreading with inter-thread communication.  It's a great sample
that you should work through if you're serious about multithreading.

The CreateThread API is a big no no in Visual Basic. Only if you are
willing to spend hours coding you can make it works, just to see it
failing when you run VB with a different service pack. I am not saying
that it should be avoid, but you have to use it at your own risk. The
best documentation I found is on Daniel Appleman's 
books (you can find good articles in his company web site, 
www.desaware.com)
If the code that uses CreateThread was not written by you, I would
consider using a different solution to the problem (ActiveX exe is the
VB way to implement multiple thread, it is easy and working is
guaranteed)
