I have a thread class and I want to be able to track its usage within
an application. FYI the class launches aplications in their own thread
when the 'launch' method is called.
That works OK
However I want to take things a bit further and my thinking was that I
could use a class parameter to do a count but I am having no luck I am
afraid.
Its 'GlobalThreadCount' I am trying to get to work. I may need to use
the globals built in - or do I.
Thanks in advance
David
