Passing an argument through threads

Overburn

I have a long procedure that i would like to have run on its own thread, but
the procedure requires a variable that I would pass to it.. I would like to
avoid using a global variable. Can someone show me how to pass a variable
through a threaded function.
 
I was reading the VS Help file on the "setData" method. Couldn't that be
used in this instance, It seems like it is saying that I can set a certain
slot set to a specified value for a specified type. Only reason I ask is
because my program isn't ready for a test run or else I would try it out...
