Simple Worker Thread Example

Environment: VC6 SP4, NT4 SP6

This example demonstrates how to start a worker thread from a dialog, keeping the dialog free while running a busy loop in the background. The first of three loops is run from an OnButton event by declaring a variable and calling a function from CloopClass. This is to demonstrate that the dialog can't be moved while the loop is running. The second loop is contained within the thread controller function, which starts after the first loop is done. This allows one to move the dialog while the loop runs. The third loop is created as the first one but from within the worker thread instead of the dialogs OnButton event. The dialog is still free to move while the third loop runs.
