说明：  一款稳定的VB多线程例子源码，运行实例后，每个线程单独运行，框内一条竖线各自运行互不影响，本线程占用系统资源极少，而且较稳定，是值得大家借鉴的一款不错的多线程模块。
(A stable VB multithreaded example source code, running instances, each thread is run separately, a vertical bar box each run independently of each other, very little this thread consumes system resources, and more stable, is worth learning a good multi-threaded module.)
