-Waiting for a thread has been automatically end the VC++ code, we can not just create the process, regardless of the life and death, it should learn how to collusion, or otherwise turn to the next task, the main demonstration of the code tracking process is running, and determine whether it is still running, and if so, wait for it to run the business, may wish to reference.
