Set the start function of the multimedia timer as a member function!

In order to avoid using Sleep, it is best to make another thread, but if the thread is processed, if it is a global function, the member variables and member functions of the class cannot be invoked and processed, in order to process member variables and member functions in the thread, The following is the example of what I did through a certain conversion!
