relevant code? can you give me some more details about the relevant code ?

1. A thread that does one thing then exits its thread function

   
   The auxiliary thread exits of its own volition. The main thread can then check that the thread has exitted using the GetExitCodeThread[^] function (the functions shows a thread exit code of STILL_ACTIVE if the thread hasn't terminated), or can wait for the thread to exit using the WaitForSingleObject[^] function, using the thread handle as the handle to wait for (a thread's handle is set when the thread exits).

2. A thread that does many things in a loop

   
   In this case, you need some way of telling the thread that it's time to exit. In general, you could use a boolean flag that the thread can check each time round the loop (use InterlockedExchange[^] to set the flag from the main thread) or you could use an event[^] - the main thread would set the event to indicate that the other thread should exit, the other thread use WaitForSingleObject to see if the event's been set). In either case, the main thread would notify the other thread that it's time to exit, then wait for the thread to exit using WaitForSingleObject.

Since this is a non-Unicode application, you need to make sure that your "Language for non-Unicode programs" is set to Chinese (Simplified) and reboot.  It then should work.  (If you are on an English os and running a language pack, changing to the language pack does not automatically change the "Language for non-Unicode programs".  This is done manually).
