ReplyJust what I needed; simple, worked first time (once I corrected the syntax and typos); thanks!

I wrote something very similar but my fear is that the CPU will switch and start another thread before the first one has a chance to exit the _ThreadFunc(). Is there a chance of this?

in general, this class is normal.but i write a counter in Run(), and Set counter to a window text.following code show this:
Run()
{
int i = 0;
while (true)
{
char buf[100];
wsprintf(buf, "%d", i);
SetWindowText(m_hWnd, buf);
if (m_Terminated)
break;
}
}
it is can exit normally. why?

How to get a thread handle, knowing the thread ID (from Thread32Next() function)?

The threads can then identify themselves, and the
HANDLE CreateThread(
I had the same problem, with a multithreaded program,
and used the returned handle from CreateThread, as well
as the ThreadID to track the threads. I saved them in an
array ( DWORD, same as Hndl ), and passed the thread
an index to this array in the lpParameter.
controlling program can access each thread using the
thread handle and/or threadID
LPSECURITY_ATTRIBUTES lpThreadAttributes, // Security Descriptor
DWORD dwStackSize, // initial stack size
LPTHREAD_START_ROUTINE lpStartAddress, // thread function
LPVOID lpParameter, // thread argument
DWORD dwCreationFlags, // creation option
LPDWORD lpThreadId // thread identifier
);

Some other thread might still be using pointers that reference data contained on the terminated thread's stack, if these other threads attempted to access the stack, an access violation could occur.
For more details kindly refer the book
If a thread is terminated by TerminateThread(), The stack for that particular thread os released only when the process that owns it is terminated. This could also lead to access violation due to the following reasons

You can find out the current state of the thread by using
DWORD WaitForSingleObject(
HANDLE hHandle, // handle to object to wait for
DWORD dwMilliseconds // time-out interval in milliseconds
);
This function returns with exit code WAIT_OBJECT_0, if the thread is currently in the signalled state. Otherwise it will return you a WAIT_TIMEOUT result.
