Add Worker Thread in Source Filter derived from CSource class

How to create threads within CSource derived class.
within PushDesktop Source Filter,I created the thread. within this thread, I incremented the integer.within FillBuffer() fn, I displayed the integer value.
ThreadProc() {
i++; SetEvent( m_hEvent); }
FillBuffer() { WaitForSingleObject( m_hEvent);
}
the following code is not working ;
ThreadProc() {
while(true) {
dwWaitObject = WaitForSingleObject(m_hStopEvent, 5);
if(dwWaitObject == WAIT_OBJECT_0) { return 0; }
i++;
SetEvent( m_hEvent);
}
}
FillBuffer()
{
WaitForSingleObject( m_hEvent);
}
ThreadProc() {
i++; SetEvent( m_hEvent); }
FillBuffer() { WaitForSingleObject( m_hEvent);
}

At every one second, the video renderer waits for data from the source Filter. So if u modify thedwWaitObject = WaitForSingleObject(m_hStopEvent, 5); as
dwWaitObject = WaitForSingleObject(m_hStopEvent, 2); then it is working.
we must not take that much of time ...
Try with one more thing:
ThreadProc() { ThreadCB(); }
ThreadCB() { WaitForSingleObject(); printf("\n sundar");
}
