Hay bob, Thanks for the reply. Just a quick point. I wasn't asking becuase of any potential performance issues. What i wanted to know is if MapViewOfFile() creates a snap shot of the MMF, at that point in time, or if it is justed used to access the MMF data. If it creates a snap shot, then as the data changes, reading it again would not make any differents. However, it seems to make know difference, although I've stuck the call within the WaitForSingleObject() Cheers.
