From: Mani on 16 Apr 2010 05:13 Hi, I Have no idea about performance counter in windows vista. Can any one pelase tell me, Is it possible to reset the peformance counter in windows vista by using MFC with ATL?. If it possible means, please explain me. --- frmsrcurl: http://msgroups.net/microsoft.public.vc.mfc/
From: Joseph M. Newcomer on 16 Apr 2010 09:42 There is an unfortunate fixation on OO programming that says "every capability of the OS is exposed by way of some MFC or ATL class" and this is simply not true. If you know how to read a performance counter, you just read it as if you never heard of MFC or ATL. If you want to write a class to do it, feel free. Not every OS capability has a class to go with it. joe On Fri, 16 Apr 2010 02:13:53 -0700, Mani <user(a)msgroups.net/> wrote: >Hi, > > I Have no idea about performance counter in windows vista.

But the minimum Performance Counter API should work the same in all OSes. -- Joseph M.

Somebody wrote a class called CCPUTicker. It encapsulates the RDTSC assembly instruction. It's old and I don't know of multiple cpu(cores) support, neither of OS version support. And I doubt that there is any way at all to modify the counter. But have a look. Hans |
