Answer 2

I've googled a lot and found some infomation about "PerformanceCounter",but obviously I dont know how that works exactly . And I also get a view on WMI in wiki,definitely beyond me.I only have some knowledge about WIN API and MFC lib.   

Answer 3

Answer 6

Sorry,guys for no reply being a while

   I've had my problem solved.I got memory usage as Nikita Leontiev pointed out.Only one problem,the result of memorywoekingset is always larger than that in the Windows Task Manager.And I got  cpu usage by querying "ntdll.dll",which I was told by my friend.

   Anyway,Thanks to you all.
