如何获得系统的内存使用情况和cpu负载情况？
用VC实现。

关于内存的绝大多数信息可以通过以下函数获得：

BOOL GetProcessMemoryInfo(
HANDLE Process, // handle to process
PPROCESS_MEMORY_COUNTERS ppsmemCounters, // buffer
DWORD cb // size of buffer
);

The GetProcessMemoryInfo function retrieves information about the memory usage of the specified process in the PROCESS_MEMORY_COUNTERS structure.

typedef struct _PROCESS_MEMORY_COUNTERS {
DWORD cb;
DWORD PageFaultCount;
SIZE_T PeakWorkingSetSize;
SIZE_T WorkingSetSize;
SIZE_T QuotaPeakPagedPoolUsage;
SIZE_T QuotaPagedPoolUsage;
SIZE_T QuotaPeakNonPagedPoolUsage;
SIZE_T QuotaNonPagedPoolUsage;
SIZE_T PagefileUsage;
SIZE_T PeakPagefileUsage;
} PROCESS_MEMORY_COUNTERS;
typedef PROCESS_MEMORY_COUNTERS *PPROCESS_MEMORY_COUNTERS;

获得cpu时间:
BOOL GetProcessTimes(
HANDLE hProcess, // handle to process
LPFILETIME lpCreationTime, // process creation time
LPFILETIME lpExitTime, // process exit time
LPFILETIME lpKernelTime, // process kernel-mode time
LPFILETIME lpUserTime // process user-mode time
);

关于io信息：
BOOL GetProcessIoCounters(
HANDLE hProcess, // handle to process
PIO_COUNTERS lpIoCounters // I/O accouting information
);
