GlobalMemoryStatusEx函数用于获取系统内存信息：

BOOL WINAPI GlobalMemoryStatusEx(
__inout LPMEMORYSTATUSEX lpBuffer
);

示例代码：

void CTestDlg::GetMemoryInfo()
{
MEMORYSTATUSEX statex;

statex.dwLength = sizeof (statex);

GlobalMemoryStatusEx(&statex);

CString strInfo = "内存：\r\n";
CString strTemp = "";
// 内存使用率
strTemp.Format("There is %ld percent of memory in use.\r\n", statex.dwMemoryLoad);
strInfo += strTemp;
// 物理内存
strTemp.Format("There are %I64d total Kbytes of physical memory.\r\n", statex.ullTotalPhys/1024);
strInfo += strTemp;
// 可用物理内存
strTemp.Format("There are %I64d free Kbytes of physical memory.\r\n", statex.ullAvailPhys/1024);
strInfo += strTemp;
// 认可用量：总数
strTemp.Format("There are %I64d total Kbytes of paging file.\r\n", statex.ullTotalPageFile/1024);
strInfo += strTemp;
// 认可用量：未用
strTemp.Format("There are %I64d free Kbytes of paging file.\r\n", statex.ullAvailPageFile/1024);
strInfo += strTemp;
// 虚拟内存
strTemp.Format("There are %I64d total Kbytes of virtual memory.\r\n", statex.ullTotalVirtual/1024);
strInfo += strTemp;
// 可用虚拟内存
strTemp.Format("There are %I64d free Kbytes of virtual memory.\r\n", statex.ullAvailVirtual/1024);
strInfo += strTemp;
// ullAvailExtendedVirtual保留字段
strTemp.Format("There are %I64d free Kbytes of extended memory.\r\n", statex.ullAvailExtendedVirtual/1024);
strInfo += strTemp;

m_staticMemory.SetWindowText(strInfo);
}

运行结果：
