看看下面的例子：
一、 用GetDriveType函数获取磁盘信息
Lbl_DriveType:Tlabel;
DriveType:WORD; //定义驱动器类型变量
DriveType:=GetDriveType(RootPathName); //获得RootPathName所对应的磁盘驱动器信息
case DriveType of
DRIVE_REMOVABLE:Lbl_DriveType.Caption:= '软盘驱动器';
DRIVE_FIXED : Lbl_DriveType.Caption:= '硬盘驱动器';
DRIVE_REMOTE: Lbl_DriveType.Caption:= '网络驱动器';
DRIVE_CDROM: Lbl_DriveType.Caption:= '光盘驱动器';
DRIVE_RAMDISK: Lbl_DriveType.Caption:= '内存虚拟盘';
end; //将该磁盘信息显示在Lbl_DriveType中
二、 用GlobalMemoryStatus函数获取内存使用信息
MemStatus: TMEMORYSTATUS; //定义内存结构变量
Lbl_Memory:Tlabel;
MemStatus.dwLength := size of(TMEMORYSTATU?
S);
GlobalMemoryStatus(MemStatus); //返回内存使用信息
Lbl_Memory.Caption := format('共有内存: %d KB 可用内存: %dKB',[MemStatus.dwAvailPhys div 1024,MemStatus.dwTotalPhys div 1024]);
//将内存信息显示在Lbl_Memory中
三、 用GetSystemInfo函数获取CPU信息
SysInfo: TSYSTEMINFO;
Lbl_CPUName:Tlabel;
GetSystemInfo(SysInfo);//获得CPU信息
case SysInfo.dwProcessorType of
PROCESSOR_INTEL_386:Lbl_CPUName.Caption:=format('%d%s',[SysInfo.dwNumber Of Processors,'Intel80386']);
PROCESSOR_INTEL_486:Lbl_CPUName.Caption:=format('%d%s',[SysInfo.dwNumber Of Processors, 'Intel 80486']);
PROCESSOR_INTEL_PENTIUM:Lbl_CPUName.Caption:=format('%d%s',[SysInfo.dwNum
berOfProcessors, 'Intel Pentium']);
PROCESSOR_MIPS_R4000:Lbl_CPUName.Caption:=format('%d%s',[SysInfo.dwNumberOfProcessors, 'MIPS R4000']);
PROCESSOR_ALPHA_21064:Lbl_CPUName.Caption:=format('%d%s',[SysInfo.dwNumberOfProcessors, 'ALPHA 21064']);
end;//把CPU信息显示在Lbl_CPUName中。(
