Answer 3

fatal error C1083: Cannot open include file: 'wbemidl.h' 怎么办啊。在线等、、、、

Answer 4

是不是vc的版本太低，sdk需要升级

Answer 5

vc6的sdk版本太低了，最好下一个sdk，更新一下

Answer 6

请问用WMI能取硬件详细信息吗？比如内存或硬盘制造商、转速等。

Answer 7

请高人指教。
   Win32_CacheMemory 
      Win32_CDROMDrive 
      Win32_CurrentProbe 哪位高人对这些有研究的给我来一份吧。

Answer 8

顶啊。来高人啊。class Win32_MemoryDevice : Win32_SMBIOSMemory
{
  uint16 Access;
  uint8 AdditionalErrorData[];
  uint16 Availability;
  uint64 BlockSize;
  string Caption;
  uint32 ConfigManagerErrorCode;
  boolean ConfigManagerUserConfig;
  boolean CorrectableError;
  string CreationClassName;
  string Description;
  string DeviceID;
  uint64 EndingAddress;
  uint16 ErrorAccess;
  uint64 ErrorAddress;
  boolean ErrorCleared;
  uint8 ErrorData[];
  uint16 ErrorDataOrder;
  string ErrorDescription;
  uint16 ErrorGranularity;
  uint16 ErrorInfo;
  string ErrorMethodology;
  uint64 ErrorResolution;
  datetime ErrorTime;
  uint32 ErrorTransferSize;
  datetime InstallDate;
  uint32 LastErrorCode;
  string Name;
  uint64 NumberOfBlocks;
  string OtherErrorDescription;
  string PNPDeviceID;
  uint16 PowerManagementCapabilities[];
  boolean PowerManagementSupported;
  string Purpose;
  uint64 StartingAddress;
  string Status;
  uint16 StatusInfo;
  string SystemCreationClassName;
  boolean SystemLevelAddress;
  string SystemName;
};如上，内存属性，没有制造商的属性，那怎么取制造商呢？

Answer 9

呵呵，谁高人啊。我是叫高人帮我看看啊。上面class Win32_MemoryDevice : Win32_SMBIOSMemory 这是CSDN的。
