delphi读cpu序列号问题

Question

下面代码大家帮测试下。是不是都能获得值。有错误弹出没？？function GetCpuInfo(): string;
var
  R: array[0..19] of Char;
  CID: Integer;
begin
  FillChar(R, 20, 0);
  asm
    push ebx
    push ecx
    push edx
    mov eax, 0
    cpuid
    mov dword ptr R[0], ebx
    mov dword ptr R[4], edx
    mov dword ptr R[8], ecx
    mov eax, 1
    cpuid
    mov CID, edx
    pop edx
    pop ecx
    pop ebx
  end;
  Result := R + inttostr(CID);
end;

Answer 1

运行showmessage(GetCpuInfo);能获得cpu号，没错误提示。

Answer 2

没错误,但乱码(win7 64 + delphi 2010)

Answer 3

另一方法,用WMI，你可得到你所有想要的，且兼容所有windows系统implementation
 uses ActiveX, ComObj;
{$R *.dfm}
function GetWMIProperty(WMIType, WMIProperty:String):String;
var
  Wmi, Objs, Obj:OleVariant;
  Enum:IEnumVariant;
  C:Cardinal;
begin
  try
    Wmi:= CreateOleObject('WbemScripting.SWbemLocator');
    Objs := Wmi.ConnectServer('.','root\cimv2').ExecQuery('Select * from Win32_'+ WMIType);
    Enum:=IEnumVariant(IUnknown(Objs._NewEnum));
    Enum.Reset;
    Enum.Next(1,Obj,C);    
    Obj:=Obj.Properties_.Item(WMIProperty,0).Value;
    if VarIsArray(Obj) then Result:=Obj[0]
    else Result:=Obj;
    except
     Result:='error';
  end;
end;procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage(GetWMIProperty('BIOS','BIOSVersion'));          //获得BIOS版本
  ShowMessage(GetWMIProperty('DiskDrive','SerialNumber'));     //获得第一块硬盘的设备标示
  ShowMessage(GetWMIProperty('Processor','ProcessorId'));     //获得CPUID。
end;

Answer 4

delphi7 + win2003GetCpuInfo没有出错误,不知道结果对不对出错误
ShowMessage(GetWMIProperty('DiskDrive','SerialNumber'));     //获得第一块硬盘的设备标示

Answer 5

keiy
我也是 d7 + win2003 读硬盘出错。
cpuid 是 16进制吧。跟我的函数不同(10进制？).

Answer 6

我试过很多，只有这代码能读硬盘序列号。对比windows优化大师是对的.

Answer 7

to:jianye112 你这个程序,在我BDS2010下编译运行,结果为乱码
toall:我的程序.包括jianye112的两个程序,在winxp+bcb6下编译运行都没问题
将它们的exe文件copy到win7 64位下也都没问题
可能还是bds2010下unicode的问题,研究下先

Answer 8

果然是String的问题
改进后的,可在2010版本编译通过 function GetWMIProperty(WMIType, WMIProperty:AnsiString):String;
var
  Wmi, Objs, Obj:OleVariant;
  Enum:IEnumVariant;
  C:Cardinal;begin
  try
    Wmi:= CreateOleObject(AnsiString('WbemScripting.SWbemLocator'));
    Objs := Wmi.ConnectServer(AnsiString('.'),AnsiString('root\cimv2')).ExecQuery(AnsiString('Select * from Win32_'+WMIType));   Enum:=IEnumVariant(IUnknown(Objs._NewEnum));
    Enum.Reset;
    Enum.Next(1,Obj,C);
    Obj:=Obj.Properties_.Item(WMIProperty,0).Value;
    if VarIsArray(Obj) then Result:=Obj[0]
    else Result:=Obj;
    except
     Result:='error';
  end;
end;
WMI可得到所有系统信息,硬件/软件/服务(包括远程机上的)

Answer 9

应该是 delphi 版本问题吧。

就是 wmi读cpuid的速度在d7+win2003要1-3秒左右
