如何读取CPU的序列号或则其他信息？？？

[blcr]

我想读取CPU的序列号或者其他信息，但不知道如何做？请大家帮帮忙。谢谢！！！

有没有直接用VC++做的，或者一个函数直接调用？？？

[howtotell]

/*
函数：取得CPU启动到现在运行的周期数
*/
_int64 CSystemInfo::Count(void)
{
_asm
{
_emit 0x0F
_emit 0x31
}

}

/*
函数：取得CPU信息
*/
void CSystemInfo::GetCpu()
{
CString m_strCpuInfo;
m_strCpuInfo.Empty();
char OEMString[13];

int iEAXValue,iEBXValue,iECXValue,iEDXValue;

_asm {
mov eax,0
cpuid
mov DWORD PTR OEMString,ebx
mov DWORD PTR OEMString+4,edx
mov DWORD PTR OEMString+8,ecx
mov BYTE PTR OEMString+12,0
}

m_strCpuInfo.Format("%s",OEMString);

_asm {
mov eax,1
cpuid
mov iEAXValue,eax
mov iEBXValue,ebx
mov iECXValue,ecx
mov iEDXValue,edx
}

if(iEDXValue&0x800000)
{
m_strCpuInfo+=" MMX Support";
}
else
{
m_strCpuInfo+=" No MMX Support";
}
int iCPUFamily=(0xf00 & iEAXValue)>>8;

CString m_family;
m_family.Format("%s%d","\r\n Family: ",iCPUFamily);
m_strCpuInfo+=m_family;

CString Frequency;
_int64 start=Count();
Sleep(1000);
_int64 stop=Count();
UINT cpuspeed = (UINT)((stop-start)/1000000);
Frequency.Format("%d MHZ",cpuspeed);
CString cpuinfo;
cpuinfo.Format("%s%s","频率: ",Frequency);
m_strCpuInfo+=cpuinfo;
strcpy(cpu,m_strCpuInfo);

}

我要分啊 这里有个很好的类
http://www.codeproject.com/system/camel.asp

一定要给分!

[bborn]

这个类很好用
