1、获取CPU名称：
获取HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0子键中获取ProcessorNameString的键值。该注册表子键存储了当前计算机的处理器信息，如CPU名称、标识和厂商等。
void CSystemHardwareInfoDlg::OnButton1(){
CString strPath="HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0"
CRegKey regKey
LONG lResult
lResult=regKey.Open(HKEY_LOCAL_MACHINE,LPCTSTR(strPath),KEY_ALL_ACCESS)
//打开注册表主键
if (lResult!=ERROR_SUCCESS)//读取键值不成功
{
AfxMessageBox("错误：无法查询有关的注册表信息")
return
}
char chCPUName[50]
DWORD dwSize=50
regKey.QueryValue(chCPUName,"ProcessorNameString",&dwSize)
//获取RegisteredOwner的值
m_strCPUName=chCPUName
UpdateData(FALSE)
regKey.Close()//关闭注册表
}
2、获取CPU标识 ：
获取HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0子键中获取Identifier的键值。
void CSystemHardwareInfoDlg::OnButton2() 租旁凯{
CString strPath="HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0"
CRegKey regKey
LONG lResult
lResult=regKey.Open(HKEY_LOCAL_MACHINE,LPCTSTR(strPath),KEY_ALL_ACCESS)
//打开注册表主键
if (lResult!=ERROR_SUCCESS)//读取键值启姿不成功
{
AfxMessageBox("错误：无法查询弊唤有关的注册表信息")
return
}
char chCPUID[50]
DWORD dwSize=50
regKey.QueryValue(chCPUID,"Identifier",&dwSize)
//获取RegisteredOwner的值
m_strCPUIdentifier=chCPUID
UpdateData(FALSE)
regKey.Close()//关闭注册表
}
3、获取CPU制造商名称 ：
获取HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0子键中获取VendorIdentifier的键值。
void CSystemHardwareInfoDlg::OnButton3(){
CString strPath="HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0"
CRegKey regKey
LONG lResult
lResult=regKey.Open(HKEY_LOCAL_MACHINE,LPCTSTR(strPath),KEY_ALL_ACCESS)
//打开注册表主键
if (lResult!=ERROR_SUCCESS)//读取键值不成功
{
AfxMessageBox("错误：无法查询有关的注册表信息")
return
}
char chVendor[50]
DWORD dwSize=50
regKey.QueryValue(chVendor,"VendorIdentifier",&dwSize)
//获取RegisteredOwner的值
m_strVendorID=chVendor
UpdateData(FALSE)
regKey.Close()//关闭注册表
}
4、获取CPU主频 ：
获取HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0子键中获取~MHz的键值。注意为DWORD类型。
void CSystemHardwareInfoDlg::OnButton4(){
CString strPath="HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0"
CRegKey regKey
LONG lResult
lResult=regKey.Open(HKEY_LOCAL_MACHINE,LPCTSTR(strPath),KEY_ALL_ACCESS)
//打开注册表主键
if (lResult!=ERROR_SUCCESS)//读取键值不成功
{
AfxMessageBox("错误：无法查询有关的注册表信息")
return
}
DWORD dwMHz
DWORD dwSize=50
regKey.QueryValue(dwMHz,"~MHz")
//获取RegisteredOwner的值
m_nMHz=dwMHz
UpdateData(FALSE)
regKey.Close()//关闭注册表
}
