在获取PE系统中的CPU、主板、内存信息时，发现使用WMI部分信息无法获取，通过gitGub上的DumpSMBIOS完全解决了这个问题，并单独做成了个案例，以下示例和代码都是参考DumpSMBIOS项目
SMBIOS这个数据还是用到的比较少。但是DumpSMBIOS项目有很多方面直接学习借鉴的东西。

SMBIOS 读取
详见DumpSMBIOS源码，此处只是对修改的部分代码进行一个总结，关键代码的整理
结构体对齐
在DumpSMBIOS示例中，SMBIOS读取的数据有13种类型，每种都对应结构体，并使用
#pragma pack 对齐字节，对齐字节获取数据在Windows API中很常见。
也难怪面试总有人喜欢问数据类型占几个字节的问题，
在通信方面，结构体对齐读取数据流应该方便得多。
#pragma pack(push)
#pragma pack(1)
#define WAKEUP_TYPE_COUNT 9
#define BOARD_TYPE_COUNT 13

读取SMBIOS数据
DumpSMBIOS使用两种方式读取SMBIOS数据
GetSystemFirmwareTable和WMI；
GetSystemFirmwareTable
使用 GetSystemFirmwareTable 函数读取原始 SMBIOS 固件表
void Lib_Smbios::initialization()
{
// GET_SYSTEM_FIRMWARE_TABLE pGetSystemFirmwareTable = (GET_SYSTEM_FIRMWARE_TABLE)GetProcAddress(GetModuleHandle(L"kernel32"), "GetSystemFirmwareTable");
LPBYTE pBuff = NULL;
PBYTE tableStart = nullptr;
UINT nTableLength = 0;
DWORD needBufferSize = 0;
const DWORD Signature = 'RSMB';
#if 0
DWORD Signature = 'R';
Signature = (Signature << 8) + 'S';
Signature = (Signature << 8) + 'M';
Signature = (Signature << 8) + 'B';
#endif
//从固件表提供程序检索指定的固件表。
//https://learn.microsoft.com/zh-cn/windows/win32/api/sysinfoapi/nf-sysinfoapi-getsystemfirmwaretable
needBufferSize = GetSystemFirmwareTable(Signature, 0, NULL, 0);
pBuff = new BYTE[needBufferSize];
needBufferSize = GetSystemFirmwareTable(Signature, 0,pBuff,needBufferSize);
if (needBufferSize > 0) {
const PRawSMBIOSData pDMIData = (PRawSMBIOSData)pBuff;
MajorVersion = pDMIData->MajorVersion;
MinorVersion = pDMIData->MinorVersion;
DMIRevision = pDMIData->DmiRevision;
tableStart = (PBYTE) & (pDMIData->SMBIOSTableData);
nTableLength = pDMIData->Length;
}
if ((0 == needBufferSize) || (nTableLength > needBufferSize))
{
if (getWmiSmbios(&pBuff, &nTableLength))
tableStart = pBuff;
}
if (tableStart)
ParseSMBIOSStruct(tableStart, nTableLength);
if (pBuff)
delete[] pBuff;
}
WMI
使用 WMI 检索 SMBIOS 属性。 Win32 类中包含许多单独的属性。 还可以使用 MSSMBios_RawSMBiosTables 类在单个缓冲区中检索原始 SMBIOS 数据。
bool Lib_Smbios::getWmiSmbios(BYTE ** data, UINT * length)

VARIANT vtProp;
ULONG uReturn = 0;

result = CoInitialize(NULL);
if (!SUCCEEDED(result))
return false;
result = CoInitializeSecurity(NULL, -1, NULL, NULL, RPC_C_AUTHN_LEVEL_DEFAULT, RPC_C_IMP_LEVEL_IMPERSONATE, NULL, EOAC_NONE, NULL);

return false;
}
result = pLoc->ConnectServer(_bstr_t(L"ROOT\\CIMV2"), NULL, NULL, 0, NULL, 0, 0, &pSvc);
if (!SUCCEEDED(result)) {
pLoc->Release();
CoUninitialize();
return false;
}
result = CoSetProxyBlanket(pSvc, RPC_C_AUTHN_WINNT, RPC_C_AUTHZ_NONE, NULL, RPC_C_AUTHN_LEVEL_CALL, RPC_C_IMP_LEVEL_IMPERSONATE, NULL, EOAC_NONE);
if (!SUCCEEDED(result)) {
pLoc->Release();
CoUninitialize();
return false;
}

return false;
}

if (!SUCCEEDED(result)) {
pSvcSmbios->Release();
pSvc->Release();
pLoc->Release();
CoUninitialize();
}
result = pSvcSmbios->CreateInstanceEnum(bstr_t(L"MSSMBios_RawSMBiosTables"), 0, NULL, &pEnumerator);
if (SUCCEEDED(result)) {
while (pEnumerator) {
result = pEnumerator->Next(WBEM_INFINITE, 1, &pInstance, &uReturn);
if (!uReturn) {
break;
}
VariantInit(&vtProp);
result = pInstance->Get(bstr_t("SMBiosData"), 0, &vtProp, &pvtType, NULL);
if (SUCCEEDED(result)) {
SAFEARRAY * array = V_ARRAY(&vtProp);
*length = array->rgsabound[0].cElements;
*data = new BYTE[*length];
memcpy(*data, (BYTE*)array->pvData, *length);
VariantClear(&vtProp);
}
}
pEnumerator->Release();
if (pInstance)
pInstance->Release();
}
if (pSvcSmbios)
pSvcSmbios->Release();

结构体数据转换
其中需要注意的是 CP_ACP 与 CP_OEMCP 的使用，
测试时使用CP_OEMCP数据乱码，
但是 DumpSMBIOS 项目中使用 CP_OEMCP输出正常，脑壳痛。

{
static const char strNull[] = "";
if (0 == i || 0 == *str) return strNull;
while (--i)

QT CMD命令行输出
之前看到某些软件既可以CMD命令行输出数据，又可以打开界面操作的时候，我就尝试过使用QT实现类似的功能。
通过console控制台程序与可执行程序放在同级目录实现，如果argc参数个数大于1就是console打印数据，否则就打开同级目录下的可执行程序，但是这样一来启动的可执行程序的时候始终会有console控制台程序一闪而逝。这个问题始终没有解决、、、
其他方法 隐藏控制台窗体
通过在main.cpp添加这段，确实能隐藏console打开，但是需要的console输出内容就没了，这只适用于隐藏不显示console控制台。
//Qt 隐藏控制台窗体
//#pragma comment( linker, "/subsystem:\"windows\" /entry:\"mainCRTStartup\"" )
通过ShowWindow隐藏控制台也只是加快了隐藏的速度，还是能看见console控制台程序一闪而逝。
HWND consoleWindow = GetConsoleWindow(); // 获取控制台窗口句柄
// 隐藏窗口
ShowWindow(consoleWindow, SW_HIDE);
值得注意的是如果需要打印数据后自动退出程序就需要修改main的返回值
完整示例：
//Qt 隐藏控制台窗体
//#pragma comment( linker, "/subsystem:\"windows\" /entry:\"mainCRTStartup\"" )
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
if(argc==1)
{
HWND consoleWindow = GetConsoleWindow(); // 获取控制台窗口句柄
// 隐藏窗口
ShowWindow(consoleWindow, SW_HIDE);
QProcess* process=new QProcess();
process->startDetached("Computer_INFO.exe");
process->waitForStarted(-1);
}
else
{
Lib_Command_Out out;
out.OpeaType(argc, argv);
}
//退出事件循环
//https://blog.csdn.net/qq_21078557/article/details/89959755
a.exit(0);
return 0;
// return a.exec();
