Qt 使用WINDOWS API读取SMBIOS信息，并通过CMD命令打印相关信息，参考DumpSMBIOS项目

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 0DWORD 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-getsystemfirmwaretableneedBufferSize = 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)
{IWbemServices *  pSvc = NULL;IWbemServices *  pSvcSmbios = NULL;IWbemLocator *   pLoc = NULL;HRESULT            result;IEnumWbemClassObject *  pEnumerator = NULL;std::wostringstream     query;std::wstring            q;IWbemClassObject *      pInstance = NULL;VARIANT                 vtProp;ULONG                   uReturn = 0;CIMTYPE                 pvtType;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);if (!SUCCEEDED(result)) {CoUninitialize();return false;}result = CoCreateInstance(CLSID_WbemLocator, 0, CLSCTX_INPROC_SERVER, IID_IWbemLocator, (LPVOID *)&pLoc);if (!SUCCEEDED(result)) {CoUninitialize();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;}result = pLoc->ConnectServer(_bstr_t(L"ROOT\\WMI"), NULL, NULL, 0, NULL, 0, 0, &pSvcSmbios);if (!SUCCEEDED(result)) {pLoc->Release();CoUninitialize();return false;}result = CoSetProxyBlanket(pSvcSmbios, 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)) {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();if (pSvc)pSvc->Release();if (pLoc)pLoc->Release();CoUninitialize();return true;
}

自定义结构体 - 实际获取数据结构

将DumpSMBIOS项目中打印的字段封装成结构体，转换数据时保存，不只是输出内容

#pragma region "获取 SMBIOS 指定数据(指定结构转换)" {typedef struct _W_TYPE_0_ {PWCHAR Vendor;PWCHAR Version;PWCHAR Date;//pBIOS->Header.Length > 0x14DWORD SysVersion=0;DWORD ECVersion=0;
}W_BIOSInfo;typedef struct _W_TYPE_1_

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* LocateStringA(const char* str, UINT i)
{static const char strNull[] = "";if (0 == i || 0 == *str) return strNull;while (--i){str += strlen((char*)str) + 1;}return str;
}#define GetData(_STR_,_IN_VAL_,_OUT_VAL_,val)                                       \
{                                                                                   \const char* c_##val = LocateStringA(_STR_, _IN_VAL_);                           \const int n_##val = (int) strlen(c_##val);                                      \_OUT_VAL_= new WCHAR[n_##val + 1];                                              \if (_OUT_VAL_)                                                                  \
{                                                                               \SecureZeroMemory(_OUT_VAL_, sizeof(WCHAR) * (n_##val + 1));                 \MultiByteToWideChar(CP_ACP, NULL, c_##val, n_##val, _OUT_VAL_, n_##val + 1);\}                                                                               \}//将UChat转换为PWCHAR数据

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/89959755a.exit(0);return 0;//    return a.exec();
}
