This example shares the specific code for C++ to use MFC to obtain PC hardware configuration information for your reference. The specific content is as follows
The function is as follows, compiled using VS2010, run on XP and Win7 computers, and the annotated loop is used to test whether this method is stable:
//Included header files:#include "" #include <> #include <sstream> #include <fstream> void Cget_systemDlg::OnBnClickedButton1() { //for (int i = 0; i < 10000; i++) { std::ostringstream osConfig; (1); // Computer Name TCHAR infoBuf[512] = {0}; DWORD bufCharCount = 512; if (GetComputerName(infoBuf, &bufCharCount)) // MSDN: If the function succeeds, the return value is a nonzero value. osConfig << "Computer Name: " << infoBuf << std::endl; else osConfig << "!Error: failed to get computer name" << std::endl; // CPU CString strPath = CString("HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0"); CRegKey regKey; LONG lResult; lResult = (HKEY_LOCAL_MACHINE, strPath, KEY_READ); if (lResult == ERROR_SUCCESS) { TCHAR chCPUName[256] = {0}; DWORD dwSize = 256; LPCSTR name = "ProcessorNameString"; (chCPUName,_T("ProcessorNameString"),&dwSize); osConfig << "CPU Type: " << (char*)chCPUName << std::endl; (); } else osConfig << "!Error: failed to open register for read CPU." << std::endl; // OS Name char szOsType[MAX_PATH]; HKEY hKey; LPCTSTR StrKey="Software\\Microsoft\\Windows NT\\CurrentVersion"; if (ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_LOCAL_MACHINE,StrKey,NULL,KEY_READ,&hKey)) { DWORD dwSize = 255; DWORD dwType = REG_SZ; LPCSTR KeyValue = "ProductName"; if (ERROR_SUCCESS == ::RegQueryValueEx(hKey,KeyValue,0,&dwType,(BYTE *)szOsType,&dwSize)) osConfig << "OS : " << szOsType; else osConfig << "!Error: failed to get OS name." << std::endl; ::RegCloseKey(hKey); } else osConfig << "!Error: failed to get OS name." << std::endl; SYSTEM_INFO si; GetNativeSystemInfo(&si); // MSDN: This function does not return a value. if ( == PROCESSOR_ARCHITECTURE_AMD64 || == PROCESSOR_ARCHITECTURE_IA64 ) osConfig << " 64bits"; else osConfig << " 32bits"; OSVERSIONINFO osVer; = sizeof (OSVERSIONINFO); if (::GetVersionEx (&osVer)) // MSDN: If the function succeeds, the return value is a nonzero value. osConfig << " " << << " " << std::endl; else osConfig << "!Error: failed to get OS CSD version."; // Memory MEMORYSTATUSEX statusex; = sizeof (statusex); if (GlobalMemoryStatusEx(&statusex)) // MSDN: If the function succeeds, the return value is nonzero. { osConfig << "Installed RAM: "<< std::fixed << /1024/1024/1024.0 << "GB"; osConfig << " Free RAM: " << std::fixed << /1024/1024/1024.0 << "GB" << std::endl; } else osConfig << "!Error: failed to get RAM information." << std::endl; // Hard Drive // GetLogicalDriveStrings(sizeof(cDriveArray), cDriveArray); // MSDN: If the function fails, the return value is zero. // If the function succeeds, the return value is the length, in characters, of the strings copied to the buffer, // not including the terminating null character ULARGE_INTEGER free; ULARGE_INTEGER total; ULARGE_INTEGER totalfree; TCHAR szDriveArray[128] = {0}; TCHAR *p, *pStart; pStart = szDriveArray; p = szDriveArray; int nLen = GetLogicalDriveStrings(sizeof(szDriveArray), szDriveArray); if (nLen !=0 ) { while ((p = _tcschr(p, _T('\0'))) && p != szDriveArray + nLen ) { if (GetDiskFreeSpaceEx(pStart, &free, &total, &totalfree)) // if success, nonzero { osConfig << "[" << pStart << "]" << " Total: " << std::fixed << /1024/1024/1024.0 << "GB Available: " << std::fixed << /1024/1024/1024.0 << "GB"; if (GetDriveType(pStart) == 3) osConfig <<" - Fixed Drive" << std::endl; else if (GetDriveType(pStart) == 4) osConfig <<" - (Remote Drive)" << std::endl; else osConfig <<" - Other" << std::endl; } pStart = ++p; } } else osConfig << "!Error: failed to get logical drive name." << std::endl; AfxMessageBox(().c_str()); //std::ostringstream file; //file << i << ".txt"; //std::ofstream log(().c_str()); //log << ().c_str(); //(); //(); //} AfxMessageBox("DONE"); }
Output information similar to the following:
