C++ WMI获取系统硬件信息(CPU/DISK/NetWork etc)
官网找到一个例子，根据例子修改下可以获取很多信息
#define _WIN32_DCOM #include <iostream> using namespace std; #include <comdef.h> #include <Wbemidl.h> #pragma comment(lib, "wbemuuid.lib") int main(int argc, char **argv) { HRESULT hres; // Step 1: -------------------------------------------------- // Initialize COM. ------------------------------------------ hres = CoInitializeEx(0, COINIT_MULTITHREADED); if (FAILED(hres)) { cout << "Failed to initialize COM library.

MSDN官网关于WMI的demo程序
PS:过两天我会把我修改的程序传上来，实现了 CPU编号、序列号、型号； 硬盘序列号；网卡MAC地址、IP地址、当前状态，这些信息的获取。
