获取主板系列号
来源:互联网 发布:深度linux u盘安装 编辑:程序博客网 时间:2024/05/18 00:37
从microsoft msdn摘下来的代码, 改了一点, 读取主板系列号.
原代码出处: http://msdn.microsoft.com/en-us/library/aa390423(VS.85).aspx
为获取主板系列号, 修改了两条语句,见代码注释
另外, 这段程序读取的系列号与用工具 everest v3.50.865 Beta 获取的主板ID 不一致, 不知为何?

// Note: If you are using Windows 2000, you need to specify -
// the default authentication credentials for a user by using
// a SOLE_AUTHENTICATION_LIST structure in the pAuthList ----
// parameter of CoInitializeSecurity ------------------------

// For example, get the name of the operating system
IEnumWbemClassObject* pEnumerator = NULL;
hres = pSvc->ExecQuery(
bstr_t("WQL"),

// Step 7: -------------------------------------------------
// Get the data from the query in step 6 -------------------
