问题描述

以下是我使用的代码，但总是失败，错误0x8004101e（wbemErrIllegalOperation引用 WbemErrorEnum（Windows） [ ^ ]）致电

the following is the code I used, but alway failed with error 0x8004101e(wbemErrIllegalOperation reference here WbemErrorEnum (Windows)[^]) when call 

hr = pclsObj->GetMethod(bstrMethod, 0, &pInParamsDefinition, &pOutParamsDefinition);





，我真的不知道为什么，任何建议都表示赞赏。提前谢谢。





,I really don't know why, any suggestions is appreciated. thanks in advance.

这里是调用Format使用WMI的正确方法。参考网站如下。

here is the right way to call Format use WMI. reference websites are as follow.
