如何在c +++中调用wmi提供程序中的两个类 [英] how to call two class in wmi provider in c+++

问题描述

我已经创建了wmi提供商。

工作正常。

i有两个名称为



cObject1，cObject2。





这是我的dll的条目，如果我为cObject1创建对象，那么cObject1 funcaiton正在调用

那时我需要单独查询cObject1对象。



如果想同时调用这两个类意味着wmi查询，如果我做了cObject2，它也想要查询自己的函数并需要返回值。

I have create the wmi provider .
Its working fine.
i have two classes in that name as

cObject1, cObject2.


This is entry of my dll, if i create the object for cObject1 then cObject1 funcaiton are calling
That time i need to query the cObject1 object alone.

if want to call both the class at same time means wmi query if i did cObject2 also it suppose to query its own funcation and need to return the value.

STDAPI DllGetClassObject(REFCLSID rclsid, REFIID riid, LPVOID* ppv)
{

}

对于这两个课程，我使用单个GUID

如何实现这一目标。

For both class i am using single GUID
how to achieve that.

推荐答案

您不能对两个不同的类使用相同的GUID。系统如何确定您指的是哪一个？请参阅 COM简介 - 它是什么以及如何使用它。 [ ^ ]。

You cannot use the same GUID for two different classes. How is the system expected to determine which one you are referring to? See Introduction to COM - What It Is and How to Use It.[^] for a useful article on COM.
