Accessing ActiveX Methods from MMC Snap-in

[macgowan]

Hi ...

I have a ActiveX Control and I'm using it in a MMC Snap-in. This is my first time. I have some sample code that shows how to access the properties from the snap-in. I have shown this code below.

    switch (event)
    {

    case MMCN_INITOCX:
        {
            // Use ATLs IDispatch helper class to access ActiveX Properties
            CComDispatchDriver spStatus = LPUNKNOWN(param);

            // Set the TestValue value in ActiveX Control
            spStatus.PutPropertyByName(L"TestValue", &CComVariant(7));
        }
        break;
    }

So ... I have a method in the ActiveX Control and would like to execute it ... For example the About box or the PropertySheet or in my case a simple method called Beep() that will make a sound.

Thanks,
Chris

He again ...

I have tryed this and it does not seem to all the method ???
I will try to look further.

            HRESULT hresult;
            IDispatch FAR* pdisp = (IDispatch FAR*)NULL;
            DISPID dispid;
            OLECHAR FAR* szMember = L"BeepSound2";

            hresult = spStatus.p->GetIDsOfNames(IID_NULL,
                                           &szMember,
                                           1, 
                                           LOCALE_SYSTEM_DEFAULT,
                                           &dispid);

            spStatus.p->Invoke(dispid, 
                               IID_NULL, 
                               LOCALE_USER_DEFAULT, 
                               DISPATCH_METHOD, 
                               NULL,
                               NULL, 
                               NULL, 
                               NULL);

Thanks,
Chris
