WMI services?

[john5632]

I am using WMI services to get drive info. I am able to get all except blocksize of drive. I am getting incorrect value. Code:

VariantClear(&vtProp);
hr = ptrclsObj->Get(L"BlockSize", 0, &vtProp, 0, 0);
INT BlockSize;
if ( FAILED(hr) == FALSE)
BlockSize = vtProp.intVal;;

Please guide.

What value, and what do you expect to be getting? What is ptrclsObj actually pointing at?
