[Please advice]Failed to compile with CLSID_WbemLocator & IID_IWbemLocator

[ccc]

Hi,
[I searched around but I can't seem to find someone w/ the kind of
question I have, thus I am posting here for possible solutions, and I
think/hope it is a simple step that I am missing]

0) The following code failed to compile. I have installed the wmi sdk,
I don't know what is missing.

hr = CoCreateInstance(CLSID_WbemLocator, 0, CLSCTX_INPROC_SERVER,
IID_IWbemLocator, (LPVOID *) &pLocator);

It failed at CLSID_WbemLocator & IID_IWbemLocator = unknown
identifiers. This has been driving me nuts for more than a day, please
give me some pointers or steps.

1) Is WMI the ultimate solution to finding the driver date? If I can't
get the above to work, to access the date member, I need to find
another way, but I am clueless.

Thanks for any help.

#include <wbemcli.h>

add the library 'wbemuuid.lib' to the library you use to link your project

Thank you - that saved my day. I still would like to know if there is
another alternative way to extract driver file date from device
manager? The statement
fileVersion->dwFileDateLS
from
VS_FIXEDFILEINFO *fileVersion
always returns 0.

A different question from the above, is there a way to pop up a
pre-selected device property sheet from the device manager, i.e.
code-wise, to pop up the 'standard floppy controller' from the floppy
controllers under device manager w/o having to manually open device
manager?

Thank you very much.
