WMI failed to initialize the IWbemLocator using CoCreateInstance(CLSID_WbemLocator, 0, CLSCTX_INPROC_SERVER, IID_IWebLocator, (LPVOID *) &pLoc); It always return failure

Question

Hi All,

I am using WMI to get SMBIOS data and for that I am using following code to initialize the IWbemLocator interface through a call to CoCreateInstance.

CoCreateInstance(CLSID_WbemLocator, 0, CLSCTX_INPROC_SERVER, IID_IWebLocator, (LPVOID *) &pLoc);

But it always returns FAILURE. I think its due to some environment issue but wanted to know exact reason.

Thanks in advance,

Rahul

Answer 1

IID_IWebLocator? What's that? What is the HRESULT you get? Sample code is here, also note the CoInitializeSecurity() call.
