Re: WMI Methods in C++

Tech-Archive recommends: Fix windows errors by optimizing your registry

Well,

I have another problem, using SetDWORDValue method.

As I had :

// Create the values for the in parameters


varCommand.vt = VT_BSTR;
varCommand.bstrVal = L"toto";


// Store the value for the in parameters
hres = pClassInstance->Put(L"sValue", 0,
&varCommand, 0);

I'd like to set "lValue" of SetDWORDValue method to 0 or 1. But can't
find type of variant to set it ... I tried VT_UINT, VT_I8 and so
on ... but I got always same -2147217403 error ....


varCommand.vt = VT_UINT;
varCommand.uintVal = 1;


// Store the value for the in parameters
hres = pClassInstance->Put(L"lValue", 0,
&varCommand, 0);


Need some help again...

You have to set your impersonation level before you can make calls to
WMI. After you call:

hres = ppiWmiLoc->ConnectServer(bstrserv, NULL, NULL, 0, NULL, 0, 0, &pSvc)

You need to call:

hRes = CoSetProxyBlanket(pSvc, RPC_C_AUTHN_WINNT, RPC_C_AUTHZ_NONE,
NULL, RPC_C_AUTHN_LEVEL_CALL, RPC_C_IMP_LEVEL_IMPERSONATE, NULL, EOAC_NONE);

That should get you fixed up (I hope).

Later,
Chris

It says that : Either a required impersonation level was not provided,
