Win32_NetworkAdapterConfiguration EnableDHCP method problem

[z160896]

This is the section code:

BSTR MethodName = SysAllocString(L"EnableDHCP");
// BSTR MethodName = SysAllocString(L"EnableStatic");
IWbemClassObject * pInClass = NULL;
IWbemClassObject * pInInst = NULL;
IWbemClassObject * pOutInst = NULL;
IWbemClassObject * pvClass = NULL;

VARIANT pathVar;
hres = pSvc->GetObject(L"Win32_NetworkAdapterConfiguration", 0, NULL, &pvClass, NULL);

if( hres != WBEM_S_NO_ERROR )
{
plogfile->WriteError(_T("Network: Failed to query Win32_NetworkAdapterConfiguration, error code: %x\r\n"), hres);
SysFreeString(MethodName);
return hres;
}


hres = pvClass->GetMethod(MethodName, 0, &pInClass, NULL);
if( hres != WBEM_S_NO_ERROR )
{
plogfile->WriteError(_T("Network: Failed to EnableDHCP method, error code: %x\r\n"), hres);
SysFreeString(MethodName);
return hres;
}

If the method name is EnableStatic, pInClass is valid pointer. Any methods related to DHCP for exampe, ReleaseDHCPLease, will return with pInClass as NULL. Other methods return with pInClass as valid pointer.

Anything I did wrong?

This issue is solved: As EnableDHCP doesn't require parameter inputs, pvClass->GetMethod(MethodName, 0, &pInClass, NULL); returns with NULL pointer for pInClass.
