Thanks Michiel - it worked just fine.
Just in case anyone else wants to know, here's the source for reading out
the current signal strength on the last wireless lan adapter installed (in
case you have more than 1). Anyway, the source can be easily changed.
int GetSignalStrength()
{
ManagementObjectSearcher *searcher = new ManagementObjectSearcher(
"root\\WMI",
"select Ndis80211ReceivedSignalStrength from
MSNdis_80211_ReceivedSignalStrength where active=true");
ManagementObjectCollection *queryCollection = searcher->Get();
ManagementObjectCollection::ManagementObjectEnumerator* queryEnum =
queryCollection->GetEnumerator();
while (queryEnum->MoveNext());
ManagementBaseObject* object = queryEnum->get_Current();
Object* signalStrength =
object->GetPropertyValue(L"Ndis80211ReceivedSignalStrength");
return (Convert::ToInt32(signalStrength->ToString()));
}
Best regards
