help needed on WlanGetAvailableNetworkList''s attribute
int ScanAPs()
{
cout << "<- In ScanAPs() Function ->" << "\n";
PDOT11_SSID pDot11Ssid = NULL;
WlanScan(phClientHandle, &ppInterfaceList->InterfaceInfo[0].InterfaceGuid, NULL, NULL, NULL );
PWLAN_AVAILABLE_NETWORK_LIST pNetworkList = NULL;
WlanGetAvailableNetworkList(phClientHandle, &ppInterfaceList->InterfaceInfo[ 0 ].InterfaceGuid, 0, NULL, &pNetworkList);
cout << " Num of Networks : " << pNetworkList->dwNumberOfItems << "\n";
cout << " 0 : " << pNetworkList->Network[0].dot11Ssid.ucSSID << "\n";
cout << " 1 : " << pNetworkList->Network[1].dot11Ssid.ucSSID << "\n";

return (0);
}
i got a scan for 4 wireless network in the " Num of Networks : 4"... but i only can get the essid for the 1st array that is " pNetworkList->Network[0].dot11Ssid.ucSSID ", and i cannot get any information for the second array information that is " pNetworkList->Network[1].dot11Ssid.ucSSID " ... can someone pls help me ?
Thanks in Advance ....

hi i have sample which is working fine but code is in c#

hope this is helpfull to you...
hey , thanks for the fast reply ...
i use the coding and methology that u provided but i still can manage to get the problem solved ...
isit the problem cause by the operating system platfrom that i use ? i am currently developing the program at Windows home
edition Service pack 2 ...
looking forward for rely ,,,, thanks iin advance ...
