i have put condition like when it found adhoc it should connect with that
my friend has created adhoc with no authentication and when i am running this code it is giving me error like invalid parameter so please help me out..
first of all i am scanning all available network which give result in pAvailableNetworkList object which is i am accessing over here..

if(pAvailableNetworkList->Network[i].dot11BssType==2)
{
 cout<<"\nProcess to Connect to adhoc";
 WLAN_CONNECTION_PARAMETERS ConnPara;
 ConnPara.wlanConnectionMode = wlan_connection_mode_discovery_unsecure;
 ConnPara.strProfile = NULL;
 
 DOT11_SSID temp2;
temp2.uSSIDLength = pAvailableNetworkList->Network             [i].dot11Ssid.uSSIDLength;
temp2.ucSSID[temp2.uSSIDLength] = pAvailableNetworkList->Network [i].dot11Ssid.ucSSID[temp2.uSSIDLength];
			
 ConnPara.pDot11Ssid = &temp2;
 ConnPara.pDesiredBssidList =NULL;
 ConnPara.dot11BssType = dot11_BSS_type_any;
 ConnPara.dwFlags = WLAN_CONNECTION_ADHOC_JOIN_ONLY;
 DWORD temp =WlanConnect(
                  hClientHandle,
		  &interfaceGuid,
		  &ConnPara,
		  NULL
			);
if(temp == ERROR_SUCCESS)
  cout<<"\nSuccess";
if(temp == ERROR_INVALID_PARAMETER)
  cout<<"\nERROR INVALID PARAMETER";  ///I am getting this error
