I am developing my WiFi easy config module on Vista. I found Vista SDK
defines WLAN_CONNECTION_IGNORE_PRIVACY_BIT. In wlanapi.h, it is said that
this flag is for easy config association.

But when I use this flag in my code, it doesn't take effect. I create a
temporary profile with OPEN Authentication and NONE encryption. Then use
WlanConnect with this profile to connect to an WPA-AP. WlanConnect returns
SUCCESS, but I cannot capture any authentication request and association
request sent out.

Can anyone help on this issue? Is there any example on how to use this bit?

Here is my code:
pWriter->WriteStartDocument(XmlStandalone_Omit);

pWriter->WriteStartElement(NULL,L"WLANProfile",NULL);

pWriter->WriteAttributeString(L"p1",L"xmlns",NULL,L"http://www.microsoft.com/networking/WLAN/profile/v1");

ReadWriteXML_Name(TRUE,xmlToWlan,L"name",pWriter);
ReadWriteXML_SSID(TRUE,xmlToWlan,L"SSIDConfig",pWriter);

pWriter->WriteStartElement(NULL,L"connectionType",NULL);
pWriter->WriteString(L"ESS");

pWriter->WriteFullEndElement();

pWriter->WriteStartElement(NULL,L"connectionMode",NULL);
pWriter->WriteString(L"auto");
pWriter->WriteFullEndElement();

pWriter->WriteStartElement(NULL,L"MSM",NULL);
pWriter->WriteStartElement(NULL,L"security",NULL);

pWriter->WriteStartElement(NULL,L"authEncryption",NULL);

pWriter->WriteStartElement(NULL,L"authentication",NULL);
pWriter->WriteString(L"open");
pWriter->WriteFullEndElement();

pWriter->WriteStartElement(NULL,L"encryption",NULL);
pWriter->WriteString(L"none");
pWriter->WriteFullEndElement();

pWriter->WriteStartElement(NULL,L"useOneX",NULL);

pWriter->WriteFullEndElement(); //useOneX

pWriter->WriteFullEndElement(); //authEncryption

pWriter->WriteFullEndElement(); // security
pWriter->WriteFullEndElement(); // MSM
pWriter->WriteFullEndElement(); // wlanProfile
pWriter->WriteEndDocument();
pWriter->Flush();

// create a COM object to read the XML file
hr = CoCreateInstance(

);
if (hr != S_OK)
{

return dwError;
}
hr = pXmlDoc->load((CComVariant)TempStr, &vbSuccess);
if (hr != S_OK || vbSuccess != VARIANT_TRUE)

return dwError;
}

hr = pXmlDoc->get_xml(&bstrXml);
if (hr != S_OK)
{
dwError = ERROR_BAD_PROFILE;

}

I also meet the question at this time, when I try to use WlanConnect function to connect an AP(WEP),I failed. I know there must some wrong about the parameters what I set. It is probably the XML profile. But I reality don't know how to change it after I try anything what I can thing. Do you help me? Thanks very much, I will appreciate to it.
Looking forward to reply.

my code is as follow:


TCHAR xmlData[][33] = {
_T("Temp"),//_T("Profile Name"),
_T("PAN"),//_T("SSID"),
_T("ESS"),//_T("Connection Type"),
_T("auto"),//_T("Connection Mode"),
_T("open"),//_T("Authentication"),
_T("WEP"),//_T("Encryption"),
_T("false"),//_T("UseOnex")
_T("networkKey"),//_T("KeyType")
_T("1234567890"),//_t(KeyNum)
};

TCHAR xmlProfile[8192];
_stprintf_s( xmlProfile, _T("\

WlanConPara.wlanConnectionMode =wlan_connection_mode_temporary_profile;
