Well, my first reaction is, "You're screwed.", but maybe that's not the case
in your specific situation.
Some wireless cards, when they are configured for using a specific
configuration program, rather than WZC, stop looking like wireless cards at
all to Windows CE. If that's the case, I think you're screwed unless you
know something about how the card is reconfigured to make that happen. It
would probably be a registry setting on the card's driver, but it might
easily be different for every card.
The other way to disable WZC is to uncheck the checkbox in the network
settings that says something like "Use Windows to configure my wireless
settings." When that is unchecked,
a setting is made in the registry. I don't have a device at my current
location that I can use to find that, but you could easily export the
registry using Remote Registry Editor with the setting checked and then
again after unchecking it and difference the two files to find the setting.
If that's how the state is being changed, which is more likely than not,
then all you'd need to do is make the suitable registry change, then rebind
the adapter (you know how to do that, right?), causing it to reconnect to
the network using the latest registry settings. I think that should do it.

My target device is having a 3rd party XXXX Security manager (same as
microsoft WZC).
At a time one will be enable either XXXX or WZC...
So before my app run to configure SSID, I need to enable WZC (if it's
disabled ...)
How can I check whether WZC is enabled or not, if its not How can I
enable it ??
Thanks a lot ..

NO. I seriously doubt that anyone is going to figure this out for you. How
is your target access point configured? What authentication and encryption
options does it require? You're sure that it's completely open? No MAC
address filtering? I'm afraid that I'm not up to reading your code looking
for a byte out of place. Do you have the source code for Windows CE? You
could compare what you're doing to what WZC itself actually does when you
click Connect in the WZC dialog. If it were me, that's what I would do. I
suppose that, if you want another tangent to run with, you could get
OpenNETCF's Smart Device Framework, in which there is a set of classes and
I
and others have written for WZC control, and see if it will connect you
(and
if so, read the source and figure out what you're doing wrong).
What do you mean by enable/disable WZC? For what purpose would you want to
do that?

1). I tried to do it with the help of WZC. below is the complete code.
but
when I run this code, it dissociate the current SSID, but don't set the
newly
given SSID. Can anybody please figure out the problem here .
//********************
DWORD dwInFlags = 0;
//Set SSID in ssid struct
NDIS_802_11_SSID ssid;
TCHAR* pSSId=_T("ASSET");
ULONG lSSIdLength = _tcslen(pSSId);
ssid.SsidLength = lSSIdLength;
wcstombs( (char*)ssid.Ssid , pSSId, lSSIdLength );
RAW_DATA RawData;
RawData.pData = (LPBYTE)&ssid;
INTF_ENTRY *Intf = new INTF_ENTRY();
Intf->wszGuid = _T("PRISMA021");//(LPWSTR)pAdapter->AdapterName;
Intf->rdSSID = RawData;
DWORD dwOutFlags;
uint uret = WZCQueryInterface(NULL, INTF_ALL, Intf, &dwOutFlags);
if ( uret == ERROR_SUCCESS )
{
WZC_WLAN_CONFIG *thisConfig = new WZC_WLAN_CONFIG();
thisConfig->KeyLength = 0;
thisConfig->AuthenticationMode = Ndis802_11AuthModeOpen;
// If we have no key, we should probably set this to WEP Off.
thisConfig->Privacy = Ndis802_11WEPDisabled;
thisConfig->InfrastructureMode = Ndis802_11Infrastructure;
DWORD result = WZCSetInterface(NULL, INTF_PREFLIST, Intf, &dwInFlags);
if(ERROR_SUCCESS != result)
{
CString pp;
pp.Format(_T("WZCSetInterface() failed: %d"), GetLastError());
AfxMessageBox(pp);
}
else
AfxMessageBox(_T("Done"));
delete(thisConfig);
}
else
AfxMessageBox(_T("WZCQueryInterface failed"));
delete(Intf);
//*************************
2). Another Question that how can I enable/disable the WZC from my
application? I got some blogs saying "Use "DeactivateDevice" function.
The
handle of WZC you can get from
registry into HKLM\Driver\Active\XX\Hnd" but it dint work as:
HANDLE rtn = ActivateDevice(_T("4970496"), 0);
Is there any other way to enable/disable WZC???

2. and *is* it an open access point? They're pretty hard to find any
more.
WZC is the right way to attach to a new network. There have been
previous
posts in various Windows CE newsgroups on this topic. You can search
microsoft.public.windowsce.* using GoogleGroups advanced search:

Hi all,
Currently I am working on a WM5/PPC 2003/WinCE5 device based
application
in
which I am using NDISUIO driver to set the SSID. I am able to scan
the
SSID
list as well as Disassociate to currently associated SSID.
But I am not able to associate to SSID. It's returning always true
but
not
setting the SSID. Below is the code.
Way 1: This is the first way I tried.
HANDLE hDevice = CreateFile(NDISUIO_DEVICE_NAME, GENERIC_READ,
FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL | FILE_FLAG_OVERLAPPED, NULL);
LPCTSTR pszSsid = L"Dev";//SSID
BYTE pBuffer[sizeof(NDISUIO_SET_OID) + sizeof(NDIS_802_11_SSID)];
PNDISUIO_SET_OID pNDISUIOSetOid = (PNDISUIO_SET_OID) pBuffer;
PNDIS_802_11_SSID pSsid = (PNDIS_802_11_SSID) pNDISUIOSetOid->Data;
pNDISUIOSetOid->ptcDeviceName = (PTCHAR) pszAdapter;
pNDISUIOSetOid->Oid = OID_802_11_SSID;
CTtoA ssid(pszSsid);
pSsid->SsidLength = min(ssid.GetLength(), sizeof(pSsid->Ssid));
memset(pSsid->Ssid, 0, sizeof(pSsid->Ssid));
memcpy(pSsid->Ssid, (LPCSTR) ssid, pSsid->SsidLength);
// DWORD dwBytesReturned = 0;
if (!DeviceIoControl(
hDevice, IOCTL_NDISUIO_SET_OID_VALUE,
pBuffer, sizeof(pBuffer),
NULL, 0,
&dwBytesReturned, NULL))
{
DWORD dwError = GetLastError();
printf("FAILED\n");
printf(" Function \"DeviceIoControl\" failed (0x%08x).\n",
dwError);
return FALSE;
}
Way 2: I got another way to do the same .
http://geekswithblogs.net/dastblog/archive/2006/12/23/101954.aspx
(please look into this option too.)
But also this way SSID couldn't be changed.
A. Can anybody tell me where I am lacking in Way 1 and Way 2?
B. Is there another way to set SSID?
C. Which one is the preferred way to do this task, using NDIS or
using
WZC?
Please let me know if U knows something ..
