How to control a NDIS device via NDISUIO driver

Dear all,

I want to control a NDIS device via NDISUIO drvier.
Also, I want to use NDISUIO driver to write and read data.

Now, I can create the handle for the device.
When I want to bind the handler to the adapter,
it occur error.

PS1: My WLAN card is CISCO Aironet 350, My OS is WinCE.NET 4.2
PS2: My code is as following.

-Kemin
----------------------------------------------------------------------
BOOL UnReBindAdapter( int nBindType, PVOID pAdapter, DWORD dwAdapterLen,
PVOID pProtocol, DWORD dwProtocolLen )
{
CHAR Buf[512];
HANDLE hPhysicalDevice;
DWORD bResult,dwReturnedBytes;

memset( Buf, 0, 512 );
memcpy( Buf, pAdapter, dwAdapterLen );
memcpy( Buf+dwAdapterLen, pProtocol, dwProtocolLen );

hPhysicalDevice = CreateFile( _T("NDS1:"), GENERIC_READ|GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL | FILE_FLAG_OVERLAPPED,
INVALID_HANDLE_VALUE);

if( INVALID_HANDLE_VALUE == hPhysicalDevice )
{
CommEvent::PrintEvent( "INVALID_HANDLE_VALUE\n" );
return bResult;
}

bResult = DeviceIoControl(
hPhysicalDevice,

(nBindType==BIND ? (IOCTL_NDIS_BIND_ADAPTER) :
(nBindType==UNBIND ? (IOCTL_NDIS_UNBIND_ADAPTER) :
(IOCTL_NDIS_REBIND_ADAPTER) ) ),

Buf,
512,
NULL,
0,
&dwReturnedBytes,
NULL);

CloseHandle(hPhysicalDevice);

return bResult;
}

So what's the problem? Your code seems roughly correct for binding and
unbinding an adapter, although I didn't try to compile and run it. Why
would you want to read and write data directly to the device?

Dear Paul,

Thanks for your reply.

I've solved the problem by disabling some services on WinCE 4.2.

Because I want to implement a special WLAN authentication
protocol(EAP-SIM)
that is not supported on WinCE 4.2 now.
So I have to make my own ethernet frame and send it the the device.
That's the reason why I want to read and write data directly to the
device.
