Enable network adapter and BindAdapter exceptions.

[BLUE]

Enable and Disable in the Network and DialUp Connections manager is actually
setting a bit in the registry for the target adapter and then calling NDIS
to unbind or bind (depending on whether your disabling or enabling the
adapter).
In HKEY_LOCAL_MACHINE\Comm\NdisPower insert this value to disable the
adapter:
<adapterNameREG_DWORD 4 (0x00000004)

Delete the value to enable the adapter
To do a NDIS bind or NDIS unbind you can use these API:

VOID NdisBindProtocolsToAdapter
(
PNDIS_STATUS pStatus,
PWSTR wszAdapterInstanceName,
PWSTR wszProtocolName
);

VOID NdisMRebindProtocolsToAdapter(NDIS_HANDLE MiniportAdapterHandle);

VOID NdisUnbindProtocolsFromAdapter
(
PNDIS_STATUS pStatus,
PWSTR wszAdapterInstanceName,
PWSTR wszProtocolName,
);
I've tried using these API but I get a NotSupportedException
So I've tried using OpenNetCF.Net Adapter class but:

- I do not understand why I get an exception on the first time I try to
bind or unbind
- I do not know how to bind the adapter if it is disabled: the only way is
modifying Adapter source code so that the Name property let me set the Name:
exploring the source I've found that Adapter class needs only the name to
call internal bind functions

using OpenNETCF.Win32;
using OpenNETCF.Net;
[DllImport("Ndis.dll", SetLastError = true)]
private static extern void NdisBindProtocolsToAdapter
(
ref int pStatus,
ref string wszAdapterInstanceName,
ref string wszProtocolName
);

[DllImport("Ndis.dll", SetLastError = true)]
private static extern void NdisUnbindProtocolsFromAdapter
(
ref int pStatus,
ref string wszAdapterInstanceName,
ref string wszProtocolName
);

// THIS CAN BE DONE ONLY IF DISCOVERY WAS MADE WITH ADAPTER ACTIVE
