Hi guys,

I'm having a hard time to subscribe to a native event in C#.NET. The
application I'm writing should be able to detect changes in DHCP
parameters. This is done through the following:

DWORD APIENTRY DhcpRegisterParamChange(
DWORD Flags,
LPVOID Reserved,
LPWSTR AdapterName,
LPDHCPCAPI_CLASSID pClassId,
DHCPCAPI_PARAMS_ARRAY Params,
LPVOID Handle
);

How do I tackle this? Do I have to use CreateEvent from kernel32.dll to
subscribe to this event? And how do I consume this event from managed
code (i.e. C#.NET)?

Thanks in advance,

Benny

From the usage examples at
http://msdn.microsoft.com/library/en-us/dhcp/dhcp/dhcp_client_api_examples.asp
it seems like you don't have to create the event object yourself,
rather it's returned by the API.

You can use the Wait APIs manually (like the sample code) or wrap it
in a managed WaitHandle.
