Re: "Named Event"

Yes, you can use OpenExisting to get a reference to an event that was created in a C++ program, for example, as long as they used the same underlying API (CreateEvent, CreateEventEx, which the managed wrappers use) with the same name.

As for DeviceIOControl, there is not a managed representation. You will have to call the function through the P/Invoke layer.

Aneesh,

As of .NET 2.0, you don't need to use interop to get the handle to named
events. You can call the static OpenExisting method to get a reference to
an event which already exists and is named.

Hello Nicholas,

thanks you and the other guys for your reply.

Can I use OpenExisting to sync with events set by app run from kernel
developed by C++?
Also, Is there a .NET way which replaces WIN API DeviceIoControl?

thanks.
