You're in the
c#
group:IOCTL and name events stuff
c#:
I need to write a GUI app which do the followings: 1. My app waits for events from other app(actually this is a network adapter driver) running in kernel. The driver writes to file and signal my app to read the file. 2. My app also need o communicate this the driver using IOCTL. Can i do it in C#? can C# wait for events signaled from app written in C\C++ app running in on kernel and sends messages to device using IOCTL? How complicated is it going to be? I'm quite noob in C# programming. should I consider duing it in C|C++ which I am quite noob as well? TIA,

If you are familiar with the API, maybe this post can help you: http://www.thescripts.com/forum/thread268027.html By the way, you can also post your question at microsoft.public.development.device.drivers newsgroup. Hope this helps. Cheers, Moty

Hi, True, but it worths to try :). Moty

I post it here because it's a C# specific question and I'm not sure if I get replys specific to C#.

Named events are placed in a global namespace (ignoring terminal services, but you can still access the global namespace even from there). [quoted text, click to view] > 2. My app also need o communicate this the driver using IOCTL. Yuck. IOCTL requires passing buffers around... C# may not be your best choice there.

The syntax is quite close to C# as far as interacting with the .NET framework, creating forms and buttons and so forth. But it also allows seamless access to the Windows API. At the very least, you should be able to reuse the header files provided by the kernel component, instead of having to transcribe everything into C# (constants, function prototypes, structure definitions, etc).

Correct me if I am wrong. deviceIoControl is function to communicate devices for IOCTL ? You think that it is best to use VC++ instead of C#? Also, when you mean that named event are in global name space what do you mean? shouldn't I import Kernel32.dll for that? thanks again.

In Visual Studio 2005, the C++ compiler can use both .NET and all Windows functions directly. That makes it really useful for communicating with drivers. You can still do your GUI in C# if you want, the functions you write in C++/CLI will show up in your C# program just like the .NET-provided ones.

Most of .NET simply calls a related function built into Windows. Here are the docs for the Windows function, CreateEvent: http://msdn2.microsoft.com/en-us/library/ms682396.aspx You might need OpenEvent instead: http://msdn2.microsoft.com/en-us/library/ms684305.aspx [quoted text, click to view] > > thanks again. >
