Device Drivers and Application Programs

OK, I know this probably isn't the right forum but since I can't figure out where I should pose my question I'll pose it here.
Can a device driver be written so that, when it gets called by some application, the device driver can know what application is calling it?

Write a proxy in between the application and the device driver.

This is a device that will be used by anybody. There will not be any specific application program of my own that will be associated with it. But it will need some way of knowing what applications are indeed accessing it, so that it can respond in specific ways based on what application is accessing it. Basically I want the user to be able to specify which applications can access it, and fo rthe device driver (or SOMETHING) be provided with that list of "valid" applications, then the dvice driver, by knowing what application happens to be trying to access it at any given time, can respond by either allowing the access or denying the access.
So, it there a way that this can be done? Can a device driver figure out what application happens to be accessing it?

There's not a good forum for this, but they should tell you before they turn you away that you can't do this in C# right now, but you can in C++.
Other forums you can ask in...
Visual C++ (categories)Now here is some of my searching around...
http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/8e4c0a4d-e0b1-4bdf-89c9-a4574a020f1a - How to write a device driver (ironically this is the forum your question was moved out of)
In that thread, Giorgi says: "You will need Windows Driver Development Kit in order to write drivers. You can write them in c++ but not in c#."

Ed,
This is all great information, but what I really need is an answer to my very basic question (BEFORE I try to wade through all the instructions on HOW to write a driver).
Can the device driver itself know what program is calling it? For example, if I've written a device driver for a Disk Drive and installed it on someone's computer and subsequently some program (ANY program) tries to make access to a file on that disk drive, or even ifthe applicationt causes the standard file select dialog to come up, providing access to my disk drive, can the device driver itself KNOW what application is is making use of it? Can the device driver KNOW the name of the application or perhaps KNOW the location of the application (i.e. what folder it resides in) or SOMEHOW identify what application is calling it?

You need a user mode component for the driver. I am not sure you can write a user mode component for a disk drive though, I only know some graphics card use it to isolate the address overhead to the process space. Visit the WDK forum and ask if it is possible to have a user mode component for a disk drive.

Roger, I know. This isn't an answer forum though. This is a "I don't know where to go. Can someone tell me where to ask my question?" forum. So that's what we deliver here... Places to go ask your question. I'll see where the WDK forum is.

Visual C++ MVPSpecifically it looks like the WDK issues are handled in the Windows SDK forum here:
http://social.msdn.microsoft.com/Forums/en-US/windowssdk/threads
And here's the MSDN page to learn more about the WDK:
