Is it possible in C# app to react on some "USB device connected" event (USB Mass Storage, to be more precise) and obtain its new drive letter?
I have a directory tree and want to refresh it when new drive appears (e.g. flash disc).

You should start using unmanaged code then, kernel32.dll I think. You could also use user32.dll to read system messages. Search http://www.pinvoke.net for sample code.

since it's a "mass storage device" microsoft has a generic driver for it... that's all I know.

Cbeck out some article on Coding4Fun on MSDN. That should tell you how to do it.

I have several classes that make a namespace 'CsGL.Basecode'. In my application i would like to use them (by writing 'using System.CsGL.Basecode'). How to add this namespace into that project easily? Do these classes have to be copied into appropriate folder?
thank you very much for any help

You have to include them in the refernce file.

What is exactly this file name? And did you mean that i have to add them 'manually' or in visual studio?

In the sollution explorer there should be a reference 'folder' where you can add it. The 'folder' is actualy a file that you can change manualy.
I got Microsoft Visual Studio 2005 Beta 2, I don't know how your VS look like but it should be the same.

There is no way to add a reference via VS (I have VS2003 but as you said, that shouldn`t make any difference), because he accepts only 'component files' (and I want to add a namespace which consist of several classes).
In the 'C# project file' there are 2 possibilities where I could add it:
<Reference
Name = "System.XML"
AssemblyName = "System.XML"
HintPath = "..\..\..\..\..\WINDOWS\Microsoft.NET\Framework\v1.1.4322\System.XML.dll"
/>
<File
RelPath = "App.ico"
BuildAction = "Content"
/>
I tried with the reference but still in main class this was not possible to write using System.CsGL.BaseCode

You could include the source files in the sollution or you could make a class library wich produces a dll that you could include.
When I said to include a namespace I though you allready got it in a dll...

You can compile the classes into an assembly (.dll) by creating a new "Class library" project and copy all .cs files into that project. Then you can reference that assembly in every project where you need the classes.

What do you mean by that? Have all classes just the same namespace or do you also compile them to a library?
If these classes are available as source files then simply add them to your project by right-clicking on the project folder and selecting "Add existing item..". If they are compiled to a library, you have to reference this library as said by the other poster.
Anyway, if the classes are declared in the namespace "CsGL.Basecode" you cannot access them via "System.CsGL.Basecode", cause your namespace won't be added to the System namespace.

how i can use assembly rouitines in C#
like in Visual C++ that we can use assembly routines by typing
asm
{
//... assembly routines
}

There is no inline assembler in C#. C# compiles to MSIL, not assembly language. The IL code is compiled on-the-fly into processor-specific machine code at runtime. There is no way to put asm code into a C# source file and actually have it compile.
The only way around this is to write your asm code into a Managed C++ module, then call these functions from C#.

Um, why are you even running reg? You can probably do what you need directly...

I want to read some remote registry key , I know about OpenRemoteBaseKey but I think its easier for me to get all the result with reg.exe. and also as in MSDN for OpenRemoteBaseKey:
In order for a key to be opened remotely, both machines (the service, and client) must be running the remote registry service, and have remote administration enabled.
But reg.exe at least do not need the client to have this service started , as I tested.

Did you try WMI? It is pretty easy to set up interop stuff to use WMI.

Yah , But didn't find a way to query registry with WMI locally or remotelly. Do you know a way? Anyway , thanks for your reply.

I think what your looking for is the ProcessStartInfo.CreateNoWindow property. Just set it to false.
