Didn't realize there was a link on "Semaphore" in your first msg. My fault.

I would like to force DataGrid to use my implementation of IComparer when sorting columns.
Can anyone give me some ideas on how to achieve that if possible at all??

String.Compare is used internally by the DataView.Sort property (in the set accessor) with no way to override it.

Out of curiosity, could you derive a class from DataView (dunno if it's sealed or not, too lazy to open up studio right now) and override the Sort property?

It's not virtual, so you'd have to hide it, but the controls like the DataGrid will indirectly refer to your type as a DataView, meaning that its definition of Sort would be used.

Ah bugger...you could always decompile System.Data.dll, modify the IL, then recompile it

Install it, configure it in VS.NET's Tools-<Options, then add your projects to source control by right-clicking and selecting Add to Source Control (or from the File-<Source Control) menu. Note, with VSS 6.0 you can either add a solution (not a good idea in most large development projects where developers may want their own solutions with whatever projects they're responsible for) or a single project - you cannot add multiple projects without problems.
From there, you just check out your files, edit them, test them, then check them back in. Never check-in incomplete code (i.e., that won't compile), otherwise you'll cause problems for anyone else.
The best way to learn is to just try it and check out all the options available. It's really not difficult and there's really not a lot of articles that explain the simple stuff - more so just how to managed certain types of projects like ASP.NET sites, which can be a hastle because of their nature. For those types of articles, just see http://msdn.microsoft.com[^].

Quick Question : How is remote debug setup?
Sounds simple enough, but there are a few hurdles in the way :
1) I dont have physical access to the machine that will be debugged
2) I cannot install Visual Studio on it, nor run the VS install and just select remote debug tools.
3) The machine I am debugging from is in a standard windows domain, the machine i am debugging to is in a DMZ and cannot see domain logon details - therefore I cannot add myself as a "Debugger Users"
4) I have tried running the debug server with "-anyuser" in "-tcpip" mode but VS still tells me I cannot connect as I need to be part of the "Debugger Users" group
So in summary I need to configure/install remote debugging by transferring the necessary files across the network and then running it in such a way that I am prompted for a user/pass when connecting to the remote debug services or allowing remote debug for any connecting user.
I have followed the instructions located at :
http://msdn.microsoft.com/library/en-us/vsdebug/html/vctskInstallingRemoteDebugMonitor.asp[^]
But this just presents me with :
Visual C++ Remote Debug Monitor(x86) Version 7.10.3077
But I need to be able to debug J#, VB .NET, C#
Any help is greatly appreciated

Without physical access or security rights on the remote machine, you're pretty much sunk. You may need to bring IT in on this one, if you can pull them away from all their important work...you know, solitaire, civ, playing XBox in the back room, that sort of stuff.
Once you get install the remote debugging tools, you're pretty much set and you obviously know what you're doing from there.

If you can't install the debugger tools how do you debug it? Remote Debugger is not a way to work around the lack of debugging tools but a tool to use in special cases and this doesn't sound like its applicable.
You are pretty much stuck without a little help from IT. Remote Deubgging is very iffy when crossing sub-net boundries in the first place let alone a machine sitting in a DMZ (connections between the DMZ and trusted nets should be limited by any sane IT admin). Then there is the question of how domains are configured going between the trusted net and the DMZ. They very well maybe completely seperate domains which adds a wrinkle. Besides, installing the Remote Debugger on a production machine might be a security hazard that maintainers don't want to deal with.
The best thing I can recommend is setting up another machine that closely approximates the machine/system in question. Simply put it might be impossible to get the Remote Debugger to work out of a machine in the DMZ because of security policies in place. Without further input from your IT staff who knows what is going wrong. Hopefully you aren't tinkering with live machines in the first place!

Web or Win Form?
There are some events and properties in WinForm to see keyboard: KeyPreview, KeyPress, KeyDown etc. See EventArgs and KeyData, KeyChar, KeyCode properties.

There's many ways of doing this. If you want to catch these in your derivative class, override OnKeyDown. External to your class, handle the KeyDown event. This is to catch and potentially "handle" the key without it being passed to the target window. If you don't care about stopping it from being dispatched, you can handle either KeyPress or KeyUp.
In there, you actually use the KeyEventArgs - not the EventArgs like the other response mentioned - to get the Keys enumeration member for pressed keys, or just the ASCII character value itself. See the documentation for the KeyEventArgs members for more details.
If you want to catch keys throughout your application (say, for configurable hot keys), implement the IMessageFilter class and add your implementing using Application.AddMessageFilter. You get a Message structure that contains the message (such as WM_KEYDOWN) and you can get the data from the WParam and LParam properties. You can also return true to signal that you've handled it and the message should not be dispatched.

C# doesn't use header files. You'll have to rewrite the C++ constants, structures, function headers, whatever your trying to use in the header file, into C# code.

I want to use a variable (or constant) in following class property:
[EventTrackingEnabled(true),ObjectPooling(true,1,50)]
public class Aktualizacje : ServicedComponent
{...
instead of number 50 in many classes in many projects of one solution. Is it possible? Thx in adv

You can declare constants and use those in your attributes, but not variables. Since attributes are metadata, the values must be defined at compile-time, not at runtime.

Just overload the constructor, very handy with attributes. Remember attributes are readonly because they are stored in metadata, and hence, can be changed at runtime.

He said he didn't want to call that and exit the whole application.
