Quirk said; “accessing IO cards in realtime under windows XP”
Any type of realtime processing under windows XP is an oxymoron. Or as they say in the US state of Maine; “you can’t get there from here”.

In his original post, he's actually looking for 100 microseconds, or 0.1 milliseconds, so even this wouldn't work for him...

Oops! 
It was late last night [doing some marithon system testing] and I misread  the original post.
You are absolutely correct, this will not work for a timer interval of 100 microseconds as the minimum timeout resolution is 1ms and not guaranteed to precisely be even that.

Hello,
I'm coding a small Virtual Desktop Manager for our project needs.
I use Windows Station (WinSta0) and multiple Desktops. I create those
desktops with standard API (CreateDesktop). There is one problem that
I can't understand. How can I delete desktop that I have created by myself? I have tried CloseDesktop-function but it does not remove desktop.
So, how should I remove desktops that I create myself?
Any ideas?
Cheers!

You can't. Once a Desktop is created, you can't destroy it. The only way to get rid of it is to restart the machine!

But what actually happends if you can't delete Desktop and your PC's running Windows uptime is
long and you create lot's of Desktop because of your needes? Is it so, that when resources are finished your PC running Windows crashes?
This sounds wierd.
Is it possible to create own Window Station and inside it Desktops and then delete
Window Station?
Cheers!

If you try to create a Desktop with the same name, you'll get a handle to the existing Desktop of that name. Windows won't create a new one. There's a reason why you don't see applications creating their own desktops...

Hi, in windows explorer we could know the size of file or the size of folder which containt the file. Does any one know about the size of an empty folder that just created?
|
|
|
|
|
if the folder contains no file, then it weights 0 bytes...
same for files with nothing in them, they weight 0 bytes...
(of course, their reference are stored somewhere the user can't access directly on the hard disk...)

I agree with notepad file. But for microsoft word file, when you create a blank documetn and save it without type anything or add any thing to the document you will get your file size is 11kb. Try to test it in your machine.

What does reference mean in here?

i never talked about "empty docs", i talked about "empty files", which is largely different !
save an empty word doc and open it with notepad !!!!
what to you see? hyeroglyphs ?
perfectly normal. Word isn't a plain text editor...

The information that says there's a file called XXX in location YYY on the partition. You can't access this without kernel level code, and unless you're building a defrag type tool you'll never need to.

Can you explain or find any resource more deeply about kernel level code?
|

It's the lowest level of interal OS code, and is where the core segments of the OS operate. I've never done any programming in it, and you need to use unmanaged code (c/c++) to access it. Sorry I can't be of more help.

On an old DOS FAT12, FAT16, or FAT32 volume, this is called the File Allocation Table. On an NTFS volume, it's called the MFT, or Master File Table. It's an index of all the files and folders stored in the volume and where they exist on the drive.

Can we preview an index table?

I mean can we preview an index number of each file in any application or the command prompt?

You're still not making any sense...
Again, what do you mean "preview"??? There's nothing to "preview" or see in FAT or MFT. Theses are data structures stored on the disk. You can't get to them using any file operations.

That answer is enough to my question.

Hi, in windows explorer when we explore in an empty folder that just create we didn't find any thing. But if we use the DIR command in the command prompt it will display as the below:
Volume in drive C has no label.
Volume Serial Number is 1E68-CB16
Directory of C:\tes

08-Feb-2006 05:21 PM 0 emp.txt
1 File(s) 0 bytes
2 Dir(s) 65,743,151,104 bytes free
Can any one tell where does these:
