Your welcome.
But I missed a couple of (minor) details:
1.
The argument OPEN_ALWAYS should of course be OPEN_EXISTING.
2.
The comment "// Read the sector, 512 bytes", should have been
"// Read 12 bytes "
The eternal "cut and paste" syndrom. 
Kakan.
BTW, you know you can give points to a response that helped you with your problem?

Please help me...
Is there anyone know how to take this kind of program into practice in general:it is been started just after booting,for the user who is not the administrator.And when the program is running,the user can only do things that the program permit and can't do anything that the program doesn't permit,including exiting and returning to the operating system.If wants to do so , a password is needed.Whithout the pass word,exiting is the same thing as shutting the computer down.
Thank you!

Yes, most of the people in this forum can help you but what is exactly what you want?

Maybe I did not say clearly and even there were some grammar mistakes.I am very sorry for that.I will think it over and explain it in exact words.

One way would be to replace the shell with one of your own. I did this once with Windows 9x. The registry value is:
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell
By default, the shell is explorer.exe. There are many articles on the Net that can provide you with details.
Another way is via the Group Policy Editor.

I create a new project (MFC Dialog) and place a button on the dialog. The code that the button performs is the following:
<br />
CCriticalSection c;<br />
c.Lock();<br />
c.Lock();<br />
c.Unlock();<br />
c.Unlock();<br />
When I start the Program in DEBUG-Mode I expect the following behaviour:
1. The CritSec is created.
2. The first Lock is applied.
3. The second call to Lock should result in a deadlock. 
But that is not the case. The code will run without any problems.
WHY !!!!
Is there some different behaviour in DEBUG-Mode, or what?

Hi,
the CCriticalSection object encapsulates the CRITICAL_SECTION type.
The lock function calls the EnterCriticalSection API. So from the MSDN libs I found this:
After a thread has ownership of a critical section, it can make additional calls to
EnterCriticalSection or TryEnterCriticalSection without blocking its execution. This prevents a
thread from deadlocking itself while waiting for a critical section that it already owns. The
thread enters the critical section each time EnterCriticalSection and TryEnterCriticalSection
succeed. A thread must call LeaveCriticalSection once for each time that it entered the critical
section.
So it is normal behaviour

Hi all,
I have to write a program in MFC that should do:
- draw a sinusoidal signal on the screen
- draw a random signal with random dispersion on the screen
- draw the sum of the two signals
I haven't program and I'm not very interested in programming in MFC, so I'm just asking if anybody of you have done something like this and could give me a ready class, a hint, etc. If there are some ready functions in MFC I'll appreciate if you point them.
Thanks very much for the help!

There are several chart articles that may help you. One that I've used in several ocasions to represent data series is XGraph[^] that is very powerfull
I hope it helps,

I am working on something like this but
havent done up with the work and it remaining to
optimise the class.
But u can find some example in codeproject for
displaying some good sinosuidal signals.
Abuout random i dont knwo if the same class can do
the work for but will try my class to do that for u

Hi,
here is my code...
BOOL cInput::Init(HWND hWnd, HINSTANCE hInst)
{
// Free a prior Init
Shutdown();
// Record parent Window handle
m_hWnd = hWnd;
// Create a DirectInput interface \\\
m_pDI = NULL;
if(FAILED(DirectInput8Create( hInst, DIRECTINPUT_VERSION, IID_IDirectInput8, (void**)&m_pDI, NULL)))
return FALSE;
// Return a success
return TRUE;
}
i use VC++ 6.0 and directx 9 sdk
can anybody tell me whats wrong with this code ,it compiles n runs fine but while debugging at line "DirectInput8Create" it exits to the
assembly gives dialog "userbreakpoint called at .....".here the hInst is valid...n even rest seems fine for me.any kind of help is welcomed.
thanks in advance...

I have never done any DX programming, so this is just a guess.
The second parameter is supposed to be the version number for which the application is designed. You specified the DIRECTINPUT_VERSION macro, but what is the value of that macro? It is defined in the file DInput.h. So which version of the file are you using? If you are using the version that came with VC6 then it will be defined as 0x0500 (DX5).
You then provide an IDD for DX8 in the third parameter, and you say you are using the DX9 SDK.
Are you running into too many version conflicts here?

Thanks for replying.....
well the macro is
#define DIRECTINPUT_VERSION 0x0800
defined before
#include <dinput.h>
according to the msdn link below.....
http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/directx9_c/directx/input/ref/functs/directinput8create.asp
and if i am sure the there was no changes made in DX9SDK in direct input so it uses dx8 parameter here(3rd param).

Hello,
What algorithm are you testing? It's impossible for use to help you if you don't specify your problem more clear.
