I'm creating a backup program, and I need to be able to open files with the ACCESS_SYSTEM_SECURITY privilege.
However, when I specify this privilege in my call to CreateFile, it tells me I'm missing a "required privilege" even when I run it as Admin.
This is on Vista.
What are the steps for getting the required privilege to open files with this access right?

Hi,
I wanna know how could i drew a few cercles just by typing with lines of code. I'm under MFC on MSVS 6.0. is there some struct that could help me to drew such shapes?
hope that i wrote right 
And thank you.

Do you mean something like this?
void CMyWnd::OnPaint()
{
CPaintDC dc(this);
dc.Ellipse(10, 10, 50, 50);
}
Or do you want to write the circle drawing code yourself? If so, Google "circle drawing algorithm".

did ever heard about loops?

Exactly.
BTW turn off your CPMRU, it is not fair using such device for this kind of guess.

lol, I know about loops but the prob that i dont know how many circles that the user wanna, let say 2O so how could i declare the 20 vars for those cercles
for (i=0 ; i< 20; i++)
{
Cercle[i].....??
}

You could store the coordinates in an array.
An array container that grows automatically would be even better, like a vector or a CArray.

yup i'm using a vector 
but is the form "Formview" suitable for drawing or should i select another type?
i'm new on drawing :s

Ok I'tested on a FormView and it works i had a white circle it was a stupid querstion

You can draw on any window.
A CFormView is useful when you have controls you need to layout on the window like a dialog window.

You don't necessarily have to write the code three times.
However you write the code, it must call Ellipse() three times.
These are two equivalent examples:
void CMyWnd::OnPaint()
{
CPaintDC dc(this);
dc.Ellipse(10, 10, 50, 50);
dc.Ellipse(30, 30, 70, 70);
dc.Ellipse(50, 50, 90, 90);
}
void CMyWnd::OnPaint()
{
CPaintDC dc(this);
CRect CircleRect(10, 10, 50, 50);
for (int i = 0; i < 3; i++)
{
dc.Ellipse(&CircleRect);
CircleRect.OffsetRect(20, 20);
}
}

when i click on the butoon nothing is drawin !!!
is it a prob of reference to the dc .?
<br />
void CSecondForm::OnButton1() <br />
{<br />
<br />
CPaintDC dc(this);<br />
dc.Ellipse(20, 20, 100, 100);<br />
}<br />

You can only use a CPaintDC when responding to a WM_PAINT message (in OnPaint()).
Use a CClientDC in your button click handler instead...
void CSecondForm::OnButton1() <br />
{<br />
<br />
CClientDC dc(this);<br />
dc.Ellipse(20, 20, 100, 100);<br />
}

You'll need to select a font into the DC (unless you want to use the default font), then you can use any of the
GDI text rendering functions (CDC::DrawText[Ex](), CDC::TextOut(), CDC::ExtTextOut(), etc.) to draw the text.

CClientDC dc(this); <br />
dc.Ellipse(10, 10, 70, 70);<br />
dc.Ellipse(20, 20, 70, 70);<br />
dc.Ellipse(30, 30, 70, 70);<br />
dc.Ellipse(40, 40, 70, 70);<br />
CString str;<br />
str="Cercle";<br />
CDC::TextOut(100,100,str);<br />
}<br />
CDC::TextOutA' : illegal call of non-static member function
i atried even with CDC::TextOut(100,100,"Cercle");
Same prob

I found it, srry for the multipost. 
void CSecondForm::OnButton1()
{
// TODO: Add your control notification handler code here
CClientDC dc(this);
dc.Ellipse(10, 10, 70, 70);
dc.Ellipse(20, 20, 70, 70);
dc.Ellipse(30, 30, 70, 70);
dc.Ellipse(40, 40, 70, 70);
CString str;
str="Cercle";
dc.TextOut(100,100,str);
}

You got it 
I notated it that way ("CDC::") to show what class the methods were in - the CDC class.
