How we can Shutdown a system OR Restart or Log Off or Hibernate or ....

Introduction

How we can Shutdown a system OR Restart or Log Off or Hibernate or ....

This program is a good example for this Task.

I define Fuction as a Library , and then voice it into my program(Name my program is :TurnOffWindows ).

according to :

Merge Library TurnOffComputer to program.

// TurnOffWindowsDlg.h : header file
//

#if !defined(AFX_TURNOFFWINDOWSDLG_H__1AA55971_5022_4C8B_9700_D0A6791694F2__INCLUDED_)
#define AFX_TURNOFFWINDOWSDLG_H__1AA55971_5022_4C8B_9700_D0A6791694F2__INCLUDED_

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

//***********

#include "TurnOffComputer.h"

//*************

use from this Library into my program.

void CTurnOffWindowsDlg::OnButtonRun() 
{
// TODO: Add your control notification handler code here
UpdateData(TRUE);

CTurnOffComputer MyTurnoff;

MyTurnoff.Active(m_radio);


}

Notice :

m_radio is a integer value .

if  value m_radio is 0 ,So your computer will Shutdown .

Too :
<PRE>    1-->Restrat

    2-->Log Off

    3-->Stand by

    4-->Hibernate

Hi. It seems to be very nice (if it works under limited user accounts) but I could bnot download either source code or the demo. I'd be glad if you correct the links. Thanks Mohammad

Look in your MSDN Platform SDK help files in Visual Studio... Search for "SHUTTING DOWN" ... this is just basically a copy/paste of that code... In case you can't find it, here it is:

Shutting Down
You can use the ExitWindowsEx function to shut down the system. Shutting down
flushes file buffers to disk and brings the system to a condition in which it 
is safe to turn off the computer. 
                    
Windows NT: The following example enables the SE_SHUTDOWN_NAME privilege and 
then shuts down the system. 
             
HANDLE hToken; 
TOKEN_PRIVILEGES tkp; 
 
// Get a token for this process. 
 
if (!OpenProcessToken(GetCurrentProcess(), 
        TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) 
    error("OpenProcessToken"); 
 
// Get the LUID for the shutdown privilege. 
 
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, 
        &tkp.Privileges[0].Luid); 
 
tkp.PrivilegeCount = 1;  // one privilege to set    
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; 
 
// Get the shutdown privilege for this process. 
 
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, 
        (PTOKEN_PRIVILEGES)NULL, 0); 
 
// Cannot test the return value of AdjustTokenPrivileges. 
 
if (GetLastError() != ERROR_SUCCESS) 
    error("AdjustTokenPrivileges"); 
 
// Shut down the system and force all applications to close. 
 
if (!ExitWindowsEx(EWX_SHUTDOWN | EWX_FORCE, 0)) 
    error("ExitWindowsEx"); 
 
For more information about setting security privileges, seePrivileges.

Further, I'm not sure this justifies a separate class - it's such a small snippet of code. Practically, in a project, it's primary use would be to intitiate a restart if system settings were changed which required restart to take effect. Even then, I would either use it as a standard function, or add it (as a simple function) to a DLL containing shell/system functions.

In business, if two people always agree, one of them is unnecessary.

Hi,

This can be a very handy class, but I have some comments:

I don't want to use 1 or 2, I want to use constants:

#define LO_RESTART 1
#define LO_LOGOFF 2
#define LO_STANDBY 3
#define LO_HIBERNATE 4

Also, I think you can make the functions static. Then I don't have to create an object of your class, but I can use it directly:

void CTurnOffWindowsDlg::OnButtonRun() 

{

    // TODO: Add your control notification handler code here

    UpdateData(TRUE);

 

    CTurnOffComputer::Active(LO_RESTART);

}

And I am missing an option to turn off the pc.

I think this will make the class much more usefull!

Does this look feasible or not?

Best regards,

Geert

Good ideas, also make those constants a class enum so you don't have to worry about them being defined elsewhere Edit: I don't seem to be able to download the demo or sources, the links are 404s

yes, he has to define it at the top of his .h file:

#define LO_RESTART 1
#define LO_LOGOFF 2
#define LO_STANDBY 3
#define LO_HIBERNATE 4

Then I never have to worry about anything. If I include the class, I can just call it static. It makes it much easier to use. I think it is too much work to (not really, but it's the idea) declare a variable and then call the function.

I have another question:
Why is this topic for advanced people only? I haven't looked at your sourcecode because the files are corrupt, but I can't imagine it is so hard to turn off a computer.

But maybe I am wrong (mostly I am Wink | ;)

)
