shut down of windows NT through an application running with LabWindows/Cvi

[Fab 212]

Can you explain me which instructions I have to use for shut down windows Nt from an LabWindows application.

[RobertoBozzolo]

According to Windows SDK you should use
ExitWindowsEx(EWX_FORCE, 0);
Look at the reference for this function for a detailed description of the first parameter (for example you could simply log your user off...).
You must #include in your project.
I used it in Win95 and Win98 and it works well. I hadn't tested it in NT, but it's simple to try...

Hope this helps.

Windows NT is a bit different to Win 98

This code should do the trick for you.

#include "stdafx.h"
#include "WinUtil.h"
#include "WinUtilDlg.h"
#include "WINUSER.H"

void shutdow()
{
HANDLE hToken;
TOKEN_PRIVILEGES tkp;

// get the token for this process
if(!OpenProcessToken(GetCurrentProcess(),
TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken));

// get the LUID for the shutdown privilegde
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid);

tkp.PrivilegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;


//get the shutdown priviledge
AdjustTokenPrivileges(hToken, FALSE, &tkp,0,(PTOKEN_PRIVILEGES)NULL, 0);

ExitWindowsEx (EWX_SHUTDOWN | EWX_FORCE,0);
}

Hi Mark,

Do you have a DLL or EXE version of the c code (shutdow)? I am in a similar situation with winnt4, where I want to logof and shutdown from within the program by calling a function. I have labview 6i and I do not have any compilers.

Thanks
