Forcing a shutdown/logoff

Try this:

ExitwindowsEx(EWX_LOGOFF OR EWX_FORCE,0) //logoff

ExitWindowsEx(EWX_POWEROFF OR EWX_FORCE,0)//shutdown



Good luck!!

try  using or instead of +

ExitWindowsEx(EWX_LOGOFF or EWX_FORCE,0);
ExitWindowsEx(EWX_REBOOT or EWX_FORCE,0);
ExitWindowsEx(EWX_SHUTDOWN or EWX_FORCE,0);  

snap :)

I have replaced '+' with 'or' but it still does not work. The screen just flashes, displayes the logon box, and everything is still running.

Any other ideas?

Found this on the M$ Knowledgebase:

INFO: ExitWindowsEx() Does Not Shut Down or Restart Win 95/98/Me (Q220706)

--------------------------------------------------------------------------------
The information in this article applies to:


Microsoft Win32 Application Programming Interface (API), used with:
the operating system: Microsoft Windows 95
the operating system: Microsoft Windows 98
the operating system: Microsoft Windows Millennium Edition


--------------------------------------------------------------------------------


SUMMARY
When you use the ExitWindowsEx() API on Microsoft Windows 95, Microsoft Windows 98, and Microsoft Windows Millennium Edition (Me) to shut down or log off the computer, the action fails intermittently on some rare hardware or driver configurations.



MORE INFORMATION
This behavior is caused by the design of the hardware or driver.

In most cases, a cooperative (user-initiated) log off or shutdown is recommended for Windows 95, Windows 98, and Windows Me.

In cases where the application must initiate shutdown or log off, it is recommended that you use the ExitWindowsEx() API to implement a non-forced programmatic log off or shutdown. A non-forced log off or shutdown allows users to save their work and settings.

For more information about ExitWindowsEx(), please see the Win32 Platform SDK documentation.

Q216638 HOWTO: Programmatically Force Windows 95, Windows 98, and Windows Me to Log Off

PS. Q216638 refred to above has some C++ sample code... here's that too if you can use it. I don't have the time now to translate it for you. sorry.

I don't know how to use C but if you could tell me where I could get a compiled version of the code, then I could just execute it from within my application.

Or prehaps a component of somekind?

Thanks for clearing up that it was ExitWindowsEx failing to work.

listening

Instead of using EWX_POWEROFF alone you should better use EWX_POWEROFF or EWX_SHUTDOWN, respectively EWX_POWEROFF or EWX_SHUTDOWN or EWX_FORCE.

Regards, Madshi.

this might get the shutdown dialog box

{declare the dll procedure}
procedure ExitWindowsDialog(Handle: THandle); Stdcall; External 'Shell32.dll' Index 60;

procedure TForm1.Button1Click(Sender: TObject);
begin
  ExitWindowsDialog(Handle);
end;
