How to block shutdown/logoff in Windows Vista?

30-Nov-10 13:36

I'm pretty sure that the error message was longer than just "Backup failed for Server". If it was then it might help people, to help you, if you edited your question to include the full message.

Hi,

I'm trying to write code to block shutting down or logging off in Windows Vista.

I've tried this code but it does not work
http://community.bartdesmet.net/blogs/bart/archive/2006/10/25/Windows-Vista-_2D00_-ShutdownBlockReasonCreate-in-C_2300_.aspx

Has anyone done this and do they have a working example?

Thanks for reading!

Why would you want to do this?

Hi Pete,

Are you able to help?

I'm having a problem with remote desktop logging off the local machine when the remote session is ended. Even if this is only a temporary work around until I figure out why this is happening with vista and not xp, I would like to implement it immediately.

Pete O'Hanlon30-Nov-10 11:08

30-Nov-10 11:08

I've used a version of this code in the past, and it works fine. What problem are you having with it?

It won't compile and there are duplicate code entries as well as some other things I had to do to get it to compile.

I have something that compiled and did work as far as stopping me from logging off when I'm in front of the machine, but it still doesn't seem to block the machine from logging off when the remote desktop session is disconnected.

Pete O'Hanlon30-Nov-10 11:21

30-Nov-10 11:21

I'm not aware of anything that will prevent this happening when the remote desktop session disconnected.

Somehow it isn't an issue when I take an XP machine and remote desktop into a Vista machine. The session is saved when the XP machine is disconnected, etc.

When it is vista to vista, the problems start occurring. There has to be a way to emulate what is happening with XP.

I'm sorry that I can't help you. I'll be watching this with a lot of interest. I hope you get it resolved soon.

Thanks!

This worked last night, I'll continue to test it throughout the week. I wrapped it in a c# application that blocks logging off without verification first. The same can be done for XP, but the first command is a bit different, it is " tscon 0 /dest:console " instead.

I through the wait commands in, because a few times that I was testing it would release the session before the lock command could run and then it would not lock the machine, so an unlocked desktop was left sitting at the office, not something I wanted to happen. Thanks for the help and encouragement Pete.

tscon.exe RDP-Tcp#0 /dest:console

wait 1

rundll32.exe user32.dll, LockWorkStation

wait 1

exit

Rebooting to safe mode...

How could one reboot a local computer to safe mode using C#?

I have used google to search for this and not finding much. I did find a question posted for the exact same thing here on codeproject from '06 but the reply the guy got was this was not possible.

I see this for shutting down or rebooting:
http://pinvoke.net/default.aspx/wtsapi32/WTSShutdownSystem.html[^]

Before you say this cannot be done, I currently use a Windows application that can reboot a computer to safe mode. Not sure how they do it, but they are somehow.

Henry Minute30-Nov-10 7:52

I have never tried this but your question intrigued me so I did a little googling.

If the OS on the computer is XP or before how about temporarily editing Boot.ini to add a /SAFEBOOT switch (source[^]), with a runonce registry entry to reset afterwards.

I'm not sure how Vista and Weven work but a similar technique might be possible.

Jacob D Dixon30-Nov-10 8:20

Well you came up with more than I did. I was hoping to get around manually editing the boot ini file with my code. Even if I did that would it go off once it booted into safe mode or will it continue to boot into safe mode every time it reboots?

Note:
I guess I could try opening reflector and finding this code and how they are doing it. Do you know if this is legal for me to do?

Probably not, if you use the code directly. Although if it's not obfuscated there is no harm in just having a look, to satisfy your curiosity.

I used to do a similar thing back in the DOS days with the Autoexec.bat and Config.sys for some programs (Games mostly) that required non standard settings.

In your situation, make a copy of Boot.ini, rename it Boot.ini.safe (safe mode), or similar. Make another copy and rename it Boot.ini.std (standard mode). Modify the .safe file to include the /SAFEBOOT stuff.

BTW: Try the next bit out manually first, to make sure that it works.

I used to do the next bit using batch files, you could do the same, or write a small app to do it.
1. Delete Boot.ini
2. Depending on whether you're going from standard to safe, or the other way, copy the Boot.ini.safe/Boot.ini.std file as Boot.ini.
4. When going to Safe mode add the entry to Runonce in the registry to run the app/batch that prepares for standard boot on next restart.
3. Restart.

[Edit]
Just discovered that step 4, above won't work See Notes section in this[^].

Hmmm and it seemed like such a good idea. Frown | :(

LOL.

Let me give some things a try. Your suggestions got me further than I was. There are some things that I want to know how this application does stuff. It also provides like a VNC redirecting type function where the control center application is on your computer, then you have the server, then you have agents (which could be on a different network behind a different firewall). So the agent started the VNC with the server, then somehow the server redirects all that traffic to the control center.

It is all a learning curb for me. So my way of learning is trying to duplicate the server / client application they made (slimmed down version of course).

Let me try some things and also snoop around in their code and I'll let you know what info I come up with. thanks for the information you already provided!

thanks to both of you.. now I know how to do routine at least it works.. I usually restart to Safe/DOS mode to remove manually the Autorun.inf of any USB Drive suspected with virus. this at least I can prevent it from transferring to my hard drive. I just copy only the Docs and Xls files.

c# Webbrowser control with frames

I am trying to change the "onload" event of the Body in a frame. My problem is when I using the GetAttribute method on the Body it returns "System._ComObject" as a string rather than the attributes value. Please note it is not returning an object of System._ComObject, just the string.

I tried just doing the change via Body.OuterHtml but that throws an expception of NotSupportedException. Which is odd seeing as it is a property that says it allows "get and set" operations.

WebBrowser.Document.Window.Frames[i].Document.Body.GetAttribute("onload") = "System.__ComObject"

Any ideas on how to get this to behave as it should would be greatly appreciated. Even just a point in maybe the right direction. Also I did try this using "mshtml" objects and all it got me was the actual System._ComObject. However, I had no idea how to covert that to the string it was supposed to actually represent.
