How to keep program from being shutdown via NT task manager

[Lawson]

I'd like to have a program run in the back ground, not be shown in the NT task manager Application listing - these
things I can do.

I'd also like to do one of two additional things. Hide the program from the
NT task manager Processes listing, or be able to have the program unable to be shutdown like the system exe's -
when a user tried to shut one down using the
processes listing in task manager, a window pops up and says
"The operation could not be completed. Access Denied."

Thanks in advance.

Lawson.

I don't know alot about VB but i program alt of languages and I am trying to learn VB. Just a suggestion (don't know if it will work) but can you write a function that executes on exit that would recall the program? or write another program with a timer pulse of 1 and boot the program if it is closed. Just some small ideas from a newbie

Hope that helps,

Thanks for the input. Yes, those suggestions could be the
next best options, if I cannot do what I really want.

You can use the form_QueryUnload method to prevent the app from being closed. If UnloadMode = 3 then set Cancel to True.

The following are possible values for UnloadMode.

QueryUnload values for UnloadMode

Constant           Value  Description 
vbFormControlMenu  0      User has chosen Close command from the Control-menu box on a form 
vbFormCode         1      Unload method invoked from code 
vbAppWindows       2      Current Windows session ending 
vbAppTaskManager   3      Windows Task Manager is closing the application 
vbFormMDIForm      4      MDI child form is closing because the MDI form is closing

Thanks for the info, but this still allows for user to shut down program thru the end task option in task manager/process list.

Why do you want to write an indestructible, phantom program?

I know that I wouldn't want any program running surreptitiously on my PC that I had absolutely no control over, and the Task manager is typically the last resort.

I already feel like I'm constantly competing with Microsoft for control of my own PCs. So, what's the point?

Becuase I am writing an app that monitors people's internet usage and they can disable it if they want and turn it on when they want. THAT is not good.
