问题
I have the need to either prevent, or restrict, the termination of a VB.Net application. I have no problem with Admin killing the application, but not a user. I've been unable to come up with a solution for this. Is there maybe even a way to set local policy to prevent termination by non-admin?
Note: I've seen this question asked before and people ask "why", assuming this is for a malicious purposes. This is a GUI app that MUST remain on top of the users windows per policy.
Update: I know this is possible SOMEHOW... I have seen applications that, when I try to terminate them through the task manager, I get a permission denied. That's what I'm trying to do...
回答1:
If you handle formclosing event and say e.cancel if it is a normal user then it will be handled in your boundary. But you cannot enforce policy until and unless there is physical restriction applies in windows. I feel if you can remove the .NET keyword and put the question to IT specific guys it will help. In .NET you can do other than what I have explained in the initial statement.

The following code will stop your form from closing (and should therefore stop your application closing) when the user hits the red X in the corner:
Private Sub Form1_FormClosing(sender As Object, e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
If e.CloseReason = CloseReason.UserClosing Then e.Cancel = True
End Sub
You can't stop someone running task manager and killing the process though, but you can stop them from running task manager using group policy
