Using .NET 2.0...
How can I cause Windows Forms application to shut itself down after a period
(say 15 minutes) of [no user activity]? Specifically, I'm wanting some
options for detecting that the user is somehow using the application (either
detect mouse clicks or keyboard input).

The idea is that if the user walks away from their computer and is gone for
an extended period, then the app will close itself down to help curb
malicious use.

This is a Windows Forms MDI app.

Thanks.

Check out this code for inspiration:

Just wondering if this can be done with 1.1 as well?

It is easy to implement it in client side using script.

It works like this:

(1) When the page OnLoad in client side, set a timeout to process it.

(2) capture mouse activity in this page and reset the timeout

Following is the javascript:

var tID = 0;

var IntTime;

function OnActive(page)

{

clearTimeout(tID);

tID = setTimeout("WindowIdle()", IntTime);

}

function OnPageLoad(page, timeout)

{

var body = page.document.body;

if (timeout > 0)

{

IntTime = timeout;

}

// reset the timeout when the page is active

body.onclick=OnActive;

body.onmousemove=OnActive;

tID = setTimeout("WindowIdle()", IntTime);

}

function WindowIdle()

{

// do whatever you want, usually redirect to another page

}

Hope it is useful.

Hm... The OP posted the question to the Windows Forms group ;-).
