| Hello!
Does anybody know how to determine if MS Windows is currently idle.
Menas no applications are running and do something? Maybe there is
Some sort of a Windiows messaage sent?
Thanks in advance!

Look at SetWindowsHookEx
- I've never made it work under VB

thanks for the hint. Base don this function I found an example on
www.vbaccelerator.com. The only problem is that the example uses the
API only for a single thread and not for the whole system. Any ideas?

A real example should be in a non-VB non-AX DLL
- that gets magically mapped into the memory of each process
Generally the multiple instances communicate to one point using
SendMessage
If SetWinwsHookEx is used within an EXE it just grabs the stuff for
that EXE - I guess you found that example
An easier solution is to cheat and just monitor the mouse position and
the keyboard using a Timer
- personally I would do that as I've read posts saying that a global
hook is known to conflict with a number of established Apps
If you really want to use a DLL to establish a global hook then I
could point you to some Delphi code that does it

| Thnaks for your help, but Im not familiar with delphi or C and I do
not have the cmpilers so I couldn't compile the sources. But thanks.
Heard of a already compiled component which hooks the idle status?

This is the link I have
- but I checked it and it is invalid
- I also tried the Wayback machine - no success
www.zenobits.com/projects.php/1/#TIdleDetector
You might be able to hunt something out
- probably me riling the guy into explaining what was going on
I would seriously go for the 'cheap' alternative that I suggested
earlier, monitoring the key state is a simple way of making sure that
the machine is ... sort of ... idle

Here's another. I missed part of the thread so I'm not sure exactly what the
requirements are. This is a very simple way to check idle using a timer and
a couple of API calls to see if there's any keyboard/mouse activity. The app
itself doesn't need to have focus.
Detect Idle and App Auto Shut down

While there, might as well take a look at this (below) since I saw someone
mention something about apps communicating with each other. I went a bit
over-board on this one. Had plans for it that never took shape.
Communicate with another instance of your app

| Thanks, I think I will do it in the way you suggested by monitoring
key strokes.
