help with screen lock script in windows

[traltixx]

Hi,

I have a autoIT script (taken/modified from one of the scripts in this forum) that locks a screen unless a password is given or logged off.

My question is that is it possible to modify it so that it invokes the windows screensaver whenever it is inactive? Currently, it doesn't invoke the screensaver at all for some reason and I've already tried various eliminations and it seems that for some reason this script is preventing the screensaver from activating when there is no activity.

This is what it looks like:

Thanks for any advice!

If $Lock = 1 And WinExists($ScreenyWindow) = 0 Then

Take a closer look at this line.

At this point in the code, your GUI doesn't exist. $ScreenyWindow is blank, so you're actually running WinExists(""), which will always be true. (Active Window)

Also, you're jumping right into a Message loop with no GUI created.

Both of these can be solved by creating the GUI before the loop.

As for invoking the screensaver, the current screensaver is stored in the registry here: HKEY_CURRENT_USER\Control Panel\Desktop\SCRNSAVE.EXE

Screensavers (.scr) are executable and should be run with a "/s" switch to activate.

Good luck!

I dont understand, the function to create the GUI is called before the loop.

Anyway, I tried to make the GUI before the loop but the screensaver doesn't appear after some period of inactivity.

Thanks again for the help.

I dont understand, the function to create the GUI is called before the loop.

My bad, I was running the code in my head and missed the first Lock() call.

Couple of things I noticed:

- The "Screeny" GUI keeps getting activated, even over the password GUI. This makes it hard to type a password.

- If there are multiple monitors, only the primary is covered by the "Screeny" GUI.

I fixed these and added screensaver functionality (Triggered after 10 seconds of inactivity, the same time you hide the Password GUI).

Also, I don't like the transparent window because it makes the system appear non-responsive, so I made it visible. Feel free to WinSetTrans back to 1.

p.s. I prefer to create the GUIs up front (hidden), then just show/hide them. This eliminates the risk of creating duplicate GUIs and reading messages for a non-existent one.

It's a rare case, but after deleting a GUI, a window from another app may be created and re-use that handle, so it would trick your program into thinking that the window is your own.

Thanks for the improvements. I didn't think of multiple monitors.

However, the screensaver starts for 1 second and then dissapears. Is the setOnTop triggers disabling the screensaver?

Thanks again.

EDIT: I forgot to mention that I'm using windows XP SP 2 . Maybe it makes a difference. I dont know.

[CodyBarrett]

i have a screenlock in my sig... you ll need a INI to change the pass in it whough.. maybe it will help your situation

EDIT

its called "SCREEN FREEZE"

Edited April 8, 2009 by CodyBarrett

[traltixx]

Thanks for the suggestion CodyBarrett, however your script (1) the screensaver does not activate if there is no activity and (2) the screen isn't transparent. I know how to change the (2) one but the (1) still puzzles me.

EDIT: My mistake Skruge. The default screensaver path doesn't exist on my machine. Stupid 64-bit windows. Thanks a bunch! It works like a charm now!
