Media player in full screen until I make my userinput window active

[computergroove]

I have made a script that does 2 things:

1. When I start the program it brings up a window that asks for a user input. When the user enters some input (scans a barcode in a hand scanner) the script identifies the movie associated with that barcode and plays it on the screen.

2. When the video is done playing the user input screen becomes the active screen again so a user can scan another barcode to play a video.

The customer has requested that after 20 seconds of inactivity the program start playing all the video files in random order. I have made a lot of progress on this. One of the problems I am having is that while the movie files are playing in random mode, I cannot make the user input field active without causing the video to exit full screen mode. I want the ability to accept user input at anytime and if a movie is playing I want the script to immediately start playing the new user video request. Here's my code so far:

you would need a $pid when you start the external player so you can Kill it with the PID

;waits until no instance of notepad.exe exists

ProcessWaitClose("notepad.exe")

; This will wait until this particular instance of notepad has exited

$PID = Run("notepad.exe")

ProcessWaitClose($PID)

now for detecting the 20 sec idle i would add an adlib function to check if mouse or keyboard is pressed with _ispressed()

or check in the main message loop (whatever works better)

when idle for 20 sec - start a random movie with PID , if mouse is moving , kill process PID and display input again

AdlibEnable("myadlib")

;...

Exit

Func myadlib()

EndFunc
