Detect change in marked area
« on: March 03, 2016, 11:03 AM »
Hi,

I just found this brilliant forum and hope some of you guys will be able to help me out :)

A windows program that will detect a change in a "marked/selected" area of the screen, and play a sound if it changes.

Example:
  • Start program
  • Select what area of the screen to monitor
  • Select sound file to play
  • click start button

The software will then "monitor" the selected area of the screen and play the sound file it it changes.

This will be used to monitor a game interface (window mode) and alert me if something changes (in a defined area of the window).


I hope one of you find this exciting and decide to give it a try :)

Exactly the same request has been posted on this forum some time ago, but I don't recall if it was answered... :-[

If it was this you were thinking of it wasn't ... but there is: Skrommel's PixelNotifier

Sorry to revive an old post, but I too need this. 

I did pulled Pixelnotifier program and do not understand it.  I want to monitor an area of the screen (not a pixel) and if a % different change happened make a sound and launch a program maybe.  I would use it to monitor a video camera windows for change.  Sure other will use it for stock symbol changes and more.

I did have a program from years ago in autohotkey from Skrommel, but it never worked and I did not follow up with him.  Hoping someone has written something like that.  Or better documentation for pixel notifier.

I can upload the Skrommel code I have if needed.

Thanks.
