Difficult Question : How to pick up window activity

[phreakazo]

HI,

We have a window that shows some alarms when system are down.. However this wonderfull product doesn't have audible notification implemented.. how about that.. So we have to stare at the stupid screen every 2 minutes..

Now I know in VB there are some special API to pick up a window's name and so on...

Now can I also pick up some CHANGE in the window.

To be clear I would like to run a VB program in the backgroun wich checks a window every 5 seconds for a change, when it is changed It needs to play a sound..

the sound part I can program no problem there.. it's just the first part ..

Thanx for any input here..
Bye

Subclassing is what you need. For a simple tutorial go here http://www.vbsquare.com/articles/subcls/ .

For a simple way to do it, using some rather cool controls, go here http://www.desaware.com/SpyWorksL2.htm .

Thanx,

this is some quite complicated stuff if you are not used to it... I will try the demo of desaware but I think I need some additional programming to it to achieve the results I need ....

But thanx for the input
