Hello!
I need to find Desktop Information Soft...
For example: web-store, after receiving an order => the program must alert manager...
Ideal is... program need to periodically requests an php-script for new orders, and if it was => inform a manager
UPD. I'm finding something like "reach inform application", with server side developing... Much (as it may be) customizable...
The easiest way to do this (i.e. a way that does not require client side programming) might be setting up an RSS feed in PHP.
There are dozens, if not hundreds RSS feed readers out there for every conceivable platform; I'm pretty sure you'll find one that matches the requirements. If I remember correctly, Windows Vista and/or 7 have a built-in sidebar widget to display RSS feeds.
You may use built-in Windows scheduler and some script (PHP), which would connect to your server, check whether new orders arrived, and exec() notepad with opened information about order :)
Another way is, send e-mail notifications about every new order.
Your best bet is to use Adobe AIR to develop a simple JS based desktop software which polls your server every X seconds to see if there is an update.
