How about making your form so big that it covers both screens?

I don't have twin monitors on this PC so I can't test it for you.

As I've understood it, he'd like to have two "views": one which would be used by cashier (and viewed on one monitor), and another one which would (on another monitor) display item and price of a product currently scanned by a barcode reader (so that customer might see what's really scanned, how much it costs etc.).

LF,

Have you got twin monitors to test whether a form can spread over them both?

I believe I understand what he wants and I can see no reason why two blocks displayed on the same canvas spread over two screens would not give him the result that is being sort.

I apologize; I didn't understand that you understood it.

I don't have twin monitors either, but ... I *think* that if a window is maximized, it spans both monitors so left side of a form (i.e. one of the blocks) would be displayed on one monitor, while right side would be on another one.

That's all that's needed isn't it?

Can you open a new form using 'open_form' and get it to start on the second screen?

I have done considerable work with POS systems, but... I have not done what you ask specifically. Lack of experience has however never stopped me from opening my mouth to give advice so here goes:

I see one option off the top:

1) you need an operating system that supports applications on two different monitors, most do these days so no problem there

2) you need to understand the features of your operating system and video device drivers to know how to use multiple displays at the same time. Again I see people doing a lot of this at work so can't be that tough (I never had a need myself).

3) you need to find out if the monitor you are being asked to use is special in some way, specifically, ask if they provide multi-monitor support software. If you are just using plain jane LCD displays then you your OS and video card will have alrady provided what you need.

from here I suggeset the following:

1) your normal application
2) a second oracle form to be run in an independent forms session and displayed on the second monitor by using the multi-monitor software provided by your operating system, and/or devices.
3) do asynchronous communication between forms. This could take several shapes:
a) go old school, do something in the database with autonomuos transactions, database triggers and database alerts.
b) use advanced queueing to do your communication.
4) based on your communication vehicle, your second form would would either listen for a database alert, or it would listen for work on a queue.
5) when the second form finds work to do (as evidenced by a message it recieves either through the alert, or the queue), it would do the work, then go back to listening. Make sure your "listen" is a cpu friendly wait (alerts and advanced queueing both support this).

all sounds very do-able, and even interesting.

Good luck, Kevin

Please also look at http://www.orafaq.com/forum/t/88668/67467/ and make sure you have a version of Forms that can handle multiple monitors if you intend using a 'menu' or 'button' on the second screen.
