WIN CE barcode application

This is for a simple Win CE App for my symbol terminal MT2000 I have to control the preparation of customer order. When a customer make an order our software divid it depending where are located our product We have seven "zone" (Mezzanine, dock, frigo 1, frigo 2, info, appro, tech). What i need : When i choose the zone (screen 1), the app show me the list of order for this zone (screen 2). When i choose an order, the application start to process order with a new screen (screen3) On this new screen we have the detail of each product of this order order by emp and on the top we have a text input ( or barcode control) to put the barcod. So for example, a customer order 6 glass of water, in the screen 3 i've to see every detail for the article "glass of water" and the number ordered by our customer. While i don't have put 6 time the barcod in the textinput, the app stay on this article. Once it's done, the app change to next article. If i have to scan more than 15 time, the app let me put the number manually. When all article are done, the form show me a success form If i press to "return" button, a dialog open and ask me if i'm sure, if i press ok, i go back to the menu with all zone, else i stay where i was. Warning, this app need to work with Net framework < 2.0 I provide you the first application i've done in vb.net, you have to use it as a model (screen size, ... ) I provide you a part of a python script (with a lot of bug but working) I can also provide you the full working IDE for win CE with SYMBOL SDK on a vmware image
