Inventory program for Windows CE 5.0 PRO device with bar code reader

Hello, i need simple inventory program for Windows CE 5.0, similar to program on this web page: [login to view URL] On that web you have free demo so you can see what i am talking about. I need for program to have all like that program (so only for inventory - menu 03) plus few things. Program must do: - when i select invetory i must enter first user - after user i need to scan location - - after that i need to scan article number - after that i need to enter quantity - on this screen i need to see item position in warehouse. If i scan some item with wrong location (let's say i am on location 01 and i scan item that must be on location 02 program must warn me about this). - i must be able to see all part that are on location i scan (so after i scan location i can see list of parts that should be there) - after i finish scanning on some location program must warn me if i missed some item from that location (so for example it must warn me that i am missing from position some part) Device used on is Unitech PA660 - if you need SDK for this you can find it on internet. Work must be done in 3-5 days.
