Credit VB/SQL

I need a credit module developed for a custom VB 5 program with a MS SQL 2000 backend to compliment the allready in place invoicing module. The back end houses multiple tables (Header, Detail, History) that will need automatically updated when crediting. I want the end user to select previously invoiced items from History (preferably using MSFlexGrid for display and selection). Upon crediting the selected item, the user must be able to change the QTY to credit and also choose whether or not to credit freight and tax or partials thereof. There should be a print option after all information is written to the proper tables. At this time, we are using html/asp for printing but that is expected to change so the option to change printing procedures is a must (I would be able to do an amendment to the code for this) I would need this in code form so I can drop it in our exsisting program. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Our desktops are running Win2000 Pro/Win XP Pro Our Server is Win2000 Server Our database is SQL Server 2000 the program should be written in VB 5 to match current code Internet Explorer 5.0 + Office 2000 +
