On the apparel products at present are labeled with RIFID chip barcode stickers, after foreign supermarkets have no cashier, directly come out automatically know how much to pay, then you pay by electronic wallet!

So for our suppliers to the number of products requires a higher precision, because the customer warehouse as long as there is a system put a box in a door, there are how many quantity, what all know! If the quantity is right or wrong size will return! Actually wrong reason is that there is no tape barcode sticker on some clothes!

Customer gave a RIFID scanning gun, can one-time scan multiple, such as a case of 200 things, you put the scanning gun (about 30 cm) around the box, open a notebook PC, it will quickly jump out 200 lines of code, if more or less, that means this box items must have been some things did not stick bar code

Now want to write a program, as long as the content in the text box the number of rows read it out, and the content of the row to the database to check the size!

Could you please give an idea! DELPHI7 good at something! Other basic already forgot

Then you traverse all, then, in turn, query the database,
