Hi Braulio,
>I have to make a inventory control with barcodes and i don´t realize how to make it work. So i will appreciate so much a little help.
Usually all you need for bar code programming is a barcode font in order to display a barcode and a barcode reader to scan it. There are two types of readers, serial barcode readers and those with a keyboard wadge. The latter is easier to handle since you don't need any code in your program. A scanned barcode appears just as if the user entered it with the keyboard. With a serial scanner you need a serial library like COmmTools and have to write additional code that reads the COM-port.
