Is there any method/Software/Library which can be used to read bar codes and which can be implemented in Foxpro 2.6 for DOS? Please give the details if any.
 
Hi,
If you are using barcodes scanning, the scanned info is accepted and put in the keyboard buffer. So the buffers gets into your GET data buffer.
TO give a small example.. if you have issued a GET statement and followed with a READ command... The cursor will will be waiting at your GET for the user to input data. At this juncture, if the SCANNER reads the BARCODE, the data gets and fill the WAITING cursor position.

If the Barcode includes a CR, then the cursor gets the CR as well and jumps to next field after the VALID event etc. getting fired as if the keyboard was used.

So that is all to it and it is simple. Only careful thinking required as the sequences followed, the errors catching etc...
Best of luck ramani :-9
