Reading data from hand held barcode reader

[Rod Caddy]

I am working on a project that should be quite simple but I believe I am 
making it much harder than it has to be.  I have created a file that has 
basic data for inventory.  The concept is that when the empty record is 
displayed a barcode will be read and will fill all the fields except the 
quantity.  The quantity will be entered manually and this record is 
saved and you move on to the next record.  The only field that the user 
would have access to would be quantity.  My problem is at what point do 
I read the barcode so it can be parsed out to the fields.  I realize 
this should be simple but for the life of me I cannot seem to wrap my 
brain around this.  Thanks for any suggestions you might have.
