For keyboard wedge scanners it is you describe. Give the focus to a text box
and scan the barcode (you may need to set up the scanner for 2d, check the
manual) the scanner should relay the data as if it was typed from the
keyboard.

You may get some vertical bars in the text box representing characters which
can't be displayed.

I prefer using the serial type scanners along with the MSComm control. This
eliminates the need for the user to place the focus on the proper text box
before scanning. In fact the application itself doesn't even need to have
the focus.
