>>>I have a barcode scanner with a built in decoder, plugged into Com1.
>>>I'm trying to read the barcode that was swiped, and enter the contents into a textbox on a form. I can not get the OnComm event to fire.

::snip!::

>I agree here 1000% - the wedge scanner, which ats as if the data had simply been typed into a field, is much easier to use - no special code needed to access it. that's what we use at Weatherhill for our in-house apps (both the PB Ascent software for our shipping station, and our own code for processing returns. We use a hand-held CE device to collect data in the warehouse, and then dump the stuff back into a data file that VFP processes after the fact for doing inventories and the like.)

I wrote a receiving program last year using a Spectrum 24 RF hand-held scanner and WaveLink Client/Server software. The Spectrum 24 has an alphanumeric keypad and a 20x8 LCD display which I took advantage of to allow the operator to input data by hand in the event the data wasn't available in barcode form. The WaveLink software treats the scanner as a 'dumb terminal', so all the code runs wherever the WaveLink Server software is installed.
The really sweet part (aside from being TOTALLY mobile) was the flexibility of the solution.
The really sad part (aside from the cost) was trying to fit a receiving screen into a 20x8 display. All in all, tho, it was a lot of fun...

BTW, FWIW, I agree with the wedge scanner suggestion. Much easier.
