RE: Can't lock keyboard on errors - Resolved

["Dave Murvin" <Dave.Murvin@xxxxxxxxxxxxxxxxx>]

Thanks Dave.

They have another application here that does what you suggested, but I
was hoping to get it to work with the DDS code.  I ended up doing
something similar to your solution.  I created s simple window without
any input fields that displays the error message.  They must manually
press a function key on the window to return to the application.  Text
for the window error message and the command key text are input parms
and the response is an ouput parm from the window, so program can be
used anywhere.

Thanks

Dave

I'm not sure why I thought of this since it's been a couple of days, but
I
did.  When I used to work with Telxon/Symbol scanners I ran into the
same
problem of user's not stopping their scanning to read error messages.
The
solution I used in that case was to throw up a screen that displayed the
error message but had no input-capable fields.  Because there was no
place
to type, the scanner wouldn't scan, and they would stop to read the
screen.
Even though the scanners were DOS-based the integration between the 5250
client software and the hardware was pretty good.  I've looked at other
Windows-CE scanners but they didn't have that integration.  This
technique
did NOT work with scanners plugged into a PC keyboard jack.

I haven't worked nearly as much with barcode scanners for the past few
years so things may have changed.
