I designed an Access application to manage the counting and verification of
the ballots for the voting procedure. A barcode scanner is used to enter the
ballot to the Access application. The work-flow of this application is the
user first scans the barcode then click on it once to send the barcode to a
text box on a form, then user click on the barcode scanner again to proceed
with the barcode verification and counting process. Once this process is
completed, a passed/failed symbol/image popped up then a message box telling
the user about the result of the ballot with a "OK" button on it. User click
on the "OK" button using the barcode scanner and set the focus back to the
text box for the next barcode scanning. The entire process takes about 1 to
1.5 seconds. The problem is after the barcode is sent to the text box, user
sometimes double-click on the barcode scanner to proceed with the counting
and verification process, as a result the code is stopped at the line where
it try to display the symbol/image of that ballot. It is an image control
with an embedded image I have to place on the "my document" folder to make
it work. Is there a way I can temporally disable any input either from the
barcode scanner before the message box pop up? Thanks.
