I have a program where were are scanning bar codes for a scanner
hooked up to a laptop via USB. The scanner adds the CRLF at the end
of
every scan. I need to figure out how to make the program to caputer
the number scanned so i can use it in my program. Right now i have
them scanning the item and then hitting a button on the form to enter
the number and I want to make it so they do not have to hit the
button. Can anyone help me on this.

Most usb bar code readers act as a keyboard emulator, so you should be
able to use the typical keypress/keydown/keyup events.

I have tried that and it only grabs the first number of the barcode.
Do you know anyway around this?

I believe the event(s) should fire for each number? Also what is the
barcode scanner inputting the data into, a textbox? If so you could
just use the TextChanged event to start your code.

Seth,
Read them all and look for the CRLF.
Stan
Are you done with the input when the scanner sends the 'enter'? Can you make
the button the 'default' button for the form? Otherwise, keydown or keypress
event to look for the 'enter' key and take whatever action you need.

A question came up at work from one of our clients about forms on their

The data from these forms are processed by a PHP script and if all goes

Other times it is not. The client would like to ensure the data remains, as

Hi,
I have a strange behavior when using IExplorer over FireFox.
There is an html form that asks for the name of a city and has
a dedicated field for that with a submit button next to it.
In IExplorer, if I hit return instead of clicking the button,
the PHP query on MySQL fails when reaching the mysql_fetch_object
function. It's ok if I click the button.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
