I am using a barcode scanner that insert the barcode in any text field activated. I want to put this barcode into database, I tried so many events but all of them fire after reading first char only from barcode. So i though of using array with a fixed length and insert the chars into it but I don't know which event to use. Can you help me?

The scanner is very easy to use you just click the button and the barcode will appear on
word file, excel sheet even if you were renaming your file or your folder will appear in name field.

I used these events (textchanged, keypress, keyup)

I want to insert barcode into database without clicking any button in the form. Just reading the string and insert.
I don't want any code just hints.

Thanks in advance.

As you can see here:
http://www.racoindustries.com/motorola-ds4208-features.htm[^] - the scanner supports OPOS. So I would recommend using the OPOS API[^]

In my experience it's simple and reliable :)

Solution 1

Most barcode scanners I know of can be configured to send a special character (e.g. a line break CRLF) after reading a barcode. You could use any event (textchanged, keypress) and then check if that character was received. This should allow you to send the text to the database after the string was completely entered into the textbox.

how can i configure it using code or it is within its configuration

BobJanova 14-Apr-11 7:22am

It will probably be an option in the scanner's driver or a configuration file, if it does not send something (an Enter probably) by default.

Normally you get a small booklet with the scanner where you can scan some codes that define the behaviour of the scanner.
