If you send your barcode data to a string control and then set the string control to display HEX data, you should be able to see the codes....

Right click on the front panel string indicator control to get the option to display the HEX codes.

Don't forget to check that the barcode type you are using supports the code you think that you have.

Hi

You could use the "Strin to Bytearray" function. This allows you to compare each character, although it may not be displayed in the string control.

Hope this helps.

Then I'd say it is not there.

How do you get the data? Did you check with another tool if it works?

See the attach file.

As you may have seen in my posts, I use LV7.0.

So could you repost your vi as LV7.0 (File>>Save with options>>Save for previous)?

[JTAG]

see the attached file, also if i read the barcode into dos, i can see at the end the ^G.

I strongly assume you don't read the barcode with the posted vi.

I further assume you have a barcode scanner, which is connected to a computer over rs232 ore something else. If there really is ^G at the end of the data you should receive, there won't be either 0x47 or 0x67, but 0x7 instead.

So tell us more about the whole system.
