Ok - so you're using a keyboard wedge.

I can't tell you exactly why, but obviously ^G does not work as Ctrl+G in a string control (if you try to type it in manually it doesn't work either).

Is it possible to configure this end-character?

[JTAG]

NO!!!.

I must to solve this .i'm sure there is a way to handle this. if in VB and dos i can see the end of the tail

i'm sure that in labview there is a way to do that.

Maybe this problem exists, because Ctrl+G is a fixed shortcut in LV (find next element e.g. if you searched for all instances of a vi).

So you basically have no problems to "acquire" the barcode - it's just this character.

I'd suggest you to start a new thread, concentrating on this (for instance "0x07 not displayed in string control") or you could also contact your local NI office.

Sorry for not being able to give you a more positive answer.

Put a probe on the 'Plat Mods' wire and on the 'char' wire then run the VI

You are not getting a 'CTRL G' with the keyboard but CTRL then character 103
You have set the numeric data type constant to HEX which makes it a little more fun, so that 103 decimal = 67 hex
The key code thus seems to work.

Hope this helps figure out why and what the problem is.

Thank's for your time man.

Further,
If you want to enter a 07 character use the ALT key then type 007 from the numeric keypad

Don't forget to change your code to detect a hex 7

I must correct my last post.

If you wire an U8 array, where one field contains 0x07 to the Byte Array to String function, it is displayed. But as this character is sent to LV from the keyboard input, it may conflict with the shortcut mentioned.
