I am trying to read a USB barcode scanner configured as a keyboard input in Labview. I initialize the keyboard input and wait for the scan in a while loop to read the scanner input. I am able to read the characters but the keyboard does not return the barcode as is printed. It returns 0's in between characters and also misses some characters. So, it is not consistent on what it reads each time. have any of you had a similar problem, your help is appreciated.
Along with this, you seem to want to do things the hard way. Have you tried a simple string control for entering the scan? Here's a a simple VI. The front panel Stop control is set for a 'Return' toggle in the Key Navigation menu so that the while looop stops as soon as the bar code scanner sends a return character. It's in 8.0.

PR hasn't been on the forums since 2008. I doubt he is still following.
If you have a particular issue, ask about it in a new thread. But first search the forums because there are many other threads that discuss keyboard wedge type scanners.
I just got the VI and I have aquestion: is there any way to have the string control active, when I run the VI ? As it is now, I must click it, in order to make it ready to get the data I read from the barcode.
