BAR Code QR Code Problem

[alialiali]

Dear All,
I am doing a project. I need to detect QR Code and Bar code. The issue I am having is that i cannot detect them simultaneously. I press one button for Bar Code, it gets scanned and detected, and then I have to press another button for QR code, then it gets scanned and detected. As a result, I cannot get them saved in one row. I get data like the picture attached. The problem in this is that the barcode represent student ID, and when i search the data base using barcode no. , I dont get anything, because that row has got no QRCode. I want them to appear in one row. PLEASE HEL ME! Thx.

Hi ali,

well, you need to write them in one line instead of two…

You should not use "default if unwired" output tunnels on your case structures when you don't want to write empty strings into your table!

Dear Gerd,

Thank you for the reply. Yes, iknow that I need to write them in one row/line and that is the problem. Both the codes are not detected at one time, so both the codes get acquired in different rows. I want of of them in one line! Thx.

Hi Qasim,

as said before:

DON'T USE "default if unwired tunnels" in your case structures!

Instead you should always output the last read result…

I will try it and get back to you soon. thanks alot!

Dear Sir

i am working with Mr Qasim on this project

what do u mean by the default unwired sir..

Actually when i didnt let any wire unwired. when the true case is done and i press false case

this also i wired

can u please be more specific what u mean with default unwired.

shall we share the VI

Hi zah and Qasim,

this is an example of what I'm talking about:

Btw: you should clean up your VI too. Using the AutoCleanup button might give a start!

[zah12]

ohh okay, we should not use this.. but many places i used this to wire

should i try to redo it one by one.

i use the auto clean up. what i saw when i use that is like the case structure kept changing places and when i run my VI. again the same problem

i did try also to remove the default i use. i attach the snapshot of it.

in the true case, i remove the default like in the attach sec 1.

then when i went to the false case, the wire is hanged. i dont know with what i have to wire it

like in the attach of sect 2

Hi zah,

you have to provide a value to the tunnel in each case!

As said before in message #4:

Instead you should always output the last read result…

[zah12]

okay

i see

sir what do u mean by that  ' Instead you should always output the last read result…

output the last read.. ( last read meaning)

meaning in the false condition , i should put an output as wat?

an example will be really apreciated sir
