creating and printing 2d barcode with labview

[gehill]

I had to create a 2d barcode in my application. I use an active-X-element witch generate the code. The problem is, that i can't print the code. The Active-X-methode needs a device context as a handle. We tried the createDCA() function (gdi32.dll), but it didn't work.
Is there someone who have an 2d-barcode generator for useing in LabVIEW? Or have someone VI's for generating a printer-handle?

Hello Gehill,

Thank you for contacting National Instruments.

Am I correct in assuming that you are trying to print from the activeX object? If so, you might want to contact the developer of your object to find out if you can and how to print.

In answer to your last two questions; no, National Instruments does not have any 2d-barcode generators. Perhaps another forum user will be able to help you there.

If you would like, you can post your VI including the activeX object and I will see if I can work through the problem.

Have a great day.

Well first off, replying to an 8 year old thread is not usually the best way to start but, we can still help.

a few question first.

• Are you using a printer? what kind?
• What 2D Barcode format will you use? there are several

Perhaps you can use the attached as a starting point.

You will also need the .DLL from installing:

Hello PCARDINALE...

Can you send me the VI for labview 11.01 version?

I don't have version 12 yet....

Thank you very much for your support!

I can see 5 VI's inside the Zip file.... I'm assuming that the one I need is the Barcode_generator VI.....correct?

Saludos!

why did you not enclude the dependant dll?  or at least a link to it?

If you have access to the internet at the time you need to generate the QR Code, you can use this VI from the LAVA forums to call the Google API.

No DLL required.
