Hello all, We've been using XControls in a lot of our application and products. We were thinking to offer some of them in a free toolkit. It's done now. Just follow this link https://decibel.ni.com/content/docs/DOC-21668 to download the package and enjoy the use of these controls in your application. We hope that they would be helpful for you and we really would like to hear feedback from any LabVIEW developer about them (use, LabVIEW integration, ease of implementation,...). Regards.

I've done most of the implementation for supporting QR codes, but I'm having a lot of trouble generating the error correction codes. There are four error correction levels (L, M, Q, and H). 100% of my tested QR codes have the correct error correction for Q and H. About 50% of M codes have the correct error correction codes, and none of the L codes have the correct error correction data. I can't figure out what's wrong with it. Does anyone have experience with generating QR codes? I've looked at some other implementations (MIT license only -- I'd like to stay away from GPL code just in case), but their implementation is very confusing to me.
