    Generate QR code in Devexpress can't use lowercase ?

    Can't use lowercase letters in Devexpress to generate QR codes? Or is there a library called that can generate lowercase uppercase QR codes with less error ?

    Perhaps you should provide more information. Also, is this really C# related?

    Microsoft's visual studio has a QR code library? Devexpress is too heavy to run

    I don't think so, that's why tools exist. I posted one that is free and works OK above. I'm sure there are others.

    I read the documentation on the https://www.e-iceblue.com/Knowledgeb...e.BarCode.html net and added the library using Spire.Barcode; into Visual Studio, but got the error below, do you know how to fix this error? library you see attached file https://www.mediafire.com/file/53zu0...rcode.dll/file

    warning error:

    The currently targeted framework ".NETFramework,Version=v4.0,Profile=Client" does not include "System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which the referenced assembly "Spire.Barcode, Version=1.2.5.21040, Culture=neutral, PublicKeyToken=663f351905198cb3, processorArchitecture=MSIL" depends on. This caused the referenced assembly to not resolve. To fix this, either (1) change the targeted framework for this project, or (2) remove the referenced assembly from the project.

    Are you kidding? The error message that you copied and pasted specifically states "To fix this..." and then provides instructions. How about you read that and do what it says?

    I already understand and it's rich you pretending I don't. The error message tells you what the issue is (the Framework you're targeting doesn't include a required assembly) and what to do about it (target a Framework that includes that assembly). I'm not seeing what exactly is not to understand but you've managed it.
