My 5. I immediately found it, too. But this is C#, OP asks about C++.

Good link, a 5 - event if it's c#, doesn't seem to be many available options out there

Thank you Espen.

Solution 2

So far, I did not find for C++, too.
However, you still can use C# solution (Open Source QRCode Library[^], E$w@e found it, too), because there is a nice way to export methods from .NET Assembly to unmanaged (without using COM!), and then you would use the resulting library in C++. Many think it's not possible, but this is not true.

Please see my other Answer: loading C# DLL in MFC[^].

I'll understand if you cannot accept this answer. In this case, keep searching, Google is your friend.

Good Suggestion & Solution. Have 5 +

Thanks. And I tested the technique.

Good link, a 5 - even if it's c#, doesn't seem to be many available options out there, and this provides one option for accessing the functionality from c++

Sergey Alexandrovich Kryukov 8-Feb-11 19:18pm

Thank you, Espen.
You see, this time you agree with the value of direct export of managed method to unmanaged, despite your concern you expressed in the other comment (I recently replied). Again, it depends on the purpose and can be a matter or discussion.

I did not find any so far, did you?
My idea is to use available .NET library written in C# and use it in your C++ using the export method I pointer out in my Answer.
