I use C++Builder6 and create 32bit applications. Do you have version of Barcode for C++ for it?
I downloaded Aspose.BarCode for Cpp 19.9. I can see inside just 64bit lib and dll. I added lib into my project but I have error via compile [Linker Error] ‘ASPOSE.BARCODE.CPP_VC141X64.LIB’ contains invalid OMF record, type 0x21 (possibly COFF)
Aspose.BarCode for C++ supports only x64 version and requires Platform Toolset 141. In this way VS2017+ and Visual Studio Code are only supported.
However you can solve this problem if you create .COM exe hosting application and use .COM calling. Also you can use .Net version with .COM marshaling.
