C++builder 二维码生成源码， 具体源码在QR_Encode.h QR_Encode.cpp中， main.cpp中是具体使用方法， void __fastcall TForm1::Button1Click(TObject *Sender) { pQR_Encode=new CQR_Encode(); int nLevel =ComboBox1->ItemIndex;//纠错等级 int nVersion =StrToInt(ComboBox2->Text);//版本 bool bAutoExtent =true;//是否自动扩展 int nMaskingNo = StrToInt(ComboBox3->Text);//掩码模式 AnsiString strEncodeData;//memo中的编码字符 strEncodeData=Memo1->Text; int i, j; int size=3; //修改放大倍数

本文详细描述在c++builder（xe10.2.2tokyo）下如何调用jsoncpp实现json报文的打包与解析，有源代码+详细文档，绝对超值。（同一个世界，同一个梦想，交流学习C++Builder XE10，传承c++builder的魅力！欢迎各地朋友加入我的QQ群484979943,进群密码“BCB”，同时也请将该群号广为宣传，希望能够广集各方高手，共同进步。如需下载开发工具及源代码请加入我的QQ群。）

需要先安装Patch1。 Patch 2 for RAD Studio 10.4 now available This patch addresses a number of issues in RAD Studio 10.4, pertaining to Delphi Compiler, the RAD Studio IDE in general and the new LSP-based Code Insight in particular, plus C++ Builder Android exceptions and some debugger issues. The installation of this patch requires a prior installation of Patch #1 (separately available on GetIt and in the download portal). Installing this patch is recommended for all RAD Studio 10.4 customers. Note that this patch is fairly large to download (around 190 MB).
