简单版小说搜索阅读（64位程序）
本帖最后由 htpidk 于 2020-7-18 15:48 编辑今天发现之前写的一个64位小说搜索与阅读程序，代码写的比较挫，不过把写的过程中遇到的一些坑注释出来了，大家以后可以避免这种情况，程序用到了miniblink（github上找的到）和我自己写的一个SDK的界面库，也不算界面库，只是简单的封装了12种常用的组件

/*
不能这样赋值，经过反汇编查看，m3.str(1)和m3.str(2)生成的是一个string临时对象，这个对象在调用完c_str()就调用析构函数
销毁了，导致c_str()返回的字符串指向了乱码，string类对象c_str()返回的字符串指针是直接指向内部数据的，不是new几个char内存
来存放的，string类对象改变后，原来用c_str()返回的字符串指针指向的内容也会改变

C++ ，哈哈。用这个写小说搜索程序，有劲。 我要做伸手党。。 阅读达人 可以把界面优化一下还是不错的 佩服 C++写这个不累吗？？
