QT中 error: ‘CHAR’ was not declared in this scope,还有就是模拟乒乓球源码UpdateData();也出现错误
Qt中没有默认的CHAR,你说你是从MFC转来的,那么在MFC里CHAR就是最新飞蛾源码char,所以你把CHAR改成char吧。汝州宜阳源码出售
你追问楼上的问题:error: cannot convert ‘QString’ to ‘const char*’ for argument ‘2’ to ‘char* strcpy(char*, const char*)’
上面这个错误是第7行 strcpy(filename,QString(m_NameValue));
strcpy是对char*操作的,你的第二个参数是QString啊,所以要改成
strcpy(filename,QString(m_NameValue).toLatin1());
其中QString(m_NameValue).toLatin1()的作用是:以参数 m_NameValue 构造QString对象,然后调用函数 QString::toLatin1() 将构造的对象转换为C风格字符串,也就是char *的类型,以符合strcpy函数。
QString 类似于C++的鄂州源码名片购买string 非常好用,你可以多看帮助文档。
建议你将QT写成Qt以免误解。黑马追踪指标源码
