问题描述

我想在另一个类中使用NameDlg.h中标识的变量，但我不知道该怎么做.
我在Dlg.cpp文件中指向了"this"(！)，但是我不能使用它.
我的代码在这里:
(CMynameDlg *)指针)-> My_variable

编译错误为:未声明的标识符"

请帮帮我！

推荐答案

如果在NameDlg.h中声明了变量 ，则必须在Dlg.cpp中包含这样的头文件. br/> 但是，您实际上想做什么?您知道，您不应该直接公开变量，最好将变量访问器定义为某个类的公共方法.
:)

If your variable is declared in NameDlg.h then you have to include such header file inside Dlg.cpp.
However, what do you want to do really? You know, you shouldn''t expose directly variables, it would be better to define variable accessors as public methods of a some class.
