ATL dll可以将类对象作为参数吗? [英] can ATL dll take a class object as parameter?

问题描述

我有一个ATL dll项目和其中的两个类(classA，classB). ClassA将classB作为参数.

i have an ATL dll project and two classes (classA,classB) in it. ClassA takes the classB as parameter. In ATL is it possible and how?

推荐答案

为什么应该不可能? :)

Why should it be impossible ? :)

class B;

class A
{
...
public:
  A(B* pB);
...

当您必须通过接口传输类实例时-
您可以定义类似TakeData(IStream* pStream)的函数:)

调用者可以创建与COleStreamFile，
相关联的IStream 将任何对象序列化到文件中
并将分离的IStream*传递给接口函数:)

当然，服务器必须知道所运输的对象
及其序列化方法...:)

When you will have to transport class instances by an interface -
you could define a function like TakeData(IStream* pStream) :)

The caller could create an IStream associated with COleStreamFile,
serialize any object(s, collections) in to the file
and pass the detached IStream* to the interface function :)

Of course the server must know the trasported objects
and their serializing methods... :)
