Question

我想在我的类线程中使用另一个类对象。
我该如何实施？

我的实现：

.h文件

#pragma once
#include "class_A.h'
#include "class_B.h"

class MyClass
{
public:
    MyClass();
    ~MyClass();
public:
    static DWORD WINAPI _thread_use_another_class_object_(LPVOID lPvoid);
}

.cpp文件

DWORD WINAPI MyClass::_thread_use_another_class_object(LPVOID lPvoid)
{
    DWORD dwCurrentTime = GetTickCount();

    class_A *ca = new class_A;             // I want to use class_A on here.
    ca->bell_action(dwCurrentTime);
    delete ca;

    class_B *cb = new class_B;
    cb->bell_action(dwCurrentTime);
    delete cb;
}

class_A.h

class class_A
{
public:
    class_A();
    ~class_A();
public:
    DWORD bell_action(DWORD type);
    DWORD make_sound(DWORD type);
};

class_A.cpp

DWORD class_A::bell_action(DWORD type)
{
    DWORD sound_wave = type % 670;
    make_sound(sound_wave);

    return 0;
}

class_B与class_A相同

似乎太简单和容易理解了。但是我无法编译它，导致链接错误。
我在Windows 10 RS5 x64上使用VisualStudio 2010 SP1

MyClass.obj : error LNK2019 : unresolved external symbol "public: __thiscall class_A::class_A(void)" ..........
