DLL_project 目錄有 dll.h 和 dllmain.cpp 檔

流程: 宣告 → 實作

dll.h 介面宣告
原始碼:
#ifndef _DLL_H_
#define _DLL_H_

#if BUILDING_DLL
#define DLLIMPORT __declspec(dllexport)
#else
#define DLLIMPORT __declspec(dllimport)
#endif

extern "C" __declspec(dllexport) void HelloWorld(void);
extern "C"{
   __declspec(dllexport) double AddNumbers(double a, double b);
}

#endif


dllmain.cpp 實作
原始碼:
/* Replace "dll.h" with the name of your header */
#include "dll.h"
#include <windows.h>
#include <iostream>

extern "C" __declspec(dllexport) void HelloWorld(){

MessageBox(0, "Hello World from DLL!\n","Hi",MB_ICONINFORMATION);
}
extern "C" __declspec(dllexport) double AddNumbers(double a, double b){

return a+b;
}


說明:
.cpp 編譯完成後目錄下即會產生 .dll 檔
