Dll2.dll Apr 2026

This example creates a simple DLL that exports an addition function and a class method. 1. Dll2.h (Header File)

#pragma once #ifdef DLL2_EXPORTS #define DLL2_API __declspec(dllexport) #else #define DLL2_API __declspec(dllimport) #endif // Exported function extern "C" DLL2_API int AddNumbers(int a, int b); // Exported class class DLL2_API Dll2Class { public: Dll2Class(void); int MultiplyNumbers(int a, int b); }; Use code with caution. 2. Dll2.cpp (Source File) This file contains the actual logic. Dll2.dll

#include "pch.h" #include BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { switch (ul_reason_for_call) { case DLL_PROCESS_ATTACH: case DLL_THREAD_ATTACH: case DLL_THREAD_DETACH: case DLL_PROCESS_DETACH: break; } return TRUE; } Use code with caution. Key Considerations The use of __declspec(dllexport) is crucial. This example creates a simple DLL that exports
