C++-DLL开发环境搭建

一.VisualStudio下载WindowsSDK

二.创建vcxproj文件

<?xml version="1.0" encoding="utf-8"?> <Project DefaultTargets="Build" ToolsVersion="15.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup Label="Globals"> <ProjectGuid>{0b831b6d-7f3d-46d6-acf2-db806005b325}</ProjectGuid> <Keyword>DynamicLibrary</Keyword> <RootNamespace>BLDllPlus</RootNamespace> <DefaultLanguage>zh-CN</DefaultLanguage> <MinimumVisualStudioVersion>14.0</MinimumVisualStudioVersion> <WindowsTargetPlatformVersion>10.0.22621.0</WindowsTargetPlatformVersion> <WindowsTargetPlatformMinVersion>10.0.17763.0</WindowsTargetPlatformMinVersion> <ApplicationTypeRevision>10.0</ApplicationTypeRevision> </PropertyGroup> <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|x64'" Label="Configuration"> <ConfigurationType>DynamicLibrary</ConfigurationType> <UseDebugLibraries>true</UseDebugLibraries> <PlatformToolset>v143</PlatformToolset> </PropertyGroup> <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|x64'" Label="Configuration"> <ConfigurationType>DynamicLibrary</ConfigurationType> <UseDebugLibraries>false</UseDebugLibraries> <WholeProgramOptimization>true</WholeProgramOptimization> <PlatformToolset>v143</PlatformToolset> </PropertyGroup> <ItemGroup Label="ProjectConfigurations"> <ProjectConfiguration Include="Debug|x64"> <Configuration>Debug</Configuration> <Platform>x64</Platform> </ProjectConfiguration> <ProjectConfiguration Include="Release|x64"> <Configuration>Release</Configuration> <Platform>x64</Platform> </ProjectConfiguration> </ItemGroup> <ItemGroup> <ClCompile Include="dllmain.cpp" /> </ItemGroup> <Import Project="$(VCTargetsPath)\Microsoft.Cpp.Default.props" /> <Import Project="$(VCTargetsPath)\Microsoft.Cpp.props" /> <Import Project="$(VCTargetsPath)\Microsoft.Cpp.targets" /> </Project>

三.创建DllMain函数

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; }
