环境: VC++6.0
步骤:
1.建立一个WIN32 DYNAMIC-LINK LIBRARY工程,编写CPP文件,文件内容例如:
1 #include "stdafx.h" 2 #include "windows.h" 3 #include "dll.h" 4 BOOL APIENTRY DllMain( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) 5 { 6 return TRUE; 7 } 8 extern"C"_declspec(dllexport)int sum(int a, int b) { return a+b; }
2.记得编写头文件,在本次事例中,头文件为dll.h,内容:
1 extern"C"_declspec(dllexport) int sum(int a,int b);
3.进行编译连接,本过程可能回有点(相当)曲折.编译连接OK,生成*.dll *.lib 这两个文件便可用了.
(静态调用)测试:
创建一个WIN32 CONSOLE APPLICATION,编写CPP代码例如:
1 // dllTest.cpp : Defines the entry point for the console application. 2 // 3 4 #include "stdafx.h" 5 #include <stdio.h> 6 extern"C"_declspec(dllexport) int sum(int a,int b); 7 #pragma comment (lib,"dll") 8 int main(int argc, char* argv[]) 9 { 10 printf("%d ",sum(2,4)); 11 12 return 0; 13 }
编译连接即可.(记得将*.LIB *.DLL复制到测试的工程目录下)
(动态调用)测试:
1 #include "stdafx.h" 2 #include <Windows.h> 3 #include <stdio.h> 4 5 typedef int(*dllSum)(int,int); 6 int main(int argc, char* argv[]) 7 { 8 HMODULE hModule=LoadLibrary("dll.dll"); 9 dllSum sum=(dllSum)GetProcAddress(hModule,"sum"); 10 11 printf("%d ",sum(2,22)); 12 return 0; 13 }
