Generating DLL files under VS2010 environment

VS2010 Build DLL file 1, create a new Win32 project, select the DLL project, such as:

2, add header files and CPP files separately
#ifndef Lib_h
#define Lib_h
extern "C" int _declspec (dllexport) Add (int x,int y); External functions declared as C-compile, link-way
#endif # include "StdAfx.h"
int add (int x,int y)
{
return x+y;
}3, create a new Win32 console project, add the header file, and then write the following code in the main function:
#include "stdafx.h"
using namespace Std;
int _tmain (int argc, _tchar* argv[])
{
typedef int (*lpaddfun) (int,int);//macro defines function pointer type
HINSTANCE Hinst=null;
Lpaddfun Addfun; function pointers
Hinst=::loadlibrarya ("C:\\users\\administrator\\documents\\visual Studio 2010\\projects\\win32study\\debug\\test _1.dll ");
if (hinst==null)
{
printf ("Load mydll. DLL fail!\n ");
return 0;
}
Else
{
Addfun= (Lpaddfun) GetProcAddress (HInst, "add");
if (addfun!=null)
{
int Result=addfun (2,3);
cout<<result<<endl;
GetChar ();
}
}
FreeLibrary (HInst);
return 0;
}4, running results such as:
