#include "stdio.h"

typedef double ( * lpAddFun)(double,double);

int main()

{

    HINSTANCE hDll;    

lpAddFun addFun;  

double result;

    hDll = LoadLibrary("..\\add.dll");

if (hDll != NULL)

{

  addFun = (lpAddFun)GetProcAddress(hDll,"add"); 

  if(addFun!=NULL)

  {

      result = addFun(5,3);    

   printf("%f\n",result);

  }

  FreeLibrary(hDll);

} 

return 0;

}

这样LV生成的DLL就能在VC下调用了。
