用LoadLibrary和GetProcAddress函数调用dll的代码有问题，希望高手指点（谢谢）!

请高手指点程序有何问题，我做了一个dll文件想用显示的方式调用,就是用LoadLibrary和GetProcAddress函数实现，可是运行总是出错。
程序代码如下：
//Dll_Test.cpp 生成Dll_Test.dll
#include "stdafx.h"
#include "Dll_Test.h"
int Max(int a, int b)
{
if(a>b)
return a;
else
return b;
}
BOOL APIENTRY DllMain( HANDLE 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;
}

//Test_GetMax.cpp
#include "stdafx.h"
#include <stdio.h>
#include <afxwin.h>
#include <afxext.h>
#include <afxdisp.h>
#include <afxdtctl.h>
int main(int argc, char* argv[])
{
typedef int (CALLBACK* LPFNDLLFUNC)(int ,int);
HINSTANCE hDLL;
LPFNDLLFUNC lpfnDllFunc;

hDLL = LoadLibrary("Dll_Test.dll");
if (hDLL != NULL)
{
lpfnDllFunc = (LPFNDLLFUNC)GetProcAddress(hDLL, "Max");
if (!lpfnDllFunc)
{
FreeLibrary(hDLL);
}
else
{
printf("已经找到函数");
int a;
a = lpfnDllFunc(1,2);
printf("返回直:%d",a);
}
}
return 0;
}
