关于测试一个windows动态链接库的问题；请教各位大侠！

有如下程序：

// test1.cpp : Defines the entry point for the console application.

//

#include "stdafx.h"

#include <windows.h>

int main(int argc, char* argv[])

{

printf("Hello World!\n");

typedef int(*pSleep)(long sleepTime);

HINSTANCE hDLL;

pSleep psleep;

HDLL=LoadLibrary("D:\\广东省建设银行\Sleep\sleep\Debug\sleep.dll");//加载动态链接库sleep.dll文件；

psleep=(pSleep)GetProcAddress(hDLL,"sleep");

for (int i=0;i<3;i++){

printf("Sleeping for %d seconds\n", i);

psleep(300);

}

FreeLibrary(hDLL);//卸载MyDll.dll文件;

return 0;

}

编译是为何报这个错：

D:\广东省建设银行\Sleep\test1\test1.cpp(15) : error C2440: '=' : cannot convert from 'struct HINSTANCE__ *' to 'int'

This conversion requires a reinterpret_cast, a C-style cast or function-style cast

Error executing cl.exe.
