error C2065: 'hdll' : undeclared identifier

[泡芙女孩儿]

刚刚编写了一个动态链接库的实例，却出现这样的错误，求高手指教。
#include "stdafx.h"
#include "a.h"
#include "aDlg.h"
__________________________________________________
___________________________________________________
void CADlg::OnButton1()
{
// TODO: Add your control notification handler code here
hdll=loadLibrary("text.dll");
if(hdll)
{
typedef void(*PROCTYPE);
PROCTYPE myprint=(PROCTYPE)GetProcAddress(hdll,"print");//得到函数地址
(*myprint)();
}
FreeLibrary(hdll);//释放库
}

aDlg.obj - 4 error(s), 0 warning(s)



若是添加链接库的头文件#include "text.h"会出现这样的错误，求教哪位大侠能帮忙分析一下，给出正解。
#include "stdafx.h"
#include "a.h"
#include "aDlg.h"
#include "text.h"

1、hdll没有定义就直接使用了；
2、loadLibrary前面的l需要大写；
3、需要#include<windows.h>。
