from ctypes import *
fileName="TestDll.dll"
func=cdll.LoadLibrary(fileName)
#print func.HelloWorld()
func.HelloWorld()

(Lib.h)
#ifndef LIB_H
#define LIB_H
extern "C" int __declspec(dllexport)add(int x, int y);
#endif
(Lib.cpp)
#include "Lib.h"

int add(int x, int y)
{
return x + y;
}

编译为TestDLL.dll。
然后建立一个Python文件TestDLLMain.py测试：
from ctypes import *
dll = CDLL("TestDLL.dll")
print dll.add(1, 1)

结果：2

简单得不能再简单了！

from ctypes import *
fileName="LRDllTest.dll"
func=cdll.LoadLibrary(fileName)

import win32com.client
#usedll=win32com.client.Dispatch("Memory.dll")

搞定了几个东西
1,取得鼠标位置,get_mpos()
2,移动鼠标,set_mpos()
3,鼠标左键点击,move_click()
4,键盘输入(部分搞定,那个scancode还不明白是啥意思,为什么0x99输出的是字符'p'???)
代码如下
