pythonpostmessage_请教：Python如何通过句柄（handle）发送和接收消息，样例取得的handle为啥不一样！...

如题&＃xff0c;想通过 handle 让别程序关闭我编译为 exe 的程序,

原理是通过向 handle 发送关闭信号&＃xff0c;程序检测到&＃xff0c;就执行相关代码&＃xff0c;顺便想看看一个程序是如何通过句柄控制其他程序的&＃xff0c;暂时不使用其他进程间通讯技术

hinst &＃61; win32gui.GetModuleHandle(None)

hWindow &＃61; pywintypes.HANDLE()

这两个获取的句柄不一样&＃xff0c;使用 spyxx 获取句柄后&＃xff0c;手动发送信号也没反应&＃xff0c;不知道是什么原因&＃xff0c;在此请教&＃xff0c;不胜感激。

代码如下

# -*- coding: utf-8 -*-

import time,pywintypes

import threading

from ctypes import *

from ctypes.wintypes import *

import win32con,win32gui

user32 &＃61; windll.user32

class ListenThread(threading.Thread):

def __init__(self):

threading.Thread.__init__(self)

def run(self):

#保存线程 ID

# self.ident &＃61; threading._get_ident()

msg &＃61; MSG()

#创建线程消息队列

user32.PeekMessageW(byref(msg), None, win32con.WM_USER,win32con.WM_USER, win32con.PM_NOREMOVE)

self.hinst &＃61; win32gui.GetModuleHandle(None)

print(self.hinst)

hWindow &＃61; pywintypes.HANDLE()

print("hWindow:", hWindow)

#消息循环

while True:

user32.GetMessageW(byref(msg), None, 0, 0)

if msg.message &＃61;&＃61; win32con.WM_QUIT:

print (&＃39;thread quit&＃39; )

break

elif msg.message &＃61;&＃61; win32con.WM_USER &＃43; 779:

print( &＃39;I get it&＃39; )

else:

print("ddd")

time.sleep(1)

user32.TranslateMessage(byref(msg))

user32.DispatchMessageW(byref(msg))

print (&＃39;create thread&＃39; )

hThread &＃61; ListenThread()

print (&＃39;start thread&＃39;)

hThread.start()

for i in range(5):

time.sleep(1)

user32.PostMessageW(hThread.hinst, win32con.WM_USER &＃43; 779, 0, 0)

print ("ddddd")

else:

user32.PostThreadMessageW(hThread.hinst, win32con.WM_QUIT, 0, 0)
