Python win32gui.PostMessage 无法工作

Question

我想关闭我找到的 window，这是代码..

import ctypes
import win32gui, win32con, win32api

EnumWindows = ctypes.windll.user32.EnumWindows
EnumWindowsProc = ctypes.WINFUNCTYPE(ctypes.c_bool, ctypes.POINTER(ctypes.c_int), ctypes.POINTER(ctypes.c_int))
GetWindowText = ctypes.windll.user32.GetWindowTextW
GetWindowTextLength = ctypes.windll.user32.GetWindowTextLengthW
IsWindowVisible = ctypes.windll.user32.IsWindowVisible

titles = []
user32 = ctypes.windll.user32
ole32 = ctypes.windll.ole32

def foreach_window(hwnd, lParam):
    if IsWindowVisible(hwnd):
        length = GetWindowTextLength(hwnd)
        buff = ctypes.create_unicode_buffer(length + 1)
        GetWindowText(hwnd, buff, length + 1)
        titles.append(buff.value)
        if (buff.value == '123.txt'):
            print('I got u...')
            win32gui.PostMessage(hwnd,  win32con.WM_CLOSE,  0,  0)
    return True

EnumWindows(EnumWindowsProc(foreach_window), 0)

但是出现错误，

win32gui.PostMessage(hwnd,  win32con.WM_CLOSE,  0,  0)
TypeError: The object is not a PyHANDLE object

我该如何解决？谢谢

ctypes 和 win32 hwnds 不一样。尝试使用 ctypes.PostMessage:

关闭应用程序

PostMessage = ctypes.windll.user32.PostMessageA

和

win32gui.PostMessage(hwnd,  win32con.WM_CLOSE,  0,  0)

Python win32gui.PostMessage 无法工作

Python win32gui.PostMessage can't work
