我想結束我發現窗口,這裏是代碼..Python的win32gui.PostMessage不能工作

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) 

但錯誤發生,

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

如何解決它呢? 謝謝

ctypes和win32 hwnds是不一樣的。嘗試使用ctypes.PostMessage關閉應用程序:

PostMessage = ctypes.windll.user32.PostMessageA 

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

感謝,讓我試試。 –
