Python 2.6帮助中的ctypes [英] ctypes in Python 2.6 help

问题描述

我似乎无法使该代码正常工作，给我的印象是我做得正确。

I can't seem to get this code to work, I was under the impression I was doing this correctly.

from ctypes import *


kernel32 = windll.kernel32

string1 = "test"
string2 = "test2"

kernel32.MessageBox(None,
                       string1,
                       string2,
                       MB_OK)

**我尝试将其更改为MessageBoxA，如下所示**
**错误I获取:: **

** I tried to change it to MessageBoxA as suggested below ** ** Error I get :: **

Traceback (most recent call last):
  File "C:\<string>", line 6, in <module>
  File "C:\Python26\Lib\ctypes\__init__.py", line 366, in __getattr__
    func = self.__getitem__(name)
  File "C:\Python26\Lib\ctypes\__init__.py", line 371, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))
AttributeError: function 'MessageBoxA' not found

推荐答案

MessageBox是在user32中定义的，而不是kernel32，您也没有定义了MB_OK
，因此请改用此

MessageBox is defined in user32 not kernel32, you also haven't defined MB_OK so use this instead

windll.user32.MessageBoxA(None, string1, string2, 1)

我也建议使用 python win32 API 值得关注，因为它具有所有常量和命名函数

Also I recommend using python win32 API isntead of it ,as it has all constant and named functions

编辑：我的意思是使用

from ctypes import *

kernel32 = windll.kernel32

string1 = "test"
string2 = "test2"

#kernel32.MessageBox(None, string1, string2, MB_OK)
windll.user32.MessageBoxA(None, string1, string2, 1)

可以使用win32 api做同样的事情

same thing you can do using win32 api as

import win32gui
win32gui.MessageBox(0, "a", "b", 1)
