SendKeys 在线程中运行 2 次后失败

Python 和 SendKeys

import SendKeys, threading, pyHook, pythoncom
class Auto(threading.Thread):
    def run(self):
        SendKeys.SendKeys("{ENTER}",pause=0.1);
        print('Sent');
        exit();
def OnKeyboardEvent(event):
    if event.Ascii == 22:
        Auto().start();
    return True
        
hm = pyHook.HookManager()
hm.KeyDown = OnKeyboardEvent
hm.HookKeyboard()
pythoncom.PumpMessages()

由于某种原因，该程序在运行两次后失败，我不知道原因是什么。当您注释掉 SendKeys 部分时，程序运行正常，因此肯定是发送键有问题。

[编辑]另外，为了澄清，在 for i in range(0,100) 中运行 SendKeys.SendKeys(...) 是有效的，所以我认为这与线程有关。我以前从未编写过线程。另外，这只是一个复制问题的模型示例。

我在 windows 7、python2.6 上运行

[编辑]此外，程序不会“失败”，它只是冻结（该函数根本不运行，它只是坐在那里）

Python and SendKeys

import SendKeys, threading, pyHook, pythoncom
class Auto(threading.Thread):
    def run(self):
        SendKeys.SendKeys("{ENTER}",pause=0.1);
        print('Sent');
        exit();
def OnKeyboardEvent(event):
    if event.Ascii == 22:
        Auto().start();
    return True
        
hm = pyHook.HookManager()
hm.KeyDown = OnKeyboardEvent
hm.HookKeyboard()
pythoncom.PumpMessages()

For some reason this program fails after running it exactly two times, I have no idea what the cause for this is. When you comment out the SendKeys part the program runs fine, so it has to be a problem with send keys.

[edit] Also, to clarify, running SendKeys.SendKeys(...) in a for i in range(0,100) works, so I assume it's something to do with the thread. I've never programmed threads before. Also this is just a mockup example to replicate the problem.

I'm running on windows 7, python2.6

[edit]Also, the program doesn't 'fail' it simply freezes (the function isn't run at all, it just sits there)

看来SendKeys是线程安全的。以下代码适用于 Vista - Python 2.6

class Auto(threading.Thread):
    def run(self):
        SendKeys.SendKeys("#",pause=0.1);
        print('Sent');
        exit();

for i in xrange(30):
    Auto().start()

也许问题来自于 PyHook 或 Windows PumpMessage 机制的一些干扰。您是否尝试过将 SendKeys 部分放在不同的进程中而不是放在不同的线程中？

我希望它有帮助

It seems that SendKeys is thread safe. The following code works on Vista - Python 2.6

class Auto(threading.Thread):
    def run(self):
        SendKeys.SendKeys("#",pause=0.1);
        print('Sent');
        exit();

for i in xrange(30):
    Auto().start()

Maybe the problem comes from some interferences with PyHook or the Windows PumpMessage mechanism. Have you tried to put the SendKeys part in a different process rather than in a different thread?

I hope it helps
