python中使用pyhook实现键盘监控的例子
pyhook下载:http://sourceforge.net/projects/pyhook/files/pyhook/1.5.1/
pyhookAPI手册:http://pyhook.sourceforge.net/doc_1.5.0/
以上网站上提供了几个使用的例子,另外安装pyhooks后,也会有一个例子的文件。于是拿来学习了一下,第一次运行时,提示没有pythoncom模块,就安装了pywin32,安装后,可以正常运行,但是会导致机器发卡,特别是中断程序运行后,鼠标会出现一段时间的自由晃动,找了半天原因,感觉主要是事件频率过高,程序会经常卡在pythoncom.PumpMessages()。
网上搜索了半天,看到有一帖子说是pythoncom.PumpMessages(n),n表示延迟时间,于是试着改了下,发现有一定效果,但不明显,后来想是不是因为没有终止程序,才会导致一直很卡呢,于是添加终止程序语句win32api.PostQuitMessage()。结果还算满意。
# -*- coding: cp936 -*- import pythoncom import pyHook import time import win32api t='' asciistr='' keystr='' def onKeyboardEvent(event): global t,asciistr,keystr filename='d://test.txt' wrfile=open(filename,'ab') "处理键盘事件" if t==str(event.WindowName): asciistr=asciistr+chr(event.Ascii) keystr=keystr+str(event.Key) else: t=str(event.WindowName) if asciistr=='' and keystr=='': wrfile.writelines("\nWindow:%s\n" % str(event.Window)) wrfile.writelines("WindowName:%s\n" % str(event.WindowName)) #写入当前窗体名 wrfile.writelines("MessageName:%s\n" % str(event.MessageName)) wrfile.writelines("Message:%d\n" % event.Message) wrfile.writelines("Time:%s\n" % time.strftime('%Y-%m-%d %H:%M:%S',time.localtime())) else: wrfile.writelines("Ascii_char:%s\n" %asciistr) wrfile.writelines("Key_char:%s\n" %keystr) wrfile.writelines("\nWindow:%s\n" % str(event.Window)) wrfile.writelines("WindowName:%s\n" % str(event.WindowName)) #写入当前窗体名 wrfile.writelines("Time:%s\n" % time.strftime('%Y-%m-%d %H:%M:%S',time.localtime())) asciistr=chr(event.Ascii) keystr=str(event.Key) if str(event.Key)=='F12': #按下F12后终止 wrfile.writelines("Ascii_char:%s\n" %asciistr) wrfile.writelines("Key_char:%s\n" %keystr) wrfile.close() win32api.PostQuitMessage() return True if __name__ == "__main__": #创建hook句柄 hm = pyHook.HookManager() #监控键盘 hm.KeyDown = onKeyboardEvent hm.HookKeyboard() #循环获取消息 pythoncom.PumpMessages(10000)

VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.

In VS Code, you can run the program in the terminal through the following steps: Prepare the code and open the integrated terminal to ensure that the code directory is consistent with the terminal working directory. Select the run command according to the programming language (such as Python's python your_file_name.py) to check whether it runs successfully and resolve errors. Use the debugger to improve debugging efficiency.

VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.

VS Code can be used to write Python and provides many features that make it an ideal tool for developing Python applications. It allows users to: install Python extensions to get functions such as code completion, syntax highlighting, and debugging. Use the debugger to track code step by step, find and fix errors. Integrate Git for version control. Use code formatting tools to maintain code consistency. Use the Linting tool to spot potential problems ahead of time.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Golang is more suitable for high concurrency tasks, while Python has more advantages in flexibility. 1.Golang efficiently handles concurrency through goroutine and channel. 2. Python relies on threading and asyncio, which is affected by GIL, but provides multiple concurrency methods. The choice should be based on specific needs.

VS Code is the full name Visual Studio Code, which is a free and open source cross-platform code editor and development environment developed by Microsoft. It supports a wide range of programming languages and provides syntax highlighting, code automatic completion, code snippets and smart prompts to improve development efficiency. Through a rich extension ecosystem, users can add extensions to specific needs and languages, such as debuggers, code formatting tools, and Git integrations. VS Code also includes an intuitive debugger that helps quickly find and resolve bugs in your code.

VS Code is available on Mac. It has powerful extensions, Git integration, terminal and debugger, and also offers a wealth of setup options. However, for particularly large projects or highly professional development, VS Code may have performance or functional limitations.
