wxpython wx.windows的API

wx.Window is the base class for all windows and represents any visible object on screen. All controls, top level windows and so on are windows. Sizers and device contexts are not, however, as they don't appear on screen themselves. Please note that a

Python2.7在Windows下CMD编码为65001/utf-8时print报错[Errno 0]/[Errno 2]

使用python2.7处理unicode的字符串,环境变量已设置PYTHONIOENCODING为utf-8,cmd编码为utf-8时print unicode字符串会报错[Errno 0]或[Errno 2] #coding:utf-8 import os os.system("chcp 65001") a = u"你好こんにちは" print a 此时会报错,如果字符串只含ASCII字符就不会报错,如果cmd用其他编码则可能输出乱码但不会报错 经查这是windo

利用Python脚本管理Windows服务

Windows服务常用的功能就是启动服务,关闭服务,重启服务和查询服务运行状态,其中查询服务运行状态是其他三种操作的基础. 本文中提到的使用Python脚本管理Windows服务实际上是调用win32serviceutil模块,此模块来自pywin32包,此模块本身有管理服务的功能,有兴趣的可以去阅读它的部分源码. 本脚本存在的目的是为了熟练Python的语法和基本操作,Windows下有更好的命令行工具来管理服务,如sc.Powershell等.通常命令行工具的执行速度要比services.m

Windows 消息机制详解

总的来说: MSG包括: 窗口句柄,指示MSG发送的目的窗口 消息标识 lPARAM.wParam 发送时间 发送时的鼠标位置   关于消息队列: Windows系统有一个系统消息队列 每个线程都有一个自己的消 息队列(由于发送消息MSG需 要提供一个窗口HWnd,而基 本有窗口的线程,都是UI线 程),因此基本上如果线程使用了GDI函数,则windows给该线程分配一个线程消息队列,这个消息队列负责该线程的所有窗口的消息.   所有的窗口都有自己的句柄(HWND),消息被发送时,这个句柄就已经
