运行记事本，等待直到它关闭，并且显示内容

我运行的时候出现错误，filename似乎是获取的一个临时文件名，而非我保存的文件名，因此不能read，不能显示出内容。

简介：
本文所有的例均是假设你在使用来自http://timgolden.me.uk/python/wmi/cookbook.html的WMI模块。使用此模块，你可以在Windows系统中去体验下面这些实用的例子。或许你将由此了解到WMI的冰山一角。
下面这些例子，除非有特别说明，均假设你要连接的是当前的机器。如果要连接远程机器，只需要在WMI构造器中指定远程机器名即可：
1 2 | import wmi c = wmi.WMI("some_other_machine") |
注：这都是些完整的例子，你可以直接复制粘贴到一个.py文件里面，也可以复制粘贴到Python命令行交互窗口（原文作者是在Windows2000系统的CMD窗口做的测试）。
实例：
列出所有正在运行的进程
1 2 3 4 5 | import wmi c = wmi.WMI()
for process in c.Win32_Process(): print process.ProcessId, process.Name |
列出所有正在运行的记事本进程
1 2 3 4 5 | import wmi c = wmi.WMI()
for process in c.Win32_Process(name="notepad.exe"): print process.ProcessId, process.Name |
创建一个新的记事本进程然后结束它
1 2 3 4 5 6 7 8 | import wmi c = wmi.WMI()
process_id, return_value = c.Win32_Process.Create(CommandLine="notepad.exe") for process in c.Win32_Process (ProcessId=process_id): print process.ProcessId, process.Name
result = process.Terminate() |
显示Win32_Process类的.Create方法的接口
注：wmi模块会接受WMI方法的传入参数作为Python的关键字参数，并把传出参数作为一个元组进行返回。
1 2 3 4 | import wmi c = wmi.WMI()
print c.Win32_Process.Create |
显示没有处于正常运行状态的自启动服务
1 2 3 4 5 6 7 8 9 | import wmi c = wmi.WMI()
stopped_services = c.Win32_Service(StartMode="Auto", State="Stopped") if stopped_services: for s in stopped_services: print s.Caption, "service is not running" else: print "No auto services stopped" |
显示每个固定磁盘的剩余空间百分比
1 2 3 4 5 | import wmi c = wmi.WMI()
for disk in c.Win32_LogicalDisk(DriveType=3): print disk.Caption, "%0.2f%% free" %(100.0 * long(disk.FreeSpace) / long(disk.Size)) |
运行记事本，等它关闭之后显示它里面的文字
注：这个例子是运行一个进程并且知道它什么时候结束，而不是去处理输入到记事本里面的文字。所以我们只是简单的用记事本打开一个指定文件，等到用户完成输入并关闭记事本之后，显示一下它的内容。
本例不适用于远程机器，因为处于安全考虑，在远程机器上启动的进程是没有界面的（你在桌面上是看不到它们的）。这类远程操作的技术多用于在服务器上运行一个安装程序，安装结束之后重启机器。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | import wmi c = wmi.WMI()
filename = r"c:\temp\temp.txt" process = c.Win32_Process process_id, result = process.Create(CommandLine="notepad.exe " + filename) watcher = c.watch_for( notification_type="Deletion", wmi_class="Win32_Process", delay_secs=1, ProcessId=process_id )
watcher() print "This is what you wrote:" print open(filename).read() |
监视新的打印任务
1 2 3 4 5 6 7 8 9 10 11 12 | import wmi c = wmi.WMI()
print_job_watcher = c.Win32_PrintJob.watch_for( notification_type="Creation", delay_secs=1 )
while 1: pj = print_job_watcher() print "User %s has submitted %d pages to printer %s" % \ (pj.Owner, pj.TotalPages, pj.Name) |
重启远程机器
注：要对远程系统进行这样的操作，WMI脚本必须具有远程关机(RemoteShutdown)的权限，也就是说你必须在连接别名中进行指定。WMI构造器允许你传入一个完整的别名，或者是指定你需要的那一部分。使用wmi.WMI.__init__的帮助文档可以找到更多相关内容。
1 2 3 4 5 6 | import wmi # other_machine = "machine name of your choice" c = wmi.WMI(computer=other_machine, privileges=["RemoteShutdown"])
os = c.Win32_OperatingSystem(Primary=1)[0] os.Reboot() |
对于启用IP的网卡显示其IP和MAC地址
1 2 3 4 5 6 7 8 | import wmi c = wmi.WMI()
for interface in c.Win32_NetworkAdapterConfiguration(IPEnabled=1): print interface.Description, interface.MACAddress for ip_address in interface.IPAddress: print ip_address |
查看自启动项
1 2 3 4 5 | import wmi c = wmi.WMI()
for s in c.Win32_StartupCommand(): print "[%s] %s <%s>" %(s.Location, s.Caption, s.Command) |
监视事件日志中的错误信息
1 2 3 4 5 6 7 8 9 10 11 12 | import wmi c = wmi.WMI(privileges=["Security"])
watcher = c.watch_for( notification_type="Creation", wmi_class="Win32_NTLogEvent", Type="error" ) while 1: error = watcher() print "Error in %s log: %s" %(error.Logfile, error.Message) # send mail to sysadmin etc. |
列出注册表子键
注：本例及以下几例使用了Registry()这个方便的函数，此函数是早期加入到wmi包的，它等效于：
1 2 | import wmi r = wmi.WMI(namespace="DEFAULT").StdRegProv |
1 2 3 4 5 6 7 8 9 10 | import _winreg import wmi
r = wmi.Registry() result, names = r.EnumKey( hDefKey=_winreg.HKEY_LOCAL_MACHINE, sSubKeyName="Software" ) for key in names: print key |
增加一个新的注册表子键
1 2 3 4 5 6 7 8 | import _winreg import wmi
r = wmi.Registry() result, = r.CreateKey( hDefKey=_winreg.HKEY_LOCAL_MACHINE, sSubKeyName=r"Software\TJG" ) |
增加一个新的注册表键值
