首先，您应该检查一下 WASP，看看它是否适合您的需求:http://wasp.codeplex.com/

其次，我修改了此处找到的代码 http://social.technet.microsoft.com/Forums/windowsserver/en-US/c3cd3982-ffc5-4c17-98fc-a09c555e121c/get-all-child-window-titles?forum=winserverpowershell

Secondly, I have modified code found here http://social.technet.microsoft.com/Forums/windowsserver/en-US/c3cd3982-ffc5-4c17-98fc-a09c555e121c/get-all-child-window-titles?forum=winserverpowershell

创建一个函数，它将 MainWindowHandle 作为输入，并返回一个带有子句柄 ID 的对象(它还将列出任何窗口标题，如果有).

to create a function that will take a MainWindowHandle as input, and will give you an object with child handle IDs back (It will also list any window titles, if any).

我希望其中一种方法可以满足您的需求:)

I hope one of these methods will give you what you need :)

            $rtnlen = [apifuncs]::GetWindowText($hwnd,$sb,$sb.Capacity)

您可以直接从 Get-Process 的结果中通过管道传输它，如下所示:

You can pipe it directly from the result of Get-Process, like this:

Get-Process | Where-Object {$_.ProcessName -eq 'OUTLOOK'} | Get-ChildWindow
