我有这个脚本
Get-Process | Where-Object {$_.MainWindowTitle -like "*total*"}
哪个产生此信息
Handles NPM(K) PM(K) WS(K) VM(M) CPU(s) Id ProcessName
------- ------ ----- ----- ----- ------ -- -----------
362 23 19432 32744 324 3.86 6880 TotalCmd64
所以我有进程ID。
*Total*
应用程序有许多自己的打开窗口。
问题
如何通过所有窗口迭代(使用powershell)(这样我可以得到它们的窗口句柄)?
注意:我的目标是什么?
:
在Visual Studio中查看(例如):我正在运行应用程序 但应用程序有自己的打开窗口。
我希望子窗口是TOPMOsT。我已经脚本使窗口最顶层。但是我需要它的句号。
答案 0 :(得分:19)
首先,您应该查看WASP,看看它是否符合您的需求:http://wasp.codeplex.com/
中的代码创建一个将MainWindowHandle作为输入的函数,并为您提供一个带有子句柄ID的对象(它还会列出任何窗口标题,如果有的话)。
我希望其中一种方法可以满足你的需要:)
function Get-ChildWindow{
[CmdletBinding()]
param (
[Parameter(ValueFromPipeline = $true, ValueFromPipelinebyPropertyName = $true)]
[ValidateNotNullorEmpty()]
[System.IntPtr]$MainWindowHandle
)
BEGIN{
function Get-WindowName($hwnd) {
$len = [apifuncs]::GetWindowTextLength($hwnd)
if($len -gt 0){
$sb = New-Object text.stringbuilder -ArgumentList ($len + 1)
$rtnlen = [apifuncs]::GetWindowText($hwnd,$sb,$sb.Capacity)
$sb.tostring()
}
}
if (("APIFuncs" -as [type]) -eq $null){
Add-Type @"
using System;
using System.Runtime.InteropServices;
using System.Collections.Generic;
using System.Text;
public class APIFuncs
{
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern int GetWindowText(IntPtr hwnd,StringBuilder lpString, int cch);
[DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)]
public static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)]
public static extern Int32 GetWindowThreadProcessId(IntPtr hWnd,out Int32 lpdwProcessId);
[DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)]
public static extern Int32 GetWindowTextLength(IntPtr hWnd);
[DllImport("user32")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool EnumChildWindows(IntPtr window, EnumWindowProc callback, IntPtr i);
public static List<IntPtr> GetChildWindows(IntPtr parent)
{
List<IntPtr> result = new List<IntPtr>();
GCHandle listHandle = GCHandle.Alloc(result);
try
{
EnumWindowProc childProc = new EnumWindowProc(EnumWindow);
EnumChildWindows(parent, childProc,GCHandle.ToIntPtr(listHandle));
}
finally
{
if (listHandle.IsAllocated)
listHandle.Free();
}
return result;
}
private static bool EnumWindow(IntPtr handle, IntPtr pointer)
{
GCHandle gch = GCHandle.FromIntPtr(pointer);
List<IntPtr> list = gch.Target as List<IntPtr>;
if (list == null)
{
throw new InvalidCastException("GCHandle Target could not be cast as List<IntPtr>");
}
list.Add(handle);
// You can modify this to check to see if you want to cancel the operation, then return a null here
return true;
}
public delegate bool EnumWindowProc(IntPtr hWnd, IntPtr parameter);
}
"@
}
}
PROCESS{
foreach ($child in ([apifuncs]::GetChildWindows($MainWindowHandle))){
Write-Output (,([PSCustomObject] @{
MainWindowHandle = $MainWindowHandle
ChildId = $child
ChildTitle = (Get-WindowName($child))
}))
}
}
}
您可以直接从Get-Process的结果中对其进行管道处理,如下所示:
Get-Process | Where-Object {$_.ProcessName -eq 'OUTLOOK'} | Get-ChildWindow
