保持批处理脚本CMD窗口上新开的CMD窗口的顶部 [英] Keep batch script CMD window on top of newly opened CMD windows

问题描述

也许一个简单的答案，但不能在网上找到它。

Probably an easy answer but can't find it online.

我有一个蝙蝠脚本打开某些程序，也希望用户输入（Y [N]），这一切工作正常。

I have a .bat script to open some programs and also wants user input (Y[N]) which it all works fine.

我的问题。

如何保持在新开的窗口之上脚本窗口，使用户可以看到该脚本寻找一些输入

How can I keep the script window on top of the newly opened windows so the user can see the the script is looking for some input.

@ECHO OFF
REM  2016-06-17 GMAN

REM Start Zookeeper
cd zookeeper-3.4.8 
CALL StartZookeeper.bat

REM Give Zookeeper a chance to start
sleep 4

REM Start Kafka
cd ..\kafka_2.11-0.10.0.0 
CALL StartKafka.bat

REM Give Kafka a chance to start
sleep 2

setlocal
:PROMPT
SET /p prodCons="Open a CMD for Producer and Consumer: (Y/[N]"?)
echo You entered: %prodCons%
sleep 1

IF /I "%prodCons%" NEQ "Y" GOTO END

REM Producer Terminal
start cmd.exe /k "TITLE Producer && cd .\kafka_2.11-0.10.0.0\bin\windows"

REM Consumer Terminal
start cmd.exe /k "TITLE Consumer && cd .\kafka_2.11-0.10.0.0\bin\windows"   

:END
endlocal

我的脚本窗口背后却隐藏着新的CMD使用户可以看到输入Y或N

My script window is hidden behind the new CMD so user can see to enter Y or N.

推荐答案

要设置总在最前面标志的一种方法是导入的 SetWindowPos从user32.dll中（）函数并调用它与论据：

One way to set the Always On Top flag is to import the SetWindowPos() function from user32.dll and invoke it with arguments which:

• 的父窗口设置为HWND_TOPMOST（-1）


• 跳过调整/ SWP_NOMOVE带（0x01）的和SWP_NOSIZE（0X02）标志移动窗口

有没有办法在纯批次做到这一点，但你可以有PowerShell的做繁重。这里有一个蝙蝠+的PowerShell脚本混合模板可以在其中粘贴您的批处理code键使控制台总在最前面：

There's no way to do this in pure batch, but you can have PowerShell do the heavy lifting. Here's a bat + PowerShell hybrid script template into which you can paste your batch code to make the console always on top:

<# : AlwaysOnTop.bat -- http://stackoverflow.com/a/37912693/1683264
@echo off & setlocal

rem // Relaunch self in PowerShell to run this window Always On Top
powershell -noprofile "iex (${%~f0} | out-string)"

rem /* ###############################
rem    Your main batch code goes here.
rem    ############################### */

goto :EOF
rem // end batch / begin PowerShell hybrid code #>

# // Solution based on http://stackoverflow.com/a/34703664/1683264
add-type user32_dll @'
    [DllImport("user32.dll")]
    public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter,
        int x, int y, int cx, int cy, uint uFlags);
'@ -namespace System

# // Walk up the process tree until we find a window handle
$id = $PID
do {
    $id = (gwmi win32_process -filter "ProcessID='$id'").ParentProcessID
    $hwnd = (ps -id $id).MainWindowHandle
} while (-not $hwnd)

$rootWin = [IntPtr](-1)
$topmostFlags = 0x0003
[void][user32_dll]::SetWindowPos($hwnd, $rootWin, 0, 0, 0, 0, $topmostFlags)

你也可以使用 GetWindowLong（） 查询扩展窗口样式，以确定是否窗口已经始终设置在顶部 - 然后切换它

---

One can also use GetWindowLong() to query extended window styles to determine whether the window is already set always on top -- then toggle it.

<# : AlwaysOnTop2.bat -- http://stackoverflow.com/a/37912693/1683264
@echo off & setlocal

call :toggleAlwaysOnTop

rem /* ###############################
rem    Your main batch code goes here.
rem    ############################### */

goto :EOF

:toggleAlwaysOnTop
powershell -noprofile "iex (${%~f0} | out-string)"
goto :EOF
rem // end batch / begin PowerShell hybrid code #>

add-type user32_dll @'
    [DllImport("user32.dll")]
    public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter,
        int x, int y, int cx, int cy, uint uFlags);

    [DllImport("user32.dll")]
    public static extern int GetWindowLong(IntPtr hWnd, int nIndex);
'@ -namespace System

$id = $PID
do {
    $id = (gwmi win32_process -filter "ProcessID='$id'").ParentProcessID
    $hwnd = (ps -id $id).MainWindowHandle
} while (-not $hwnd)

$style = [user32_dll]::GetWindowLong($hwnd, -20)
# // If flag 0x08 is set, make parent HWND -2 to unset it.  Otherwise, HWND -1 to set it.
[IntPtr]$rootWin = ($style -band 0x08) / -8 - 1
[void][user32_dll]::SetWindowPos($hwnd, $rootWin, 0, 0, 0, 0, 0x03)
