使cmd窗口位于其他窗口之上

Question

我正在编写一个简单的批处理脚本来隐藏用户输入的密码。解决方案是创建一个弹出窗口并更改该弹出窗口的文本颜色。以下是代码，它正常工作

@echo off
Echo Please enter your password in the popup window and then press enter
set tempbat="%temp%p.cmd"
REM Create temporary batch file to make popup window for entering password 'masked'
echo mode 20,1 >%tempbat%
echo color 01 >>%tempbat%
echo Title Enter Password >>%tempbat%
echo setlocal enabledelayedexpansion >>%tempbat%
echo set /p Pass= >>%tempbat%
echo echo !pass!^>"%temp%pass.txt" >>%tempbat%
echo exit >>%tempbat%
start /wait "" %tempbat%
del %tempbat% 2>NUL
set /p Pwd=<"%temp%pass.txt"
del "%temp%pass.txt" 2>NUL
echo %Pwd%

我唯一担心的是，当弹出窗口发生时，我是否可以将其设置为始终位于主cmd窗口的顶部，甚至禁用对主cmd的访问（我预计会出现类似Bootstrap Modal的行为）？

感谢阅读并希望收到您的帮助

可以批量模糊用户输入，而不是试图用某些东西来覆盖密码。从以下答案中查看MC ND的代码：

@echo off
setlocal enableextensions disabledelayedexpansion
rem Call the subroutine to get the password    
call :getPassword password 
rem Echo what the function returns
if defined password (
    echo You have typed [%password%]
) else (
    echo You have typed nothing
)
rem End of the process    
endlocal
exit /b

rem Subroutine to get the password
:getPassword returnVar
setlocal enableextensions disabledelayedexpansion
set "_password="
rem We need a backspace to handle character removal
for /f %%a in ('"prompt;$H&for %%b in (0) do rem"') do set "BS=%%a"
rem Prompt the user 
set /p "=password ?:" <nul 
:keyLoop
rem retrieve a keypress
set "key="
for /f "delims=" %%a in ('xcopy /l /w "%~f0" "%~f0" 2^>nul') do if not defined key set "key=%%a"
set "key=%key:~-1%"
rem handle the keypress 
rem     if No keypress (enter), then exit
rem     if backspace, remove character from password and console
rem     else add character to password and go ask for next one
if defined key (
    if "%key%"=="%BS%" (
        if defined _password (
            set "_password=%_password:~0,-1%"
            setlocal enabledelayedexpansion & set /p "=!BS! !BS!"<nul & endlocal
        )
    ) else (
        set "_password=%_password%%key%"
        set /p "=*"<nul
    )
    goto :keyLoop
)
echo(
rem return password to caller
if defined _password ( set "exitCode=0" ) else ( set "exitCode=1" )
endlocal & set "%~1=%_password%" & exit /b %exitCode%
