中国DOS联盟论坛 » DOS批处理 & 脚本技术（批处理室） » Here is a batch script example to achieve displaying `*` when inputting characters: ```batch @echo off setlocal enabledelayedexpansion set "password=" echo Please enter your password: :input set "key=" for /f "delims=" %%a in ('choice /c 0123456789abcdefghijklmnopqrstuvwxyz /t 0 /d 0 /n set /p "key=" if "!key!"=="" goto input set "password=!password!!key!" echo * goto input ``` Please note that this is a simple example, and there are more advanced ways to handle password input and security, but this basic script can display `*` while inputting characters.

Referenced the original大人 Herbert Kleebauer's ASCODE part

@echo off&cls

chcp 437>nul&graftabl 936>nul

for /f "delims=: tokens=1" %%i in ('findstr /i /n "^:writepass$" "%~f0"') do set line=%%i

<"%~f0" more +%line%|debug>nul

set "ps="

set n=0

set /p=请输入密码:<nul

:start

if %n%==256 (

echo &&goto e

) else (

for /f "delims=" %%i in ('password.com') do (

if "%%i"=="?" goto e

set "q=%%i"

if "%%i" equ "?" (call :p "%%i") else (

if "%%i" lss "? " (GOTO :start)

set /p=*<nul

set /a n+=1

if "%%i" geq "? " call set "ps=%%ps%%%%q:~1%%"

)))

goto start

:p

if not "%ps%" equ "" (

set "ps=%ps:~0,-1%"

SET /p= <nul

)

GOTO :eof

:e

:::Here you can do what you wanna do:::

echo.

echo 密码为:"%ps%"

When saving the building owner's code as a CMD and running it, it prompts: "password.com is not a valid Win32 application. Access denied"

Hehe. I'm sorry, upstairs. I forgot to change that signature. [Hey, being a moderator is way out of my reach!]
Also, try saving it as *.bat in floor 4.
