Question

I would like a batch file that can register a user into itself.
something like:

@echo off
echo Choose an option:
echo     1:Register
echo     2:Login
Set option=
set /p option=Your option: 
if %option%==1 goto reg
if %option%==2 goto login
...
:reg
--The registration script--
goto login
...
:login
Set usr=
set /p usr=Username: 
if %usr%== goto pass
echo False username!
@pause
goto login
...
:pass
Set passw=
set /p passw=Password: 
if %passw%== goto success
echo False password!
@pause
goto login

So… something like that. ‘if %passw%== “” and if %usr%== “”‘ === it should automatticly make that at registration.

It will be nice if more than 1 people could register.

Answer 1

Hmmm. This is what i found out by some help:

@echo off
title REGISTERANDLOGIN
if exist programbase.dll goto login
if not exist programbase.dll goto register

:register
title Register
echo Register
echo.
echo Please fill in the blanks.
echo.
Set usrname=
set /p usrname=Username: 
Set passw=
set /p passw=Password: 
echo %usrname%>> programdata.dll
echo %passw%>> programbase.dll
goto login

:login
:begin
set usr=
set /p usr=Enter your username: 
if {%usr%}=={} goto :begin
set authenticated=
for /f "tokens=*" %%a in (programdata.dll) do (
    if {%%a}=={%usr%} set authenticated=true
)

if not defined authenticated (echo Invalid Username & goto :begin)

:passwo
set pass=
set /p pass=Enter your password: 
if {%pass%}=={} goto :begin
set authenticated=
for /f "tokens=*" %%a in (programbase.dll) do (
    if {%%a}=={%pass%} set authenticated=true
)
if not defined authenticated (echo Invalid password & goto :begin)

:loggedin
cls
echo Welcome.
@pause
exit /b 0
