I would like to create an update function that works just after the user is prompted to type into the "ChatBox" so that other users on my school network can type and all other users can see it without having to restart the program or typing space to reload the .txt file
here is the code I have written so far;
:enter
cls
type cblog.txt
echo.
set /p text=
echo %text% >> cblog.txt
goto enter
I like this topic, so I wrote a fully working prototype:
#echo off
setlocal
if "%~1" equ "" echo You must give your username as parameter & goto :EOF
set "user=%~1"
set "now=%time%"
echo %now%: User %user% entered the chat room>> msgQueue.txt
call :chatRoom 3< msgQueue.txt
goto :EOF
:chatRoom
rem Omit previous messages
:omitMsg
set /P "msg=" <&3
if "%msg:~0,12%" neq "%now%:" goto omitMsg
echo %msg%
echo/
echo Press S to send a message or eXit to end
echo/
:msgLoop
rem Check for new messages received
:showMsg
set "msg="
set /P "msg=" <&3
if not defined msg goto send
echo %msg%
goto :showMsg
rem Check to send a new message
:send
ver > NUL
choice /C SNX /N /T 3 /D N > NUL
if errorlevel 3 goto end
if errorlevel 2 goto msgLoop
rem Send a message
echo -----------------------------------
set /P "msg=Message: "
echo -----------------------------------
echo %user%: %msg% >> msgQueue.txt
goto msgLoop
:end
echo %time%: User %user% leaved the chat room>> msgQueue.txt
The response time may be adjusted in /T 3 parameter of choice command: shorter times makes the chat more responsive, but it consume more CPU time.
Below is an image that show a test with four users in the Chat Room:

So the problem is that it crashes after the :LOGIN part and I don't know what to do!
I'm trying to make an OS batch (something like MS-DOS), but it crashes after the "login" part.
I tried everything I could think of and it didn't work, also I want to make a save file so users can set a password for their "account".
As mentioned in above comments, you need to correctly use your variables, you can however use choice instead of set /p for your commands.
#echo off

echo welcome to windows 71
echo Before we begin please type your name
set /P "_name=here:"
if /i "_%name%"=="admin" goto admin
rem ms=menu start
:ms
echo %time%
echo hello %_name%
echo type HELP for list to commands
CHOICE /C HEC /M "Press H for Help, E to exit C for Calender."
goto opt%errorlevel%
:admin
echo hello %_name% to the admin panel
echo type HELP for list to commands
CHOICE /C HEC /M "Press H for Help, E to exit C for Calender."
goto opt%errorlevel%
:opt1
echo Help stuff goes here
goto :eof
:opt2
exit
:opt3
echo Calenders stuff goes here
Some things to note. You do not require to goto ms is the user is not admin as the statement for not being admin will not be met, we will automatically faal through into the ms label.
Notice where the problems were in your code. i.e if %name%=admin should be if "%_name%"=="admin" with double equal sign and the underscore in the name. It is also double quoted to ensure that we do a match without unwanted whitespace. Lastly /I option to catch ADMIN in any case.
See if /?, choice /? from command line for more help around these functions.
Okay this code is quite wrong.
I fixed it.
#echo off

set /p name=here:

if not "%name%"=="admin" goto ms
rem ms=menu start

echo %time%
echo Hello %name%
echo Type HELP for list to commands

echo type HELP for list to commands
set /P command=here:
if "%command%"=="help" goto help
if "%command%"=="exit" goto exit
if "%command%"=="calendar" goto cal
GOTO :ADMIN
Okay but you don't need to start systeminfo and all that.
(This is my first post here, so bear with me)
Can you show the last user-input in a batch file? I'm gonna try to keep it simple here.
#echo off
:menu
echo Type 1 to proceed.
set /p example=
if "%example%" == "1" GOTO :proceed
GOTO :error
:proceed
pause
:error
cls
echo You wrote (last user input), that's not correct.
timeout 30
GOTO :menu
I know that I could replace the (last user input) with %example%, but then I'd have to make custom error messages for every category, and there are about 50 of them. It'd be easier with a last input command.
By the way, I've taught myself everything that I know about batch, so my example probably has major issues right now, but it works somehow.
You could centralize all user input into a function (user_input)
:menu1
echo Type 1 to proceed.
call :userInput example
if "%example%" == "1" GOTO :proceed
GOTO :error
:menu2
echo Type 42 to proceed.
call :userInput answer
if "%answer%" == "42" GOTO :proceed
GOTO :error
:userInput
set /p LAST_INPUT=
set "%1=%LAST_INPUT%"
exit /b
:proceed
pause
:error
cls
echo You wrote "%LAST_INPUT%", that's not correct.
timeout 30
GOTO :menu
I don't know how to do it without temp file. TO get the things written int the console you need the doskey /history (this will skip the running of the script itself):
#echo off
setlocal enableDelayedExpansion
set "last="
set "but_last="
doskey /history > log.txt
for /f "tokens=* delims=" %%# in (log.txt) do (
set "but_last=!last!"
set "last=%%#"
)
echo "%but_last%"
del /s /q log.txt >nul 2>nul
Everything in this batch script works fine, but when I enter the IF statement, for some reason set /p id= doesn't actually capture anything. In fact shortly after it will echo:
You chose session %id%.
but that will return a blank, as though nothing was entered for ID.
Any advice would be greatly appreciated.
#echo off
echo Please be sure CMD is being run as an administrator.
echo.
:loop
set /p targetpc="Which PC would you like to query for users (Hostname or IP)?: "
echo.
echo Querying %targetpc%...
echo.
quser /server:%targetpc%
echo.
set /p choice="Would you like to log a user off of %targetpc%? [Y/N]: "
echo.
IF /I "%choice%" EQU "Y" (
echo Enter user's session ID:
set /p id=
echo.
echo You chose session %id%.
echo.
logoff %id% /server:%targetpc% /V
echo.
echo Done!
echo.
goto loop
)
IF /I "%choice%" EQU "N" (
goto loop
)
You are using the %id% value within the same block where it is set. This being the case, you need to use delayed expansion.
Add these lines to the top and bottom of your script, respectively:
SETLOCAL EnableDelayedExpansion
<Your script>
ENDLOCAL
Now use delayed expansion notation with your block (! around variables instead of %):
IF /I "%choice%" EQU "Y" (
echo Enter user's session ID:
set /p id=
echo.
echo You chose session !id!.
echo.
logoff !id! /server:%targetpc% /V
echo.
REM Note, replacing with a period here.
echo Done.
echo.
goto loop
)
There are tons of other questions on this site regarding delayed expansion, so a quick search within the batch-file tag should yield lots of additional info if you need it.
I am writing a batch file that when it is run captures the windows login, date, and time. I would like to place a counter in the batch that tracks if the batch file was opened and increments by 1 if the answer to the second question (in bold) is "y". If the counter is = 1 then a message displays with a message along with the username, date, and time (in italics). If the answer to either of the questions is "n" then the "goodbye" is displayed and the batch closes. I am getting syntax errors and need some help. Thank you :).
new batch file
#ECHO OFF

Has the check been done [y/n]
I am not quite understanding your description of your program but I am die hard fan of a specific formatting and syntax of batch files. I receive no syntax errors when I execute your code like this.
#ECHO OFF
:: count loop
set var1=0
:loop
set /a var1=%var1%+1
echo %var1%
if %var1% EQU 1 (
goto end
) else (
goto loop
)
:end
echo "the DOSE report has already been sent by %USERNAME% on %DATE% at %TIME%"
:: ask user
:choice
set /P c=Has the check been done [y/n]
if /i %c%==y (
set /P c=Do you want to send the DOSE report[y/n]?
) else (
if /i %c%==n goto goodbye
)
if /i %c%==y (
ECHO "L:\NGS\HLA LAB\total quality management\QC & QA\DOSE reports\DOSE reporting form.xlsm"
) else (
if /i %c%==n goto goodbye
)
:goodbye
echo "goodbye"
pause
so in this code
:chat
cls
findstr /v "sdlkfjsdlkfs98dfu9sd8f6ysd954" \\Cap\FileServer\Recive\chatroom.chatfile
echo.
echo ----------------------------------------------------------
echo.
color 0b
goto chat1
:chat1
ping localhost -n 3 >nul
set /p text=Text:
echo %name% : %text% >>\\Cap\FileServer\Recive\chatroom.chatfile
goto chat
So i was wondering if i can make it not wait for the Text: and go on to refreshing the chat file if there is no input.
You cannot do this with Batch as once you have prompted the user, the execution will wait until input is received.
Perhaps as a workaround, you can "refresh" when empty input is received:
:chat
cls
findstr /v "sdlkfjsdlkfs98dfu9sd8f6ysd954" \\Cap\FileServer\Recive\chatroom.chatfile
echo.
echo ----------------------------------------------------------
echo.
color 0b
goto chat1
:chat1
REM Reset any existing text value.
set "text="
ping localhost -n 3 >nul
set /p text=Text:
REM Check for input.
IF NOT "%text%"=="" (
REM Input was given. Write it to the file.
echo %name% : %text% >>\\Cap\FileServer\Recive\chatroom.chatfile
)
goto chat
So in the above, if the user just presses Enter at the prompt, nothing will be written to the chatfile and the loop will start over.
