3.1 or 3.5?

Either, or NT4, or Win2K resource kit
k thnx, i got 3.5
gonna learn to use it now Quote from: PirateSamir on January 26, 2009, 11:38:43 AM

gonna learn to use it now

Code: [Select]Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\>choice /?
CHOICE [/C[:]choices] [/N] [/S] [/T[:]c,nn] [text]

/C[:]choices SPECIFIES allowable keys. Default is YN
/N Do not display choices and ? at end of prompt string.
/S Treat choice keys as case sensitive.
/T[:]c,nn Default choice to c after nn seconds
text Prompt string to display

ERRORLEVEL is set to OFFSET of key user presses in choices.
ok, 2 questions
how would define your default choice?
and
what is errorlevel? (i've seen it quite oftenly in batch files) Quote from: PirateSamir on January 26, 2009, 11:55:00 AM

ok, 2 questions

and
what is errorlevel? (i've seen it quite oftenly in batch files)

Example

Default choice is Y, timeout is 10 seconds

Code: [Select]choice /C:YN /T:Y,10 Press Y or N
echo errorlevel is: %errorlevel%

If Y was PRESSED (or timeout occurred) the %errorlevel% will be 1 (because Y is choice 1) and if N was pressed %errorlevel% will be 2 (because N is the second choice)

errorlevel is a system variable which is set by a program. Often 0=no ERROR, 1 or more means an error. Choice uses it to PASS the key pressed.

Code: [Select]S:\>chtest1.bat
Press Y or N [Y,N]?Y
errorlevel is: 1

S:\>chtest1.bat
Press Y or N [Y,N]?N
errorlevel is: 2so can errorlevel be used for anything else?Quote from: PirateSamir on January 26, 2009, 12:49:58 PM

so can errorlevel be used for anything else?

Yes.

Code: [Select]dir *.txt
if %errorlevel% GTR 0 echo "No text files"

Plenty of information if you use Google.

ok thnx Quote from: hiteshsavla on January 23, 2009, 03:16:25 PM

Code: [Select]@ECHO OFF

:choice
set /P c=Are you sure you want to continue[Y/N]?
if /I "%c%" EQU "Y" goto :somewhere
if /I "%c%" EQU "N" goto :somewhere_else
goto :choice

:somewhere

echo "I am here because you typed Y"
pause
exit

:somewhere_else

echo "I am here because you typed N"
pause
exit
