Put editable text in command prompt with bat file - windows

Question

I have a bat script that asks for user input with the next line
SET /P returnString=Enter string: %=%
Now I want default input visible on the command line, like:
Enter string: defaultstring
To clarify: I don't want a default value if no input is given, I want the default value visible and editable on the command line, so in the case described above the defaultstring could be replaced for a different text.
Is this possible with SET in a batch file? If not, how could I accomplish this?

Answer 1

Here is a Batch + JScript hybrid script that prompts with a default value.
#if (#CodeSection == #Batch) #then
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
:: The first line in the script is...
:: in Batch, a valid IF command that does nothing.
:: in JScript, a conditional compilation IF statement that is false.
:: So the following section is omitted until the next "[at]end".
:: Note: the "[at]then" is required for Batch to prevent a syntax error.
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
:: Batch Section
#echo off
setlocal
set "Input="
set "Default=Hello World"
title MyUniqueTitle
CScript //E:JScript //Nologo "%~f0" "MyUniqueTitle" "%Default%"
set /p "Input=> Prompt: "
if defined Input set "Input=%Input:"=%"
echo(%Input%
endlocal
exit /b 0
:: End of Batch
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
#end
////////////////////////////////////////////////////////////////////////////////
// JScript Section
try
{
var WshShell = WScript.CreateObject('WScript.Shell');
var Title = WScript.Arguments.Item(0);
var Message = WScript.Arguments.Item(1);
WshShell.AppActivate(Title);
WshShell.SendKeys(Message);
WScript.Quit(0);
}
catch(e)
{
WScript.Echo(e);
WScript.Quit(1);
}
WScript.Quit(2);

Well, it's not exactly what you asked for but I think it's better. This will create a browseforfolder dialog and let your user pick what folder to use. In this example r is the return variable from the function. It will return an errorlevel of 0 if a folder is chosen and 1 if the cancel button is hit.
#Echo off
setlocal
Call :BrowseFolder "Enter path to folder" "C:\scripts\" r
echo %r%
echo %errorlevel%
pause
Goto :EOF
:BrowseFolder <Title> <DefaultStartPath> <Return>
setlocal
set vbs="%temp%\_.vbs"
if exist %vbs% del /f /q %vbs%
>%vbs% echo set sh=wscript.CreateObject("Shell.Application")
>>%vbs% echo set f=sh.BrowseForFolder(0,%1,0,%2)
>>%vbs% echo if typename(f)="Nothing" Then
>>%vbs% echo wscript.echo "Dialog Cancelled"
>>%vbs% echo wscript.Quit(1)
>>%vbs% echo end if
>>%vbs% echo set fs=f.Items():set fi=fs.Item()
>>%vbs% echo p=fi.Path:wscript.echo p
for /f "tokens=*" %%a in ('cscript //nologo %vbs%') do set result=%%a
if exist %vbs% del /f /q %vbs%
if "%result%" EQU "Dialog Cancelled" (set a=1) else set a=0
endlocal & set %3=%result% & exit /b %a%
