WScript SendKeys escape special characters


I want to make a bat file that prompt user with a default value. All`s fine, I found a CScript way.

But i have a problem with special characters like pharanteses..

bat file is

set "mysql_password="
title MyUniqueTitle
CScript //E:JScript //Nologo "%cscripts_path%\sendkeys.js" "MyUniqueTitle" "&GS)u**,o7,r"
set /p "mysql_password=> Enter new MySQL Password: "

and sendkeys.js

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);

Problem is with WshShell.SendKeys(Message) , here i should use an escape function that put bracets to special characters..

Does anyone know an way to escape Message code from SendKeys?

Thanks!


Solution

  • Just escape the special characters with string substitution in the batch file first.

    @if (@CodeSection == @Batch) @then
    
    @echo off &setlocal enabledelayedexpansion
    
    set "password=&GS)+[]+u**,o7,r"
    
    SET "password=!password:)={)}!"
    SET "password=!password:+={+}!"
    SET "password=!password:[={[}!"
    SET "password=!password:]={]}!"
    
    rem Enter the prefill value
    CScript //nologo //E:JScript "%~F0" "!password!"
    rem Read the variable
    echo -----------------------------------------------------------
    set /P "password=Please enter your password: "
    echo password=!password!
    pause
    goto :EOF
    
    @end
    
    WScript.CreateObject("WScript.Shell").SendKeys(WScript.Arguments(0));
