Pass string with quote into a VB application with cscript.exe

Question

I have a VB script that takes in several parameters that could include spaces using cscript, and I make the call using:

nsExec::exec 'cscript.exe "$PATH_TO_FILE\program.vbs" "Something with spaces" "Something else"'

Now, I want one of the "Something else" strings to include a double quote character, where the string is

Something " else.

I have tried

nsExec::exec 'cscript.exe "$PATH_TO_FILE\program.vbs" "Something with spaces" "Something "" else."'

with an escaped " but that did not work, it simply used "Something else" as the string passed in.

You can read the entire process command line as one string like this (JScript code, sorry):

// Read process command line
var WshShell = WScript.CreateObject("WScript.Shell");
var objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\\\.\\root\\cimv2");
var childProcess =
    WshShell.Exec
    (
        '"' + WshShell.Environment('PROCESS')('ComSpec') + '"'
        +
        " /C Echo \"Text lines\" && Set /p VarName="
    );
childProcess.StdOut.ReadLine();
var current_pid =
    objWMIService.ExecQuery
        (
        "Select * From Win32_Process Where ProcessId=" + childProcess.ProcessID
        );
current_pid = (new Enumerator(current_pid)).item().ParentProcessId;
if (current_pid)
{
    childProcess.StdIn.WriteLine("value");  // child process should now exit
}
else
{
    WScript.StdErr.WriteLine("Get current PID from WMI failed.");
    WScript.Quit(7);
}

var cmd_line = objWMIService.ExecQuery("Select * From Win32_Process Where ProcessID=" + current_pid);

cmd_line = (new Enumerator(cmd_line)).item().CommandLine;
WScript.Echo(cmd_line);

but than you will have to parse the string into separate arguments yourself.

Basically, there is not a way to deal with these quotes, so you need a workaround (use QUOTE and then replace in program with a ').
