Invoking an exe from Javascript with Arguments

Question

I'm trying to invoke cmd.exe from JavaScript with arguments. But it is opening cmd.exe and doing nothing.

Below is the script.

function f_InvokeEXE() {
        var oShell = new ActiveXObject("WScript.shell");
        var commandtoRun = '"C:\\Windows\\system32\\cmd.exe"';
        var argumentString = '"C:\\Program Files (x86)\\PICT\\pict.exe" "C:\\Program Files (x86)\\PICT\\Sample.txt" > "C:\\Program Files (x86)\\PICT\\pab.xls"';
        var a = oShell.run(commandtoRun + ' ' + argumentString, 1, true);
    }

Its working fine when manually doing that. (opening command prompt and entering that command).

Answer 1

Use the /c arg for cmd.exe. Without that, it will NOT execute your command string:

C:\Users\marc>cmd echo foo
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\Users\marc>exit

C:\Users\marc>cmd /c echo foo
foo

C:\Users\marc>

Note how the version WITHOUT /c just starts up a NEW shell.
