hta/ javascript How to execute an application with relative path

I'm building a .hta (with javascript) from which i want to launch several applications.

But when i execute my .hta i get the error message can't find file

this is the code:

<script type="text/javascript" language="javascript">
    function RunFile(path) {
    var relpath = window.location.href;
    var fullpath = relpath + path;

    WshShell = new ActiveXObject("WScript.Shell");
    WshShell.Run(fullpath, 1, false);
    }

    RunFile("\file.exe");
</script>

Solution

window.location.href includes filename and protocol too. Try this:

var relpath = window.location.pathname.replace(/\\/g,'/').split('/');
relpath.pop();// JScript: relpath.length = relpath.length - 1;
relpath = relpath.join('/') + '/';

Notice use of / instead \, and it's also handy to end up relpath with /, so you don't need to add it to function argument.

EDIT

I'm not sure what you mean with getting location without file, maybe this (citation from Windows Sripting Technologies (unfortunately broken now):

"The CurrentDirectory returns a string that contains the fully qualified path of
the current working directory of the active process."

The active process is for example the running HTA, so this will give the local path of the HTA file (without filename).

currentDirectory is a property of WScript.Shell, so you can use it with WshShell in your code, also to set working directory.
