Retrieve fully qualified .lnk file's target in script?

[brianm]

Hi Leo,
in this item :
How to open a shortcut(.lnk) from a command - #10 by Leo
you mentioned that

No filename code, but scripts can look up shortcut targets, fwiw

I'm trying to create a column-script that will
- return a shortcut's link if that is the file extension
- and the file's path if the current tab is a collection

I've attached the script, inline, below. I was trying to use the ScriptColumnData.columns object, perhaps erroneously, on line 68+1 of the script.

Could you pls provide a code snipped by which a script can return that information?

Many thx, Cheers, Brian

soughtValue = scriptColData.columns('target').value;

scriptColData.columns is the columns which your script has added and can fill out. You can't use it to look up the values of other columns. (It's essentially an output of your script, not an input.)

To get the target of a shortcut (.lnk file) in JScript, you can do this:

var sh = new ActiveXObject("WScript.Shell");
var sc = sh.CreateShortcut(scriptColData.item.realpath);
var targetPath = sc.TargetPath;

A fuller example can be found here:

Columns: Extensions for Shortcut Targets

Overview: This script adds a column which is like the built-in Ext (extension) column, except that if the file is a shortcut it will show the extension of the file the shortcut points to, instead of the actual shortcut extension of "lnk". Installati…

To get the target of a shortcut (.lnk file) in JScript, you can do this:

var sh = new ActiveXObject("WScript.Shell");
var sc = sh.CreateShortcut(scriptColData.item.realpath);
var targetPath = sc.TargetPath;

Isn't that the same as item.metadata.other.target?

Should be the same result. Not sure which is faster without testing it.
