[Help] Full paths / short paths by alexp2_ad on 07-05-2006 at 04:55 PM

Is there any way I can convert a short path into a long one in JScript?  I have a function that returns:

C:\PROGRA~1\MOZILL~1\FIREFOX.EXE

But I need the full proper path, I've search and searched, but I'm outta ideas. :(

Anybody?

you will want to use GetFullPathNameW api if i remember correctly

I was trying that, but it seems to require I pass it some StringBuilder type which doesn't seem to exist in JScript or something.  If you could show me an example, that'd be very useful. :)

Again I am at work can't test it

code:
function ConvertPath(sString){
    var MAX_PATH = 260;
    var sBuffer = Interop.Allocate(2*(MAX_PATH)+2);

    Interop.Call('kernel32', 'GetFullPathNameW', sString, MAX_PATH, sBuffer, '');
    return sBuffer.ReadString(0);
}

Weird, that actually returned a string, unlike all my efforts, but it was the same string I put in.

Did you use GetFullPathNameW or GetFullPathNameA?
RE: [Help] Full paths / short paths by alexp2_ad on 07-05-2006 at 05:34 PM

Used GetFullPathNameW as you said.  Just tried GetFullPathNameA and it returned a bunch of chinese characters. :S

Ya because Javascript uses WChars so any API that has the ability of using Ascii or WChars you need to use the WChar so it is processed properly.

You might now have created your databloc properly to hold the amount of data.

wrong function matty :P

code:
function ConvertPath(sString){
    var MAX_PATH = 260;
    var sBuffer = Interop.Allocate(2*(MAX_PATH)+2);

    Interop.Call('kernel32', 'GetLongPathNameW', sString, sBuffer, MAX_PATH);
    return sBuffer.ReadString(0);
}

No, I said it returned the same thing I put in. :S

GetLongPathNameW works.  Thanks for the help. :)
