I've stumbled into an issue related to retrieving a file name / path from an object handle, I can identify that the file handle is a handle for a file, but I'm stumped at getting the file name / path of which the handle is for, anyone know of any existing method implemented in autoit for doing this?

Currently I'm using winapiex function _WinAPI_GetObjectNameByHandle($hObject) to validate that it is indeed a file handle but I'd love to know of how to get the actual file location of which it belongs :oops:.

I've found this example but I'm not exactly fluent in moon-speak.

I mentioned this today in my LockFile UDF thread. Search WinAPIEx.au3 (it does all the moon translation for you) and then use _WinAPI_GetFinalPathNameByHandle.

ApudAngelorum,

WinAPIEx.au3 comes complete with a help file. Yahied has also taken the trouble to cite MSDN links where appropriate.

Agreed, he's spent alot of time improving a UDF I use practically everyday.

Works perfectly! Only problem is that the script freezes until I kill both instances of autoit3wrapper.exe and the script resumes operation as normal.

Thanks everyone.

Edit: Confirmed, for some reason the first instance of the autoit3wrapper.exe freezes my scripts operation until I kill it, but if I compile the script, everything works as expected. :oops:

Do you have a small reproducer so we can look at it. Also could you specify the version of AutoIt and SciTE4AutoIt3 you're using.

ApudAngelorum,

I've run into something like this before. You might try setting the handle variable to 0 or "" when you are done with it.

kylomas

Do you have a small reproducer so we can look at it. Also could you specify the version of AutoIt and SciTE4AutoIt3 you're using.

I'm sorry, this wasn't really something wrong with the autoitwrapper, the problem was that I was performing the tests on scite which seemed to directly interfere with the operation of all of its child processes, my bad.

I've just realised who you are, I'm sure you previous handle wasn't on top of your image before.

Just in case anyone is looking for help and ends up here regarding a similar issue and encounters a freezing script like me, the issue was really affiliated with system file object attributes.

File handles with these attributes should be avoided for some reason.

Like I said provide a small reproducer and then we can see if the problem is actually those attributes (whatever they may be without sifting through the MSDN.)

I'm sorry for the late response guys, I feel asleep right after that post, here is exactly what I was doing~

Yesterday I was sifting through yashides winapiex examples and noticed a particular function that would enumerate some of a processes open handles, it reminded me of a post by manko and monoceres, from which I took a deep look at how they were avoiding a freezing script, the end result was this.

My understanding of this is, if you're opening a file and getting a file handle when you open it, don't you already know which file you opened? Why are you trying to get the filehandle -> Filename link, you should already have that.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

True, ideally this information should ideally be stored in an Array (for example).
