Brute Force FileClose()

[J_Y_C]

I have a script that opens, copies and uses all kinds of temporary files, but I can't seem to get them to delete for the life of me. I have poured over and over anywhere I have a fileopen() or a filefindfirstfile(), and I can't find a single spot where I didn't close the handle.

To make matters more complicated, very often the file handle's name is built from a multitude of other variables. So, I guess I have 3 questions:

1. Is there a way I can just FileClose() ANY remaining open file?

2. If I cast 2 or 3 variables to another variable, and then FileOpen() or FileFindFirstFile() that variable, do I have to fileClose() just the one variable, or the lot of them?

3. Other than being poor practice, does it cause problems if I fileClose() something that I didn't need to?

All FileOpen() and FileFindFirst() statements will return a FileHandle which will ALL have to be closed.

There in no problem when you try to close a FileHandle thats isn't open anymore, but I fail to understand why you would ever lose track of the open files...

Bet'cha this gets it done:

Func _CloseAllFiles()
     Shutdown(6)
EndFunc

But you see the problem... The trouble to recode every FileOpen() to _FileOpenTrack() might be better spent improving you code to avoid needing this.

Thanks people. Psalty, I appreciate your help, and I feel bad that you spent time (not that I'm suggesting that it took you a long time) writing those functions for me, as I figured out my problem.

But perhaps I can help others by detailing what I did wrong. So, in my script I had some spots where I would fileopen() or filefindnextfile(), but I wouldn't always do it by casting it into a variable. I would just do, say,

DirCreate($IDs[$QN])
FileChangeDir($IDs[$QN])
FileOpen($IDs[$QN] & ".cue",2);opens the cuesheet
oÝ÷ Ù8^(ºWm¯+h~)^rZ,{Mú ;4ߤ

FileChangeDir($IDs[$QN])
$cueSheet=FileOpen($IDs[$QN] & ".cue",2);opens the cuesheet

,ÅÕ½ÐìµÀìÀÌØíàµÀìÅÕ½ÐìU%

and then closed it with fileclose($cueSheet).

And that totally fixed it!

Please understand, I've only been coding for about 4 or 5 months now. I'm working on my Java certification, but other than that have no education in code (though I do have an education, and work as a professional audio engineer). Since most of my textbooks are help files (though I do have a few Java books), and my instructors are strangers on forums, I find myself making a lot of stupid mistakes.

I don't typically rely on the kindness of strangers, but in this case it has worked quite well for me!

Thanks to everyone on this forum for all your interest and patience, I am most appreciative.
