question: FileOpen

[jsteng]

I have a question with regards to FileOpen.

Given:

• A text file @MyDocumentsDir & "\book keeper\logs\logs.txt" is used by another app; but I can open and read it.
• $FileHandle = FileOpen(@MyDocumentsDir & "\book keeper\logs\logs.txt")
• The code was successfully executed.

something happened afterwards:

logs.txt was renamed and a new logs.txt was created, or simply deleted

a: Will $FileHandle still point to the renamed file? or

b: Will $FileHandle point to the new logs.txt file? or

c: Will $FileHandle point to nothing at all?

Interesting.  I don't know, I'd have to start testing it.

I'd start by testing: a; If I ever had the time and wanted to know.

Lastly, according to documents:

The file handle must be closed with the FileClose() function.

Considering the file was renamed or deleted, SHOULD I still perform FileClose($FileHandle)???

Yes, I would close the file handle in all cases.

If a file handle is returned; It has been allocated and should be freed.  (That's how I look at it, but there are other symptoms, like the file staying in use)

Windows won't allow this as long as there is a program with a open handle to a file... Option C is probably your best bet if you force the operation.
