Can someone please confirm this behavior?

[Aaron Bertrand - MVP]

Based on a complaint that one of my articles just links to the MS
documentation, I'm writing a tutorial on FileSystemObjec t. However I'm
currently getting stalled by this bug.

Environment: Windows Server 2003, IIS 6.0, VBScript 5.6, all windows and IE
update patches (to my knowledge).

From
msdn.microsoft. com/library/en-us/script56/html/jsmthcreatetext file.asp

The FileSystemObjec t doc for CreateTextFile states for the overwrite
parameter:

"Optional.
Boolean value that indicates whether you can overwrite an existing file. The
value is true if the file can be overwritten, false if it can't be
overwritten. If omitted, existing files are not overwritten. "

I believe "If omitted, existing files are not overwritten" is an inaccurate
statement. The following code definitely overwrites the file.

<%
set fso = CreateObject("S cripting.FileSy stemObject")

set fs = fso.createTextF ile(Server.MapP ath("foo.txt"))
fs.writeline("f oo!")
fs.close: set fs = nothing

set fs = fso.createTextF ile(Server.MapP ath("foo.txt"))
fs.writeline("o verwrite!")
fs.close: set fs = nothing

fso.close: set fso = nothing
%>

According to the doc, calling CreateTextFile( filename) should be equivalent
to calling CreateTextFile( filename, false). However when I do the former,
it overwrites the file (try it out, and examine foo.txt). When I do the
latter, I get the following error:

Microsoft VBScript runtime error '800a003a'
File already exists

So, (a) is the documentation incorrect, (b) is FileSystemObjec t behaving
incorrectly, (c) are the docs I'm looking at outdated, or (d) is there
potentially some configuration issue in my environment that makes this
script misbehave (e.g. does it work right for you)?

I just want to make sure that if the behavior is correct and the docs are
wrong, or if the docs or correct and the behavior is wrong, I convey the
correct location of the bug. :-)

Thanks in advance.

(BTW - Same behavior on XP Pro.)

Yep, same thing here. With no argument passed, file is overwritten. With
False passed, I get the "file already exists" as expected, and with True, it
behaves as though it was omitted.

I'll pick a.
I tried this on W2K Server with WSH5.6, btw.

Same here.

Notes:
1. Here's someone else who encountered the same thing. He didn't get an
answer either.
http://groups.google.com/groups?thre...3B%40hydro.com

2. I declared but did not initialize a variable "a" and passed that as
the overwrite parameter and it behaved as advertised in the
documentation (i.e.. File exists error was thrown). Perhaps the
CreateTextFile method is dealing with the absence of the argument in a
non-standard way. Pure conjecture on my part.

A quick look at the Microsoft Scripting Runtime (scrrun.dll) with the Object
Browser show that the second parameter is True by default:
Function CreateTextFile( ByVal FileName As String, [ByVal Overwrite As
Boolean = True], [ByVal Unicode As Boolean = False]) As ITextStream

Member of Scripting.FileS ystemObject

Create a file as a TextStream

From this, we can say that the documentation is clearly wrong. This is on
XP with VBScript 5.6.
