The computer eats a slash as a special character. Putting another slash
in front escapes it so it doesn't get eaten.

I had a real problem with this.
The solution was convoluted and had to do with some obscure issue I
don't quite remember.

Searching the archives, I found my old post.

This worked with javascript.

Dunno. :)
Don't use HTAs enough.

If you don't mind using vbscript or know how to convert it to JScript,
this group is pretty good.

This is true within a JavaScript.
Not true within a VBScript.
Both Scripting languages can coexist within the same HTA and can call each others subs(vb) and
functions(vb/js).

The following utilizes the VB MsgBox to capture a result of a keypress.

To be clear here: The Windows File System (which both JScript and VBScript can
access) uses single backslashes to partition pathnames.

JScript (like all C-family languages) uses backslash as an escape character in
strings. Backslash was chosen for this purpose because it is rarely used.
Unfortunately, Paul Allen made a horrendously bad choice when he chose \ for the
pathname partition character for MS-DOS. This, like many other inexcusable
design errors, was carried forward into Windows.

The JScript compiler sees the source text

"F:\documents\r andom text\realpongfa q.txt"

as containing the escape sequences

\d \r \r

To avoid that wrong interpretation, the backslashes themselves must be escaped.

"F:\\documents\ \random text\\realpongf aq.txt"

Strings that come from the DOM or from the user do not need to be escaped.

No, in vbscript, it eats double quotes. :)

Well, going from Dos 1.0, which had no directory structure (progs and data all in the root of the
boot drive) to dos 2.0 which had directories, I would guess they fancied themselves pretty smart
cookies at the time.. :^)

Also, if you have VB, you could write a wrapper ActiveX around the MsComDlg control and have an
actual File Open dialog box. There are many freebies of this on the web, but most people wouldn't
trust a 3rd party control and it is little work to roll your own. It adds a nice touch on your in
house app and of course could be reused many times...

One thing to note is that the FSO (aswell as many windows
applications/components) allow you to use / as an alternative to \ so
you can do:

fso=new ActiveXObject(" Scripting.fileS ystemObject");
alert(fso.fileE xists("C:/windows/fonts/arial.ttf"));

This may not be all windows O/S's so test on your own machine of
course!
