Hello,
I want to list and write files with jscript on HTML files on a pocket pc
with CE 2003.
These are local files on pocketpc. So PIE should no complains about security
issues.
On standard "Windows" Internet Explorer, we should use the ActiveX
"Scripting.FileSystemObject" and so on objects.
What I understand (and what I found on the web), is :
On pocketpc this ActiveX does not exists. It is replaced by something like
"FILECTL.FileSystem" which is found in a DLL called MSCEFile.dll and must be
registered with a tool like regsvrce.exe
I first download EVC and SDK 2003 and I dont find this stuff.
Then I download SDK 2002, and I found the DLL.

But this does not seems to work with a dumb example, found on newgroups,
like :

<html>
<head>
<script language="JScript">
function pippo(){
alert("init");
var fso;
var f;
fso = new ActiveXObject("FILECTL.FileSystem");
alert("fso ActiveXObject");
f = new ActiveXObject("FILECTL.File");
alert("file ActiveXObject");
f.Open ("\\test.txt", 2);
alert("Open");
f.Close();
alert("Close");
}
</script>
</head>
<body onload="pippo()">
<p>body</p>
</body>
</html>

Bad dll registration ? bad script ? or incompatibilities with 2002/2003 OS
versions ?
Have you some ideas.
What is the corresponding DLL for SDK 2003 ?
Is anyone has better examples to show how to use these activeX in jscript ?

thanks.

I'm not sure about the device, but now a days, I think you can't even do that
in the desktop platforms due to security concerns

TH is right - there are huge security concerns with these objects. If the
desktop disabled it, they had a good reason. I'm sure the web page you
write to manipulate the filesystem objects will be well-behaved. But
suppose that a user ends up getting redirected to a site that is malicious
and does bad things with the filesystem object?

WinCE does not have support for these objects. I think embedded visual
basic may have something like FILECTL.FileSystem, though I'm not sure. I'm
pretty sure you can't run that from PIE -- actually due to security issues I
really really hope you cannot, at least without a lot of hacking.

On the newsgroup microsoft.public.windowsce.embedded.vb, post thread [asp]
read file on windows ce, someone asked for the same thing and a fellow
actually said he implemented the File System Object. You may try contacting
him and seeing if he'll give you the FSO code. Be sure to ask him if it is
safe for PIE. (There's ways you can make it more safe, but I forget the
details.) I didn't gripe on the other thread about security because the
fellow is using FSO on an ASP device where CE is the Web Server and hence he
has control over what he runs, unlike the PIE case.

Standard MS legalize is that I can't vouch for the fellow with the FSO, so
if you have problems don't complain to us. It's lame I have to say that
because I'm sure you knew it anyway, but lawyers are lame too.

Finally, I found a solution on the web.
It is the freeware "axgate" from www.newobjects.com
I would prefer some cleaner and integrated solution from MS, but ...
thanks for your responses.
