File details

[Jaez]

I am trying to make my website produce a podcast for itunes with a number of
item entries and I could really do with help with the following
practicalities.


1) How can I determine from my webpage if a particular file exists on the
server.
In VB 6 I would have used something like Set fp =
CreateObject("Scripting.FileSystemObject"): If fp.FileExists....

I need something like
If fp.FileExists(http://mysite.com/files/thisfile.mp3) Then


2) Assumeing that the file exists then I need to know its length in bytes so
I can add this information to my podcast XML file

3) I now have my basic XML file template for this file type in an SQL
database and I can load that file to a variable in VB and replace various
placeholders with the required values.

What is the syntax for saving the contents of the string variable as a
file back on the server?

Thanks for all your help

1) See System.IO.File.Exists if the file is local. Despiste you used a URL
as it seems you say you would do this with fso and the site is named
mysite.com I assume this is a file that is on your own server. (if a remote
file you could issue a HTTP request).

2) Same System.IO.FileInfo gives you some details such as the length

3) Not clear. See the Replace statement ? (you want to replace a know
placeholder inside a template file ?). Using a XSL stylesheet to create the
XML file from particular data could be a cleaner option (or creating the XML
directly from the SQL Server)...
