MapPath invalid character error

[Supertzar]

Hi,
I'm trying to use MapPath on a folder named with a comma in it:

xmldoc.load Server.MapPath(Request.QueryString("fname"))

where the querysting is something like "fname=this, that/this, that.xml".

I'm sure it's the comma, because if I remove it and rename the file
and folder, everything works.
I believe that a comma is a valid character in a folder or filename,
so why does MapPath barf on it?
Is there any way around this still using MapPath?
Can someone point me to a source with a list of the valid characters
the MapPath accepts?

Thanks,
Supertzar

Hi Supertzar,

From my research it looks like this is a known issue, Microsoft has
known for years, but no fix is available.

What you'll have to do is break the path down in code and only do
Server.MapPath on the portion you know is safe.

What I had was a file name for which I needed to know the absolute
path on my disk, so I did this:
strFullPath = Server.MapPath(".") & "\" & strMyFileNameWithCommas

Hope this helps.
David

I'm having the same issue. My filename contains a
comma. Have you found a workaround using server.mappath?
