Problem with loading XML file in VB.NET 2003

[Guest]

Hi All,

I am using VB.NET 2003 and having problems with loading an xml file. Here's
my code:

Public Sub LoadXML()
Dim xmlDoc As New Xml.XmlDocument
xmlDoc.Load("C:\Databases.xml")

'more code follows here

End Sub

When I get to the line that loads the databases.xml file, I get this error
message:

An unhandled exception of type 'System.NotSupportedException' occurred in
system.xml.dll
Additional information: FileStream was asked to open a device that was not a
file. FileStream's constructors that take a String will only work with
devices that are really files. If you need support for devices like "com1:"
or "lpt1:", then call CreateFile yourself then use the FileStream
constructors that take an OS handle as an IntPtr.

Any ideas why? the file C:\Databases.xml does exist.

Any ideas why? the file C:\Databases.xml does exist.

Does it open fine with internet explorer? Also, can you load other Xml
files in this same application?

Thanks,

The help text says that the overloaded Load method that takes a
character string as the parameter must be a URL. I belive that is
different from a file path. At any rate, I have successfully loaded
XML files using the overloaded Load method that takes a FileStream as
the parameter. Of course, you have to initialize the FileStream to the
XML file to open first.

Thank you, Seth and zacks for your responses. I tried my code in a different
computer and it worked. I might just try re-installing the .NET framework
and Studio on the other computer and see how it goes.

Thanks again.
