uri class in .net works only if http://, https:// or file:// is used on the beginning of an address.

Sure, but there should be an error somewhere.

Little screenshoot under spoiler.

Can you share that link of that xml web or any code ?? 😅 😅 😅

If I an not mistaken, you will need to create a stream that fetches the XML file from a specific URL.

Example Code:

Code 
Dim URLString As [String] = " http://localhost/books.xml"

Dim reader As New XmlTextReader(URLString)

Maybe because you have an empty variable?
On your button mnuOpen, you need to browse first for nothing before the variable "Filename" get the data.

RE: URI Format not supported - aGFjaw-- - Oct 29, 2017

Here is full code.

Code 
Imports System.Xml

Imports System.Text

Imports System.IO

Public Class MainForm

  Dim mFileName As String = String.Empty

  Dim mDocument As XmlDocument = Nothing

Private Sub mnuOpen_Click(sender As System.Object, e As System.EventArgs) Handles mnuOpen.Click

  If OpenDialog.ShowDialog = Windows.Forms.DialogResult.OK Then

            'FileName = OpenDialog.FileName

            FileName = "http://vb.net-informations.com/xml/img/product.xml"

            LoadFile()

  End If

End Sub

Private Sub LoadFile()

  If mDocument Is Nothing Then

    mDocument = New XmlDocument

  End If

  Dim Content As String = File.ReadAllText(FileName, Encoding.Default)

  mDocument.LoadXml(Content)

  rtbXmlSource.Text = Content

  trvNodes.Nodes.Clear()

  FillTreeView(trvNodes.Nodes, mDocument.DocumentElement)

End Sub

Private Sub FillTreeView(TreeNodes As TreeNodeCollection, Xml_Node As XmlNode)

  Dim NewNode = TreeNodes.Add(Xml_Node.Name)

  NewNode.Tag = Xml_Node

  For Each Node As XmlNode In Xml_Node.ChildNodes

    FillTreeView(NewNode.Nodes, Node)

  Next

  trvNodes.ExpandAll()

End Sub

Private Property FileName As String

  Get

    Return mFileName

  End Get

  Set(value As String)

    lblFileName.Text = value

    mFileName = value

  End Set

End Property

Private Sub trvNodes_AfterSelect(sender As System.Object, e As System.Windows.Forms.TreeViewEventArgs) Handles trvNodes.AfterSelect

  If trvNodes.SelectedNode IsNot Nothing Then

    PropertyGrid1.SelectedObject = trvNodes.SelectedNode.Tag

  End If

End Sub

End Class

Its a good idea to download that file in Temp folder and then read it from XmlReader and on

OnFormClosingEvent delete that xml file from Temp directory.

RE: URI Format not supported - aGFjaw-- - Oct 29, 2017

Yes, I thought to do so, but I would like to read it directly from the web.

RE: URI Format not supported - v.e.n.o.m - Oct 29, 2017

if you can share that link then i will create and upload the project.

RE: URI Format not supported - aGFjaw-- - Oct 29, 2017

Sure :

Download

Scan

Thanks for releasing it to us

RE: URI Format not supported - CoderEX - Oct 29, 2017

You would replace the OpenFileDialog code with the code I provided up top. You need to create a stream that requests/reads the file from a specific URL.

RE: URI Format not supported - aGFjaw-- - Oct 29, 2017

Already tried but it does not work.
I also tried with WebClient.
There should be more stuffs to edit, something I don't understand.

What does your current code look like? I looked at the last code you posted, and it seems like you are still using OpenFileDialog.
