I am trying to request a XML file Using VB.net and load it in my application.I have been able to use a JavaScript in the past which uses XMLHttpRequest but now I am trying to create a application that will allow me to request a XML file and parse it.In the past I have used the following JavaScript code to request and show the reply in a textarea:\[code\]<html><body><button onclick="send_command()">GET</button><textarea id="test1" name="test1" cols="90" rows="30">XML file will be displayed here</textarea><br><script type="text/javascript"> function send_command() { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("test1").value=http://stackoverflow.com/questions/14597790/xmlhttp.responseText; } } var url ="http://192.168.0.50/my_xml_file.xml"; xmlhttp.open("POST",url,false,"admin","admin"); xmlhttp.send(); }</script></body></html>\[/code\]But now I am trying to do the same thing but using VB.net (2012) as a windows Application.After doing a quick Google on this, I have found the following code:\[code\]' Create a WebRequest to the remote siteDim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("http://192.168.0.50/my_xml_file.xml")' NB! Use the following line ONLY if the website is protectedrequest.Credentials = New System.Net.NetworkCredential("admin", "admin")' Call the remote site, and parse the data in a response objectDim response As System.Net.HttpWebResponse = request.GetResponse()' Check if the response is OK (status code 200)If response.StatusCode = System.Net.HttpStatusCode.OK Then ' Parse the contents from the response to a stream object Dim stream As System.IO.Stream = response.GetResponseStream() ' Create a reader for the stream object Dim reader As New System.IO.StreamReader(stream) ' Read from the stream object using the reader, put the contents in a string Dim contents As String = reader.ReadToEnd() ' Create a new, empty XML document Dim document As New System.Xml.XmlDocument() ' Load the contents into the XML document document.LoadXml(contents) ' Now you have a XmlDocument object that contains the XML from the remote site, you can ' use the objects and methods in the System.Xml namespace to read the documentElse ' If the call to the remote site fails, you'll have to handle this. There can be many reasons, ie. the ' remote site does not respond (code 404) or your username and password were incorrect (code 401) ' ' See the codes in the System.Net.HttpStatusCode enumerator Throw New Exception("Could not retrieve document from the URL, response code: " & response.StatusCode)End If\[/code\]However when I run the code above in VB.net I get an error:
I can't seem to work out why this error is happening.Does anyone know what the error above means or better still is the VB.net code above going to do what I am trying to do? (My XML file requires a username and password to view the XML)
