XmlDocument and internet connectivity

[selvamarcadu]

Hi,

I am trying to load a xml file and modify a node value.

Dim configXml As XmlDocument = New XmlDocument
configXml.Load(xmlpath)

It works fine when i have the internet connectivity.But as i disconnected internet,I get the following exception pointing the line configXml.Load(...)

"The remote name could not be resolved: 'java.sun.com'"

Am i doing anything silly here?,I welcome your suggestions.


Thanks
selvam

Use Try-Catch to catch the exception, so your application doesn't crashes. It is expected that this throws exception when document is not available.
Try...Catch...Finally Statement (Visual Basic)

You can also check for network connection with My.Computer.Network.IsAvailable Property before attempting to load the url, but it is not guaranteed that the connection has internet, or that the document is available still, so a Try-Catch is also appropriate here.
How to: Check Connection Status in Visual Basic

Another approach would be to attempt to download the file first, then load document from file if download was ok, but there's only subtle differences with this.

Hi JohnH,Thanks you for your response.

I checked the xml file which is being loaded and commented the following line.
It works fine now .

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"[]>




Thanks
