Unable To Cast COM Object Of Type 'System.__ComObject' To Class Type 'System.Xml.XmlNode'
Jul 30, 2009Code: Dim dom As New DOMDocument30 dom.async = False
dom.Load(serverAddress & "/App/filelist.jsp?type=content")
For i = 0 To dom.childNodes.item(1).childNodes.length - 1 downloadfile(dom.childNodes.item(i), mcount, currentpath) Next
The above code is activated upon clicking of a button. i have the server address declared. and using the domdoc to load the jsp file to generate the xml data. and using for loop, i call the download file function which accepts the following parameters
Code:Public Sub downloadfile(ByVal domdoc As Xml.XmlNode, ByVal totalcount As Integer, ByVal currentpath As String)
The totalcount and currentpath work fine, but when i pass in the dom.childNodes.item(i) , error pops up.

Calling Web Service Which Returns XML Data
Aug 11, 2011I have been given the task of calling a web service which returns an xml data feed which I am doing like so:
For Each r As DataRow in SomeDataTable
Dim msFeed As String = string.format("[URL]?param={0}", r!SOME_VAL)
Dim x As XDocument = XDocument.Load(msFeed)
Next
This is all fine but as you can see x just gets overwritten with every iteration. What I need is create an xDocument and add each feed from my loop but I am unsure how to proceed.
Solution
Dim xAllFeeds As XElement = New XElement("Feeds")
For Each r As DataRow in SomeDataTable
Dim msFeed As String = string.format("[URL]?param={0}", r!SOME_VAL)
Dim x As XDocument = XDocument.Load(msFeed)
xAllFeeds.Add(x.Root)
Next
Silverlight Service Callback Returns Null
May 31, 2012I'm trying to get data with the methods below and I get null response and can't figure out why. I'm just trying out a different way of using a wcf service from silverlight and I don't understand something that I should.[code]...
The employee object will stay null. If I put a break into the service call and follow through the code it finds the correct record from the database and the return statement shows an object with the correct data but still the employee object in silverlight side will remain null.

WNetGetConnection Returns System Error 487
Jun 3, 2009I've been trying to get the UNC path for a mapped drive in a web application written in VB.net 2005. I was able to get this code working[code]...
I tested this code out in a test application - just a simple web page. But when I plug the code into my actual project, it doesn't work. In my testing of other examples, I figured out that WNetGetConnection returns a system error of 487 - ERROR_INVALID_ADDRESS.

Query - Access Db Returns Null After Changing Operating System Date?
May 8, 2012I have a select statement which was returning the required values but when I changed the OS date from English(US) to English(UK), it now returns null. I believe the problem is concerned with date since in the query am selecting values where the date from the database is the same as the date in a combobox but I don't know what else I can do. It almost looks like the dates in the combox and in the database are not the same and yet the date in the combobox is actually retrieved from the database and has been returning values fine until I changed the system date format.Here's my select command:
cmd4.CommandText = _
"SELECT sum(brought_qtty), recieved_qtty from brought_coffee, centre_weigh where brought_date=#" & _
