Xml - Another About Getting Entries From StackOverflow Atom Feed
Dec 18, 2009
I feel like an idiot for asking this question again, as I know it's been asked several times. I cannot for the life of me get this code working even with the answers that have already been provided, so I'm hoping that by offering my current code, someone can help me determine where I'm going wrong:
Dim RSSReader As New Xml.XmlTextReader("http://stackoverflow.com/feeds")
Dim RSSDoc As New Xml.XmlDocument()
Dim NSMgr As New Xml.XmlNamespaceManager(RSSDoc.NameTable)
NSMgr.AddNamespace("atom", "http://www.w3.org/2005/Atom")
RSSDoc.Load(RSSReader.GetRemainder())
[Code]...

I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box
' declare variables
Dim strName As String
Dim strArtist As String
Dim strPrice As String

I am trying to figure something out. I have an application in which I am adding the ability to consume a feed. I have no problem with the feed itself, but my problem is how can I mark certain items as 'read'? The only thing I can thing of is to read the feed into a database. In this database, I add a column for 'read' which I update when the user has read the article. Then each time I retrieve the feed, I compare the feed to the database and only load new items into the database.

I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?

I have a program that uses Lucene.net in ASP.NET (VB.NET), when you search a term, results are stored in the Lucene.net data structure "hits".I want to read out the hits into an data structure and work with them, after that I display them in a DataGrid.By searching a term with a lot of results, often (but not always) there is an error by following code :
For i = 0 To results - 1 Step 1
Try
Dim tmpobj As New object_hit(( _
hits.Doc(i).Get("title") + _
[code]....
I checked the server; it's a dwh server and has no problems to execute the program.At first I used a ReDim Array, but now I use a List(Of T).

[URL]notice that the tag topic count for C# is in excess of 8900 while the vb.net tag topic count is sitting at 1019. Does this mean that there is a shift towards c# as a .net language of choice. the only reason I decided to build some applications for work using c# was that I like curly braces - after all vb has the same language support as c#, doesn't it so there should be no advantage to choosing one over the other; other than curly braces;)

I have an StackOverflowException in one of my DB functions that I don't know how to deal with. I have a SQLite database with one table "tblEmployees" that holds records for each employees (several thousand posts) and usually this function runs without any problem.
But sometimes after the the function is called a thousand times it breaks with an StackOverflowException at the line "ReturnTable.Load(reader)" with the message: An unhandled exception of type 'System.StackOverflowException' occurred in System.Data.SQLite.dll
If I restart the application it has no problem to continue with the exact same post it last crashed on. I can also make the exactly same DB-call from SQLite Admin at the crash time without no problems.
Here is the code:
[Code]...
When crashes, the reader has "Property evaluation failed." in all values.I assume there is some problem with allocated memory that isn't released correctly, but can't figure out what object it's all about. The DB-connection opens when the DB-class object is created and closes on main form Dispose.
Should I maybe dispose the mycommand object every time in a finally block? But wouldn't that result in a closed DB-connection?

I have a directory of images that reside outside the context of my web application that I need to serve to the user. Currently I'm using an IHttpHandler to serve the images and using some javascript to navigate through a set of images (the navigation is primitive for now). I followed examples for using IHttpHandler to serve images closely but when I view the images in firefox the browser hangs and when I view in IE I get a "Stack overflow at line: 0".
Code for the IHttpHandler
Public Class ShowImage : Implements IHttpHandler

I understand that this is bad programming practice and redundant coding but I am curios.
I am simply counting a number up to 9999999 in a while loop. The Add() function simply increases that number and prints it out.
Inside the Add() Function I call the Add() function.
My program successfully prints out 12000ish numbers before I get a StackOverflow Exception.
So my question = Is there any way to ignore this error and keep counting?
I have tried On Error Resume, Try/Catch, and throw
My code is as follows.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
While number1 < 9999999

I have 2 classess. Role and User like this
Role
Public Class Role
Public Property RoleID As Integer
Public Property CreatedBy As User
[code]....
The situation is like when we create roles, we will save who created this role. So i have a CreatedBy Property of type User. Similarly when we create a User, we will mention what role the new user belongs to .So i have a property called "Role" of type "Role". This circular reference giving me StackOverflow exception as its recursive when i create an object of User class.How do i handle this ? should i restucture my entties ? how ?

I have done some reading and it seems that this error comes from recursive calls but I have not done anything in my form_closing handler except for call me.close, that's it.
So I don't understand how this exception has entered my project. All of my data and functionality is still working as I expect. It just seems to throw this exception when I try and exit my project.
what I could check to prevent something like this from happening?

I am having trouble extracting the response XML from an XMLHTTP request.
I am currently subscribed to a RSS Feed, [URL]
The code I have only retrieves the first 20 posts rather than all of the 133 posts that I see.
I am linking the problem to cookie settings. I seem to think that the request I am sending is not incorporating the cookie settings that I have on my computer.
You may have to subscribe to a feed to extract more than 20 posts. The standard for RSS feeds (without subscriptions) only allows a user to view 20 posts, HOWEVER, with subscription, the feed's number of posts grows.
Provided is the code I have implemented so far
Sub tester()
Dim xmlreq As MSXML2.XMLHTTP
Dim xmldoc As MSXML2.DOMDocument
Dim strurl As String

This I slikely far fetched but if there is any way to bring an RSS feed into the picture for my launcher for world of Warcraft that I am making customly, (Yes I know the regular wow launcher is good but I have a custom one I made with command buttons that lead to forums and homepage and play retail wow along with a private server command button)

I am reading data from an API feed and saving the chunks into files. When the files reach 2 MB I start a new file and write to that file. What happens now is that an entry (<entry></entry>) can get cut off at the end of a file and continues into the new file. I try and reconstruct the files by taking the last entry and combining it with the first entry of the next file but this is tedious handling the data transmission and file creation.
Do
timestamp = DateTime.Now
numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)
If numbytesread > 123 Then
'timestamp = DateTime.Now
responseData = Encoding.UTF8.GetString

How do I consume my WordPress blog's RSS feed to display my latest blog posts on my homepage? I ran into the following piece of code to do this:
Function GetRSSFeed(strURL as String) as DataTable
'Get the XML data
Dim reader as XmlTextReader = New XmlTextReader(strURL)
[Code]....
But it errors out at this line: 'ds.ReadXml(reader)' with the following error:
A column named 'comments' already belongs to this DataTable.
Perhaps it doesn't work since this code is from 2003? Does anyone have a working code sample?

I have never touched RSS feeds before.
What would I need to do in order to set my page up so that it can get a RSS feed onto the page?
I have a page that reads information from a database through a repeater control
<form id="form1" runat="server">
<asp:Repeater ID="myRepeater" runat="server">
<ItemTemplate>

Is it possible to set up a RSS feed to this repeater control?

I need to create a application in vb.net that puts out those cool <<Subscribe to ical>> links, which I can prefill with our events and milestones. While I have figured out I need to use DDay.ical.dll to get the events into a .ics file, I am not clear about how to get these to publish. I was thinking of using an RSS feed, but that defeats the purpose of using icals and would require a RSS to ICal converter,which seems unnecessary.
