Best Way To Work With RSS Feeds
Jan 23, 2010
I am a CS grad, but haven't had much to do with programming since my school days as I went the BA route.Anyways, there are a few things that I do manually on the computer and thought that I could probably save time by creating an application for them.But I'm not really sure how to start.I'd like to be able to keep a history of Completed eBay listing so that I know when the price point is good and when it is too high.I noticed that eBay has an RSS feed, so I think I can do it. Just a couple of quick questions:
1 - Can I instruct VB.net to open a web browser and read an RSS feed, or would I need to manually do this myself and then run the application?
2 - What is the best way to work with RSS feeds? Should I convert the data into XML first?

how to convert rss feeds to datagrid in this fomat
<Row>
<Cell><Data ss:Type="String">Symbol</Data></Cell>
<Cell><Data ss:Type="String">Close</Data></Cell>
<Cell><Data ss:Type="String">Prev</Data></Cell>
[code]....
the values in the first <row> </row> of data are the column headings for the corresponding cells in the other <row> </row>considering that I can work with xml in the other format this is quite strange so any help will be needed.

I am working on a program which can list all news from a webpage ( url...), but I have problems to get the news. I know that it is possible to get the rss feeds where all the news are listed ( for this example it's url...) via XML to LINQ ( I need all links, titles and descriptions ), but I have no knowledge in it

I've integrated a bit of code into my project using Visual Basic, that reads RSS feeds. It works absolutely fine. I did however intend it to read Facebook notifications to users of my program. The idea was, if you go on Facebook, clikc Notifications, click See All Notifications, click via RSS, you get an RSS feed right there. When I use the address in the address bar for my project's RSS reader though, I just get an error.
Like I said, it works for other feeds, just not working for Facebook notifications.

I have a requirement to consume only the latest two rss feeds (using .NET) to reduce latency in reading RSS. I found plenty of examples to consume RSS. However, I did not find any to limit the feeds being read. And, this is not for a windows forms application.

This seems to be a great article by Scott Mitchell for creating syndicated feeds in ASP.NET 3.5. The problem for me is that it uses C# and Linq, which I'm not as sharp on at the current time.[URL]...Does anyone know where an example might exist for the System.ServiceModel.Syndication namespace that can produce a syndicated feed like this article using VB.NET and a SQLConnection object?
I've looked around and every example seems to be produced in C# and Linq (which is probably a testament to my need to learn them soon rather than later).

Public Class Form1
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim rssUrl = _[code]....
I get a Null Reference Exception on the next to last line of code. (Object reference not set to an instance of an object.) The line that begins with "Temperature.Text = .......". If I remove the last two lines of code the program works.If I edit the last two line to read "yweather:condition/@temp, and yweather:condition/@date" instead of what's shown above, the program works. I think it has something to do with the XML NameSpaceManager not being setup correctly.

I have a form that contains a RichTextBox control that I have set to multiline. I also have a menu item that allows the user to save the contents of the RichTextBox as either a .rtf document or a .txt document. Here's the code I'm using so far:
If sfdSaveTextFile.ShowDialog() = DialogResult.OK Then
m_strDocFileLocation = sfdSaveTextFile.FileName
m_strDocFileExtension = System.IO.Path.GetExtension(m_strDocFileLocation)
[Code]....
into the RichTextBox control (rtb) then saves as a text file this would save the text file like: "TempTemp"
Is there any way to write to the text file with line feeds included?

Is there any way, in my project's properties, to put a carriage return or a line feed in the Description field of the Assembly Information dialog box, in which the Description information would then appear in the description field of the about box of my project?

I am monitoring 12 video feeds from video cameras. Now I have more than 12 cameras, I have 134. But I will only monitor 12 cameras at a time. By Monitoring I mean, I have 12 small video screens on the form that I can see the video. The way I know which cameras are active, so I can monitor them is by a boolean value in a sql database. I run a Store Procedure in my program, and spit out the results in a XML file. I then read the XML file in a loop. This XML file will have a list of the camera names I need to monitor.
So that is for 12 video feeds. Now, I want to have a NEXT or FORWARD button on my monitor form. So when I click this it will give me the next group of cameras, 13 to 24. Now if I only have15 cameras that are active, that means the first group is 1 to 12, then the second group is 13 to 15 cameras. So I will only have 3 to monitor on the second grouping. One thought I had was to have another field in my table to mark as already as an active monitor, so when I run the SP, i will not select that row. But I need to select 12 at a time. Or I can make a number of xml files, one xml file for each grouping of 12, but I need to figure out how I can select the next group without re-selecting the first group. I have no code at the moment, I'm on my non-programming computer.

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

I created a windows form application using Visual Basic Express Edition 2008 but I did not know I could not use it on the web, which is what I wanted but being new to VB I just got a lot of headaches trying to figure this out. It works fine as a windows app but now just recently I installed Visual Web Developer 2005 to so I could create a web application from the windows app.
It is a simple windows application of a datagrid but now I want to run the same design application I made in Visual Basic to Visual Web Developer Express 2005. Is this possible? And, what do I need to do? I have all of the associated files in my project folder in Visual Basic Express folder.

how does look-up work in Visual Basic, I have done research on this but it does not explain. I have a Form1 called( Booking form) with 2 ComboBox's and 1 TextBox. each called (Destination_FromComboBox) and (Destination_ToComboBox) and (FareTextBox)and another form2 called (Fares Form) with 3 TextBox's each called TextBox1 (FromTextBox), TextBox2 (ToTextBox2), TextBox3(FareTextBox).So when I select (Booking Form) and Insert or select a Destination from (Destination_FromComboBox) and Insert or select a Destination To (Destination_ToComboBox) I want to read from (Fare Form/Fare Table) and give me the fare in FareTextBox on the Booking Form. Also on the booking I have 3 Radio Buttons
(RadioButton1 = 4 Seater Car, Normal Fare)
(RadioButton2 = 6 Seater Car, Time & HalfFare)
(RadioButton3 = 8 Seater Car, Double Fare)
But there is also a time Issue as well:
If the time is Between 05:00 & 23:59 then normal time should be used
If the time is Between 00:00 & 02:00 then time & half should be used
If the time is Between 02:00 & 05:00 then Double time should be used
I have watched loads of video's and looked through forums and other codes for the combination of the above, without success?

I have this great way to use VB6 I treated my project like a .exe file.Say I want to work on c:work directory.I just save as the .vbp file to c:work directory
All the other files (.frm,.bas,.cls) files are in a special directory called library ALL of my .vbp files, in c:work1, c:work2, c:work3 refer to that one same directory.How can I do that in vb.net?
Why this is important? Bugs always happen all the time. If I just run .exe file, when bug happen, I cannot do a thing. However, if I run the project file and run the program in debug mode, when bug happen I can figure out what happen.

I am trying to get a percentage that just does not seem to work.I am using WMI to get the Total Physical memory of my system and then the Free Physical Memory. Then get the percentage.
2147483648 - Total Memory
838028 - Free memory
According to Task Manager my physical memory is 59%. This is the code I am using but I can not get 59% or 41% that is free.
temp = FM/TM
temp = temp * 100
percent = FM * temp

I have a simple application:Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
#If DEBUG Then
lblDebug.Text = "Debug"
#Else
lblDebug.Text = "Not in debug"
#End If
Now when I run it in VS, it prints "debug" like it should, but if i run the .exe, it still prints "debug". What do i have to do to get this to work right?

I am modifying a couple of fields of a datarow and immediately calling AcceptChanges on this datarow. Technically, after calling AcceptChanges, the RowState of the datarow must be "Unchanged", but it is still "Modified". Why is this so?
