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 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?
i trying to display an rss feed but i dont think im using the right object as the webbrowser object does not work. ive tried several other objects but to no avail. is there a specific tool i should use or is it my code?

View 4 RepliesI'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.
View 2 RepliesThis 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).

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?

I'm stuck with .Net Framework 2.0, so no Linq or lambda expression goodies for me. Also I want to include the code in my custom library and not just reference it. Can anyone point me to some good library or code.
I just need to parse and not evaluate the expression and find what tokens are in use. After finding the tokens I need to change the expression string before parsing, like if the function ORGVAL is used then the parameter passed has has to be prefixed by an underscore. Like ORGVAL(BAS) will transform to ORGVAL(_BAS). Some functions can have tow parameters like ORGVAL(BAS, "2012/12/31") and this will transform to ORGVAL(_BAS, "2012/12/31")
NOTE: IF THERE ARE OTHER WAYS OF DOING IT PLEASE LET ME KNOW. I WOULD LOVE TO AVOID A PARSER AND LEXER.
Need to get length of a string minus the line feed chars and came up with this. Is there a better/more efficient way?

End Function
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?
View 3 RepliesI 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 app that the user selects information and it writes to an XML file. The user can increase and decrease the information in the XML file so it is dynamic. The other app reads the xml file and uses it to complete tasks. Since the XML is dynamic my code needs to account for that. Right now I have only allowed the XML to have up to four values in a certain node, I would like to allow more but I will need to increase the Select Case function.[code]

View 3 RepliesI may be getting in way over my head, but here it goes. I am developing a small application for use on a helpdesk. The application will be installed on the client pc's and will be used primarily by the end user to assist the technician on the phone if the user's pc is offline or inaccessible. One part of the application gives the user their IP address, DNS address, DHCP address, and gateway address. I have it to where it will put all of those in the corresponding fields inside a form, but it does not work correctly outside of a domain. Outside of a domain it only gives the IP address. I am sure it is probably how I coded it, but I cannot think of any other way to get that info in a user friendly way. Is there a way to parse a command prompt command to specific fields inside of a form such as the command ipconfig /all?

Here is a snippet of an XML file that I need to read with VB.NET[code]...
I am familiar with creating a new XmlDocument and using the Load method to read the file. I know how to get a collection of child nodes and loop through them to get elements and attributes. But in this case, I need to extract all of the data between the two "verse" tags (the starting one with the "sID" attribute and the ending one with the "eID" attribute), including the tags and the data in between as one continuous string. I can loop on the nodes, but I only get the "w" nodes and one final "#text" node for the period, but I don't know how to get the spaces and punctuation between the "w" tags.
I have a comma delimited text file with the U.S. States and their respective state bird listed in the following format.
