I've created a page that makes several calls to different rss feeds based on the keywords I pass to the page. The problem is that each call takes .5 - 2 seconds to get a response and display the results. If I multiply the number of keywords by the time I end up with a very slow loading page. Is there a way to execute all of the calls at one time?
View 3 RepliesI have a CRM application that I would like to programatically post new records and updates to, based on values in other tables getting inserted or updated. Problem is because of how this CRM app was designed I cannot use straight SQL insert/update SQL commands. This is because the database has some proprietary account#/record ID generation algorithm, and also writes to a log table using some pretty cryptic looking values.
The only way to ensure the integrity of the data is to use a the COM based API they provide. How can I send calls to this API from SQL Server code, I'm guessing a CLR user defined function? Can anyone point me to such tutorial on the web?
The updates I am making MUST be in real time, that is why I need to use a trigger that calls this app's API.

I'm making an app using wpf and vb.net in vb2010 express and having a problem. I have a timer that execute a backgroundworker every minute:
Private Sub timer_Tick() Handles timer.Tick
If Not bworker.IsBusy Then
bworker.RunWorkerAsync()
End If
End Sub
The backgroundworker is working with xmlelement and xmldataprovider:
Private Sub bworker_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles bworker.DoWork
Dim source As XmlDataProvider = Application.Current.Resources("r1")
Dim sometext As String = "something"
Dim elemento As XmlElement = source.Document.CreateElement("elemento")
elemento.InnerText = sometext
e.Result = elemento
End Sub
Then I'm using e.Result on RunWorkerComplete to add the XmlElement to source. It works perfect the first time I execute the backgroundworker, but when the timer calls it the second time it throws a InvalidOperationException in the line "elemento.InnerText = sometext" why is that and how can I solve it?
What the Win32 API is? I have looked around but no where really outlines what it is. Is it basically a set of procedures, outlined by Microsoft for programmers in order to get services from the operating system? In essence is it the equivalent to making system calls abd and library calls in UNIX? And yes I now Windows makes library calls too.
View 2 RepliesI 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.

View 14 RepliesI 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

Dim xmlreq As MSXML2.XMLHTTP
Dim xmldoc As MSXML2.DOMDocument

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)

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

[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 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.
