I don't know APIs? but i heard of Daniweb API. what it is ?
Now i am playing with basic controls of vb.net but i hope after getting about API i'll be able to guess what kind of application i create in vb.net using Daniweb API?
So , i won't overload this thread by asking How to use APIs in vb.net. first i will understand what daniweb api is ? then create new thread for how to use it in vb.net so i can play with it.
thanks.

You can write a native chat application, for example.
As dani suggested that i have to send http request if i use daniweb api?
so , anybody here would tell how to send http request in vb.net ?
Found this thread after replying to your PM ;)
Basically, you can retrieve the (cached, without logging in) solved threads for a forum by building an URL and using that to retrieve data from the API. I have PHP classes on GitHub that do this. Basically, it's the same in VB.NET. You just need to use a different component for getting data, possibly HttpWebRequest.
Building the URL is as follows (see the API documentation for Fetch Articles)
http://www.daniweb.com/api/forums/58/articles?filter=solved
It tells you to fetch the VB.NET (ID=58) solved (filter) articles.
MSDN article on using WebRequest is here.
What's returned is JSON, so you need something like JSON.NET to parse it.
Hope this helps.
I just finished rewriting the API documentation. There are two additional tutorials about OAuth.
i tried following :
' Create a request for the URL.
Dim request As WebRequest = WebRequest.Create("http://www.daniweb.com/api/forums/58/articles?filter=solved")
' If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials
' Get the response.
Dim response As WebResponse = request.GetResponse()
' Display the status.
Console.WriteLine(CType(response, HttpWebResponse).StatusDescription)
' Get the stream containing content returned by the server.
Dim dataStream As Stream = response.GetResponseStream()
' Open the stream using a StreamReader for easy access.
Dim reader As New StreamReader(dataStream)
' Read the content.
Dim responseFromServer As String = reader.ReadToEnd()
' Display the content.
RichTextBox1.Text = (responseFromServer)
' Clean up the streams and the response.
reader.Close()
response.Close()
and i get the the result in the following format and how can i customize it

How can i customize it.
Now how to convert JSON result into readable format.
i've heard of DeserializeObject() But don't know how to use it.
and also ignore line 8 in the above post.
I already pointed to JSON.NET to read/convert the output.
It seems he is still very confused: http://www.daniweb.com/software-development/vbnet/threads/469909/deserialize-json-result-in-vb.net
Perhaps a code example to help him out?
