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.

Information is at http://www.daniweb.com/api/home

Essentially you can tap into our entire database. With all of the raw content from our database, the sky is the limit when it comes to what you can create. You can build lots of functionality that isn't currently built into the site.

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
