How to use ActiveXperts Twitter Toolkit with Microsoft Visual C# .NET

Twitter is a popular social networking service that enables its users to send and read messages called Tweets. Tweets are text-based posts of up to 140 characters. They are displayed on the author's profile page.

Twitter users can send and receive tweets through the Twitter website or through compatible applications. Applications that want to send or receive Tweets have the option of using Twitters HTTP based RESTfull API. The ActiveXperts Twitter Toolkit provides a user friendly wrapper around Twitters own HTTP based API.

The ActiveXperts Twitter API supports the following:

  • Post your Tweets on Twitter using your own software
  • Easy browsing through your own Tweets or the Tweets on any other time-line
  • Easy browsing through friends and followers
  • Integrated OAuth (Open Authorization) supports both both Client and Web use cases
  • Authenticate users in only two steps
  • Access all of the functions that are publicly available on the Twittter HTTP interface
  • Proved an interface to send custom, OAuth signed, requests to the Twitter HTTP interface

This tutorial describes how the Twitter Toolkit can be integrated in Microsoft Visual C# .NET projects.

Step 3: Refer to the Twitter Toolkit Library and create the objects

Now that a new project has been created, you must add a reference to the ActiveXperts Twitter Toolkit in the project to be able to use the Twitter Toolkit object. To do so, choose 'Add Reference...' from the 'Project' menu. In the 'Add Reference' dialog that pops up, select the 'COM' tab and select the 'Twitter Toolkit Type Library' as shown in the following picture:

Click 'OK' to close the 'Add Reference' dialog.

On top of your code, type the following line to use the Twitter Toolkit namespace: 

using twitter-componentLib;

In your Main function, declare and create the following object: 

public Twitter m_objTwitter;
	
m_objTwitter = new Twitter();

Step 4: Tweet a message

The following code shows how to tweet a message using CSharp 

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using twitter-componentLib;

namespace Tweet
{
  class Tweet
  {
    static void Main(string[] args)
    {
      string strConsumerKeyFile, strAccessKeyFile;
      Twitter objTwitter = new Twitter(); // Create instance of COM Object

      Console.WriteLine("Twitter Toolkit {0}", objTwitter.Build );

      // To enable logging,assign a valid log file to the LogFile property
      // objTwitter.LogFile = "C:\\TwitterToolkit.log";

      objTwitter.LoadConsumerKey("C:\\Consumer.key");
      Console.WriteLine("LoadConsumerKey, result: {0})", objTwitter.LastError);
      if( objTwitter.LastError != 0 )
        return;

      objTwitter.LoadAccessKey("C:\\Access.key");
      Console.WriteLine("LoadAccessKey, result: {0}", objTwitter.LastError );   
      if (objTwitter.LastError != 0)
        return;

      objTwitter.Tweet("I'm tweeting using ActiveXperts Twitter Toolkit.");
      Console.WriteLine("Tweet, result: {0}", objTwitter.LastError );
    }
  }
}
