ActiveXperts Twitter Toolkit Manual

1. Introduction

1.1. Introduction

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 can use the ActiveXperts Twitter toolkit.

The ActiveXperts Twitter Toolkit 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 client and browser applications
Authenticate users in only two API calls
Access all of the functions that are publicly available on the Twitter RESTfull interface
Proved an interface to send custom, OAuth signed, requests to the Twitter RESTfull interface

1.2. Architecture

The ActiveXperts Twitter Toolkit provides it's users with an easy to use front end on the Twitter REST API. By installing the Twitter Toolkit ActiveX component you will be able to access its interface from most programming languages and environments such as: C#, C++, VB.NET, Delphi, PHP, ASP, ASP.NET, Javascript, etc.. The Twitter Toolkit provides its own API as well as a way to automatically sign direct calls to the Twitter REST API. This ensures that the Twitter Toolkit will always support everything that is supported by Twitters own REST API as well as a straightforward way to access Twitters basic functions.

The core of ActiveXperts Twitter Toolkit is an ActiveX/COM component that comes in a 32-bit and a 64-bit version:

TwitterTk.dll, 'Twitter COM Component' for 32-bit platforms
TwitterTkx64.dll, 'Twitter COM Component' for 64-bit platforms

The ActiveXperts Twitter Toolkit can be distributed easily to any server and workstation in your network since only the file related to the target platform (32 or 64 bit) is required.

1.3. OAuth Authorization

Twitter relies on the OAuth (Open Authorization) standard for authorizing its users when trying to access information about protected users or API functions. OAuth is different from many authorization methods in that it allows users to authorize applications to use a resource on their behalf without handing out their credentials. Find more information on the OAuth getting started page.

To be able to post tweets or to look at a protected users time-line using the Twitter toolkit you will need the following:

Consumer token and secret. This identifies your application to Twitter.
Access token and secret. This identifies the user as well as the fact it granted access to your application.

Before your application can ask a user to grant access to their Twitter account it needs to have its own consumer token and consumer secret. You can get these by registering your application with twitter here.

With a consumer token and secret you can ask a user to grant access to your application. If the user grants access you will receive an access token as well as an access secret. With these you can act an behalf of the user as long as the user does not revoke your access through the Twitter web interface.

In addition the OAuth standard offers two use cases. A client use case for stand alone applications and a web use case for better integration into a web application. The Twitter toolkit provides support for both use cases.

With the Twitter Toolkit we aimed at greatly simplifying the OAuth process by only requiring two function calls which integrate both the web and client use cases. First call the RequestAuthorization method to request the authorization URL. Next call RequestAccessToken to request the actual access token and secret. Find examples in the Introduction of the How to Use section. Or look at our consumer and access key wizard

2. System Requirements

2.1. System Requirements

The Twitter Toolkit can be used by any of the following operating systems:

Windows XP, x86 (32-bit) and x64 (64-bit)
Windows 2003, x86 (32-bit) and x64 (64-bit)
Windows 2008, x86 (32-bit) and x64 (64-bit)
Windows Vista, x86 (32-bit) and x64 (64-bit)
Windows 7, x86 (32-bit) and x64 (64-bit)

NOTE: On 64 bits systems, you can run 32- and 64 bit programs. To integrate The Twitter Toolkit in a 64-bit (web) application of service, use the 64-bit TwitterTkX64.dll. To integrate The Twitter Toolkit in a 32-bit (web) application of service, use the 32-bit TwitterTk.dll.

2.2. Support Development Platforms

The Twitter Toolkit can be used by any of the following programming languages:

Visual Basic .NET
Visual C# .NET
Visual Basic 5.x or higher
Visual C++ 5.x or higher
Delphi 6.x or higher
ASP .NET
ASP classic
PHP
ColdFusion
VBScript
Javascript
HTML
Any other development platform that supports ActiveX/COM components

3. Installation

3.1. Installation

To install the components simply run the TwitterTK.EXE Setup program. The InstallShield wizard will guide you through the rest of the setup. The Setup program can perform the registration of the COM component for you. But it will also give you the opportunity to register the object yourself.

The Twitter Toolkit package consists of 3 components; any combination of components can be installed:

The Twitter Toolkit COM component
The Twitter Toolkit Help Files
The Twitter Toolkit Sample Files

The COM component, which is the interface to COM compliant applications, includes a 32 bit dll (TwitterTk.dll) and 64 bit dll (TwitterTkx64.dll)

4. How to use

4.1. Introduction

The following code snippets (VBScript) illustrate the use of the ActiveXperts Twitter Toolkit in various situations. Consumer token and secret as well as access token and secret are substituted by rows of dots ('.'). To use the samples obtain a consumer key with Twitter here.

The following sample shows how to Authorize on Twitter and send a Tweet. For more information about OAuth in the Twitter Toolkit click here. Try our consumer and access key wizard to create your own consumer key and access key.

Authorize and send a Tweet

4.4. Visual Basic

Twitter Toolkit can be used in Visual Basic 5.x or higher. In Visual Basic, go to the 'Project/References...' menu item and check the box next to Twitter Toolkit Type Library. Now, you can declare and create Twitter Toolkit objects.

Create new Twitter Toolkit objects using the 'CreateObject' function:

  Dim objTwitter As TwitterTKLib.Twitter                        ' Declaration
  Set objTwitter = CreateObject("ActiveXperts.Twitter")         ' Creation

  Dim objTweet As TwitterTKLib.Tweet                            ' Declaration
  Set objTweet = CreateObject( "ActiveXperts.Twitter.Tweet" )   ' Creation
  
  Dim objUser  As TwitterTKLib.User                             ' Declaration
  Set objUser = CreateObject( "ActiveXperts.Twitter.User")      ' Creation

4.5. Visual C++

The Twitter Toolkit can be used in Visual C++ projects. Include the *.h and *.c file provided by ActiveXperts to bind your code to the Twitter Toolkit component. These files are located in the Include directory of the Visual C++ samples directory. These are the files:

twittertk.h
twittertk_i.c

Declare and create new Twitter Toolkit objects like this:

  ITwitter *pTwitter;              
  CoCreateInstance(CLSID_Twitter, NULL, CLSCTX_INPROC_SERVER, IID_ITwitter, (void**) &Twitter ); 
    
  ITweet *pTweet;
  CoCreateInstance(CLSID_Tweet, NULL, CLSCTX_INPROC_SERVER, IID_ITweet, (void**) &pTweet );

  IUser *pUser;              
  CoCreateInstance(CLSID_User, NULL, CLSCTX_INPROC_SERVER, IID_IUser, (void**) &pUser );

4.6. ASP Classic

  <html>
  <body>
  Version:
  <script language="vbscript" runat="server">
    Set objTwitter = CreateObject( "ActiveXperts.Twitter" )
    Set objTweet = CreateObject( "ActiveXperts.Twitter.Tweet" )
    Set objUser = CreateObject( "ActiveXperts.Twitter.User" )
    Response.Write objTwitter.Version
  </script>
  </body>
  </html>

4.7. Delphi 7.x or higher

First, add a reference to the Twitter Toolkit objects:

Go to Project->Import Type Library

  objUser     := TUser.Create(Form1).DefaultInterface;      { Creation new instance of the object }

5. API Reference

5.1. Introduction

The ActiveXperts Twitter Toolkit API defines an interface to Twitters REST API. At one hand it provides an easy and intuitive interface which serves as a transparent abstraction over the Twitter API and on the other hand it provides a method to call Twitter API functions directly, while automatically signing the calls, which ensures compatibility with future extensions of the Twitter REST API.

OAuth authorization is completely integrated to the point where only two function call are needed to authenticate a user for either web or the client use-cases. This also enables you to have custom calls to the Twitter REST API automatically signed according to the given credentials.

Find more information about how to authorize on Twitter using the Twitter Toolkit in the Introduction of the How to use section. Try our consumer and access key wizard to create your own consumer key and access key.

  objTwitter.Tweet "Just (securely) Tweeting about the ActiveXperts Twitter Toolkit again."
  ...

Activate function

This function activates the Twitter Toolkit product. A valid registration code should be passed as parameter.

Parameters:

The registration key
Persistent - this optional Boolean variable (default: True) specifies whether you want to add the registration key to the registry. If you pass 'True', you need to call the 'Activate' function only once for that computer. If you pass 'False', you need to call 'Activate' each time you create the object on that computer. This can be useful for customers who own a Distribution License of the product but do not want to show the registration key to their customers (see also here).

Return value:

Always 0. Check LastError property to see if the function was completed successfully.

Example:

  Set objTwitter = CreateObject( "ActiveXperts.Twitter" )
            
  objTwitter.Activate "xxxxx-xxxxx-xxxxx", True
  ...

Clear function

This function resets all properties to their default values.

Parameters:

None

Return value:

Always 0.

  ...

GetErrorDescription function

GetErrorDescription provides the error description of a given error code.

Parameters:

The error code

Return value:

The error string.

Example:

  Set objTwitter = CreateObject( "ActiveXperts.Twitter" )
            
  objTwitter.Tweet "Just Tweeting about the ActiveXperts Twitter Toolkit again."
  WScript.Echo "Tweet result: " & objTwitter.LastError & ", " & _
    objTwitter.GetErrorDescription(objTwitter.LastError)

RequestAuthorization function

This is the first method to be called when requesting an access token. This function returns an URL which contains all of the information needed for Twitter to let the user authenticate the calling application.

When the user is redirected to this URL the user is asked for his/her name and password and when correctly identified can either grant or deny access for your application on his behalf.

If the user grants access the user if presented with either a verification code, if client authorization was chosen. Or the user will be redirected to a page in your web application if web authorization was chosen.

6. Error codes

6.1. Error codes

When a function is called, the result of the function is stored in the object's 'LastError' property. When 'LastError' is 0, it means that the last called function completed successfully; otherwise, an error occurred.

The value of the LastError tells you why the function failed. All error codes are listed on the ActiveXperts web site, here.

Alternatively, the 'GetErrorDescription' function can be used to find the error description for a given error code.

7. Support

7.1. Product samples

Samples for Visual Basic, Visual Basic .NET, Visual C++, Visual C# .NET, ASP and VBScript are included as part of the installation.

7.2. ActiveXperts support

Visit the ActiveXperts Support Site for a complete list of FAQ items at: http://www.activexperts.com/support

To contact support, please send an e-mail to: support@activexperts.com

8. Purchase and activation

8.1. Purchase

Please visit www.activexperts.com/sales to buy the product. Here, you can also find the latest prices. You can also contact us via email: sales@activexperts.com

8.2. Product Activation

After you purchase the product, you will receive a registration code. This code must be entered in the registry on your machine(s). There are three ways to accomplish this:

1. Automatic installation

The Twitter Toolkit automatic installation performs all necessary steps to install and register the component. It will ask for the registration code during installation and will enter the registration code in the registry.

2. 'Activate' function

You can use the Activate function.

Set objTwitter = CreateObject("ActiveXperts.Twitter ")
objTwitter.Activate XXXXX-XXXXX-XXXXX", True ' 'XXXXX-XXXXX-XXXXX' represents the registration code
                     ' Pass True to make the activation persistent, so you need to
                     ' call Activate only once. If you pass False, you need to call Activate
                     ' each time the product is started.

The Activate function of any of the objects writes the following entry to the registry, which will actually activate the product:

    Key: HKEY_LOCAL_MACHINE\Software\ActiveXperts\Twitter Toolkit\RegistrationKey  
    Type: REG_SZ  Value: XXXXX-XXXXX-XXXXX

where 'XXXXX-XXXXX-XXXXX' is the registration code issued to you.

3. Manually insert code in the registry

You can activate the product by editing the registry manually:

Start the registry editor (either REGEDT32.EXE or REGEDIT.EXE);
Open the 'HKEY_LOCAL_MACHINE\Software\ActiveXperts\Twitter Toolkit' key;
Add/modify the 'RegistrationKey' value: Type: REG_SZ, Value: XXXXX-XXXXX-XXXXX
