Getting a Contact in C#

After a Communicator object (implementing the IMessenger and other interfaces) is created, you can call methods and properties of the interfaces implemented by the object. The following C# code shows an attempt to retrieve a specified contact listed in the connected Communicator.

CommunicatorAPI.Messenger communicator = new CommunicatorAPI.Messenger();

public IMessengerContact GetContact(string signinName)
{
    return communicator.GetContact(signinName, communicator.MyServiceId) as IMessengerContact;
}

Getting a Contact in C/C++

Retrieving a contact in C/C++ is more involved than in C#. The following C/C++ code shows an attempt to retrieve a specified contact that is listed in the connected Communicator.

IMessenger m_pIMessenger = ...;

IMessengerContact* GetContact(BSTR bstrSigninName)
{
      // Get the ID of the service behind the connected Communicator.
      // Property invocation.
      BSTR bstrServiceId;
      hr = m_pIMessenger->get_MyServiceId(&bstrServiceId);
      if (FAILED(hr))
         return NULL;

      // Get the named contact: method invocation
      IMessengerContact* pIMessengerContact;
      hr = m_pIMessenger->GetContact(bstrSigninName, bstrServiceId, 
                                     (IDispatch**)&pIMessengerContact);
      if (FAILED(hr))
         return NULL;

      return pIMessengerContact;
}

Getting a Contact in JavaScript

var comm = new ActiveXObject("Communicator.UIAutomation");
var contact = GetContact("jaya@contoso.com");

function GetContact(signinUri)
{
   var c = comm.GetContact(signinUri, comm.MyServiceId);
   return c;
   
}
