IMessengerConversationWnd::Contacts
This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.
Retrieves a read-only collection of contacts in the conversation window. Not scriptable.
Syntax
HRESULT Contacts(
[out,
retval] IDispatch** pContacts
);
Parameters
- pContacts
Address of a pointer to an IDispatch interface on a MessengerContacts object that contains the participants of that conversation, excluding the local user.
Return Value
Returns one of the following values. For managed code applications, these return values are received in the form of a COMException.
- S_OK
Success.
- RPC_X_NULL_REF_POINTER
pContacts is a null pointer.
- E_FAIL
The client is not signed in to the primary service at the time this method is called.
- S_FALSE
Cannot bring focus to the window.
Remarks
The contact collection returned by this property includes all Office Communicator users who are participating in the current IM conversation. This list includes the local client user. Each contact object in the collection gives you access to the properties and methods of the IMessengerContact interface. Office Communicator Automation API does not prohibit you from adding a contact that is already in the conference. Before adding a new contact, you should iterate on the collection and verify the contact is not already in the conference.
Example
The example code instantiates and fills a contact collection object, contactList as an IMessengerContacts interface object. The Contacts property is queried from the imWindow object and the returned contact collection is iterated over to produce a list of contact friendly names for display on the application console window.
try
{
StringBuilder sb = new StringBuilder();
IMessengerContacts contactList =
(IMessengerContacts)imWindow.Contacts;
foreach (IMessengerContact contactItem in contactList)
{
sb.Append(contactItem.FriendlyName);
sb.Append(Environment.NewLine);
}
Console.WriteLine(sb.ToString());
}
catch (COMException CE)
{
Console.WriteLine("COM Exception " + CE.ErrorCode.ToString());
}
