Controlling CWEs and Notifications in Lync 2010 Contextual Conversations: Desktop Applications (Part 3 of 3)
Summary: This article describes how to add three registry entries in various combinations to control the display of the Conversation Window Extension (CWE) and the start link notification in a Microsoft Lync 2010 contextual conversation.

A desktop contextual application in this context is a Lync Windows Presentation Foundation (WPF) or Lync Model API application, or a C++ application that uses Office integration through the COM layer.
To register desktop applications, use the Path entry. Do not use the InternalURL and ExternalURL registry entries.
The examples in part 3 use simple WPF applications that have unique content in the Image and Label controls to visually distinguish the applications on the two computers. The Lync WPF application on the sending computer includes a StartInstantMessagingButton control that starts the conversation.
Desktop contextual applications do not use the CWE.
To include the start link notification
When registering the desktop application, include the Path entry as shown in figure 1.
Start the conversation. In figure 2, the conversation window opens and includes a start link notification.
On a computer that receives the message, click the invite. The conversation window opens and includes the start link notification. To open the contextual application, click the start link appearing in figure 3.
To start a conversation that excludes a start link notification
When registering the desktop application, do not include the Path entry as shown in figure 4.
Start the contextual conversation. In figure 5, the conversation window opens and it excludes a start link notification.
On a computer that receives the message, click the invite and the conversation window opens, as shown in figure 6. The start link is not displayed. Open the contextual application through another process.
Use the three registry entries that control the application path and the URL to control whether the CWE opens and whether the start link notification appears in the conversation window. The three registry entries:
Including these entries in different combinations when you register a contextual application determines whether the start link and CWE appear in a conversation.
