Microsoft Chat Server Development Guide

Create a new "ActiveX DLL" project

  1. Select ActiveX DLL from New Project dialog box.
  2. Set project properties:
    Select "Remote Server Files" on Component tab (Visual Basic Enterprise Edition only).
    Select "Unattended Execution" on General tab.
  3. Add a reference to "Microsoft Exchange Chat Server Extensibility 1.0 Library."
  4. Save your project with a new name.

Note: Whenever authoring extensions in Visual Basic, enabling Unattended Execution (on the project's General property page) automatically disables any calls that will cause user interface to be displayed.
