Remarks

CreateComposeForm is called by Messaging to create the form that is used to create messages for your custom form. The form creates a window as a child of the Messaging window. CreateComposeForm returns a handle to the window it has created and a handle to an IMessageFormEx interface. When Messaging calls this method, it passes an IMessageFormHostEx pointer that allows the custom form to communicate with the Messaging application.
