Module Name:

    DataChannelMgrP.h

Abstract:

    Wizard-generated code for invoking data channel event sink functions.

    I added the "scriptDisp" field.  If it is non-NULL, then its default method
    will be called along with any registered interfaces.  This is to accomodate
    script clients that need to bind their event interfaces when the script
    engine initializes.  Our objects are dynamically retrieved by the client
    script or application post-init.
