// Application Loader Events
//
// Note: these events are defined relative to AL_BASE_EVENT and use the
//       range AL_BASE_EVENT to AL_BASE_EVENT + 0x7F.  The application
//       loader internally uses events in the range AL_BASE_EVENT+0x80 to
//       AL_BASE_EVENT+0xFF, so events in this range must not be defined
//       as part of the API.

//
// ALS_LOAD_RESULT
//
// Overview:
//
//   This event informs a task of the result of an attempted load on a
//   remote machine.
//
// Parameters:
//
//   param_1 :      AL_LOAD_RESULT  reasonCode;
//   param_2 :      UINT            alPersonHandle;
//
//   reasonCode           : Result of attempt to load application
//
//   alPersonHandle       : Handle for the site that attempted the load
//                          (pass to ALS_GetPersonData() to get site name)
//
// Issued to:
//
//   Applications that have registered a function profile that has been
//   used by the Application Loader on a remote site.
//
// Circumstances when issued:
//
//   When the Application Loader on a remote site attempts to load an
//   application due to a new Function Profile object being added to a
//   call.
//
// Receivers response:
//
//   None
//
//



//
// AL_RETRY_NEW_CALL
//
// If AL fails to register with ObManControl on receipt of a CMS_NEW_CALL,
// it will in certain circumstances retry the registration after a short
// delay.  This is implemented by posting an AL_RETRY_NEW_CALL event back
// to itself.
//


//
// AL_INT_STARTSTOP_WB
//
// This starts/stops the old Whiteboard, which is now an MFC dll in CONF's
// process that creates/terminates a thread.  By having CONF itself start
// old WB through us, autolaunch and normal launch are synchronized.
//
// TEMP HACK:
// param1 == TRUE or FALSE (TRUE for new WB TEMP HACK!, FALSE for normal old WB)
// param2 == memory block (receiver must free) of file name to open
//
