Reactor on File Opened !?

The following code should fire alerts at file Open, Save, Close. Save and Close works ok, but beginOpen EndOpen doesn't do anything. Is there any Reactor that works at file open? I have Autocad 2008.

                         (:vlr-beginClose . beginCloseCallback)
                         (:vlr-beginDwgOpen . beginOpenCallback)
                         (:vlr-endDwgOpen . endOpenCallback)
                         (:vlr-beginSave . beginSaveCallback)
                         (:vlr-saveComplete . saveCompleteCallback)
                       )

make it persistent reactor and make sure callback function is loaded at startapp but when transferring to other pc you'll have to load the callback function first for it to work.

Wizman, just a quick one - what is the difference between a persistent and transient reactor?

persistent reactors remain in the drawing. a reactor object can be persistent by function (vlr-pers reactor-object). Once persistent the reactor automatically loads itself as it is embedded in the reactor persistent dictionary. so no need for loading it again.

transient reactors are the normal default type of reactor which are not anymore functional once drawiing is closed.

but the callback functions (the lisp to run on an event) are not loading automatically unless loaded in the startup suite or acaddoc.lsp. I havent seen one callback function that is functional already without the use of starting in starup or (load) function. But may be through xdata, ldata, xrecord or registry to embed the callback. but still a reading function is still missing. but maybe call back function can also be saved and loaded the same way as how the reactor itself was saved in the dict. Maybe someone can give the missing link.

Thanks Wizman for the clarification - intriguing stuff
