Events inside events

How do I define an event procedure to fire only after another one is fired,
and then shut itself off after it done?

I'm trying to come up with the VBA equivalent to the S::Startup function. I
don't have access to the Acad.lsp file. I found a post here about the
endopen event and learned that it needs to go in a class module. I would
like to load a lisp function after it has been opened. but I need to wait
till the command prompt is active again.

From inside the App_EndOpen event what other event would you wait for, or
How would you know if the command prompt is active?

Thanks

Sorry I can't offer any help Matthew. However, i'm curious as to the timing of this. Why is this lisp so important to be loaded with such precise timing?

 

Timing had nothing to do with it, it was more of a load order. I was trying
to use the VLAX class to load a lisp function but that will not work till
after the command prompt is active again. the EndOpen event fires before I
can Use the VLAX class from Frank Q.
I get an error message:

Run-time error '2000':
no applicable method for (lisplet-set-current nil)

from this line
VLObj.EvalLispExpression("(Load ""AC_UTILS.LSP"")")

or If I do a sendkeys ("(Load ""AC_UTILS.LSP"")") I get a "AutoCAD is Busy"
alert message.
I have to wait for something else but I don't know what. I have resorted
setting a variable in the EndOpen event then checking it's status in the
other event.


Thanks
