问题:
Acad.lsp is reloading when -VBARUN command is used in the S::STARTUP function
to load a drawing. Is this known behavior and is there a way to stop it from
reloading?  The ACADLSPASDOC  variable is 0.

解答:
The reason that Acad.lsp is reloading, with a drawing opened by a procedure
in  Acad.dvb (called with -VBARUN in S:STARTUP), is that AutoCAD has not finished
initializing at the point in the S::STARTUP function where the command -VBARUN
is called.  As a workaround, the VBASTMT command allows you to call VBA functions
with arguments, from either the command line or a LISP expression.  In this
case, we can use (vla-sendcommand) in the (S::STARTUP) function, to call the
VBA "RunMacro" method.  This approach will not cause a reload of Acad.lsp.

  1. (defun-q mystartup ( )
  2.    (vl-load-com) ;load ActiveX objects
  3.    ;;replace this line: (command ".-vbarun" "MyModule.MySub")
  4.    ;;with the following:
  5.    (arxload "acadvba.arx") ;ensure Acad.dvb is loaded
  6.    (vla-sendcommand
  7.       (vla-get-activedocument (vlax-get-acad-object))
  8.       "vbastmt\n\ThisDrawing.Application.RunMacro \"MyModule.MySub\"\n"
  9.    )
  10. )


  11. (setq s::startup (append s::startup mystartup))
