acad_<true>colordlg compilation error

While packaging .lsp into .vlx in VLISP, the function calls of acad_colordlg(2002) and acad_reuecolordlg(2004) will be regarded as "null function" while executing the compiled VLX file, is there anyone know the reason and the solution?

 

Somewhere near the beginning of your primary source code you need to add those
function names to whatever else you need to import into your separate-namespace
VLX...
(foreach item '(ACAD_COLORDLG ACAD_STRLSORT INITDIA ACAD-POP-DBMOD
ACAD-PUSH-DBMOD STARTAPP <etc><etc>)
(vl-arx-import item)
)

Or, looking at it again for the first time in a long time...
(mapcar 'vl-arx-import '(ACAD_COLORDLG ACAD_STRLSORT INITDIA ACAD-POP-DBMOD
ACAD-PUSH-DBMOD STARTAPP))

acad_colordlg(2002) and acad_reuecolordlg(2004) will be regarded as "null
function" while executing the compiled VLX file, is there anyone know the reason
and the solution?

 

Thanks John for ur reply and i have fixed this problem

btw, what is the function of acad-pop-dbmod & acad-push-dbmod do?

 

acad-push-dbmod saves the current value of the DBMOD variable and suspends any
record of its change. acad-pop-dbmod restores the previous DBMOD value and
reenables its recording. A typical example of its use would be in your
acaddoc.lsp file where you might want to force the setting of certain drawing
variables without causing AutoCAD to retain any record of the drawings's
modification. The benefit is that the user might just want to see the drawing
or may have opened the wrong one, so unless he zooms/pans he can exit the
drawing without being asked to save changes, which is OK 'cause if he doesn't,
his variables can be fixed the next time it's opened.
