vla Functions

How do I know which parameters need to be put in expressions visual lisp?

For example, I took the properties and methods available:

# (setq vgad (vla-get-ActiveDocument (vlax-get-acad-object)))

(vlax-dump-object vgad T) #

Methods available to find:

...........

, Open (2)

, PurgeAll ()

, Regen (1)

, Save ()

, SaveAs (3)

...........

where what is written between parentheses (), is the number of parameters required for setting:

(vla-open 1? 2? 3?)

or

(vla-save?)

Where do I find what to use?

A good start here from Lee .

Thank you very much.

It is difficult to work this way, but if that is the only way ...

Thank you very much again.

Don't worry, after some practice you soon learn the parameters required by each method and, for commonly used methods, seldom need to reference the documentation.

Such documentation found for lisp, not only for vba ?

No ActiveX Documentation was ever released specifically for Visual LISP, only VBA; though the number of parameters, their order and data type all translate directly for use with Visual LISP. Also, in the 2013 ActiveX Documentation (linked above) there are Visual LISP examples alongside the VB examples.

I think this is the key

That is the AutoCAD Object Model, yes.

2013 ActiveX Documentation

I am unsure if this has been updated for 2013 or not, but I have found this site to be invaluable: http://entercad.ru/acadauto.en/

It is very good because it related directly to the point.
