I think I can not purge via DBX.

So what can I do with DBX?Is there a list of methods that I can use via DBX?

Hi,

You can only use the ActiveX interface.

But it can not find purgeall method via DBX

No you can't use PurgeAll.

To get all available properies and method for acadObj, do:

(vlax-dump-object acadObj T)
