Topic: MAP Projects object - Starting off with VLisp in MAP

[sparky]

Code: [Select]

(setq Amap (vla-getInterfaceObject (setq Acadobj (vlax-get-acad-object)) "AutoCADMap.Application")
      MapProjsColl (vla-get-Projects Amap)
      )

That's me trying to get a reference to the Projects Collection in MAP.  Unfortuneatly I get an error at the second setq assignment "Failure: no function defintion: VLA-GET-PROJECTS".

Have I missed something about the structure of the MAP add on Object to 2K2?  The VLisp editor doesn't highlight the method/property call to the Amap obj (which does actually produce a valid AcadMap object), which I guessed meant the setq wouldn't work!?  

The Inquiry window on the Amap obj lists the four sub collections/Properties, but the normal vla-get call doean't retrieve the refernece!!

The Map library is not included in the standard types. This works:
(vlax-get Amap 'Projects)
You could also do this:

Code: [Select]


(vlax-import-type-library
   :tlb-filename   "AMVbApi.tlb"
   :methods-prefix     "map-"
   :properties-prefix  "map-"
   :constants-prefix   "vbmap-"
  ) ;

(setq MapProjsColl (map-get-Projects Amap))

Thanks...gave your tips a tryout and of course they work.  There were alot of map- methods and properties listed in the Apropo Window, so all was successful.  I can of course just invoke a Amap method using the vlax-invoke-method funtion, No?

At least I can spend some time now taking a look at the Map objects on offer and let them digest over a period.

Thanks for the lesson!
