How to get properies and methods

Hello everyone .

I wonder how to get the properties of Layers, Layouts , Dimension Style and document etc .... ........

which are not being available to be selected by the use of function *vlax-dump-object* or any other function .

My intention is to get the properties and methods that are available for such a things.

Thanks a lot .

I'm kind of surprised that you even posed this question.

In any event...

This works for any valid VLA-OBJECT:

(defun DUMP (arg)
 (if (= 'VLA-OBJECT (type arg))
   (progn
      (textpage)
      (vlax-dump-object arg T))
   (prompt "\n** Invalid argument ** "))
 (princ))

However, here's are some examples of Layer specific DUMP routines from my toolbox:

(defun c:DUMPLAY  (/ layerName)
 (if (and (setq layerName (getstring "\nEnter layer name: "))
          (tblsearch "layer" layerName))
   (DUMPLAY layerName)
   (prompt "\n** Layer does not exist ** "))
 (princ))

(defun DUMPLAY  (layerName)
 (if (tblsearch "layer" layerName)
   (progn
     (textpage)
     (vlax-dump-object
       (vla-item (vla-get-layers
                   (vla-get-activedocument (vlax-get-acad-object)))
                 layerName)
       T))
   (prompt "\n** Layer does not exist ** "))
 (princ))

As Renderman correctly states, vlax-dump-object will work with any VLA-Object, whether such VLA-Object is part of the AutoCAD Object Model or otherwise.

For investigating objects within the hierarchy of the AutoCAD Object Model, I sometimes find it easier to use the Object Model flowchart in the ActiveX Developer Reference.

To access this, in the VLIDE Help Documentation, navigate to:

ActiveX and VBA Reference » Object Model

From here you can click on any object listed on the Object Model flowchart to see the properties/methods pertaining to that object, and furthermore you can quickly navigate to the documentation for each property/method.

Lee - You'd laugh, I've even gone into VBAIDE / Visual Studio to peruse the Object Viewer if I couldn't find what I was looking for. LoL

Thanks for the codes , they are very helpful .

ًWhy you are surprised dear Renderman ?

Thanks a lot .

Well, the VS Object Browser would probably be best for objects outside of the AutoCAD Object Model, so you're not going too far wrong

To access this, in the VLIDE Help Documentation, navigate to:

 

ActiveX and VBA Reference » Object Model

That's what I knew but did not know how to get Vla-object of it to extract its Props and Methods as well .

And what about dims and groups and viewports etc......

Thanks

Click on the item on the chart.

And what about dims and groups and viewports etc......

Every object in the model is listed.

If I'm totally off topic then I apologize. But I've had a similar "problem" previously. Tim Willey put me onto the TblInf32.DLL file. You'll need to load it through the vlax-import-type-library function and then you can see what's in it by downloading this help file: http://support.microsoft.com/kb/q224331/

That way you're able to get all the properties / methods into a list so you can place them (say) in a dialog box. That's actually what the Object Browser in VBA itself uses.

Running with that theme, this is a very interesting investigation into the Properties and Methods of the tool used to expose the Properties and Methods of other objects (TlbInf32.dll). As Michael states in that thread, it does have a sense of beauty in recursiveness of the statement.
