Extracting block properties using vlax function

[AbdRF]

Hello all,

I need some help with extracting the block properties using vlax function.
After doing some research I found this, for eg: to extract the block insertion point -

(vlax-get (vlax-ename->vla-object (car (entsel "\nSelect object: "))) 'InsertionPoint)

But if I tried to extract the block scale value using the same logic like this ,it is giving error

(vlax-get (vlax-ename->vla-object (car (entsel "\nSelect object: "))) 'Scale)

Here is the error which I got 
Select object: ; error: ActiveX Server returned the error: unknown name: "SCALE"
 

So can somebody help me out in extracting the block scale value using the vlax function?
Also, what is the difference between "vlax-get" and "vlax-get-property" ?

Thanks

If using VL recommend using dumpit.lsp so can see properties there are though different methods available to get the same answer as posted by rlx

Thanks @rlx. With this, I am able to extract the scale value.
