How to use Safearray...

[Lt Dan's legs]

When searching for safearray I found different ones. I'm confused as to how to use. Can anyone fill me in?

You might try reading the Developer Documentation, via the Apropos menu search for "safearray."

 

Snippet:

vlax-make-safearray

 

Creates a safearray

 

(vlax-make-safearray type '(l-bound . u-bound)['(l-bound . u-bound)...)]

 

A maximum of 16 dimensions can be defined for an array. The elements in the array are initialized as follows:

 

Numbers

0

 

Strings

Zero-length string.

 

Booleans

:vlax-false

 

Object

nil

 

Variant

Uninitialized (vlax-vbEmpty)

 

Arguments

 

type

The type of safearray. Specify one of the following constants:

vlax-vbInteger (2) Integer

vlax-vbLong (3) Long integer

vlax-vbSingle (4) Single-precision floating-point number

vlax-vbDouble (5) Double-precision floating-point number

vlax-vbString (8 ) String

vlax-vbObject (9) Object

vlax-vbBoolean (11) Boolean

vlax-vbVariant (12) Variant

The integer shown in parentheses indicates the value to which the constant evaluates. It is recommended that you specify the constant in your argument, not the integer value, in case the value changes in later releases of AutoCAD.

 

'(l-bound . u-bound)

Lower and upper index boundaries of a dimension.

 

Return Values

The safearray created.

 

Hope this helps!
