vlax-safearray-get-l-bound
 
 
 

Returns the lower boundary (starting index) of a dimension of an array

(vlax-safearray-get-l-bound var dim)

Arguments

var

A variable whose data type is a safearray.

dim

A dimension of the array. The first dimension is dimension 1.

Return Values

An integer representing the lower boundary (starting index) of the dimension. If var is not an array, or dim is invalid (for example, 0, or a number greater than the number of dimensions in the array), an error results.

Examples

The following examples evaluate a safearray defined as follows:

(vlax-make-safearray vlax-vbString '(1 . 2) '(0 . 1) ))

Get the starting index value of the array's first dimension:

_$ (vlax-safearray-get-l-bound
tmatrix 1)
1

The first dimension starts with index 1.

Get the starting index value of the second dimension of the array:

_$ (vlax-safearray-get-l-bound
tmatrix 2)
0

The second dimension starts with index 0.
