Deletes the specified element(s) from the specified 1D or 2D array
#include <Array.au3>
_ArrayDelete ( ByRef $aArray, $vRange )
| $aArray | Array to modify |
| $vRange | Element(s) to delete - either a single index, a range string or a 1D array with a count in the [0] element (see example for details) |
| Success: | the new size of the array (see remarks) |
| Failure: | -1 and sets the @error flag to non-zero. |
| @error: | 1 - $aArray is not an array 2 - $aArray is not a 1D or 2D array 3 - $vRange is not a valid range string 4 - $vRange is not a 1D array or has only 1 element 5 - $vRange content is outside array bounds |
$vRange can be a string containing the rows which are to be deleted. It can be a single number or a range denoted by the first and last lines separated by a hyphen (-) - multiple items are separated by a semi-colon (;).
$vRange can also be a 1D array listing all rows to be deleted with the count in the [0] element].
In either case, the rows need not be in ascending order and can be duplicated.
The function does NOT update any count element within the array, but the return value of the function (if successful) gives the new highest row index of the array.
