Stored procedures
Deletes all elements:
  • from a one-dimensional or two-dimensional WLanguage array.
  • from an associative array.
  • from an advanced array property (array of gglCalendar events, ...).
  • from a WLanguage queue.
  • from a WLanguage stack.
  • from a WLanguage list.
Notes:
Example
MyArray is array of 2 strings
MyArray[1] = "WINDEV"
MyArray[2] = "WEBDEV"
// Delete all the elements
DeleteAll(MyArray)
Syntax
DeleteAll(<WLanguage variable>)
<WLanguage variable>: Array, Queue, Stack or List
Name of variable to use. This variable can be:
  • an Array. This array must be a one-dimensional array or a two-dimensional array.
  • a List.
  • a Stack.
  • a Queue.
Remarks

Deleting elements

  • One-dimensional array: the array is resized to 0. The array has not been deleted: new additions can be performed without re-creating the array.
  • Two-dimensional array: only the array rows are deleted. The columns are kept. Therefore, ArrayAddLine can be used after ArrayDeleteAll.
  • Associative array: all array elements are deleted.
  • Queue: all queue elements are deleted.
  • Stack: all stack elements are deleted.
  • List: all list elements are deleted.
Note: To reinitialize (reset to 0 or to empty string "") the array elements without resizing the array, use VariableReset.

Miscellaneous

This function cannot be used with the fixed arrays.
