- Deleting the last element
- Miscellaneous
Elimina un elemento en una posición determinada: - de un array WLanguage unidimensional.
- de una propiedad array de un tipo avanzado (array de eventos de gglCalendar, etc.).
- de un array asociativo.
- de una lista WLanguage.
El tamaño del array se reduce automáticamente. Observaciones: - Esta función es equivalente a la función ArrayDelete.
  Esta función solo se puede utilizar con variables de tipo Array y Associative array.
MyArray is array of 2 strings
MyArray[1] = "WINDEV"
MyArray[2] = "WEBDEV"
// Delete the 1st element
Delete(MyArray, 1) // Deletes "WINDEV"
// Display the 1st element
Trace(MyArray[1]) // Displays "WEBDEV"
// Associative array Last Name - First Name
aaLastNameFirstName is associative array of strings
Insert(aaLastNameFirstName, "Smith", "Tommy")
Insert(aaLastNameFirstName, "Montgomery", "Julia")
Delete(aaLastNameFirstName, "Smith")
// Deletion during a browse
sLastName is string
sFirstName is string
FOR EACH ELEMENT sFirstName, sLastName OF aaLastNameFirstName
Trace(sFirstName + ":" + sLastName)
Delete(aaLastNameFirstName, CurrentElement)
END
Sintaxis
Eliminar un elemento de un array WLanguage o de una propiedad array de un tipo avanzado Ocultar los detalles
<Result> = Delete(<WLanguage array> , <Element index>)
<Result>: Integro Number of deleted elements (always corresponds to 1). <WLanguage array>: Array Name of the Array variable to use. This array must be a one-dimensional array. <Element index>: Integro - Index of the element to be deleted. A WLanguage error occurs if this parameter is greater than the number of array elements.
- The following constants can be used:
| | | CurrentElement | The current element is deleted. This constant is used to delete the current element during a FOR EACH browse. This constant is only available for associative arrays. | | FirstElement | The first array element is deleted. |
Eliminar un elemento de un array asociativo Ocultar los detalles
<Result> = Delete(<WLanguage array> , <Element key>)
<Result>: Integro Number of deleted elements:- 1 or 0 for the associative arrays without duplicates.
- 0 to N for the associative arrays with duplicates.
<WLanguage array>: Array asociativo Name of the Associative Array variable to use. <Element key>: Integro - Value of key corresponding to the element to delete.
- In an associative array without duplicates If the element exists, it is deleted; if the element does not exist, no operation is performed.
- In an associative array with duplicates: If the element exists, all the <Element key> elements are removed; if the element does not exist, no operation is performed.
- This parameter can also correspond to the CurrentElement constant. This syntax is used to delete the current element during a FOR EACH browse.
Eliminar un elemento de una variable de tipo List Ocultar los detalles
<Result> = Delete(<WLanguage list> , <Element index>)
<Result>: Integro Number of deleted elements (1 for the lists). <WLanguage list>: Lista Name of List variable to use. <Element index>: Constante de tipo Integer Index of the list where the element will be deleted. The following constants can be used:
| | | CurrentElement | The current element is deleted. For a list, this constant is available when browsing the list elements (during a FOR EACH browse). | | FirstElement | The first element found in the list is deleted. | | LastElement | The last element found in the list is deleted. |
Observaciones Deleting the last element If the last element is deleted, the array is resized to 0. The array is not freed: new additions can be made without reallocating the array. Miscellaneous This function cannot be used with the fixed arrays.
