Syntax
<Result> = ListInsert(<List Box control> , <Element> [, <Image> [, <Element subscript>]])
<Result>: Boolean - True if the element was inserted,
- False otherwise.
<List Box control>: Control name Name of memory List Box or memory Combo Box control to use. If this parameter corresponds to an empty string (""), the element is inserted in the List Box or Combo Box control to which the current process belongs.
<Element>: Character string (with quotes) Element that must be inserted into the specified memory List Box (or Combo Box) control. This parameter can contain:- Carriage Return characters (CR) to add several rows. In this case:
- if <Element subscript> is not specified, the elements are actually added.
- If <Element subscript> is specified, only the first element will be added.
- tabs (TAB) to obtain a multi-element List Box control (see Notes).
<Image>: Optional character string (with quotes) Name and path of image that will be added into a ListView control. This parameter is taken into account for ListView controls displayed in ListView mode only. If this parameter is not specified, the default image (defined in the "Details" tab in the description window of control) will be used.
<Element subscript>: Optional integer Subscript of element to insert.If this parameter: - is not specified, the element is inserted:
- before the current element in a single-selection List Box control. If there is no current element, the element is inserted at the end of the memory List Box (or Combo Box) control.
- at the end of the List Box (or Combo Box) control in a multiselection List Box control.
- is greater than the number of elements found in the List Box (or Combo Box) control, the element is inserted at the end of the memory List Box (or Combo Box) control. The number of elements found in a List Box (or Combo Box) control is returned by ListCount.
- is equal to 0, the element is added at the beginning of memory List Box (or Combo Box) control.
Remarks List Box controls containing more than 10 000 elements The maximum number of elements found in a List Box control is limited by the available memory (theoretical maximum: 2 billion rows). Nevertheless, filling a List Box control with an important number of elements (more than 10 000) affects the performances. To add a large number of elements to a List Box control, we recommend you use a browsing List Box control (that is a List Box control directly linked to a HFSQL data file). Miscellaneous - To insert an element into a Table control, use TableInsert.
- ListInsert can be used on a "Combo box" column found in a Table control .
