<Image>: Optional character string (with quotes)

Universal Windows 10 App This parameter is not available.
<Element subscript>: Optional integer
Subscript of element to modify.

  • is not specified or if it is set to -1, the current element is modified. <List Box>.Modify has no effect if there is no current element.
  • is equal to 0, the first element is modified.
  • is greater than the number of elements found in the List Box (or Combo Box) control, a WLanguage error occurs. The number of elements found in a List Box (or Combo Box) control is returned by <List Box>.Count.
Remarks

WINDEVJavaUser code (UMC)

Modified element

When modifying an element containing an invisible value (specified by gLink), gLink must be re-used. Otherwise, this invisible value will be lost during the modification.
For example:
  • adding "MyElement":
    COMBO_MyCombo.Add("MyElement" + gLink("1"))
  • modifying "MyElement":
    COMBO_MyCombo.Modify("MyNewElement" + gLink("1"))

Miscellaneous

  • To modify an element in a Table control, use <Table>.Modify.
  • <List Box>.Modify can be used on a "Combo Box" table column.
