Reports and Queries

Modified element

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


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