Ejemplo
// Find the element "Moore" in the List Box control "LIST_CustomerList"
ResSeek = ListSeek(LIST_CustomerList, "Moore")
WINDEVWEBDEV - Código ServidorWEBDEV - Código NavegadorReportes y ConsultasAndroidWindows MobileUniversal Windows 10 AppJavaAjaxCódigo de Usuario (UMC)
// Find the element "Moore" in the browsing List Box control "LIST_CustomerList"
// Exact-match search from element 5
ResFind = ListSeek(LIST_CustomerList, "Moore", True, 5)
Sintaxis
<Result> = ListSeek(<List Box control> , <Sought element> [, <Type of search> [, <Start of search>]])
<Result>: Integer
  • Subscript of element found.
  • -1 if no element corresponds to the search.
The element found is not selected. To select the element found, use ListSelectPlus.
WINDEV In a browsing List Box control, the element found is displayed if it is not visible.
<List Box control>: Control name
Name of List Box (or Combo Box) control to use.
If this parameter corresponds to an empty string (""), the element is sought in the control to which the current process belongs.
WEBDEV - Código Navegador The name of List Box or Combo Box control to use must necessarily be specified.
<Sought element>: Character string (with quotes)
Element to find in the specified List Box (or Combo Box) control.
<Type of search>: Optional boolean
  • True (default value) for an exact-match search,
  • False for a generic search.
PHP This parameter is not available. An exact-match search is performed by default.
<Start of search>: Optional integer
Subscript from which the search will start in the List Box or Combo Box control.
If this parameter is not specified, the search is performed in the entire control. This parameter is ignored for the memory List Boxes.
PHP This parameter is not available. The search is performed in the entire control by default.
Observaciones

Type of search

  • Exact-match search:
    The elements whose value is strictly equal to <Sought element> are returned by ListSeek. For example:
    // Return all the customers named "Doe" found in "LIST_Name"
    ListSeek(LIST_Name, "Doe")
  • Generic search:
    The elements starting with <Sought element> are returned by ListSeek. For example:
    // Return all customers whose name starts with "SMI"
    ListSeek(LIST_Name, "SMI", False)

"Start of search" parameter

The <Start of search> parameter is used to find all the occurrences of a string in a List Box or Combo Box control.
For example, to count the number of names starting with "SMI" in the "LIST_CustomerList" control:
Subscript is int
Cnt is int = 0
// Position on the first corresponding element
Subscript = ListSeek(LIST_CustomerList, "SMI", False)
WHILE Subscript <> -1
Cnt++
// Find the next name starting with "SMI"
Subscript = ListSeek(LIST_CustomerList, "SMI", False, Subscript + 1)

Uppercase/Lowercase characters

  • If the control is a memory List Box control, the search ignores the uppercase and lowercase characters.
  • If the control is a browsing List Box control, the search performed on the "Key" items takes into account the "Search options" defined in the data model editor ("General" tab of item description).
PHP The search is case sensitive.
PHP The browsing List controls are not available.

  • If gLinkActivate(Control, True) (by default): ListSeek performs the search on the "search item" declared in the "Content" tab of control description.
  • If gLinkActivate(Control, False): ListSeek performs the search on the "displayed item" declared in the "Content" tab of control description.
Case 2: The List Box or Combo Box control is filled by a data file ("Loaded in memory" option):
ListSeek performs the search on the "displayed item" declared in the "Content" tab of control description.
