In french: <Source>.DésactiveFiltre

Not available with this kind of connection

Temporarily disables the filter on a data file (view or query). This filter was created by <Source>.Filter. <Source>.DeactivateFilter has no effect if no filter was declared.

Example

// Déclaration du filtre : sélection des clients
// qui ont entre 20 et 60 ans
Client.Filtre(Age_Client, 20, 60)
...
Client.DésactiveFiltre() // Filtre désactivé
...
// Parcours du fichier de données avec filtre sur l'âge
// Traitement des clients qui ont entre 20 et 60 ans
// (procédure TraiteClient2060)
Client.ActiveFiltre()
Client.LitPremier(Age_Client)
WHILE Client.Trouve() = True
	TraiteClient2060()
	Client.LitSuivant(Age_Client)
END

Syntax

<Result> = <Source>.DeactivateFilter()

<Result>: Boolean

True if the filter is disabled,
False if an error occurred (data file or item not found).

<Source>: Type corresponding to the specified source

The filter is enabled once it has been declared (<Source>.Filter). A filter disabled by <Source>.DeactivateFilter can be re-enabled by <Source>.ActivateFilter.

Note: When calling function <Source>.Close, the filter activated by function HFilter function is automatically deleted.

Number of possible active filters

A single filter can be enabled at a time for a specific data file.
