Not available with this kind of connection

Cancels the current search criterion. The browse of the data file can continue from the current record, without using any search criterion. The browsed records will not necessarily correspond to the search condition.

Note The current Record has been selected using the search functions (HReadSeekFirst, HReadSeekLast, ...).

Example

// Recherche des clients à partir du client "Martin"
HReadSeekFirst(Client, Nom, "Martin")
IF HFound(Client) = True THEN
	// Elément trouvé : on annule la recherche
	HCancelSeek(Client, Nom)
	IF ErrorOccurred = True THEN
		Error(HErrorInfo())
		RETURN
	END
	WHILE HOut(Client) = False
		 // Traitement 
		 ...
		 // Lecture du suivant sans utiliser le critère de recherche
		 HReadNext(Client, Nom)
	 END
END
