HCancelSeek (Function)
In french: HAnnuleRecherche
ODBCNot 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 was selected by the search functions (HReadSeekFirst, HReadSeekLast, ...).
Note: From version 19, HFSQL is the new name of HyperFileSQL.
Example
// Find the customers from the customer named "Moore"
HReadSeekFirst(Customer, Name, "Moore")
IF HFound(Customer) = True THEN
// Element found: cancel the search
HCancelSeek(Customer, Name)
IF ErrorOccurred = True THEN
Error(HErrorInfo())
RETURN
END
WHILE HOut(Customer) = False
 // Process
 ...
 // Read the next one without using the search criterion
 HReadNext(Customer, Name)
 END
END
