HReadSeekLock (Function) In french: HLitRechercheBloque
Available only with this kind of connection
Warning
HReadSeekLock is kept for backward compatibility (this function will still be supported in the forthcoming version). From version 8, this function was replaced by HReadSeekFirst and HReadSeekLast. These functions are used to easily manage the exact-match searches, the generic searches and the searches in filters, ... To benefit from the new features linked to searches in WINDEV, use HReadSeekFirst and HReadSeekLast. These functions allow you to perform an exact-match search by default. Below is the documentation of HReadSeekLock, available in WINDEV 5.5.
