Init

Applies to:

Description

Forces an initialization of the structures used in performing Pervasive PSQL extended fetch record set operations based on the parameters supplied in the CacheRows, CacheRejectMax, SelectedFields, and SelectedRecords properties.

Init must be performed prior to making extended operations calls upon initialization and whenever SelectedRecords, SelectedFields, CacheRows, or CacheRejectMax are changed.

Syntax

object.Init

Description



  
    
 

object


    
 

Required. The object placeholder represents an object expression that evaluates to an object in the Applies To list.

Remarks

If the AutoMode is set to True, setting the Init property will also perform the initial extended record set fetch operation (GetNextExtended), which requires logical currency. You may establish logical currency by invoking any of the indexed record operations such as GetFirst, GetEqual, and so on.

The ExtendedOps property must be set to True to enable the extended operations capabilities of the VAccess control.

Example #1 - Automode = True

VAccess1.GetFirst
VAccess1.Init 

Example #2 - Automode = False

Orders.GetFirst
Orders.Init
Orders.GetNextExtended
