GetVSTHandle( ) method

Returns the handle of a valid VST temp-table.

Return type: HANDLE

Access: PUBLIC STATIC

Applies to: Progress.Database.TempTableInfo class

Syntax

GetVSTHandle( INPUT VST-ID AS INTEGER )

VST-ID

An integer expression which evaluates to a valid VST ID. The method raises an error if an invalid value is specified for the ID.

Example:

USING Progress.Database.*.

DEFINE VARIABLE hVst AS HANDLE NO-UNDO.

hVst = TempTableInfo:GetVSTHandle(VSTTableIds:ACTIOTYPE).

The GetVSTHandle() method creates a dynamic temp-table for the VST and returns the handle to the caller. Subsequent calls to the method with the same VST return the same temp-table handle. You cannot call the CLEAR() method on the temp-table handles that you obtain with GetVSTHandle() method. You cannot set the TRACKING CHANGES attribute on the buffer of the VST temp-table handles. Any method on the temp-table that is used to create, update, or delete a record in a temp-table VST will fail.
