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)

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.
