Attempts to lock the table.
public void LockTable();
A successful call to LockTable prevents other applications from being able to update the table. It is recommended that you lock tables prior to creating indexes. Any record locks that have been obtained prior to calling LockTable will be released. If the Advantage Client Engine fails to lock the table (e.g., if another user has record locks), then the Advantage Client Engine does not attempt to relock the records that it released.
