 Comments
SetCurrentKey assigns a specified key to a table handle. The key becomes the current key and is used by FindRec, NextRec and other functions until another key is selected. Use NextKey to scan the list of keys for the table to find out which ones are available. Only active keys will be retrieved.

The primary key of the table is the current key, until SetCurrentKey is called. When a secondary key is the current key, you can make the primary key the current key again by calling SetCurrentKey with Key set to an empty Variant.

If a new current key is successfully assigned to the table handle, TRUE is returned. If the requested key does not exist, two things can happen:
