First off, thank you for your input Mark.
The connection is set and open. Since execute of the command functions
properly, I think that every thing else is set up properly too.
You are correct that the second parameter is connection information
that must be omitted when a command object is passed in. vtMissing
accomplishes this. It took a lot of digging for me to find that, so I
will share.
vtMissing is a constant provided by ADO when it is #imported into C++.
It is a variant of type VT_ERROR and of value DISP_E_PARAMNOTFOUND. It
is used to specify that a parameter of type variant is omitted. A
parameter of type variant pointer is omitted with &vtMissing (or NULL
if one is sloppy) and a parameter of type string is omitted with a null
string ("").
