I'm using the VFPOLEDB provider and I am creating a command object like this:

OleDbCommand objCmd = new OleDbCommand("select * from customers where CustomerID = ?");
objCmd.Parameters.Add("CustomerID", "ALFKI");

When I execute this command I am getting an OleDbException that says:

No value given for one or more required parameters.

How do I use the parameter collection to pass parementers to commands?
