Yes you are right, use the ? with oledbdataadapter (Humm, there are still data sources other that SQL server in use <s>).

SELECT HINIT,HNAME FROM HWHOA WHERE (HINIT = ?)

You should still get the parameter(s) generated by the wizard. To check go to oledbdataadapter properties, selectcommand, parameters collection. You should see the created parameter list. To test go to oledbdataadapter properties and select preview data. Add in the desired parameter values and hit Fill Dataset. You should get the data returned (At least it works for me).
