I have a question. I am using the database class's from MFC. I have everything working fine. I have paramaterized the m_strFilter and this works fine. I am using the paradox driver for the time being as all my old data is in paradox. My question is how does one show a wildcard and what is the wildcard charector in the paramater that substitutes in for the ? in the m_strFilter variable. For instance, I would like the recordset to include all records that have a field that begins with the letter 'A' or with the letter 'B', or all records that begin with 'SMI', or some other type. I basically want to be able to append a wildcard onto the end of the parameter. If this is possible, does the wildcard belong in the m_strFilter, just after the question mark, this would be acceptable in my use, or should it be appended at the end of the CString that is the paramater. Thank you for your help.
