I am creating an MSAccess database from within a VB.NET Windows application using the following method:

            Dim cat As New ADOX.Catalog
            Dim tab As New ADOX.Table
            Dim idx As New ADOX.Index
            Dim col As New ADOX.Column

            cat.Create("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sDB & ";Jet OLEDB:Engine Type=5")

            Do Until sF.Exists = True

            'Database has been created.  Now create table(s)
            tab.Name = "tblInfo"

            tab.Columns.Append("Order_ID", DataTypeEnum.adVarWChar, 12)
            tab.Columns.Append("Order_Date", DataTypeEnum.adVarWChar, 5)
            tab.Columns.Append("Field1", DataTypeEnum.adVarWChar, 5)
            tab.Columns.Append("Field1", DataTypeEnum.adVarWChar, 5)
            idx.Name = "tableindexes"

The problem that i am having is when the database and table is created, all of the columns "Required" property is set to True.  I need to have all columns "Required" property set to "False" so that data is not required.  

How can I do this?
