How to create a checkbox datatype column in a table in VB .net code



I am creating a new boolean column in a MSAccess .mdb database like
this:

Dim Cmd As New OleDb.OleDbCommand("ALTER TABLE m_table ADD boolColumn
YesNo", objConn)
Cmd.ExecuteNonQuery()

, which works fine. But... when the .mdb file is opened in Access the
values for the new column are shown as "-1" and "0"...

Is there a way to make the column display in Access as checkboxes? I
want to be able to do this at runtime in my .net program.

thanks.
