using a datarow object or regular sql syntax such as..

Dim oCmdInsertSchool As New MySqlCommand("insert into school (name , db, host) values('" & txtSchool.Text & "', '" & txtDB.Text & "', '" & txtHost.Text & "')", oConn)
oCmdInsertSchool.ExecuteNonQuery()

rather than
dim orow as datarow

orow.items("name") = txtschool.text

thanks
