hi
select cobobox and in right you will see the properties
1/datasource make its value the table in dataset you want
2/ ValueMember make its value the coulmn name (name of custeomer)
when your form load you fill dataset
Me.DataSet11.Clear()
Me.OleDbDataAdapter1.Fill(DataSet11)
now the list of comboBox has the names of ur customers
i hope this help
