Dim con As OleDbConnection = New OleDb.OleDbConnection("provider=microsoft.jet.oledb.4.0;data source=Z:\CAD\Copy of USERS.mdb")

Dim cmd As New OleDbCommand

cmd = New OleDbCommand("Select * from table1 Where Mfg Like '%" & ComboBox1.SelectedItem & "%' And Make Like '%" & ComboBox2.SelectedItem & "%' And RAM Like '%" & ComboBox3.SelectedItem & "%' And GraphicsCard Like '%" & ComboBox4.SelectedItem & "%' And GraphicsVersion Like '%" & ComboBox5.SelectedItem & "%'", con)

con.Open()

Dim da As OleDbDataAdapter = New OleDbDataAdapter(cmd)

Try

Dim ds As DataSet = New DataSet()

Kav,

Change your cmd to this: cmd = New OleDbCommand("Select * from table1 Where Mfg Like %'" & ComboBox1.SelectedItem & "'% And Make Like %'" & ComboBox2.SelectedItem & "'% And RAM Like %'" & ComboBox3.SelectedItem & "'% And GraphicsCard Like %'" & ComboBox4.SelectedItem & "'% And GraphicsVersion Like %'" & ComboBox5.SelectedItem & "'%'", con) See if that works.
