Define OleDbConnection - what? how? thought it was.

I have a form with 3 lablels on it and one text box and one button.
I have made connections to the database using the Data Connection wizzards so now I have an OleDbDataAdapter, OleDbConnection, and DataSet....not sure if that matters but...
When I use the following code in my VB.NET project it underlines OleDbConnection, OleDbCommand  and OleDbDataReader saying "Type OleDbCommand is not defined"
What Do I need to do to define them to get this code to work?

  -----------------------------------------------------------------  

   Dim Connection As OleDbConnection = New OleDbConnection(YourConStr)
        Dim Command As OleDbCommand = New OleDbCommand("SELECT SocSecNo FROM CustomerMaster WHERE SocSecNo='" & txtSocNo.Text & "' AND LastActiveDate BETWEEN '" & Now() & "' AND '" & Now() - 5, Connection)
        Dim DataReader As OleDbDataReader

        Connection.Open()
        DataReader = Command.ExecuteReader
        If DataReader.Read() Then
            'Data Found Display in Labels here
            lblFirstName.Text = DataReader("FirstName")
            lblLastName.Text = DataReader("LastName")
            lblSoc.Text = DataReader("SocSecNo")
        Else
            'No data for the Particular Social ID
            'Either Empty the labels or leave it as it is
            lblFirstName.Text = ""
            lblLastName.Text = ""
            lblSoc.Text = ""
        End If
        DataReader.Close()
        Connection.Close()
------------------------------------------------------------------------
Would this be my connection string (YourConStr)

        Me.OleDbConnection1.ConnectionString = "Jet OLEDB:Registry Path=;Data Source=""C:\Program Files\My APP\DlrData.mdb"" & _
        ";Jet OLEDB:System database=;Jet OLEDB:Global Bulk Transactions=1;Jet OL" & _
        "EDB:Don't Copy Locale on Compact=False;User ID=Admin;Provider=""Microsoft.Jet.OLE" & _
        "DB.4.0"";Jet OLEDB:Database Locking Mode=0;Jet OLEDB:SFP=False;Jet OLEDB:Encrypt " & _
        "Database=False;Jet OLEDB:Create System Database=False;Jet OLEDB:Compact Without " & _
        "Replica Repair=False;Jet OLEDB:Global Partial Bulk Ops=2;Mode=Share Deny None;Ex" & _
        "tended Properties=;Jet OLEDB:Engine Type=4"
