    Using ADO

    Add Reference: Microsoft ActiveX Data Objects 2.8 Library


    Sub test()
    
        Dim Conn As New ADODB.Connection
        Dim rs As New ADODB.Recordset
        Dim dbPath As String
        Dim aQuery As String
        Dim pword As String
        Dim strcon As String
    
    
        dbPath = ThisWorkbook.Path & "\Database.mdb"
        pword = "abcd"
        aQuery = "SELECT * FROM myTable"
    
        strcon = "Provider=Microsoft.Jet.OLEDB.4.0;" _
                & "Data Source=" & dbPath & ";" _
                & "Jet OLEDB:Database Password=" & pword & ";"
    
        Conn.Open strcon
        rs.Open aQuery, Conn
    
        If Not (rs.EOF And rs.BOF) Then
            MsgBox rs.Fields(0)
        End If
    
        rs.Close
        Set rs = Nothing
        Set Conn = Nothing
    
    End Sub
    

    Using DAO
    Add Reference: Microsoft DAO 3.6 Object Library

    As @Tim highlighted you have missed adding the reference to library.

    Sub test()
    
       Dim db As DAO.Database
        Dim dbPath As String
        Dim aQuery As String
        Dim pword As String
        Dim rs As DAO.Recordset
    
        dbPath = ThisWorkbook.Path & "\Database.mdb"
        pword = "abcd"
        aQuery = "SELECT * FROM myTable"
    
    
        Set db = OpenDatabase(dbPath, True, False, ";PWD=" & pword)
        Set rs = db.OpenRecordset(aQuery)
        rs.MoveFirst
        MsgBox rs.Fields(0)
    
     End Sub

    try this:

    Private Sub CommandButton1_Click()
        Dim db As object, rs as object
        Dim dbPath As String
        Dim aQuery As String
        Dim pword As String, uid as string
    
        dbPath = ThisWorkBook.Path & "\Database.mdb"
        pword = "password"
        uid = "myid"
    
        set db = createobject("adodb.connection")
        with db.open
            .Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & dbPath & _
            ";User ID=" & uid & ";Jet OLEDB:Database Password=""" & pword & """;"
        end with
        aQuery = "SELECT * FROM myTable"
    
        Set rs = db.Execute(aQuery)
        rs.MoveFirst
        MsgBox rs.Fields(0)
    
        db.close
        set rs = nothing
        set db = nothing
    End Sub
