Oke kalau begitu buat form dan desain seperti contoh berikut

komponen yang dibutuhkan :
microsoft DAO 3.51 object library
microsoft excel 10.0 object library
microsoft common dialog control 6.0

untuk scrip codenya sebagai berikut :

Option Explicit
Dim dbSR As Database
Dim rs As Recordset
Dim strcaption, sn
Dim Td As TableDef
Dim i As Single
Dim Recs As Integer, Counter As Integer
Dim Barstring As String, MdbFile As String

Private Type ExlCell
row As Long
col As Long
End Type

Private Sub Command2_Click()

Next

ws.Cells(StartingCell.row + rs.RecordCount + 1, _
StartingCell.col + rs.Fields.Count)).Value = SomeArray
End Sub

Private Sub ToExcel(sn As Recordset, strcaption As String)
Dim oExcel As Object

Dim stCell As ExlCell

DoEvents
On Error Resume Next

Exit Sub
End If
End If
oExcel.Workbooks.Add

CopyRecords sn, objExlSht, stCell
oExcel.Visible = True
oExcel.Interactive = True
Set objExlSht = Nothing
Set oExcel = Nothing
Set sn = Nothing
End Sub

Sub UpdateProgress(PB As Control, ByVal percent)
Dim num$
If Not PB.AutoRedraw Then
PB.AutoRedraw = -1
End If
PB.Cls
PB.ScaleWidth = 100
PB.DrawMode = 10
num$ = Barstring & Format$(percent, "###") + "%"
PB.CurrentX = 50 - PB.TextWidth(num$) / 2
PB.CurrentY = (PB.ScaleHeight - PB.TextHeight(num$)) / 2
PB.Print num$
PB.Line (0, 0)-(percent, PB.ScaleHeight), , BF
PB.Refresh
End Sub
