Sebelum klik tombol import pilih combo boxnya,untuk menentukan pilihan file

Exit Sub
End If
Dim TempPath, TempFile As String
TempFile = Mid(txtfile.Text.Trim, InStrRev(txtfile.Text.Trim, "\") + 1, Len(txtfile.Text.Trim))
TempPath = Microsoft.VisualBasic.Left(txtfile.Text.Trim, (Len(txtfile.Text.Trim) - Len(TempFile)))
Dim cmd As OleDbCommand = New OleDbCommand
cmd.CommandText = "INSERT INTO F4801 (WADCTO,WADOCO,WASFXO,WARCTO,WARORN,WALNID," & _
