take out the rowsource values of these controls and place the SQL in the tag property of the control.

then on your form_load event add the following

Private Sub Form_Load()


Dim ctrl As Control


For Each ctrl In Me.Controls
Select Case ctrl.Properties("ControlType")
Case acComboBox, acListBox
ctrl.RowSource = ctrl.Tag
Case acSubform
ctrl.Form.RecordSource = ctrl.Form.Tag
Case Else
'do nothing
End Select
Next ctl

Set ctl = Nothing

End Sub


You can also add in to the unload event, the same code above with the rowsource value set to ""

you will notice a dramatic improvement with speed with the above
