In order to set properties for default controls, you must use the form's DefaultControl method. Note that, although you can use this method to set properties for default controls, not all of a control's properties are available as default properties.

The following properties apply only to default controls and cannot be set for a control that's already on the form or report:

AddColon

AutoLabel

LabelAlign

LabelX

LabelY

TextAlign

To programmatically set the properties for text box controls, follow these steps:

Open the sample database Northwind.mdb.

Create a module and type the following line in the Declarations section if it is not already there:


Option Explicit

Type the following procedure in the module:


Sub SetDefaultProperties()
   Dim frm As Form
   Dim ctl As Control

   Set frm = CreateForm()
   Set ctl = frm.DefaultControl(acTextBox)
   With ctl
       ' Add a label for new textboxes.
       .AutoLabel = True

       ' Do not include a colon in labels for new textboxes.
       .AddColon = False

       ' Align label text to the right for new textboxes.
       .LabelAlign = 3

       ' Place labels for new textboxes 1/4 inch above
       ' and aligned to the left.
       .LabelX = 1440 * .33
       .LabelY = -1440 * .25

       ' Center text in new textboxes.
       .TextAlign = 2
   End With
   DoCmd.SelectObject acForm, frm.Name, False
   DoCmd.Restore
End Sub

To test this procedure, type the following line in the Immediate window, and then press ENTER:
SetDefaultProperties
Note that a new, blank form opens in Design view.

Add a new text box to the form. Note that the label for the new text box does not include a colon, has right aligned text, and appears 1/4 inch above and is left aligned with the text box. Also, note that the text in the new text box is now centered by default.
